Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. x11vnc-0.9.17/ChangeLog000066400000000000000000001552411500463450600145150ustar00rootroot000000000000002010-12-29 Karl Runge * x11vnc: Use opengl to read screen on macosx.

Note that client side does autorepeating so not a big loss). 2004-07-04 Karl Runge * extend -allow to re-read a file with allowed IP addresses. * improvements to -help text. 2004-07-01 Karl Runge * improve scaled grid calculation to prevent drift (which causes drift in pixel weights and poorer tightvnc compression) * add ":pad" scale option, detect small fraction scale = m/n. 2004-06-28 Karl Runge * round scaled width to multiple of 4 to make vncviewer happy. * allow override of above ":n4" and allow 4 point interpolation to be used even with shrinking ":in". 2004-06-27 Karl Runge * speed up scaling a bit for slow machines (still all floating point) * add no blending option (-scale fraction:nb) 2004-06-26 Karl Runge * add -scale fract for global (not per-client) server-side scaling working more or less OK, needs to be optimized at some point. * remove -hints/-nohints options. 2004-06-17 Karl Runge * simple ~/.x11vncrc config file support, -rc, -norc 2004-06-12 Karl Runge * add -clear_mods -clear_keys for (rare) case where keys are not being released (e.g. Ctrl-C x11vnc thru x11vnc). * export RFB_SERVER_IP and RFB_SERVER_PORT to -accept program so that the tcp 4-tuple is completely specified. * add -storepasswd so storepasswd program not needed 2004-06-05 Karl Runge * rearrange file for easier maintenance, indicating file breakup. * add RFB_CLIENT_COUNT, number of other connected clients to -accept and -gone commands. 2004-05-27 Karl Runge * add view-only passwd via -viewpasswd and 2nd line of -passwdfile 2004-05-21 Karl Runge * -accept: add view-only decision and other improvements. * add -gone command option for when a client leaves. Thanks to Jesus Alvarez for these ideas. * -passwdfile to keep passwd off of cmd line. * -o logfile send stderr to a logfile. 2004-05-14 Karl Runge * improvements to -accept popup: yes/no buttons and timeout. * less fprintf under -q so '-q -inetd' has no stderr output. 2004-05-08 Karl Runge * add -accept some-command/xmessage/popup to prompt local X11 user or otherwise decide to accept an incoming client. * clean up -Wall warnings. 2004-05-05 Karl Runge * enable mouse button -> keystrokes mapping in -buttonmap (mousewheel) * enable keystroke -> mouse button mapping in -remap (touchpad paste) (-remap incompat ':' -> '-', sorry...) * shm OS blacklist (i.e. <= SunOS 5.8) -> -onetile * revert to check_user_input() under -nofb * cleanup: lastmod, remove tile_shm and update_client_pointer, debug output, rfbPort failure. * user friendly last line: 'The VNC desktop is hostname:0' 2004-04-28 Karl Runge * -auth cmdline option for xauthority. * decrease default deferupdate under -nofb. * update_client_pointer() from Edoardo Tirtarahardja. * remove some assumptions about libvncserver defaults. 2004-04-19 Karl Runge * support for cursor positions updates -cursorpos * option for SIGPIPE handling -sigpipe 2004-04-13 Karl Runge * solve problem with sending selection when client initializing (not yet in RFB_NORMAL state). Increase delay to 15s as well. * when threaded: limit rfbMaxClientWait to >= 20 secs and increase it to a huge value unless -rfbwait is supplied. 2004-04-08 Karl Runge * added support for blacking out regions of the screen, primarily for Xinerama usage, options: -blackout -xinerama * Xinerama workaround mouse problem on 'embedded' system, option -xwarppointer (XWarpPointer instead of XTEST) * let -remap option take key remappings on cmdline as well as file. * use cargs fix to test for invalid cmdline options. Add --option. * remove copy_tile, use copy_tiles(..., 1) instead. 2004-03-10 Karl Runge * added reverse connection for vncconnect(1) and other means -vncconnect, -connect host:port, and -connect watchfile * added first pass at user keysym remapping feature via -remap file. Ignores modifier state, need to generalize. * debugging options for users -debug_pointer and -debug_keyboard * clear -passwd from argv for privacy (if OS allows). 2004-02-19 Karl Runge * added handling of clipboard/selection exchange to/from clients, even holds PRIMARY which Xvnc does not do. disable with -nosel. use -noprimary to disable polling of PRIMARY selection. * added -visual option to force framebuffer visual. not really of general use, more for testing and workarounds (e.g. win2vnc fails under 8bpp index color) * improve cleanup and error handling WRT shm and other failures. 2004-01-19 Karl Runge * improvements to pointer event handling primarily during window dragging. check_user_input() for non-threaded and pointer() for threaded. Revert to old way via -old_pointer option. * some memory I/O improvement by using copy_tiles() instead of copy_tile(). New one does rows of tiles at same time. Revert to old way via -old_copytile. * handle case of more mouse buttons on client than on X server. * added -buttonmap option for finer control over button differences. 2004-01-09 Karl Runge * options -allow / -localhost for simple IP based access screening * option -nodragging to skip all screen updates during mouse drags (thanks to Michal Sabala) * option -input_skip to allow users to tune watch_loop dropthru rate * try to avoid wasting RAM for framebuffer under -nofb * cleanup wrt bpp vs. depth 2003-12-08 Karl Runge * add Xbell support using XKEYBOARD extension (disable: -nobell) * add "-nofb" to disable framebuffer, i.e. mouse + keyboard only (!) * add "-notruecolor" to force indexed 8bpp color (when 8bpp) * make alias "-forever" for "-many" From Karl (x11vnc's father) on Apr 2, 2003: New option -nocursor to not display the vncviewer local cursor if user does not want it (also caused some problems with older vncviewers) New option -mouse to show the position of the X server mouse (i.e. lagged from the user's vnc cursor position). Also: -mouseX will try to show the a different cursor (X) when on the root background. New option -many to wait for more connections rather than exiting when the first client(s) disconnect. New option -flashcmap to try to follow installed colormaps under 8bpp indexed color as pointer is moved. New option -nap to watch for low activity and throttle down the polling rate. Useful on shared machines to keep the load down. Experimental option -id to show just that window and not the whole display. Some remaining bugs and inconvenient behavior... (e.g. new toplevels can be unseen) Fixed bug on multi-headed machines where the screen number was being ignored in a number of places. Fixed bug wrt connect_once mode. Now just refuses new clients unless shared rather than terminating all clients. Try to follow changing default colormap under 8bpp indexed color as color cells are added. Needed to pick up HAVE_LIBPTHREAD from autoconf. defined a select() macro for usleep() since usleep is not always thread safe. Catch and exit on errors in the shm setup work (XShmCreateImage, shmget,...) and moved the creation and removal work to separate utility functions. Added signal and X error handlers to try to clean out the shm objects before exiting on interrupt, etc. Improved performance a bit on the memcmp() in scan_display() by checking the whole line first. Added a workaround when threaded where libvncserver may disconnect too early if it does not hear from a client (a small heartbeat is sent). This may not be needed any longer. If -desktop has not been prescribed, try to choose a title based on DISPLAY and the hostname (and window name under -id). x11vnc-0.9.17/Makefile.am000066400000000000000000000003461500463450600147720ustar00rootroot00000000000000ACLOCAL_AMFLAGS = -I m4 SUBDIRS = \ src \ misc desktopdir = $(datadir)/applications desktop_DATA = x11vnc.desktop man_MANS = x11vnc.1 EXTRA_DIST = \ ChangeLog \ README \ NEWS \ tkx11vnc \ $(man_MANS) \ $(desktop_DATA) x11vnc-0.9.17/NEWS000066400000000000000000001605451500463450600134450ustar00rootroot00000000000000x11vnc 0.9.17 2025-04-11 Release Notes New Features: Added option for sending multi-touch commands in uinput. Introduced mousewheel support in uinput. Support for up to 8 mouse buttons and XK_Super_L/R mapping to Meta keys during pipeinput/uinput. Experimental support for double-buffered framebuffer and rawfb DRM/shm key options. Support for OpenBSD in shm_clear. Bug Fixes: Fixed TLS handshake errors with OpenSSL 1.1.x and LibreSSL compatibility issues. Addressed snprintf null destination pointer issue and xfc NULL pointer dereference in cursor. Resolved various allocation and multiplication overflow bugs. Fixed format string issues with size_t arguments and corrected acute accents in man pages. Limited access to shared memory segments to the current user and addressed overly long Unix socket names. Documentation & Maintenance: Refactored and updated README with clearer notes on maintainership, Intel quirks, and FAQs about driver lags. Removed executable bit from text files, fixed typos, and clarified password limit/error messages. Updated issue templates and added FUNDING.yml for community contributions. Keywords added to x11vnc.desktop file. Other Changes: Fixed build issues on 32-bit architectures with 64-bit time_t and support for builds using -fno-common. Addressed gcc -no-common build compatibility. ----------------------------------------------------------------------------- x11vnc 0.9.16 2019-01-05 New in the 0.9.16 x11vnc release: Build fixes. Misc. documentation fixes. ----------------------------------------------------------------------------- x11vnc 0.9.15 2018-02-04 New in the 0.9.15 x11vnc release: Misc. buffer overflow and memleak fixes. Support for OpenSSL 1.1.0. Fix for Debian bug #672435. ----------------------------------------------------------------------------- x11vnc 0.9.14 2015-11-14 New in the 0.9.14 x11vnc release: Added support for the X Composite Extension. For subwindow/appshare modes this allows sharing the respective window/app when it is partially or completely off-screen as XComposite renders the window contents to an off-screen buffer. Before, updating of the window contents would stop once it went even partially off-screen. Added XInput 2 multi-pointer support which allows multiple clients to view and control a single shared screen, all having their own mouse pointers and keyboard foci. For in-depth info, read http://edoc.hu-berlin.de/master/beier-christian-2011-07-19/PDF/beier.pdf, especially section 5.1. Added some support for running under Wayland via the deskshot utility found in the misc/ subdirectory. miscellaneous new features and changes: Separated x11vnc sources from LibVNCServer. The project is now hosted at GitHub under https://github.com/LibVNC/x11vnc/. ----------------------------------------------------------------------------- x11vnc 0.9.13 2010-12-20 New in the 0.9.13 x11vnc release: Improved support for non-X11 touchscreen devices (e.g. handheld or cell phone) via Linux uinput input injection. Additional tuning parameters are added. TSLIB touchscreen calibration is supported. Tested on Qtmoko Neo Freerunner. A tool, misc/uinput.pl, is provided to diagnose uinput behavior on new devices. The env. vars. X11VNC_UINPUT_BUS and X11VNC_UINPUT_VERSION are available if leaving them unset does not work. The Linux uinput non-X11 input injection can now be bypassed: events can be directly written to the /dev/input/event devices specified by the user (direct_abs=..., etc.) A -pipeinput input injection helper script, misc/qt_tslib_inject.pl is provided as a tweakable non-builtin direct input injection method. The list of new uinput parameters for the above two features is: pressure, tslib_cal, touch_always, dragskip, btn_touch; direct_rel, direct_abs, direct_btn, direct_key. The included SSL enabled Java VNC Viewers now handle Mouse Wheel events. miscellaneous new features and changes: In -reflect mode, the libvncclient connection can now have the pixel format modified via the environment variables X11VNC_REFLECT_bitsPerSample, X11VNC_REFLECT_samplesPerPixel, and X11VNC_REFLECT_bytesPerPixel In -create mode the following environment variables are added to fine tune the behavior: FIND_DISPLAY_NO_LSOF: do not use lsof(1) to try to determine the Linux VT, FIND_DISPLAY_NO_VT_FIND: do not try to determine the Linux VT at all, X11VNC_CREATE_LC_ALL_C_OK: do not bother undoing the setting LC_ALL=C that the create_display script sets. The performance of the -create script has been improved for large installations (100's of user sessions on one machine.) In -unixpw mode, one can now Tab from login: to Password. An environment variable, X11VNC_SB_FACTOR, allows one to scale the -sb screenblank sleep time from the default 2 secs. In -rawfb mode, a bug is fixed in setting the number of bits per pixel. Documented that -grabkbd is no longer working with some/most window managers (it can prevent resizing and menu posting.) The macosx deprecated interface GetMainDevice() call is removed. Compile with -DX11VNC_MACOSX_USE_GETMAINDEVICE if needed for an old macosx version... Miscellaneous code cleanup. ----------------------------------------------------------------------------- x11vnc 0.9.12 2010-09-10 New in the 0.9.12 x11vnc release: One can now specify the maximum number of displays that can be created in -create mode via the env. var. X11VNC_CREATE_MAX_DISPLAYS The X11VNC_NO_LIMIT_SHM env. var. is added to skip any automatic shared memory reduction. The kdm display manager is now detected when trying not to get killed by the display manager. miscellaneous new features and changes: A compile error is fixed when using --with-system-libvncserver pointing to LibVNCServer 0.9.7. -nevershared -forever usage mode is documented. Old SuSE broken thread local storage is documented. x11vnc exit cases are documented. A compile bug from forced use of Xdefs.h is worked around. ----------------------------------------------------------------------------- x11vnc 0.9.11 2010-08-08 New in the 0.9.11 x11vnc release: The source tree is synchronized with the most recent libvncclient (this only affects -reflect mode.) The build is fixed for incompatibilities when using an external LibVNCServer (e.g. ./configure --with-system-libvncserver...) The SSL enabled Java VNC Viewer Makefile has been modified so that the jar files that are built are compatible back to Java 1.4. In -reflect mode cursor position updates are now handled correctly. In -create/-unixpw mode, the env. var. FD_USERPREFS may be set to a filename in the user's home directory that includes default username:options values (so the options do not need to be typed every time at the login prompt.) miscellaneous new features and changes: An option -always_inject is provided: Even if there is no displacement (dx = dy = 0) for a VNC mouse event force the pointer to the indicated x,y position anyway. New java viewer debugging and workaround applet parameters: debugKeyboard mapF5_to_atsign forbid_Ctrl_Alt You can set X11VNC_AVAHI_NAME, X11VNC_AVAHI_HOST, and/or X11VNC_AVAHI_PORT environment variables to override the default values. For example: -env X11VNC_AVAHI_NAME=wally When opening the X11 display extra XAUTHLOCALHOSTNAME settings are attempted. ----------------------------------------------------------------------------- x11vnc 0.9.10 2010-05-03 New in the 0.9.10 x11vnc release: IPv6 is now supported for all usage modes: forward and reverse connections, SSL and unencrypted, etc. The included SSL enabled Java VNC viewer applet now supports Chained SSL Certificates (x11vnc -ssl always has.) The applet autodects x11vnc and set GET=1 for faster connecting via HTTPS. A demo CGI script 'desktop.cgi' shows how to create an SSL encrypted, multi-user x11vnc web login desktop service. The user logs into a secure web site and gets his/her own virtual desktop and his browser accesses it with the SSL Java VNC Viewer applet. A serverCert Java Viewer applet parameter is provided. Use an authenticated HTTPS browser connection to set this parameter (the user could set it locally too.) The onetimekey tool has -certonly option for this scheme. The Xdummy script (use Xorg 'dummy' driver instead of Xvfb) no longer requires being run as root. miscellaneous new features and changes: In the Java viewer applet, debugCerts and debugKeyboard parameters are provided. The debugging output of the applet is more readable. Some corner-case bugs (e.g. socket exceptions) are now handled gracefully. Parameters forbid_Ctrl_Alt and mapF5_to_atsign are added. The amount of time to wait for HTTPS applet downloads to finish can be set in env. var. X11VNC_HTTPS_DOWNLOAD_WAIT_TIME. The -xkb mode is automatically enabled if there are more than 4 keysyms per key. -coe is now an alias for -connect_or_exit. The -input_eagerly option enables this LibVNCServer feature (it is like -allinput.) The "%" unix password verification tricks for the -unixpw option are now documented. They also run a command in UNIXPW_CMD. In -create (-svc, etc.) modes, a warning is printed out if Xvfb cannot be found. Xvfb '+kb' option is checked for. The -env CREATE_DISPLAY_OUTPUT=/tmp/mydebug.txt debugging option is documented. Try to preserve user's PATH if possible. In XDMCP connection mode, a test for GDM listening only on IPv6 (::1) is performed. The interface can also be specified via FD_XDMCP_IF. The example scripts connect_switch, ultravnc_repeater.pl, inet6to4 have settings to let them run reliably for long times as daemons. They also support IPv6. IPv6 notes: for some very esoteric cases (e.g. -chatwindow) IPv4 localhost may be required for local IPC. A demo transition tool 'inet6to4' is also included (can be used for other apps.) x11vnc options related to IPv6: -listen6, -6, -no6, -noipv4, -noipv6, and -connect, -proxy. Use STUNNEL_LISTEN in -stunnel mode to have it listen on a particular interface. Also STUNNEL_PROG. New remote control query options: pointer_x, pointer_y, pointer_same, pointer_root, and pointer_mask. A demo script using them misc/panner.pl is provided. Remote control change of -clip option will not create new framebuffer if the size has not changed (for panner.pl) The X11VNC_DISABLE_SSL_CLIENT_MODE env. var. can be set to disable SSL client role in reverse connections. This means the VNC viewer side must be in SSL client role. UltraVNC repeater operation can benefit from this. The SSL_INIT_TIMEOUT is increased to 1 hour if 'repeater' is detected in a reverse connect string. The X property X11VNC_TRAP_XRANDR can be set on a desktop to force x11vnc to use the -xrandr screen size change trapping code. The -sslScripts option prints out the SSL certificate management scripts. Suggest '-auth guess' and '-findauth' if X connection fails. The TightVNC sercurity type (TightVNC features enabler) now works for RFB version 3.8. RECORD scroll detection is now working with the new gtk/gdk scroll mechanism. Set X11VNC_SCROLL_MUST_EQUAL to disable.

The use of '-auth guess' will use the XAUTHORITY that -findauth reveals. This can be handy in with the lastest GDM where the ability to store cookies in ~/.Xauthority has been removed. If x11vnc is running as root (e.g. inetd or XDM/GDM/KDM) the FD_XDM=1 mode will be tried if the above -findauth or '-auth guess' command fails; it will find the correct XAUTHORITY for the given display (this works for XDM/GDM/KDM if the login greeter panel is up or if someone has already logged into an X session.) You can also set -env FD_XDM=1 to force it to be done on the first try. The -unixpw_system_greeter option, when used in combined unixpw and XDMCP FINDCREATEDISPLAY mode (e.g. -xdmsvc), enables the user to press Escape to jump directly to the XDM/GDM/KDM login greeter screen. This way the user avoids entering his unix password twice at X session creation time. For subseqent logins to the same session, he uses the regular x11vnc unixpw "login:" prompt. Also, the unixpw login panel now has a short help displayed if the user presses 'F1' that lists the options. The -appshare option enables simple application sharing based on the -id/-sid mechanism. Every new toplevel window that the application creates induces a new viewer window via a reverse connection. The -id/-sid and -connect options are required. Run 'x11vnc -appshare -help' for more info. Heuristics are applied to try to determine if the X display is currently in a Display Manager Greeter Login panel (e.g. GDM.) If so, x11vnc's creation of any windows and use of XFIXES are delayed. This is to try to avoid x11vnc being killed after the user logs in if the GDM KillInitClients=true is in effect. So one no longer needs to set KillInitClients=false in gdm.conf. Note that in recent GDM the KillInitClients option has been removed. Also delayed is the use of the XFIXES cursor fetching functionality; this avoids an Xorg bug that causes Xorg to crash right after the user logs in. x11vnc now tries to be more aggressive in keeping up with VNC client's framebuffer update requests. Some broken VNC clients continuously spray these requests at VNC servers (regardless of whether they have received any updates or not.) The -extra_fbur option allows one to fine tune the setting. The "-display WAIT:cmd=...", -find, -create modes now work correctly for the user-supplied login program scheme "-unixpw_cmd ...", as long as the login program supports running commands specified in the environment variable "RFB_UNIXPW_CMD_RUN" as the logged-in user. The mode "-unixpw_nis ..." has also been made more consistent. The username option "tag=..." can be used to set FD_TAG. The -stunnel option (like -ssl but uses stunnel as an external helper program) now works with the -ssl "SAVE" and "TMP" special certificate names. The -sslverify and -sslCRL options now work correctly in -stunnel mode. Single port HTTPS connections are also supported for this mode. The remote control command -R can be used to instruct x11vnc to resend its most recent copy of the Clipboard, Primary, or Cutbuffer selections: "x11vnc -R resend_clipboard", "x11vnc -R resend_primary", and "x11vnc -R resend_cutbuffer". miscellaneous new features and changes: The fonts in the GUI (-gui) can now by set via environment variables, e.g. -env X11VNC_FONT_BOLD='Helvetica -16 bold' and -env X11VNC_FONT_FIXED='Courier -14'. The value of the -timeout option is now also used for the timing out of reverse connections. The -timeout exit will occur if no client has made it to normal operating state (instead of merely trying to connect.) One can add extra URL parameters to the HTTPS (-ssl) urls via X11VNC_EXTRA_HTTPS_PARAMS without needing to edit index.vnc. E.g.: -env X11VNC_EXTRA_HTTPS_PARAMS='?GET=1' One can make the libvncserver HTTP (non-SSL) server listen on localhost: -env X11VNC_HTTP_LISTEN_LOCALHOST=1 (this way only the single-port VNC+HTTPS is exposed to the network.) Warnings are printed out at startup if $DISPLAY appears to start with "localhost:" (SSH X11 forwarding) or "hostname:" (remote X display; will fail w/o -noshm) The -solid option now uses the DBUS_SESSION_BUS_ADDRESS env. var if available. The -solid option now works in xfce. If available, the dbus_launch(1) will be used in FINDCREATEDISPLAY for gnome sessions. The bcx_xattach remote control command was added to facilitate xattach and x2x desktop cursor switching. Other new remote control commands: grab_state, ping:mystring, grablocal, resend_cutbuffer, resend_clipboard, resend_primary, keycode, keysym, fakebuttonevent, ptr, sleep, get_xprop, set_xprop, wininfo, pointer_pos, mouse_xy, noop, guess_dbus, DIRECT:query. Remote control scripting, -query_retries, and -remote_prefix were also added. In -rawfb mode the X display will not be opened at all unless the -rawfb string is prefixed with '+' or -display was specified on the cmdline. For multiple, separate x11vnc instances on the same X display, one can rename the X11VNC_REMOTE, X11VNC_TICKER, and VNC_CONNECT property names to unique ones. The -showrfbauth option prints out the VNC rfbauth password. The XDAMAGE mechanism is now automatically disabled for a period of time if a game or screensaver generates too many XDAMAGE rectangles per second. This avoids the X11 event queue from soaking up too much memory. x11vnc does not switch on server autorepeat if any keys are pressed down to work around a recent Xorg server and/or gnome bug where the key will never stop repeating. Thse list of current clients is kept more up-to-date in the tkx11vnc gui. Bugs in the gui setpass mode have been fixed. Threads stability is further improved. See under the -threads option help info about -env X11VNC_THREADS_NEW_FB_SLEEP=ms There is an experimental workaround: "-env X11VNC_WATCH_DX_DY=1" that tries to avoid problems with poorly constructed menu themes that place the initial position of the mouse cursor inside a menu item's active zone. The crypt(3) function is now declared inside the x11vnc code on all platforms (not just Linux). To disable this, set CPPFLAGS='-DDO_NOT_DECLARE_CRYPT' while configuring. (crypt is declared to avoid problems with header files.) Error reasons are printed for -storepasswd failures. Two scripts are added to x11vnc/misc: connect_switch and ultravnc_repeater.pl For more information: http://www.karlrunge.com/x11vnc/ http://www.karlrunge.com/x11vnc/x11vnc_opts.html x11vnc -help | less ----------------------------------------------------------------------------- x11vnc 0.9.8 2009-07-08 New in the 0.9.8 x11vnc release: Better reliability for the Java Viewer applet when connecting through a Web Proxy via HTTPS. A proxy hostname and port can be specified via applet parameters. Proxy Authentication via Auth-Basic is supported. More x11vnc printout in -ssl is provided to help troubleshoot this mode and other ssl connections. Stability improvements to -threads mode. Running x11vnc this way is more reliable now. Threaded operation sometimes gives better interactive response and faster updates. The threaded mode now supports multiple VNC viewers using the same VNC encoding (some only on Linux or enabled at build time.) The threaded mode can also yield a performance enhancement in the many client case (e.g. class-room broadcast.) We have tested with 30 to 50 simultaneous clients. See also -reflect. miscellaneous new features and changes: x11vnc automatically tries to work around an Xorg server bug involving infinitely repeating keys when turning off key repeating. Use -repeat if the automatic workaround fails. Also, the environment variable X11VNC_IDLE_TIMEOUT (seconds) is provided. In -reflect mode the environment variable X11VNC_REFLECT_PASSWORD is provided. The -clip mode works under -rawfb. The -nounixpw option can disable unixpw mode if an earlier option enables it (e.g. -svc). Scroll detection is skipped for windows with 'OpenOffice' in their name. For more information: http://www.karlrunge.com/x11vnc/ http://www.karlrunge.com/x11vnc/x11vnc_opts.html x11vnc -help | less ----------------------------------------------------------------------------- x11vnc 0.9.7 2009-03-31 New in the 0.9.7 x11vnc release: Basic support for building with VirtualGL's TurboVNC (an enhanced TightVNC for fast LAN high framerate usage) encoding and TightVNC modifications. More info: http://www.karlrunge.com/x11vnc/faq.html#faq-turbovnc and x11vnc/misc/turbovnc/README. The -ncache_cr option has been fixed and so in -ncache mode smooth opaque window motions are now work correctly. Try it out to see how smooth it is even on a slow link. Support for Linux text consoles (virtual terminals, e.g. 1-6) is provided via, e.g., 'x11vnc -rawfb vt2' (for virtual terminal #2). This is like LinuxVNC (i.e. text only), it avoids using /dev/fb and uses /dev/vcsaN instead (the '-rawfb console' mode uses /dev/fb.) With /dev/vcsaN the text terminal is accessible even it if is not the currently active one. The -rawfb option now supports framebuffers with bits per pixel less than 8 (e.g. 4 or 1 bpp.) Reverse connections now work in Anonymous Diffie Hellman SSL/TLS mode. Reverse connections also work for VeNCrypt and ANONTLS modes. miscellaneous new features and changes: The included SSL enabled UltraVNC java viewer now has a configurable [Home] entry in the drives drop down menu. In the -create, -svc, etc. modes one can now specify a range of X displays to ignore in X11VNC_SKIP_DISPLAY. Improvements and bugfixes were made to the find_display and create_display scripts. FD_EXTRA option is provided. The '-rawfb video' option finds the video device file more carefully. The -rmflag option allows a new way to indicate to other applications that x11vnc has started. All of the java applet parameters are now documented in the classes/ssl/README file. There is now a "sendbell" remote control command. A one-time -padgeom once:WxH mode is added. Improvements to the CUPS Terminal Services helper mode. If the X display cannot be opened normally then the env. var. XAUTHLOCALHOSTNAME=localhost is tried. Bugfix for selection transfer to a now non-existent X window (Thunderbird can cause this.) Related, the env. variable LIBXCB_ALLOW_SLOPPY_LOCK is now set by default. Bugfix for -8to24 mode due to nonstandard indexed color support. The libvncserver and x11vnc autoconf/automake settings have been improved. libXrandr include file is now found on Solaris. For more information: http://www.karlrunge.com/x11vnc/ http://www.karlrunge.com/x11vnc/x11vnc_opts.html x11vnc -help | less ----------------------------------------------------------------------------- x11vnc 0.9.6 2008-12-10 New in the 0.9.6 x11vnc release: x11vnc's SSL encryption is extended to support the VeNCrypt and TLS (older; vino) SSL/TLS security type extensions to VNC. Anonymous Diffie-Hellman key exchange (-ssl ANON) and Certificate Revocation List support (-sslCRL) is added to the SSL encryption mode. The Java viewer applet can now be served up through the VNC port (5900) in addition to the normal HTTP port (5800) via the -http_oneport option. Previously this only worked for SSL connections and HTTPS. The "-rfbport PROMPT" mode presents a simple gui for the user to select a port for the x11vnc service and a few other settings. This enables a menu entry for naive users that is included in x11vnc.desktop. If x11vnc is not built with the Avahi Zeroconf library an external helper program (avahi-publish or dns-sd on Mac OS X) is used instead. miscellaneous new features and changes: The default mode for '-ssl' is now the '-ssl SAVE' mode; i.e. the generated certificate is saved and reused in subsequent sessions rather than being discarded. Use '-ssl TMP' recover the old way. This change made to for it to be more likely that the VNC Viewer can save the accepted cert for future authentications. The solid background color option works on the Mac OS X console. The -reopen option enables x11vnc to try to re connect to the X display if GDM (or other display manager) kills it just after the user logs in. The -dhparams option can be used to point to your own Diffie Hellman parameters. The -setdefer option allows tuning how quickly updates will be sent. Default setting tuned. The option -zeroconf is now an alias for -avahi/-mdns. In pipeinput mode, the pipe filehandle is now closed when x11vnc exits. The -sshonly option turns off VeNCrypt and TLSVNC (vino) mod leaving only the standard SSL (i.e. vncs://) For testing, the option -rand in an alias for -rawfb rand -nopw Minor tweaks to improve CUPS Print tunneling. For more information: http://www.karlrunge.com/x11vnc/ http://www.karlrunge.com/x11vnc/x11vnc_opts.html x11vnc -help | less ----------------------------------------------------------------------------- x11vnc 0.9.5 2008-10-24 New in the 0.9.5 x11vnc release: Symmetric key encryption using the RC4, AES, Blowfish, and 3DES ciphers is supported via the -enc cipher:keyfile option. The SSVNC unix viewer 1.0.20 and later supports these encryption methods. Server-side scaling can now have different scale factors along the horizontal and vertical axes. E.g. -scale 1280x1024 (same as -geometry 1280x1024) or -scale 0.8x0.75 The -chatwindow option allows a chat window to appear on the X console during UltraVNC chats (requires the SSVNC viewer package.) miscellaneous new features and changes: The HTTP Java viewer applet jar, classes/VncViewer.jar, has been updated with an improved implementation based on the code used by the classes/ssl applets. A description and instructions are now printed out when X_ShmAttach fails if one tries to attach to a remote $DISPLAY (i.e. $DISPLAY is on a different machine from the machine x11vnc is running on; this often happens with SSH X redirection, X terminal servers, etc). The -allow option now works correctly in -ssl mode. The -remap option now works on the MacOSX console. For more information: http://www.karlrunge.com/x11vnc/ http://www.karlrunge.com/x11vnc/x11vnc_opts.html x11vnc -help | less ----------------------------------------------------------------------------- x11vnc 0.9.4 2008-09-17 New in the 0.9.4 x11vnc release: Reverse VNC connections (-connect and -connect_or_exit options) work in the -find and -create X session FINDCREATEDISPLAY modes. Reverse VNC connections (either normal or using SSL) can use a Web Proxy, a SOCKS proxy, the UltraVNC repeater proxy, an SSH connection, or even a CGI URL to make the outgoing connection (-proxy option). Forward connections can use the -ssh option to set up a reachable redirection. Support for the ZYWRLE encoding is added, this is the RealVNC ZRLE encoding extended to do motion video and photo regions more efficiently by way of a Wavelet based transformation. The session finding and creating modes (-find and -create) have been improved to be more reliable and also provide a new desktop types (xfce) and new service redirection options. Support for indexed colormaps (PseudoColor) with depths other than 8 is provided (depths 1 to 16 now work). Java viewer applet source code is provided in the x11vnc 0.9.4 tarball so now everything can be built from source. miscellaneous new features and changes: To unset Caps_Lock, Num_Lock and raise all keys in the X server use -clear_all, or by remote control 'x11vnc -R clear_all' The -autoport option gives more control over the server port range that probes. The -ping option can be used to help keep idle connections alive. The -finddpy and -listdpy utilities help to debug and configure the -find, -create, and -display WAIT:... modes. Some automatic detection of screen resizes are handled even if the -xrandr option is not supplied. The -advertise_truecolor option can workaround some VNC viewer incompatibilities with PseudoColor. The option '-clip xinerama0' can be used to clip to the first Xinerama sub-screen, etc. If a fast framebuffer read rate is detected the -wait and -defer parameters are reduced to 10 and 15 msec, respectively. Pasting of the selection/clipboard into remote applications (e.g. Java) is improved. Usage with dvorak keyboards is improved. The option -macuskbd is available on MacOSX to use the original US keyboard code. Via a compiler option (-DENABLE_GRABLOCAL) one can use the -grablocal n option to filter VNC client input if someone at the console has done mouse or keyboard input n secs ago. The -sleepin option can now sleep a random amount of time between min and max time delays (-sleepin min-max). For more information: http://www.karlrunge.com/x11vnc/ http://www.karlrunge.com/x11vnc/x11vnc_opts.html x11vnc -help | less ----------------------------------------------------------------------------- x11vnc 0.9.3 2007-10-04 New in the 0.9.3 x11vnc release: This release provides client-side caching to improve interactive response. Almost no VNC viewers implement caching which is why VNC is slow compared to other remote graphics protocols. The x11vnc caching will work with any VNC viewer, but they will not hide the pixmap cache region that is below the main desktop (one must adjust the window manually). The SSVNC Unix VNC viewer, however, automatically detects and hides the region. To enable caching, supply "-ncache n" to x11vnc, where the number n, e.g. 10, indicates how much memory to devote to the caching scheme. See http://www.karlrunge.com/x11vnc/#faq-client-caching For more information: http://www.karlrunge.com/x11vnc/ http://www.karlrunge.com/x11vnc/x11vnc_opts.html x11vnc -help | less ----------------------------------------------------------------------------- x11vnc 0.9.2 2007-06-18 New in the 0.9.2 x11vnc release: A compile-time bug is fixed for when the OpenSSL library is not available or --without-ssl is supplied; previously the build would fail. One can configure x11vnc via "configure --with-system-libvncserver" to use a system installed libvncserver library instead of the one bundled in the release tarball. If UltraVNC file transfer or chat is detected, then VNC clients are "pinged" more often to prevent these side channels from becoming serviced too infrequently. In -unixpw mode in the username and password dialog no text will be echoed if the first character sent is "Escape". This enables a convenience feature in SSVNC to send the username and password automatically. miscellaneous new features and changes: When building from the CVS tree --with-x11vnc must be supplied if you want x11vnc to be built. The LibVNCServer release tarball no longer contains the x11vnc source. For more information: http://www.karlrunge.com/x11vnc/ http://www.karlrunge.com/x11vnc/x11vnc_opts.html x11vnc -help | less ----------------------------------------------------------------------------- x11vnc 0.9.1 2007-05-24 New in the 0.9.1 x11vnc release: A new Unix username identification scheme is provided when SSL client certificates are used to authenticate VNC viewers. The username is extracted from the 'Subject' section of the cert. The option is "-users sslpeer=" which, like "-users unixpw=" already does, will cause a switch to the Unix user. This is useful for the -find and -create options that try to find an existing X session associated with the user or create a new one. The UltraVNC Java Viewer has been modified to support SSL connections. Some bugs were also fixed and some improvements added. A patch file and a compiled jar file (UltraViewerSSL.jar and SignedUltraViewerSSL.jar in the classes/ssl directory) are provided in the x11vnc package. For the -user option groups are now handled better by using initgroups(3), or if finer control is needed one can use: "-users user1.group1,..." When SSL client certification is being used and external login programs are being used the env. var. RFB_SSL_CLIENT_CERT is set to the clients certificate. Set X11VNC_SSLPEER_CN to use the Common Name instead of the certificate email address to find the unix username. miscellaneous new features and changes: The -wait and -defer defaults were lowered from 30 to 20 milliseconds, set the values explicitly if this increases the load too much for your liking. In -create mode where a Xvfb session is started, mwm was added as a session type. setpgrp(2) is used for the spawned process if available. The XKEYBOARD extension is enabled (+kb, but it doesn't seem to always work). TrueColor is forced to be the default visual (recent Xvfb seem to choose DirectColor, this is likely a bug) One can also force creating a new Xvfb by setting the env. var. X11VNC_FINDDISPLAY_ALWAYS_FAILS (not exactly clear what this would be used for). The WAITBG env. var. enables -display WAIT:... to take place in the background. One can specify the X11VNC_SKIP_DISPLAY env. var. for a list of displays to exclude in the FINDDISPLAY action. This can also be specified via nd=... as a -unixpw login option. setsid() or setpgrp() is called for the external command spawned by the -gone option (since it may be long lived, e.g. a screen locker). The script "onetimekey" utility is provided in the classes/ssl subdirectory that allows a (very long) string representing a Client SSL certificate to be provided by the authenticating client, or via https cgi script (e.g. after a web login). Some bugs were fixed in the libvncserver implementation of UltraVNC file transfer.

Enable via "-avahi". Implementations of UltraVNC's TextChat, SingleWindow, and ServerInput extensions (requires ultravnc viewer or ssvnc Unix viewer). They toggle the selection of a single window (-id), and disable (friendly) user input and viewing (monitor blank) at the VNC server. Short aliases "-find", "-create", "-svc", and "-xdmsvc" for commonly used FINDCREATEDISPLAY usage modes (to find the user's display or create one, etc). Reverse VNC connections (viewer listening) now work in SSL (-ssl) mode. miscellaneous new features and changes: New options to control the Monitor power state and keyboard/mouse grabbing: -forcedpms, -clientdpms, -noserverdpms, and -grabalways. A simple way to emulate inetd(8) to some degree via the "-loopbg" option. Monitor the accuracy of XDAMAGE and apply "-noxdamage" if it is not working well. OpenGL applications like like beryl and MythTv have been shown to make XDAMAGE not work properly. For Java SSL connections involving a router/firewall port redirection, an option -httpsredir to spare the user from needing to include PORT=NNN in the browser URL. A -sleepin n option to delay startup by n seconds to let redirs and listening clients to get started. TightVNC file transfer is now off by default; enable via -tightfilexfer For more information: http://www.karlrunge.com/x11vnc/ http://www.karlrunge.com/x11vnc/x11vnc_opts.html x11vnc -help | less ----------------------------------------------------------------------------- x11vnc 0.8.4 2007-02-01 New in the 0.8.4 x11vnc release: Native Mac OS X Aqua/Quartz support. It exports the full display (no X11 server, etc). This provides an alternative to OSXvnc; some activities are faster (and see the client-side caching feature -ncache in the 0.8.5 development version for more speedups). x11vnc can act as a VNC reflector/repeater using the "-reflect host:N" option. This is useful for large classroom broadcasting or demos. You set up a number of reflectors to spread the network and CPU load around for better response. A new login mode: "-display WAIT:cmd=FINDCREATEDISPLAY -unixpw ..." that will Create a new X session (Xvfb, Xdummy, or Xorg) for the user if it cannot find the user's X session display via the FINDDISPLAY method. It will be re-found upon reconnection. This enables a simple "terminal services" mode based on Unix username and password and where the user does not have to memorize their VNC display number, etc. miscellaneous new features and changes: Option -nodpms to avoid problems with programs like KDE's kdesktop_lock that keep restarting the screen saver every few seconds even with active VNC clients connected. The "-N" option couples the VNC Display number to the X Display number. E.g. if your X DISPLAY is :2 then the VNC display will be :2 (i.e. using port 5902). If that port is taken x11vnc will exit. Wireframe copyrect detection for local user activity (e.g. someone sitting at the physical display moving windows). You can disable this with the -nowireframelocal option. To automatically fix the common mouse motion problem on XINERAMA (multi-headed) displays, the -xwarppointer option is enabled by default when XINERAMA is active. You can disable this with the -noxwarppointer option. By default in -reflect mode -shared is implied (it makes sense), use -noshared after the -reflect option to disable this. The -prog option lets you specify the full path (argv[0]) to the program, in case it is spawned by inetd/tcpd and cannot determine its path. The path is needed for the -http option to guess the http classes directory. Usually not needed, but there are many options for tuning the native Mac OS X mode: -macnodim -macnosleep -macnosaver -macnowait -macwheel -macnoswap -macnoresize -maciconanim -macmenu. An option -debug_xdamage has been added for debugging and profiling. For more information: http://www.karlrunge.com/x11vnc/ http://www.karlrunge.com/x11vnc/x11vnc_opts.html x11vnc -help | less ----------------------------------------------------------------------------- x11vnc 0.8.3 2006-11-13 New in the 0.8.3 x11vnc release: The -ssl option provides SSL encryption and authentication natively via the www.openssl.org library. One can use from a simple self-signed certificate server certificate up to full CA and client certificate authentication schemes. The -sslverify option allows for authenticating VNC clients via their certificates in either -ssl or -stunnel modes. Certificate creation and management tools are provide in the -sslGenCert, -sslGenCA, and related options. An SSL enabled Java applet VNC Viewer applet is provided in classes/ssl/VncViewer.jar. The applet may also be loaded into the web browser via HTTPS, i.e one can use the VNC port, e.g. https://host:5900/ See our "Enhanced TightVNC Viewer" project, for native SSL enabled viewers. The -unixpw option supports Unix username and password authentication. The -ssl or -localhost and -stunnel options (or detection of an SSH tunnel) are enforced in this mode to prevent password sniffing. Coupling -unixpw with -display WAIT:cmd=FINDDISPLAY provides a way to allow a user to login with their UNIX password and have their display connected to automatically. Hooks are provided in the -unixpw_cmd and "-passwdfile cmd:,custom:..." options to allow you to supply your own authentication and password lookup programs (e.g. LDAP). The "-ultrafilexfer" alias is provided and improved UltraVNC filetransfer rates have been achieved. The -rotate option enables you to rotate or reflect the screen before exporting via VNC. This is intended for use on handhelds and other devices where the rotation orientation is not "natural". miscellaneous new features and changes: Similar to -ssl, the -stunnel option starts up a SSL tunnel server stunnel (that must be installed separately on the system) to allow only encrypted SSL connections from the network. Option -sslnofail to exit immediately if there are any SSL connection failures. A simpler variant of -unixpw is the -unixpw_nis option that works in environments where the encrypted passwords are readable, e.g. NIS. x11vnc can be configured and built to not depend on X11 libraries "./configure --without-x" for -rawfb only operation (e.g. embedded linux console devices). Add -cursor_drag to change the mouse cursor during Drag and Drop, etc. Under the "-connect_or_exit host" option x11vnc will exit immediately unless the reverse connection to host succeeds. The "-rfbport 0" option disables TCP listening for connections (useful for this mode). The "-rawfb rand" and "-rawfb none" options are useful for testing automation scripts, etc., without requiring a full desktop. Reduced spewing of information at startup, use "-verbose" (also "-v") to turn it back on for debugging.

This enables, for example, viewing and interacting with Qt-embedded/Qtopia-Core apps on Linux-based handhelds, etc. Options: -rawfb cons, -pipeinput UINPUT More info: http://www.karlrunge.com/x11vnc/#faq-qt-embedded Extension of the display option: -display WAIT: to delay x11vnc's opening of the X display until a VNC client connects (useful built-in: -display WAIT:cmd=FINDDISPLAY, to find a user's display and Xauthority data). Options -grabkbd and -grabptr have x11vnc try to grab the X display when VNC clients are connected to prevent a (non-malicious) user at the physical X display from performing keyboard or mouse input. E.g. remote help-desk support. miscellaneous new features and changes: -allowedcmds option to fine-tune which external commands may be run by x11vnc, rather than shutting them all off with -nocmds. -env VAR=VALUE convenience option to avoid the need of setting environment variables before starting x11vnc. -allinput option to enable libvncserver handleEventsEagerly parameter (not clear it yields an improvement). -rawfb rand fun/testing option using /dev/urandom as a fb. -license, -copying, -warranty option.

(the latter gives a simple keyboard control of a tv tuner; see also the -freqtab option for stations). FBPM support for hardware that provides framebuffer power management (it needs to be disabled when vnc clients are connected). The -usepw option will require x11vnc to use a password of some sort or otherwise exit immediately. Put it in your ~/.x11vncrc so you don't forget. The command "x11vnc -storepasswd" will prompt for a password without echoing and save it in ~/.vnc/passwd The X CLIPBOARD selection is managed in addition to the X PRIMARY selection. miscellaneous new features and changes: Convenience option for accessing the Linux console: -rawfb cons etc. (requires /dev/fb0 to be working). clipboard/cut-text input can now be managed on a per-client basis. -capslock and -skip_lockkeys options can help make CapsLock work better. The Xdummy wrapper script is included in the source tree. A mode "-gone popup" as been added. -24to32 option to avoid 24bpp problems. -xinerama is on by default.

The -passwdfile option has been enhanced to handle any number of full-access and view only passwords in an easy to maintain format, and additional features. The -8to24 option enables multi-depth viewing on systems that do not support -overlay. The 8bpp regions are transformed to depth 24 TrueColor before exporting via VNC. The x11vnc source code has gone through a major reorganization. The build has been enhanced and many bugs fixed. miscellaneous new features and changes: -afteraccept option is like -accept however it enables running a user supplied command after client authentication has taken place. The RFB_* environment variables have been extended. -loop option will run x11vnc in an outer loop restarting each time (useful for situations where the X server restarts often). -slow_fb allows for slow polling for special purpose applications (e.g. video). -blackout noptr,WxH+X+Y,... will prevent the pointer from going into a blacked out region.

DAMAGE sends events indicating damaged (modified) screen rectangles to x11vnc. These are used as hints to focus the polling and also if the rectangle is below a size threshold it is accepted unconditionally (i.e. dragged in from the framebuffer). Tuning is possible with -xd_area. DAMAGE is available on recent Xorg servers and Solaris 10. -wireframe: Heuristics are used to guess when a window is being moved or resized and during this period show only a moving wireframe outline. Just like on video cards in the 90's, remember? This is to avoid window "lurching" when you move or resize one opaquely. Also, -wirecopyrect applies the VNC CopyRect encoding for the moved window. Both are on by default, use -nowireframe or -nowirecopyrect to disable (aka -nowf and -nowcr). -scrollcopyrect: Sniff the X11 protocol via the RECORD extension and to try to detect window scrolls (e.g. via scrollbar, Up/Down arrow, etc). When detected, the VNC CopyRect encoding is applied to the scrolled regions for a speedup. The contents of the scrolling window may only be approximate while it is being scrolled: e.g. tearing, bunching-up, etc. The heuristics will also miss scrolls by certain toolkits or applications, so those will still happen the slow way. To disable use -noscrollcopyrect (aka -noscr). Tuning is also available, see the -help entry. -listen: Makes x11vnc listen only on a single network interface. -localhost now implies '-listen localhost'. -rawfb: Instead of polling an X server framebuffer, poll a raw one (i.e. a mapped file or a shm segment). E.g. for the linux framebuffer device: -rawfb map:/dev/fb0@1024x768x32 This is a bit out of x11vnc's scope but may have some interesting applications. Perhaps /dev/video? -pipeinput: Pipe the VNC user's pointer and keyboard input events to a helper program you provide. Two examples are in misc/vcinject.pl and misc/slide.pl. Primarily intended for use with -rawfb to somehow kludge-up user input, but it can also be used by itself. Improvements for the magnification scaling case (e.g. -scale 2) for use in low vision applications. It is faster and no-blending :nb now works correctly. More safety measures are taken WRT remote-control in the default mode. See the -unsafe, -safer, -privremote, and -nocmds options. The GUI has been improved, and running with the options "-gui icon" presents a small, simple gui instead of the full blown one, and "-gui tray" attempts to embed the small icon in the system tray. Use "-gui tray=setpass" to prompt for session password creation at startup. miscellaneous new features and changes: -xkb: a simple test is performed at startup to see if it is a good idea to apply -xkb mode for the current keyboard keymapping (i.e. if keysyms like !, @, [ are otherwise unavailable). To disable use -noxkb. ISO_Level3_Shift vs. Mode_switch: Set things up in -xkb mode to prefer ISO_Level3_Shift over Mode_switch for modtweaking. No override; let me know if this causes problems. -add_keysyms is now the default, use -noadd_keysyms to disable. the added keysyms are periodically deleted. -remap DEAD: shorthand for mapping many "dead" keysyms to their "un-dead" counterparts, e.g. grave -> dead_grave. For some VNC viewers that are unable to send the dead keysym. -skip_dups: skip impossible duplicate key events sent by some VNC viewers. -noskip_dups to disable (currently off by default). -sloppy_keys: try to handle sloppy keyboarding (esp. between different language keyboards) where, say, Shift is released before the key. -norepeat N: ping-pong N times if something else on the desktop restores key autorepeating (e.g. session startup). Default 2. Also, If the VNC client is idle for 5 min. autorepeat is restored. -wait_ui: If there is very recent user input, cut the -wait sleep time by the specified factor (default 2.0). -nowait_bog: Detection is now in place to watch for polling "bogging down" (e.g. lots of scrolling text from a long build in a terminal) and to sleep more. Use -nowait_bog to disable. -flag: write PORT=5900 to a flag file to aid wrapper scripts. -http: try to guess what the -httpdir should be and if found enable http listening. -clip WxH+X+Y: only show the specified rectangle not the entire screen. cursors are now scaled by default under -scale, use -scale_cursor to modify this behavior. -arrow n: select from some different arrow cursors (ignored under XFIXES cursor grabbing mode). -nolookup: disable DNS lookups for broken environments. -seldir: fine tune and debug selection transfer. build-time customization macros: SHARED, FOREVER, NOREPEAT, REMOTE_CONTROL, SMALL_FOOTPRINT, default passwd, etc. see the top of the x11vnc.c for more info. -xtrap: DEC-XTRAP extension is supported for legacy systems with insufficient XTEST extension (X11R5). -shiftcmap: for legacy systems with non-standard colormap values. -noxrecord: do not use the RECORD extension for anything (currently only -scrollcopyrect and grabserver watching use it). -grab_buster: fork a helper thread to watch for XGrabServer deadlock in x11vnc and break the grab. Under -scrollcopyrect there is a small window where x11vnc is vulnerable to this deadlock. -dbg: A "crash shell" with tips on debugging will be presented instead of exiting when a fatal error occurs. -fixscreen: periodically refresh the screen to get rid of painting errors, etc. induced by new features, jpeg compression, etc. -speeds: Tell x11vnc what the network and fb speeds are instead of having it try to measure them. (these speeds are used by various features, such as -wireframe, -scrollcopyrect, etc.). -wmdt: set the window manager or desktop to spare x11vnc from guessing. -readtimeout: set libvncserver's read timeout parameter, useful on very slow links that take more than 20secs to paint the whole screen. -nopw: If you use x11vnc without a password it now prints out a scary warning message. Use -nopw to disable the warning. plugged X event leaks; periodically purge any remaining buildup.

No more ugly black fuzz around translucent cursors. Tuning parameters -alpha* if it is still not right. Added mechanisms to handle XFIXES cursors with transparency exactly (i.e. blend in the background). Works by default under -nocursorshape updates, and also works under limited circumstances for cursorshape updates if the VNC viewer is patched (TightVNC viewer patch provided). -solid: to improve performance switch the background to a solid color when clients are connected. Works on GNOME, KDE, CDE, and classic X. -input: allows fine-tuning the type of allowed user input (Keystroke, Mouse-motion, Button-click). Useful for certain applications of x11vnc, e.g. demos. Also per-client settings via -R input:xyz.. -users: enables switching to different users if started as root. Please read the description for details. -gui ez: less daunting GUI with fewer options via '-gui ez' or "Misc -> simple-gui" once started. miscellaneous new features and changes: -nap is now the default, use -nonap to disable. -snapfb: snapshot h/w fb to RAM periodically, not clear how useful... -timeout n: for use in certain applications, exit if no client connects after n seconds. -oa and -logappend for appending to logfiles. -opts will just show the options w/o the long -help descriptions. if you forget to set -display, it will beep and try :0 after a bit.

Requires libXfixes. For approximate cursor shapes also see: -cursor (none|arrow|X|some|most) -remote/-R: remote-control support: nearly every setting can be changed dynamically without restarting x11vnc. For example, "x11vnc -R shared", and "x11vnc -R scale:3/4" will connect to a running x11vnc server to make it shared and re-scaled, respectively. -gui: launches a simple tcl/tk GUI based on the remote control function. Requires the tcl/tk "wish" program. -overlay: support for overlay/multi-depth (e.g. 24+8) visuals on Solaris (SUN_OVL extension) and IRIX. -xrandr: support for the XRANDR (X Resize, Rotate and Reflection) extension: if the screen changes size or rotates x11vnc creates a new framebuffer to match it. Useful to have a VNC Viewer that supports NewFBSize extension. (also -padgeom) -pointer_mode: Experimental pointer input handling schemes, e.g.: "-pointer_mode 3" (similar to -nodragging) man page x11vnc.1 and README files created. miscellaneous new features and changes: -sb: set screen blank idle timeout -nocursorshape: disable cursor shape VNC extension. RFB_MODE = "accept" or "gone" passed to -accept/-gone commands. -vncconnect is now the default. -norepeat is now the default. "-id pick" to pick a window via xwininfo for the -id option. -sid option: like -id but crops root window instead. Related to remote-control: -query, -noremote, -sync, -deny_all, -safer, -unsafe.

While 0.9.13 was the last release by the original author Karl Runge, 0.9.14 was the first community-based release here on GitHub. This repo represents the x11vnc codebase that once resided in the LibVNCServer repo. It was split off LibVNCServer and moved here with https://github.com/LibVNC/libvncserver/commit/498d222976975f53dea885cfe43ef0f805abd412. Copyright (C) 2002-2010 Karl J. Runge All rights reserved. # x11vnc: a VNC server for real X displays x11vnc allows one to view remotely and interact with real X displays (i.e. a display corresponding to a physical monitor, keyboard, and mouse) with any VNC viewer. In this way it plays the role for Unix/X11 that WinVNC plays for Windows. It has built-in SSL/TLS encryption and 2048 bit RSA authentication, including VeNCrypt support; UNIX account and password login support; server-side scaling; single port HTTPS/HTTP+VNC; Zeroconf service advertising; and TightVNC and UltraVNC file-transfer. It has also been extended to work with non-X devices: natively on Mac OS X Aqua/Quartz, webcams and TV tuner capture devices, and embedded Linux systems such as Qtopia Core. Full IPv6 support is provided. More features are described here. It also provides an encrypted Terminal Services mode (-create, -svc, or -xdmsvc options) based on Unix usernames and Unix passwords where the user does not need to memorize his VNC display/port number. Normally a virtual X session (Xvfb) is created for each user, but it also works with X sessions on physical hardware. See the tsvnc terminal services mode of the SSVNC viewer for one way to take advantage of this mode. I wrote x11vnc back in 2002 because x0rfbserver was basically impossible to build on Solaris and had poor performance. The primary x0rfbserver build problems centered around esoteric C++ toolkits. x11vnc is written in plain C and needs only standard libraries and so should work on nearly all Unixes, even very old ones. I also created enhancements to improve the interactive response, added many features, and etc. This page including the FAQ contains much information [*]; solutions to many problems; and interesting applications, but nevertheless please feel free to contact me if you have problems or questions (and if I save you time or expense by giving you some of my time, please consider a PayPal Donation.) Do check the FAQ and this page first; I realize the pages are massive, but you can often use your browser's find-in-page search action using a keyword to find the answer to your problem or question. SSVNC: An x11vnc side-project provides an Enhanced TightVNC Viewer package (SSVNC) for Unix, Windows, and Mac OS X with automatic SSL and/or SSH tunnelling support, SSL Certificate creation, Saved connection profiles, Zeroconf, VeNCrypt, and built-in Proxy support. Added features for the TightVNC Unix viewer: NewFBSize, ZRLE encoding, Viewer-side Scaling, cursor alphablending, low color modes, and enhanced popup menu; UltraVNC extensions support for: File Transfer, Text Chat, Single Window, Server Input, and 1/n Scaling extensions, and UltraVNC DSM encryption. The SSVNC bundle could be placed on, say, a USB memory stick for SSL/SSH VNC viewing from nearly any networked computer. # Announcements Important: If you created any permanent SSL certificates (e.g. via "x11vnc -ssl SAVE ...") on a Debian or Ubuntu system from Sept. 2006 through May 2008, then those keys are likely extremely weak and can be easily cracked. The certificate files should be deleted and recreated on a non-Debian system or an updated one. See http://www.debian.org/security/2008/dsa-1571 for details. The same applies to SSH keys (not used by x11vnc directly, but many people use SSH tunnels for VNC access.) # News See [NEWS](NEWS) # Frequently Asked Questions (FAQs) See [FAQ.md](doc/FAQ.md) # Background VNC (Virtual Network Computing) is a very useful network graphics protocol (applications running on one computer but displaying their windows on another) in the spirit of X, however, unlike X, the viewing-end is very simple and maintains no state. It is a remote framebuffer (RFB) protocol. Some VNC links: * http://www.realvnc.com * http://www.tightvnc.com * http://www.ultravnc.com/ * http://www.testplant.com/products/vine_server/OS_X For Unix, the traditional VNC implementation includes a "virtual" X11 server Xvnc (usually launched via the vncserver command) that is not associated with a physical display, but provides a "fake" one X11 clients (xterm, firefox, etc.) can attach to. A remote user then connects to Xvnc via the VNC client vncviewer from anywhere on the network to view and interact with the whole virtual X11 desktop. The VNC protocol is in most cases better suited for remote connections with low bandwidth and high latency than is the X11 protocol because it involves far fewer "roundtrips" (an exception is the cached pixmap data on the viewing-end provided by X.) Also, with no state maintained the viewing-end can crash, be rebooted, or relocated and the applications and desktop continue running. Not so with X11. So the standard Xvnc/vncserver program is very useful, I use it for things like: * Desktop conferencing with other users (e.g. code reviews.) * Long running apps/tasks I want to be able to view from many places (e.g. from home and work.) * Motif, GNOME, and similar applications that would yield very poor performance over a high latency link. However, sometimes one wants to connect to a real X11 display (i.e. one attached to a physical monitor, keyboard, and mouse: a Workstation or a SunRay session) from far away. Maybe you want to close down an application cleanly rather than using kill, or want to work a bit in an already running application, or would like to help a distant colleague solve a problem with their desktop, or would just like to work out on the deck for a while. This is where x11vnc is useful. # How to use x11vnc In this basic example let's assume the remote machine with the X display you wish to view is "far-away.east:0" and the workstation you are presently working at is "sitting-here.west". Step 0. Download x11vnc (see below) and have it available to run on far-away.east (on some linux distros it is as easy as "apt-get install x11vnc", "emerge x11vnc", etc.) Similarly, have a VNC viewer (e.g. vncviewer) ready to run on sitting-here.west. We recommend TightVNC Viewers (see also our SSVNC viewer.) Step 1. By some means log in to far-away.east and get a command shell running there. You can use ssh, or even rlogin, telnet, or any other method to do this. We do this because the x11vnc process needs to be run on the same machine the X server process is running on (otherwise things would be extremely slow.) Step 2. In that far-away.east shell (with command prompt "far-away>" in this example) run x11vnc directed at the far-away.east X session display: ``` far-away> x11vnc -display :0 ``` You could have also set the environment variable DISPLAY=:0 instead of using "-display :0". This step attaches x11vnc to the far-away.east:0 X display (i.e. no viewer clients yet.) Common Gotcha: To get X11 permissions right, you may also need to set the XAUTHORITY environment variable (or use the -auth option) to point to the correct MIT-MAGIC-COOKIE file (e.g. /home/joe/.Xauthority.) If x11vnc does not have the authority to connect to the display it exits immediately. More on how to fix this below. If you suspect an X11 permissions problem do this simple test: while sitting at the physical X display open a terminal window (gnome-terminal, xterm, etc.) You should be able to run x11vnc successfully in that terminal without any need for command line options. If that works OK then you know X11 permissions are the only thing preventing it from working when you try to start x11vnc via a remote shell. Then fix this with the tips below. Note as of Feb/2007 you can also try the -find option instead of "-display ..." and see if that finds your display and Xauthority. Note as of Dec/2009 the -findauth and "-auth guess" options may be helpful as well. (End of Common Gotcha) When x11vnc starts up there will then be much chatter printed out (use "-q" to quiet it), until it finally says something like: ``` . . 13/05/2004 14:59:54 Autoprobing selected port 5900 13/05/2004 14:59:54 screen setup finished. 13/05/2004 14:59:54 13/05/2004 14:59:54 The VNC desktop is far-away:0 PORT=5900 ``` which means all is OK, and we are ready for the final step. Step 3. At the place where you are sitting (sitting-here.west in this example) you now want to run a VNC viewer program. There are VNC viewers for Unix, Windows, MacOS, Java-enabled web browsers, and even for PDA's like the Palm Pilot and Cell Phones! You can use any of them to connect to x11vnc (see the above VNC links under "Background:" on how to obtain a viewer for your platform or see this FAQ. For Solaris, vncviewer is available in the Companion CD package SFWvnc.) In this example we'll use the Unix vncviewer program on sitting-here by typing the following command in a second terminal window: ``` sitting-here> vncviewer far-away.east:0 ``` That should pop up a viewer window on sitting-here.west showing and allowing interaction with the far-away.east:0 X11 desktop. Pretty nifty! When finished, exit the viewer: the remote x11vnc process will shutdown automatically (or you can use the -forever option to have it wait for additional viewer connections.) Common Gotcha: Nowadays there will likely be a host-level firewall on the x11vnc side that is blocking remote access to the VNC port (e.g. 5900.) You will either have to open up that port (or a range of ports) in your firewall administration tool, or try the SSH tunnelling method below (even still the firewall must allow in the SSH port, 22.) Shortcut: Of course if you left x11vnc running on far-away.east:0 in a terminal window with the -forever option or as a service, you'd only have to do Step 3 as you moved around. Be sure to use a VNC Password or other measures if you do that. Super Shortcut: Here is a potentially very easy way to get all of it working. * Have x11vnc (0.9.3 or later) available to run on the remote host (i.e. in $PATH.) * Download and unpack a SSVNC bundle (1.0.19 or later, e.g. ssvnc_no_windows-1.0.28.tar.gz) on the Viewer-side machine. * Start the SSVNC Terminal Services mode GUI: ./ssvnc/bin/tsvnc * Enter your remote username@hostname (e.g. fred@far-away.east) in the "VNC Terminal Server" entry. * Click "Connect". That will do an SSH to username@hostname and start up x11vnc and then connect a VNC Viewer through the SSH encrypted tunnel. There are a number of things assumed here, first that you are able to SSH into the remote host; i.e. that you have a Unix account there and the SSH server is running. On Unix and MacOS X it is assumed that the ssh client command is available on the local machine (on Windows a plink binary is included in the SSVNC bundle.) Finally, it is assumed that you are already logged into an X session on the remote machine, e.g. your workstation (otherwise, a virtual X server, e.g. Xvfb, will be started for you.) In some cases the remote SSH server will not run commands with the same $PATH that you normally have in your shell there. In this case click on Options -> Advanced -> X11VNC Options, and type in the location of the x11vnc binary under "Full Path". (End of Super Shortcut) Desktop Sharing: The above more or less assumed nobody was sitting at the workstation display "far-away.east:0". This is often the case: a user wants to access her workstation remotely. Another usage pattern has the user sitting at "far-away.east:0" and invites one or more other people to view and interact with his desktop. Perhaps the user gives a demo or presentation this way (using the telephone for vocal communication.) A "Remote Help Desk" mode would be similar: a technician connects remotely to the user's desktop to interactively solve a problem the user is having. For these cases it should be obvious how it is done. The above steps will work, but more easily the user sitting at far-away.east:0 simply starts up x11vnc from a terminal window, after which the guests would start their VNC viewers. For this usage mode the "-connect host1,host2" option may be of use to automatically connect to the vncviewers in "-listen" mode on the list of hosts. ## Tunnelling x11vnc via SSH The above example had no security or privacy at all. When logging into remote machines (certainly when going over the internet) it is best to use ssh, or use a VPN (for a VPN, Virtual Private Network, the above example should be pretty safe.) For x11vnc one can tunnel the VNC protocol through an encrypted ssh channel. It would look something like running the following commands: ``` sitting-here> ssh -t -L 5900:localhost:5900 far-away.east 'x11vnc -localhost -display :0' ``` (you will likely have to provide passwords/passphrases to login from sitting-here into your far-away.east Unix account; we assume you have a login account on far-away.east and it is running the SSH server) And then in another terminal window on sitting-here run the command: ``` sitting-here> vncviewer -encodings "copyrect tight zrle hextile" localhost:0 ``` Note: The -encodings option is very important: vncviewer will often default to "raw" encoding if it thinks the connection is to the local machine, and so vncviewer gets tricked this way by the ssh redirection. "raw" encoding will be extremely slow over a networked link, so you need to force the issue with -encodings "copyrect tight ...". Nowadays, not all viewers use the -encodings option, try "-PreferredEncoding=ZRLE" (although the newer viewers seem to autodetect well when to use raw or not.) Note that "x11vnc -localhost ..." limits incoming vncviewer connections to only those from the same machine. This is very natural for ssh tunnelling (the redirection appears to come from the same machine.) Use of a VNC password is also strongly recommended. Note also the -t we used above (force allocate pseudoterminal), it actually seems to improve interactive typing response via VNC! You may want to add the -C option to ssh to enable compression. The VNC compression is not perfect, and so this may help a bit. However, over a fast LAN you probably don't want to enable SSH compression because it can slow things down. Try both and see which is faster. If your username is different on the remote machine use something like: "fred@far-away.east" in the above ssh command line. Some VNC viewers will do the ssh tunnelling for you automatically, the TightVNC Unix vncviewer does this when the "-via far-away.east" option is supplied to it (this requires x11vnc to be already running on far-away.east or having it started by inetd(8).) See the 3rd script example below for more info. SSVNC: You may also want to look at the Enhanced TightVNC Viewer (ssvnc) bundles because they contain scripts and GUIs to automatically set up SSH tunnels (e.g. the GUI, "ssvnc", does it automatically and so does this command: "ssvnc_cmd -ssh user@far-away.east:0") and can even start up x11vnc as well. The Terminal Services mode of SSVNC is perhaps the easiest way to use x11vnc. You just need to have x11vnc available in $PATH on the remote side (and can SSH to the host), and then on the viewer-side you type something like: ``` tsvnc fred@far-away.east ``` everything else is done automatically for you. Normally this will start a virtual Terminal Services X session (RAM-only), but if you already have a real X session up on the physical hardware it will find that one for you. Gateways: If the machine you SSH into is not the same machine with the X display you wish to view (e.g. your company provides incoming SSH access to a gateway machine), then you need to change the above to, e.g.: "-L 5900:OtherHost:5900": ``` sitting-here> ssh -t -L 5900:OtherHost:5900 gateway.east ``` Where gateway.east is the internet hostname (or IP) of the gateway machine (SSH server.) 'OtherHost' might be, e.g., freds-pc or 192.168.2.33 (it is OK for these to be private hostnames or private IP addresses, the host in -L is relative to the remote server side.) Once logged in, you'll need to do a second login (ssh, rsh, etc.) to the workstation machine 'OtherHost' and then start up x11vnc on it (if it isn't already running.) (The "-connect gateway:59xx" option may be another alternative here with the viewer already in -listen mode.) For an automatic way to use a gateway and have all the network traffic encrypted (including inside the firewall) see Chaining SSH's. These gateway access modes also can be done automatically for you via the "Proxy/Gateway" setting in SSVNC (including the Chaining SSH's case, "Double Proxy".) ## Chaining SSH's Note that for use of a ssh gateway and -L redirection to an internal host (e.g. "-L 5900:otherhost:5900") the VNC traffic inside the firewall is not encrypted and you have to manually log into otherhost to start x11vnc. Kyle Amon shows a method where you chain two ssh's together that encrypts all network traffic and also automatically starts up x11vnc on the internal workstation: ``` #!/bin/sh # gateway="example.com" # or "user@example.com" host="labyrinth" # or "user@hostname" user="kyle" # Need to sleep long enough for all of the passwords and x11vnc to start up. # The /dev/null) & # Chain the vnc connection thru 2 ssh's, and connect x11vnc to user's display: # exec /usr/bin/ssh -t -L 5900:localhost:5900 $gateway \ /usr/bin/ssh -t -L 5900:localhost:5900 $host \ sudo /usr/bin/x11vnc -localhost -auth /home/$user/.Xauthority \ -rfbauth .vnc/passwd -display :0 ``` Also note the use of sudo(1) to switch to root so that the different user's .Xauthority file can be accessed. See the visudo(8) manpage for details on how to set this up (remove the sudo if you do not want to do this). One can also chain together ssh's for reverse connections with vncviewers using the -listen option. For this case -R would replace the -L (and 5500 the 5900, see the #2 example script above). If the gateway machine's sshd is configured with GatewayPorts=no (the default) then the double chaining of "ssh -R ..." will be required for reverse connections to work. ## Firewalls/Routers A lot of people have inexpensive devices for home or office that act as a Firewall and Router to the machines inside on a private LAN. One can usually configure the Firewall/Router from inside the LAN via a web browser. Often having a Firewall/Router sitting between the vncviewer and x11vnc will make it impossible for the viewer to connect to x11vnc. One thing that can be done is to redirect a port on the Firewall/Router to, say, the SSH port (22) on an inside machine (how to do this depends on your particular Firewall/Router, often the router config URL is http://192.168.100.1 See www.portforward.com for more info.) This way you reach these computers from anywhere on the Internet and use x11vnc to view X sessions running on them. Suppose you configured the Firewall/Router to redirect these ports to two internal machines: ``` Port 12300 -> 192.168.1.3, Port 22 (SSH) Port 12301 -> 192.168.1.4, Port 22 (SSH) (where 192.168.1.3 is "jills-pc" and 192.168.1.4 is "freds-pc".) Then the ssh's would look something like: sitting-here> ssh -t -p 12300 -L 5900:localhost:5900 jill@far-away.east 'x11v nc -localhost -display :0' sitting-here> ssh -t -p 12301 -L 5900:localhost:5900 fred@far-away.east 'x11v nc -localhost -display :0' ``` Where far-away.east means the hostname (or IP) that the Router/Firewall is using (for home setups this is usually the IP gotten from your ISP via DHCP, the site http://www.whatismyip.com/ is a convenient way to determine what it is.) It is a good idea to add some obscurity to accessing your system via SSH by using some high random port (e.g. 12300 in the above example.) If you can't remember it, or are otherwise not worried about port scanners detecting the presence of your SSH server and there is just one internal PC involved you could map 22: ``` Port 22 -> 192.168.1.3, Port 22 (SSH) ``` Again, this SSH gateway access can be done automatically for you via the "Proxy/Gateway" setting in SSVNC. And under the "Remote SSH Command" setting you can enter the x11vnc -localhost -display :0. Host-Level-Firewalls: even with the hardware Firewall/Router problem solved via a port redirection, most PC systems have their own Host level "firewalls" enabled to protect users from themselves. I.e. the system itself blocks all incoming connections. So you will need to see what is needed to configure it to allow in the port (e.g. 22) that you desire. E.g. Yast, Firestarter, iptables(1), etc.. VNC Ports and Firewalls: The above discussion was for configuring the Firewall/Router to let in port 22 (SSH), but the same thing can be done for the default VNC port 5900: ``` Port 5900 -> 192.168.1.3, Port 5900 (VNC) Port 5901 -> 192.168.1.4, Port 5900 (VNC) ``` (where 192.168.1.3 is "jills-pc" and 192.168.1.4 is "freds-pc".) This could be used for normal, unencrypted connections and also for SSL encrypted ones. The VNC displays to enter in the VNC viewer would be, say, "far-away.east:0" to reach jills-pc and "far-away.east:1" to reach freds-pc. We assume above that x11vnc is using port 5900 (and any Host-Level-firewalls on jills-pc has been configured to let that port in.) Use the "-rfbport" option to tell which port x11vnc should listen on. For a home system one likely does not have a hostname and would have to use the IP address, say, "24.56.78.93:0". E.g.: ``` vncviewer 24.56.78.93:0 ``` You may want to choose a more obscure port on the router side, e.g. 5944, to avoid a lot of port scans finding your VNC server. For 5944 you would tell the viewer to use: ``` vncviewer 24.56.78.93:44 ``` The IP address would need to be communicated to the person running the VNC Viewer. The site http://www.whatismyip.com/ can help here. Scripts to automate ssh tunneling: As discussed below, there may be some problems with port 5900 being available. If that happens, the above port and display numbers may change a bit (e.g. -> 5901 and :1). However, if you "know" port 5900 will be free on the local and remote machines, you can easily automate the above two steps by using the x11vnc option -bg (forks into background after connection to the display is set up) or using the -f option of ssh. Some example scripts are shown below. Feel free to try the ssh -C to enable its compression and see if that speeds things up noticeably. 1. A simple example script, assuming no problems with port 5900 being taken on the local or remote sides, looks like: ``` #!/bin/sh # usage: x11vnc_ssh : # e.g.: x11vnc_ssh snoopy.peanuts.com:0 # (user@host:N also works) host=`echo $1 | awk -F: '{print $1}'` disp=`echo $1 | awk -F: '{print $2}'` if [ "x$disp" = "x" ]; then disp=0; fi cmd="x11vnc -display :$disp -localhost -rfbauth .vnc/passwd" enc="copyrect tight zrle hextile zlib corre rre raw" ssh -f -t -L 5900:localhost:5900 $host "$cmd" for i in 1 2 3 do sleep 2 if vncviewer -encodings "$enc" :0; then break; fi done ``` See also rx11vnc.pl below. 2. Another method is to start the VNC viewer in listen mode "vncviewer -listen" and have x11vnc initiate a reverse connection using the -connect option: ``` #!/bin/sh # usage: x11vnc_ssh : # e.g.: x11vnc_ssh snoopy.peanuts.com:0 # (user@host:N also works) host=`echo $1 | awk -F: '{print $1}'` disp=`echo $1 | awk -F: '{print $2}'` if [ "x$disp" = "x" ]; then disp=0; fi cmd="x11vnc -display :$disp -localhost -connect localhost" # <== note new option enc="copyrect tight zrle hextile zlib corre rre raw" vncviewer -encodings "$enc" -listen & pid=$! ssh -t -R 5500:localhost:5500 $host "$cmd" kill $pid ``` Note the use of the ssh option "-R" instead of "-L" to set up a remote port redirection. 3. A third way is specific to the TightVNC vncviewer special option -via for gateways. The only tricky part is we need to start up x11vnc and give it some time (5 seconds in this example) to start listening for connections (so we cannot use the TightVNC default setting for VNC_VIA_CMD): ``` #!/bin/sh # usage: x11vnc_ssh : # e.g.: x11vnc_ssh snoopy.peanuts.com:0 host=`echo $1 | awk -F: '{print $1}'` disp=`echo $1 | awk -F: '{print $2}'` if [ "x$disp" = "x" ]; then disp=0; fi VNC_VIA_CMD="ssh -f -t -L %L:%H:%R %G x11vnc -localhost -rfbport 5900 -display :$disp; sleep 5" export VNC_VIA_CMD vncviewer -via $host localhost:0 # must be TightVNC vncviewer. ``` Of course if you already have the x11vnc running waiting for connections (or have it started out of inetd(8)), you can simply use the TightVNC "vncviewer -via gateway host:port" in its default mode to provide secure ssh tunnelling. VNC password file: Also note in the #1. example script that the option "-rfbauth .vnc/passwd" provides additional protection by requiring a VNC password for every VNC viewer that connects. The vncpasswd or storepasswd programs, or the x11vnc -storepasswd option can be used to create the password file. x11vnc also has the slightly less secure -passwdfile and "-passwd XXXXX" options to specify passwords. Very Important: It is up to YOU to tell x11vnc to use password protection (-rfbauth or -passwdfile), it will NOT do it for you automatically or force you to (use -usepw if you want to be forced to.) The same goes for encrypting the channel between the viewer and x11vnc: it is up to you to use ssh, stunnel, -ssl mode, a VPN, etc. (use the Enhanced TightVNC Viewer (SSVNC) GUI if you want to be forced to use SSL or SSH.) For additional safety, also look into the -allow and -localhost options and building x11vnc with tcp_wrappers support to limit host access. ## Tunnelling x11vnc via SSL/TLS One can also encrypt the VNC traffic using an SSL/TLS tunnel such as stunnel.mirt.net (also stunnel.org) or using the built-in (Mar/2006) -ssl openssl mode. A SSL-enabled Java applet VNC Viewer is also provided in the x11vnc package (and https can be used to download it.) Although not as ubiquitous as ssh, SSL tunnelling still provides a useful alternative. See this FAQ on -ssl and -stunnel modes for details and examples. The Enhanced TightVNC Viewer (SSVNC) bundles contain some convenient utilities to automatically set up an SSL tunnel from the viewer-side (i.e. to connect to "x11vnc -ssl ...".) And many other enhancements too. # Downloading x11vnc x11vnc is a contributed program to the LibVNCServer project at SourceForge.net. I use libvncserver for all of the VNC aspects; I couldn't have done without it. The full source code may be found and downloaded (either file-release tarball or GIT tree) from the above link. As of Sep 2010, the x11vnc-0.9.12.tar.gz source package is released (recommended download). The x11vnc 0.9.12 release notes. The x11vnc package is the subset of the libvncserver package needed to build the x11vnc program. Also, you can get a copy of my latest, bleeding edge x11vnc-0.9.13-dev.tar.gz tarball to build the most up to date one. Precompiled Binaries/Packages: See the FAQ below for information about where you might obtain a precompiled x11vnc binary from 3rd parties and some ones I create. VNC Viewers: To obtain VNC viewers for the viewing side (Windows, Mac OS, or Unix) try these links: * http://www.tightvnc.com/download.html * http://www.realvnc.com/download-free.html * http://sourceforge.net/projects/cotvnc/ * http://www.ultravnc.com/ * Our Enhanced TightVNC Viewer (SSVNC)[ssvnc.gif] More tools: Here is a ssh/rsh wrapper script rx11vnc that attempts to automatically do the above Steps 1-3 for you (provided you have ssh/rsh login permission on the machine x11vnc is to be run on.) The above example would be: "rx11vnc far-away.east:0" typed into a shell on sitting-here.west. Also included is an experimental script rx11vnc.pl that attempts to tunnel the vnc traffic through an ssh port redirection (and does not assume port 5900 is free.) Have a look at them to see what they do and customize as needed: * rx11vnc wrapper script * rx11vnc.pl wrapper script to tunnel traffic thru ssh # Building x11vnc Make sure you have all the needed build/compile/development packages installed. On a Debian-based distro you can simply do ``` sudo apt-get build-dep x11vnc ``` to install most of them. To generate the build system, do a ``` autoreconf -fiv ``` After that, it's the usual ``` ./configure make ``` You might want to take a look at the dfferent configure options provided by `configure --help` to build without X11 or adapt the build to your needs in other ways. ## Building on Solaris, FreeBSD, etc Depending on your version of Solaris or other Unix OS the jpeg and/or zlib libraries may be in non-standard places (e.g. /usr/local, /usr/sfw, /opt/sfw, etc.) Note: If configure cannot find these two libraries then TightVNC and ZRLE encoding support will be disabled, and you don't want that!!! The TightVNC encoding gives very good compression and performance, it even makes a noticeable difference over a fast LAN. Shortcuts: On Solaris 10 you can pick up almost everything just by insuring that your PATH has /usr/sfw/bin (for gcc) and /usr/ccs/bin (for other build tools), e.g.: ``` env PATH=/usr/sfw/bin:/usr/ccs/bin:$PATH sh -c './configure; make' ``` (The only thing this misses is /usr/X11/lib/libXrandr.so.2, which is for the little used -xrandr option, see the script below to pick it up as well.) libjpeg is included in Solaris 9 and later (/usr/sfw/include and /usr/sfw/lib), and zlib in Solaris 8 and later (/usr/include and /usr/lib.) So on Solaris 9 you can pick up everything with something like this: ``` env PATH=/usr/local/bin:/usr/ccs/bin:$PATH sh -c './configure --with-jpeg=/usr/sfw; make' ``` assuming your gcc is in /usr/local/bin and x11vnc 0.7.1 or later. These are getting pretty long, see those assignments split up in the build script below. If your system does not have these libraries at all you can get the source for the libraries to build them: libjpeg is available at ftp://ftp.uu.net/graphics/jpeg/ and zlib at http://www.gzip.org/zlib/. See also http://www.sunfreeware.com/ for Solaris binary packages of these libraries as well as for gcc. Normally they will install into /usr/local but you can install them anywhere with the --prefix=/path/to/anywhere, etc. Here is a build script that indicates one way to pass the library locations information to the libvncserver configuration via the CPPFLAGS and LDFLAGS environment variables. ``` #!/bin/sh # Build script for Solaris, etc, with gcc, libjpeg and libz in # non-standard locations. # set to get your gcc, etc: # PATH=/path/to/gcc/bin:/usr/ccs/bin:/usr/sfw/bin:$PATH JPEG=/path/to/jpeg # set to maybe "/usr/local", "/usr/sfw", or "/opt/sfw" ZLIB=/path/to/zlib # set to maybe "/usr/local", "/usr/sfw", or "/opt/sfw" # Below we assume headers in $JPEG/include and $ZLIB/include and the # shared libraries are in $JPEG/lib and $ZLIB/lib. If your situation # is different change the locations in the two lines below. # CPPFLAGS="-I $JPEG/include -I $ZLIB/include" LDFLAGS="-L$JPEG/lib -R $JPEG/lib -L$ZLIB/lib -R $ZLIB/lib" # These two lines may not be needed on more recent Solaris releases: # CPPFLAGS="$CPPFLAGS -I /usr/openwin/include" LDFLAGS="$LDFLAGS -L/usr/openwin/lib -R /usr/openwin/lib" # These are for libXrandr.so on Solaris 10: # CPPFLAGS="$CPPFLAGS -I /usr/X11/include" LDFLAGS="$LDFLAGS -L/usr/X11/lib -R /usr/X11/lib" # Everything needs to built with _REENTRANT for thread safe errno: # CPPFLAGS="$CPPFLAGS -D_REENTRANT" export PATH CPPFLAGS LDFLAGS ./configure make ls -l ./x11vnc/x11vnc ``` Then do make install or copy the x11vnc binary to your desired destination. BTW, To run a shell script, just cut-and-paste the above into a file, say "myscript", then modify the "/path/to/..." items to correspond to your system/environment, and then type: "sh myscript" to run it. Note that on Solaris make is /usr/ccs/bin/make, so that is why the above puts /usr/ccs/bin in PATH. Other important build utilities are there too: ld, ar, etc. Also, it is probably a bad idea to have /usr/ucb in your PATH while building. Starting with the 0.7.1 x11vnc release the "configure --with-jpeg=DIR --with-zlib=DIR" options are handy if you want to avoid making a script. If you need to link OpenSSL libssl.a on Solaris see this method. If you need to build on Solaris 2.5.1 or earlier or other older Unix OS's, see this workaround FAQ. ## Building on FreeBSD, OpenBSD, ... The jpeg libraries seem to be in /usr/local or /usr/pkg on these OS's. You won't need the openwin stuff in the above script (but you may need /usr/X11R6/....) Also starting with the 0.7.1 x11vnc release, this usually works: ``` ./configure --with-jpeg=/usr/local make ``` ## Building on HP-UX For jpeg and zlib you will need to do the same sort of thing as described above for Solaris. You set CPPFLAGS and LDFLAGS to find them (see below for an example.) You do not need to do any of the above /usr/openwin stuff. Also, HP-UX does not seem to support -R, so get rid of the -R items in LDFLAGS. Because of this, at runtime you may need to set LD_LIBRARY_PATH or SHLIB_PATH to indicate the directory paths so the libraries can be found. It is a good idea to have static archives, e.g. libz.a and libjpeg.a for the nonstandard libraries so that they get bolted into the x11vnc binary (and so won't get "lost".) Here is what we recently did to build x11vnc 0.7.2 on HP-UX 11.11 ``` ./configure --with-jpeg=$HOME/hpux/jpeg --with-zlib=$HOME/hpux/zlib make ``` Where we had static archives (libjpeg.a, libz.a) only and header files in the $HOME/hpux/... directories as discussed for the build script. On HP-UX 11.23 and 11.31 we have had problems compiling with gcc. "/usr/include/rpc/auth.h:87: error: field 'syncaddr' has incomplete type". As a workaround for x11vnc 0.9.4 and later set your CPPFLAGS to include: ``` CPPFLAGS="-DIGNORE_GETSPNAM" export CPPFLAGS ``` This disables a very rare usage mode for -unixpw_nis by not trying getspnam(3). Using HP-UX's C compiler on 11.23 and 11.31 we have some severe compiler errors that have not been worked around yet. If you need to do this, contact me and I will give you a drastic recipe that will produce a working binary. ## Building on AIX AIX: one user had to add the "X11.adt" package to AIX 4.3.3 and 5.2 to get build header files like XShm.h, etc. You may also want to make sure that /usr/lpp/X11/include, etc is being picked up by the configure and make. For a recent build on AIX 5.3 we needed to add these CFLAGS to be able to build with gcc: env CFLAGS='-maix64 -Xlinker -bbigtoc' ./configure ... we also built our own libjpeg and libz using -maix64. BTW, one way to run an Xvfb-like virtual X server for testing on AIX is something like "/usr/bin/X11/X -force -vfb -ac :1". ## Building on Mac OS X There is now native Mac OS X support for x11vnc by using the raw framebuffer feature. This mode does not use or need X11 at all. To build you may need to disable X11: ``` ./configure --without-x ... make ``` However, if your system has the Mac OS X build package for X11 apps you will not need to supply the "--without-x" option (in this case the resulting x11vnc would be able to export both the native Mac OS X display and windows displayed in the XDarwin X server.) Be sure to include the ./configure option to find libjpeg on your system. ## OpenSSL Starting with version 0.8.3 x11vnc can now be built with SSL/TLS support. For this to be enabled the libssl.so library needs to be available at build time. So you may need to have additional CPPFLAGS and LDFLAGS items if your libssl.so is in a non-standard place. As of x11vnc 0.9.4 there is also the --with-ssl=DIR configure option. Note that from OpenSSL 1.1.0 on SSLv2 support has been dropped and SSLv3 deactivated at build time per default. This means that unless explicitly enabled, OpenSSL builds only support TLS (any version). Since there is a reason for dropping SSLv3 (heard of POODLE?), most distributions do not enable it for their OpenSSL binary. In summary this means compiling x11vnc against OpenSSL 1.1.0 or newer is no problem, but using encryption will require a viewer with TLS support. On Solaris using static archives libssl.a and libcrypto.a instead of .so shared libraries (e.g. from www.sunfreeware.com), we found we needed to also set LDFLAGS as follows to get the configure to work: ``` env LDFLAGS='-lsocket -ldl' ./configure --with-ssl=/path/to/openssl ... make ``` ## Misc. Build problems We collect here rare build problems some users have reported and the corresponding workarounds. See also the FAQ's on building. --- ENV parameter: One user had a problem where the build script below was failing because his work environment had the ENV variable set to a script that was resetting his PATH so that gcc could no longer be found. Make sure you do not have any ENV or BASH_ENV in your environment doing things like that. Typing "unset ENV", etc. before configuring and building should clear it. --- Bash xpg: One user had his bash shell compiled with --enable-xpg-echo-default that causes some strange behavior with things like echo "\\1 ..." the configure script executes. In particular instead of getting "\1" the non-printable character "^A" is produced, and causes failures at compile time like: ``` ../rfb/rfbconfig.h:9:22: warning: extra tokens at end of #ifndef directive ``` The workaround is to configure like this: ``` env CONFIG_SHELL=/bin/sh /bin/sh ./configure ``` i.e. avoid using the bash with the misbehavior. A bug has been filed against autoconf to guard against this. --- AIX: one user had to add the "X11.adt" package to AIX to get build header files like XShm.h, etc. --- Ubuntu Feisty Fawn 7.04: In May/2007 one user said he needed to add these packages to compile x11vnc on that Linux distro and version: ``` apt-get install build-essential make bin86 libjpeg62-dev libssl-dev libxtst-dev ``` Note that Ubuntu is based on Debian, so perhaps this is the list needed on Debian (testing?) as well. To build in Avahi (mDNS service advertising) support it would appear that libavahi-client-dev is needed as well. --- Exceedingly slow compilation: x11vnc has a couple of files which contain very large "case statements" (over 100 cases) that on some platforms can take a very long time to compile (in extreme cases over an hour). However on 32bit Linux with intel/amd processor and gcc these files usually take less than 10 seconds to compile. For 64bit systems using gcc the problem appears to be much worse. The two files with the large number of cases, remote.c and x11vnc.c, have no real need to be optimized (the code is used only very infrequently). So it is fine to supply "-O0" (disables optimization) to CFLAGS when compiling them. However, it is tricky with autoconf/automake to do this (especially since both the compiler and make versions have a big effect). So if the compile times are getting too long for you for these two files you will need to manually change some things. First, run configure and when it has finished, edit the generated file x11vnc/Makefile and put these lines at the very top: ``` x11vnc-x11vnc.o : CFLAGS += -O0 x11vnc-remote.o : CFLAGS += -O0 ``` Those lines assume gnu make (gmake) is being used. If you are using another make, say Solaris make, insert these instead: ``` x11vnc-x11vnc.o := CFLAGS += -O0 x11vnc-remote.o := CFLAGS += -O0 ``` You could write a build shell script that modified the Makefile this way before running make. The "-O0" (note it is "capital Oh" followed by "zero") assumes the gcc compiler. If you are using a different compiler you will need to find the command line option to disable optimization, or otherwise have the lines set CFLAGS to the empty string. --- Broken Thread Local Storage on SuSE 9.2: Starting with x11vnc 0.9.8 the bundled libvncserver uses the __thread keyword to make some of the encodings (i.e. tight) thread safe (multiple VNC clients can be using tight at the same time in x11vnc -threads mode.) Evidently on the old SuSE 9.2 system the compiler does not support the thread local storage properly. Here is an example build failure: ``` tight.c:1126: error: unrecognizable insn: (insn:HI 11 10 13 0 (nil) (set (reg/f:SI 59) (const:SI (plus:SI (symbol_ref:SI ("%lpalette")) (const_int 2048 [0x800])))) -1 (nil) (expr_list:REG_EQUAL (const:SI (plus:SI (symbol_ref:SI ("%lpalette")) (const_int 2048 [0x800]))) (nil))) tight.c:1126: internal compiler error: in extract_insn, at recog.c:2175 Please submit a full bug report, with preprocessed source if appropriate. See URL:http://www.suse.de/feedback for instructions. ``` The workaround is to disable thread local storage at configure time like this: ``` env CPPFLAGS="-DTLS=''" ./configure ``` and then build it. # Some Notes ## Both a client and a server It is sometimes confusing to people that x11vnc is both a client and a server at the same time. It is an X client because it connects to the running X server to do the screen polls. Think of it as a rather efficient "screenshot" program running continuously. It is a server in the sense that it is a VNC server that VNC viewers on the network can connect to and view the screen framebuffer it manages. When trying to debug problems, remember to think of both roles. E.g. "how is x11vnc connecting to the X server?", "how is the vncviewer connecting to x11vnc?", "what permits/restricts the connection?". Both links may have reachability, permission, and other issues. ## Network performance Whether you are using Xvnc or x11vnc it is always a good idea to have a solid background color instead of a pretty background image. Each and every re-exposure of the background must be resent over the network: better to have that background be a solid color that compresses very well compared to a photo image. (This is one place where the X protocol has an advantage over the VNC protocol.) I suggest using xsetroot, dtstyle or similar utility to set a solid background while using x11vnc. You can turn the pretty background image back on when you are using the display directly. Update: As of Feb/2005 x11vnc has the -solid [color] option that works on recent GNOME, KDE, and CDE and also on classic X (background image is on the root window.) Update: As of Oct/2007 x11vnc has the -ncache option that does a reasonable job caching the background (and other) pixmap data on the viewer side. I also find the TightVNC encoding gives the best response for my usage (Unix <-> Unix over cable modem.) One needs a tightvnc-aware vncviewer to take advantage of this encoding. ## TCP port issues Notice the lines ``` 18/07/2003 14:36:31 Autoprobing selected port 5900 PORT=5900 ``` in the output. 5900 is the default VNC listening port (just like 6000 is X11's default listening port.) Had port 5900 been taken by some other application, x11vnc would have next tried 5901. That would mean the viewer command above should be changed to vncviewer far-away.east:1. You can force the port with the "-rfbport NNNN" option where NNNN is the desired port number. If that port is already taken, x11vnc will exit immediately. The "-N" option will try to match the VNC display number to the X display. (also see the "SunRay Gotcha" note below) ## Options x11vnc has (far too) many features that may be activated via its command line options. Useful options are, e.g., -scale to do server-side scaling, and -rfbauth passwd-file to use VNC password protection (the vncpasswd or storepasswd programs, or the x11vnc -storepasswd option can be used to create the password file.) ## Algorithm How does x11vnc do it? Rather brute-forcedly: it continuously polls the X11 framebuffer for changes using XShmGetImage(). When changes are discovered, it instructs libvncserver which rectangular regions of the framebuffer have changed, and libvncserver compresses the changes and sends them off to any connected VNC viewers. A number of applications do similar things, such as x0rfbserver, krfb, x0vncserver, vino. x11vnc uses a 32 x 32 pixel tile model (the desktop is decomposed into roughly 1000 such tiles), where changed tiles are found by pseudo-randomly polling 1 pixel tall horizontal scanlines separated vertically by 32 pixels. This is a surprisingly effective algorithm for finding changed regions. For keyboard and mouse user input the XTEST extension is used to pass the input events to the X server. To detect XBell "beeps" the XKEYBOARD extension is used. If available, the XFIXES extension is used to retrieve the current mouse cursor shape. Also, if available the X DAMAGE extension is used to receive hints from the X server where modified regions on the screen are. This greatly reduces the system load when not much is changing on the screen and also improves how quickly the screen is updated. ## Barbershop mirrors effect What if x11vnc is started up, and vncviewer is then started up on the same machine and displayed on the same display x11vnc is polling? One might "accidentally" do this when first testing out the programs. You get an interesting recursive/feedback effect where vncviewer images keep popping up each one contained in the previous one and slightly shifted a bit by the window manager decorations. There will be an even more interesting effect if -scale is used. Also, if the XKEYBOARD is supported and the XBell "beeps" once, you get an infinite loop of beeps going off. Although all of this is mildly exciting it is not much use: you will normally run and display the viewer on a different machine! # Limitations * Due to the polling nature, some activities (opaque window moves, scrolling), can be pretty choppy/ragged and others (exposures of large areas) slow. Experiment with interacting a bit differently than you normally do to minimize the effects (e.g. do fullpage paging rather than line-by-line scrolling, and move windows in a single, quick motion.) Recent work has provided the -scrollcopyrect and -wireframe speedups using the CopyRect VNC encoding and other things, but they only speed up some activities, not all. * A rate limiting factor for x11vnc performance is that graphics hardware is optimized for writing, not reading (x11vnc reads the video framebuffer for the screen image data.) The difference can be a factor of 10 to 1000, and so it usually takes about 0.5-1 sec to read in the whole video hardware framebuffer (e.g. 5MB for 1280x1024 at depth 24 with a read rate of 5-10MB/sec.) So whenever activity changes most of the screen (e.g. moving or iconifying a large window) there is a delay of 0.5-1 sec while x11vnc reads the changed regions in. A slow framebuffer read rate will often be the performance bottleneck on a fast LAN (whereas on slower links the reduced network bandwidth becomes the bottleneck.) Note: A quick way to get a 2X speedup of this for x11vnc is to switch your X server from depth 24 (32bpp) to depth 16 (16bpp.) You get a 4X speedup going to 8bpp, but the lack of color cells is usually unacceptable. To get a sense of the read and write speeds of your video card, you can run benchmarks like: "x11perf -getimage500", "x11perf -putimage500", "x11perf -shmput500" and for XFree86 displays with direct graphics access the "dga" command (press "b" to run the benchmark and then after a few seconds press "q" to quit.) Even this "dd if=/dev/fb0 of=/dev/null" often gives a good estimate. x11vnc also prints out its estimate: ``` 28/02/2009 11:11:07 Autoprobing TCP port 28/02/2009 11:11:07 Autoprobing selected port 5900 28/02/2009 11:11:08 fb read rate: 10 MB/sec 28/02/2009 11:11:08 screen setup finished. ``` We have seen a few cases where the hardware fb read speed is greater than 65 MB/sec: on high end graphics workstations from SGI and Sun, and also from a Linux user using nvidia proprietary drivers for his nvidia video card. Update 2008: thankfully, these sped up drivers are becoming more common on Linux and *BSD systems and that makes x11vnc run somewhat more quickly. Sometimes they have a read rate of over 400 MB/sec. On XFree86/Xorg it is actually possible to increase the framebuffer read speed considerably (10-100 times) by using the Shadow Framebuffer (a copy of the framebuffer is kept in main memory and this can be read much more quickly.) To do this one puts the line Option "ShadowFB" "true" in the Device section of the /etc/X11/XF86Config or /etc/X11/xorg.conf file. Note that this disables 2D acceleration at the physical display and so that might be unacceptable if one plays games, etc. on the machine's local display. Nevertheless this could be handy in some circumstances, e.g. if the slower speed while sitting at the physical display was acceptable (this seems to be true for most video cards these days.) Unfortunately it does not seem shadowfb can be turned on and off dynamically... Another amusing thing one can do is use Xvfb as the X server, e.g. "xinit $HOME/.xinitrc -- /usr/X11R6/bin/Xvfb :1 -screen 0 1024x768x16" x11vnc can poll Xvfb efficiently via main memory. It's not exactly clear why one would want to do this instead of using vncserver/Xvnc, (perhaps to take advantage of an x11vnc feature, such as framebuffer scaling or built-in SSL encryption), but we mention it because it may be of use for special purpose applications. You may need to use the "-cc 4" option to force Xvfb to use a TrueColor visual instead of DirectColor. See also the description of the -create option that does all of this automatically for you (be sure to install the Xvfb package, e.g. apt-get install xvfb.) Also, a faster and more accurate way is to use the "dummy" Xorg/XFree86 device driver (or our Xdummy wrapper script.) See this FAQ for details. * Somewhat surprisingly, the X11 mouse (cursor) shape is write-only and cannot be queried from the X server. So traditionally in x11vnc the cursor shape stays fixed at an arrow. (see the "-cursor X" and "-cursor some" options, however, for a partial hack for the root window, etc.) However, on Solaris using the SUN_OVL overlay extension, x11vnc can show the correct mouse cursor when the -overlay option is also supplied. A similar thing is done on IRIX as well when -overlay is supplied. More generally, as of Dec/2004 x11vnc supports the new XFIXES extension (in Xorg and Solaris 10) to query the X server for the exact cursor shape, this works pretty well except that cursors with transparency (alpha channel) need to approximated to solid RGB values (some cursors look worse than others.) * Audio from applications is of course not redirected (separate redirectors do exist, e.g. esd, see the FAQ on this below.) The XBell() "beeps" will work if the X server supports the XKEYBOARD extension. (Note that on Solaris XKEYBOARD is disabled by default. Passing +kb to Xsun enables it.) * The scroll detection algorithm for the -scrollcopyrect option can give choppy or bunched up transient output and occasionally painting errors. * Using -threads can expose some bugs/crashes in libvncserver. x11vnc-0.9.17/README.md000077700000000000000000000000001500463450600150652READMEustar00rootroot00000000000000x11vnc-0.9.17/autogen.sh000077500000000000000000000003121500463450600147300ustar00rootroot00000000000000#!/bin/sh srcdir=$(dirname "$0") test -z "$srcdir" && srcdir=.

It says "XOpenDisplay failed (null)" or "Xlib: connection to ":0.0" refused by server Xlib: No protocol specified" and then exits. What do I need to do? For the former error, you need to specify the X display to connect to (it also needs to be on the same machine the x11vnc process is to run on.) Set your DISPLAY environment variable (or use the -display option) to specify it. Nearly always the correct value will be ":0" (in fact, x11vnc will now assume :0 if given no other information.) For the latter error, you need to set up the X11 permissions correctly. To make sure X11 permissions are the problem do this simple test: while sitting at the physical X display open a terminal window (gnome-terminal, xterm, etc.) You should be able to run x11vnc successfully without any need for special steps or command line options in that terminal (i.e. just type "x11vnc".) If that works OK then you know X11 permissions are the only thing preventing it from working when you try to start x11vnc via, say, a remote shell. How to Solve: See the xauth(1), Xsecurity(7), and xhost(1) man pages or this Howto for much info on X11 permissions. For example, you may need to set your XAUTHORITY environment variable (or use the -auth option) to point to the correct MIT-MAGIC-COOKIE file (e.g. /home/joe/.Xauthority or /var/gdm/:0.Xauth or /var/lib/kdm/A:0-crWk72K or /tmp/.gdmzndVlR, etc, etc.), or simply be sure you run x11vnc as the correct user (i.e. the user who is logged into the X session you wish to view.) Note: The MIT cookie file contains the secret key that allows x11vnc to connect to the desired X display. If, say, sshd has set XAUTHORITY to point to a random file it has created for X forwarding that will cause problems. (Under some circumstances even su(1) and telnet(1) can set XAUTHORITY. See also the gdm parameter NeverPlaceCookiesOnNFS that sets XAUTHORITY to a random filename in /tmp for the whole X session.) Running x11vnc as root is often not enough: you need to know where the MIT-MAGIC-COOKIE file for the desired X display is. Example solution: ``` x11vnc -display :0 -auth /var/gdm/:0.Xauth ``` (this is for the display manager gdm and requires root permission to read the gdm cookie file, see this faq for other display manager cookie file names.) Note as of Feb/2007 you can also try the -find option instead of "-display ..." and see if that finds your display and Xauthority. Less safe, but to avoid figuring out where the correct XAUTHORITY file is, if the person sitting at the physical X session types "xhost +localhost" then one should be able to attach x11vnc to the session (from the same machine.) The person could then type "xhost -localhost" after x11vnc has connected to go back to the default permissions. Also, for some situations the "-users lurk=" option may soon be of use (please read the documentation on the -users option.) To test out your X11 permissions from a remote shell, set DISPLAY and possibly XAUTHORITY (see your shell's man page, bash(1), tcsh(1), on how to set environment variables) and type xdpyinfo in the same place you will be typing (or otherwise running) x11vnc. If information is printed out about the X display (screen sizes, supported extensions, color visuals info) that means the X11 permissions are set up properly: xdpyinfo successfully connected to DISPLAY! You could also type xclock and make sure no errors are reported (a clock should appear on the X display, press Ctrl-C to stop it.) If these work, then typing "x11vnc" in the same environment should also work. Important: if you cannot get your X11 permissions so that the xdpyinfo or xclock tests work, x11vnc also will not work (all of these X clients must be allowed to connect to the X server to function properly.) Firewalls: Speaking of permissions, it should go without saying that the host-level firewall will need to be configured to allow connections in on a port. E.g. 5900 (default VNC port) or 22 (default SSH port for tunnelling VNC.) Most systems these days have firewalls turned on by default, so you will actively have to do something to poke a hole in the firewall at the desired port number. See your system administration tool for Firewall settings (Yast, Firestarter, etc.) ### Q-2: I can't get x11vnc and/or libvncserver to compile. Make sure you have gcc (or other C compiler) and all of the required libraries and the corresponding -dev/-devel packages installed. These include Xorg/XFree86, libX11, libjpeg, libz, libssl, ... and don't forget the devs: libjpeg-dev, libssl-dev ... The most common build problem that people encounter is that the necessary X11 libraries are installed on their system however it does not have the corresponding -dev/-devel packages installed. These dev packages include C header files and build-time .so symlink. It is a shame the current trend in distros is to not install the dev package by default when the the library runtime package is installed... (it diminishes the power of open source) As of Nov/2006 here is a list of libraries that x11vnc usually likes to use: ``` libc.so libX11.so libXtst.so libXext.so libXfixes.so libXdamage.so libXinerama.so libXrandr.so libz.so libjpeg.so libpthread.so libssl.so libcrypto.so libcrypt.so ``` although x11vnc will be pretty usable with the subset: libc.so, libX11.so, libXtst.so, libXext.so, libz.so, and libjpeg.so. After running the libvncserver configure, carefully examine the output and the messages in the config.log file looking for missing components. For example, if the configure output looks like: ``` checking how to run the C preprocessor... gcc -E checking for X... no checking for XkbSelectEvents in -lX11... no checking for XineramaQueryScreens in -lXinerama... no checking for XTestFakeKeyEvent in -lXtst... no ``` or even worse: ``` checking for C compiler default output file name... configure: error: C compiler cannot create executables See `config.log' for more details. ``` there is quite a bit wrong with the build environment. Hopefully simply adding -dev packages and/or gcc or make will fix it. For Debian the list seems to be: ``` gcc make libc6-dev libjpeg8-dev (formerly libjpeg62-dev) libx11-dev x11proto-core-dev (formerly x-dev) libxext-dev libxtst-dev libxdamage-dev libxfixes-dev libxrandr-dev libxinerama-dev libxss-dev (formerly xlibs-static-dev) zlib1g-dev libssl-dev libavahi-client-dev linux-libc-dev (only needed for linux console rawfb support) ``` Note that depending on your OS version the above names may have been changed and/or additional packages may be needed. For Redhat the list seems to be: ``` gcc make glibc-devel libjpeg-devel libX11-devel xorg-x11-proto-devel libXdamage-devel libXfixes-devel libXrandr-devel zlib-devel openssl-devel avahi-devel kernel-headers (only needed for linux console rawfb support) ``` For other distros or OS's the package names may not be the same but will look similar. Also, distros tend to rename packages as well so the above list may be out of date. So only use the above lists as hints for the package names that are needed. Have a look at Misc. Build Problems for additional fixes. Note: there is growing trend in Linux and other distros to slice up core X11 software into more and smaller packages. So be prepared for more headaches compiling software... ### Q-3: I just built x11vnc successfully, but when I use it my keystrokes and mouse button clicks are ignored (I am able to move the mouse though.) This is most likely due to you not having a working build environment for the XTEST client library libXtst.so. The library is probably present on your system, but the package installing the build header file is missing. If you were watching carefully while configure was running you would have seen: checking for XTestFakeKeyEvent in -lXtst... no The solution is to add the necessary build environment package (and the library package if that is missing too.) On Debian the build package is libxtst-dev. Other distros/OS's may have it in another package. x11vnc will build without support for this library (e.g. perhaps one wants a view-only x11vnc on a stripped down or embedded system...) And at runtime it will also continue to run even if the X server it connects to does not support XTEST. In both cases it cannot inject keystrokes or button clicks since XTEST is needed for that (it can still move the mouse pointer using the X API XWarpPointer().) You will see a warning message something like this at run time: ``` 20/03/2005 22:33:09 WARNING: XTEST extension not available (either missing from 20/03/2005 22:33:09 display or client library libXtst missing at build time.) 20/03/2005 22:33:09 MOST user input (pointer and keyboard) will be DISCARDED. 20/03/2005 22:33:09 If display does have XTEST, be sure to build x11vnc with 20/03/2005 22:33:09 a working libXtst build environment (e.g. libxtst-dev, 20/03/2005 22:33:09 or other packages.) 20/03/2005 22:33:09 No XTEST extension, switching to -xwarppointer mode for 20/03/2005 22:33:09 pointer motion input. ``` Also, as of Nov/2006 there will be a configure build time warning as well: ``` ... checking for XFixesGetCursorImage in -lXfixes... yes checking for XDamageQueryExtension in -lXdamage... yes configure: WARNING: ========================================================================== A working build environment for the XTEST extension was not found (libXtst). An x11vnc built this way will be only barely usable. You will be able to move the mouse but not click or type. There can also be deadlocks if an application grabs the X server. It is recommended that you install the necessary development packages for XTEST (perhaps it is named something like libxtst-dev) and run configure again. ========================================================================== ``` ### Q-4: Help, I need to run x11vnc on Solaris 2.5.1 (or other old Unix/Linux) and it doesn't compile! We apologize that x11vnc does not build cleanly on older versions of Solaris, Linux, etc.: very few users are on these old releases. We have heard that since Dec/2004 a Solaris 2.6 built x11vnc will run on Solaris Solaris 2.5 and 2.5.1 (since a workaround for XConvertCase is provided.) In any event, here is a workaround for Solaris 2.5.1 (and perhaps earlier and perhaps non-Solaris): First use the environment settings (CPPFLAGS, LDFLAGS, etc.) in the above Solaris build script to run the configure command. That should succeed without failure. Then you have to hand edit the autogenerated rfb/rfbconfig.h file in the source tree, and just before the last #endif at the bottom of that file insert these workaround lines: ``` struct timeval _tmp_usleep_tv; #define usleep(x) \ _tmp_usleep_tv.tv_sec = (x) / 1000000; \ _tmp_usleep_tv.tv_usec = (x) % 1000000; \ select(0, NULL, NULL, NULL, &_tmp_usleep_tv); int gethostname(char *name, int namelen); long random(); int srandom(unsigned int seed); #undef LIBVNCSERVER_HAVE_LIBPTHREAD #define SHUT_RDWR 2 typedef unsigned int in_addr_t; #define snprintf(a, n, args...) sprintf((a), ## args) ``` Then run make with the Solaris build script environment, everything should compile without problems, and the resulting x11vnc binary should work OK. If some non-x11vnc related programs fail (e.g. test programs) and the x11vnc binary is not created try "make -k" to have it keep going. Similar sorts of kludges in rfb/rfbconfig.h can be done on other older OS (Solaris, Linux, ...) releases. Here are some notes for similar steps that need to be done to build on SunOS 4.x Please let us know if you had to use the above workaround (and whether it worked or not.) If there is enough demand we will try to push clean compilations back to earlier Solaris, Linux, etc, releases. ### Q-5: Where can I get a precompiled x11vnc binary for my Operating System? Hopefully the build steps above and FAQ provide enough info for a painless compile for most environments. Please report problems with the x11vnc configure, make, etc. on your system (if your system is known to compile other GNU packages successfully.) There are precompiled x11vnc binaries built by other groups that are available at the following locations: * Slackware: (.tgz) http://www.linuxpackages.net/ * SuSE: (.rpm) http:/software.opensuse.org/ * Gentoo: (info) http://gentoo-wiki.com/ and http://gentoo-portage.com/ * FreeBSD: (.tbz) http://www.freebsd.org/ http://www.freshports.org/net/x11vnc * NetBSD: (src) http://pkgsrc.se/x11/x11vnc * OpenBSD: (.tgz) http://openports.se/ * Arch Linux: (.tgz) http://www.archlinux.org/ * Nokia 770 (.deb) http://mike.saunby.googlepages.com/x11vncfornokia7702 * Sharp Zaurus: http://www.focv.com/ * Debian: (.deb) http://packages.debian.org/x11vnc * Redhat/Fedora: (.rpm) http://packages.sw.be/x11vnc RPMforge http://dag.wieers.com/rpm/packages/x11vnc/ (N.B.: unmaintained after 0.9.3) * Solaris: (pkg) http://www.sunfreeware.com/ If the above binaries don't work and building x11vnc on your OS fails (and all else fails!) you can try one of My Collection of x11vnc Binaries for various OS's and x11vnc releases. As a general note, the x11vnc program is simple enough you don't really need to install a package: the binary will in most cases work as is and from any location (as long as your system libraries are not too old, etc.) So, for Linux distributions that are not one of the above, the x11vnc binary from the above packages has a good chance of working. You can "install" it by just copying the x11vnc binary to the desired directory in your PATH. Tip on extracting files from a Debian package: extract the archive via a command like: "ar x x11vnc_0.6-2_i386.deb" and then you can find the binary in the resulting data.tar.gz tar file. Also, rpm2cpio(1) is useful in extracting files from rpm packages. If you use a standalone binary like this and also want x11vnc to serve up the Java VNC Viewer jar file (either SSL enabled or regular one), then you will need to extract the classes subdirectory from the source tarball and point x11vnc to it via the -httpdir option. E.g.: x11vnc -httpdir /path/to/x11vnc-0.9.9/classes/ssl ... Alternatively, you can also go for a more up-to-date approach and use the very decent noVNC viewer (https://kanaka.github.io/noVNC/) that is purely HTML5 and does not need any plugins at all. ### Q-6: Where can I get a VNC Viewer binary (or source code) for the Operating System I will be viewing from? To obtain VNC viewers for the viewing side (Windows, Mac OS, or Unix) try here: * http://www.tightvnc.com/download.html * http://www.realvnc.com/download-free.html * http://sourceforge.net/projects/cotvnc/ * http://www.ultravnc.com/ * Our Enhanced TightVNC Viewer (SSVNC)[ssvnc.gif] ### Q-7: How can I see all of x11vnc's command line options and documentation on how to use them? Run: x11vnc -opts to list just the option names or run: x11vnc -help for long descriptions about each option. The output is listed here as well. Yes, x11vnc does have a lot of options, doesn't it... ### Q-8: I don't like typing arcane command line options every time I start x11vnc. What can I do? Is there a config file? Or a GUI? You could create a shell script that calls x11vnc with your options: ``` #!/bin/sh # # filename: X11vnc (i.e. not "x11vnc") # It resides in a directory in $PATH. "chmod 755 X11vnc" has been run on it. # x11vnc -wait 50 -localhost -rfbauth $HOME/.vnc/passwd -display :0 $* ``` a similar thing can be done via aliases in your shell (bash, tcsh, csh, etc..) Or as of Jun/2004 you can use the simple $HOME/.x11vncrc config file support. If that file exists, each line is taken as a command line option. E.g. the above would be: ``` # this is a comment in my ~/.x11vncrc file wait 50 # this is a comment to the end of the line. -localhost # note: the leading "-" is optional. rfbauth /home/fred/.vnc/passwd display :0 ``` As of Dec/2004 there is now a simple Tcl/Tk GUI based on the remote-control functionality ("-R") that was added. The /usr/bin/wish program is needed for operation. The gui is not particularly user-friendly, it just provides a point and click mode to set all the many x11vnc parameters and obtain help on them. It is also very useful for testing. See the -gui option for more info. Examples: "x11vnc ... -gui" and "x11vnc ... -gui other:0" in the latter case the gui is displayed on other:0, not the X display x11vnc is polling. There is also a "-gui tray" system tray mode. [tkx11vnc.gif] NOTE: You may need to install the "wish" or "tk" or "tk8.4" package for the gui mode to work (the package name depends on your OS/distro.) The tcl/tk "wish" interpreter is used. In debian (and so ubuntu too) one would run "apt-get install tk" or perhaps "apt-get install tk8.4" ### Q-9: How can I get the GUI to run in the System Tray, or at least be a smaller, simpler icon? As of Jul/2005 the gui can run in a more friendly small icon mode "-gui icon" or in the system tray: "-gui tray". It has balloon status, a simple menu, and a Properities dialog. The full, complicated, gui is only available under "Advanced". Other improvements were added as well. Try "Misc -> simple_gui" for a gui with fewer esoteric menu items. If the gui fails to embed itself in the system tray, do a retry via "Window View -> icon" followed by "Window View -> tray" with the popup menu. For inexperienced users starting up x11vnc and the GUI while sitting at the physical X display (not remotely), using something like "x11vnc -display :0 -gui tray=setpass" might be something for them that they are accustomed to in a Desktop environment (it prompts for an initial password, etc.) This is a basic "Share My Desktop" usage mode. As of Nov/2008 in x11vnc 0.9.6 there is a desktop menu item (x11vnc.desktop) that runs this command: ``` x11vnc -gui tray=setpass -rfbport PROMPT -logfile %HOME/.x11vnc.log.%VNCDISPLAY ``` which also prompts for which VNC port to use and a couple other parameters. ### Q-10: How can I get x11vnc to listen on a different port besides the default VNC port (5900)? Use something like, e.g., "x11vnc -rfbport 5901" to force it to use port 5901 (this is VNC display :1.) If something else is using that port x11vnc will exit immediately. If you do not supply the -rfbport option, it will autoprobe starting at 5900 and work its way up to 5999 looking for a free port to listen on. In that case, watch for the PORT=59xx line to see which port it found, then subtract 5900 from it for the VNC display number to enter into the VNC Viewer(s). The "-N" option will try to match the VNC display number to the X display (e.g. X11 DISPLAY of :5 (port 6005) will have VNC display :5 (port 5905).) Also see the "-autoport n" option to indicated at which value the auto probing should start at. ### Q-11: My Firewall/Router doesn't allow VNC Viewers to connect to x11vnc. See the Firewalls/Routers discussion. ### Q-12: Is it possible for a VNC Viewer and a VNC Server to connect to each other even though both are behind Firewalls that block all incoming connections? This is very difficult or impossible to do unless a third machine, reachable by both, is used as a relay. So we assume a third machine is somehow being used as a relay. (Update: It may be possible to do "NAT-2-NAT" without a relay machine by using a UDP tunnel such as http://samy.pl/pwnat/. All that is required is that both NAT firewalls allow in UDP packets from an IP address to which a UDP packet has recently been sent to. If you try it out let us know how it went.) In the following discussion, we will suppose port 5950 is being used on the relay machine as the VNC port for the rendezvous. A way to rendezvous is to have the VNC Server start a reverse connection to the relay machine: x11vnc -connect third-machine.net:5950 ... and the VNC viewer forward connects as usual: vncviewer third-machine.net:50 Or maybe two ports would be involved, e.g. the viewer goes to display :51 (5951.) It depends on the relay software being used. What software to run on third-machine? A TCP relay of some sort could be used... Try a google search on "tcp relay" or "ip relay". However, note that this isn't a simple redirection because it hooks up two incoming connections. You can look at our UltraVNC repeater implementation ultravnc_repeater.pl for ideas and possibly to customize. Also, if you are not the admin of third-machine you'd have to convince the owner to allow you to install this software (and he would likely need to open his server's firewall to allow the port through.) It is recommended that SSL is used for encryption (e.g. "-ssl SAVE") when going over the internet. We have a prototype for performing a rendezvous via a Web Server acting as the relay machine. Download the vncxfer CGI script and see the instructions at the top. Once that CGI script is set up on the website, both users go to, say, http://somesite.com/vncxfer (or maybe a "/cgi-bin" directory or ".cgi" suffix must be used.) Previously, both have agreed on the same session name (say by phone or email) , e.g. "5cows", and put that into the entry form on the vncxfer starting page (hopefully separated by a few seconds, so the relay helper can fully start up at the first request.) The page returned tells them the hostname and port number and possible command to use for forward (VNC Viewer) and reverse (VNC Server, i.e. x11vnc) connections as described above. Also since Oct/2007, x11vnc can connect directly (no web browser), like this: ``` x11vnc ... -connect localhost:0 -proxy 'http://somesite.com/vncxfer?session=5cows&' ``` Unfortunately the prototype requires that the Web server's firewall allow in the port (e.g. 5950) used for the rendezvous. Most web servers are not configured to do this, so you would need to ask the admin to do this for you. Nearly all free webspace sites, e.g. www.zendurl.com, will not allow your CGI script to be an open relay like this. (If you find one that does allow this, let me know!) Maybe someday a clever trick will be thought up to relax the listening port requirement (e.g. use HTTP/CGI itself for the transfer... it is difficult to emulate a full-duplex TCP connection with them.) See also the Firewalls/Routers discussion and Reverse Connection Proxy discussion. SSH method: If both users (i.e. one on Viewer-side and the other on x11vnc server side) have SSH access to a common machine on the internet (or otherwise mutually reachable), then SSH plumbing can be used to solve this problem. The users create SSH tunnels going through the SSH login machine. Instead of assuming port 5900 is free on the SSH machine, we will assume both users agreed to use 5933. This will illustrate how to use a different port for the redir. It could be any port, what matters is that both parties refer to the same one. Set up the Tunnel from the VNC Server side: ``` ssh -t -R 5933:localhost:5900 user@third-machine.net ``` Set up the Tunnel from the VNC Viewer side: ``` ssh -t -L 5900:localhost:5933 user@third-machine.net ``` Run Server on the VNC Server side: ``` x11vnc -rfbport 5900 -localhost ... ``` Run Viewer on the VNC Viewer side: ``` vncviewer -encodings "copyrect tight zrle hextile" localhost:0 ``` (we assume the old-style -encodings option needs to be used. See here for details.) If the SSH machine has been configured (see sshd_config(5)) with the option GatewayPorts=yes, then the tunnel set up by the VNC Server will be reachable directly by the VNC viewer (as long as the SSH machine's firewall does not block the port, 5933 in this example.) So in that case the Viewer side does not need to run any ssh command, but rather only runs: vncviewer third-machine.net:33 In this case we recommend SSL be used for encryption. The creation of both tunnels can be automated. As of Oct/2007 the -ssh x11vnc option is available and so only this command needs to be run on the VNC Server side: x11vnc -ssh user@third-machine.net:33 ... (the SSH passphrase may need to be supplied.) To automate on the VNC Viewer side, the user can use the Enhanced TightVNC Viewer (SSVNC) by: * Clicking on 'Use SSH' * Entering user@third-machine.net:33 into 'VNC Host:Display' entry box * Clicking on 'Connect' As above, if the SSH GatewayPorts=yes setting is configured the Viewer side doesn't need to create a SSH tunnel. In SSVNC the Viewer user could instead select 'Use SSL' and then, e.g., on the Server side supply "-ssl SAVE" to x11vnc. Then end-to-end SSL encryption would be used (in addition to the SSH encryption on the Server-side leg.) ### Q-13: Can I make x11vnc more quiet and also go into the background after starting up? Use the -q and -bg options, respectively. (also: -quiet is an alias for -q) Note that under -bg the stderr messages will be lost unless you use the "-o logfile" option. ### Q-14: Sometimes when a VNC viewer dies abruptly, x11vnc also dies with the error message like: "Broken pipe". I'm using the -forever mode and I want x11vnc to keep running. As of Jan/2004 the SIGPIPE signal is ignored. So if a viewer client terminates abruptly, libvncserver will notice on the next I/O operation and will close the connection and continue on. Up until of Apr/2004 the above fix only works for BSD signal systems (Linux, FreeBSD, ...) For SYSV systems there is a workaround in place since about Jun/2004. ### Q-15: The Windows TightVNC 1.3.9 Viewer cannot connect to x11vnc. This appears to be fixed in x11vnc version 0.9 and later. If you need to use an earlier version of x11vnc, try using the "-rfbversion 3.7" option. In general sometimes one can get a misbehaving viewer to work by supplying rfb versions 3.7 or 3.3. ### Q-16: KDE's krdc VNC viewer cannot connect to x11vnc. This has been fixed in x11vnc version 0.8.4. More info here, here, and here. ### Q-17: When I start x11vnc on an Alpha Tru64 workstation the X server crashes! This is a bug in the X server obviously; an X client should never be able to crash it. The problem seems to be with the RECORD X extension and so a workaround is to use the "-noxrecord" x11vnc command line option. ### Q-18: When running x11vnc on an IBM AIX workstation after a few minutes the VNC connection freezes. One user reports when running x11vnc on AIX 5.3 in his CDE session after a few minutes or seconds x11vnc will "freeze" (no more updates being sent, etc.) The freezing appeared to be worse for versions later than 0.9.2. The problem seems to be with the RECORD X extension on AIX and so a workaround is to use the "-noxrecord" x11vnc command line option. The user found no freezes occurred when using that option. ### Q-19: Are there any build-time customizations possible, e.g. change defaults, create a smaller binary, etc? There are some options. They are enabled by adding something like -Dxxxx=1 to the CPPFLAGS environment variable before running configure (see the build notes for general background.) ``` /* * Mar/2006 * Build-time customization via CPPFLAGS. * * Summary of options to include in CPPFLAGS for custom builds: * * -DVNCSHARED to have the vnc display shared by default. * -DFOREVER to have -forever on by default. * -DNOREPEAT=0 to have -repeat on by default. * -DADDKEYSYMS=0 to have -noadd_keysyms the default. * * -DREMOTE_DEFAULT=0 to disable remote-control on by default (-yesremote.) * -DREMOTE_CONTROL=0 to disable remote-control mechanism completely. * -DEXTERNAL_COMMANDS=0 to disable the running of all external commands. * -DFILEXFER=0 disable filexfer. * * -DHARDWIRE_PASSWD=... hardwired passwords, quoting necessary. * -DHARDWIRE_VIEWPASSWD=... * -DNOPW=1 make -nopw the default (skip warning) * -DUSEPW=1 make -usepw the default * -DPASSWD_REQUIRED=1 exit unless a password is supplied. * -DPASSWD_UNLESS_NOPW=1 exit unless a password is supplied and no -nopw. * * -DWIREFRAME=0 to have -nowireframe as the default. * -DWIREFRAME_COPYRECT=0 to have -nowirecopyrect as the default. * -DWIREFRAME_PARMS=... set default -wirecopyrect parameters. * -DSCROLL_COPYRECT=0 to have -noscrollcopyrect as the default. * -DSCROLL_COPYRECT_PARMS=... set default -scrollcopyrect parameters. * -DSCALING_COPYRECT=0 * -DXDAMAGE=0 to have -noxdamage as the default. * -DSKIPDUPS=0 to have -noskip_dups as the default or vice versa. * * -DPOINTER_MODE_DEFAULT={0,1,2,3,4} set default -pointer_mode. * -DBOLDLY_CLOSE_DISPLAY=0 to not close X DISPLAY under -rawfb. * -DSMALL_FOOTPRINT=1 for smaller binary size (no help, no gui, etc) * use 2 or 3 for even smaller footprint. * -DNOGUI do not include the gui tkx11vnc. * -DPOLL_8TO24_DELAY=N * -DDEBUG_XEVENTS=1 enable printout for X events. * * Set these in CPPFLAGS before running configure. E.g.: * * % env CPPFLAGS="-DFOREVER -DREMOTE_CONTROL=0" ./configure * % make */ ``` If other things (e.g. "-I ...") are needed in CPPFLAGS add them as well. On some systems is seems you need to set LC_ALL=C for configure to work properly... Be careful the following two variables: HARDWIRE_PASSWD and HARDWIRE_VIEWPASSWD. If set (remember to include the double quotes around the string), they will be used as default values for the -passwd and -viewpasswd options. Of course the strings will exist unobscured in the x11vnc binary: it better not be readable by unintendeds. Perhaps this is of use in remote access for an embedded application, etc... Let us know if more build-time customizations would be useful. ## Win2VNC Related ### Q-20: I have two separate machine displays in front of me, one Windows the other X11: can I use x11vnc in combination with Win2VNC in dual-screen mode to pass the keystrokes and mouse motions to the X11 display? Yes, for best response start up x11vnc with the "-nofb" option (disables framebuffer polling, and does other optimizations) on the secondary display (X11) machine. Then start up Win2VNC on the primary display (Windows) referring it to the secondary display. This will also work X11 to X11 using x2vnc, however you would probably just want to avoid VNC and use x2x for that. For reference, here are some links to Win2VNC-like programs for multiple monitor setups: * Original Win2VNC * Enhanced Win2VNC (broken?) and sourceforge link * x2vnc * x2x * zvnc (MorphOS) All of them will work with x11vnc (except x2x where it is not needed.) ### Q-21: I am running Win2VNC on my Windows machine and "x11vnc -nofb" on Unix to pass keyboard and mouse to the Unix monitor. Whenever I start Win2VNC it quickly disconnects and x11vnc says: rfbProcessClientNormalMessage: read: Connection reset by peer Is the default visual of the X display you run x11vnc on low color (e.g. 8 bit per pixel PseudoColor)? (you can run xdpyinfo to check, look in the "screen" section.) There seems to be a bug in Win2VNC in that it cannot deal correctly with colormaps (PseudoColor is the most common example of a visual with a colormap.) If so, there are a couple options. 1) Can you set the default visual on your display to be depth 24 TrueColor? Sun machines often have 8+24 overlay/multi-depth visuals, and you can make the default visual depth 24 TrueColor (see fbconfig(1) and Xsun(1).) 2) As of Feb/2004 x11vnc has the -visual option to allow you to force the framebuffer visual to whatever you want (this usually messes up the colors unless you are very clever.) In this case, the option provides a convenient workaround for the Win2VNC bug: ``` x11vnc -nofb -visual TrueColor -display :0 ... ``` So the visual will be set to 8bpp TrueColor and Win2VNC can handle this. Since Win2VNC does not use the framebuffer data there should be no problems in doing this. ### Q-22: Can I run "x11vnc -nofb" on a Mac OS X machine to redirect mouse and keyboard input to it from Windows and X11 machines via Win2VNC and x2vnc, respectively? Yes, as of Nov/2006 you can. There may be a trick or two you'll need to do to get the Clipboard exchange between the machines to work. ## Color Issues ### Q-23: The X display I run x11vnc on is only 8 bits per pixel (bpp) PseudoColor (i.e. only 256 distinct colors.) The x11vnc colors may start out OK, but after a while they are incorrect in certain windows. Use the -flashcmap option to have x11vnc watch for changes in the colormap, and propagate those changes back to connected clients. This can be slow (since the whole screen must be updated over the network whenever the colormap changes.) This flashing colormap behavior often happens if an application installs its own private colormap when the mouse is in its window. "netscape -install" is a well-known historical example of this. Consider reconfiguring the system to 16 bpp or depth 24 TrueColor if at all possible. Also note the option -8to24 (Jan/2006) can often remove the need for flashing the colormap. Everything is dynamically transformed to depth 24 at 32 bpp using the colormaps. There may be painting errors however (see the following FAQ for tips on reducing and correcting them.) In some rare cases (SCO unixware) the -notruecolor option has corrected colors on 8bpp displays. The red, green, and blue masks were non-zero in 8bpp PseudoColor on an obscure setup, and this option corrected the problems. ### Q-24: Color problems: Why are the colors for some windows incorrect in x11vnc? BTW, my X display has nice overlay/multi-depth visuals of different color depths: e.g. there are both depth 8 and 24 visuals available at the same time. You may want to review the previous question regarding 8 bpp PseudoColor. On some hardware (Sun/SPARC and SGI), the -overlay option discussed a couple paragraphs down may solve this for you (you may want to skip to it directly.) On other hardware the less robust -8to24 option may help (also discussed below.) Run xdpyinfo(1) to see what the default visual is and what the depths of the other visuals are. Does the default visual have a depth of 8 but there are other visuals of depth 24? If it does, can you possibly re-configure your X server to make a depth 24 visual the default? If you can do it, this will save you a lot of grief WRT colors and x11vnc (and for general usage too!) Here is how I do this on an old Sparcstation 20 running Solaris 9 with SX graphics ``` xinit -- -dev /dev/fb defclass TrueColor defdepth 24 ``` and it works nicely (note: to log into console from the dtlogin window, select "Options -> Command Line Login", then login and enter the above command.) See the -dev section of the Xsun(1) manpage for a description of the above arguments. If you have root permission, a more permanent and convenient thing to do is to record the arguments in a line like: ``` :0 Local local_uid@console root /usr/openwin/bin/Xsun -dev /dev/fb defclass TrueColor defdepth 24 ``` in /etc/dt/config/Xservers (copy /usr/dt/config/Xservers.) Also look at the fbconfig(1) and related manpages (e.g. ffbconfig, m64config, pgxconfig, SUNWjfb_config, etc ...) for hardware framebuffer settings that may achieve the same effect. In general for non-Sun machines, look at the "-cc class" and related options in your X server manpage (perhaps Xserver(1)), it may allow modifying the default visual (e.g. "-cc 4", see for the visual class numbers.) On XFree86 some video card drivers (e.g. Matrox mga) have settings like Option "Overlay" "24,8" to support multi-depth overlays. For these, use the "-cc 4" X server command line option to get a depth 24 default visual. The -overlay mode: Another option is if the system with overlay visuals is a Sun system running Solaris or SGI running IRIX you can use the -overlay x11vnc option (Aug/2004) to have x11vnc use the Solaris XReadScreen(3X11) function to poll the "true view" of the whole screen at depth 24 TrueColor. XReadDisplay(3X11) is used on IRIX. This is useful for Legacy applications (older versions of Cadence CAD apps are mentioned by x11vnc users) that require the default depth be 8bpp, or the app will use a 8bpp visual even if depth 24 visuals are available, and so the default depth workaround described in the previous paragraph is not sufficient for these apps. It seems that Xorg is working toward supporting XReadDisplay(3X11) as part of the RENDER extension work. When it does support it and provides a library API x11vnc will be modified to take advantage of the feature to support -overlay on Linux, *BSD, etc. Until then see the -8to24 mode below. Misc. notes on -overlay mode: An amusing by-product of -overlay mode is that the mouse cursor shape is correct! (i.e. XFIXES is not needed.) The -overlay mode may be somewhat slower than normal mode due to the extra framebuffer manipulations that must be performed. Also, on Solaris there is a bug in that for some popup menus, the windows they overlap will have painting errors (flashing colors) while the popup is up (a workaround is to disable SaveUnders by passing -su to Xsun, e.g. in your /etc/dt/config/Xservers file.) The -8to24 mode: The -8to24 x11vnc option (Jan/2006) is a kludge to try to dynamically rewrite the pixel values so that the 8bpp part of the screen is mapped onto depth 24 TrueColor. This is less robust than the -overlay mode because it is done by x11vnc outside of the X server. So only use it on OS's that do not support -overlay. The -8to24 mode will work if the default visual is depth 24 or depth 8. It scans for any windows within 3 levels of the root window that are 8bpp (i.e. legacy application), or in general ones that are not using the default visual. For the windows it finds it uses XGetSubImage() to retrieve the pixels values and uses the correct indexed colormap to create a depth 24 TrueColor view of the whole screen. This depth 24, 32bpp view is exported via VNC. Even on pure 8bpp displays it can be used as an alternative to -flashcmap to avoid color flashing completely. This scheme is approximate and can often lead to painting errors. You can manually correct most painting errors by pressing 3 Alt_L's in a row, or by using something like: -fixscreen V=3.0 to automatically refresh the screen every 3 seconds. Also -fixscreen 8=3.0 has been added to just refresh the non-default visual parts of the screen. In general the scheme uses many resources and may give rise to sluggish behavior. If multiple windows are using different 8bpp indexed colormaps all but one window may need to be iconified for the colors to be correct. There are a number of tunable parameters to try to adjust performance and painting accuracy. The option -8to24 nogetimage can give a nice speedup if the default depth 24 X server supports hiding the 8bpp bits in bits 25-32 of the framebuffer data. On very slow machines -8to24 poll=0.2,cachewin=5.0 gives an useful speedup. See the -8to24 help description for information on tunable parameters, etc. Colors still not working correctly? Run xwininfo on the application with the incorrect colors to verify that the depth of its visual is different from the default visual depth (gotten from xdpyinfo.) One possible workaround in this case is to use the -id option to point x11vnc at the application window itself. If the application is complicated (lots of toplevel windows and popup menus) this may not be acceptable, and may even crash x11vnc (but not the application.) See also -appshare. It is theoretically possible to solve this problem in general (see xwd(1) for example), but it does not seem trivial or sufficiently fast for x11vnc to be able to do so in real time. The -8to24 method does this approximately and is somewhat usable. Fortunately the -overlay option works for Solaris machines with overlay visuals where most of this problem occurs. ### Q-25: I am on a high color system (depth >= 24) but I seem to have colormap problems. They either flash or everything is very dark. This can happen if the default Visual (use xdpyinfo to list them) is DirectColor instead of TrueColor. These are both usually used in high color modes, but whereas TrueColor uses static ramps for the Red, Green, and Blue components, DirectColor has arbitrary colormaps for the Red, Green, and Blue Components. Currently x11vnc cannot decode these colormaps and treats them just like TrueColor. The only workaround so far is to restart the X server with the "-cc 4" option to force TrueColor as the default visual (DirectColor is "-cc 5"; see /usr/include/X11/X.h.) The only place we have seen this is with the virtual framebuffer server Xvfb on Xorg 7.2. So in that case you probably should restart it with something like this: "Xvfb :1 -cc 4 -screen 0 1280x1024x24". It should be possible for x11vnc to handle DirectColor, but this hasn't been implemented due to its rare usage. You may also see this problem on an X display with a TrueColor default visual where an application chooses a DirectColor visual for its window(s). It seems the application also needs to install its own colormap for the visual for the colors to be messed up in x11vnc. One can make xwud do this for example. ### Q-26: How do I figure out the window id to supply to the -id windowid option? Run the xwininfo program in a terminal. It will ask you to click on the desired application window. After clicking, it will print out much information, including the window id (e.g. 0x6000010.) Also, the visual and depth of the window printed out is often useful in debugging x11vnc color problems. Also, as of Dec/2004 you can use "-id pick" to have x11vnc run xwininfo(1) for you and after you click the window it extracts the windowid. Besides "pick" there is also "id:root" to allow you to go back to root window when doing remote-control. ### Q-27: Why don't menus or other transient windows come up when I am using the -id windowid option to view a single application window? This is related to the behavior of the XGetImage(3X11) and XShmGetImage() interfaces regarding backingstore, saveunders, etc. The way the image is retrieved depends on some aspects of how the X server maintains the display image data and whether other windows are clipping or obscuring it. See the XGetImage(3X11) man page for more details. If you disable BackingStore and SaveUnders in the X server you should be able to see these transient windows. If things are not working and you still want to do the single window polling, try the -sid windowid option ("shifted" windowid.) Update: as of Nov/2009 in the 0.9.9 x11vnc development tarball, there is an experimental Application Sharing mode that improves upon the -id/-sid single window sharing: -appshare (run "x11vnc -appshare -help" for more info.) It is still very primitive and approximate, but at least it displays multiple top-level windows. ### Q-28: My X display is depth 24 at 24bpp (instead of the normal depth 24 at 32bpp.) I'm having lots of color and visual problems with x11vnc and/or vncviewer. What's up? First off, depth 24 at 24bpp (bpp=bits-per-pixel) is fairly uncommon and can cause problems in general. It also can be slower than depth 24 at 32bpp. You might want to switch to 32bpp (for XFree86 see the "-fbbpp 32", DefaultFbBpp, FbBpp and related options.) Perhaps you have 24bpp because the video memory of the machine is low and the screen wouldn't fit in video RAM at 32bpp. For this case depth 16 at 16bpp might be an acceptable option. In any event x11vnc should handle depth 24 at 24bpp (although performance may be slower, and you may need to use the ZRLE encoding instead of Tight.) There are some caveats involving the viewer however: The RealVNC Unix viewer cannot handle 24bpp from the server, it will say: "main: setPF: not 8, 16 or 32 bpp?" and exit. I have not checked the RealVNC Windows viewer. So you need to use the TightVNC Unix viewer. However there are some problems with that too. It seems libvncserver does not do 24bpp correctly with the Tight encoding. The colors and screen ultimately get messed up. So you have to use a different encoding with the TightVNC vncviewer, try "zlib", "hextile", or one of the other encodings (e.g. vncviewer -encodings "zlib hextile" ....) I have not checked the TightVNC or UltraVNC Windows viewers. It appears the older RealVNC Unix viewers (e.g. 3.3.3 and 3.3.7) can handle 24bpp from the server, so you may want to use those. They evidently request 32 bpp and libvncserver obliges. Update: as of Apr/2006 you can use the -24to32 option to have x11vnc dynamically transform the 24bpp pixel data to 32bpp. This extra transformation could slow things down further however. Now coming the opposite direction if you are running the vncviewer on the 24bpp display, TightVNC will fail with "Can't cope with 24 bits-per-pixel. Sorry." and RealVNC will fail with "main: Error: couldn't find suitable pixmap format" so evidently you cannot use 24bpp for the vncviewers to work on that X display. Note, however, that the Unix viewer in the Enhanced TightVNC Viewer (SSVNC) project can handle 24bpp X displays. It does this by requesting a 16bpp pixel format (or 8bpp if the -bgr233 option has been supplied) from the VNC server, and translates that to 24bpp locally. ## Xterminals ### Q-29: Can I use x11vnc to view and interact with an Xterminal (e.g. NCD) that is not running UNIX and so x11vnc cannot be run on it directly? You can, but it will likely be very wasteful of network bandwidth since you will be polling the X display over the network as opposed to over the local hardware. To do this, run x11vnc on a UNIX machine as close as possible network-wise (e.g. same switch) to the Xterminal machine. Use the -display option to point the display to that of the Xterminal (you'll of course need basic X11 permission to do that) and finally supply the -noshm option (this enables the polling over the network.) If the Xterminal's X display is open to the network for connections, you might use something like "-display xterm123:0". If you are trying to do this via an SSH tunnel (assuming you can actually ssh into the Xterminal) it will be a little tricky (either use the ssh "-R" option or consider ssh-ing in the other direction.) In all cases the X11 permissions need to allow the connection. The response will likely be sluggish (maybe only one "frame" per second.) This mode is not recommended except for "quick checks" of hard to get to X servers. Use something like "-wait 150" to cut down on the polling rate. You may also need -flipbyteorder if the colors get messed up due to endian byte order differences. ### Q-30: How do I get my X permissions (MIT-MAGIC-COOKIE file) correct for a Unix/Linux machine acting as an Xterminal? If the X display machine is a traditional Xterminal (where the X server process runs on the Xterminal box, but all of the X client applications (firefox, etc) run on a central server (aka "terminal server")), you will need to log into the Xterminal machine (i.e. get a shell running there) and then start the x11vnc program. If the Xterminal Linux/Unix machine is stripped down (e.g. no users besides root) that may be difficult. The next problem is the login Display Manager (e.g. gdm, kdm), and hence the MIT-MAGIC-COOKIE auth files, are on the central server and not on the Xterminal box where the X server and x11vnc processes are. So unless X permissions are completely turned off (e.g. "xhost +"), to run the x11vnc process on the Xterminal box the MIT-MAGIC-COOKIE auth file data (XAUTHORITY or $HOME/.Xauthority) must be accessible by or copied to the Xterminal. If $HOME/.Xauthority is exported via NFS (this is insecure of course, but has been going on for decades), then x11vnc can simply pick it up via NFS (you may need to use the -auth option to point to the correct file.) Other options include copying the auth file using scp, or something like: ``` central-server> xauth nextract - xterm123:0 | ssh xterm123 xauth nmerge - ``` and then, say, ssh from central-server to xterm123 to start x11vnc. Here "xterm123" refers to the computer acting as the Xterminal and "central-server" is the terminal server. You can use "xauth -f /path/to/cookie-file list" to examine the contents of the cookie(s) in a file "/path/to/cookie-file". See the xauth(1) manpage for more details. If the display name in the cookie file needs to be changed between the two hosts, see this note on the "xauth add ..." command. A less secure option is to run something like "xhost +127.0.0.1" while sitting at the Xterminal box to allow cookie-free local access for x11vnc. You can run "xhost -127.0.0.1" after x11vnc connects if you want to go back to the original permissions. If the Xterminal is really stripped down and doesn't have any user accounts, NFS, etc. you'll need to contact your system administrator to set something up. It can be done!!! Some Xterminal projects have actually enabled "run locally" facilities for the running of an occasional app more efficiently locally on the Xterminal box (e.g. realplayer.) Not recommended, but as a last resort, you could have x11vnc poll the Xterminal Display over the network. For this you would run a "x11vnc -noshm ..." process on the central-server (and hope the network admin doesn't get angry...) Note: use of Display Manager (gdm, kdm, ...) auth cookie files (i.e. from /var/..., /tmp/..., or elsewhere) may require modification via xauth(1) to correctly include the display x11vnc refers to (e.g. "xauth -f cookie-file add :0 . 45be51ae2ce9dfbacd882ab3ef8e96b1", where the "45be51..." cookie value was found from an "xauth -f /path/to/original/cookie-file list") or other reasons. See xauth(1) manpage for full details on how to transfer an MIT-MAGIC-COOKIE between machines and displays. VNCviewer performance on Xterminals: This isn't related to x11vnc on Xterminals, but we mention it here anyway because of the similar issues. If you are on an Xterminal and want to use vncviewer to connect to a VNC server somewhere, then performance would be best if you ran the viewer on the Xterminal box. Otherwise, (i.e. running the viewer process on the central-server) all of the vncviewer screen drawing is done more inefficiently over the network. Something to consider, especially on a busy network. (BTW, this has all of the above permission, etc, problems: both vncviewer and x11vnc are X client apps desired to be run on the Xterminal box.) ## Sun Rays ### Q-31: I'm having trouble using x11vnc with my Sun Ray session. The Sun Ray technology is a bit like "VNC done in hardware" (the Sun Ray terminal device, DTU, playing the role of the vncviewer.) Completely independent of that, the SunRay user's session is still an X server that speaks the X11 protocol and so x11vnc simply talks to the X server part to export the SunRay desktop to any place in the world (i.e. not only to a Sun Ray terminal device), creating a sort of "Soft Ray". Please see this discussion of Sun Ray issues for solutions to problems. Also see the Sun Ray Remote Control Toolkit that uses x11vnc. ## Remote Control ### Q-32: How do I stop x11vnc once it is running in the background? As of Dec/2004 there is a remote control feature. It can change a huge number of parameters on the fly: see the -remote and -query options. To shut down the running x11vnc server just type "x11vnc -R stop". To disconnect all clients do "x11vnc -R disconnect:all", etc. If the -forever option has not been supplied, x11vnc will automatically exit after the first client disconnects. In general if you cannot use the remote control, then you will have to kill the x11vnc process This can be done via: "kill NNNNN" (where NNNNN is the x11vnc process id number found from ps(1)), or "pkill x11vnc", or "killall x11vnc" (Linux only.) If you have not put x11vnc in the background via the -bg option or shell & operator, then simply press Ctrl-C in the shell where x11vnc is running to stop it. Potential Gotcha: If somehow your Keypress of Ctrl-C went through x11vnc to the Xserver that then delivered it to x11vnc it is possible one or both of the Ctrl or C keys will be left stuck in the pressed down state in the Xserver. Tapping the stuck key (either via a new x11vnc or at the physical console) will release it from the stuck state. If the keyboard seems to be acting strangely it is often fixed by tapping Ctrl, Shift, and Alt. Alternatively, the -clear_mods option and -clear_keys option can be used to release pressed keys at startup and exit. The option -clear_all will also try to unset Caps_Lock, Num_Lock, etc. ### Q-33: Can I change settings in x11vnc without having to restart it? Can I remote control it? Look at the -remote (an alias is -R) and -query (an alias is -Q) options added in Dec/2004. They allow nearly everything to be changed dynamically and settings to be queried. Examples: "x11vnc -R shared", "x11vnc -R forever", "x11vnc -R scale:3/4", "x11vnc -Q modtweak", "x11vnc -R stop", "x11vnc -R disconnect:all", etc.. These commands do not start a x11vnc server, but rather communicate with one that is already running. The X display (X11VNC_REMOTE property) is used as the communication channel, so the X permissions and DISPLAY must be set up correctly for communication to be possible. There is also a simple Tcl/Tk gui based on this remote control mechanism. See the -gui option for more info. You will need to have Tcl/Tk (i.e. /usr/bin/wish) installed for it to work. It can also run in the system tray: "-gui tray" or as a standalone small icon window: "-gui icon". Use "-gui tray=setpass" for a naive user "Share My Desktop" mode. ## Security and Permissions ### Q-34: How do I create a VNC password for use with x11vnc? You may already have one in $HOME/.vnc/passwd if you have used, say, the vncserver program from the regular RealVNC or TightVNC packages (i.e. launching the Xvnc server.) Otherwise, you could use the vncpasswd(1) program from those packages. As of Jun/2004 x11vnc supports the -storepasswd "pass" "file" option, which is the same functionality of storepasswd. Be sure to quote the "pass" if it contains shell meta characters, spaces, etc. Example: ``` x11vnc -storepasswd 'sword*fish' $HOME/myvncpasswd ``` You then use the password via the x11vnc option: "-rfbauth $HOME/myvncpasswd" As of Jan/2006 if you do not supply any arguments: ``` x11vnc -storepasswd ``` you will be prompted for a password to save to ~/.vnc/passwd (your keystrokes when entering the password will not be echoed to the screen.) If you supply one argument, e.g. "x11vnc -storepasswd ~/.mypass", the password you are prompted for will be stored in that file. x11vnc also has the -passwdfile and -passwd/-viewpasswd plain text (i.e. not obscured like the -rfbauth VNC passwords) password options. You can use the -usepw option to automatically use any password file you have in ~/.vnc/passwd or ~/.vnc/passwdfile (the latter is used with the -passwdfile option.) ``` x11vnc -usepw -display :0 ... ``` If neither file exists you are prompted to store a password in ~/.vnc/passwd. If a password file cannot be found or created x11vnc exits immediately. An admin may want to set it up this way for users who do not know better. ### Q-35: Can I make it so -storepasswd doesn't show my password on the screen? You can use the vncpasswd program from RealVNC or TightVNC mentioned above. As of Jan/2006 the -storepasswd option without any arguments will not echo your password as you type it and save the file to ~/.vnc/passwd: ``` # x11vnc -storepasswd Enter VNC password: Verify password: Write password to /home/myname/.vnc/passwd? [y]/n Password written to: /home/myname/.vnc/passwd ``` You can also give it an alternate filename, e.g. "x11vnc -storepasswd ~/.mypass" ### Q-36: Can I have two passwords for VNC viewers, one for full access and the other for view-only access to the display? Yes, as of May/2004 there is the -viewpasswd option to supply the view-only password. Note the full-access password option -passwd must be supplied at the same time. E.g.: -passwd sword -viewpasswd fish. To avoid specifying the passwords on the command line (where they could be observed via the ps(1) command by any user) you can use the -passwdfile option to specify a file containing plain text passwords. Presumably this file is readable only by you, and ideally it is located on the machine x11vnc is run on (to avoid being snooped on over the network.) The first line of this file is the full-access password. If there is a second line in the file and it is non-blank, it is taken as the view-only password. (use "__EMPTY__" to supply an empty one.) View-only passwords currently do not work for the -rfbauth password option (standard VNC password storing mechanism.) FWIW, note that although the output (usually placed in $HOME/.vnc/passwd) by the vncpasswd or storepasswd programs (or from x11vnc -storepasswd) looks encrypted they are really just obscured to avoid "casual" password stealing. It takes almost no skill to figure out how to extract the plain text passwords from $HOME/.vnc/passwd since it is very straight-forward to work out what to do from the VNC source code. ### Q-37: Can I have as many full-access and view-only passwords as I like? Yes, as of Jan/2006 in the libvncserver CVS the -passwdfile option has been extended to handle as many passwords as you like. You put the view-only passwords after a line __BEGIN_VIEWONLY__. You can also easily annotate and comment out passwords in the file. You can have x11vnc re-read the file dynamically when it is modified. ### Q-38: Does x11vnc support Unix usernames and passwords? Can I further limit the set of Unix usernames who can connect to the VNC desktop? Update: as of Feb/2006 x11vnc has the -unixpw option that does this outside of the VNC protocol and libvncserver. The standard su(1) program is used to validate the user's password. A familiar "login:" and "Password:" dialog is presented to the user on a black screen inside the vncviewer. The connection is dropped if the user fails to supply the correct password in 3 tries or does not send one before a 25 second timeout. Existing clients are view-only during this period. A list of allowed Unix usernames may also be supplied along with per-user settings. There is also the -unixpw_nis option for non-shadow-password (typically NIS environments, hence the name) systems where the traditional getpwnam() and crypt() functions are used instead of su(1). The encrypted user passwords must be accessible to the user running x11vnc in -unixpw_nis mode, otherwise the logins will always fail even when the correct password is supplied. See ypcat(1) and shadow(5). Two settings are enforced in the -unixpw and -unixpw_nis modes to provide extra security: the 1) -localhost and 2) -stunnel or -ssl options. Without these one might send the Unix username and password data in clear text over the network which is a very bad idea. They can be relaxed if you want to provide encryption other than stunnel or -ssl (the constraint is automatically relaxed if SSH_CONNECTION is set and indicates you have ssh-ed in, however the -localhost requirement is still enforced.) The two -unixpw modes have been tested on Linux, Solaris, Mac OS X, HP-UX, AIX, Tru64, FreeBSD, OpenBSD, and NetBSD. Additional testing is appreciated. For the last 4 it appears that su(1) will not prompt for a password if su-ing to oneself. Since x11vnc requires a password prompt from su, x11vnc forces those logins to fail even when the correct password is supplied. On *BSD it appears this can be corrected by removing the pam_self.so entry in /etc/pam.d/su. Previous older discussion (prior to the -unixpw option): Until the VNC protocol and libvncserver support this things will be approximate at best. One approximate method involves starting x11vnc with the -localhost option. This basically requires the viewer user to log into the workstation where x11vnc is running via their Unix username and password, and then somehow set up a port redirection of his vncviewer connection to make it appear to emanate from the local machine. As discussed above, ssh is useful for this: "ssh -L 5900:localhost:5900 user@hostname ..." See the ssh wrapper scripts mentioned elsewhere on this page. stunnel does this as well. Of course a malicious user could allow other users to get in through his channel, but that is a problem with every method. Another thing to watch out for is a malicious user on the viewer side (where ssh is running) trying to sneak in through the ssh port redirection there. Regarding limiting the set of Unix usernames who can connect, the traditional way would be to further require a VNC password to supplied (-rfbauth, -passwd, etc) and only tell the people allowed in what the VNC password is. A scheme that avoids a second password involves using the -accept option that runs a program to examine the connection information to determine which user is connecting from the local machine. That may be difficult to do, but, for example, the program could use the ident service on the local machine (normally ident should not be trusted over the network, but on the local machine it should be accurate: otherwise root has been compromised and so there are more serious problems! Unfortunately recent Linux distros seem to provide a random string (MD5 hash?) instead of the username.) An example script passed in via -accept scriptname that deduces the Unix username and limits who can be accepted might look something like this: ``` #!/bin/sh if [ "$RFB_CLIENT_IP" != "127.0.0.1" -o "$RFB_SERVER_IP" != "127.0.0.1" ]; then exit 1 # something fishy... reject it. fi user=`echo "$RFB_CLIENT_PORT, $RFB_SERVER_PORT" | nc -w 1 $RFB_CLIENT_IP 113 \ | grep 'USERID.*UNIX' | head -n 1 | sed -e 's/[\r ]//g' | awk -F: '{pri nt $4}'` for okuser in fred barney wilma betty do if [ "X$user" = "X$okuser" ]; then exit 0 # accept it fi done exit 1 # reject it For this to work with ssh port redirection, the ssh option UsePrivilegeSeparation must be enabled otherwise the userid will always be "root". Here is a similar example based on Linux netstat(1) output: #!/bin/sh # # accept_local_netstat: x11vnc -accept command to accept a local # vncviewer connection from acceptable users. Linux netstat -nte is used. PATH=/bin:/usr/bin:$PATH; export PATH; # set to get system utils allowed="`id -u fred`"; # add more user numbers if desired. # check required settings ok=1 if [ "X$allowed" = "X" ]; then ok=0; # something wrong with allowed list fi if [ "X$RFB_CLIENT_IP" != "X127.0.0.1" -o "X$RFB_SERVER_IP" != "X127.0.0.1" ]; then ok=0; # connection not over localhost fi if [ "$RFB_CLIENT_PORT" -le 0 -o "$RFB_SERVER_PORT" -le 0 ]; then ok=0; # something wrong with tcp port numbers fi if [ "$ok" = 0 ]; then echo "$0: invalid setting:" 1>&2 env | grep ^RFB | sort 1>&2 exit 1 fi # Linux netstat -nte: # Proto Recv-Q Send-Q Local Address Foreign Address State User Inode # 0 0 0 RFB_CLIENT RFB_SERVER ESTABLISHED nnnn .... # user=`netstat -nte | grep ESTABLISHED \ | grep " $RFB_CLIENT_IP:$RFB_CLIENT_PORT *$RFB_SERVER_IP:$RFB_SERVER_P ORT "` echo "netstat match: $user" 1>&2 user=`echo "$user" | head -n 1 | sed -e 's/^.*ESTABLISHED/ /' | awk '{print $1} '` ok=0 for u in $allowed do if [ "X$user" = "X$u" ]; then ok=1 break fi done if [ "X$ok" = "X1" ]; then echo "$0: user accepted: '$user'" 1>&2 exit 0 else echo "$0: user '$user' invalid:" 1>&2 echo "$0: allowed: $allowed" 1>&2 env | grep ^RFB | sort 1>&2 exit 1 fi ``` ### Q-39: Can I supply an external program to provide my own custom login method (e.g. Dynamic/One-time passwords or non-Unix (LDAP) usernames and passwords)? Yes, there are several possibilities. For background see the FAQ on the -accept where an external program may be run to decide if a VNC client should be allowed to try to connect and log in. If the program (or local user prompted by a popup) answers "yes", then -accept proceeds to the normal VNC and x11vnc authentication methods, otherwise the connection is dropped. To provide more direct coupling to the VNC client's username and/or supplied password the following options were added in Sep/2006: * -unixpw_cmd command * -passwdfile cmd:command * -passwdfile custom:command In each case "command" is an external command run by x11vnc. You supply it. For example, it may couple to your LDAP system or other servers you set up. For -unixpw_cmd the normal -unixpw Login: and Password: prompts are supplied to the VNC viewer and the strings the client returns are then piped into "command" as the first two lines of its standard input. If the command returns success, i.e. exit(0), the VNC client is accepted, otherwise it is rejected. For "-passwdfile cmd:command" the command is run and it returns a password list (like a password file, see the -passwdfile read:filename mode.) Perhaps a dynamic, one-time password is retrieved from a server this way. For "-passwdfile custom:command" one gets complete control over the VNC challenge-response dialog with the VNC client. x11vnc sends out a string of random bytes (16 by the VNC spec) and the client returns the same number of bytes in a way the server can verify only the authorized user could have created. The VNC protocol specifies DES encryption with a password. If you are willing to modify the VNC viewers, you can have it be anything you want, perhaps a less crackable MD5 hash scheme or one-time pad. Your program will read from its standard input the size of the challenge-response followed by a newline, then the challenge bytes followed by the response bytes. If your command then returns success, i.e. exit(0), the VNC client is accepted, otherwise it is rejected. In all cases the "RFB_*" environment variables are set as under -accept. These variables can provide useful information for the externally supplied program to use. ### Q-40: Why does x11vnc exit as soon as the VNC viewer disconnects? And why doesn't it allow more than one VNC viewer to connect at the same time? These defaults are simple safety measures to avoid someone unknowingly leaving his X11 desktop exposed (to the internet, say) for long periods of time. Use the -forever option (aka -many) to have x11vnc wait for more connections after the first client disconnects. Use the -shared option to have x11vnc allow multiple clients to connect simultaneously. Recommended additional safety measures include using ssh (see above), stunnel, -ssl, or a VPN to authenticate and encrypt the viewer connections or to at least use the -rfbauth passwd-file option to use VNC password protection (or -passwdfile) It is up to YOU to apply these security measures, they will not be done for you automatically. ### Q-41: Can I limit which machines incoming VNC clients can connect from? Yes, look at the -allow and -localhost options to limit connections by hostname or IP address. E.g. ``` x11vnc -allow 192.168.0.1,192.168.0.2 ``` for those two hosts or ``` x11vnc -allow 192.168.0. ``` for a subnet. For individual hosts you can use the hostname instead of the IP number, e.g.: "-allow snoopy", and "-allow darkstar,wombat". Note that -localhost achieves the same thing as "-allow 127.0.0.1" For more control, build libvncserver with libwrap support (tcp_wrappers) and then use /etc/hosts.allow See hosts_access(5) for complete details. ### Q-42: How do I build x11vnc/libvncserver with libwrap (tcp_wrappers) support? Here is one way to pass this information to the configure script: ``` env CPPFLAGS=-DUSE_LIBWRAP LDFLAGS=-lwrap ./configure ``` then run make as usual. This requires libwrap and its development package (tcpd.h) to be installed on the build machine. If additional CPPFLAGS or LDFLAGS options are needed supply them as well using quotes. The resulting x11vnc then uses libwrap/tcp_wrappers for connections. The service name you will use in /etc/hosts.allow and /etc/hosts.deny is "vnc", e.g.: ``` vnc: 192.168.100.3 .example.com ``` Note that if you run x11vnc out of inetd you do not need to build x11vnc with libwrap support because the /usr/sbin/tcpd reference in /etc/inetd.conf handles the tcp_wrappers stuff. ### Q-43: Can I have x11vnc only listen on one network interface (e.g. internal LAN) rather than having it listen on all network interfaces and relying on -allow to filter unwanted connections out? As of Mar/2005 there is the "-listen ipaddr" option that enables this. For ipaddr either supply the desired network interface's IP address (or use a hostname that resolves to it) or use the string "localhost". For additional filtering simultaneously use the "-allow host1,..." option to allow only specific hosts in. This option is useful if you want to insure that no one can even begin a dialog with x11vnc from untrusted network interfaces (e.g. ppp0.) The option -localhost now implies "-listen localhost" since that is what most people expect it to do. ### Q-44: Now that -localhost implies listening only on the loopback interface, how I can occasionally allow in a non-localhost via the -R allowonce remote control command? To do this specify "-allow localhost". Unlike -localhost this will leave x11vnc listening on all interfaces (but of course only allowing in local connections, e.g. ssh redirs.) Then you can later run "x11vnc -R allowonce:somehost" or use to gui to permit a one-shot connection from a remote host. ### Q-45: Can I fine tune what types of user input are allowed? E.g. have some users just be able to move the mouse, but not click or type anything? As of Feb/2005, the -input option allows you to do this. "K", "M", "B", "C", and "F" stand for Keystroke, Mouse-motion, Button-clicks, Clipboard, and File-Transfer, respectively. The setting: "-input M" makes attached viewers only able to move the mouse. "-input KMBC,M" lets normal clients do everything and enables view-only clients to move the mouse. These settings can also be applied on a per-viewer basis via the remote control mechanism or the GUI. E.g. x11vnc -R input:hostname:M ### Q-46: Can I prompt the user at the local X display whether the incoming VNC client should be accepted or not? Can I decide to make some clients view-only? How about running an arbitrary program to make the decisions? Yes, look at the "-accept command" option, it allows you to specify an external command that is run for each new client. (use quotes around the command if it contains spaces, etc.) If the external command returns 0 (success) the client is accepted, otherwise with any other return code the client is rejected. See below how to also accept clients view-only. The external command will have the RFB_CLIENT_IP environment variable set to the client's numerical IP address, RFB_CLIENT_PORT its port number. Similarly for RFB_SERVER_IP and RFB_SERVER_PORT to allow identification of the tcp virtual circuit. DISPLAY will be set to that of the X11 display being polled. Also, RFB_X11VNC_PID is set to the x11vnc process id (e.g. in case you decided to kill it), RFB_CLIENT_ID will be an id number, and RFB_CLIENT_COUNT the number of other clients currently connected. RFB_MODE will be "accept". Built-in Popup Window: As a special case, "-accept popup" will instruct x11vnc to create its own simple popup window. To accept the client press "y" or click mouse on the "Yes" button. To reject the client press "n" or click mouse on the "No" button. To accept the client View-only, press "v" or click mouse on the "View" button. If the -viewonly option has been supplied, the "View" action will not be present: the whole display is view only in that case. The popup window times out after 120 seconds, to change this behavior use "-accept popup:N" where N is the number of seconds (use 0 for no timeout.) More tricks: "-accept popupmouse" will only take mouse click responses, while "-accept popupkey" will only take keystroke responses (popup takes both.) After any of the 3 popup keywords you can supply a position of the window: +N+M, (the default is to center the window) e.g. -accept popupmouse+10+10. Also as a special case "-accept xmessage" will run the xmessage(1) program to prompt the user whether the client should be accepted or not. This requires that you have xmessage installed and available via PATH. In case it is not already on your system, the xmessage program is available at ftp://ftp.x.org/ (End of Built-in Popup Window:) To include view-only decisions for the external commands, prefix the command something like this: "yes:0,no:*,view:3 mycommand ..." This associates the three actions: yes(accept), no(reject), and view(accept-view-only), with the numerical return (i.e. exit()) codes. Use "*" instead of a number to set the default action (e.g. in case the external command returns an unexpected return code.) Here is an example -accept script called accept_or_lock. It uses xmessage and xlock (replace with your screen lock command, maybe it is "xscreensaver-command -lock", or kdesktop_lock, or "dtaction LockDisplay".) It will prompt the user at the X display whether to accept, reject, or accept view-only the client, but if the prompt times out after 60 seconds the screen is locked and the VNC client is accepted. This allows the remote access when no one is at the display. ``` #!/bin/sh # # accept_or_lock: prompt user at X display whether to accept an incoming # VNC connection. If timeout expires, screen is locked # and the VNC viewer is accepted (allows remote access # when no one is sitting at the display.) # # usage: x11vnc ... -forever -accept 'yes:0,no:*,view:4 accept_or_lock' # xmessage -buttons yes:2,no:3,view-only:4 -center \ -timeout 60 "x11vnc: accept connection from $RFB_CLIENT_IP?" rc=$? if [ $rc = 0 ]; then xlock & # or "xlock -mode blank" for no animations. sleep 5 exit 0 elif [ $rc = 2 ]; then exit 0 elif [ $rc = 4 ]; then exit 4 fi exit 1 ``` Stefan Radman has written a nice dtksh script dtVncPopup for use in CDE environments to do the same sort of thing. Information on how to use it is found at the top of the file. He encourages you to provide feedback to him to help improve the script. Note that in all cases x11vnc will block while the external command or popup is being run, so attached clients will not receive screen updates, etc during this period. To run a command when a client disconnects, use the "-gone command" option. This is for the user's convenience only: the return code of the command is not interpreted by x11vnc. The same environment variables are set as in "-accept command" (except that RFB_MODE will be "gone".) As of Jan/2006 the "-afteraccept command" option will run the command only after the VNC client has been accepted and authenticated. Like -gone the return code is not interpreted. RFB_MODE will be "afteraccept".) ### Q-47: I start x11vnc as root because it is launched via inetd(8) or a display manager like gdm(1). Can I have x11vnc later switch to a different user? As of Feb/2005 x11vnc has the -users option that allows things like this. Please read the documentation on it (also in the x11vnc -help output) carefully for features and caveats. It's use can often decrease security unless care is taken. BTW, a nice use of it is "-users +nobody" that switches to the Unix user nobody right after connections to the X display are established. In any event, while running x11vnc as root, remember it comes with no warranty ;-). ### Q-48: I use a screen-lock when I leave my workstation (e.g. xscreensaver or xlock.) When I remotely access my workstation desktop via x11vnc I can unlock the desktop fine, but I am worried people will see my activities on the physical monitor. What can I do to prevent this, or at least make it more difficult? Probably most work environments would respect your privacy if you powered off the monitor. Also remember if people have physical access to your workstation they basically can do anything they want with it (e.g. install a backdoor for later use, etc.) In any event, as of Jun/2004 there is an experimental utility to make it more difficult for nosey people to see your x11vnc activities. The source for it is blockdpy.c The idea behind it is simple (but obviously not bulletproof): when a VNC client attaches to x11vnc put the display monitor in the DPMS "off" state, if the DPMS state ever changes immediately start up the screen-lock program. The x11vnc user will notice something is happening and think about what to do next (while the screen is in a locked state.) This works (or at least has a chance of working) because if the intruder moves the mouse or presses a key on the keyboard, the monitor wakes up out of the DPMS off state, and this induces the screen lock program to activate as soon as possible. Of course there are cracks in this, the eavesdropper could detach your monitor and insert a non-DPMS one, and there are race conditions. As mentioned above this is not bulletproof. A really robust solution would likely require X server and perhaps even video hardware support. The blockdpy utility is launched by the -accept option and told to exit via the -gone option (the vnc client user should obviously re-lock the screen before disconnecting!) Instructions can be found in the source code for the utility at the above link. Roughly it is something like this: ``` x11vnc ... -accept "blockdpy -bg -f $HOME/.bdpy" -gone "touch $HOME/.bdpy" ``` but please read the top of the file. Update: As of Feb/2007 there is some builtin support for this: -forcedpms and -clientdpms however, they are probably less robust than the above blockdpy.c scheme, since if the person floods the physical machine with mouse or pointer input he can usually see flashes of the screen before the monitor is powered off again. See also the -grabkbd, -grabptr, and -grabalways options. ### Q-49: Can I have x11vnc automatically lock the screen when I disconnect the VNC viewer? Yes, a user mentions he uses the -gone option under CDE to run a screen lock program: ``` x11vnc -display :0 -forever -gone 'dtaction LockDisplay' ``` Other possibilities are: ``` x11vnc -display :0 -forever -gone 'xscreensaver-command -lock' x11vnc -display :0 -forever -gone 'kdesktop_lock' x11vnc -display :0 -forever -gone 'xlock &' x11vnc -display :0 -forever -gone 'xlock -mode blank &' ``` Here is a scheme using the -afteraccept option (in version 0.8) to unlock the screen after the first valid VNC login and to lock the screen after the last valid VNC login disconnects: ``` x11vnc -display :0 -forever -shared -afteraccept ./myxlocker -gone ./myxlocker ``` Where the script ./myxlocker is: ``` #!/bin/sh #/usr/bin/env | grep RFB_ | sort # for viewing RFB_* settings. if [ "X$RFB_MODE" = "Xafteraccept" ]; then if [ "X$RFB_STATE" = "XNORMAL" ]; then # require valid login if [ "X$RFB_CLIENT_COUNT" = "X1" ]; then killall xlock # Linux only. fi fi elif [ "X$RFB_MODE" = "Xgone" ]; then if [ "X$RFB_STATE" = "XNORMAL" ]; then # require valid login if [ "X$RFB_CLIENT_COUNT" = "X0" ]; then xlock -mode blank & fi fi fi ``` Note the xlock option "-mode blank" to avoid animations. There is a problem if you have x11vnc running this way in -forever mode and you hit Ctrl-C to stop it. The xlock (or other program) will get killed too. To work around this make a little script called setpgrp that looks like: ``` #!/usr/bin/perl setpgrp(0, 0); exec @ARGV; ``` then use -gone "setpgrp xlock &", etc. ## Encrypted Connections ### Q-50: How can I tunnel my connection to x11vnc via an encrypted SSH channel between two Unix machines? See the description earlier on this page on how to tunnel VNC via SSH from Unix to Unix. A number of ways are described along with some issues you may encounter. Other secure encrypted methods exists, e.g. stunnel, IPSEC, various VPNs, etc. See also the Enhanced TightVNC Viewer (SSVNC) page where much of this is now automated. ### Q-51: How can I tunnel my connection to x11vnc via an encrypted SSH channel from Windows using an SSH client like Putty? Above we described how to tunnel VNC via SSH from Unix to Unix, you may want to review it. To do this from Windows using Putty it would go something like this: * In the Putty dialog window under 'Session' enter the hostname or IP number of the Unix machine with display to be viewed. * Make sure the SSH protocol is selected and the server port is correct. * Under 'Connections/SSH/Tunnels' Add a Local connection with 'Source port: 5900' and 'Destination: localhost:5900' * Log into the remote machine by pressing 'Open' and supplying username, password, etc. * In that SSH shell, start up x11vnc by typing the command: x11vnc -display :0 plus any other desired options (e.g. -localhost.) * Finally, start up your VNC Viewer in Windows and enter 'localhost:0' as the VNC server. You can keep all of the settings in a Putty 'Saved Session'. Also, once everything is working, you can consider putting x11vnc -display :0 (plus other cmdline options) in the 'Remote command' Putty setting under 'Connections/SSH'. See also the Enhanced TightVNC Viewer (SSVNC) page where much of this is now automated via the Putty plink utility. For extra protection feel free to run x11vnc with the -localhost and -rfbauth/-passwdfile options. If the machine you SSH into via Putty is not the same machine with the X display you wish to view (e.g. your company provides incoming SSH access to a gateway machine), then you need to change the above Putty dialog setting to: 'Destination: otherhost:5900', Once logged in, you'll need to do a second login (ssh or rsh) to the workstation machine 'otherhost' and then start up x11vnc on it. This can also be automated by Chaining SSH's. As discussed above another option is to first start the VNC viewer in "listen" mode, and then launch x11vnc with the "-connect localhost" option to establish the reverse connection. In this case a Remote port redirection (not Local) is needed for port 5500 instead of 5900 (i.e. 'Source port: 5500' and 'Destination: localhost:5500' for a Remote connection.) ### Q-52: How can I tunnel my connection to x11vnc via an encrypted SSL channel using an external tool like stunnel? It is possible to use a "lighter weight" encryption setup than SSH or IPSEC. SSL tunnels such as stunnel (also stunnel.org) provide an encrypted channel without the need for Unix users, passwords, and key passphrases required for ssh (and at the other extreme SSL can also provide a complete signed certificate chain of trust.) On the other hand, since SSH is usually installed everywhere and firewalls often let its port through, ssh is frequently the path of least resistance (it also nicely manages public keys for you.) Update: As of Feb/2006 x11vnc has the options -ssl, -stunnel, and -sslverify to provide integrated SSL schemes. They are discussed in the Next FAQ (you probably want to skip to it now.) We include these non-built-in method descriptions below for historical reference. They are handy because can be used to create SSL tunnels to any VNC (or other type of) server. Here are some basic examples using stunnel but the general idea for any SSL tunnel utility is the same: * Start up x11vnc and constrain it to listen on localhost. * Then start up the SSL tunnel running on the same machine to forward incoming connections to that x11vnc. * Set up and run a similar SSL tunnel for the outgoing connection on the VNC viewer machine pointing it to the SSL/x11vnc server. * Optionally, set up server (or even client) public/private keys for use in authenticating one side to the other. * Finally, start the VNC Viewer and tell it to connect to the local port (e.g. a vnc display localhost:0) where its outgoing SSL tunnel is listening. We'll first use the stunnel version 3 syntax since it is the most concise and Unixy. Start up x11vnc listening on port 5900: ``` x11vnc -display :0 -rfbport 5900 -localhost -bg -passwdfile ~/mypass ``` Then start stunnel (version 3, not 4) with this command: ``` stunnel -d 5901 -r 5900 -p /path/to/stunnel.pem ``` The above two commands are run on host "far-away.east". The stunnel.pem is the self-signed PEM file certificate created when stunnel is built. One can also create certificates signed by Certificate Authorities or self-signed if desired using the x11vnc utilities described there. SSL Viewers: Next, on the VNC viewer side we need an SSL tunnel to encrypt the outgoing connection. The nice thing is any SSL tunnel can be used because the protocol is a standard. For this example we'll also use stunnel on the viewer side on Unix. First start up the client-side stunnel (version 3, not 4): ``` stunnel -c -d localhost:5902 -r far-away.east:5901 ``` Then point the viewer to the local tunnel on port 5902: ``` vncviewer -encodings "copyrect tight zrle hextile" localhost:2 ``` That's it. Note that the ss_vncviewer script can automate this easily, and so can the Enhanced TightVNC Viewer (SSVNC) package. Be sure to use a VNC password because unlike ssh by default the encrypted SSL channel provides no authentication (only privacy.) With some extra configuration one could also set up certificates to provide authentication of either or both sides as well (and hence avoid man-in-the-middle attacks.) See the stunnel and openssl documentation and also the key management section for details. stunnel has also been ported to Windows, and there are likely others to choose from for that OS. Much info for using it on Windows can be found at the stunnel site and in this article The article also shows the detailed steps to set up all the authentication certificates. (for both server and clients, see also the x11vnc utilities that do this.) The default Windows client setup (no certs) is simpler and only 4 files are needed in a folder: stunnel.exe, stunnel.conf, libssl32.dll, libeay32.dll. We used an stunnel.conf containing: ``` # stunnel.conf: client = yes options = ALL [myvncssl] accept = localhost:5902 connect = far-away.east:5901 ``` then double click on the stunnel.exe icon to launch it (followed by pointing the VNC viewer to localhost:2). stunnel inetd-like mode: As an aside, if you don't like the little "gap" of unencrypted TCP traffic (and a localhost listening socket) on the local machine between stunnel and x11vnc it can actually be closed by having stunnel start up x11vnc in -inetd mode: ``` stunnel -p /path/to/stunnel.pem -P none -d 5900 -l ./x11vnc_sh ``` Where the script x11vnc_sh starts up x11vnc: ``` #!/bin/sh x11vnc -q -inetd -display :0 -passwdfile ~/mypass ``` Note that this creates a separate x11vnc process for each incoming connection (as any inetd x11vnc usage would), but for the case of normally just one viewer at a time it should not be a big problem. stunnel 4 syntax: Somewhat sadly, the stunnel version 4 syntax is not so amenable to the command line or scripts. You need to create a config file with the parameters. E.g.: ``` stunnel x11vnc.cfg ``` Where the file x11vnc.cfg contains: ``` foreground = yes pid = cert = /path/to/stunnel.pem [x11vnc_stunnel] accept = 5901 connect = 5900 ``` One nice thing about version 4 is often the PEM file does not need to be specified because stunnel finds it in its installed area. One other gotcha the PEM file is usually only readable by root (it has the private key afterall), so you'll need to relax the permissions or make a copy that the user running x11vnc/stunnel can read. SSL VNC Viewers: Regarding VNC viewers that "natively" do SSL unfortunately there do not seem to be many. The SingleClick UltraVNC Java Viewer is SSL and is compatible with x11vnc's -ssl option and stunnel.) Commercial versions of VNC seem to have some SSL-like encryption built in, but we haven't tried those either and they probably wouldn't work since their (proprietary) SSL-like negotiation is likely embedded in the VNC protocol unlike our case where it is external. Note: as of Mar/2006 libvncserver/x11vnc provides a SSL-enabled Java applet that can be served up via the -httpdir or -http options when -ssl is enabled. It will also be served via HTTPS via either the VNC port (e.g. https://host:5900/) or a 2nd port via the -https option. In general current SSL VNC solutions are not particularly "seemless". But it can be done, and with a wrapper script on the viewer side and the -stunnel or -ssl option on the server side it works well and is convenient. Here is a simple script ss_vncviewer that automates running stunnel on the VNC viewer side on Unix a little more carefully than the commands printed above. (One could probably do a similar thing with a .BAT file on Windows in the stunnel folder.) Update Jul/2006: we now provide an Enhanced TightVNC Viewer (SSVNC) package that starts up STUNNEL automatically along with some other features. All binaries (stunnel, vncviewer, and some utilities) are provided in the package. It works on Unix, Mac OS X, and Windows. ### Q-53: Does x11vnc have built-in SSL tunneling? You can read about non-built-in methods in the Previous FAQ for background. SSL tunnels provide an encrypted channel without the need for Unix users, passwords, and key passphrases required for ssh (and at the other extreme SSL can also provide a complete signed certificate chain of trust.) On the other hand, since SSH is usually installed everywhere and firewalls often let its port through, ssh is frequently the path of least resistance. Built-in SSL x11vnc options: As of Feb/2006 the x11vnc -ssl option automates the SSL tunnel creation on the x11vnc server side. An SSL-enabled Java Viewer applet is also provided that can be served via HTTP or HTTPS to automate SSL on the client side. The -ssl mode uses the www.openssl.org library if available at build time. The mode requires an SSL certificate and key (i.e. .pem file.) These are usually created via the openssl(1) program (in fact in for "-ssl" (same as "-ssl SAVE") it will run openssl for you automatically.) So the SSL is not completely "built-in" since this external tool needs to be installed, but at least x11vnc runs it for you automatically. An -ssl example: ``` x11vnc -display :0 -ssl -passwdfile ~/mypass ``` You'll get output like this: ``` 09/04/2006 19:27:35 Creating a self-signed PEM certificate... 09/04/2006 19:27:35 ... The SSL VNC desktop is: far-away.east:0 PORT=5900 SSLPORT=5900 ``` In this case openssl(1) was used to create a PEM automatically. It will prompt you if you want to protect it with with a passphrase. Use "-ssl SAVE_NOPROMPT" to not be prompted. Use "-ssl TMP" to create a temporary self-signed cert that will be discarded when x11vnc exits. Update: As of Nov/2008 x11vnc also supports the VeNCrypt SSL/TLS tunnel extension to the VNC protocol. The older ANONTLS method (vino) is also supported. This support is on by default when the -ssl option is in use and can be fine-tuned using these options: -vencrypt, -anontls, and -sslonly. The normal x11vnc -ssl operation is somewhat like a URL method vncs://hostname if vnc://hostname indicates a standard unencrypted VNC connection. Just as https://hostname is an SSL encrypted version of http://hostname. The entire VNC session goes through the SSL tunnel. VeNCrypt, on the other hand, switches to SSL/TLS early in the VNC protocol handshake. x11vnc 0.9.6 supports both simultaneously when -ssl is active. Note: With the advent of OpenSSL 1.1.0, SSLv2 is dropped and SSLv3 deactivated per default. A couple broken ciphers have also gone, most importantly though is that clients trying to connect to x11vnc will now have to support TLS if encryption is to be used. You can of course always cook up your own build and run time OpenSSL 1.1.x if SSLv3 is absolutely required, but it isn't wise from a security point of view. SSL VNC Viewers:. Viewer-side will need to use SSL as well. See the next FAQ and here for SSL enabled VNC Viewers, including SSVNC, to connect to the above x11vnc via SSL. As seen above, the PEM (privacy enhanced mail) file does not need to be supplied if the openssl(1) command is available in PATH, in that case a self-signed, certificate good the current and subsequent x11vnc sessions is created (this may take a while on very slow machines.) In general, the PEM file contains both the Certificate (i.e. public key) and the Private Key. Because of the latter, the file should be protected from being read by untrusted users. The best way to do this is to encrypt the key with a passphrase (note however this requires supplying the passphrase each time x11vnc is started up.) See the discussion on x11vnc Key Management for some utilities provided for creating and managing certificates and keys and even for creating your own Certificate Authority (CA) for signing VNC server and client certificates. This may be done by importing the certificate into Web Browser or Java plugin keystores, or pointing stunnel to it. The wrapper script ss_vncviewer provides an example on unix (see the -verify option.) Here are some notes on the simpler default (non-CA) operation. To have x11vnc save the generated certificate and key, use the "SAVE" keyword like this: ``` x11vnc -ssl SAVE -display :0 ... ``` (this is the same as the default: "-ssl".) This way it will be saved in the default directory ~/.vnc/certs/ as server.crt (the certificate only) and server.pem (both certificate and private key.) This opens up the possibility of copying the server.crt to machines where the VNC Viewer will be run to enable authenticating the x11vnc SSL VNC server to the clients. When authentication takes place this way (or via the more sophisticated CA signing described here), then Man-In-The-Middle-Attacks are prevented. Otherwise, the SSL encryption only provides protection against passive network traffic "sniffing" (i.e. you are not protected against M-I-T-M attacks.) Nowadays, most people seem mostly concerned mainly about passive sniffing (and the default x11vnc SSL mode protects against it.) Note that there are hacker tools like dsniff/webmitm and cain that implement SSL Man-In-The-Middle attacks. They rely on the client not bothering to check the cert. One can test to some degree that SSL is working after starting x11vnc with the -stunnel or -ssl option. From another machine one can use the openssl command something like this: ``` openssl s_client -debug -msg -showcerts -connect far-away.east:5900 ``` After all of the debugging output and informational messages you'll see the string "RFB 003.008" that came from x11vnc. Pointing a web browser connecting to: https://far-away.east:5900/ and then viewing the SSL certificate information about the connection in the panels will also work. Note: If you serve up the SSL enabled Java VNC Viewer via something like: ``` x11vnc -ssl -httpdir /usr/local/share/x11vnc/classes/ssl ``` (or just the -http option), you can test it out completely using that, including using https to download it into the browser and connect to x11vnc. The older -stunnel option: Before the -ssl option there was a convenience option -stunnel that would start an external SSL tunnel for you using stunnel. The -ssl method is the preferred way, but for historical reference we keep the -stunnel info here. The -stunnel mode requires the stunnel.mirt.net command stunnel(8) to be installed on the system. Some -stunnel examples: ``` x11vnc -display :0 -stunnel /path/to/stunnel.pem -passwdfile ~/mypass x11vnc -display :0 -stunnel SAVE ... ``` You'll get output like this: ``` The VNC desktop is: localhost:50 The SSL VNC desktop is: far-away.east:0 PORT=5950 SSLPORT=5900 ``` That indicates stunnel is listening on port 5900 for incoming SSL-wrapped VNC connections from viewers. x11vnc is listening for local connections on port 5950 in this case (remote viewers cannot connect to it directly.) For -stunnel to work the stunnel command must be installed on the machine and available in PATH (note stunnel is often installed in sbin directories rather than bin.) Note that the default "-stunnel" by itself creates a temporary cert (as in "-ssl TMP".) ### Q-54: How do I use VNC Viewers with built-in SSL tunneling? Notes on using "native" VNC Viewers with SSL: There aren't any native VNC Viewers that do SSL (ask your VNC viewer developer to add the feature.) So a tunnel must be setup that you point the VNC Viewer to. This is often STUNNEL. You can do this manually, or use the ss_vncviewer script on Unix, or our Enhanced TightVNC Viewer (SSVNC) package on Unix, Windows, or MacOSX. See the next section for Java Web browser SSL VNC Viewers (you only need a Java-enabled Web browser for it to work.) Notes on the SSL enabled Java VNC Viewer provided in x11vnc classes/ssl/VncViewer.jar: A Java applet VNC Viewer allows you to connect to a VNC Server from a Java-enabled Web browser. The SSL enabled Java VNC Viewer (VncViewer.jar) in the x11vnc package supports only SSL based connections by default. As mentioned above the -httpdir can be used to specify the path to .../classes/ssl. A typical location might be /usr/local/share/x11vnc/classes/ssl. Or -http can be used to try to have it find the directory automatically. Also note that the SingleClick UltraVNC Java Viewer is compatible with x11vnc's -ssl SSL mode. (We tested it this way: "java -cp ./VncViewer.jar VncViewer HOST far-away.east PORT 5900 USESSL 1 TRUSTALL 1") The Java viewer uses SSL to communicate securely with x11vnc. Note that the applet can optionally also be downloaded into your web browser via HTTPS (which is HTTP over SSL.) This way the HTML page and the Java applet itself are also delivered securely with SSL (as opposed to only the VNC traffic being encrypted with SSL.) For this case the output will be something like this: ``` x11vnc -ssl SAVE -http ... The SSL VNC desktop is: far-away.east:0 Java SSL viewer URL: https://far-away.east:5900/ Java SSL viewer URL: http://far-away.east:5800/ PORT=5900 SSLPORT=5900 ``` Indicating the two URLs (the first one encrypted, the second not) one could point the web browser at to get the VNC viewer applet. E.g. put this ``` http://far-away.east:5800/ ``` or: ``` https://far-away.east:5900/ ``` into your Java-enabled Web browser. Note that KDE's Konqueror web browser seems to have problems with https Java applets, so you'll have to use the http/5800 with it (if you get https/5900 working let us know how you did it.) If you are using a router/firewall with port-redirection, and you are redirecting ports other than the default ones (5800, 5900) listed above see here. The https service provided thru the actual VNC port (5900 in the above example) can occasionally be slow or unreliable (it has to read some input and try to guess if the connection is VNC or HTTP.) If it is unreliable for you and you still want to serve the Java applet via https, use the -https option to get an additional port dedicated to https (its URL will also be printed in the output.) Another possibility is to add the GET applet parameter: ``` https://far-away.east:5900/?GET=1 ``` This will have the VNC Viewer send a special HTTP GET string "GET /request.https.vnc.connection HTTP/1.0" that x11vnc will notice more quickly as a request for a VNC connection. Otherwise it must wait for a timeout to expire before it assumes a VNC connection. You may also use "urlPrefix=somestring" to have /somestring prepended to /request.https.vnc.connection". Perhaps you are using a web server proxy scheme to enter a firewall or otherwise have rules applied to the URL. If you need to have any slashes "/" in "somestring" use "_2F_" (a deficiency in libvncserver prevents using the more natural "%2F".) You apply multiple applet parameters in the regular URL way, e.g.: ``` https://far-away.east:5900/?GET=1&urlPrefix=mysubdir&... ``` All of the x11vnc Java Viewer applet parameters are described in the file classes/ssl/README Tips on Getting the SSL Java Applet Working the First Time: Unfortunately, it can be a little tricky getting the SSL VNC Java Viewer working with x11vnc. Here are some tips to getting working the first time (afterwards you can incrementally customize with more complex settings.) * First try it on the LAN: Do NOT try to have it work the first time going through firewalls, Web proxies, home router port redirections, or Apache portal. Just try a direct connection over your LAN first (if you only have 1 machine and no LAN, just do a direct connection to the same machine: localhost.) If the LAN machine you run x11vnc on has its own host-level firewall (most linux machine come with that on by default), disable it or at least let tcp ports 5800-6000 through. * First try HTTP to download the Java Applet: x11vnc can serve both the Java Applet jar file and VNC out of the same port (both tunneled through SSL, see below.) But it can lead to timing and other problems. So first try HTTP instead of HTTPS to download the Applet jar file (VncViewer.jar.) That is to say try http://hostname:5800 in your web browser first before trying https://hostname:5900. x11vnc will print out the ports and URLs it is using, so use the HTTP one it prints out. * Always Restart the Browser: If you are having failures and have to repeatedly retry things ALWAYS restart the browser (i.e. completely exit it and then start a new browser process) each time. Otherwise as you are changing things the browser may "remember" failed applet downloads, etc. and just add to the confusion and irreproducibility. If you see it trying to download VncViewer.class (instead of VncViewer.jar) you know it is really confused and needs to be restarted. * Step Lively: If you get Browser or Java VM or VNC Viewer applet dialog boxes saying things like "Do you want to trust this certificate?" or "The hostname does not match the one on the certificate", etc. just go through them as quickly as possible. x11vnc cannot wait forever for each SSL connection, and so if you dawdle too long inspecting the certs, etc it can lead to problems. Get it working first before taking your time to read the details in the dialogs, etc. * No inetd, Please: Even if you intend to deploy via inetd or xinetd eventually, get that working later (and remember do not use something like "-ssl TMP" that creates a new temporary SSL certificate for every new socket connection.) * Nothing Fancy: Do not try fancy stuff like -svc, -create, -unixpw, "-users unixpw=", "-users sslpeer=", -sslverify, etc. Just get the simplest connection working first and then incrementally add what you need. So the recommended test command lines are: ``` x11vnc -ssl SAVE -http x11vnc -ssl SAVE -httpdir /path/to/x11vnc/classes/ssl ``` Use the latter if x11vnc cannot automatically find the classes/ssl directory (this what the -http option instructs it to do.) Then point your browser to the HTTP (not HTTPS) URL it prints out. Following the above guidelines, did it work? If so, Congratulations!! you created an SSL encrypted connection between the SSL Java applet running in your web browser and x11vnc. The fact that you used HTTP instead of HTTPS to download the applet is not the end of the world (some users do it this way), the main thing is that the VNC traffic is encrypted with SSL. If you are having trouble even with the above baseline test case feel free to contact me (please send the Full x11vnc output, not just part of it; the complete x11vnc command line; the URL(s) entered in the browser; the full Java Console output; and anything else you can think of.) Next, you can add the features you want one by one testing it still works each time. I suggest first turning on the HTTPS applet download (https://hostname:5900) if that is what you intend to use. That one gives the most trouble because of the ambiguity of passing two different protocols (HTTP and VNC) through the same SSL service port. Next, turn on inetd if you intend to use that (this can be tricky too, be sure to use -oa logfile and inspect it carefully if there are problems.) If you are going to use non-standard ports (e.g. "-rfbport 443" as root), work on that next. Then enable the firewall, router port redirection channel (you will somehow need to be outside to do that, maybe test that through another VNC session.) Then, if you plan to use them, enable "fancy stuff" like "-svc" or "-unixpw", etc, etc. Be sure to add a password either "-rfbauth" or "-unixpw" or both. If you need to have the web browser use a corporate Web Proxy (i.e. it cannot connect directly) work on that last. Ditto for the Apache portal. Router/Firewall port redirs: If you are doing port redirection at your router to an internal machine running x11vnc AND the internet facing port is different from the internal machine's VNC port, you will need to apply the PORT applet parameter to indicate to the applet the Internet facing port number (otherwise by default the internal machine's port, say 5900, is sent and that of course is rejected at the firewall/router.) For example: ``` https://far-away.east:443/?GET=1&PORT=443 ``` So in this example the user configures his router to redirect connections to port 443 on his Internet side to, say, port 5900 on the internal machine running x11vnc. See also the -httpsredir option that will try to automate this for you. To configure your router to do port redirection, see its instructions. Typically, from the inside you point a web browser to a special URL (e.g. http://192.168.1.1) and you get a web interface to configure it. Look for something like "Port Redirection" or "Port Forwarding", probably under "Advanced" or something like that. If you have a Linux or Unix system acting as your firewall/router, see its firewall configuration. You can also use x11vnc options -rfbport NNNNN and -httpport NNNNN to match the ports that your firewall will be redirecting to the machine where x11vnc is run. Tedious Dialogs: If you do serve the SSL enabled Java viewer via https be prepared for quite a number of "are you sure you trust this site?" dialogs: * First from the Web browser that cannot verify the self-signed certificate when it downloads index.vnc. * From the Web browser again noting that the common name on the certificate does not match the hostname of the remote machine. * Next from the Java VM that cannot verify the self-signed certificate when it downloads VncViewer.jar. * And also from the Java VM again noting that the common name on the certificate does not match the hostname of the remote machine. * Finally from the Java VncViewer applet itself saying it cannot verify the certificate! (or a popup asking you if you want to see the certificate.) Note that sometimes if you pause too long at one of the above dialogs then x11vnc may exceed a timeout and assume the current socket connection is VNC instead of the HTTPS it actually is (but since you have paused too long at the dialog the GET request comes too late.) Often hitting Reload and going through the dialogs more quickly will let you connect. The Java VM dialogs are the most important ones to NOT linger at. If you see in the x11vnc output a request for VncViewer.class instead of VncViewer.jar it is too late... you will need to completely restart the Web browser to get it to try for the jar again. You can use the -https option if you want a dedicated port for HTTPS connections instead of sharing the VNC port. To see example x11vnc output for a successful https://host:5900/ connection with the Java Applet see This Page. And here is a newer example including the Java Console output. All of the x11vnc Java Viewer applet parameters are described in the file classes/ssl/README Notes on the VNC Viewer ss_vncviewer wrapper script: If you want to use a native VNC Viewer with the SSL enabled x11vnc you will need to run an external SSL tunnel on the Viewer side. There do not seem to be any native SSL VNC Viewers outside of our x11vnc and SSVNC packages. The basic ideas of doing this were discussed for external tunnel utilities here. The ss_vncviewer script provided with x11vnc and SSVNC can set up the stunnel tunnel automatically on unix as long as the stunnel command is installed on the Viewer machine and available in PATH (and vncviewer too of course.) Note that on a Debian based system you will need to install the package stunnel4 not stunnel. You can set the environment variables STUNNEL and VNCVIEWERCMD to point to the correct programs if you want to override the defaults. Here are some examples: ``` 1) ss_vncviewer far-away.east:0 2) ss_vncviewer far-away.east:0 -encodings "copyrect tight zrle hextile" 3) ss_vncviewer -verify ./server.crt far-away.east:0 4) ss_vncviewer -mycert ./client.pem far-away.east:0 5) ss_vncviewer -proxy far-away.east:8080 myworkstation:0 ``` The first one is the default mode and accepts the x11vnc certificate without question. The second one is as the first, but adds the -encodings options to the vncviewer command line. The third one requires that the x11vnc server authenticate itself to the client against the certificate in the file ./server.crt (e.g. one created by "x11vnc -ssl SAVE" and safely copied to the VNC viewer machine.) The fourth one is for VNC Viewer authentication, it uses ./client.pem to authenticate itself to x11vnc. One can supply both -verify and -mycert simultaneously. The fifth one shows that Web proxies can be used if that is the only way to get out of the firewall. If the "double proxy" situation arises separate the two by commas. See this page for more information on how Web proxies come into play. If one uses a Certificate Authority (CA) scheme described here, the wrapper script would use the CA cert instead of the server cert: ``` 3') ss_vncviewer -verify ./cacert.crt far-away.east:0 ``` Update Jul/2006: we now provide an Enhanced TightVNC Viewer (SSVNC) package that starts up STUNNEL automatically along with some other features. All binaries (stunnel, vncviewer, and some utilities) are provided in the package. It works on Unix, Mac OS X, and Windows. ### Q-55: How do I use the Java applet VNC Viewer with built-in SSL tunneling when going through a Web Proxy? The SSL enabled Java VNC Viewer and firewall Proxies: SSL and HTTPS aside, there is a general problem with Firewall Proxies and Java Applets that open sockets. The applet is downloaded successfully (through the browser) using HTTP and the proxy, but when the applet tries to reconnect to the originating host (the only one allowed by security) it does not use the proxy channel. So it cannot reconnect to the server the applet came from! We have found a convenient workaround: in the directory where VncViewer.jar resides there is a digitally signed version of the same applet called SignedVncViewer.jar. Since the applet is digitally signed, there will be an additional dialog from the Java VM plugin asking you if you want to trust the applet fully. You should say "Yes". If you do, the applet will be run in a mode where it can try to determine the firewall proxy host name and port (it will ask you for them if it cannot find them.) This way it can connect directly to the Proxy and then request the CONNECT method to be redirected to the originating host (the x11vnc VNC Server.) SSL is then layered over this socket. To do this you should use the proxy.vnc HTML file like via this URL in your browser: ``` https://yourmachine.com:5900/proxy.vnc ``` (instead of the unsigned one in https://yourmachine.com:5900/ that gives the default index.vnc) Proxies that limit CONNECT to ports 443 and 563: Things become trickier if the Web proxy restricts which CONNECT ports can be redirected to. For security, some (most?) proxies only allow port 443 (HTTPS) and 563 (SNEWS) by default. In this case, the only thing to do is run x11vnc on that low port, e.g. "-rfbport 443", (or use a port redirection on, say, a firewall or router port 443 to the internal machine.) If you do such a redirection to an internal machine and x11vnc is not listening on port 443, you will probably need to edit proxy.vnc. Suppose the SSL x11vnc server was listening on port 5901. You should change the line in proxy.vnc from: ``` ``` to: ``` ``` Since otherwise $PORT will be expanded to 5901 by x11vnc and the viewer applet will fail to connect to that port on the firewall. Another way to achieve the same thing is to use the applet PORT parameter: ``` https://yourmachine.com/proxy.vnc?PORT=443 ``` this is cleaner because it avoids editing the file, but requires more parameters in the URL. See also the -httpsredir x11vnc option that will try to automate this for you. To use the GET trick discussed above, do: ``` https://yourmachine.com/proxy.vnc?GET=1&PORT=443 ``` All of the x11vnc Java Viewer applet parameters are described in the file classes/ssl/README Here is an example of Java Console and x11vnc output for the Web proxy case. Note that both the ss_vncviewer stunnel Unix wrapper script and Enhanced TightVNC Viewer (SSVNC) can use Web proxies as well even though they do not involve a Web browser. ### Q-56: Can Apache web server act as a gateway for users to connect via SSL from the Internet with a Web browser to x11vnc running on their workstations behind a firewall? Yes. You will need to configure apache to forward these connections. It is discussed here. This SSL VNC portal provides a clean alternative to the traditional method where the user uses SSH to log in through the gateway to create the encrypted port redirection to x11vnc running on her desktop. Also see the desktop.cgi CGI script method that achieves much of what this Apache VNC SSL portal method does (as long as desktop.cgi's 'port redirection' mode is enabled.) ### Q-57: Can I create and use my own SSL Certificate Authority (CA) with x11vnc? Yes, see this page for how to do this and the utility commands x11vnc provides to create and manage many types of certificates and private keys. ## Display Managers and Services ### Q-58: How can I run x11vnc as a "service" that is always available? There are a number of ways to do this. The primary thing you need to decide is whether you want x11vnc to connect to the X session on the machine 1) regardless of who (or if anyone) has the X session, or 2) only if a certain user has the X session. Because X sessions are protected by X permissions (MIT-MAGIC-COOKIE files XAUTHORITY and $HOME/.Xauthority) the automatically started x11vnc will of course need to have sufficient permissions to connect to the X display. Here are some ideas: * Use the description under "Continuously" in the FAQ on x11vnc and Display Managers * Use the description in the FAQ on x11vnc and inetd(8) * Use the description in the FAQ on Unix user logins and inetd(8) * Start x11vnc from your $HOME/.xsession (or $HOME/.xinitrc or autostart script or ...) * Although less reliable, see the x11vnc_loop rc.local hack below. The display manager scheme will not be specific to which user has the X session unless a test is specifically put into the display startup script (often named Xsetup.) The inetd(8) scheme may or may not be specific to which user has the X session (and it may not be able to do all users via the XAUTHORITY permission issues.) The .xsession/.xinitrc scheme is obviously is specific to a particular user and only when they are logged into X. If you do not know what a $HOME/.xsession script is or how to use one, perhaps your desktop has a "session startup commands" configuration option. The command to be run in the .xsession or .xinitrc file may look like this: ``` x11vnc -logfile $HOME/.x11vnc.log -rfbauth $HOME/.vnc/passwd -forever -bg ``` plus any other options you desire. Depending on your desktop and/or OS/distribution the automatically run X startup scripts (traditionally .xsession/.xinitrc) may have to be in a different directory or have a different basename. One user recommends the description under 'Running Scripts Automatically' at this link. Firewalls: note all methods will require the host-level firewall to be configured to allow connections in on a port. E.g. 5900 (default VNC port) or 22 (default SSH port for tunnelling VNC.) Most systems these days have firewalls turned on by default, so you will actively have to do something to poke a hole in the firewall at the desired port number. See your system administration tool for Firewall settings (Yast, Firestarter, etc.) ### Q-59: How can I use x11vnc to connect to an X login screen like xdm, GNOME gdm, KDE kdm, or CDE dtlogin? (i.e. nobody is logged into an X session yet.) We describe two scenarios here. The first is called 'One time only' meaning you just need to do it quickly once and don't want to repeat; and the second is called 'Continuously' meaning you want the access to be available after every reboot and after every desktop logout. --- One time only: If the X login screen is running and you just want to connect to it once (i.e. a one-shot): It is usually possible to do this by just adjusting the XAUTHORITY environment variable to point to the correct MIT-COOKIE auth file while running x11vnc as root, e.g. for the gnome display manager, GDM: ``` x11vnc -auth /var/gdm/:0.Xauth -display :0 ``` (the -auth option sets the XAUTHORITY variable for you.) There will be a similar thing to do for xdm using however a different auth directory path (perhaps something like /var/lib/xdm/authdir/authfiles/A:0-XQvaJk) for the xdm greeter or /var/lib/kdm/A:0-crWk72 (or /var/run/xauth/A:0-qQPftr, etc. etc) for the kdm greeter. Of course, the random characters in the file basename will vary and you will need to use the actual filename on your system. Read your system docs to find out where the display manager cookie files are kept. Trick: sometimes ps(1) can reveal the X server process -auth argument (e.g. "ps wwaux | grep auth") and hence the path to the auth file. x11vnc must be run as root for this because the /var/gdm/:0.Xauth, /var/lib/kdm/A:0-crWk72, etc. auth files are only readable by root. If you do not want to run x11vnc as root, you can copy (as root or sudo) the auth file to some location and make it readable by your userid. Then run x11vnc as your userid with -auth pointed to the copied file. Update Dec/2009: use "-auth guess" to have x11vnc try to guess the location of the auth file for you. You next connect to x11vnc with a VNC viewer, give your username and password to the X login prompt to start your session. Note: GDM: gdm seems to have an annoying setting that causes x11vnc (and any other X clients) to be killed after the user logs in. Setting KillInitClients=false in the [daemon] section of /etc/X11/gdm/gdm.conf (or /etc/gdm/gdm.conf, etc.) avoids this. Otherwise, just restart x11vnc and then reconnect your viewer. Other display managers (kdm, etc) may also have a similar problem. One user reports having to alter "gdm.conf-custom" as well. Note: Solaris: For dtlogin in addition to the above sort of trick (BTW, the auth file should be in /var/dt), you'll also need to add something like Dtlogin*grabServer:False to the Xconfig file (/etc/dt/config/Xconfig or /usr/dt/config/Xconfig on Solaris, see the example at the end of this FAQ.) Then restart dtlogin, e.g.: /etc/init.d/dtlogin stop; /etc/init.d/dtlogin start or reboot. Update Nov/2008: Regarding GDM KillInitClients: see the -reopen option for another possible workaround. Update Oct/2009: Regarding GDM KillInitClients: starting with x11vnc 0.9.9 it will try to apply heuristics to detect if a window manager is not running (i.e. whether the Display Manager Greeter Login panel is still up.) If it thinks the display manager login is still up it will delay creating windows or using XFIXES. The former is what GDM uses to kill the initial clients, use of the latter can cause a different problem: an Xorg server crash. So with 0.9.9 and later it should all work without needing to set KillInitClients=false (which is a good because recent GDM, v2.24, has removed this option) or use -noxfixes. To disable the heuristics and delaying set X11VNC_AVOID_WINDOWS=never; to set the delay time explicitly use, e.g., X11VNC_AVOID_WINDOWS=120 (delays for 120 seconds after the VNC connection; you have that long to log in.) Continuously: Have x11vnc reattach each time the X server is restarted (i.e. after each logout and reboot): To make x11vnc always attached to the X server including the login screen you will need to add a command to a display manager startup script. Please consider the security implications of this! The VNC display for the X session always accessible (but hopefully password protected.) Add -localhost if you only plan to access via a SSH tunnel. The name of the display manager startup script file depends on desktop used and seem to be: ``` GDM (GNOME) /etc/X11/gdm/Init/Default /etc/gdm/Init/Default KDM (KDE) /etc/kde*/kdm/Xsetup XDM /etc/X11/xdm/Xsetup (or sometimes xdm/Xsetup_0) CDE /etc/dt/config/Xsetup ``` although the exact location can be operating system, distribution, and time dependent. See the documentation for your display manager: gdm(1), kdm(1), xdm(1), dtlogin(1) for additional details. There may also be display number specific scripts: e.g. Xsetup_0 vs. Xsetup, you need to watch out for. Note: You should read and understand all of the Note's and Update's in the 'One time only' section above. All of the GDM topics apply here as well: Note: GDM: The above (in 'One time only') gdm setting of KillInitClients=false in /etc/X11/gdm/gdm.conf (or /etc/gdm/gdm.conf, etc.) for GDM is needed here as well. Other display managers (KDM, etc) may also have a similar problem. Also see the Update Oct/2009 above where x11vnc 0.9.9 and later automatically avoids being killed. Note: DtLogin: The above (in 'One time only') Dtlogin*grabServer:False step for Solaris will be needed for dtlogin here as well. In any event, the line you will add to the display manager script (Xsetup, Default, or whatever) will look something like: ``` /usr/local/bin/x11vnc -rfbauth /path/to/the/vnc/passwd -o /var/log/x11vnc.log -forever -bg ``` where you should customize the exact command to your needs (e.g. -localhost for SSH tunnel-only access; -ssl SAVE for SSL access; etc.) Happy, happy, joy, joy: Note that we do not need to specify -display or -auth because happily they are already set for us in the DISPLAY and XAUTHORITY environment variables for the Xsetup script!!! You may also want to force the VNC port with something like "-rfbport 5900" (or -N) to avoid autoselecting one if 5900 is already taken. Fedora/gdm: Here is an example of what we did on a vanilla install of Fedora-C3 (seems to use gdm by default.) Add a line like this to /etc/X11/gdm/Init/:0 ``` /usr/local/bin/x11vnc -rfbauth /etc/x11vnc.passwd -forever -bg -o /var/log/x11vnc.log ``` And then add this line to /etc/X11/gdm/gdm.conf (or /etc/gdm/gdm.conf, etc.) in the [daemon] section: ``` KillInitClients=false ``` Then restart: /usr/sbin/gdm-restart (or reboot.) The KillInitClients=false setting is important: without it x11vnc will be killed immediately after the user logs in. Here are full details on how to configure gdm --- Solaris/dtlogin: Here is an example of what we did on a vanilla install of Solaris: Make the directory /etc/dt/config: ``` mkdir -p /etc/dt/config ``` Copy over the Xconfig file for customization: ``` cp /usr/dt/config/Xconfig /etc/dt/config/Xconfig ``` Edit /etc/dt/config/Xconfig and uncomment the line: ``` Dtlogin*grabServer: False ``` Next, copy over Xsetup for customization: ``` cp /usr/dt/config/Xsetup /etc/dt/config/Xsetup ``` Edit /etc/dt/config/Xsetup and at the bottom put a line like: ``` /usr/local/bin/x11vnc -forever -o /var/log/x11vnc.log -bg ``` (tweaked to your local setup and preferences, a password via -rfbauth, etc. would be a very good idea.) Restart the X server and dtlogin: ``` /etc/init.d/dtlogin stop /etc/init.d/dtlogin start ``` (or reboot or maybe just restart the X session.) --- KDM: One user running the kdm display manager reports putting this line: ``` x11vnc -forever -rfbauth /home/xyz/.vnc/passwd -bg -o /var/log/x11vnc.log ``` in /etc/kde/kdm/Xsetup. After rebooting the system it all seemed to work fine. --- If you do not want to deal with any display manager startup scripts, here is a kludgey script that can be run manually or out of a boot file like rc.local: x11vnc_loop It will need some local customization before running. Because the XAUTHORITY auth file must be guessed by this script, use of the display manager script method described above is greatly preferred. There is also the -loop option that does something similar. If the machine is a traditional Xterminal you may want to read this FAQ. Firewalls: note all methods will require the host-level firewall to be configured to allow connections in on a port. E.g. 5900 (default VNC port) or 22 (default SSH port for tunnelling VNC.) Most systems these days have firewalls turned on by default, so you will actively have to do something to poke a hole in the firewall at the desired port number. See your system administration tool for Firewall settings (Yast, Firestarter, etc.) ### Q-60: Can I run x11vnc out of inetd(8)? How about xinetd(8)? Yes, perhaps a line something like this in /etc/inetd.conf will do it for you: ``` 5900 stream tcp nowait root /usr/sbin/tcpd /usr/local/bin/x11vnc_sh ``` where the shell script /usr/local/bin/x11vnc_sh uses the -inetd option and looks something like (you'll need to customize to your settings.) ``` #!/bin/sh /usr/local/bin/x11vnc -inetd -display :0 -auth /home/fred/.Xauthority \ -rfbauth /home/fred/.vnc/passwd -o /var/log/x11vnc_sh.log ``` Important: Note that you must redirect the standard error output to a log file (e.g. -o logfile) or "2>/dev/null" for proper operation via inetd (otherwise the standard error also goes to the VNC vncviewer, and that confuses it greatly, causing it to abort.) If you do not use a wrapper script as above but rather call x11vnc directly in /etc/inetd.conf and do not redirect stderr to a file, then you must specify the -q (aka -quiet) option: "/usr/local/bin/x11vnc -q -inetd ...". When you supply both -q and -inet and no "-o logfile" then stderr will automatically be closed (to prevent, e.g. library stderr messages leaking out to the viewer.) The recommended practice is to use "-o logfile" to collect the output in a file or wrapper script with "2>logfile" redirection because the errors and warnings printed out are very useful in troubleshooting problems. Note also the need to set XAUTHORITY via -auth to point to the MIT-COOKIE auth file to get permission to connect to the X display (setting and exporting the XAUTHORITY variable accomplishes the same thing.) See the x11vnc_loop file in the previous question for more ideas on what that auth file may be, etc. The scheme described in the FAQ on Unix user logins and inetd(8) works around the XAUTHORITY issue nicely. Note: On Solaris you cannot have the bare number 5900 in /etc/inetd.conf, you'll need to replace it with a word like x11vnc an then put something like "x11vnc 5900/tcp" in /etc/services. Since the process runs as root, it might be a bad idea to have the logfile in a world-writable area like /tmp if there are untrustworthy users on the machine. Perhaps /var/log is a better place. Be sure to look at your /etc/hosts.allow and /etc/hosts.deny settings to limit the machines that can connect to this service (your desktop!) For the above example with /etc/hosts.allow: ``` x11vnc_sh : 123.45.67.89 ``` A really safe way to do things is to limit the above inetd to localhost only (via /etc/hosts.allow) and use ssh to tunnel the incoming connection. Using inetd for this prevents there being a tiny window of opportunity between x11vnc starting up and your vncviewer connecting to it. Always use a VNC password to further protect against unwanted access. For xinetd(8), one user reports he created the file /etc/xinetd.d/x11vncservice containing the following: ``` # default: off # description: service x11vncservice { flags = REUSE NAMEINARGS port = 5900 type = UNLISTED socket_type = stream protocol = tcp wait = no user = root server = /usr/sbin/tcpd server_args = /usr/local/bin/x11vnc_sh disable = no } ``` With the contents of /usr/local/bin/x11vnc_sh similar to the example given above. One user reports this works with avoiding the wrapper script: ``` service x11vncservice { port = 5900 type = UNLISTED socket_type = stream protocol = tcp wait = no user = root server = /usr/local/bin/x11vnc server_args = -inetd -q -display :0 -auth /var/gdm/:0.Xauth disable = no } ``` (or one can replace the -q with say "-o /var/log/x11vnc.log" to capture a log) The above works nicely for GDM because the -auth file is a fixed name. For KDM or XDM the filename varies. Here is one idea for a x11vnc_sh wrapper to try to guess the name: ``` #!/bin/sh COLUMNS=256 export COLUMNS authfile=`ps wwaux | grep '/X.*-auth' | grep -v grep | sed -e 's/^.*-auth *//' -e 's/ .*$//' | head -n 1` if [ -r "$authfile" ]; then exec /usr/local/bin/x11vnc -inetd -o /var/log/x11vnc.log -display :0 -a uth "$authfile" fi exit 1 ``` Starting with x11vnc 0.9.3 this can be automated by: ``` #!/bin/sh exec /usr/local/bin/x11vnc -inetd -o /var/log/x11vnc.log -find -env FD_XDM=1 ``` ### Q-61: Can I have x11vnc advertise its VNC service and port via mDNS/Zeroconf (e.g. Avahi) so VNC viewers on the local network can detect it automatically? Yes, as of Feb/2007 x11vnc supports mDNS / Zeroconf advertising of its service via the Avahi client library. Use the option -avahi (same as -mdns or -zeroconf) to enable it. Depending on your setup you may need to install Avahi (including the development/build packages), enable the server: avahi-daemon and avahi-dnsconfd, and possibly open up UDP port 5353 on your firewall. If the Avahi client library or build environment is not available at build-time, then at run-time x11vnc will try to look for external helper programs, avahi-browse(1) or dns-sd(1), to do the work. The service was tested with Chicken of the VNC ("Use Bonjour" selected) on a Mac on the same network and the service was noted and listed in the servers list. Clicking on it and then "Connect" connected automatically w/o having to enter any hostnames or port numbers. It appears SuSE 10.1 comes with avahi (or you can add packages, e.g. avahi-0.6.5-27) but not the development package (you can use the OpenSuSE avahi-devel rpm.) Unfortunately, you may need to disable another Zeroconf daemon "/etc/init.d/mdnsd stop", before doing "/etc/init.d/avahi-daemon start" and "/etc/init.d/avahi-dnsconfd start". We also had to comment out the browse-domains line in /etc/avahi/avahi-daemon.conf. Hopefully there is "LessConf" to do on other distros/OS's... ### Q-62: Can I have x11vnc allow a user to log in with her UNIX username and password and then have it find her X session display on that machine and then attach to it? How about starting an X session if one cannot be found? The easiest way to do this is via inetd(8) using the -unixpw and -display WAIT options. The reason inetd(8) makes this easier is that it starts a new x11vnc process for each new user connection. Otherwise a wrapper would have to listen for connections and spawn new x11vnc's (see this example and also the -loopbg option.) inetd(8) is not required for this, but it makes some aspects more general. Also with inetd(8) users always connect to a fixed VNC display, say hostname:0, and do not need to memorize a special VNC display number just for their personal use, etc. Update: Use the -find, -create, -svc, and -xdmsvc options that are shorthand for common FINDCREATEDISPLAY usage modes (e.g. terminal services) described below. (i.e. simply use "-svc" instead of the cumbersome "-display WAIT:cmd=FINDCREATEDISPLAY-Xvfb -unixpw -users unixpw= -ssl SAVE") The -display WAIT option makes x11vnc wait until a VNC viewer is connected before attaching to the X display. Additionally it can be used to run an external command that returns the DISPLAY and XAUTHORITY data. We provide some useful builtin ones (FINDDISPLAY and FINDCREATEDISPLAY below), but in principle one could supply his own script: "-display WAIT:cmd=/path/to/find_display" where the script find_display might look something like this. A default script somewhat like the above is used under "-display WAIT:cmd=FINDDISPLAY" (same as -find) The format for any such command is that it returns DISPLAY=:disp as the first line and any remaining lines are either XAUTHORITY=file or raw xauth data (the above example does the latter.) If applicable (-unixpw mode), the program is run as the Unix user name who logged in. On Linux if the virtual terminal is known the program appends ",VT=n" to the DISPLAY line; a chvt n will be attempted automatically. Or if only the X server process ID is known it appends ",XPID=n" (a chvt will be attempted by x11vnc.) Tip: Note that the -find option is an alias for "-display WAIT:cmd=FINDDISPLAY". Use it! The -unixpw option allows UNIX password logins. It conveniently knows the Unix username whose X display should be found. Here are a couple /etc/inetd.conf examples of this usage: ``` 5900 stream tcp nowait nobody /usr/sbin/tcpd /usr/local/bin/x11vnc -inetd -unixpw \ -find -o /var/log/x11vnc.log -ssl SAVE -ssldir /usr/local/certs 5900 stream tcp nowait root /usr/sbin/tcpd /usr/local/bin/x11vnc -inetd -unixpw \ -find -o /var/log/x11vnc.log -ssl SAVE -users unixpw= ``` Note we have used the -find alias and the very long lines have been split. An alternative is to use a wrapper script, e.g. /usr/local/bin/x11vnc.sh that has all of the options. (see also the -svc alias.) In the first inetd line x11vnc is run as user "nobody" and stays user nobody during the whole session. The permissions of the log files and certs directory will need to be set up to allow "nobody" to use them. In the second one x11vnc is run as root and switches to the user that logs in due to the "-users unixpw=" option. Note that SSL is required for this mode because otherwise the Unix password would be passed in clear text over the network. In general -unixpw is not required for this sort of scheme, but it is convenient because it determines exactly who the Unix user is whose display should be sought. Otherwise the find_display script would have to use some method to work out DISPLAY, XAUTHORITY, etc (perhaps you use multiple inetd ports and hardwire usernames for different ports.) If you really want to disable the SSL or SSH -localhost constraints (this is not recommended unless you really know what you are doing: Unix passwords sent in clear text is a very bad idea...) read the -unixpw documentation. A inetd(8) scheme for a fixed user that doesn't use SSL or unix passwds could be: ``` /usr/local/bin/x11vnc -inetd -users =fred -find -rfbauth /home/fred/.vnc/pass wd -o /var/log/x11vnc.log ``` The "-users =fred" option will cause x11vnc to switch to user fred and then find his X display. The VNC password (-rfbauth) as opposed to Unix password (-unixpw) is used to authenticate the VNC client. Similar looking commands to the above examples can be run directly and do not use inetd (just remove the -inetd option and run from the cmdline, etc.) X Session Creation: An added (Nov/2006) extension to FINDDISPLAY is FINDCREATEDISPLAY where if it does not find an X display via the FINDDISPLAY method it will create an X server session for the user (i.e. desktop/terminal server.) This is the only time x11vnc actually tries to start up an X server (normally it just attaches to an existing one.) For virtual sessions you will need to install the Xvfb program (e.g. apt-get install xvfb) or our Xdummy program (see below.) By default it will only try to start up virtual (non-hardware) X servers: first Xvfb and if that is not available then Xdummy (included in the x11vnc source code.) Note that Xdummy only works on Linux whereas Xvfb works just about everywhere (and in some situations Xdummy must be run as root.) An advantage of Xdummy over Xvfb is that Xdummy supports RANDR dynamic screen resizing, which can be handy if the user accesses the desktop from different sized screens (e.g. workstation and laptop.) So an inetd(8) example might look like: ``` 5900 stream tcp nowait root /usr/sbin/tcpd /usr/local/bin/x11vnc -inetd \ -o /var/log/x11vnc.log -http -prog /usr/local/bin/x11vnc \ -ssl SAVE -unixpw -users unixpw= -display WAIT:cmd=FINDCREATEDISPLAY ``` Where the very long lines have been split. See below where that long and cumbersome last line is replaced by the -svc alias. The above mode will allow direct SSL (e.g. ss_vncviewer or SSVNC) access and also Java Web browers access via: https://hostname:5900/. Tip: Note that the -create option is an alias for "-display WAIT:cmd=FINDCREATEDISPLAY-Xvfb". Tip: Note that -svc is a short hand for the long "-ssl SAVE -unixpw -users unixpw= -display WAIT:cmd=FINDCREATEDISPLAY" part. Unlike -create, this alias also sets up SSL encryption and Unix password login. The above inetd example then simplifies to: ``` 5900 stream tcp nowait root /usr/sbin/tcpd /usr/local/bin/x11vnc -inetd \ -o /var/log/x11vnc.log -http -prog /usr/local/bin/x11vnc \ -svc ``` Tip: In addition to the usual unixpw parameters, inside the VNC viewer the user can specify after his username (following a ":" see -display WAIT for details) for FINDCREATEDISPLAY they can add "geom=WxH" or "geom=WxHxD" to specify the width, height, and optionally the color depth. E.g. "fred:geom=800x600" at the login: prompt. Also if the env. var X11VNC_CREATE_GEOM is set to the desired WxH or WxHxD that will be used by x11vnc. You can set the env. var X11VNC_SKIP_DISPLAY to a comma separated list of displays to ignore in the FINDDISPLAY process (to force creation of new displays in some cases.) The user logging in via the vncviewer can also set this via username:nodisplay=...) If you do not plan on using the Java Web browser applet you can remove the -http (and -prog) option since this will speed up logging-in by a few seconds (x11vnc will not have to wait to see if a connection is HTTPS or VNC.) For reference, xinetd format in the file, say, /etc/xinetd.d/x11vnc: ``` service x11vnc { type = UNLISTED port = 5900 socket_type = stream protocol = tcp wait = no user = root server = /usr/local/bin/x11vnc server_args = -inetd -o /var/log/x11vnc.log -http -prog /usr/local/ bin/x11vnc -svc disable = no } ``` To print out the script in this case use "-display WAIT:cmd=FINDCREATEDISPLAY-print". To change the preference of Xservers and which to try list them, e.g.: "-display WAIT:cmd=FINDCREATEDISPLAY-X,Xvfb,Xdummy" or use "-create_xsrv X,Xvfb,Xdummy". The "X" one means to try to start up a real, hardware X server, e.g. startx(1) (if there is already a real X server running this may only work on Linux and the chvt program may need to be run to switch to the correct Linux virtual terminal.) x11vnc will try to run chvt automatically if it can determine which VT should be switched to. XDM/GDM/KDM Login Greeter Panel: If you want to present the user with a xdm/gdm/kdm display manager "greeter" login you can use Xvfb.xdmcp instead of Xvfb, etc in the above list. However, you need to configure xdm/gdm/kdm to accept localhost XDMCP messages, this can be done by (from -help output): ``` If you want the FINDCREATEDISPLAY session to contact an XDMCP login manager (xdm/gdm/kdm) on the same machine, then use "Xvfb.xdmcp" instead of "Xvfb", etc. The user will have to supply his username and password one more time (but he gets to select his desktop type so that can be useful.) For this to work, you will need to enable localhost XDMCP (udp port 177) for the display manager. This seems to be: for gdm in gdm.conf: Enable=true in section [xdmcp] for kdm in kdmrc: Enable=true in section [Xdmcp] for xdm in xdm-config: DisplayManager.requestPort: 177 ``` Unless you are also providing XDMCP service to xterminals or other machines, make sure that the host access list only allows local connections (the name of this file is often Xaccess and it is usually setup by default to do just that.) Nowadays, host level firewalling will also typically block UDP (port 177 for XDMCP) by default effectively limiting the UDP connections to localhost. Tip: Note that -xdmsvc is a short hand alias for the long "-ssl SAVE -unixpw -users unixpw= -display WAIT:cmd=FINDCREATEDISPLAY-Xvfb.xdmcp". So we simply use: ``` service x11vnc { type = UNLISTED port = 5900 socket_type = stream protocol = tcp wait = no user = root server = /usr/local/bin/x11vnc server_args = -inetd -o /var/log/x11vnc.log -xdmsvc disable = no } ``` (Note: use "-svc" instead of "-xdmsvc" for no XDMCP login greeter.) Local access (VNC Server and VNC Viewer on the same machine): To access your virtual X display session locally (i.e. while sitting at the same machine it is running on) one can perhaps have something like this in their $HOME/.xinitrc ``` #!/bin/sh x11vnc -create -rfbport 5905 -env WAITBG=1 vncviewer -geometry +0+0 -encodings raw -passwd $HOME/.vnc/passwd localhost:5 ``` You may not need the -passwd. Recent RealVNC viewers might be this: ``` #!/bin/sh x11vnc -create -rfbport 5905 -env WAITBG=1 vncviewer -FullScreen -PreferredEncoding raw -passwd $HOME/.vnc/passwd localhost:5 ``` This way a bare X server is run with no window manager or desktop; it simply runs only the VNC Viewer on the real X server. The Viewer then draws the virtual X session on to the real one. On your system it might not be $HOME/.xinitrc, but rather .xsession, .Xclients, or something else. You will need to figure out what it is for your system and configuration. There may be a problem if the resolution (WxH) of the virtual X display does not match that of the physical X display. If you do not want to or cannot figure out the X startup script name (.xinitrc, etc) you could save the above commands to a shell script, say "vnclocal", and the log in via the normal KDM or GDM greeter program using the "Failsafe" option. Then in the lone xterm that comes up type "vnclocal" to connect to your virtual X display via x11vnc and vncviewer. --- Summary: The "-display WAIT:cmd=FINDCREATEDISPLAY" scheme can be used to provide a "desktop service" (i.e. terminal service) on the server machine: you always get some desktop there, either a real hardware X server or a virtual one (depending on how you set things up.) So it provides simple "terminal services" based on Unix username and password. The created X server sessions (virtual or real hardware) will remain running after you disconnect the VNC viewer and will be found again on reconnecting via VNC and logging in. To terminate them use the normal way to Exit/LogOut from inside your X session. The user does not have to memorize which VNC display number is his. They all go the same one (e.g. hostname:0) and it switches based on username. ### Q-63: Can I have x11vnc restart itself after it terminates? One could do this in a shell script, but now there is an option -loop that makes it easier. Of course when x11vnc restarts it needs to have permissions to connect to the (potentially new) X display. This mode could be useful if the X server restarts often. Use e.g. "-loop5000" to sleep 5000 ms between restarts. Also "-loop2000,5" to sleep 2000 ms and only restart 5 times. One can also use the -loopbg to emulate inetd(8) to some degree, where each connected process runs in the background. It could be combined, say, with the -svc option to provide simple terminal services without using inetd(8). ### Q-64: How do I make x11vnc work with the Java VNC viewer applet in a web browser? To have x11vnc serve up a Java VNC viewer applet to any web browsers that connect to it, run x11vnc with this option: ``` -httpdir /path/to/the/java/classes/dir ``` (this directory will contain the files index.vnc and, for example, VncViewer.jar) Note that libvncserver contains the TightVNC Java classes jar file for your convenience. (it is the file classes/VncViewer.jar in the source tree.) You will see output something like this: ``` 14/05/2004 11:13:56 Autoprobing selected port 5900 14/05/2004 11:13:56 Listening for HTTP connections on TCP port 5800 14/05/2004 11:13:56 URL http://walnut:5800 14/05/2004 11:13:56 screen setup finished. 14/05/2004 11:13:56 The VNC desktop is walnut:0 PORT=5900 ``` then you can connect to that URL with any Java enabled browser. Feel free to customize the default index.vnc file in the classes directory. As of May/2005 the -http option will try to guess where the Java classes jar file is by looking in expected locations and ones relative to the x11vnc binary. Also note that if you wanted to, you could also start the Java viewer entirely from the viewer-side by having the jar file there and using either the java or appletviewer commands to run the program. ``` java -cp ./VncViewer.jar VncViewer HOST far-away.east PORT 5900 ``` Proxies: See the discussion here if the web browser must use a web proxy to connect to the internet. It is tricky to get Java applets to work in this case: a signed applet must be used so it can connect to the proxy and ask for the redirection to the VNC server. One way to do this is to use the signed SSL one referred to in classes/ssl/proxy.vnc and set disableSSL=yes (note that this has no encryption; please use SSL or SSH as discuss elsewhere on this page) in the URL or the file. ### Q-65: Are reverse connections (i.e. the VNC server connecting to the VNC viewer) using "vncviewer -listen" and vncconnect(1) supported? As of Mar/2004 x11vnc supports reverse connections. On Unix one starts the VNC viewer in listen mode: "vncviewer -listen" (see your documentation for Windows, etc), and then starts up x11vnc with the -connect option. To connect immediately at x11vnc startup time use the "-connect host:port" option (use commas for a list of hosts to connect to.) The ":port" is optional (default is VNC listening port is 5500.) If a file is specified instead: -connect /path/to/some/file then that file is checked periodically (about once a second) for new hosts to connect to. The -remote control option (aka -R) can also be used to do this during an active x11vnc session, e.g.: ``` x11vnc -display :0 -R connect:hostname.domain ``` Use the "-connect_or_exit" option to have x11vnc exit if the reverse connection fails. Also, note the "-rfbport 0" option disables TCP listening for connections (potentially useful for reverse connection mode, assuming you do not want any "forward" connections.) Note that as of Mar/2006 x11vnc requires password authentication for reverse connections as well as for forward ones (assuming password auth has been enabled, e.g. via -rfbauth, -passwdfile, etc.) Many VNC servers do not require any password for reverse connections. To regain the old behavior supply this option "-env X11VNC_REVERSE_CONNECTION_NO_AUTH=1" to x11vnc. Vncconnect command: To use the vncconnect(1) program (from the core VNC package at www.realvnc.com) specify the -vncconnect option to x11vnc (Note: as of Dec/2004 -vncconnect is now the default.) vncconnect(1) must be pointed to the same X11 DISPLAY as x11vnc (since it uses X properties to communicate with x11vnc.) If you do not have or do not want to get the vncconnect(1) program, the following script (named "Vncconnect") may work if your xprop(1) supports the -set option: ``` #!/bin/sh # usage: Vncconnect # Vncconnect # note: not all xprop(1) support -set. # xprop -root -f VNC_CONNECT 8s -set VNC_CONNECT "$1" ``` ### Q-66: Can reverse connections be made to go through a Web or SOCKS proxy or SSH? Yes, as of Oct/2007 x11vnc supports reverse connections through proxies: use the "-proxy host:port" option. The default is to assume the proxy is a Web proxy. Note that most Web proxies only allow proxy destination connections to ports 443 (HTTPS) and 563 (SNEWS) and so this might not be too useful unless the proxy has been modified (AllowCONNECT apache setting) or the VNC viewer listens on one of those ports (or the router does a port redir.) A web proxy may also be specified via "-proxy http://host:port" For SOCKS4 and SOCKS4a proxies use this format "-proxy socks://host:port". If the reverse connection hostname is a numerical IP or "localhost" then SOCKS4 (no host lookup) is used, otherwise SOCKS4a will be used. For SOCKS5 (proxy will do lookup and many other things) use "-proxy socks5://host:port". Note that the SSH builtin SOCKS proxy "ssh -D port" only does SOCKS4 or SOCKS5, so use socks5:// for a ssh -D proxy. The proxying works for both SSL encrypted and normal reverse connections. An experimental mode is "-proxy http://host:port/..." where the URL (e.g. a CGI script) is retrieved via the GET method. See -proxy for more info. Another experimental mode is "-proxy ssh://user@host" in which case a SSH tunnel is used for the proxying. See -proxy for more info. Up to 3 proxies may be chained together by listing them by commas e.g.: "-proxy http://host1:port1,socks5://host2:port2" in case one needs to ricochet off of several machines to ultimately reach the listening viewer. ### Q-67: Can x11vnc provide a multi-user desktop web login service as an Apache CGI or PHP script? Yes. See the example script desktop.cgi for ideas. It is in the source tree in the directory x11vnc/misc. It serves x11vnc's SSL enabled Java Applet to the web browser with the correct connection information for the user's virtual desktop (an Xvfb session via -create; be sure to add the Xvfb package.) HTTPS/SSL enabled Apache should be used to serve the script to avoid unix and vnc passwords from being sent in cleartext and sniffed. By default it uses a separate VNC port for each user desktop (either by autoprobing in a range of ports or using a port based on the userid number.) The web server's firewall must allow incoming connections to these ports. It is somewhat difficult to do all of this with x11vnc listening on a single port, however there is also a 'fixed port' scheme described in the script based on -loopbg that works fairly well (but more experience is needed to see what problems contention for the same port causes; however at worst one user may need to re-login.) There is also an optional 'port redirection' mode for desktop.cgi that allows redirection to other machines inside the firewall already running SSL enabled VNC servers. This provides much of the functionality as the SSL Portal and is easier to set up. ### Q-68: Can I use x11vnc as a replacement for Xvnc? (i.e. not for a real display, but for a virtual one I keep around.) You can, but you would not be doing this for performance reasons (for virtual X sessions via VNC, Xvnc should give the fastest response.) You may want to do this because Xvnc is buggy and crashes, does not support an X server extension you desire, or you want to take advantage of one of x11vnc's unending number of options and features. One way to achieve this is to have a Xvfb(1) virtual framebuffer X server running in the background and have x11vnc attached to it. Another method, faster and more accurate, is to use the "dummy" Device Driver in XFree86/Xorg (see below.) For these virtual sessions you will need to install the Xvfb program (e.g. apt-get install xvfb) or our Xdummy program (see below.) In either case, one can view this desktop both remotely and also locally using vncviewer. Make sure vncviewer's "-encodings raw" is in effect for local viewing (compression seems to slow things down locally.) For local viewing you set up a "bare" window manager that just starts up vncviewer and nothing else (See how below.) Here is one way to start up Xvfb: ``` xinit -- /usr/bin/Xvfb :1 -cc 4 -screen 0 1024x768x16 ``` This starts up a 16bpp virtual display. To export it via VNC use ``` x11vnc -display :1 ... ``` Then have the remote vncviewer attach to x11vnc's VNC display (e.g. :0 which is port 5900.) The "-cc 4" Xvfb option is to force it to use a TrueColor visual instead of DirectColor (this works around a recent bug in the Xorg Xvfb server.) One good thing about Xvfb is that the virtual framebuffer exists in main memory (rather than in the video hardware), and so x11vnc can "screen scrape" it very efficiently (more than, say, 100X faster than normal video hardware.) Update Nov/2006: See the FINDCREATEDISPLAY discussion of the "-display WAIT:cmd=FINDDISPLAY" option where virtual (Xvfb or Xdummy, or even real ones by changing an option) X servers are started automatically for new users connecting. This provides a "desktop service" for the machine. You either get your real X session or your virtual (Xvfb/Xdummy) one whenever you connect to the machine (inetd(8) is a nice way to provide this service.) The -find, -create, -svc, and -xdmsvc aliases can also come in handy here. There are some annoyances WRT Xvfb however. The default keyboard mapping seems to be very poor. One should run x11vnc with -add_keysyms option to have keysyms added automatically. Also, to add the Shift_R and Control_R modifiers something like this is needed: ``` #!/bin/sh xmodmap -e "keycode any = Shift_R" xmodmap -e "add Shift = Shift_L Shift_R" xmodmap -e "keycode any = Control_R" xmodmap -e "add Control = Control_L Control_R" xmodmap -e "keycode any = Alt_L" xmodmap -e "keycode any = Alt_R" xmodmap -e "keycode any = Meta_L" xmodmap -e "add Mod1 = Alt_L Alt_R Meta_L" ``` (note: these are applied automatically in the FINDCREATEDISPLAY mode of x11vnc.) Perhaps the Xvfb options -xkbdb or -xkbmap could be used to get a better default keyboard mapping... Dummy Driver: A user points out a faster and more accurate method is to use the "dummy" Device Driver of XFree86/Xorg instead of Xvfb. He uses this to create a persistent and resizable desktop accessible from anywhere. In the Device Section of the config file set Driver "dummy". You may also need to set VideoRam NNN to be large enough to hold the framebuffer. The framebuffer is kept in main memory like Xvfb except that the server code is closely correlated with the real XFree86/Xorg Xserver unlike Xvfb. The main drawback to this method (besides requiring extra configuration and possibly root permission) is that it also does the Linux Virtual Console/Terminal (VC/VT) switching even though it does not need to (since it doesn't use a real framebuffer.) There are some "dual headed" (actually multi-headed/multi-user) patches to the X server that turn off the VT usage in the X server. Update: As of Jul/2005 we have an LD_PRELOAD script Xdummy that allows you to use a stock (i.e. unpatched) Xorg or XFree86 server with the "dummy" driver and not have any VT switching problems! An advantage of Xdummy over Xvfb is that Xdummy supports RANDR dynamic screen resizing. The standard way to start the "dummy" driver would be: ``` startx -- :1 -config /etc/X11/xorg.conf.dummy ``` where the file /etc/X11/xorg.conf.dummy has its Device Section modified as described above. To use the LD_PRELOAD wrapper script: ``` startx -- /path/to/Xdummy :1 ``` An xdm(1) example is also provided. In general, one can use these sorts of schemes to use x11vnc to export other virtual X sessions, say Xnest or even Xvnc itself (useful for testing x11vnc.) Local access (VNC Server and VNC Viewer on the same machine): You use a VNC viewer to access the display remotely; to access your virtual X display locally (i.e. while sitting at the same machine it is running on) one can perhaps have something like this in their $HOME/.xinitrc ``` #!/bin/sh x11vnc -display :5 -rfbport 5905 -bg vncviewer -geometry +0+0 -encodings raw -passwd $HOME/.vnc/passwd localhost:5 ``` The display numbers (VNC and X) will likely be different (you could also try -find), and you may not need the -passwd. Recent RealVNC viewers might be this: ``` #!/bin/sh x11vnc -display :5 -rfbport 5905 -bg vncviewer -FullScreen -PreferredEncoding raw -passwd $HOME/.vnc/passwd localhost:5 ``` This way a bare X server is run with no window manager or desktop; it simply runs only the VNC Viewer on the real X server. The Viewer then draws the virtual X session on to the real one. On your system it might not be $HOME/.xinitrc, but rather .xsession, .Xclients, or something else. You will need to figure out what it is for your system and configuration. XDM/GDM/KDM One-Shot X sessions: For the general replacement of Xvnc by Xvfb+x11vnc, one user describes a similar setup he created where the X sessions are one-shot's (destroyed after the vncviewer disconnects) and it uses the XDM/GDM/KDM login greeter here. ### Q-69: How can I use x11vnc on "headless" machines? Why might I want to? An interesting application of x11vnc is to let it export displays of "headless" machines. For example, you may have some lab or server machines with no keyboard, mouse, or monitor, but each one still has a video card. One can use x11vnc to provide a simple "desktop service" from these server machines. An X server can be started on the headless machine (sometimes this requires configuring the X server to not fail if it cannot detect a keyboard or mouse, see the next paragraph.) Then you can export that X display via x11vnc (e.g. see this FAQ) and access it from anywhere on the network via a VNC viewer. Some tips on getting X servers to start on machines without keyboard or mouse: For XFree86/Xorg the Option "AllowMouseOpenFail" "true" "ServerFlags" config file option is useful. On Solaris Xsun the +nkeyboard and +nmouse options are useful (put them in the server command line args in /etc/dt/config/Xservers.) There are patches available for Xsun at lease back to Solaris 8 that support this. See Xserver(1) for more info. Although this usage may sound strange it can be quite useful for a GUI (or other) testing or QA setups: the engineers do not need to walk to lab machines running different hardware, OS's, versions, etc (or have many different machines in their office.) They just connect to the various test machines over the network via VNC. The advantage to testing this way instead of using Xvnc or even Xvfb is that the test is done using the real X server, fonts, video hardware, etc. that will be used in the field. One can imagine a single server machine crammed with as many video cards as it can hold to provide multiple simultaneous access or testing on different kinds of video hardware. See also the FINDCREATEDISPLAY discussion of the "-display WAIT:cmd=FINDDISPLAY" option where virtual Xvfb or Xdummy, or real X servers are started automatically for new users connecting. The -find, -create, -svc, and -xdmsvc aliases can also come in handy here. ## Resource Usage and Performance ### Q-70: I have lots of memory, but why does x11vnc fail with shmget: No space left on device or Minor opcode of failed request: 1 (X_ShmAttach)? It is not a matter of free memory, but rather free shared memory (shm) slots, also known as shm segments. This often occurs on a public Solaris machine using the default of only 100 slots. You (or the owner or root) can clean them out with ipcrm(1). x11vnc tries hard to release its slots, but it, and other programs, are not always able to (e.g. if kill -9'd.) Sometimes x11vnc will notice the problem with shm segments and tries to get by with fewer, only giving a warning like this: ``` 19/03/2004 10:10:58 shmat(tile_row) failed. shmat: Too many open files 19/03/2004 10:10:58 error creating tile-row shm for len=4 19/03/2004 10:10:58 reverting to single_copytile mode ``` Here is a shell script shm_clear to list and prompt for removal of your unattached shm segments (attached ones are skipped.) I use it while debugging x11vnc (I use "shm_clear -y" to assume "yes" for each prompt.) If x11vnc is regularly not cleaning up its shm segments, please contact me so we can work to improve the situation. Longer term, on Solaris you can put something like this in /etc/system: ``` set shmsys:shminfo_shmmax = 0x2000000 set shmsys:shminfo_shmmni = 0x1000 ``` to sweep the problem under the rug (4096 slots.) On Linux, examine /proc/sys/kernel/shmmni; you can modify the value by writing to that file. Things are even more tight on Solaris 8 and earlier, there is a default maximum number of shm segments per process of 6. The error is the X server (not x11vnc) being unable to attach to the segments, and looks something like this: ``` 30/04/2004 14:04:26 Got connection from client 192.168.1.23 30/04/2004 14:04:26 other clients: X Error of failed request: BadAccess (attempt to access private resource denied) Major opcode of failed request: 131 (MIT-SHM) Minor opcode of failed request: 1 (X_ShmAttach) Serial number of failed request: 14 Current serial number in output stream: 17 ``` This tight limit on Solaris 8 can be increased via: ``` set shmsys:shminfo_shmseg = 100 ``` in /etc/system. See the next paragraph for more workarounds. To minimize the number of shm segments used by x11vnc try using the -onetile option (corresponds to only 3 shm segments used, and adding -fs 1.0 knocks it down to 2.) If you are having much trouble with shm segments, consider disabling shm completely via the -noshm option. Performance will be somewhat degraded but when done over local machine sockets it should be acceptable (see an earlier question discussing -noshm.) ### Q-71: How can I make x11vnc use less system resources? The -nap (now on by default; use -nonap to disable) and "-wait n" (where n is the sleep between polls in milliseconds, the default is 30 or so) option are good places to start. In addition, something like "-sb 15" will cause x11vnc to go into a deep-sleep mode after 15 seconds of no activity (instead of the default 60.) Reducing the X server bits per pixel depth (e.g. to 16bpp or even 8bpp) will further decrease memory I/O and network I/O. The ShadowFB X server setting will make x11vnc's screen polling less severe. Using the -onetile option will use less memory and use fewer shared memory slots (add -fs 1.0 for one less slot.) ### Q-72: How can I make x11vnc use MORE system resources? You can try -threads (note this mode can be unstable and/or crash; and as of May/2008 is strongly discouraged, see the option description) or dial down the wait time (e.g. -wait 1) and possibly dial down -defer as well. Note that if you try to increase the "frame rate" too much you can bog down the server end with the extra work it needs to do compressing the framebuffer data, etc. That said, it is possible to "stream" video via x11vnc if the video window is small enough. E.g. a 256x192 xawtv TV capture window (using the x11vnc -id option) can be streamed over a LAN or wireless at a reasonable frame rate. If the graphics card's framebuffer read rate is faster than normal then the video window size and frame rate can be much higher. The use of TurboVNC and/or TurboJPEG can make the frame rate somewhat higher still (but most of this hinges on the graphics card's read rate.) ### Q-73: I use x11vnc over a slow link with high latency (e.g. dialup modem or broadband), is there anything I can do to speed things up? Some things you might want to experiment with (many of which will help performance on faster links as well): X server/session parameters: * Configure the X server bits per pixel to be 16bpp or even 8bpp. (reduces amount of data needed to be polled, compressed, and sent) * Use a smaller desktop size (e.g. 1024x768 instead of 1280x1024) * Make sure the desktop background is a solid color (the background is resent every time it is re-exposed.) Consider using the -solid [color] option to try to do this automatically. * Configure your window manager or desktop "theme" to not use fancy images, shading, and gradients for the window decorations, etc. Disable window animations, etc. Maybe your desktop has a "low bandwidth" theme you can easily switch into and out of. Also in Firefox disable eye-candy, e.g.: Edit -> Preferences -> Advanced -> Use Smooth Scrolling (deselect it.) * Avoid small scrolls of large windows using the Arrow keys or scrollbar. Try to use PageUp/PageDown instead. (not so much of a problem in x11vnc 0.7.2 if -scrollcopyrect is active and detecting scrolls for the application.) * If the -wireframe option is not available (earlier than x11vnc 0.7.2 or you have disabled it via -nowireframe) then Disable Opaque Moves and Resizes in the window manager/desktop. * However if -wireframe is active (on by default in x11vnc 0.7.2) then you should Enable Opaque Moves and Resizes in the window manager! This seems counter-intuitive, but because x11vnc detects the move/resize events early there is a huge speedup over a slow link when Opaque Moves and Resizes are enabled. (e.g. CopyRect encoding will be used.) * Turn off Anti-aliased fonts on your system, web browser, terminal windows, etc. AA fonts do not compress as well as traditional fonts (sometimes 10X less.) * On Firefox/Mozilla (and anything else) turn off "Smooth Scroll" animations. In Firefox put in the URL "about:config" and set general.smoothScroll to false. * On Xorg/XFree86 turn on the Shadow Framebuffer to speed up reading. (Option "ShadowFB" "true" in the Device section of /etc/X11/XF86Config) This disables 2D acceleration on the physical display and so may not be worth it (if you play games, etc), but could be of use in some situations. Note: If the network link is very slow, this speedup may not be noticed. VNC viewer parameters: * Use a TightVNC enabled viewer! (Actually, RealVNC 4.x viewer with ZRLE encoding is not too bad either; some claim it is faster.) * Make sure the tight (or zrle) encoding is being used (look at vncviewer and x11vnc outputs) * Request 8 bits per pixel using -bgr233 (up to 4X speedup over depth 24 TrueColor (32bpp), but colors will be off) * RealVNC 4.x viewer has some extremely low color modes (only 64 and even 8 colors.) SSVNC does too. The colors are poor, but it is usually noticeably faster than bgr233 (256 colors.) * Try increasing the TightVNC -compresslevel (compresses more on server side before sending, but uses more CPU) * Try reducing the TightVNC -quality (increases JPEG compression, but is lossy with painting artifacts) * Try other VNC encodings via -encodings (tight may be the fastest, but you should compare it to zrle and maybe some of the others) * On the machine where vncviewer is run, make sure Backing Store is enabled (Xorg/XFree86 disables it by default causing re-exposures of vncviewer to be very slow) Option "backingstore" in config file. x11vnc parameters: * Make sure the -wireframe option is active (it should be on by default) and you have Opaque Moves/Resizes Enabled in the window manager. * Make sure the -scrollcopyrect option is active (it should be on by default.) This detects scrolls in many (but not all) applications an applies the CopyRect encoding for a big speedup. * Enforce a solid background when VNC viewers are connected via -solid * Try x11vnc's client-side caching client-side caching scheme: -ncache * Specify -speeds modem to force the wireframe and scrollcopyrect heuristic parameters (and any future ones) to those of a dialup modem connection (or supply the rd,bw,lat numerical values that characterize your link.) * If wireframe and scrollcopyrect aren't working, try using the more drastic -nodragging (no screen updates when dragging mouse, but sometimes you miss visual feedback) * Set -fs 1.0 (disables fullscreen updates) * Try increasing -wait or -defer (reduces the maximum "frame rate", but won't help much for large screen changes) * Try the -progressive pixelheight mode with the block pixelheight 100 or so (delays sending vertical blocks since they may change while viewer is receiving earlier ones) * If you just want to watch one (simple) window use -id or -appshare (cuts down extraneous polling and updates, but can be buggy or insufficient) * Set -nosel (disables all clipboard selection exchange) * Use -nocursor and -nocursorpos (repainting the remote cursor position and shape takes resources and round trips) * On very slow links (e.g. <= 28.8) you may need to increase the -readtimeout n setting if it sometimes takes more than 20sec to paint the full screen, etc. * Do not use -fixscreen to automatically refresh the whole screen, tap three Alt_L's then the screen has painting errors (rare problem.) Example for the KDE desktop: Launch the "KDE Control Center" utility. Sometimes this is called "Personal Settings". Select "Desktop". Then Select "Window Behavior". In the "Moving" Tab set these: * YES - Display content in moving windows * YES - Display content in resizing windows * NO - Display window geometry when moving or resizing * NO - Animate minimize and restore In the "Translucency" Tab set: * NO - Use translucency/shadows Next hit "Back" and then select "Panels". In the "Appearance" Tab set: * NO - Enable icon mouseover effects * NO - Enable transparency Now go all the way back up to the top and Select "Appearance & Themes". Select "Background" and set: * YES - No picture * Colors: Single Color Select "Fonts" and disable anti-aliased fonts if you are bold enough. Select "Launch Feedback" and set: * Busy Cursor: No Busy Cursor * NO - Enable taskbar notification Select "Screen Saver" and set: * Screen Saver: Blank Screen Select "Style" and in the "Effects" Tab set: * NO - Enable GUI effects Example for the GNOME desktop: * TBD. ### Q-74: Does x11vnc support the X DAMAGE Xserver extension to find modified regions of the screen quickly and efficiently? Yes, as of Mar/2005 x11vnc will use the X DAMAGE extension by default if it is available on the display. This requires libXdamage to be available in the build environment as well (recent Linux distros and Solaris 10 have it.) The DAMAGE extension enables the X server to report changed regions of the screen back to x11vnc. So x11vnc doesn't have to guess where the changes are (by polling every pixel of the entire screen every 2-4 seconds.) The use of X DAMAGE dramatically reduces the load when the screen is not changing very much (i.e. most of the time.) It also noticeably improves updates, especially for very small changed areas (e.g. clock ticking, cursor flashing, typing, etc.) Note that the DAMAGE extension does not speed up the actual reading of pixels from the video card framebuffer memory, by, say, mirroring them in main memory. So reading the fb is still painfully slow (e.g. 5MB/sec), and so even using X DAMAGE when large changes occur on the screen the bulk of the time is still spent retrieving them. Not ideal, but use of the ShadowFB XFree86/Xorg option speeds up the reading considerably (at the cost of h/w acceleration.) Unfortunately the current Xorg DAMAGE extension implementation can at times be overly conservative and report very large rectangles as "damaged" even though only a small portion of the pixels have actually been modified. This behavior is often the fault of the window manager (e.g. it redraws the entire, unseen, frame window underneath the application window when it gains focus), or the application itself (e.g. does large, unnecessary repaints.) To work around this deficiency, x11vnc currently only trusts small DAMAGE rectangles to contain real damage. The larger rectangles are only used as hints to focus the traditional scanline polling (i.e. if a scanline doesn't intersect a recent DAMAGE rectangle, the scan is skipped.) You can use the "-xd_area A" option to adjust the size of the trusted DAMAGE rectangles. The default is 20000 pixels (e.g. a 140x140 square, etc.) Use "-xd_area 0" to disable the cutoff and trust all DAMAGE rectangles. The option "-xd_mem f" may also be of use in tuning the algorithm. To disable using DAMAGE entirely use "-noxdamage". ### Q-75: My OpenGL application shows no screen updates unless I supply the -noxdamage option to x11vnc. One user reports in his environment (MythTV using the NVIDIA OpenGL drivers) he gets no updates after the initial screen is drawn unless he uses the "-noxdamage" option. This seems to be a bug in the X DAMAGE implementation of that driver. You may have to use -noxdamage as well. A way to autodetect this will be tried, probably the best it will do is automatically stop using X DAMAGE. A developer for MiniMyth reports that the 'alphapulse' tag of the theme G.A.N.T. can also cause problems, and should be avoided when using VNC. Update: see this FAQ too. ### Q-76: When I drag windows around with the mouse or scroll up and down things really bog down (unless I do the drag in a single, quick motion.) Is there anything to do to improve things? This problem is primarily due to slow hardware read rates from video cards: as you scroll or move a large window around the screen changes are much too rapid for x11vnc to keep up them (it can usually only read the video card at about 5-10 MB/sec, so it can take a good fraction of a second to read the changes induce from moving a large window, if this to be done a number of times in succession the window or scroll appears to "lurch" forward.) See the description in the -pointer_mode option for more info. The next bottleneck is compressing all of these changes and sending them out to connected viewers, however the VNC protocol is pretty much self-adapting with respect to that (updates are only packaged and sent when viewers ask for them.) As of Jan/2004 there are some improvements to libvncserver. The default should now be much better than before and dragging small windows around should no longer be a huge pain. If for some reason these changes make matters worse, you can go back to the old way via the "-pointer_mode 1" option. Also added was the -nodragging option that disables all screen updates while dragging with the mouse (i.e. mouse motion with a button held down.) This gives the snappiest response, but might be undesired in some circumstances when you want to see the visual feedback while dragging (e.g. menu traversal or text selection.) As of Dec/2004 the -pointer_mode n option was introduced. n=1 is the original mode, n=2 an improvement, etc.. See the -pointer_mode n help for more info. Also, in some circumstances the -threads option can improve response considerably. Be forewarned that if more than one vncviewer is connected at the same time then libvncserver may not be thread safe (try to get the viewers to use different VNC encodings, e.g. tight and ZRLE.) This option can be unstable and so as of Feb/2008 it is disabled by default. Set env. X11VNC_THREADED=1 to re-enable. As of Apr/2005 two new options (see the wireframe FAQ and scrollcopyrect FAQ below) provide schemes to sweep this problem under the rug for window moves or resizes and for some (but not all) window scrolls. These are the preferred way of avoiding the "lurching" problem, contact me if they are not working. Note on SuSE and some other distros the RECORD X extension used by scrollcopyrect is not enabled by default, turn it on in xorg.conf: ``` Section "Module" ... Load "record" ... EndSection ``` ### Q-77: Why not do something like wireframe animations to avoid the windows "lurching" when being moved or resized? Nice idea for a hack! As of Apr/2005 x11vnc by default will apply heuristics to try to guess if a window is being (opaquely) moved or resized. If such a change is detected framebuffer polling and updates will be suspended and only an animated "wireframe" (a rectangle outline drawn where the moved/resized window would be) is shown. When the window move/resize stops, it returns to normal processing: you should only see the window appear in the new position. This spares you from interacting with a "lurching" window between all of the intermediate steps. BTW the lurching is due to slow video card read rates (see here too.) A displacement, even a small one, of a large window requires a non-negligible amount of time, a good fraction of a second, to read in from the hardware framebuffer. Note that Opaque Moves/Resizes must be Enabled by your window manager for -wireframe to do any good. The mode is currently on by default because most people are afflicted with the problem. It can be disabled with the -nowireframe option (aka -nowf.) Why might one want to turn off the wireframing? Since x11vnc is merely guessing when windows are being moved/resized, it may guess poorly for your window-manager or desktop, or even for the way you move the pointer. If your window-manager or desktop already does its own wireframing then this mode is a waste of time and could do the wrong thing occasionally. There may be other reasons the new mode feels unnatural. If you have very expensive video hardware (SGI, well now even proprietary Xorg drivers are fast at reading) or are using an in-RAM video framebuffer (SunRay, ShadowFB, Xvfb), the read rate from that framebuffer may be very fast (100's of MB/sec) and so you don't really see much lurching (at least over a fast LAN): opaque moves look smooth in x11vnc. Note: ShadowFB is often turned on when you are using the vesafb or fbdev XFree86 video driver instead of a native one so you might be using it already and not know. The heuristics used to guess window motion or resizing are simple, but are not fool proof: x11vnc is sometimes tricked and so you'll occasionally see the lurching opaque move and rarely something even worse. First it assumes that the move/resize will occur with a mouse button pressed, held down and dragged (of course this is only mostly true.) Next it will only consider a window for wireframing if the mouse pointer is initially "close enough" to the edges of the window frame, e.g. you have grabbed the title bar or a resizer edge (this requirement can be disabled and it also not applied if a modifier key, e.g. Alt, is pressed.) If these are true, it will wait an amount of time to see if the window starts moving or resizing. If it does, it starts drawing the wireframe "outline" of where the window would be. When the mouse button is released, or a timeout occurs, it goes back to the standard mode to allow the actual framebuffer changes to propagate to the viewers. These parameters can be tweaked: * Color/Shade of the wireframe. * Linewidth of the outline frame. * Cutoff size of windows to not apply wireframing to. * Cutoffs for closeness to Top, Bottom, Left, and Right edges of window. * Modifier keys to enable interior window grabbing. * Maximum time to wait for dragging pointer events. * Maximum time to wait for the window to start moving/resizing. * Maximum time to show a wireframe animation. * Minimum time between sending wireframe outlines. See the "-wireframe tweaks" option for more details. On a slow link, e.g. dialup modem, the parameters may be automatically adjusted for better response. CopyRect encoding: In addition to the above there is the "-wirecopyrect mode" option. It is also on by default. This instructs x11vnc to not only show the wireframe animation, but to also instruct all connected VNC viewers to locally translate the window image data from the original position to the new position on the screen when the animation is done. This speedup is the VNC CopyRect encoding: the framebuffer update doesn't need to send the actual new image data. This is nice in general, and very convenient over a slow link, but since it is based on heuristics you may need to disable it with the -nowirecopyrect option (aka -nowcr) if it works incorrectly or unnaturally for you. The -wirecopyrect modes are: "never" (same as -nowirecopyrect); "top", only apply the CopyRect if the window is appears to be on the top of the window stack and is not obstructed by other windows; and "always" to always try to apply the CopyRect (obstructed regions are usually clipped off and not translated.) Note that some desktops (KDE and xfce) appear to mess with the window stacking in ways that are not yet clear. In these cases x11vnc works around the problem by applying the CopyRect even if obscuring windows' data is translated! Use -nowirecopyrect if this yields undesirable effects for your desktop. Also, the CopyRect encoding may give incorrect results under -scale (depending on the scale factor the CopyRect operation is often only approximate: the correctly scaled framebuffer will be slightly different from the translated one.) x11vnc will try to push a "cleanup" update after the CopyRect if -scale is in effect. Use -nowirecopyrect if this or other painting errors are unacceptable. ### Q-78: Can x11vnc try to apply heuristics to detect when a window is scrolling its contents and use the CopyRect encoding for a speedup? Another nice idea for a hack! As of May/2005 x11vnc will by default apply heuristics to try to detect if the window that has the input focus is scrolling its contents (but only when x11vnc is feeding user input, keystroke or pointer, to the X server.) So, when detected, scrolls induced by dragging on a scrollbar or by typing (e.g. Up or Down arrows, hitting Return in a terminal window, etc), will show up much more quickly than via the standard x11vnc screen polling update mechanism. There will be a speedup for both slow and fast links to viewers. For slow links the speedup is mostly due to the CopyRect encoding not requiring the image data to be transmitted over the network. For fast links the speedup is primarily due to x11vnc not having to read the scrolled framebuffer data from the X server (recall that reading from the hardware framebuffer is slow.) To do this x11vnc uses the RECORD X extension to snoop the X11 protocol between the X client with the focus window and the X server. This extension is usually present on most X servers (but SuSE disables it for some reason.) On XFree86/Xorg it can be enabled via Load "record" in the Module section of the config file if it isn't already: ``` Section "Module" ... Load "record" ... EndSection ``` Currently the RECORD extension is used as little as possible so as to not slow down regular use. Only simple heuristics are applied to detect XCopyArea and XConfigureWindow calls from the application. These catch a lot of scrolls, e.g. in mozilla/firefox and in terminal windows like gnome-terminal and xterm. Unfortunately the toolkits KDE applications use make scroll detection less effective (only rarely are they detected: i.e. Konqueror and Konsole don't work.) An interesting project, that may be the direction x11vnc takes, is to record all of the X11 protocol from all clients and try to "tee" the stream into a modified Xvfb watching for CopyRect and other VNC speedups. A potential issue is the RECORD stream is delayed from actual view on the X server display: if one falls too far behind it could become a mess... The initial implementation of -scrollcopyrect option is useful in that it detects many scrolls and thus gives a much nicer working environment (especially when combined with the -wireframe -wirecopyrect options, which are also on by default; and if you are willing to enable the ShadowFB things are very fast.) The fact that there aren't long delays or lurches during scrolling is the primary improvement. But there are some drawbacks: * Not all scrolls are detected. Some apps scroll windows in ways that cannot currently be detected, and other times x11vnc "misses" the scroll due to timeouts, etc. Sometimes it is more distracting that a speedup occasionally doesn't work as opposed to being consistently slow! * For rapid scrolling (i.e. sequence of many scrolls over a short period) there can be painting errors (tearing, bunching up, etc.) during the scroll. These will repair themselves after the scroll is over, but when they are severe it can be distracting. Try to think of the approximate window contents as a quicker and more useful "animation" compared to the slower polling scheme... * Scrolling inside shells in terminal windows (gnome-terminal, xterm), can lead to odd painting errors. This is because x11vnc did not have time to detect a screen change just before the scroll (most common is the terminal undraws the block cursor before scrolling the text up: in the viewer you temporarily see multiple block cursors.) Another issue is with things like more(1): scroll detection for 5-6 lines happens nicely, but then it can't keep up and so there is a long pause for the standard polling method to deliver the remaining updates. * More rarely sometimes painting errors are not repaired after the scroll is over. This may be a bug in x11vnc or libvncserver, or it may be an inescapable fact of the CopyRect encoding and the delay between RECORD callbacks and what is actually on the X display. One can tap the Alt_L key (Left "Alt" key) 3 times in a row to signal x11vnc to refresh the screen to all viewers. Your VNC-viewer may have its own screen refresh hot-key or button. See also: -fixscreen * Some applications, notably OpenOffice, do XCopyArea scrolls in weird ways that assume ancestor window clipping is taking place. See the -scr_skip option for ways to tweak this on a per-application basis. * Selecting text while dragging the mouse may be slower, especially if the Button-down event happens near the window's edge. This is because the scrollcopyrect scheme is watching for scrolls via RECORD and has to wait for a timeout to occur before it does the update. * For reasons not yet understood the RECORD extension can stop responding (and hence scrolls are missed.) As a workaround x11vnc attempts to reset the RECORD connection every 60 seconds or so. Another workaround is to type 4 Super_L (Left Super/Windows-Flag key) in a row to reset RECORD. Work is in progress to try to fix this bug. * Sometimes you need to "retrain" x11vnc for a certain window because it fails to detect scrolls in it. Sometimes clicking inside the application window or selecting some text in it to force the focus helps. * When using the -scale option there will be a quick CopyRect scroll, but it needs to be followed by a slower "cleanup" update. This is because for a fixed finite screen resolution (e.g. 75 dpi) scaling and copyrect-ing are not exactly independent. Scaling involves a blending of nearby pixels and if you translate a pixel the neighbor pixel weighting may be different. So you have to wait a bit for the cleanup update to finish. On slow links x11vnc may automatically decide to not detect scrolls when -scale is in effect. In general it will also try to defer the cleanup update if possible. If you find the -scrollcopyrect behavior too approximate or distracting you can go back to the standard polling-only update method with the -noscrollcopyrect (or -noscr for short.) If you find some extremely bad and repeatable behavior for -scrollcopyrect please report a bug. Alternatively, as with -wireframe, there are many tuning parameters to try to improve the situation. You can also access these parameters inside the gui under "Tuning". These parameters can be tweaked: * The minimum pixel area of a rectangle to be watched for scrolls. * A list if application names to skip scroll detection. * Which keystrokes should trigger scroll detection. * Which applications should have a "terminal" tweak applied to them. * When repeating keys (e.g. Up arrow) should be discarded to preserve a scroll. * Cutoffs for closeness to Top, Bottom, Left, and Right edges of window for mouse induced scrolls. * Set timeout parameters for keystroke induced scrolls. * Set timeout parameters for mouse pointer induced scrolls. * Have the full screen be periodically refreshed to fix painting errors. ### Q-79: Can x11vnc do client-side caching of pixel data? I.e. so when that pixel data is needed again it does not have to be retransmitted over the network. As of Dec/2006 in the 0.9 development tarball there is an experimental client-side caching implementation enabled by the "-ncache n" option. In fact, during the test period it was on by default with n set to 10. To disable it use "-noncache". It is a simple scheme where a (very large) lower portion of the framebuffer (i.e. starting just below the user's actual desktop display) is used for storing pixel data. CopyRect; a fast, essentially local viewer-side VNC encoding; is used to swap the pixel data in and out of the actual display area. It gives an excellent speedup for iconifying/deiconifying and moving windows and re-posting of menus (often it doesn't feel like VNC at all: there is no delay waiting for the pixel data to fill in.) This scheme is nice because it does all of this within the existing VNC protocol, and so it works with all VNC viewers. A challenge to doing more sophisticated (e.g. compressed and/or shared) client-side caching is that one needs to extend the VNC protocol, modify a viewer and then also convince users to adopt your modified VNC Viewer (or get the new features to be folded into the main VNC viewers, patches accepted, etc... likely takes many years before they might be deployed in the field.) So it is convenient that the "-ncache n" works with any unaltered VNC viewer. A drawback of the "-ncache n" method is that in the VNC Viewer you can scroll down and actually see the cached pixel data. So it looks like there is a bug: you can scroll down in your viewer and see a strange "history" of windows on your desktop. This is working as intended. One will need to try to adjust the size of his VNC Viewer window so the cache area cannot be seen. SSVNC (see below) can do this automatically. At some point LibVNCServer may implement a "rfbFBCrop" pseudoencoding that viewers can use to learn which portion of the framebuffer to actually show to the users (with the hidden part used for caching, or perhaps something else, maybe double buffering or other offscreen rendering...) The Enhanced TightVNC Viewer (SSVNC) Unix viewer has a nice -ycrop option to help hide the pixel cache area from view. It will turn on automatically if the framebuffer appears to be very tall (height more than twice the width), or you can supply the actual value for the height. If the screen is resized by scaling, etc, the ycrop value is scaled as well. In fullscreen mode you cannot scroll past the end of the actual screen, and in non-fullscreen mode the window manager frame is adjusted to fit the actual display (so you don't see the pixel cache region) and the scrollbars are very thin to avoid distraction and trouble fitting inside your display. Use the "-sbwidth n" viewer option to make the scrollbars thicker if you like. Another drawback of the scheme is that it is VERY memory intensive, the n in "-ncache n" is the factor of increase over the base framebuffer size to use for caching. It is an even integer and should be fairly large, 6-12, to achieve good response. This usually requires about 50-100MB of additional RAM on both the client and server sides. For example with n=6 a 1280x1024 display will use a framebuffer that is 1280x7168: everything below row 1024 is the pixel buffer cache. If you are running on low memory machines or memory is tight because of other running applications you should not use -ncache. The reason for so much memory is because the pixel data is not compressed and so the whole window to be saved must be stored "offscreen". E.g. for a large web browser window this can be nearly 1 million pixels, and that is only for a single window! One typically wants to cycle between 5-10 large active windows. Also because both backing-store (the window's actual contents) and save-unders (the pixels covered up by the window) are cached offscreen that introduces an additional factor of 2 in memory use. However, even in the smallest usage mode with n equal 2 and -ncache_no_rootpixmap set (this requires only 2X additional framebuffer memory) there is still a noticable improvement for many activities, although it is not as dramatic as with, say n equal 12 and rootpixmap (desktop background) caching enabled. The large memory consumption of the current implementation can be thought of as a tradeoff to providing caching and being compatible with all VNC viewers and also ease of implementing. Hopefully it can be tuned to use less, or the VNC community will extend the protocol to allow caching and replaying of compressed blobs of data. Another option to experiment with is "-ncache_cr". By specifying it, x11vnc will try to do smooth opaque window moves instead of its wireframe. This can give a very nice effect (note: on Unix the realvnc viewer seems to be smoother than the tightvnc viewer), but can lead to some painting problems, and can be jerky in some circumstances. Surprisingly, for very slow connections, e.g. modem, the -ncache_cr option can actually improve window drags. This is probably because no pixel data (only CopyRect instructions) are sent when dragging a window. Normally, the wireframe must be sent and this involves compressing and sending the lines that give rise to the moving box effect (note that real framebuffer data is sent to "erase" the white lines of the box.) If you experience painting errors you can can tap the Alt_L key (Left "Alt" key) 3 times in a row to signal x11vnc to refresh the screen to all viewers. You may also need to iconify and then deiconify any damaged windows to correct their cache data as well. Note that if you change color viewer depth (e.g. 8bpp to full color) dynamically that will usually lead to the entire extended framebuffer being resent which can take a long time over very slow links: it may be better to reconnect and reset the format right after doing so. x11vnc will try to detect the format change and clear (make completely black) the cache region. Gotcha for older Unix VNC Viewers: The older Unix VNC viewers (e.g. current TightVNC Unix Viewer) require X server backingstore to keep off-viewer screen data local. If the viewer-side X server has backingstore disabled (sadly, currently the default on Linux, etc), then to get the offscreen pixels the viewer has to ask for a refresh over the network, thereby defeating the caching. Use something like this in your viewer-side /etc/X11/xorg.conf file (or otherwise get your viewer-side system to do it) ``` Section "Device" ... Option "backingstore" ... EndSection ``` No problems like this have been observed with Windows VNC Viewers: they all seem to keep their entire framebuffer in local memory. Gotcha for KDE krdc VNC Viewer: One user found that KDE's krdc viewer has some sort of hardwired limit on the maximum size of the framebuffer (64MB?). It fails quickly saying "The connection to the host has been interrupted." The workaround for his 1280x1024 x11vnc-side display was to run with "-ncache 10", i.e. a smaller value to be under the krdc threshold. Although this scheme is not as quick (nor as compressed) as nx/nomachine, say, it does provide a good step in the direction of improving VNC performance by client side caching. ### Q-80: Does x11vnc support TurboVNC? As of Feb/2009 (development tarball) there is an experimental kludge to let you build x11vnc using TurboVNC's modified TightVNC encoding. TurboVNC is part of the VirtualGL project. It does two main things to speed up the TightVNC encoding: * It eliminates bottlenecks, overheads, wait-times in the TightVNC encoding implementation and instead only worries about sending very well (and quickly) compressed JPEG data. * A fast proprietary JPEG implemention is used (Intel IPP on x86) instead of the usual libjpeg implementation. TurboJPEG is an interface library, libturbojpeg, provided by the project that achieves this. TurboVNC works very well over LAN and evidently fast Broadband too. When using it with x11vnc in such a situation you may want to dial down the delays, e.g. "-wait 5" and "-defer 5" (or even a smaller setting) to poll and pump things out more quickly. See the instructions in "x11vnc/misc/turbovnc/README" for how to build x11vnc with TurboVNC support. You will also need to download the TurboJPEG software. In brief, the steps look like this: ``` cd x11vnc-x.y.z/x11vnc/misc/turbovnc ./apply_turbovnc cd ../../.. env LDFLAGS='-L/DIR -Xlinker --rpath=/DIR' ./configure make AM_LDFLAGS='-lturbojpeg' ``` where you replace "/DIR" with the directory containing libturbojpeg.so you downloaded separately. If it works out well enough TurboVNC support will be integrated into x11vnc and more of its tuning features will be implemented. Support for TurboVNC in SSVNC viewer has been added as an experiment as well. If you try either one, let us know how it went. There also may be some Linux.i686 and Darwin.i386 x11vnc binaries with TurboVNC support in the misc. bins directory. For other platforms you will need to compile yourself. On relatively cheap and old hardware (Althon64 X2 5000+ / GeForce 6200) x11vnc and SSVNC, both TurboVNC enabled, were able to sustain 13.5 frames/sec (fps) and 15 Megapixels/sec using the VirtualGL supplied OpenGL benchmark program glxspheres. VirtualGL on higher-end hardware can sustain 20-30 fps with the glxspheres benchmark. Potential Slowdown: As we describe elsewhere, unless you use x11vnc with an X server using, say, NVidia proprietary drivers (or a virtual X server like Xvfb or Xdummy, or in ShadowFB mode), then the read rate from the graphics card can be rather slow (e.g. 10 MB/sec) and becomes the bottleneck when using x11vnc over fast networks. Note that all of Xorg's drivers currently (2009) have slow read rates (only proprietary drivers appear to have optimized reads.) So under these (more or less typical) conditions, the speed improvement provided by TurboVNC may only be marginal. Look for this output to see your read rate: ``` 28/02/2009 11:11:07 Autoprobing TCP port 28/02/2009 11:11:07 Autoprobing selected port 5900 28/02/2009 11:11:08 fb read rate: 10 MB/sec 28/02/2009 11:11:08 screen setup finished. ``` A rate of 10 MB/sec means a 1280x1024x24 screen takes 0.5 seconds to read in. TurboVNC compresses that to JPEG in a much shorter time. On the other hand, an NVidia driver may have a read rate of 250 MB/sec and so only takes 0.02 seconds to read the entire screen in. ## Mouse Cursor Shapes ### Q-81: Why isn't the mouse cursor shape (the little icon shape where the mouse pointer is) correct as I move from window to window? On X servers supporting XFIXES or Solaris/IRIX Overlay extensions it is possible for x11vnc to do this correctly. See a few paragraphs down for the answer. Historically, the X11 mouse cursor shape (i.e. little picture: an arrow, X, I-beam, resizer, etc) is one of the few WRITE-only objects in X11. That is, an application can tell the X server what the cursor shape should be when the pointer is in a given window, but a program (like x11vnc) unfortunately cannot read this information. I believe this is because the cursor shape is often downloaded to the graphics hardware (video card), but I could be mistaken. A simple kludge is provided by the "-cursor X" option that changes the cursor when the mouse is on the root background (or any window has the same cursor as the root background.) Note that desktops like GNOME or KDE often cover up the root background, so this won't work for those cases. Also see the "-cursor some" option for additional kludges. Note that as of Aug/2004 on Solaris using the SUN_OVL overlay extension and IRIX, x11vnc can show the correct mouse cursor when the -overlay option is supplied. See this FAQ for more info. Also as of Dec/2004 XFIXES X extension support has been added to allow exact extraction of the mouse cursor shape. XFIXES fixes the problem of the cursor-shape being write-only: x11vnc can now query the X server for the current shape and send it back to the connected viewers. XFIXES is available on recent Linux Xorg based distros and Solaris 10. The only XFIXES issue is the handling of alpha channel transparency in cursors. If a cursor has any translucency then in general it must be approximated to opaque RGB values for use in VNC. There are some situations where the cursor transparency can also handled exactly: when the VNC Viewer requires the cursor shape be drawn into the VNC framebuffer or if you apply a patch to your VNC Viewer to extract hidden alpha channel data under 32bpp. Details can be found here. ### Q-82: When using XFIXES cursorshape mode, some of the cursors look really bad with extra black borders around the cursor and other cruft. How can I improve their appearance? This happens for cursors with transparency ("alpha channel"); regular X cursors (bitmaps) should be correct. Unfortunately x11vnc 0.7 was released with a very poor algorithm for approximating the transparency, which led to the ugly black borders. The problem is as follows: XFIXES allows x11vnc to retrieve the current X server cursor shape, including the alpha channel for transparency. For traditional bitmap cursors the alpha value will be 0 for completely transparent pixels and 255 for completely opaque pixels; whereas for modern, eye-candy cursors an alpha value between 0 and 255 means to blend in the background colors to that degree with the cursor colors. The pixel color blending formula is something like this: Red = Red_cursor * a + Red_background * (1 - a), (where here 0 =< a =< 1), with similar for Green and Blue. The VNC protocol does not currently support an alpha channel in cursors: it only supports regular X bitmap cursors and Rich Cursors that have RGB (Red, Green, Blue) color data, but no "A" = alpha data. So in general x11vnc has to approximate a cursor with transparency to create a Rich Cursor. This is easier said than done: some cursor themes have cursors with complicated drop shadows and other forms of translucency. Anyway, for the x11vnc 0.7.1 release the algorithm for approximating transparency is much improved and hopefully gives decent cursor shapes for most cursor themes and you don't have to worry about it. In case it still looks bad for your cursor theme, there are (of course!) some tunable parameters. The "-alphacut n" option lets you set the threshold "n" (between 0 and 255): cursor pixels with alpha values below n will be considered completely transparent while values equal to or above n will be completely opaque. The default is 240. The "-alphafrac f" option tries to correct individual cursors that did not fare well with the default -alphacut value: if a cursor has less than fraction f (between 0.0 and 1.0) of its pixels selected by the default -alphacut, the threshold is lowered until f of its pixels are selected. The default fraction is 0.33. Finally, there is an option -alpharemove that is useful for themes where many cursors are light colored (e.g. "whiteglass".) XFIXES returns the cursor data with the RGB values pre-multiplied by the alpha value. If the white cursors look too grey, specify -alpharemove to brighten them by having x11vnc divide out the alpha value. One user played with these parameters and reported back: ``` Of the cursor themes present on my system: gentoo and gentoo-blue: alphacut:192 - noalpharemove gentoo-silver: alphacut:127 and alpharemove whiteglass and redglass (presumably also handhelds, which is based heavily on redglass) look fine with the apparent default of alphacut:255. ``` ### Q-83: In XFIXES mode, are there any hacks to handle cursor transparency ("alpha channel") exactly? As of Jan/2005 libvncserver has been modified to allow an alpha channel (i.e. RGBA data) for Rich Cursors. So x11vnc can now send the alpha channel data to libvncserver. However, this data will only be used for VNC clients that do not support the CursorShapeUpdates VNC extension (or have disabled it.) It can be disabled for all clients with the -nocursorshape x11vnc option. In this case the cursor is drawn, correctly blended with the background, into the VNC framebuffer before being sent out to the client. So the alpha blending is done on the x11vnc side. Use the -noalphablend option to disable this behavior (always approximate transparent cursors with opaque RGB values.) The CursorShapeUpdates VNC extension complicates matters because the cursor shape is sent to the VNC viewers supporting it, and the viewers draw the cursor locally. This improves response over slow links. Alpha channel data for these locally drawn cursors is not supported by the VNC protocol. However, in the libvncserver CVS there is a patch to the TightVNC viewer to make this work for CursorShapeUpdates under some circumstances. This hack is outside of the VNC protocol. It requires the screens on both sides to be depth 24 at 32bpp (it uses the extra 8 bits to secretly hide the cursor alpha channel data.) Not only does it require depth 24 at 32bpp, but it also currently requires the client and server to be of the same endianness (otherwise the hidden alpha data gets reset to zero by a libvncserver translation function; we can fix this at some point if there is interest.) The patch is for the TightVNC 1.3dev5 Unix vncviewer and it enables the TightVNC viewer to do the cursor alpha blending locally. The patch code should give an example on how to change the Windows TightVNC viewer to achieve the same thing (send me the patch if you get that working.) This patch is applied to the Enhanced TightVNC Viewer (SSVNC) package we provide. ## Mouse Pointer ### Q-84: Why does the mouse arrow just stay in one corner in my vncviewer, whereas my cursor (that does move) is just a dot? This default takes advantage of a tightvnc extension (CursorShapeUpdates) that allows specifying a cursor image shape for the local VNC viewer. You may disable it with the -nocursor option to x11vnc if your viewer does not have this extension. Note: as of Aug/2004 this should be fixed: the default for non-tightvnc viewers (or ones that do not support CursorShapeUpdates) will be to draw the moving cursor into the x11vnc framebuffer. This can also be disabled via -nocursor. ### Q-85: Can I take advantage of the TightVNC extension to the VNC protocol where Cursor Positions Updates are sent back to all connected clients (i.e. passive viewers can see the mouse cursor being moved around by another viewer)? Use the -cursorpos option when starting x11vnc. A VNC viewer must support the Cursor Positions Updates for the user to see the mouse motions (the TightVNC viewers support this.) As of Aug/2004 -cursorpos is the default. See also -nocursorpos and -nocursorshape. ### Q-86: Is it possible to swap the mouse buttons (e.g. left-handed operation), or arbitrarily remap them? How about mapping button clicks to keystrokes, e.g. to partially emulate Mouse wheel scrolling? You can remap the mouse buttons via something like: -buttonmap 13-31 (or perhaps 12-21.) Also, note that xmodmap(1) lets you directly adjust the X server's button mappings, but in some circumstances it might be more desirable to have x11vnc do it. One user had an X server with only one mouse button(!) and was able to map all of the VNC client mouse buttons to it via: -buttonmap 123-111. Note that the -debug_pointer option prints out much info for every mouse/pointer event and is handy in solving problems. To map mouse button clicks to keystrokes you can use the alternate format where the keystrokes are enclosed between colons like this :: in place of the mouse button digit. For a sequence of keysyms separate them with "+" signs. Look in the include file , or use xev(1), or -debug_keyboard to find the keysym names. Button clicks can also be included in the sequence via the fake keysyms Button1, etc. As an example, suppose the VNC viewer machine has a mouse wheel (these generate button 4 and 5 events), but the machine that x11vnc is run on only has the 3 regular buttons. In normal operation x11vnc will discard the button 4 and 5 events. However, either of the following button maps could possibly be of use emulating the mouse wheel events in this case: ``` -buttonmap 12345-123:Prior::Next: -buttonmap 12345-123:Up+Up+Up::Down+Down+Down: ``` Exactly what keystroke "scrolling" events they should be bound to depends on one's taste. If this method is too approximate, one could consider not using -buttonmap but rather configuring the X server to think it has a mouse with 5 buttons even though the physical mouse does not. (e.g. 'Option "ZAxisMapping" "4 5"'.) Note that when a keysym-mapped mouse button is clicked down this immediately generates the key-press and key-release events (for each keysym in turn if the mapping has a sequence of keysyms.) When the mouse button goes back up nothing is generated. If you include modifier keys like Shift_L instead of key-press immediately followed by key-release the state of the modifier key is toggled (however the initial state of the modifier key is ignored.) So to map the right button to type my name 'Karl Runge' I could use this: ``` -buttonmap 3-:Shift_L+k+Shift_L+a+r+l+space+Shift_L+r+Shift_L+u+n+g+e: ``` (yes, this is getting a little silly.) BTW, Coming the other way around, if the machine you are sitting at does not have a mouse wheel, but the remote machine does (or at least has 5 buttons configured), this key remapping can be useful: ``` -remap Super_R-Button4,Menu-Button5 ``` you just tap those two keys to get the mouse wheel scrolls (this is more useful than the Up and Down arrow keys because a mouse wheel "click" usually gives a multi-line scroll.) ## Keyboard Issues ### Q-87: How can I get my AltGr and Shift modifiers to work between keyboards for different languages? The option -modtweak should help here. It is a mode that monitors the state of the Shift and AltGr Modifiers and tries to deduce the correct keycode to send, possibly by sending fake modifier key presses and releases in addition to the actual keystroke. Update: As of Jul/2004 -modtweak is now the default (use -nomodtweak to get the old behavior.) This was done because it was noticed on newer XFree86 setups even on bland "us" keyboards like "pc104 us" XFree86 included a "ghost" key with both "<" and ">" it. This key does not exist on the keyboard (see this FAQ for more info.) Without -modtweak there was then an ambiguity in the reverse map keysym => keycode, making it so the "<" symbol could not be typed. Also see the FAQ about the -xkb option for a more powerful method of modifier tweaking for use on X servers with the XKEYBOARD extension. When trying to resolve keyboard mapping problems, note that the -debug_keyboard option prints out much info for every keystroke and so can be useful debugging things. Note that for some users, the solution is to disable all of the above, and use -nomodtweak. This is the simplest form of keystroke insertion and it actually solved the problem. Try it if the other options don't help. ### Q-88: When I try to type a "<" (i.e. less than) instead I get ">" (i.e. greater than)! Strangely, typing ">" works OK!! Does your keyboard have a single key with both "<" and ">" on it? Even if it doesn't, your X server may think your keyboard has such a key (e.g. pc105 in the XF86Config file when it should be something else, say pc104.) Short Cut: Try the -xkb or -sloppy_keys options and see if that helps the situation. The discussion below is a bit outdated (e.g. -modtweak is now the default) but it is useful reference for various tricks and so is kept. The problem here is that on the Xserver where x11vnc is run there are two keycodes that correspond to the "<" keysym. Run something like this to see: ``` xmodmap -pk | egrep -i 'KeyCode|less|greater' There are 4 KeySyms per KeyCode; KeyCodes range from 8 to 255. KeyCode Keysym (Keysym) ... 59 0x002c (comma) 0x003c (less) 60 0x002e (period) 0x003e (greater) 94 0x003c (less) 0x003e (greater) ``` That keycode 94 is the special key with both "<" and ">". When x11vnc receives the "<" keysym over the wire from the remote VNC client, it unfortunately maps it to keycode 94 instead of 59, and sends 94 to the X server. Since Shift is down (i.e. you are Shifting the comma key), the X server interprets this as Shifted-94, which is ">". A workaround in the X server configuration is to "deaden" that special key: ``` xmodmap -e "keycode 94 = " ``` However, one user said he had to do this: ``` xmodmap -e "keycode 94 = 0x002c 0x003c" ``` (If the numerical values are different for your setup, substitute the ones that correspond to your display. The above xmodmap scheme can often be used to work around other ambiguous keysym to keycode mappings.) Alternatively, here are some x11vnc options to try to work around the problem: ``` -modtweak ``` and ``` -remap less-comma ``` These are convenient in that they do not modify the actual X server settings. The former (-modtweak) is a mode that monitors the state of the Shift and AltGr modifiers and tries to deduce the correct keycode sequence to send. Since Jul/2004 -modtweak is now the default. The latter (-remap less-comma) is an immediate remapping of the keysym less to the keysym comma when it comes in from a client (so when Shift is down the comma press will yield "<".) See also the FAQ about the -xkb option as a possible workaround using the XKEYBOARD extension. Note that the -debug_keyboard option prints out much info for every keystroke to aid debugging keyboard problems. ### Q-89: Extra Character Inserted, E.g.: When I try to type a "<" (i.e. less than) instead I get "<," (i.e. an extra comma.) This is likely because you press "Shift" then "<" but then released the Shift key before releasing the "<". Because of a keymapping ambiguity the last event "< up" is interpreted as "," because that key unshifted is the comma. This extra character insertion will happen for other combinations of characters: in general it can happen whenever the Shift key is released early. This should not happen in -xkb mode, because it works hard to resolve the ambiguities. If you do not want to use -xkb, try the option -sloppy_keys to attempt a similar type of algorithm. One user had this problem for Italian and German keyboards with the key containing ":" and "." When he typed ":" he would get an extra "." inserted after the ":". The solution was -sloppy_keys. ### Q-90: I'm using an "international" keyboard (e.g. German "de", or Danish "dk") and the -modtweak mode works well if the VNC viewer is run on a Unix/Linux machine with a similar keyboard. But if I run the VNC viewer on Unix/Linux with a different keyboard (e.g. "us") or Windows with any keyboard, I can't type some keys like: "@", "$", "<", ">", etc. How can I fix this? The problem with Windows is it does not seem to handle AltGr well. It seems to fake it up by sending Control_L+Alt_R to applications. The Windows VNC viewer sends those two down keystrokes out on the wire to the VNC server, but when the user types the next key to get, e.g., "@" the Windows VNC viewer sends events bringing the up the Control_L+Alt_R keys, and then sends the "@" keysym by itself. The Unix/Linux VNC viewer on a "us" keyboard does a similar thing since "@" is the Shift of the "2" key. The keysyms Shift and "@" are sent to the VNC server. In both cases no AltGr is sent to the VNC server, but we know AltGr is needed on the physical international keyboard to type a "@". This all worked fine with x11vnc running with the -modtweak option (it figures out how to adjust the Modifier keys (Shift or AltGr) to get the "@".) However it fails under recent versions of XFree86 (and the X.org fork.) These run the XKEYBOARD extension by default and make heavy use of it to handle international keyboards. To make a long story short, on these newer XFree86 setups the traditional X keymap lookup x11vnc uses is no longer accurate. x11vnc can't find the keysym "@" anywhere in the keymapping! (even though it is in the XKEYBOARD extended keymapping.) How to Solve: As of Jul/2004 x11vnc has two changes: * -modtweak (tweak Modifier keys) is now the default (use -nomodtweak to go back to the old way) * there is a new option -xkb to use the XKEYBOARD extension API to do the Modifier key tweaking. The -xkb option seems to fix all of the missing keys: "@", "<", ">", etc.: it is recommended that you try it if you have this sort of problem. Let us know if there are any remaining problems (see the next paragraph for some known problems.) If you specify the -debug_keyboard (aka -dk) option twice you will get a huge amount of keystroke debugging output (send it along with any problems you report.) Update: as of Jun/2005 x11vnc will try to automatically enable -xkb if it appears that would be beneficial (e.g. if it sees any of "@", "<", ">", "[" and similar keys are mapped in a way that needs the -xkb to access them.) To disable this automatic check use -noxkb. Known problems: * One user had to disable a "ghost" Mode_switch key that was causing problems under -xkb. His physical AltGr key was bound to ISO_Level3_Shift (which seems to be the XKEYBOARD way of doing things), while there was a ghost key Mode_switch (which seems to be obsolete) in the mapping as well. Both of these keysyms were bound to Mod5 and x11vnc was unfortunately choosing Mode_switch. From the x11vnc -xkb -dk -dk output it was noted that Mode_switch was attached to keycode 93 (no physical key generates this keycode) while ISO_Level3_Shift was attached to keycode 113. The keycode skipping option was used to disable the ghost key: -skip_keycodes 93 * In implementing -xkb we noticed that some characters were still not getting through, e.g. "~" and "^". This is not really an XKEYBOARD problem. What was happening was the VNC viewer was sending the keysyms asciitilde and asciicircum to x11vnc, but on the X server with the international keyboard those keysyms were not mapped to any keys. So x11vnc had to skip them (Note: as of May/2005 they are added by default see -add_keysyms below.) The way these characters are typically entered on international keyboards is by "dead" (aka "mute") keys. E.g. to enter "~" at the physical display the keysym dead_tilde is pressed and released (this usually involves holding AltGr down while another key is pressed) and then space is pressed. (this can also be used get characters with the "~" symbol on top, e.g. "\E3" by typing "a" instead of space.) What to do? In general the VNC protocol has not really solved this problem: what should be done if the VNC viewer sends a keysym not recognized by the VNC server side? Workarounds can possibly be created using the -remap x11vnc option: ``` -remap asciitilde-dead_tilde,asciicircum-dead_circumflex ``` etc. Use -remap filename if the list is long. Please send us your workarounds for this problem on your keyboard. Perhaps we can have x11vnc adjust automatically at some point. Also see the -add_keysyms option in the next paragraph. Update: for convenience "-remap DEAD" does many of these mappings at once. * To complement the above workaround using the -remap, an option -add_keysyms was added. This option instructs x11vnc to bind any unknown Keysyms coming in from VNC viewers to unused Keycodes in the X server. This modifies the global state of the X server. When x11vnc exits it removes the extra keymappings it created. Note that the -remap mappings are applied first, right when the Keysym is received from a VNC viewer, and only after that would -add_keysyms, or anything else, come into play. Update: -add_keysyms is now on by default. Use -noadd_keysyms to disable. ### Q-91: When typing I sometimes get double, triple, or more of my keystrokes repeated. I'm sure I only typed them once, what can I do? This may be due to an interplay between your X server's key autorepeat delay and the extra time delays caused by x11vnc processing. Short answer: disable key autorepeating by running the command "xset r off" on the Xserver where x11vnc is run (restore via "xset r on") or use the new (Jul/2004) -norepeat x11vnc option. You will still have autorepeating because that is taken care of on your VNC viewer side. Update: as of Dec/2004 -norepeat is now the default. Use -repeat to disable it. Details: suppose you press a key DOWN and it generates changes in large regions of the screen. The CPU and I/O work x11vnc does for the large screen change could be longer than your X server's key autorepeat delay. x11vnc may not get to processing the key UP event until after the screen work is completed. The X server believes the key has been held down all this time, and applies its autorepeat rules. Even without inducing changes in large regions of the screen, this problem could arise when accessing x11vnc via a dialup modem or otherwise high latency link (e.g. > 250 ms latency.) Look at the output of "xset q" for the "auto repeat delay" setting. Is it low (e.g. < 300 ms)? If you turn off autorepeat completely: "xset r off", does the problem go away? The workaround is to manually apply "xset r off" and "xset r on" as needed, or to use the -norepeat (which has since Dec/2004 been made the default.) Note that with X server autorepeat turned off the VNC viewer side of the connection will (nearly always) do its own autorepeating so there is no big loss here, unless someone is also working at the physical display and misses his autorepeating. ### Q-92: The x11vnc -norepeat mode is in effect, but I still get repeated keystrokes!! Are you using x11vnc to log in to an X session via display manager? (as described in this FAQ) If so, x11vnc is starting before your session and it disables autorepeat when you connect, but then after you log in your session startup (GNOME, KDE, ...) could be resetting the autorepeat to be on. Or it could be something inside your desktop trying to be helpful that decides to turn it back on. x11vnc in -norepeat mode will by default reset autorepeat to off 2 times (to help get thru the session startup problem), but it will not continue to battle with things turning autorepeat back on. It will also turn autorepeat off whenever it goes from a state of zero clients to one client. You can adjust the number of resets via "-norepeat N", or use "-norepeat -1" to have it keep resetting it whenever autorepeat gets turned back on when clients are connected. In general you can manually turn autorepeating off by typing "xset r off", or a using desktop utility/menu, or "x11vnc -R norepeat". If something in your desktop is automatically turning it back on you should figure out how to disable that somehow. ### Q-93: After using x11vnc for a while, I find that I cannot type some (or any) characters or my mouse clicks and drags no longer have any effect, or they lead to strange effects. What happened? Probably a modifier key, e.g. Control or Alt is "stuck" in a pressed down state. This happens for VNC in general by the following mechanism. Suppose on the Viewer side desktop there is some hot-key to switch desktops/rooms/spaces, etc. E.g. suppose Alt+LeftArrow moves to the left desktop/room/space. Or suppose an Alt+hotkey combination iconifies a window. This can leave the Alt key pressed down on the remote side. Consider the sequence that happens. The Alt_L key and then the LeftArrow key go down. Since you are inside the viewer the Alt_L key press is sent to the other side (x11vnc) and so it is pressed down in the remote desktop as well. (by "Alt_L" we mean the Alt key on the left-hand side of the keyboard.) Your local desktop (where the VNC Viewer is running) then warps to the new desktop/room/space: Leaving the Alt_L key still pressed down in the remote desktop. If someone is sitting at the desktop, or when you return in the viewer it may be very confusing because the Alt_L is still pressed down but you (or the person sitting at the desktop) do not realize this. Depending on which remote desktop (x11vnc side) is used, it can act very strangely. A quick workaround when you notice this is to press and release all of the Alt, Shift, Control, Windows-Flag, modifier keys to free the pressed one. You need to do this for both the left and right Shift, Alt, Control, etc. keys to be sure. Note that many VNC Viewers try to guard against this when they are notified by the window system that the viewer app has "lost focus". When it receives the "lost focus" event, the viewer sends VNC Key-Release events for all modifier keys that are currently pressed down. This does not always work, however, since it depends on how the desktop manages these "warps". If the viewer is not notified it cannot know it needs to release the modifiers. You can also use the -clear_mods option to try to clear all of the modifier keys at x11vnc startup. You will still have to be careful that you do not leave the modifier key pressed down during your session. It is difficult to prevent this problem from occurring (short of using -remap to prevent sending all of the problem modifier keys, which would make the destkop pretty unusable.) During a session these x11vnc remote control commands can also help: ``` x11vnc -R clear_mods x11vnc -R clear_keys x11vnc -R clear_locks x11vnc -R clear_all ``` A similar problem can occur if you accidentally press the Caps_Lock or Num_Lock down. When these are locked on the remote side it can sometimes lead to strange desktop behavior (e.g. cannot drag or click on windows.) As above you may not notice this because the lock isn't down on the local (Viewer) side. See this FAQ on lock keys problem. These options may help avoid the problem: -skip_lockkeys and -capslock. See also -clear_all. ### Q-94: The machine where I run x11vnc has an AltGr key, but the local machine where I run the VNC viewer does not. Is there a way I can map a local unused key to send an AltGr? How about a Compose key as well? Something like "-remap Super_R-Mode_switch" x11vnc option may work. Note that Super_R is the "Right Windoze(tm) Flaggie" key; you may want to choose another. The -debug_keyboard option comes in handy in finding keysym names (so does xev(1).) For Compose how about "-remap Menu-Multi_key" (note that Multi_key is the official name for Compose.) To do both at the same time: "-remap Super_R-Mode_switch,Menu-Multi_key" or use "-remap filename" to specify remappings from a file. ### Q-95: I have a Sun machine I run x11vnc on. Its Sun keyboard has just one Alt key labelled "Alt" and two Meta keys labelled with little diamonds. The machine where I run the VNC viewer only has Alt keys. How can I send a Meta keypress? (e.g. emacs needs this) Here are a couple ideas. The first one is to simply use xmodmap(1) to adjust the Sun X server. Perhaps xmodmap -e "keysym Alt_L = Meta_L Alt_L" will do the trick. (there are other ways to do it, one user used: xmodmap -e "keycode 26 = Meta_L" for his setup.) Since xmodmap(1) modifies the X server mappings you may not want to do this (because it affects local work on that machine.) Something like the -remap Alt_L-Meta_L to x11vnc may be sufficient for ones needs, and does not modify the X server environment. Note that you cannot send Alt_L in this case, maybe -remap Super_L-Meta_L would be a better choice if the Super_L key is typically unused in Unix. ### Q-96: Running x11vnc on HP-UX I cannot type "#" I just get a "3" instead. One user reports this problem on HP-UX Rel_B.11.23. The problem was traced to a strange keyboard mapping for the machine (e.g. xmodmap -pk output) that looked like: ``` ... 039 2 at at at ... 047 3 numbersign numbersign numbersign ``` and similar triple mappings (with two in the AltGr/Mode_switch group) of a keysum to a single keycode. Use the -nomodtweak option as a workaround. You can also use xmodmap to correct these mappings in the server, e.g.: ``` xmodmap -e "keycode 47 = 3 numbersign" ``` Also, as of Feb/2007, set the environment variable MODTWEAK_LOWEST=1 (either in your shell or via "-env MODTWEAK_LOWEST=1" option) to handle these mappings better. ### Q-97: Can I map a keystroke to a mouse button click on the remote machine? This can be done directly in some X servers using AccessX and Pointer_EnableKeys, but is a bit awkward. It may be more convenient to have x11vnc do the remapping. This can be done via the -remap option using the fake "keysyms" Button1, Button2, etc. as the "to" keys (i.e. the ones after the "-") As an example, consider a laptop where the VNC viewer is run that has a touchpad with only two buttons. It is difficult to do a middle button "paste" because (using XFree86/Xorg Emulate3Buttons) you have to click both buttons on the touch pad at the same time. This remapping: -remap Super_R-Button2 maps the Super_R "flag" key press to the Button2 click, thereby making X pasting a bit easier. Note that once the key goes down, the button down and button up events are generated immediately on the x11vnc side. When the key is released (i.e. goes up) no events are generated. ### Q-98: How can I get Caps_Lock to work between my VNC viewer and x11vnc? This is a little tricky because it is possible to get the Caps_Lock state out of sync between your viewer-side machine and the x11vnc-side X server. For best results, we recommend not ever letting the Caps_Lock keypresses be processed by x11vnc. That way when you press Caps_Lock in the viewer your local machine goes into the Caps_Lock on state and sends keysym "A" say when you press "a". x11vnc will then fake things up so that Shift is held down to generate "A". The -skip_lockkeys option should help to accomplish this. For finer grain control use something like: "-remap Caps_Lock-None". Also try the -nomodtweak and -capslock options. Another useful option that turns off any Lock keys on the remote side at startup and end is the -clear_all option. During a session you can run these remote control commands to modify the Lock keys: x11vnc -R clear_locks x11vnc -R clear_all the former will try to unset any Lock keys, the latter will do same and also try to make it so no key is pressed down (e.g. "stuck" Alt_L, etc.) ## Screen Related Issues and Features ### Q-99: The remote display is larger (in number of pixels) than the local display I am running the vncviewer on. I don't like the vncviewer scrollbars, what I can do? vncviewer has a option (usually accessible via F8 key or -fullscreen option) for vncviewer to run in full screen, where it will automatically scroll when the mouse is near the edge of the current view. For quick scrolling, also make sure Backing Store is enabled on the machine vncviewer is run on. (XFree86/Xorg disables it by default for some reason, add Option "backingstore" to XF86Config on the vncviewer side.) BTW, contact me if you are having problems with vncviewer in fullscreen mode with your window manager (i.e. no keyboard response.) I have a workaround for vncviewer using XGrabServer(). There may also be scaling viewers out there (e.g. TightVNC or UltraVNC on Windows) that automatically shrink or expand the remote framebuffer to fit the local display. Especially for hand-held devices. See also the next FAQ on x11vnc scaling. ### Q-100: Does x11vnc support server-side framebuffer scaling? (E.g. to make the desktop smaller.) As of Jun/2004 x11vnc provides basic server-side scaling. It is a global scaling of the desktop, not a per-client setting. To enable it use the "-scale fraction" option. "fraction" can either be a floating point number (e.g. -scale 0.75) or the alternative m/n fraction notation (e.g. -scale 3/4.) Note that if fraction is greater than one the display is magnified. Extra resources (CPU, memory I/O, and memory) are required to do the scaling. If the machine is slow where x11vnc is run with scaling enabled, the interactive response can be unacceptable. OTOH, if run with scaling on a fast machine the performance degradation is usually not a big issue or even noticeable. It may help to compile x11vnc with compiler option -O3 or -O4 to speed up the scaling code. Set the CFLAGS env. var. before running configure. Also, if you just want a quick, rough "thumbnail" of the display you can append ":nb" to the fraction to turn on "no blending" mode. E.g.: "-scale 1/3:nb" Fonts will be difficult to read, but the larger features will be recognizable. BTW, "no blending" mode is forced on when scaling 8bpp PseudoColor displays (because blending an indexed colormap is a bad idea and leads to random colors, use :fb to force it on.) One can also use the ":nb" with an integer scale factor (say "-scale 2:nb") to use x11vnc as a screen magnifier for vision impaired applications. Since with integer scale factors the framebuffers become huge and scaling operations time consuming, be sure to use ":nb" for the fastest response. In general for a scaled display if you are using a TightVNC viewer you may want to turn off jpeg encoding (e.g. vncviewer -nojpeg host:0.) There appears to be a noise enhancement effect, especially for regions containing font/text: the scaling can introduce some pixel artifacts that evidently causes the tight encoding algorithm to incorrectly detect the regions as image data and thereby introduce additional pixel artifacts due to the lossiness of the jpeg compression algorithm. Experiment to see if -nojpeg vncviewer option improves the readability of text when using -scale to shrink the display size. Also note that scaling may actually slow down the transfer of text regions because after being scaled they do not compress as well. (this can often be a significant slowdown, e.g. 10X.) Another issue is that it appears VNC viewers require the screen width to be a multiple of 4. When scaling x11vnc will round the width to the nearest multiple of 4. To disable this use the ":n4" sub option (like ":nb" in the previous paragraph; to specify both use a comma: ":nb,n4", etc.) If one desires per-client scaling for something like 1:1 from a workstation and 1:2 from a smaller device (e.g. handheld), currently the only option is to run two (or more) x11vnc processes with different scalings listening on separate ports (-rfbport option, etc.) Update: As of May/2006 x11vnc also supports the UltraVNC server-side scaling. This is a per-client scaling by factors 1/2, 1/3, ... and so may be useful for PDA's ("-scale 1/2", etc. will give similar results except that it applies to all clients.) You may need to supply "-rfbversion 3.6" for this to be recognized by UltraVNC viewers. BTW, whenever you run two or more x11vnc's on the same X display and use the GUI, then to avoid all of the x11vnc's simultaneously answering the gui you will need to use something like "-connect file1 -gui ..." with different connect files for each x11vnc you want to control via the gui (or remote-control.) The "-connect file1" usage gives separate communication channels between a x11vnc process and the gui process. Otherwise they all share the same X property channels: VNC_CONNECT and X11VNC_REMOTE. Update: As of Mar/2005 x11vnc now scales the mouse cursor with the same scale factor as the screen. If you don't want that, use the "-scale_cursor frac" option to set the cursor scaling to a different factor (e.g. use "-scale_cursor 1" to keep the cursor at its natural unscaled size.) ### Q-101: Does x11vnc work with Xinerama? (i.e. multiple monitors joined together to form one big, single screen.) Yes, it should generally work because it simply polls the big effective screen. If the viewing-end monitor is not as big as the remote Xinerama display, then the vncviewer scrollbars, etc, will have to be used to pan across the large area. However one user started two x11vnc's, one with "-clip 1280x1024+0+0" and the other with "-clip 1280x1024+1280+0" to split the big screen into two and used two VNC viewers to access them. As of Jun/2008: Use "-clip xinerama0" to clip to the first xinerama sub-screen (if xinerama is active.) xinerama1 for the 2nd sub-screen, etc. This way you don't need to figure out the WxH+X+Y of the desired xinerama sub-screen. screens are sorted in increasing distance from the (0,0) origin (I.e. not the Xserver's order.) There are a couple potential issues with Xinerama however. If the screen is not rectangular (e.g. 1280x1024 and 1024x768 monitors joined together), then there will be "non-existent" areas on the screen. The X server will return "garbage" image data for these areas and so they may be distracting to the viewer. The -blackout x11vnc option allows you to blacken-out rectangles by manually specifying their WxH+X+Y geometries. If your system has the libXinerama library, the -xinerama x11vnc option can be used to have it automatically determine the rectangles to be blackened out. (Note on 8bpp PseudoColor displays the fill color may not be black.) Update: -xinerama is now on by default. Some users have reported that the mouse does not behave properly for their Xinerama display: i.e. the mouse cannot be moved to all regions of the large display. If this happens try using the -xwarppointer option. This instructs x11vnc to fake mouse pointer motions using the XWarpPointer function instead of the XTestFakeMotionEvent XTEST function. (This may be due to a bug in the X server for XTEST when Xinerama is enabled.) Update: As of Dec/2006 -xwarppointer will be applied automatically if Xinerama is detected. To disable use: -noxwarppointer ### Q-102: Can I use x11vnc on a multi-headed display that is not Xinerama (i.e. separate screens :0.0, :0.1, ... for each monitor)? You can, but it is a little bit awkward: you must start separate x11vnc processes for each screen, and on the viewing end start up separate VNC viewer processes connecting to them. e.g. on the remote end: ``` x11vnc -display :0.0 -bg -q -rfbport 5900 x11vnc -display :0.1 -bg -q -rfbport 5901 ``` (this could be automated in the display manager Xsetup for example) and then on the local machine where you are sitting: ``` vncviewer somehost:0 & vncviewer somehost:1 & ``` Note: if you are running on Solaris 8 or earlier you can easily hit up against the maximum of 6 shm segments per process (for Xsun in this case) from running multiple x11vnc processes. You should modify /etc/system as mentioned in another FAQ to increase the limit. It is probably also a good idea to run with the -onetile option in this case (to limit each x11vnc to 3 shm segments), or even -noshm to use no shm segments. ### Q-103: Can x11vnc show only a portion of the display? (E.g. for a special purpose application or a very large screen.) As of Mar/2005 x11vnc has the "-clip WxH+X+Y" option to select a rectangle of width W, height H and offset (X, Y). Thus the VNC screen will be the clipped sub-region of the display and be only WxH in size. One user used -clip to split up a large Xinerama screen into two more managable smaller screens. This also works to view a sub-region of a single application window if the -id or -sid options are used. The offset is measured from the upper left corner of the selected window. ### Q-104: Does x11vnc support the XRANDR (X Resize, Rotate and Reflection) extension? Whenever I rotate or resize the screen x11vnc just seems to crash. As of Dec/2004 x11vnc supports XRANDR. You enable it with the -xrandr option to make x11vnc monitor XRANDR events and also trap X server errors if the screen change occurred in the middle of an X call like XGetImage. Once it traps the screen change it will create a new framebuffer using the new screen. If the connected vnc viewers support the NewFBSize VNC extension (Windows TightVNC viewer and RealVNC 4.0 windows and Unix viewers do) then the viewer will automatically resize. Otherwise, the new framebuffer is fit as best as possible into the original viewer size (portions of the screen may be clipped, unused, etc.) For these viewers you can try the -padgeom option to make the region big enough to hold all resizes and rotations. We have fixed this problem for the TightVNC Viewer on Unix: SSVNC If you specify "-xrandr newfbsize" then vnc viewers that do not support NewFBSize will be disconnected before the resize. If you specify "-xrandr exit" then all will be disconnected and x11vnc will terminate. ### Q-105: Independent of any XRANDR, can I have x11vnc rotate and/or reflect the screen that the VNC viewers see? (e.g. for a handheld whose screen is rotated 90 degrees.) As of Jul/2006 there is the -rotate option allow this. E.g's: "-rotate +90", "-rotate -90", "-rotate x", etc. ### Q-106: Why is the view in my VNC viewer completely black? Or why is everything flashing around randomly? See the next FAQ for a possible explanation. ### Q-107: I use Linux Virtual Terminals (VT's) to implement 'Fast User Switching' between users' sessions (e.g. Betty is on Ctrl-Alt-F7, Bobby is on Ctrl-Alt-F8, and Sid is on Ctrl-Alt-F1: they use those keystrokes to switch between their sessions.) How come the view in a VNC viewer connecting to x11vnc is either completely black or otherwise all messed up unless the X session x11vnc is attached to is in the active VT? This seems to have to do with how applications (the X server processes in this case) must "play nicely" if they are not on the active VT (sometimes called VC for virtual console.) That is, they should not read from the keyboard or mouse or manage the video display unless they have the active VT. Given that it appears the XGetImage() call must ultimately retrieve the framebuffer data from the video hardware itself, it would make sense x11vnc's polling wouldn't work unless the X session had active control of the VT. There does not seem to be an easy way to work around this. Even xwd(1) doesn't work in this case (try it.) Something would need to be done at a lower level, say in the XFree86/Xorg X server. Also, using the Shadow Framebuffer (a copy of the video framebuffer is kept in main memory) does not appear to fix the problem. If no one is sitting at the workstation and you just want to remotely switch the VT over to the one associated with your X session (so x11vnc can poll it correctly), one can use the chvt(1) command, e.g. "chvt 7" for VT #7. ### Q-108: I am using x11vnc where my local machine has "popup/hidden taskbars" and the remote display where x11vnc runs also has "popup/hidden taskbars" and they interfere and fight with each other. What can I do? When you move the mouse to the edge of the screen where the popups happen, the taskbars interfere with each other in strange ways. This sometimes happens where the local machine is GNOME or Mac OS X and the remote machine is GNOME. Is there a way to temporarily disable one or both of these magic desktop taskbars? One x11vnc user suggests: it should be straightforward to right mouse click on the task bar panel, and uncheck "enable auto-hide" from the panel properties dialog box. This will make the panel always visible. ### Q-109: Help! x11vnc and my KDE screensaver keep switching each other on and off every few seconds. This is a new (Jul/2006) problem seen, say, on the version of KDE that is shipped with SuSE 10.1. It is not yet clear what is causing this... If you move the mouse through x11vnc the screensaver shuts off like it should but then a second or two after you stop moving the mouse the screensaver snaps back on. This may be a bug in kdesktop_lock. For now the only workaround is to disable the screensaver. You can try using another one such as straight xscreensaver (see the instructions here for how to disable kdesktop_lock.) If you have more info on this or see it outside of KDE please let us know. Update: It appears this is due to kdesktop_lock enabling the screen saver when the Monitor is in DPMS low-power state (e.g. standby, suspend, or off.) In Nov/2006 the x11vnc -nodpms option was added as a workaround. Normally it is a good thing that the monitor powers down (since x11vnc can still poll the framebuffer in this state), but if you experience the kdesktop_lock problem you can specify the "-nodpms" option to keep the Monitor out of low power state while VNC clients are connected. This is basically the same as typing "xset dpms force on" periodically. (if you don't want to do these things just disable the screensaver.) Feel free to file a bug against kdesktop_lock with KDE. ### Q-110: I am running the compiz 3D window manager (or beryl, MythTv, Google Earth, or some other OpenGL app) and I do not get screen updates in x11vnc. This appears to be because the 3D OpenGL/GLX hardware screen updates do not get reported via the XDAMAGE mechanism. So this is a bug in compiz/beryl or XDAMAGE/Xorg or the (possibly 3rd party) video card driver. As a workaround apply the -noxdamage option. As of Feb/2007 x11vnc will try to autodetect the problem and disable XDAMAGE if is appears to be missing a lot of updates. But if you know you are using compiz you might as well always supply -noxdamage. Thanks to this user who reported the problem and discovered the workaround. A developer for MiniMyth reports that the 'alphapulse' tag of the theme G.A.N.T. can also cause problems, and should be avoided when using VNC. Please report a bug or complaint to Beryl/Compiz and/or Xorg about this: running x11vnc with -noxdamage disables a nice improvement in responsiveness (especially for typing) and also leads to unnecessary CPU and memory I/O load due to the extra polling. Update: as of May/2010 NVIDIA may have fixed this problem in their proprietary drivers. See the NVIDIA Release Notes. (look for 'x11vnc'.) ### Q-111: Can I use x11vnc to view my VMWare session remotely? Yes, since VMWare usually runs as an X application you can view it via x11vnc in the normal way. Note that VMWare has several viewing modes: * Normal X application window (with window manager frame) * Quick-Switch mode (with no window manager frame) * Fullscreen mode The way VMWare does Fullscreen mode on Linux is to display the Guest desktop in a separate Virtual Terminal (e.g. VT 8) (see this FAQ on VT's for background.) Unfortunately, this Fullscreen VT is not an X server. So x11vnc cannot access it (however, see this discussion of -rawfb for a possible workaround.) x11vnc works fine with "Normal X application window" and "Quick-Switch mode" because these use X. Update: It appears the in VMWare 5.x the Fullscreen mode is X, so x11vnc access does work. One user reports he left his machine with VMWare in the Fullscreen mode, and even though his X session wasn't in the active VT, he could still connect x11vnc to the X session and pass the keystrokes Ctrl-Alt (typing "blind") to the VMWare X app. This induced VMWare to switch out of Fullscreen into Normal X mode and he could continue working in the Guest desktop remotely. Aside: Sometimes it is convenient (for performance, etc.) to start VMWare in its own X session using startx(1). This can be used to have a minimal window manger (e.g. twm or even no window manager), to improve response. One can also cut the display depth (e.g. to 16bpp) in this 2nd X session to improve video performance. This 2nd X session emulates Fullscreen mode to some degree and can be viewed via x11vnc as long as the VMWare X session is in the active VT. Also note that with a little bit of playing with "xwininfo -all -children" output one can extract the (non-toplevel) window-id of the of the Guest desktop only when VMWare is running as a normal X application. Then one can export just the guest desktop (i.e. without the VMWare menu buttons) by use of the -id windowid option. The caveats are the X session VMWare is in must be in the active VT and the window must be fully visible, so this mode is not terribly convenient, but could be useful in some circumstances (e.g. running VMWare on a very powerful server machine in a server room that happens to have a video card, (but need not have a monitor, Keyboard or mouse).) ## Exporting non-X11 devices via VNC ### Q-112: Can non-X devices (e.g. a raw framebuffer) be viewed (and even controlled) via VNC with x11vnc? As of Apr/2005 there is support for this. Two options were added: "-rawfb string" (to indicate the raw frame buffer device, file, etc. and its parameters) and "-pipeinput command" (to provide an external program that will inject or otherwise process mouse and keystroke input.) Some useful -pipeinput schemes, VID, CONSOLE, and UINPUT, have since been built into x11vnc for convenience. This non-X mode for x11vnc is somewhat experimental because it is so removed in scope from the intended usage of the tool. Incomplete attempt is made to make all of the other options consistent with non-X framebuffer polling. So all of the X-related options (e.g. -add_keysyms, -xkb) are just ignored or may cause an error if used. Be careful applying such an option via remote control. The format for the -rawfb string is: ``` -rawfb :@xx[-][://][+] ``` There are also some useful aliases (e.g. "console".) Some examples: ``` -rawfb shm:210337933@800x600x32:ff/ff00/ff0000 -rawfb map:/dev/fb0@1024x768x16 -rawfb map:/tmp/Xvfb_screen0@640x480x8+3232 -rawfb file:/tmp/my.pnm@250x200x24+37 -rawfb file:/dev/urandom@128x128x8 -rawfb snap:/dev/video0@320x240x24 -24to32 -rawfb console -rawfb vt2 -rawfb video -rawfb setup:mycmd.sh ``` So the type can be "shm" for shared memory objects, and "map" or "file" for file objects. "map" uses mmap(2) to map the file into memory and is preferred over "file" (that uses the slower lseek(2) access method.) Only use file if map isn't working. BTW, "mmap" is an alias for "map" and if you do not supply a type and the file exists, map is assumed (see the -help output and below for some exceptions to this.) The "snap:" setting applies the -snapfb option with "file:" type reading (this is useful for exporting webcams or TV tuner video; see the next FAQ for more info.) Also, if the string is of the form "setup:cmd" then cmd is run and the first line of its output retrieved and used as the rawfb string. This allows initializing the device, determining WxHxB, etc. The object will be the numerical shared memory id for the case of shm. The idea here is some other program has created this shared memory segment and periodically updates it with new framebuffer data. x11vnc polls the area for changes. See shmat(2) and ipcs(8) for more info. The ipcs command will list current shared memory segments on the system. Sometimes you can snoop on a program's framebuffer it did not expect you would be polling! The object will be the path to the regular or character special file for the cases of map and file. The idea here is that in the case of a regular file some other program is writing/updating framebuffer image data to it. In the case of a character special (e.g. /dev/fb0) it is the kernel that is "updating" the framebuffer data. In most cases x11vnc needs to be told the width, height, and number of bits per pixel (bpp) of the framebuffer. This is the @WxHxB field. For the case of the Linux framebuffer device, /dev/fb0, the fbset(8) may be of use (but may not always be accurate for what is currently viewable.) In general some guessing may be required, especially for the bpp. Update: in "-rawfb console" mode x11vnc will use the linuxfb API to try to guess (it is still not always accurate.) Also try "-rawfb vtN" (on x11vnc 0.9.7 and later) for the N-th Linux text console (aka virtual terminal.) If the number of Bytes Per Line is not WxHxB/8 (i.e. the framebuffer lines are padded) you can specify this information after WxHxB via "-BPL", e.g. @800x600x16-2048 Based on the bpp x11vnc will try to guess the red, green, and blue masks (these indicate which bits correspond to each color.) It if gets it wrong you can specify them manually via the optional ":R/G/B" field. E.g. ":0xff0000/0x00ff00/0x0000ff" (this is the default for 32bpp.) Finally, the framebuffer may not begin at the beginning of the memory object, so use the optional "+offset" parameter to indicate where the framebuffer information starts. So as an example, the Xvfb virtual framebuffer has options -shmem and -fbdir for exporting its virtual screen to either shm or a mapped file. The format of these is XWD and so the initial header should be skipped. BTW, since XWD is not strictly RGB the view will only be approximate, but usable. Of course for the case of Xvfb x11vnc can poll it much better via the X API, but you get the idea. By default in -rawfb mode x11vnc will actually close any X display it happened to open. This is basically to shake out bugs (e.g it will crash rather than mysteriously interacting with the X display.) If you want x11vnc to keep the X display open while polling the raw framebuffer prefix a "+" sign at the beginning of the string (e.g. +file:/dev/urandom@64x64x8) This could be convenient for keeping the remote control channel active (it uses X properties.) The "-connect /path/to/file" mechanism could also be used for remote control to avoid the X property channel. Rare usage, but if you also supply -noviewonly in this "+" mode then the mouse and keyboard input are still sent to the X display, presumably for doing something amusing with /dev/fb... Interesting Devices:. Here are some aliases for interesting device files that can be polled via -rawfb: ``` -rawfb console /dev/fb0 Linux Console -rawfb vt2 /dev/vcsa2 Linux Console (e.g. virtual terminal #2) -rawfb video /dev/video0 Video4Linux Capture device -rawfb rand /dev/urandom Random Bytes -rawfb null /dev/zero Zero Bytes (black screen) ``` The Linux console, /dev/fb0, etc needs to have its driver enabled in the kernel. Some of the drivers are video card specific and accelerated. The console is either the Text consoles (usually tty1-tty6), or X graphical display (usually starting at tty7.) In addition to the text console other graphical ones may be viewed and interacted with as well, e.g. DirectFB or SVGAlib apps, VMWare non-X fullscreen, or Qt-embedded apps (PDAs/Handhelds.) By default the pipeinput mechanisms UINPUT and CONSOLE (keystrokes only) are automatically attempted in this mode under "-rawfb console". The Video4Linux Capture device, /dev/video0, etc is either a Webcam or a TV capture device and needs to have its driver enabled in the kernel. See this FAQ for details. If specified via "-rawfb Video" then the pipeinput method "VID" is applied (it lets you change video parameters dynamically via keystrokes.) The last two, /dev/urandom and /dev/zero are just for fun, but are also useful in testing. All of the above -rawfb options are just for viewing the raw framebuffer (although some of the aliases do imply keystroke and mouse pipeinput methods.) That may be enough for certain applications of this feature (e.g. suppose a video camera mapped its framebuffer into memory and you just wanted to look at it via VNC.) To handle the pointer and keyboard input from the viewer users the "-pipeinput cmd" option was added to indicate a helper program to process the user input. The input is streamed to it and looks something like this: ``` Pointer 1 205 257 0 None Pointer 1 198 253 0 None Pointer 1 198 253 1 ButtonPress-1 Pointer 1 198 253 0 ButtonRelease-1 Pointer 1 198 252 0 None Keysym 1 1 119 w KeyPress Keysym 1 0 119 w KeyRelease Keysym 1 1 65288 BackSpace KeyPress Keysym 1 0 65288 BackSpace KeyRelease Keysym 1 1 112 p KeyPress Keysym 1 0 112 p KeyRelease ``` Run "-pipeinput tee:/bin/cat" to get a description of the format. Note that the -pipeinput option is independent of -rawfb mode and so may have some other interesting uses. The "tee:" prefix means x11vnc will both process the user input and pipe it to the command. The default is to just pipe it to the -pipeinput command. Note the -pipeinput helper program could actually control the raw framebuffer. In the libvncserver CVS a simple example program x11vnc/misc/slide.pl is provided that demonstrates a simple jpeg "slideshow" application. Also the builtin "-pipeinput VID" mode does this for webcams and TV capture devices (/dev/video0.) The -pipeinput program is run with these environment variables set: X11VNC_PID, X11VNC_PROG, X11VNC_CMDLINE, X11VNC_RAWFB_STR to aid its knowing what is up. Another example provided in libvncserver CVS is a script to inject keystrokes into the Linux console (e.g. the virtual consoles: /dev/tty1, /dev/tty2, etc) in x11vnc/misc/vcinject.pl. It is based on the vncterm/LinuxVNC.c program also in the libvncserver CVS. So to view and interact with VT #2 (assuming it is the active VT) one can run something like: ``` x11vnc -rawfb map:/dev/fb0@1024x768x16 -pipeinput './vcinject.pl 2' ``` This assumes your Linux framebuffer device (/dev/fb0) is properly configured. See fbset(8) and other documentation. Try "file:/dev/fb0@WxHxB" as a last resort. Starting with x11vnc 0.8.1, the above VT injection is built in, as well as WxHxB determination. Just use something like: ``` x11vnc -rawfb console ``` this will try to guess the active virtual console (via /dev/tty0) and also the /dev/fb0 WxHxB and rgb masks automatically. Use, e.g., "-rawfb console3" to force the VT number. This input method can be used generally via "-pipeinput CONSOLE". Also starting with x11vnc 0.8.2 the "-pipeinput UINPUT" mode is tried first (it does both keyboard and mouse input) and then falls back to CONSOLE mode if it is not available. Here is the -help output for this mode: ``` If the rawfb string begins with "console" the framebuffer device /dev/fb0 is opened (this requires the appropriate kernel modules to be installed) and so is /dev/tty0. The latter is used to inject keystrokes (not all are supported, but the basic ones are.) You will need to be root to inject keystrokes. /dev/tty0 refers to the active VT, to indicate one explicitly, use "console2", etc. using the VT number. If the Linux version seems to be 2.6 or later and the "uinput" module appears to be present, then the uinput method will be used instead of /dev/ttyN. uinput allows insertion of BOTH keystrokes and mouse input and so it preferred when accessing graphical (e.g. Qt-embedded) linux console apps. See -pipeinput UINPUT below for more information on this mode (you may want to also use the -nodragging and -cursor none options.) Use "console0", etc or -pipeinput CONSOLE to force the /dev/ttyN method. Note you can change VT remotely using the chvt(1) command. Sometimes switching out and back corrects the framebuffer state. To skip input injecting entirely use "consolex". The string "/dev/fb0" (1, etc) can be used instead of "console". This can be used to specify a different framebuffer device, e.g. /dev/fb1. As a shortcut the "/dev/" can be dropped. If the name is something nonstandard, use "console:/dev/foofb" If you do not want x11vnc to guess the framebuffer's WxHxB and masks automatically (sometimes the kernel gives inaccurate information), specify them with a @WxHxB at the end of the string. ``` The above is just an example of what can be done. Note that if you really want to view and interact with the Linux Text console it is better to use the more accurate and faster LinuxVNC program. The advantage x11vnc -rawfb might have is that it can allow interaction with a non-text application, e.g. one based on SVGAlib or Qt-embedded Also, for example the VMWare Fullscreen mode is actually viewable under -rawfb and can be interacted with if uinput is enabled. If the Linux uinput driver is available then full keystroke and mouse input into the Linux console can be performed. You may be able to enable uinput via commands like these: ``` modprobe uinput mknod /dev/input/uinput c 10 223 ``` The -rawfb and -pipeinput features are intended to help one creatively "get out of a jam" (say on a legacy or embedded device) where X is absent or doesn't work properly. Feedback and bug reports are welcome. For more control and less overhead use libvncserver in your own C program that passes the framebuffer to libvncserver. ### Q-113: Can I export the Linux Console (Virtual Terminals) via VNC using x11vnc? Yes, you may need to be root to access the devices that make up the linux console. To access the active Linux console via the computer's framebuffer try something like: ``` x11vnc -rawfb console x11vnc -rawfb console2 ``` These will try to access the framebuffer through /dev/fb (or /dev/fb0, etc.) and if it succeeds it will show any text or graphics that is currently displayed. Keystrokes will be injected via the device /dev/tty0 (to force an explicit virtual terminal append a number, e.g. "console2" to select /dev/tty2.) If your Linux system does not have a framebuffer device (/dev/fb) you can get one by adding, e.g., vga=0x31B boot parameter. This enables the VGA framebuffer device at 1280x1024x24. 0x317 gives 1024x768x16, etc. You can also enable a Linux framebuffer device by modprobing a framebuffer driver specific to your video card. Note that this "-rawfb console" mode shows the contents of the hardware framebuffer, and so will show whatever is on the screen. It has no concept of Virtual Terminals WRT what there is to view, it always shows the active virtual terminal. Another mode is specific to the Linux text Virtual Terminals, it shows their text and colors (but no graphics) regardless of whether it is the active VT or not. It is available on x11vnc 0.9.7 and later. Enable this mode like this: ``` x11vnc -rawfb vt x11vnc -rawfb vt2 ``` The former will select the active one, the latter the 2nd VT. x11vnc implements this mode by opening the current console text file "/dev/vcsa2" instead of "/dev/fb". In this way it provides the basic functionality of the LibVNCServer LinuxVNC program. The vt mode can be a useful way to try to get a machine's X server working remotely, e.g. you edit /etc/X11/xorg.conf and then type startx (or similar, e.g. gdm) in the virtual terminal. A 2nd x11vnc could be used to see if the X server is now working correctly. ### Q-114: Can I export via VNC a Webcam or TV tuner framebuffer using x11vnc? Yes, this is possible to some degree with the -rawfb option. There is no X11 involved: snapshots from the video capture device are used for the screen image data. See the previous FAQ on -rawfb for background. For best results, use x11vnc version 0.8.1 or later. Roughly, one would do something like this: ``` x11vnc -rawfb snap:/dev/video@320x240x32 ``` This requires that the system allows simple read(2) access to the video device. This is true for video4Linux on Linux kernel 2.6 and later (it won't work for 2.4, you'll need a separate program to snapshot to a file that you point -rawfb to; ask me if it is not clear what to do.) The "snap:" enforces -snapfb mode which appears to be necessary. The read pointer for video capture devices cannot be repositioned (which would be needed for scanline polling), but you can read a full frame of data from the device. On Linux, if the Video4Linux API is present or the v4l-info(1) program (related to xawtv) exists in in PATH, then x11vnc can be instructed to try it to determine the -rawfb WxHxB parameters for you automatically. In this case one would just type: ``` x11vnc -rawfb video ``` or "-rawfb video1" for the 2nd video device, etc. x11vnc has also been extended to use the Video4Linux API over v4l-info if it is available at build time. This enables setting parameters (e.g. size and brightness) via x11vnc. See the description below. Without Video4Linux you will need to initialize the settings of the video device using something like xawtv or spcaview (and then hope the settings persist until x11vnc reopens the device.) Many video4linux drivers tend to set the framebuffer to be 24bpp (as opposed to 32bpp.) Since this can cause problems with VNC viewers, etc, the -24to32 option will be automatically imposed when in 24bpp. Note that by its very nature, video capture involves rapid change in the framebuffer. This is especially true for cameras where slight wavering in brightness is always happening. This can lead to much network bandwidth consumption for the VNC traffic and also local CPU and I/O resource usage. You may want to experiment with "dialing down" the framerate via the -wait, -slow_fb, or -defer options. Decreasing the window size and bpp also helps. Setting Camera/Tuner parameters via x11vnc: There is also some support for setting parameters of the capture device. This is done via "-rawfb video:". This could be useful for unattended startup at boottime, etc. Here is the -help description: ``` A more sophisticated video device scheme allows initializing the device's settings using: -rawfb video: The prefix could also be, as above, e.g. "video1:" to specify the device file. The v4l API must be available for this to work. Otherwise, you will need to try to initialize the device with an external program, e.g. xawtv, spcaview, and hope they persist when x11vnc re-opens the device. is a comma separated list of key=value pairs. The device's brightness, color, contrast, and hue can be set to percentages, e.g. br=80,co=50,cn=44,hu=60. The device filename can be set too if needed (if it does not start with "video"), e.g. fn=/dev/qcam. The width, height and bpp of the framebuffer can be set via, e.g., w=160,h=120,bpp=16. Related to the bpp above, the pixel format can be set via the fmt=XXX, where XXX can be one of: GREY, HI240, RGB555, RGB565, RGB24, and RGB32 (with bpp 8, 8, 16, 16, 24, and 32 respectively.) See http://www.linuxtv.org for more info (V4L api.) For TV/rf tuner cards one can set the tuning mode via tun=XXX where XXX can be one of PAL, NTSC, SECAM, or AUTO. One can switch the input channel by the inp=XXX setting, where XXX is the name of the input channel (Television, Composite1, S-Video, etc.) Use the name that is in the information about the device that is printed at startup. For input channels with tuners (e.g. Television) one can change which station is selected by the sta=XXX setting. XXX is the station number. Currently only the ntsc-cable-us (US cable) channels are built into x11vnc. See the -freqtab option below to supply one from xawtv. If XXX is greater than 500, then it is interpreted as a raw frequency in KHz. Example: -rawfb video:br=80,w=320,h=240,fmt=RGB32,tun=NTSC,sta=47 one might need to add inp=Television too for the input channel to be TV if the card doesn't come up by default in that one. Note that not all video capture devices will support all of the above settings. See the -pipeinput VID option below for a way to control the settings through the VNC Viewer via keystrokes. As above, if you specify a "@WxHxB..." after the string they are used verbatim: the device is not queried for the current values. Otherwise the device will be queried. ``` Also, if you supply the "-pipeinput VID" (or use "-rawfb Video") option you can control the settings to some degree via keystroke mappings, e.g. B to increase the brightness or Up arrow to change the TV station: ``` For "-pipeinput VID" and you are using the -rawfb for a video capture device, then an internal list of keyboard mappings is used to set parameters of the video. The mappings are: "B" and "b" adjust the brightness up and down. "H" and "h" adjust the hue. "C" and "c" adjust the colour. "N" and "n" adjust the contrast. "S" and "s" adjust the size of the capture screen. "I" and "i" cycle through input channels. Up and Down arrows adjust the station (if a tuner) F1, F2, ..., F6 will switch the video capture pixel format to HI240, RGB565, RGB24, RGB32, RGB555, and GREY respectively. See -rawfb video for details. ``` See also the -freqtab option to supply your own xawtv channel to frequency mappings for your country (only ntsc-cable-us is built into x11vnc.) ### Q-115: Can I connect via VNC to a Qt-embedded/Qt-enhanced/Qtopia application running on my handheld, cell phone, or PC using the Linux console framebuffer (i.e. not X11)? Yes, the basic method for this is the -rawfb scheme where the Linux console framebuffer (usually /dev/fb0) is polled and the uinput driver is used to inject keystrokes and mouse input. Often you will just have to type: ``` x11vnc -rawfb console ``` (you may need to enable the uinput driver on the system via "modprobe uinput; mknod /dev/input/uinput c 10 223") If this does not find the correct frame buffer properties figure them out or guess them and use something like: ``` x11vnc -rawfb /dev/fb0@640x480x16 ``` Also, to force usage of the uinput injection method use "-pipeinput UINPUT". See the -pipeinput description for tunable parameters, etc. One problem with the x11vnc uinput scheme is that it cannot guess the mouse motion "acceleration" used by the windowing application (e.g. QWS or X11.) For X11 and Qt-embedded the acceleration is usually 2 (i.e. a dx of 1 from the mouse yields a 2 pixel displacement of the mouse cursor.) The default x11vnc uses is 2, since that is often used. However for one Qt-embedded system we needed to do: ``` x11vnc -rawfb console -pipeinput UINPUT:accel=4.0 ``` to get reasonable positioning of the mouse. Even with the correct acceleration setting there is still some drift (probably because of the mouse threshold where the acceleration kicks in) and so x11vnc needs to reposition the cursor from 0,0 about 5 times a second. See the -pipeinput UINPUT option for tuning parameters that can be set (there are some experimental thresh=N tuning parameters as well) Currently, one can expect mouse input to be a little flakey. All in all, the Linux framebuffer input mechanism for Qt-embedded framebuffer apps is not perfect, but it is usable. If you need to create a smaller x11vnc binary for a handheld environment be sure to run strip(1) on it and also consider configuring with, e.g. "env CPPFLAGS='-DSMALL_FOOTPRINT=1' ./configure ..." to remove rarely used features and large texts (use 2 or 3 instead of 1 to remove more.) Currently (Jul/2006) this can lower the size of the x11vnc from 1.1MB to 0.6-0.7MB. The x11vnc uinput method applies to nearly anything on the Linux framebuffer console, not just Qt-embedded/Qtopia. DirectFB, SDL using fbcon driver, SVGAlib applications can also be viewed and interacted with. Even a Linux X session can be viewed and interacted with without using X11 (and x11vnc does not have to terminate when the X server restarts!) The Linux Text consoles (F1-F6) also work. Note that Qt-embedded supplies its own VNC graphics driver, but it cannot do both the Linux console framebuffer and VNC at the same time, which is often what is desired from VNC. Update: We are finding some setups like Qtopia on the IPAQ do not allow mouse input via uinput. Please help us debug this problem by trying x11vnc on your device and letting us know what does and does not work. See the next FAQ for a possible workaround for touchscreens. ### Q-116: How do I inject touch screen input into an Qt-embedded/Qt-enhanced/Qtopia cell phone such as openmoko/qtmoko Neo Freerunner? The qtmoko project does not use X11 for the graphical display. Unfortunately the Linux uinput method described in the previous FAQ does not work because Qt is using TSLIB (touch screen library) to process the input and it only reads from one device (often /dev/input/event1) and not from the new UINPUT device that x11vnc creates (under -pipeinput UINPUT) So something else needs to be done. It was discovered that by simply writing the touchscreen events directly to /dev/input/event1 then input can be injected into the system. There is no x11vnc builtin mode for this yet (until we understand it better), but there is a working script provided in x11vnc/misc/qt_tslib_inject.pl. So one could use it this way for example: ``` x11vnc ... -rawfb console -pipeinput path/to/qt_tslib_inject.pl -env INJECT_OPTIONS=clickonly,cal=/etc/pointercal ``` Read the script for how to enable other options and what the above options mean (e.g. /etc/pointercal contains TSLIB's calibration parameters and are necessary to achieve accurate pointing.) The x11vnc/misc/qt_tslib_inject.pl script can potentially be modified to handle other devices where the uinput method fails. It could also be modified to create 'hot keys', etc. Please let us know how things go if you try this out; there is much to learn about synthetic input injection in handhelds and cell phones. As we learn more we can develop a builtin x11vnc mode for this sort of injection. Update Dec/2010: There is experimental built-in UINPUT support in the x11vnc development tarball for qtmoko with touchpad managed by tslib. See -pipeinput UINPUT for more info. Here is an example: ``` x11vnc -rawfb console -pipeinput UINPUT:touch,tslib_cal=/etc/pointercal,direct_abs=/dev/input/event1,nouinput,dragskip=3 ``` ### Q-117: Now that non-X11 devices can be exported via VNC using x11vnc, can I build it with no dependencies on X11 header files and libraries? Yes, as of Jul/2006 x11vnc enables building for -rawfb only support. Just do something like when building: ``` ./configure --without-x (plus any other flags) make ``` You can then test via "ldd x11vnc" that the binary does not depend on libX11.so, etc. See the previous FAQ's for non-X11 framebuffer usage. If you use this for an interesting non-X11 application please let us know what you did. ### Q-118: How do I cross compile x11vnc for a different architecture than my Linux i386 or amd64 PC? You will need a cross-compiling toolchain. Perhaps your distro provides these or you can find a HOWTO for your distro. We found a nice one at qtmoko.org for building armel binaries on Debian Linux i386 machines. It includes most of the libraries that x11vnc needs. We use that example here. We ran this script to set PATH, configure, and build: ``` #!/bin/sh # toolchain from: qtmoko-debian-toolchain-armv4t-eabi.tar.gz export PATH=/opt/toolchains/arm920t-eabi/bin:$PATH env CC=arm-linux-gcc ./configure --host=arm-linux --without-avahi make arm-linux-strip ./x11vnc/x11vnc ls -l ./x11vnc/x11vnc ``` Note we had to include --without-avahi due to lack of libavahi-client.so.3 supplied by the toolchain we used. One would need to add it if it was desired on the target machine. We also stripped the binary to make it smaller. For an embedded system one may also want to add --without-x if the embedded system does not use X11 and the -rawfb mechanism must be used. ### Q-119: Does x11vnc support Mac OS X Aqua/Quartz displays natively (i.e. no X11 involved)? Yes, since Nov/2006 in the development tree (x11vnc-0.8.4 tarball) there is support for native Mac OS X Aqua/Quartz displays using the -rawfb mechanism described above. The mouse and keyboard input is achieved via Mac OS X API's. So you can use x11vnc as an alternative to OSXvnc (aka Vine Server), or Apple Remote Desktop (ARD). Perhaps there is some x11vnc feature you'd like to use on Mac OS X, etc. For a number of activities (e.g. window drags) it seems to be faster than OSXvnc. Notes: X11: x11vnc will also work (as it has for years) with a X11 server (XDarwin) running on Mac OS X (people often install this software to display remote X11 apps on their Mac OS X system, or use some old favorites locally such as xterm.) However in this case x11vnc will only work reasonably in single window -id windowid mode (and the window may need to have mouse focus.) If you do not have the DISPLAY env. variable set, x11vnc will assume native Aqua/Quartz on Mac OS X, however if DISPLAY is set it will assume an X11 connection. Use "-rawfb console" to force the native display (or unset DISPLAY.) Update: Leopard sets DISPLAY by default in all sessions. Since it starts with the string "/tmp/" x11vnc will use that to know if it should ignore it. Use "-display :0.0" to force it. Building: If you don't have the X11 build and runtime packages installed you will need to build it like this: (cd to the e.g. x11vnc-0.9, source directory) ``` ./configure --without-x make ``` Win2VNC/x2vnc: One handy use is to use the -nofb mode to redirect mouse and keyboard input to a nearby Mac (i.e. one to the side of your desk) via x2vnc or Win2VNC. See this FAQ for more info. Options: Here are the Mac OS X specific x11vnc options: ``` -macnodim For the native Mac OS X server, disable dimming. -macnosleep For the native Mac OS X server, disable display sleep. -macnosaver For the native Mac OS X server, disable screensaver. -macnowait For the native Mac OS X server, do not wait for the user to switch back to his display. -macwheel n For the native Mac OS X server, set the mouse wheel speed to n (default 5.) -macnoswap For the native Mac OS X server, do not swap mouse buttons 2 and 3. -macnoresize For the native Mac OS X server, do not resize or reset the framebuffer even if it is detected that the screen resolution or depth has changed. -maciconanim n For the native Mac OS X server, set n to the number of milliseconds that the window iconify/deiconify animation takes. In -ncache mode this value will be used to skip the animation if possible. (default 400) -macmenu For the native Mac OS X server, in -ncache client-side caching mode, try to cache pull down menus (not perfect because they have animated fades, etc.) ``` PasteBoard/Clipboard: There is a bug that the Clipboard (called PasteBoard on Mac it appears) exchange will not take place unless x11vnc was started from inside the Aqua display (e.g. started inside a Terminal app window.) Otherwise it cannot connect to the PasteBoard server. So Clipboard exchange won't work for our standard "ssh in" startup scheme. Hopefully this deficiency can be removed, but until then for Clipboard exchange to work you will need to start x11vnc inside the desktop session (i.e. either start it running before you leave, or start up a 2nd x11vnc inside from a 1st one started outside, or use the apple script below) Here also is a osascript trick that seems to work (it opens the Terminal app and instructs it to start x11vnc): ``` #!/bin/sh # # start_x11vnc: start x11vnc in a Terminal window # (this will allow Clipboard/Pasteboard exchange to work) tmp=/tmp/start_x11vnc.$$ cat > $tmp < vncviewer -listen client2> vncviewer -listen client3> vncviewer -listen ... client64> vncviewer -listen ``` (e.g. client1> is the cmdline prompt on machine client1 ... etc) and all the repeaters R are started like this: ``` repeater1> x11vnc -reflect listen -connect client1,client2,...client8 repeater2> x11vnc -reflect listen -connect client9,client10,...client16 ... repeater8> x11vnc -reflect listen -connect client57,client58,...client64 ``` and finally the main server is started to kick the whole thing into motion: ``` vncserver> x11vnc -display :0 -connect repeater1,repeater2,...repeater8 ``` (or instruct a non-x11vnc VNC server to reverse connect to the repeaters.) For a classroom broadcasting setup one might have the first two sets of commands start automatically at bootup or when someone logs in, and then start everything up with the S server. One may even be able to script the forward connection bootstrap case, let us know what you did. A really nice thing would be some sort of auto-discovery of your repeater, etc... ### Q-121: Can x11vnc be used during a Linux, Solaris, etc. system installation so the installation can be done remotely? This can be done, but it doesn't always work because it depends on how the OS does its install. We have to "sneak in" somehow. Note that some OS's have a remote install (ssh etc.) built in and so you might want to use that instead. Usually the OS install will have to be a network-install in order to have networking up during the install. Otherwise, you may have a (slim) chance to configure the networking manually (ifconfig(8) and route(8).) To avoid library dependencies problems in the typical minimal (e.g. busybox) installation OS it is a good idea to build a statically linked x11vnc binary. A way that often works is to do a normal build and then paste the final x11vnc link line into a shell script. Then change the "gcc" to "gcc -static" and run the shell script. You may need to disable features (e.g. "--without-xfixes") if there is not a static library for the feature available. You may also need to add extra link options (e.g. "-lXrender") to complete library dependencies manually. Let's call the binary x11vnc.static. Place it on a webserver somewhere. It may be possible to retrieve it via scp(1) too. During the install you need to get a shell to retreive x11vnc.static and run it. If the Solaris install is an older X-based one, there will be a menu for you to get a terminal window. From that window you might be able to retrieve x11vnc.static via wget, scp, or ftp. Remember to do "chmod 755 ./x11vnc.static" and then find the -auth file as in this FAQ. If it is a Linux install that uses an X server (e.g. SuSE and probably Fedora), then you can often get a shell by pressing Ctrl-Alt-F2 or similar. Then get the x11vnc binary via something like this: ``` cd /tmp wget http://192.168.0.22/x11vnc.static chmod 755 ./x11vnc.static ``` Find the name of the auth file as in this FAQ. (maybe run "ps wwaux | grep auth".) Then run it like this: ./x11vnc.static -forever -nopw -display :0 -auth /tmp/wherever/the/authfile then press Alt-F7 to go back to the X install. You should now be able to connect via a vnc viewer and continue the install. Watch out for the display being :1, etc. If there is a firewall blocking incoming connections during the install, use the "-connect hostname" option option for a reverse connection to the hostname running the VNC viewer in listen mode. Debian based installs are either console-text or console-framebuffer based. These are install (or expert) and installgui (or expertgui) boot lines, respectively. For the console-text based installs you probably need to add a boot cmd line option like vga=0x314 (which is 800x600x16) to get the console-text to use the linux framebuffer device properly. For a Debian console-text based install after the network is configured press Ctrl-Alt-F2 to get a shell. Retrieve the binary via wget as above and chmod 755 it. Then run it something like this: sleep 10; ./x11vnc.static -forever -nopw -rawfb console then before the sleep is over press Alt-F1 to get back to the install virtual console. You should be able to connect via a VNC viewer and continue with the install. For a recent (2009) Debian install we booted with "expert vga=0x301" and "expert vga=0x311" to get console text based installs at 640x480x8 and 640x480x16, respectively (replace "expert" with "install" if you like.) Otherwise it was giving a 16 color 640x480x4 (4 bit per pixel) display which x11vnc could not handle. For Debian console-framebuffer GUI based installs (installgui or expertgui) we have not be able to enter keystrokes or mouse motions. This may be resolved if the install had the Linux kernel module uinput, but it doesn't; one can wget uinput.ko and then run insmod on it, but the module must match the installation kernel. So, failing that, you can only do the GUI view-only, which can be handy to watch a long network install from your desk instead of in front of the machine being installed. For these, after the network is configured press Ctrl-Alt-F2 to get a shell. Retrieve the binary via wget as above and chmod 755 it. Then run it something like this: sleep 10; ./x11vnc.static -forever -nopw -rawfb console then before the sleep is over press Alt-F5 to get back to the GUI install console. You should be able to connect via a VNC viewer and watch the install. [Misc: Clipboard, File Transfer/Sharing, Printing, Sound, Beeps, Thanks, etc.] ### Q-122: Does the Clipboard/Selection get transferred between the vncviewer and the X display? As of Jan/2004 x11vnc supports the "CutText" part of the RFB (aka VNC) protocol. When text is selected/copied in the X session that x11vnc is polling it will be sent to connected VNC viewers. And when CutText is received from a VNC viewer then x11vnc will set the X11 selections PRIMARY, CLIPBOARD, and CUTBUFFER0 to it. x11vnc is able to hold the PRIMARY and CLIPBOARD selections (Xvnc does not seem to do this.) The X11 selections can be confusing, especially to those coming from Windows or MacOSX where there is just a single 'Clipboard'. The X11 CLIPBOARD selection is a lot like that of Windows and MacOSX, e.g. highlighted text is sent to the clipboard when the user activates "Edit -> Copy" or presses "Control+C" (and pasting it via "Edit -> Paste" or "Control+V".) The X11 PRIMARY selection has been described as 'for power users' or 'an Easter Egg'. As soon as text is highlighted it is set to the PRIMARY selection and so it is immediately ready for pasting, usually via the Middle Mouse Button or "Shift+Insert". See this jwz link for more information. x11vnc's default behavior is to watch both CLIPBOARD and PRIMARY and whenever one of them changes, it sends the new text to connected viewers. Note that since the RFB protocol only has a single "CutText" then both selections are "merged" to some degree (and this can lead to confusing results.) One user was confused why x11vnc was "forgetting" his CLIPBOARD selection and the reason was he also changed PRIMARY some time after he copied text to the clipboard. Usually an app will set PRIMARY as soon as any text is highlighted so it easy to see how CLIPBOARD was forgotten. Use the -noprimary described below as a workaround. Similarly, by default when x11vnc receives CutText it sets both CLIPBOARD and PRIMARY to it (this is probably less confusing, but could possibly lead to some failure modes as well.) You may not like these defaults. Here are ways to change the behavior: * If you don't want the Clipboard/Selection exchanged at all use the -nosel option. * If you want changes in PRIMARY to be ignored use the -noprimary option. * If you want changes in CLIPBOARD to be ignored use the -noclipboard option. * If you don't want x11vnc to set PRIMARY to the "CutText" received from viewers use the -nosetprimary option. * If you don't want x11vnc to set CLIPBOARD to the "CutText" received from viewers use the -nosetclipboard option. You can also fine-tune it a bit with the -seldir dir option and also -input. You may need to watch out for desktop utilities such as KDE's "Klipper" that do odd things with the selection, clipboard, and cutbuffers. ### Q-123: Can I use x11vnc to record a Shock Wave Flash (or other format) video of my desktop, e.g. to record a tutorial or demo? Yes, it is possible with a number of tools that record VNC and transform it to swf format or others. One such popular tool is pyvnc2swf. There are a number of tutorials (broken link?) on how to do this. Another option is to use the vnc2mpg that comes in the LibVNCServer package. An important thing to remember when doing this is that tuning parameters should be applied to x11vnc to speed up its polling for this sort of application, e.g. "-wait 10 -defer 10". ### Q-124: Can I transfer files back and forth with x11vnc? As of Oct/2005 and May/2006 x11vnc enables, respectively, the TightVNC and UltraVNC file transfer implementations that were added to libvncserver. This currently works with TightVNC and UltraVNC viewers (and Windows viewers only support filetransfer it appears... but they do work to some degree under Wine on Linux.) The SSVNC Unix VNC viewer supports UltraVNC file transfer by use of a Java helper program. TightVNC file transfer is off by default, if you want to enable it use the -tightfilexfer option. UltraVNC file transfer is off by default, to enable it use something like "-rfbversion 3.6 -permitfiletransfer" options (UltraVNC incorrectly uses the RFB protocol version to determine if its features are available, so x11vnc has to pretend to be version 3.6.) As of Sep/2006 "-ultrafilexfer" is an alias for these two options. Note that running as RFB version 3.6 may confuse other VNC Viewers. Sadly you cannot do both -tightfilexfer and -ultrafilexfer at the same time because the latter requires setting the version to 3.6 and tightvnc will not do filetransfer when it sees that version number. Also, because of the way the LibVNCServer TightVNC file transfer is implemented, you cannot do Tightvnc file transfer in -unixpw mode. However, UltraVNC file transfer does work in -unixpw (but if a client tries it do a filetransfer during the login process it will be disconnected.) IMPORTANT: please understand if -ultrafilexfer or -tightfilexfer is specified and you run x11vnc as root for, say, inetd or display manager (gdm, kdm, ...) access and you do not have it switch users via the -users option, then VNC Viewers that connect are able to do filetransfer reads and writes as *root*. The UltraVNC and TightVNC settings can be toggled on and off inside the gui or by -R remote control. However for TightVNC the changed setting only applies for NEW clients, current clients retain their TightVNC file transfer ability. For UltraVNC it works better, however if an UltraVNC client has initiated a file transfer dialog it will remain in effect until the dialog is closed. If you want to switch between UltraVNC and TightVNC file transfer in the gui or by remote control you will probably be foiled by the "-rfbversion 3.6" issue. ### Q-125: Which UltraVNC extensions are supported? Some of them are supported. To get UltraVNC Viewers to attempt to use these extensions you will need to supply this option to x11vnc: -rfbversion 3.6 Or use -ultrafilexfer which is an alias for the above option and "-permitfiletransfer". UltraVNC evidently treats any other RFB version number as non-UltraVNC. Here are a list of the UltraVNC extensions supported by x11vnc: * ServerInput: "Toggle Remote Input and Remote Blank Monitor" * FileTransfer: "Open File Transfer..." * SingleWindow: "Select Single Window..." * TextChat: "Open Chat..." * 1/n Server Scaling The SSVNC Unix VNC viewer supports these UltraVNC extensions. To disable SingleWindow and ServerInput use -noultraext (the others are managed by LibVNCServer.) See this option too: -noserverdpms. Also, the UltraVNC repeater proxy is supported for use with reverse connections: "-connect repeater://host:port+ID:NNNN". Use it for both plaintext and SSL connections. This mode can send any string before switching to the VNC protocol, and so could be used with other proxy/gateway tools. Also, a perl repeater implemention is here: ultravnc_repeater.pl ### Q-126: Can x11vnc emulate UltraVNC's Single Click helpdesk mode for Unix? I.e. something very simple for a naive user to initiate a reverse vnc connection from their Unix desktop to a helpdesk operator's VNC Viewer. Yes, UltraVNC's Single Click (SC) mode can be emulated fairly well on Unix. We use the term "helpdesk" below, but it could be any sort of remote assistance you want to set up, e.g. something for Unix-using friends or family to use. This includes Mac OS X. Assume you create a helpdesk directory "hd" on your website: http://www.mysite.com/hd (any website that you can upload files to should work, although remember the user will be running the programs you place there.) In that "hd" subdirectory copy an x11vnc binary to be run on the Unix user's machine (e.g. Linux, etc) and also create a file named "vnc" containing the following: ``` #!/bin/sh webhost="http://www.mysite.com/hd" # Your helpdesk dir URL. vnchost="ip.someplace.net" # Your host running 'vncviewer -listen' # It could also be your IP number. If it is # a router/firewall, you will need to # configure it to redirect port 5500 to your # workstation running 'vncviewer -listen' dir=/tmp/vnc_helpdesk.$$ # Make a temporary working dir. mkdir $dir || exit 1 cd $dir || exit 1 trap "cd /tmp; rm -rf $dir" 0 2 15 # Cleans up on exit. wget $webhost/x11vnc # Fetch x11vnc binary. If multi- chmod 755 ./x11vnc # platform, use $webhost/`uname`/x11vnc # or similar. ./x11vnc -connect_or_exit $vnchost -rfbport 0 -nopw ``` with the hostnames / IP addresses customized to your case. On the helpdesk VNC viewer machine (ip.someplace.net in this example) you have the helpdesk operator running VNC viewer in listen mode: vncviewer -listen or if on Windows, etc. somehow have the VNC viewer be in "listen" mode. Then, when the naive user needs assistance you instruct him to open up a terminal window on his Unix desktop and paste the following into the shell: ``` wget -qO - http://www.mysite.com/hd/vnc | sh - ``` and then press Enter. You could have this instruction on a web page or in an email you send him, etc. This requires that the wget is installed on the user's Unix machine (he might only have curl or lynx, see below for more info.) So I guess this is about 3-4 clicks (start a terminal and paste) and pressing "Enter" instead of "single click"... See this page for some variations on this method, e.g. how to add a password, SSL Certificates, etc. If you don't have a website (there are many free ones) or don't want to use one you will have to email him all of the ingredients (x11vnc binary and a launcher script) and tell him how to run it. This could be easy or challenging depending on the skill of the naive unix user... A bit of obscurity security could be put in with a -passwd, -rfbauth options, etc. (note that x11vnc will require a password even for reverse connections.) More info here. Firewalls: If the helpdesk (you) with the vncviewer is behind a NAT/Firewall/Router the router will have to be configured to redirect a port (i.e. 5500 or maybe different one if you like) to the vncviewer machine. If the vncviewer machine also has its own host-level firewall, you will have to open up the port there as well. NAT-2-NAT: There is currently no way to go "NAT-2-NAT", i.e. both User and Helpdesk workstations behind NAT'ing Firewall/Routers without configuring a router to do a port redirection (i.e. on your side, the HelpDesk.) To avoid modifying either firewall/router, one would need some public (IP address reachable on the internet) redirection/proxy service. Perhaps such a thing exists. http://sc.uvnc.com provides this service for their UltraVNC Single Click users. Update: It may be possible to do "NAT-2-NAT" with a UDP tunnel such as http://samy.pl/pwnat/. All that is required is that both NAT firewalls allow in UDP packets from an IP address to which a UDP packet has recently been sent to. If you try it out let us know how it went. Very Naive Users: If it is beyond the user how to open a terminal window and paste in a command (you have my condolences...) you would have to somehow setup his Web browser to download the "vnc" file (or a script containing the above wget line) and prompt the user if he wants to run it. This may be tricky to set up (which is probably a good thing to not have the web browser readily run arbitrary programs downloaded from the internet...) One command-line free way, tested with KDE, is to name the file vnc.sh and then instruct the user to right-click on the link and do "Save Link As" to his Desktop. It will appear as an icon, probably one that looks like a terminal or a command line prompt. He next should right-click on the icon and select "Properties" and go to the "Permissions" tab. Then in that dialog select the checkbox "Is executable". He should then be able to click on the icon to launch it. Another option is to right-click on the icon and select "Open With -> Other ..." and for the name of the application type in "/bin/sh". Unfortunately in both cases the command output is lost and so errors cannot be debugged as easily. A similar thing appears to work in GNOME if under "Properties -> Permissions" they click on "Execute" checkbox for "Owner". Then when they click on the icon, they will get a dialog where they can select "Run in Terminal". In general for such cases, if it is feasible, it might be easier to ssh to his machine and set things up yourself... SSL Encrypted Helpdesk Connections: As of Apr/2007 x11vnc supports reverse connections in SSL and so we can do this. On the Helpdesk side (Viewer) you will need STUNNEL or better use the Enhanced TightVNC Viewer (SSVNC) package we provide that automates all of the SSL for you. To do this create a file named "vncs" in the website "hd" directory containing the following: ``` #!/bin/sh webhost="http://www.mysite.com/hd" # Your helpdesk dir URL. vnchost="ip.someplace.net" # Your host running 'vncviewer -listen' # It could also be your IP number. If it is # a router/firewall, you will need to # configure it to redirect port 5500 to your # workstation running 'vncviewer -listen' dir=/tmp/vnc_helpdesk.$$ # Make a temporary working dir. mkdir $dir || exit 1 cd $dir || exit 1 trap "cd /tmp; rm -rf $dir" 0 2 15 # Cleans up on exit. wget $webhost/x11vnc # Fetch x11vnc binary. If multi- chmod 755 ./x11vnc # platform, use $webhost/`uname`/x11vnc # or similar. ./x11vnc -connect_or_exit $vnchost -rfbport 0 -nopw -ssl # Note -ssl option. ``` with the hostnames or IP addresses customized to your case. The only change from the "vnc" above is the addition of the -ssl option to x11vnc. This will create a temporary SSL cert: openssl(1) will need to be installed on the user's end. A fixed SSL cert file could be used to avoid this (and provide some authentication; more info here.) The naive user will be doing this: ``` wget -qO - http://www.mysite.com/hd/vncs | sh - ``` (or perhaps even use https:// if available.) But before that, the helpdesk operator needs to have "vncviewer -listen" running as before, however he needs an SSL tunnel at his end. The easiest way to do this is use Enhanced TightVNC Viewer (SSVNC). Start it, and select Options -> 'Reverse VNC Connection (-listen)'. Then UN-select 'Verify All Certs' (this can be enabled later if you want; you'll need the x11vnc SSL certificate), and click 'Listen'. If you don't want to use SSVNC for the viewer, but rather set up STUNNEL manually instead, make a file "stunnel.cfg" containing: ``` foreground = yes pid = [vnc] accept = 5500 connect = localhost:5501 ``` and run: ``` stunnel ./stunnel.cfg ``` and then start the "vncviewer -listen 1" (i.e. 1 to correspond to the 5501 port.) Note that this assumes the stunnel install created a Server SSL cert+key, usually /etc/stunnel/stunnel.pem (not all distros will do this.) Also, that file is by default only readable by root, so stunnel needs to be run as root. If your system does not have a key installed or you do not want to run stunnel as root (or change the permissions on the file), you can use x11vnc to create one for you for example: ``` x11vnc -sslGenCert server self:mystunnel ``` answer the prompts with whatever you want; you can take the default for all of them if you like. The openssl(1) package must be installed. See this link and this one too for more info on SSL certs. This creates $HOME/.vnc/certs/server-self:mystunnel.pem, then you would change the "stunnel.cfg" to look something like: ``` foreground = yes pid = cert = /home/myusername/.vnc/certs/server-self:mystunnel.pem [vnc] accept = 5500 connect = localhost:5501 ``` In any event, with stunnel having been setup, the naive user is instructed to paste in and run: wget -qO - http://www.mysite.com/hd/vncs | sh - to pick up the vncs script this time. Of course if a man-in-the-middle can alter what the user downloads then all bets are off!. More SSL variations and info about certificates can be found here. OpenSSL libssl.so.0.9.7 problems: If you build your own stunnel or x11vnc for deployment, you may want to statically link libssl.a and libcrypto.a into it because Linux distros are currently a bit of a mess regarding which version of libssl is installed. You will find the details here. ### Q-127: Can I (temporarily) mount my local (viewer-side) Windows/Samba File share on the machine where x11vnc is running? You will have to use an external network redirection for this. Filesystem mounting is not part of the VNC protocol. We show a simple Samba example here. First you will need a tunnel to redirect the SMB requests from the remote machine to the one you sitting at. We use an ssh tunnel: sitting-here> ssh -C -R 1139:localhost:139 far-away.east Or one could combine this with the VNC tunnel at the same time, e.g.: ``` sitting-here> ssh -C -R 1139:localhost:139 -t -L 5900:localhost:5900 far-away.east 'x11vnc -localhost -display :0' ``` Port 139 is the Windows Service port. For Windows systems instead of Samba, you may need to use the actual IP address of the Window machine instead of "localhost" in the -R option (since the Windows service does not listen on localhost by default.) Note that we use 1139 instead of 139 on the remote side because 139 would require root permission to listen on (and you may have a samba server running on it already.) The ssh -C is to enable compression, which might speed up the data transfers. Depending on the remote system side configuration, it may or may not be possible to mount the SMB share as a non-root user. Try it first as a non-root user and if that fails you will have to become root. We will assume the user name is "fred" and we will try to mount the viewer-side Windows SMB share "//haystack/pub" in /home/fred/smb-haystack-pub. ``` far-away> mkdir -p /home/fred/smb-haystack-pub far-away> smbmount //haystack/pub /home/fred/smb-haystack-pub -o username=fred,ip=127.0.0.1,port=1139 ``` (The 2nd command may need to be run as root.) Then run "df" or "ls -l /home/fred/smb-haystack-pub" to see if it is mounted properly. Consult the smbmount(8) and related documentation (it may require some fiddling to get write permissions correct, etc.) To unmount: ``` far-away> smbumount /home/fred/smb-haystack-pub ``` At some point we hope to fold some automation for SMB ssh redir setup into the Enhanced TightVNC Viewer (SSVNC) package we provide (as of Sep 2006 it is there for testing.) ### Q-128: Can I redirect CUPS print jobs from the remote desktop where x11vnc is running to a printer on my local (viewer-side) machine? You will have to use an external network redirection for this. Printing is not part of the VNC protocol. We show a simple Unix to Unix CUPS example here. Non-CUPS port redirections (e.g. LPD) should also be possible, but may be a bit more tricky. If you are viewing on Windows SMB and don't have a local cups server it may be trickier still (see below.) First you will need a tunnel to redirect the print requests from the remote machine to the one you sitting at. We use an ssh tunnel: sitting-here> ssh -C -R 6631:localhost:631 far-away.east Or one could combine this with the VNC tunnel at the same time, e.g.: ``` sitting-here> ssh -C -R 6631:localhost:631 -t -L 5900:localhost:5900 far-away.east 'x11vnc -localhost -display :0' ``` Port 631 is the default CUPS port. The above assumes you have a Cups server running on your viewer machine (localhost:631), if not, use something like my-cups-srv:631 (the viewer-side Cups server) in the -R instead. Note that we use 6631 instead of 631 on the remote side because 631 would require root permission to listen on (and you likely have a cups server running on it already.) Now the tricky part: to get applications to notice your cups server/printer on localhost:6631. If you have administrative privilege (i.e. root password) on the x11vnc side where the desktop is running, it should be easy to add the printer through some configuration utility (e.g. in KDE: Utilities -> Printing -> Printing Manager, and then supply admin password, and then Add Printer/Class, and then fill in the inquisitive wizard. Most important is the "Remote IPP server" panel where you put in localhost for Host and 6631 for Port.) The main setting you want to convey is the host is localhost and the port is non-standard (e.g. 6631.) Some configuration utilities will take an Internet Printing Protocol (IPP) URI, e.g. http://localhost:6631/printers/, ipp://localhost:6631/printers/printer-name, ipp://localhost:6631/ipp/printer-name, etc. Check your CUPS documentation and admin interfaces to find what the syntax is and what the "printer name" is. If you do not have root or print admin privileges, but are running a recent (version 1.2 or greater) of the Cups client software, then an easy way to temporarily switch Cups servers is to create the directory and file: $HOME/.cups/client.conf on the remote side with a line like: ``` ServerName localhost:6631 ``` When not using x11vnc for remote access you can comment the above line out with a '#' (or rename the client.conf file), to have normal cups operation. Unfortunately, running applications may need to be restarted to notice the new printers (libcups does not track changes in client.conf.) Depending on circumstances, a running application may actually notice the new printers without restarting (e.g. no print dialog has taken place yet, or there are no CUPS printers configured on the remote side.) Cups client software that is older (1.1) does not support appending the port number, and for newer ones there is a bug preventing it from always working (fixed in 1.2.3.) Kludges like these at the command line will work: ``` far-away> env CUPS_SERVER=localhost IPP_PORT=6631 lpstat -p -d far-away> env CUPS_SERVER=localhost IPP_PORT=6631 lpr -P myprinter file.ps far-away> env CUPS_SERVER=localhost IPP_PORT=6631 firefox ``` but are somewhat awkward since you have to retroactively set the env. var IPP_PORT. Its value cannot be broadcast to already running apps (like the $HOME/.cups/client.conf trick sometimes does.) A common workaround for an already running app is to somehow get it to "Print To File", e.g. file.ps and then use something like the lpr example above. Also, the option "-h host:port" works with CUPS lp(1) and lpr(1). You can also print to Windows shares printers in principle. You may do this with the smbspool(8) command, or configure the remote CUPS via lpadmin(8), etc, to use a printer URI something like smb://machine:port/printer (this may have some name resolution problems WRT localhost.) Also, as with SMB mounting, the port redir (-R) to the Windows machine must use the actual IP address instead of "localhost". At some point we hope to fold some automation for CUPS ssh redir setup into the Enhanced TightVNC Viewer (SSVNC) package we provide (as of Sep 2006 it is there for testing.) ### Q-129: How can I hear the sound (audio) from the remote applications on the desktop I am viewing via x11vnc? You will have to use an external network audio mechanism for this. Audio is not part of the VNC protocol. We show a simple Unix to Unix esd example here (artsd should be possible too, we have also verified the esd Windows port works for the method described below.) First you will need a tunnel to redirect the audio from the remote machine to the one you sitting at. We use an ssh tunnel: sitting-here> ssh -C -R 16001:localhost:16001 far-away.east Or one could combine this with the VNC tunnel at the same time, e.g.: ``` sitting-here> ssh -C -R 16001:localhost:16001 -t -L 5900:localhost:5900 far-away.east 'x11vnc -localhost -display :0' ``` Port 16001 is the default ESD uses. So when an application on the remote desktop makes a sound it will connect to this tunnel and be redirected to port 16001 on the local machine (sitting-here in this example.) The -C option is an attempt to compress the audio a little bit. So we next need a local (sitting-here) esd daemon running that will receive those requests and play them on the local sound device: ``` sitting-here> esd -promiscuous -port 16001 -tcp -bind 127.0.0.1 ``` See the esd(1) man page for the meaning of the options (the above are not very secure.) (This method also works with the EsounD windows port esd.exe) To test this sound tunnel, we use the esdplay program to play a simple .wav file: ``` far-away> esdplay -s localhost:16001 im_so_happy.wav ``` If you hear the sound (Captain Kirk in this example), that means you are in great shape. To run individual audio applications you can use the esddsp(1) command: ``` far-away> esddsp -s localhost:16001 xmms ``` Then you could try playing some sounds inside xmms. You could also set the environment variable ESPEAKER=localhost:16001 to not need to supply the -s option all the time. (for reasons not clear, sometimes esddsp can figure it out on its own.) All the script esddsp does is to set ESPEAKER and LD_PRELOAD for you so that when the application opens the sound device (usually /dev/dsp) its interactions with the device will be intercepted and sent to the esd daemon running on sitting-here (that in turn writes them to the real, local /dev/dsp.) Redirecting All sound: It does not seem to be possible to switch all of the sound of the remote machine from its sound device to the above esd+ssh tunnel without some preparation. But it can be done reasonably well if you prepare (i.e. restart) the desktop with this in mind. Here is one way to redirect all sound. The idea is we run the entire desktop with sound directed to localhost:16001. When we are sitting at far-away.east we run "esd -promiscuous -port 16001 -tcp -bind 127.0.0.1" on far-away.east (to be able to hear the sound.) However, when we are sitting at sitting-here.west we kill that esd process and run that same esd command on sitting-here.west and start up the above ssh tunnel. This is a little awkward, but with some scripts one would probably kill and restart the esd processes automatically when x11vnc is used. So next we have to run the whole desktop pointing toward our esd. Here is a simple way to test. Log in to the machine via the "FailSafe" desktop. Then in the lone terminal type something like: ``` esddsp -s localhost:16001 gnome-session ``` or: ``` esddsp -s localhost:16001 startkde ``` where the last part is whatever command starts your desktop (even fvwm2.) This causes the environment variables ESPEAKER and LD_PRELOAD to be set appropriately and every application (processes with the desktop as an ancestor) will use them. If this scheme works well you can make it less klunky by adding the command to your ~/.xsession, etc. file that starts your default desktop. Or you may be able to configure your desktop to use localhost:16001, or whatever is needed, via a gui configuration panel. Some Notes: * Not all audio applications are compatible with the esd and artsd mechanisms, but many are. * The audio is not compressed so you probably need a broadband or faster connection. Listening to music may not be very pleasant... (Although we found streaming music from across the US over cable modem worked OK, but took 200 KB/sec, to use less bandwidth consider something like "ssh far-away.east 'cat favorite.mp3' | mpg123 -b 4000 -") * Linux does not seem to have the concept of LD_PRELOAD_64 so if you run on a mixed 64- and 32-bit ABI system (e.g. AMD x86_64) some of the applications will fail to run because LD_PRELOAD will point to libraries of the wrong wordsize. * At some point we hope to fold some automation for esd or artsd ssh redir setup into the Enhanced TightVNC Viewer (SSVNC) package we provide (as of Sep/2006 it is there for testing.) ### Q-130: Why don't I hear the "Beeps" in my X session (e.g. when typing tput bel in an xterm)? As of Dec/2003 "Beep" XBell events are tracked by default. The X server must support the XKEYBOARD extension (this is not on by default in Solaris, see Xserver(1) for how to turn it on via +kb), and so you won't hear them if the extension is not present. If you don't want to hear the beeps use the -nobell option. If you want to hear the audio from the remote applications, consider trying a redirector such as esd. ### Q-131: Does x11vnc work with IPv6? Update: as of Apr/2010 in the 0.9.10 x11vnc development tarball, there is now built-in support for IPv6 (128 bit internet addresses.) See the -6 and -connect options for details. The remainder of this FAQ entry shows how to do with this with pre 0.9.10 x11vnc using IPv6 helper tools. --- Using an external IPv6 helper: A way to do this is via a separate helper program such as inetd (or for encrypted connections: ssh or stunnel.) For example, you configure x11vnc to be run from inetd or xinetd and instruct it to listen on an IPv6 address. For xinetd the setting "flags = IPv6" will be needed. For inetd.conf, an example is: ``` 5900 stream tcp6 nowait root /usr/sbin/tcpd /usr/local/bin/x11vnc_wrapper.sh ``` We also provide a transitional tool in "x11vnc/misc/inet6to4" that acts as a relay for any IPv4 application to allow connections over IPv6. For example: ``` inet6to4 5900 localhost:5900 ``` where x11vnc is listening on IPv4 port 5900. Also note that not all VNC Viewers are IPv6 enabled, so a redirector may also be needed for them. The tool "inet6to4 -r ..." can do this as well. SSVNC (see below) supports IPv6 without need for the helper. ``` # ./inet6to4 -help inet6to4: Act as an ipv6-to-ipv4 relay for tcp applications that do not support ipv6. Usage: inet6to4 inet6to4 -r Examples: inet6to4 5900 localhost:5900 inet6to4 8080 web1:80 inet6to4 -r 5900 fe80::217:f2ff:fee6:6f5a%eth0:5900 The -r option reverses the direction of translation (e.g. for ipv4 clients that need to connect to ipv6 servers.) Reversing is the default if this script is named 'inet4to6' (e.g. by a symlink.) Use Ctrl-C to stop this program. You can also set env. vars INET6TO4_LOOP=1 or INET6TO4_LOOP=BG to have an outer loop restarting this program (BG means do that in the background), and INET6TO4_LOGFILE for a log file. Also set INET6TO4_VERBOSE to verbosity level and INET6TO4_WAITTIME and INET6TO4_PIDFILE (see below.) ``` The "INET6TO4_LOOP=BG" and "INET6TO4_LOGFILE=..." env. variables make the tool run reliably as a daemon for very long periods. Read the top part of the script for more information. --- Encrypted Tunnels with IPv6 Support: For SSH tunnelled encrypted VNC connections, one can of course use the IPv6 support in ssh(1). For SSL encrypted VNC connections, one possibility is to use the IPv6 support in stunnel(1). This includes the built-in support via the -stunnel option. For example: ``` x11vnc -stunnel SAVE -env STUNNEL_LISTEN=:: -env STUNNEL_DEBUG=1 ... ``` --- SSH IPv6 Tricks: It is interesting to note that ssh(1) can do basically the same thing as inet6to4 above by: ``` ssh -g -L 5900:localhost:5901 localhost "printf 'Press Enter to Exit: '; read x" ``` (where we have x11vnc running via "-rfbport 5901" in this case.) Note that one can also make a home-brew SOCKS5 ipv4-to-ipv6 gateway proxy using ssh like this: ``` ssh -D '*:1080' localhost "printf 'Press Enter to Exit: '; read x" ``` then specify a proxy like socks://hostname:1080 where hostname is the machine running the above ssh command (add -v to ssh for connection logging info.) --- IPv6 SSVNC Viewer: Our SSVNC VNC Viewer is basically a wrapper for ssh(1) and stunnel(1), and so it already has good IPv6 support because these two commands do. On Unix, MacOSX, and Windows nearly all of the the remaining parts of SSVNC (e.g. the built-in proxying and un-encrypted connections) have been modified to support IPv6 in SSVNC 1.0.26.

Depending on your graphics card model and x.org driver used, several approaches might work out for you: Some users [have reported](https://github.com/LibVNC/x11vnc/issues/58) that when using the 'intel' x.org driver, switching the driver's option named "AccelMethod" to "UXA" helped. Others [reported](https://github.com/LibVNC/x11vnc/issues/100) that using the 'modesetting' x.org driver caused the lags and switching to the 'intel' x.org driver helped. Some [reported](https://github.com/LibVNC/x11vnc/issues/102) that lags only occured with xfwm as window manager and with x11vnc started with monitors off, no matter what the x.org driver. In their case, one of disabling vsync, using 'modesetting' with "AccelMethod" "none" or disabling compositing all helped.

Typical usage is: Run this command in a shell on the remote machine "far-host" with X session you wish to view: x11vnc -display :0 Then run this in another window on the machine you are sitting at: vncviewer far-host:0 Once x11vnc establishes connections with the X11 server and starts listening as a VNC server it will print out a string: PORT=XXXX where XXXX is typically 5900 (the default VNC server port). One would next run something like this on the local machine: "vncviewer hostname:N" where "hostname" is the name of the machine running x11vnc and N is XXXX - 5900, i.e. usually "vncviewer hostname:0". By default x11vnc will not allow the screen to be shared and it will exit as soon as the client disconnects. See -shared and -forever below to override these protections. See the FAQ for details how to tunnel the VNC connection through an encrypted channel such as ssh(1). In brief: ssh -t -L 5900:localhost:5900 far-host 'x11vnc -localhost -display :0' vncviewer -encodings 'copyrect tight zrle hextile' localhost:0 Also, use of a VNC password (-rfbauth or -passwdfile) is strongly recommended. For additional info see: http://www.karlrunge.com/x11vnc/ and http://www.karlrunge.com/x11vnc/faq.html Config file support: if the file $HOME/.x11vncrc exists then each line in it is treated as a single command line option. Disable with -norc. For each option name, the leading character "-" is not required. E.g. a line that is either "forever" or "-forever" may be used and are equivalent. Likewise "wait 100" or "-wait 100" are acceptable and equivalent lines. The "#" character comments out to the end of the line in the usual way (backslash it for a literal). Leading and trailing whitespace is trimmed off. Lines may be continued with a "\" as the last character of a line (it becomes a space character). Options: -display disp X11 server display to connect to, usually :0. The X server process must be running on same machine and support MIT-SHM. Equivalent to setting the DISPLAY environment variable to "disp". See the description below of the "-display WAIT:..." extensions, where alias "-find" will find the user's display automatically, and "-create" will create a Xvfb session if no session is found. -auth file Set the X authority file to be "file", equivalent to setting the XAUTHORITY environment variable to "file" before startup. Same as -xauth file. See Xsecurity(7), xauth(1) man pages for more info. Use '-auth guess' to have x11vnc use its -findauth mechanism (described below) to try to guess the XAUTHORITY filename and use it. XDM/GDM/KDM: if you are running x11vnc as root and want to find the XAUTHORITY before anyone has logged into an X session yet, use: x11vnc -env FD_XDM=1 -auth guess ... (This will also find the XAUTHORITY if a user is already logged into the X session.) When running as root, FD_XDM=1 will be tried if the initial -auth guess fails. -N If the X display is :N, try to set the VNC display to also be :N This just sets the -rfbport option to 5900+N The program will exit immediately if that port is not available. The -N option only works with normal -display usage, e.g. :0 or :8, -N is ignored in the -display WAIT:..., -create, -find, -svc, -redirect, etc modes. -autoport n Automatically probe for a free VNC port starting at n. The default is to start probing at 5900. Use this to stay away from other VNC servers near 5900. -rfbport str The VNC port to listen on (a LibVNCServer option), e.g. 5900, 5901, etc. If specified as "-rfbport PROMPT" then the x11vnc -gui is used to prompt the user to enter the port number. -6 IPv6 listening support. In addition to IPv4, the IPv6 address is listened on for incoming connections. The same port number as IPv4 is used. NOTE: This x11vnc binary was compiled to have the "-6" IPv6 listening mode ENABLED by default (CPPFLAGS -DX11VNC_LISTEN6=1). So to disable IPv6 listening mode you MUST supply the "-no6" option (see below.) The "-6" mode works for both normal connections and -ssl encrypted ones. Nearly everything is supported for the IPv6 case, but there are a few exceptions. See -stunnel for its IPv6 support. Currently, for absolutely everything to work correctly the machine may need to have some IPv4 support, at the least for the loopback interface. However, for nearly all usage modes no IPv4 support is required. See -noipv4 . If you have trouble compiling or running in IPv6 mode, set -DX11VNC_IPV6=0 in CPPFLAGS when configuring to disable IPv6 support. -no6 Disable IPv6 listening support (only useful if the "-6" mode is compiled in to be the default; see the X11VNC_LISTEN6 description above under "-6".) -noipv6 Do not try to use IPv6 for any listening or connecting sockets. This includes both the listening service port(s) and outgoing connections from -connect, -connect_or_exit, or -proxy. Use this if you are having problems due to IPv6. -noipv4 Do not try to use IPv4 for any listening or connecting sockets. This is mainly for exploring the behavior of x11vnc on an IPv6-only system, but may have other uses. -reopen If the X server connection is disconnected, try to reopen the X display (up to one time.) This is of use for display managers like GDM (KillInitClients option) that kill x11vnc just after the user logs into the X session. Note: the reopened state may be unstable. Set X11VNC_REOPEN_DISPLAY=n to reopen n times and set X11VNC_REOPEN_SLEEP_MAX to the number of seconds, default 10, to keep trying to reopen the display (once per second.) Update: as of 0.9.9, x11vnc tries to automatically avoid being killed by the display manager by delaying creating windows or using XFIXES. So you shouldn't need to use KillInitClients=false as long as you log in quickly enough (within 45 seconds of connecting.) You can disable this by setting X11VNC_AVOID_WINDOWS=never. You can also set it to the number of seconds to delay. -reflect host:N Instead of connecting to and polling an X display, connect to the remote VNC server host:N and be a reflector/repeater for it. This is useful for trying to manage the case of many simultaneous VNC viewers (e.g. classroom broadcasting) where, e.g. you put a repeater on each network switch, etc, to improve performance by distributing the load and network traffic. Implies -shared (use -noshared as a later option to disable). See the discussion below under -rawfb vnc:host:N for more details. -id windowid Show the X window corresponding to "windowid" not the entire display. New windows like popup menus, transient toplevels, etc, may not be seen or may be clipped. Disabling SaveUnders or BackingStore in the X server may help show them. x11vnc may crash if the window is initially partially obscured, changes size, is iconified, etc. Some steps are taken to avoid this and the -xrandr mechanism is used to track resizes. Use xwininfo(1) to get the window id, or use "-id pick" to have x11vnc run xwininfo(1) for you and extract the id. The -id option is useful for exporting very simple applications (e.g. the current view on a webcam). -sid windowid As -id, but instead of using the window directly it shifts a root view to it: this shows SaveUnders menus, etc, although they will be clipped if they extend beyond the window. -appshare Simple application sharing based on the -id/-sid mechanism. Every new toplevel window that the application creates induces a new viewer window via a reverse connection. The -id/-sid and -connect options are required. Run 'x11vnc -appshare -help' for more info. -clip WxH+X+Y Only show the sub-region of the full display that corresponds to the rectangle geometry with size WxH and offset +X+Y. The VNC display has size WxH (i.e. smaller than the full display). This also works for -id/-sid mode where the offset is relative to the upper left corner of the selected window. An example use of this option would be to split a large (e.g. Xinerama) display into two parts to be accessed via separate viewers by running a separate x11vnc on each part. Use '-clip xinerama0' to clip to the first xinerama sub-screen (if xinerama is active). xinerama1 for the 2nd sub-screen, etc. This way you don't need to figure out the WxH+X+Y of the desired xinerama sub-screen. screens are sorted in increasing distance from the (0,0) origin (I.e. not the Xserver's order). -flashcmap In 8bpp indexed color, let the installed colormap flash as the pointer moves from window to window (slow). Also try the -8to24 option to avoid flash altogether. -shiftcmap n Rare problem, but some 8bpp displays use less than 256 colorcells (e.g. 16-color grayscale, perhaps the other bits are used for double buffering) *and* also need to shift the pixels values away from 0, .., ncells. "n" indicates the shift to be applied to the pixel values. To see the pixel values set DEBUG_CMAP=1 to print out a colormap histogram. Example: -shiftcmap 240 -notruecolor For 8bpp displays, force indexed color (i.e. a colormap) even if it looks like 8bpp TrueColor (rare problem). -advertise_truecolor If the X11 display is indexed color, lie to clients when they first connect by telling them it is truecolor. To workaround RealVNC: inPF has colourMap but not 8bpp Use '-advertise_truecolor reset' to reset client fb too. -visual n This option probably does not do what you think. It simply *forces* the visual used for the framebuffer; this may be a bad thing... (e.g. messes up colors or cause a crash). It is useful for testing and for some workarounds. n may be a decimal number, or 0x hex. Run xdpyinfo(1) for the values. One may also use "TrueColor", etc. see for a list. If the string ends in ":m" then for better or for worse the visual depth is forced to be m. You may want to use -noshm when using this option (so XGetImage may automatically translate the pixel data). -overlay Handle multiple depth visuals on one screen, e.g. 8+24 and 24+8 overlay visuals (the 32 bits per pixel are packed with 8 for PseudoColor and 24 for TrueColor). Currently -overlay only works on Solaris via XReadScreen(3X11) and IRIX using XReadDisplay(3). On Solaris there is a problem with image "bleeding" around transient popup menus (but not for the menu itself): a workaround is to disable SaveUnders by passing the "-su" argument to Xsun (in /etc/dt/config/Xservers). Use -overlay as a workaround for situations like these: Some legacy applications require the default visual to be 8bpp (8+24), or they will use 8bpp PseudoColor even when the default visual is depth 24 TrueColor (24+8). In these cases colors in some windows will be incorrect in x11vnc unless -overlay is used. Another use of -overlay is to enable showing the exact mouse cursor shape (details below). Under -overlay, performance will be somewhat slower due to the extra image transformations required. For optimal performance do not use -overlay, but rather configure the X server so that the default visual is depth 24 TrueColor and try to have all apps use that visual (e.g. some apps have -use24 or -visual options). -overlay_nocursor Sets -overlay, but does not try to draw the exact mouse cursor shape using the overlay mechanism. -8to24 [opts] Try this option if -overlay is not supported on your OS, and you have a legacy 8bpp app that you want to view on a multi-depth display with default depth 24 (and is 32 bpp) OR have a default depth 8 display with depth 24 overlay windows for some apps. This option may not work on all X servers and hardware (tested on XFree86/Xorg mga driver and Xsun). The "opts" string is not required and is described below. This mode enables a hack where x11vnc monitors windows within 3 levels from the root window. If it finds any that are 8bpp it extracts the indexed color pixel values using XGetImage() and then applies a transformation using the colormap(s) to create TrueColor RGB values that it in turn inserts into bits 1-24 of the framebuffer. This creates a depth 24 "view" of the display that is then exported via VNC. Conversely, for default depth 8 displays, the depth 24 regions are read by XGetImage() and everything is transformed and inserted into a depth 24 TrueColor framebuffer. Note that even if there are *no* depth 24 visuals or windows (i.e. pure 8bpp), this mode is potentially an improvement over -flashcmap because it avoids the flashing and shows each window in the correct color. This method works OK, but may still have bugs and it does hog resources. If there are multiple 8bpp windows using different colormaps, one may have to iconify all but one for the colors to be correct. There may be painting errors for clipping and switching between windows of depths 8 and 24. Heuristics are applied to try to minimize the painting errors. One can also press 3 Alt_L's in a row to refresh the screen if the error does not repair itself. Also the option -fixscreen 8=3.0 or -fixscreen V=3.0 may be used to periodically refresh the screen at the cost of bandwidth (every 3 sec for this example). The [opts] string can contain the following settings. Multiple settings are separated by commas. For for some X servers with default depth 24 a speedup may be achieved via the option "nogetimage". This enables a scheme were XGetImage() is not used to retrieve the 8bpp data. Instead, it assumes that the 8bpp data is in bits 25-32 of the 32bit X pixels. There is no requirement that the X server should put the data there for our poll requests, but some do and so the extra steps to retrieve it can be skipped. Tested with mga driver with XFree86/Xorg. For the default depth 8 case this option is ignored. To adjust how often XGetImage() is used to poll the non-default visual regions for changes, use the option "poll=t" where "t" is a floating point time. (default: 0.05) Setting the option "level2" will limit the search for non-default visual windows to two levels from the root window. Do this on slow machines where you know the window manager only imposes one extra window between the app window and the root window. Also for very slow machines use "cachewin=t" where t is a floating point amount of time to cache XGetWindowAttributes results. E.g. cachewin=5.0. This may lead to the windows being unnoticed for this amount of time when deiconifying, painting errors, etc. While testing on a very old SS20 these options gave tolerable response: -8to24 poll=0.2,cachewin=5.0. For this machine -overlay is supported and gives better response. Debugging for this mode can be enabled by setting "dbg=1", "dbg=2", or "dbg=3". -24to32 Very rare problem: if the framebuffer (X display or -rawfb) is 24bpp instead of the usual 32bpp, then dynamically transform the pixels to 32bpp. This will be slower, but can be used to work around problems where VNC viewers cannot handle 24bpp (e.g. "main: setPF: not 8, 16 or 32 bpp?"). See the FAQ for more info. In the case of -rawfb mode, the pixels are directly modified by inserting a 0 byte to pad them out to 32bpp. For X displays, a kludge is done that is equivalent to "-noshm -visual TrueColor:32". (If better performance is needed for the latter, feel free to ask). -scale fraction Scale the framebuffer by factor "fraction". Values less than 1 shrink the fb, larger ones expand it. Note: the image may not be sharp and response may be slower. If "fraction" contains a decimal point "." it is taken as a floating point number, alternatively the notation "m/n" may be used to denote fractions exactly, e.g. -scale 2/3 To scale asymmetrically in the horizontal and vertical directions, specify a WxH geometry to stretch to: e.g. '-scale 1024x768', or also '-scale 0.9x0.75' Scaling Options: can be added after "fraction" via ":", to supply multiple ":" options use commas. If you just want a quick, rough scaling without blending, append ":nb" to "fraction" (e.g. -scale 1/3:nb). No blending is the default for 8bpp indexed color, to force blending for this case use ":fb". To disable -scrollcopyrect and -wirecopyrect under -scale use ":nocr". If you need to to enable them use ":cr" or specify them explicitly on the command line. If a slow link is detected, ":nocr" may be applied automatically. Default: :cr More esoteric options: for compatibility with vncviewers the scaled width is adjusted to be a multiple of 4: to disable this use ":n4". ":in" use interpolation scheme even when shrinking, ":pad" pad scaled width and height to be multiples of scaling denominator (e.g. 3 for 2/3). -geometry WxH Same as -scale WxH -scale_cursor frac By default if -scale is supplied the cursor shape is scaled by the same factor. Depending on your usage, you may want to scale the cursor independently of the screen or not at all. If you specify -scale_cursor the cursor will be scaled by that factor. When using -scale mode to keep the cursor at its "natural" size use "-scale_cursor 1". Most of the ":" scaling options apply here as well. -viewonly All VNC clients can only watch (default off). -shared VNC display is shared, i.e. more than one viewer can connect at the same time (default off). -once Exit after the first successfully connected viewer disconnects, opposite of -forever. This is the Default. -forever Keep listening for more connections rather than exiting as soon as the first client(s) disconnect. Same as -many To get the standard non-shared VNC behavior where when a new VNC client connects the existing VNC client is dropped use: -nevershared -forever This method can also be used to guard against hung TCP connections that do not go away. -loop Create an outer loop restarting the x11vnc process whenever it terminates. -bg and -inetd are ignored in this mode (however see -loopbg below). Useful for continuing even if the X server terminates and restarts (at that moment the process will need permission to reconnect to the new X server of course). Use, e.g., -loop100 to sleep 100 millisecs between restarts, etc. Default is 2000ms (i.e. 2 secs) Use, e.g. -loop300,5 to sleep 300 ms and only loop 5 times. If -loopbg (plus any numbers) is specified instead, the "-bg" option is implied and the mode approximates inetd(8) usage to some degree. In this case when it goes into the background any listening sockets (i.e. ports 5900, 5800) are closed, so the next one in the loop can use them. This mode will only be of use if a VNC client (the only client for that process) is already connected before the process goes into the background, for example, usage of -display WAIT:.., -svc, and -connect can make use of this "poor man's" inetd mode. The default wait time is 500ms in this mode. This usage could use useful: -svc -bg -loopbg -timeout n Exit unless a client connects within the first n seconds after startup. If there have been no connection attempts after n seconds x11vnc exits immediately. If a client is trying to connect but has not progressed to the normal operating state, x11vnc gives it a few more seconds to finish and exits if it does not make it to the normal state. For reverse connections via -connect or -connect_or_exit a timeout of n seconds will be set for all reverse connects. If the connect timeout alarm goes off, x11vnc will exit immediately. -sleepin n At startup sleep n seconds before proceeding (e.g. to allow redirs and listening clients to start up) If a range is given: '-sleepin min-max', a random value between min and max is slept. E.g. '-sleepin 0-20' and '-sleepin 10-30'. Floats are allowed too. -inetd Launched by inetd(8): stdio instead of listening socket. Note: if you are not redirecting stderr to a log file (via shell 2> or -o option) you MUST also specify the -q option, otherwise the stderr goes to the viewer which will cause it to abort. Specifying both -inetd and -q and no -o will automatically close the stderr. -tightfilexfer Enable the TightVNC file transfer extension. Note that that when the -viewonly option is supplied all file transfers are disabled. Also clients that log in viewonly cannot transfer files. However, if the remote control mechanism is used to change the global or per-client viewonly state the filetransfer permissions will NOT change. IMPORTANT: please understand if -tightfilexfer is specified and you run x11vnc as root for, say, inetd or display manager (gdm, kdm, ...) access and you do not have it switch users via the -users option, then VNC Viewers that connect are able to do filetransfer reads and writes as *root*. Also, tightfilexfer is disabled in -unixpw mode. -ultrafilexfer Note: to enable UltraVNC filetransfer and to get it to work you probably need to supply these LibVNCServer options: "-rfbversion 3.6 -permitfiletransfer" "-ultrafilexfer" is an alias for this combination. IMPORTANT: please understand if -ultrafilexfer is specified and you run x11vnc as root for, say, inetd or display manager (gdm, kdm, ...) access and you do not have it switch users via the -users option, then VNC Viewers that connect are able to do filetransfer reads and writes as *root*. Note that sadly you cannot do both -tightfilexfer and -ultrafilexfer at the same time because the latter requires setting the version to 3.6 and tightvnc will not do filetransfer when it sees that version number. -http Instead of using -httpdir (see below) to specify where the Java vncviewer applet is, have x11vnc try to *guess* where the directory is by looking relative to the program location and in standard locations (/usr/local/share/x11vnc/classes, etc). Under -ssl or -stunnel the ssl classes subdirectory is sought. -http_ssl As -http, but force lookup for ssl classes subdir. Note that for HTTPS, single-port Java applet delivery you can set X11VNC_HTTPS_DOWNLOAD_WAIT_TIME to the max number of seconds to wait for the applet download to finish. The default is 15. -avahi Use the Avahi/mDNS ZeroConf protocol to advertise this VNC server to the local network. (Related terms: Rendezvous, Bonjour). Depending on your setup, you may need to start avahi-daemon and open udp port 5353 in your firewall. You can set X11VNC_AVAHI_NAME, X11VNC_AVAHI_HOST, and/or X11VNC_AVAHI_PORT environment variables to override the default values. For example: -env X11VNC_AVAHI_NAME=wally If the avahi API cannot be found at build time, a helper program like avahi-publish(1) or dns-sd(1) will be tried -mdns Same as -avahi. -zeroconf Same as -avahi. -connect string For use with "vncviewer -listen" reverse connections. If "string" has the form "host" or "host:port" the connection is made once at startup. Use commas for a list of host's and host:port's. E.g. -connect host1,host2 or host1:0,host2:5678. Note that to reverse connect to multiple hosts at the same time you will likely need to also supply: -shared Note that unlike most vnc servers, x11vnc will require a password for reverse as well as for forward connections. (provided password auth has been enabled, -rfbauth, etc) If you do not want to require a password for reverse connections set X11VNC_REVERSE_CONNECTION_NO_AUTH=1 in your environment before starting x11vnc. If "string" contains "/" it is instead interpreted as a file to periodically check for new hosts. The first line is read and then the file is truncated. Be careful about the location of this file if x11vnc is running as root (e.g. via gdm(1), etc). Repeater mode: Some services provide an intermediate "vnc repeater": http://www.uvnc.com/addons/repeater.html (and also http://koti.mbnet.fi/jtko/ for linux port) that acts as a proxy/gateway. Modes like these require an initial string to be sent for the reverse connection before the VNC protocol is started. Here are the ways to do this: -connect pre=some_string+host:port -connect pre128=some_string+host:port -connect repeater=ID:1234+host:port -connect repeater=23.45.67.89::5501+host:port SSVNC notation is also supported: -connect repeater://host:port+ID:1234 As with normal -connect usage, if the repeater port is not supplied 5500 is assumed. The basic idea is between the special tag, e.g. "pre=" and "+" is the pre-string to be sent. Note that in this case host:port is the repeater server, NOT the vnc viewer. Somehow the pre-string tells the repeater server how to find the vnc viewer and connect you to it. In the case pre=some_string+host:port, "some_string" is simply sent. In the case preNNN=some_string+host:port "some_string" is sent in a null padded buffer of length NNN. repeater= is the same as pre250=, this is the ultravnc repeater buffer size. Strings like "\n" and "\r", etc. are expanded to newline and carriage return. "\c" is expanded to "," since the connect string is comma separated. See also the -proxy option below for additional ways to plumb reverse connections. Reverse SSL: using -connect in -ssl mode makes x11vnc act as an SSL client (initiates SSL connection) rather than an SSL server. The idea is x11vnc might be connecting to stunnel on the viewer side with the viewer in listening mode. If you do not want this behavior, use -env X11VNC_DISABLE_SSL_CLIENT_MODE=1. With this the viewer side can act as the SSL client as it normally does for forward connections. Reverse SSL Repeater mode: This will work, but note that if the VNC Client does any sort of a 'Fetch Cert' action before connecting, then the Repeater will likely drop the connection and both sides will need to restart. Consider the use of -connect_or_exit and -loop300,2 to have x11vnc reconnect once to the repeater after the fetch. You will probably also want to supply -sslonly to avoid x11vnc thinking the delay in response means the connection is VeNCrypt. The env var X11VNC_DISABLE_SSL_CLIENT_MODE=1 discussed above may also be useful (i.e. the viewer can do a forward connection as it normally does.) IPv6: as of x11vnc 0.9.10 the -connect option should connect to IPv6 hosts properly. If there are problems you can disable IPv6 by setting -DX11VNC_IPV6=0 in CPPFLAGS when configuring. If there problems connecting to IPv6 hosts consider a relay like the included inet6to4 script or the -proxy option. -connect_or_exit str As with -connect, except if none of the reverse connections succeed, then x11vnc shuts down immediately An easier to type alias for this option is '-coe' By the way, if you do not want x11vnc to listen on ANY interface use -rfbport 0 which is handy for the -connect_or_exit mode. -proxy string Use proxy in string (e.g. host:port) as a proxy for making reverse connections (-connect or -connect_or_exit options). Web proxies are supported, but note by default most of them only support destination connections to ports 443 or 563, so this might not be very useful (the viewer would need to listen on that port or the router would have to do a port redirection). A web proxy may be specified by either "host:port" or "http://host:port" (the port is required even if it is the common choices 80 or 8080) SOCKS4, SOCKS4a, and SOCKS5 are also supported. SOCKS proxies normally do not have restrictions on the destination port number. Use a format like this: socks://host:port or socks5://host:port. Note that ssh -D does not support SOCKS4a, so use socks5://. For socks:// SOCKS4 is used on a numerical IP and "localhost", otherwise SOCKS4a is used (and so the proxy tries to do the DNS lookup). An experimental mode is "-proxy http://host:port/..." Note the "/" after the port that distinguishes it from a normal web proxy. The port must be supplied even if it is the default 80. For this mode a GET is done to the supplied URL with the string host=H&port=P appended. H and P will be the -connect reverse connect host and port. Use the string "__END__" to disable the appending. The basic idea here is that maybe some cgi script provides the actual viewer hookup and tunnelling. How to actually achieve this within cgi, php, etc. is not clear... A custom web server or apache module would be straight-forward. Another experimental mode is "-proxy ssh://user@host" in which case a SSH tunnel is used for the proxying. "user@" is not needed unless your unix username is different on "host". For a non-standard SSH port use ssh://user@host:port. If proxies are chained (see next paragraph) then the ssh one must be the first one. If ssh-agent is not active, then the ssh password needs to be entered in the terminal where x11vnc is running. Examples: -connect localhost:0 -proxy ssh://me@friends-pc:2222 -connect snoopy:0 -proxy ssh://ssh.company.com Multiple proxies may be chained together in case one needs to ricochet off of a number of hosts to finally reach the VNC viewer. Up to 3 may be chained, separate them by commas in the order they are to be connected to. E.g.: http://host1:port1,socks5://host2:port2 or three like: first,second,third IPv6: as of x11vnc 0.9.10 the -proxy option should connect to IPv6 hosts properly. If there are problems you can disable IPv6 by setting -DX11VNC_IPV6=0 in CPPFLAGS when configuring. If there problems connecting to IPv6 hosts consider a relay like the included inet6to4 script. -vncconnect Monitor the VNC_CONNECT X property set by the standard -novncconnect VNC program vncconnect(1). When the property is set to "host" or "host:port" establish a reverse connection. Using xprop(1) instead of vncconnect may work (see the FAQ). The -remote control mechanism uses X11VNC_REMOTE channel, and this option disables/enables it as well. Default: -vncconnect To use different names for these X11 properties (e.g. to have separate communication channels for multiple x11vnc's on the same display) set the VNC_CONNECT or X11VNC_REMOTE env. vars. to the string you want, for example: -env X11VNC_REMOTE=X11VNC_REMOTE_12345 Both sides of the channel must use the same unique name. The same can be done for the internal X11VNC_TICKER property (heartbeat and timestamp) if desired. -allow host1[,host2..] Only allow client connections from hosts matching the comma separated list of hostnames or IP addresses. Can also be a numerical IP prefix, e.g. "192.168.100." to match a simple subnet, for more control build LibVNCServer with libwrap support (See the FAQ). If the list contains a "/" it instead is a interpreted as a file containing addresses or prefixes that is re-read each time a new client connects. Lines can be commented out with the "#" character in the usual way. -allow applies in -ssl mode, but not in -stunnel mode. IPv6: as of x11vnc 0.9.10 a host can be specified in IPv6 numerical format, e.g. 2001:4860:b009::93. -localhost Basically the same as "-allow 127.0.0.1". Note: if you want to restrict which network interface x11vnc listens on, see the -listen option below. E.g. "-listen localhost" or "-listen 192.168.3.21". As a special case, the option "-localhost" implies "-listen localhost". A rare case, but for non-localhost -listen usage, if you use the remote control mechanism (-R) to change the -listen interface you may need to manually adjust the -allow list (and vice versa) to avoid situations where no connections (or too many) are allowed. If you do not want x11vnc to listen on ANY interface (evidently you are using -connect or -connect_or_exit, or plan to use remote control: -R connect:host), use -rfbport 0 IPv6: if IPv6 is supported, this option automatically implies the IPv6 loopback address '::1' as well. -unixsock str Listen on the unix socket (AF_UNIX) 'str' for connections. This mode is for either local connections or a tunnel endpoint where one wants the file permission of the unix socket file to determine what can connect to it. (This currently requires an edit to libvnserver/rfbserver.c: comment out lines 310 and 311, 'close(sock)' and 'return NULL' in rfbserver.c after the setsockopt() call.) Note that to disable all tcp listening ports specify '-rfbport 0' and should be useful with this mode. Example: mkdir ~/s; chmod 700 ~/s; x11vnc -unixsock ~/s/mysock -rfbport 0 ... The SSVNC unix vncviewer can connect to unix sockets. -listen6 str When in IPv6 listen mode "-6", listen only on the network interface with address "str". It also works for link scope addresses (fe80::219:dbff:fee5:3f92%eth0) and IPv6 hostname strings (e.g. ipv6.google.com.) Use LibVNCServer -listen option for the IPv4 interface. -nolookup Do not use gethostbyname() or gethostbyaddr() to look up host names or IP numbers. Use this if name resolution is incorrectly set up and leads to long pauses as name lookups time out, etc. -input string Fine tuning of allowed user input. If "string" does not contain a comma "," the tuning applies only to normal clients. Otherwise the part before "," is for normal clients and the part after for view-only clients. "K" is for Keystroke input, "M" for Mouse-motion input, "B" for Button-click input, "C" is for Clipboard input, and "F" is for File transfer (ultravnc only). Their presence in the string enables that type of input. E.g. "-input M" means normal users can only move the mouse and "-input KMBCF,M" lets normal users do anything and enables view-only users to move the mouse. This option is ignored when a global -viewonly is in effect (all input is discarded in that case). -grabkbd When VNC viewers are connected, attempt to the grab the keyboard so a (non-malicious) user sitting at the physical display is not able to enter keystrokes. This method uses XGrabKeyboard(3X11) and so it is not secure and does not rule out the person at the physical display injecting keystrokes by flooding the server with them, grabbing the keyboard himself, etc. Some degree of cooperation from the person at the display is assumed. This is intended for remote help-desk or educational usage modes. Note: on some recent (12/2010) X servers and/or desktops, -grabkbd no longer works: it prevents the window manager from resizing windows and similar things. Try -ungrabboth below (might not work.) -grabptr As -grabkbd, but for the mouse pointer using XGrabPointer(3X11). Unfortunately due to the way the X server works, the mouse can still be moved around by the user at the physical display, but he will not be able to change window focus with it. Also some window managers that call XGrabServer(3X11) for resizes, etc, will act on the local user's input. Again, some degree of cooperation from the person at the display is assumed. -ungrabboth Whenever there is any input (either keyboard or pointer), ungrab *both* the keyboard and the pointer while injecting the synthetic input. This is to allow window managers, etc. a chance to grab. -grabalways Apply both -grabkbd and -grabptr even when no VNC viewers are connected. If you only want one of them, use the -R remote control to turn the other back on, e.g. -R nograbptr. -viewpasswd string Supply a 2nd password for view-only logins. The -passwd (full-access) password must also be supplied. -passwdfile filename Specify the LibVNCServer password via the first line of the file "filename" (instead of via -passwd on the command line where others might see it via ps(1)). See the descriptions below for how to supply multiple passwords, view-only passwords, to specify external programs for the authentication, and other features. If the filename is prefixed with "rm:" it will be removed after being read. Perhaps this is useful in limiting the readability of the file. In general, the password file should not be readable by untrusted users (BTW: neither should the VNC -rfbauth file: it is NOT encrypted, only obscured with a fixed key). If the filename is prefixed with "read:" it will periodically be checked for changes and reread. It is guaranteed to be reread just when a new client connects so that the latest passwords will be used. If "filename" is prefixed with "cmd:" then the string after the ":" is run as an external command: the output of the command will be interpreted as if it were read from a password file (see below). If the command does not exit with 0, then x11vnc terminates immediately. To specify more than 1000 passwords this way set X11VNC_MAX_PASSWDS before starting x11vnc. The environment variables are set as in -accept. Note that due to the VNC protocol only the first 8 characters of a password are used (DES key). If "filename" is prefixed with "custom:" then a custom password checker is supplied as an external command following the ":". The command will be run when a client authenticates. If the command exits with 0 the client is accepted, otherwise it is rejected. The environment variables are set as in -accept. The standard input to the custom command will be a decimal digit "len" followed by a newline. "len" specifies the challenge size and is usually 16 (the VNC spec). Then follows len bytes which is the random challenge string that was sent to the client. This is then followed by len more bytes holding the client's response (i.e. the challenge string encrypted via DES with the user password in the standard situation). The "custom:" scheme can be useful to implement dynamic passwords or to implement methods where longer passwords and/or different encryption algorithms are used. The latter will require customizing the VNC client as well. One could create an MD5SUM based scheme for example. File format for -passwdfile: If multiple non-blank lines exist in the file they are all taken as valid passwords. Blank lines are ignored. Password lines may be "commented out" (ignored) if they begin with the character "#" or the line contains the string "__SKIP__". Lines may be annotated by use of the "__COMM__" string: from it to the end of the line is ignored. An empty password may be specified via the "__EMPTY__" string on a line by itself (note your viewer might not accept empty passwords). If the string "__BEGIN_VIEWONLY__" appears on a line by itself, the remaining passwords are used for viewonly access. For compatibility, as a special case if the file contains only two password lines the 2nd one is automatically taken as the viewonly password. Otherwise the "__BEGIN_VIEWONLY__" token must be used to have viewonly passwords. (tip: make the 3rd and last line be "__BEGIN_VIEWONLY__" to have 2 full-access passwords) -showrfbauth filename Print to the screen the obscured VNC password kept in the rfbauth file "filename" and then exit. -unixpw [list] Use Unix username and password authentication. x11vnc will use the su(1) program to verify the user's password. [list] is an optional comma separated list of allowed Unix usernames. If the [list] string begins with the character "!" then the entire list is taken as an exclude list. See below for per-user options that can be applied. A familiar "login:" and "Password:" dialog is presented to the user on a black screen inside the vncviewer. The connection is dropped if the user fails to supply the correct password in 3 tries or does not send one before a 45 second timeout. Existing clients are view-only during this period. If the first character received is "Escape" then the unix username will not be displayed after "login:" as it is typed. This could be of use for VNC viewers that automatically type the username and password. Since the detailed behavior of su(1) can vary from OS to OS and for local configurations, test the mode before deployment to make sure it is working properly. x11vnc will attempt to be conservative and reject a login if anything abnormal occurs. One case to note: FreeBSD and the other BSD's by default it is impossible for the user running x11vnc to validate his *own* password via su(1) (commenting out the pam_self.so entry in /etc/pam.d/su eliminates this behavior). So the x11vnc login will always *FAIL* for this case (even when the correct password is supplied). A possible workaround for this on *BSD would be to start x11vnc as root with the "-users +nobody" option to immediately switch to user nobody where the su'ing will proceed normally. Another source of potential problems are PAM modules that prompt for extra info, e.g. password aging modules. These logins will fail as well even when the correct password is supplied. **IMPORTANT**: to prevent the Unix password being sent in *clear text* over the network, one of two schemes will be enforced: 1) the -ssl builtin SSL mode, or 2) require both -localhost and -stunnel be enabled. Method 1) ensures the traffic is encrypted between viewer and server. A PEM file will be required, see the discussion under -ssl below (under some circumstances a temporary one can be automatically generated). Method 2) requires the viewer connection to appear to come from the same machine x11vnc is running on (e.g. from a ssh -L port redirection). And that the -stunnel SSL mode be used for encryption over the network. (see the description of -stunnel below). Note: as a convenience, if you ssh(1) in and start x11vnc it will check if the environment variable SSH_CONNECTION is set and appears reasonable. If it does, then the -ssl or -stunnel requirement will be dropped since it is assumed you are using ssh for the encrypted tunnelling. -localhost is still enforced. Use -ssl or -stunnel to force SSL usage even if SSH_CONNECTION is set. To override the above restrictions you can set environment variables before starting x11vnc: Set UNIXPW_DISABLE_SSL=1 to disable requiring either -ssl or -stunnel (as under SSH_CONNECTION.) Evidently you will be using a different method to encrypt the data between the vncviewer and x11vnc: perhaps ssh(1) or an IPSEC VPN. -localhost is still enforced (however, see the next paragraph.) Set UNIXPW_DISABLE_LOCALHOST=1 to disable the -localhost requirement in -unixpw modes. One should never do this (i.e. allow the Unix passwords to be sniffed on the network.) This also disables the localhost requirement for reverse connections (see below.) Note that use of -localhost with ssh(1) (and no -unixpw) is roughly the same as requiring a Unix user login (since a Unix password or the user's public key authentication is used by sshd on the machine where x11vnc runs and only local connections from that machine are accepted). Regarding reverse connections (e.g. -R connect:host and -connect host), when the -localhost constraint is in effect then reverse connections can only be used to connect to the same machine x11vnc is running on (default port 5500). Please use a ssh or stunnel port redirection to the viewer machine to tunnel the reverse connection over an encrypted channel. In -inetd mode the Method 1) will be enforced (not Method 2). With -ssl in effect reverse connections are disabled. If you override this via env. var, be sure to also use encryption from the viewer to inetd. Tip: you can also have your own stunnel spawn x11vnc in -inetd mode (thereby bypassing inetd). See the FAQ for details. The user names in the comma separated [list] may have per-user options after a ":", e.g. "fred:opts" where "opts" is a "+" separated list of "viewonly", "fullaccess", "input=XXXX", or "deny", e.g. "karl,wally:viewonly,boss:input=M". For "input=" it is the K,M,B,C described under -input. If an item in the list is "*" that means those options apply to all users. It ALSO implies all users are allowed to log in after supplying a valid password. Use "deny" to explicitly deny some users if you use "*" to set a global option. If [list] begins with the "!" character then "*" is ignored for checking if the user is allowed, but the option values associated with it do apply as normal. There are also some utilities for checking passwords if [list] starts with the "%" character. See the quick_pw() function for more details. Description: "%-" or "%stdin" means read one line from stdin. "%env" means it is in $UNIXPW env var. A leading "%/" or "%." means read the first line from the filename that follows after the % character. % by itself means prompt for the username and password. Otherwise: %user:pass E.g. -unixpw %fred:swordfish For the other cases user:pass is read from the indicated source. If the password is correct 'Y user' is printed and the program exit code is 0. If the password is incorrect it prints 'N user' and the exit code is 1. If there is some other error the exit code is 2. This feature enables x11vnc to be a general unix user password checking tool; it could be used from scripts or other programs. These % password checks also apply to the -unixpw_nis and -unixpw_cmd options. For the % password check, if the env. var. UNIXPW_CMD is set to a command then it is run as the user (assuming the password is correct.) The output of the command is not printed, the program or script must manage that by some other means. The exit code of x11vnc will depend on the exit code of the command that is run. Use -nounixpw to disable unixpw mode if it was enabled earlier in the cmd line (e.g. -svc mode) -unixpw_nis [list] As -unixpw above, however do not use su(1) but rather use the traditional getpwnam(3) + crypt(3) method to verify passwords. All of the above -unixpw options and constraints apply. This mode requires that the encrypted passwords be readable. Encrypted passwords stored in /etc/shadow will be inaccessible unless x11vnc is run as root. This is called "NIS" mode simply because in most NIS setups user encrypted passwords are accessible (e.g. "ypcat passwd") by an ordinary user and so that user can authenticate ANY user. NIS is not required for this mode to work (only that getpwnam(3) return the encrypted password is required), but it is unlikely it will work (as an ordinary user) for most modern environments unless NIS is available. On the other hand, when x11vnc is run as root it will be able to to access /etc/shadow even if NIS is not available (note running as root is often done when running x11vnc from inetd and xdm/gdm/kdm). Looked at another way, if you do not want to use the su(1) method provided by -unixpw (i.e. su_verify()), you can run x11vnc as root and use -unixpw_nis. Any users with passwords in /etc/shadow can then be authenticated. In -unixpw_nis mode, under no circumstances is x11vnc's user password verifying function based on su called (i.e. the function su_verify() that runs /bin/su in a pseudoterminal to verify passwords.) However, if -unixpw_nis is used in conjunction with the -find and -create -display WAIT:... modes then, if x11vnc is running as root, /bin/su may be called externally to run the find or create commands. -unixpw_cmd cmd As -unixpw above, however do not use su(1) but rather run the externally supplied command "cmd". The first line of its stdin will be the username and the second line the received password. If the command exits with status 0 (success) the VNC user will be accepted. It will be rejected for any other return status. Dynamic passwords and non-unix passwords, e.g. LDAP, can be implemented this way by providing your own custom helper program. Note that the remote viewer is given 3 tries to enter the correct password, and so the program may be called in a row that many (or more) times. If a list of allowed users is needed to limit who can log in, use -unixpw [list] in addition to this option. In FINDDISPLAY and FINDCREATEDISPLAY modes the "cmd" will also be run with the RFB_UNIXPW_CMD_RUN env. var. non-empty and set to the corresponding display find/create command. The first two lines of input are the username and passwd as in the normal case described above. To support FINDDISPLAY and FINDCREATEDISPLAY, "cmd" should run the requested command as the user (and most likely refusing to run it if the password is not correct.) Here is an example script (note it has a hardwired bogus password "abc"!) #!/bin/sh # Example x11vnc -unixpw_cmd script. # Read the first two lines of stdin (user and passwd) read user read pass debug=0 if [ $debug = 1 ]; then echo "user: $user" 1>&2 echo "pass: $pass" 1>&2 env | egrep -i 'rfb|vnc' 1>&2 fi # Check if the password is valid. # (A real example would use ldap lookup, etc!) if [ "X$pass" != "Xabc" ]; then exit 1 # incorrect password fi if [ "X$RFB_UNIXPW_CMD_RUN" = "X" ]; then exit 0 # correct password else # Run the requested command (finddisplay) if [ $debug = 1 ]; then echo "run: $RFB_UNIXPW_CMD_RUN" 1>&2 fi exec /bin/su - "$user" -c "$RFB_UNIXPW_CMD_RUN" fi In -unixpw_cmd mode, under no circumstances is x11vnc's user password verifying function based on su called (i.e. the function su_verify() that runs /bin/su in a pseudoterminal to verify passwords.) It is up to the supplied unixpw_cmd to do user switching if desired and if it has the permissions to do so. -find Find the user's display using FINDDISPLAY. This is an alias for "-display WAIT:cmd=FINDDISPLAY". Note: if a -display occurs later on the command line it will override the -find setting. For this and the next few options see -display WAIT:... below for all of the details. -finddpy Run the FINDDISPLAY program, print out the found display (if any) and exit. Output is like: DISPLAY=:0.0 DISPLAY=:0.0,XPID=12345 or DISPLAY=:0.0,VT=7. XPID is the process ID of the found X server. VT is the Linux virtual terminal of the X server. -listdpy Have the FINDDISPLAY program list all of your displays (i.e. all the X displays on the local machine that you have access rights to). x11vnc then exits. -findauth [disp] Apply the -find/-finddpy heuristics to try to guess the XAUTHORITY file for DISPLAY 'disp'. If 'disp' is not supplied, then the value in the -display on the cmdline is used; failing that $DISPLAY is used; and failing that ":0" is used. x11vnc then exits. If nothing is printed out, that means no XAUTHORITY was found for 'disp'; i.e. failure. If "XAUTHORITY=" is printed out, that means use the default (i.e. do not set XAUTHORITY). If "XAUTHORITY=/path/to/file" is printed out, then use that file. XDM/GDM/KDM: if you are running x11vnc as root and want to find the XAUTHORITY before anyone has logged into an X session yet, use: x11vnc -env FD_XDM=1 -findauth ... (This will also find the XAUTHORITY if a user is already logged into the X session.) When running as root, FD_XDM=1 will be tried if the initial -findauth fails. -create First try to find the user's display using FINDDISPLAY, if that doesn't succeed create an X session via the FINDCREATEDISPLAY method. This is an alias for "-display WAIT:cmd=FINDCREATEDISPLAY-Xvfb". Note: if a -display occurs later on the command line it will override the -create setting. SSH NOTE: for both -find and -create you can (should!) add the "-localhost" option to force SSH tunnel access. -xdummy As in -create, except Xdummy instead of Xvfb. -xvnc As in -create, except Xvnc instead of Xvfb. -xvnc_redirect As in -create, except Xvnc.redirect instead of Xvfb. -xdummy_xvfb Sets WAIT:cmd=FINDCREATEDISPLAY-Xdummy,Xvfb -create_xsrv str Sets WAIT:cmd=FINDCREATEDISPLAY- Can be on cmdline after anything that sets WAIT:.. and other things (e.g. -svc, -xdmsvc) to adjust the X server list. Example: -svc ... -create_xsrv Xdummy,X -svc Terminal services mode based on SSL access. Alias for -display WAIT:cmd=FINDCREATEDISPLAY-Xvfb -unixpw -users unixpw= -ssl SAVE Also "-service". Note: if a -display, -unixpw, -users, or -ssl occurs later on the command line it will override the -svc setting. -svc_xdummy As -svc except Xdummy instead of Xvfb. -svc_xvnc As -svc except Xvnc instead of Xvfb. -svc_xdummy_xvfb As -svc with Xdummy,Xvfb. -xdmsvc Display manager Terminal services mode based on SSL. Alias for -display WAIT:cmd=FINDCREATEDISPLAY-Xvfb.xdmcp -unixpw -users unixpw= -ssl SAVE Also "-xdm_service". Note: if a -display, -unixpw, -users, or -ssl occurs later on the command line it will override the -xdmsvc setting. To create a session a user will have to first log in to the -unixpw dialog and then log in again to the XDM/GDM/KDM prompt. Subsequent re-connections will only require the -unixpw password. See the discussion under -display WAIT:... for more details about XDM, etc configuration. Remember to enable XDMCP in the xdm-config, gdm.conf, or kdmrc configuration file. See -display WAIT: for more info. -sshxdmsvc Display manager Terminal services mode based on SSH. Alias for -display WAIT:cmd=FINDCREATEDISPLAY-Xvfb.xdmcp -localhost. The -localhost option constrains connections to come in via a SSH tunnel (which will require a login). To create a session a user will also have to log into the XDM GDM KDM prompt. Subsequent re-connections will only only require the SSH login. See the discussion under -display WAIT:... for more details about XDM, etc configuration. Remember to enable XDMCP in the xdm-config, gdm.conf, or kdmrc configuration file. See -display WAIT: for more info. -unixpw_system_greeter Present a "Press 'Escape' for System Greeter" option to the connecting VNC client in combined -unixpw and xdmcp FINDCREATEDISPLAY modes (e.g. -xdmsvc). Normally in a -unixpw mode the VNC client must supply a valid username and password to gain access. However, if -unixpw_system_greeter is supplied AND the FINDCREATEDISPLAY command matches 'xdmcp', then the user has the option to press Escape and then get a XDM/GDM/KDM login/greeter panel instead. They will then supply a username and password directly to the greeter. Otherwise, in xdmcp FINDCREATEDISPLAY mode the user must supply his username and password TWICE. First to the initial unixpw login dialog, and second to the subsequent XDM/GDM/KDM greeter. Note that if the user re-connects and supplies his username and password in the unixpw dialog the xdmcp greeter is skipped and he is connected directly to his existing X session. So the -unixpw_system_greeter option avoids the extra password at X session creation time. Example: x11vnc -xdmsvc -unixpw_system_greeter See -unixpw and -display WAIT:... for more info. The special options after a colon at the end of the username (e.g. user:solid) described under -display WAIT: are also applied in this mode if they are typed in before the user hits Escape. The username is ignored but the colon options are not. The default message is 2 lines in a small font, set the env. var. X11VNC_SYSTEM_GREETER1=true for a 1 line message in a larger font. If the user pressed Escape the FINDCREATEDISPLAY command will be run with the env. var. X11VNC_XDM_ONLY=1. Remember to enable XDMCP in the xdm-config, gdm.conf, or kdmrc configuration file. See -display WAIT: for more info. -redirect port As in FINDCREATEDISPLAY-Xvnc.redirect mode except redirect immediately (i.e. without X session finding or creation) to a VNC server listening on port. You can also supply host:port to redirect to a different machine. If 0 <= port < 200 it is taken as a VNC display (5900 is added to get the actual port), if port < 0 then -port is used. Probably the only reason to use the -redirect option is in conjunction with SSL support, e.g. -ssl SAVE. This provides an easy way to add SSL encryption to a VNC server that does not support SSL (e.g. Xvnc or vnc.so) In fact, the protocol does not even need to be VNC, and so "-rfbport port1 -ssl SAVE -redirect host:port2" can act as a replacement for stunnel(1). This mode only allows one redirected connection. The -forever option does not apply. Use -inetd or -loop for persistent service. -display_WAIT :... A special usage mode for the normal -display option. Useful with -unixpw, but can be used independently of it. If the display string begins with WAIT: then x11vnc waits until a VNC client connects before opening the X display (or -rawfb device). This could be useful for delaying opening the display for certain usage modes (say if x11vnc is started at boot time and no X server is running or users logged in yet). If the string is, e.g. WAIT:0.0 or WAIT:1, i.e. "WAIT" in front of a normal X display, then that indicated display is used. One can also insert a geometry between colons, e.g. WAIT:1280x1024:... to set the size of the display the VNC client first attaches to since some VNC viewers will not automatically adjust to a new framebuffer size. A more interesting case is like this: WAIT:cmd=/usr/local/bin/find_display in which case the command after "cmd=" is run to dynamically work out the DISPLAY and optionally the XAUTHORITY data. The first line of the command output must be of the form DISPLAY=. On Linux if the virtual terminal is known append ",VT=n" to this string and the chvt(1) program will also be run. Any remaining output is taken as XAUTHORITY data. It can be either of the form XAUTHORITY= or raw xauthority data for the display. For example; xauth extract - $DISPLAY" NOTE: As specified in the previous paragraph, you can supply your own WAIT:cmd=... program or script, BUT there are two very useful *BUILT-IN* ones: FINDDISPLAY (alias -find above) and FINDCREATEDISPLAY (alias -create above.) Most people use these instead of creating their own script. Read the following (especially the BUILT-IN modes sections) to see how to configure these two useful builtin -display WAIT: modes. In the case of -unixpw (and -unixpw_nis only if x11vnc is running as root), then the cmd= command is run as the user who just authenticated via the login and password prompt. In the case of -unixpw_cmd, the commands will also be run as the logged-in user, as long as the user-supplied helper program supports RFB_UNIXPW_CMD_RUN (see the -unixpw_cmd option.) Also in the case of -unixpw, the user logging in can place a colon at the end of her username and supply a few options: scale=, scale_cursor= (or sc=), solid (or so), id=, clear_mods (or cm), clear_keys (or ck), clear_all (or ca), repeat, speeds= (or sp=), readtimeout= (or rd=), viewonly (or vo), nodisplay= (or nd=), rotate= (or ro=), or noncache (or nc), all separated by commas if there is more than one. After the user logs in successfully, these options will be applied to the VNC screen. For example, login: fred:scale=3/4,sc=1,repeat Password: ... login: runge:sp=modem,rd=120,solid for convenience m/n implies scale= e.g. fred:3/4 If you type and enter your password incorrectly, to retrieve your long "login:" line press the Up arrow once (before typing anything else). Most of these colon options only apply to the builtin FINDDISPLAY and FINDCREATEDISPLAY modes, but note that they are passed to the extrenal command in the environment as well and so could be used. In the login panel, press F1 to get a list of the available options that you can add after the username. Another option is "geom=WxH" or "geom=WxHxD" (or ge=). This only has an effect in FINDCREATEDISPLAY mode when a virtual X server such as Xvfb is going to be created. It sets the width and height of the new display, and optionally the color depth as well. You can also supply "gnome", "kde", "twm", "fvwm", "mwm", "dtwm", "wmaker", "xfce", "lxde", "enlightenment", "Xsession", or "failsafe" (same as "xterm") to have the created display use that mode for the user session. Specify "tag=..." to set the unique FD_TAG desktop session tag described below. Note: this option will be ignored if the FD_TAG env. var. is already set or if the viewer-side supplied value is not completely composed of alphanumeric or '_' or '-' characters. User preferences file: Instead of having the user type in geom=WxH,... etc. every time he logs in to find or create his X session, if you set FD_USERPREFS to a string that does not contain the "/" character, then the user's home directory is prepended to that string and if the file exists its first line is read and appended to any options he supplied at the login: prompt. For example -env FD_USERPREFS=.x11vnc_create and the user put "geom=1600x1200" in his ~/.x11vnc_create file. To disable the option setting set the environment variable X11VNC_NO_UNIXPW_OPTS=1 before starting x11vnc. To set any other options, the user can use the gui (x11vnc -gui connect) or the remote control method (x11vnc -R opt:val) during his VNC session. So we see the combination of -display WAIT:cmd=... and -unixpw allows automatic pairing of an unix authenticated VNC user with his desktop. This could be very useful on SunRays and also any system where multiple users share a given machine. The user does not need to remember special ports or passwords set up for his desktop and VNC. A nice way to use WAIT:cmd=... is out of inetd(8) (it automatically forks a new x11vnc for each user). You can have the x11vnc inetd spawned process run as, say, root or nobody. When run as root (for either inetd or display manager), you can also supply the option "-users unixpw=" to have the x11vnc process switch to the user as well. Note: there will be a 2nd SSL helper process that will not switch, but it is only encoding and decoding the encrypted stream at that point. BUILT-IN modes: -- Automatic Finding of User X Sessions -- As a special case, WAIT:cmd=FINDDISPLAY will run a script that works on most Unixes to determine a user's DISPLAY variable and xauthority data (see who(1)). NOTE: The option "-find" is an alias for this mode. To have this default script printed to stdout (e.g. for customization) run with WAIT:cmd=FINDDISPLAY-print To have the script run to print what display it would find use "-finddpy" or WAIT:cmd=FINDDISPLAY-run The standard script runs xdpyinfo(1) run on potential displays. If your X server(s) have a login greeter that exclusively grabs the Xserver, then xdpyinfo blocks forever and this mode will not work. See www.karlrunge.com/x11vnc/faq.html#faq-display-manager for how to disable this for dtgreet on Solaris and possibly for other greeters. In -find/cmd=FINDDISPLAY mode, if you set FD_XDM=1, e.g. 'x11vnc -env FD_XDM=1 -find ...' and x11vnc is running as root (e.g. inetd) then it will try to find the XAUTHORITY file of a running XDM/GDM/KDM login greeter (i.e. no user has logged into an X session yet.) As another special case, WAIT:cmd=HTTPONCE will allow x11vnc to service one http request and then exit. This is usually done in -inetd mode to run on, say, port 5800 and allow the Java vncviewer to be downloaded by client web browsers. For example: 5815 stream tcp nowait root /usr/sbin/tcpd /.../x11vnc \ -inetd -q -http_ssl -prog /.../x11vnc \ -display WAIT:cmd=HTTPONCE Where /.../x11vnc is the full path to x11vnc. It is used in the Apache SSL-portal example (see FAQ). In this mode you can set X11VNC_SKIP_DISPLAY to a comma separated list of displays (e.g. ":0,:1") to ignore in the finding process. The ":" is optional. Ranges n-m e.g. 0-20 can also be supplied. This string can also be set by the connecting user via "nd=" using "+" instead of "," If "nd=all" or you set X11VNC_SKIP_DISPLAY=all then all display finding fails as if you set X11VNC_FINDDISPLAY_ALWAYS_FAILS=1 (below.) On some systems lsof(1) can be very slow. Set the env. var. FIND_DISPLAY_NO_LSOF=1 to skip using lsof to try to find the Linux VT the X server is running on. set FIND_DISPLAY_NO_VT_FIND=1 to avoid looking at all. -- Automatic Creation of User X Sessions -- An interesting option is WAIT:cmd=FINDCREATEDISPLAY that is like FINDDISPLAY in that is uses the same method to find an existing display. However, if it does not find one it will try to *start* up an X server session for the user. This is the only time x11vnc tries to actually start up an X server. NOTE: The option "-create" is an alias for this mode. It will start looking for an open display number at :20 Override via X11VNC_CREATE_STARTING_DISPLAY_NUMBER=n By default 80 X displays are allowed (i.e. going to :99) Override via X11VNC_CREATE_MAX_DISPLAYS=n For its heuristics, the create display script sets LC_ALL=C so that command output is uniform. By default it will try to restore LC_ALL right before starting the user session. However, if you don't mind it keeping LC_ALL=C set the env. var.: X11VNC_CREATE_LC_ALL_C_OK=1 By default FINDCREATEDISPLAY will try Xvfb and then Xdummy: The Xdummy wrapper is part of the x11vnc source code (x11vnc/misc/Xdummy) It should be available in PATH and have run "Xdummy -install" once to create the shared library. Xdummy only works on Linux. As of 12/2009 it no longer needs to be run as root, and the default is to not run as root. In some circumstances permissions may require running it as root, in these cases specify FD_XDUMMY_RUN_AS_ROOT=1, this is the same as supplying -root to the Xdummy cmdline. Xvfb is available on most platforms and does not require root. An advantage of Xdummy over Xvfb is that Xdummy supports RANDR dynamic screen resizing. When x11vnc exits (i.e. user disconnects) the X server session stays running in the background. The FINDDISPLAY will find it directly next time. The user must exit the X session in the usual way for it to terminate (or kill the X server process if all else fails). To troubleshoot the FINDCREATEDISPLAY mechanism, set the following env. var. to an output log file, e.g -env CREATE_DISPLAY_OUTPUT=/tmp/mydebug.txt So this is a somewhat odd mode for x11vnc in that it will start up and poll virtual X servers! This can be used from, say, inetd(8) to provide a means of definitely getting a desktop (either real or virtual) on the machine. E.g. a desktop service: 5900 stream tcp nowait root /usr/sbin/tcpd /.../x11vnc -inetd -q -http -ssl SAVE -unixpw -users unixpw=\ -passwd secret -prog /.../x11vnc \ -display WAIT:cmd=FINDCREATEDISPLAY Where /.../x11vnc is the full path to x11vnc. See the -svc/-service option alias above. If for some reason you do not want x11vnc to ever try to find an existing display set the env. var X11VNC_FINDDISPLAY_ALWAYS_FAILS=1 (also -env ...) This is the same as setting X11VNC_SKIP_DISPLAY=all or supplying "nd=all" after "username:" Use WAIT:cmd=FINDCREATEDISPLAY-print to print out the script that is used for this. You can specify the preferred X server order via e.g., WAIT:cmd=FINDCREATEDISPLAY-Xdummy,Xvfb,X and/or leave out ones you do not want. The the case "X" means try to start up a real, hardware X server using xinit(1) or startx(1). If there is already an X server running the X case may only work on Linux (see startx(1)). "Xvnc" will start up a VNC X server (real- or tight-vnc, e.g. use if Xvfb is not available). "Xsrv" will start up the server program in the variable "FD_XSRV" if it is non-empty. You can make this be a wrapper script if you like (it must handle :N, -geometry, and -depth and other X server options). You can set the environment variable FD_GEOM (or X11VNC_CREATE_GEOM) to WxH or WxHxD to set the width and height and optionally the color depth of the created display. You can also set FD_SESS to be the session (short name of the windowmanager: kde, gnome, twm, failsafe, etc.). FD_OPTS contains extra options to pass to the X server. You can also set FD_PROG to be the full path to the session/windowmanager program. More FD tricks: FD_CUPS=port or FD_CUPS=host:port will set the cups printing environment. Similarly for FD_ESD=port or FD_ESD=host:port for esddsp sound redirection. Set FD_EXTRA to a command to be run a few seconds after the X server starts up. Set FD_TAG to be a unique name for the session, it is set as an X property, that makes FINDDISPLAY only find sessions with that tag value. Set FD_XDMCP_IF to the network interface that the display manager is running on; default is 'localhost' but you may need to set it to '::1' on some IPv6 only systems or misconfigured display managers. If you want the FINDCREATEDISPLAY session to contact an XDMCP login manager (xdm/gdm/kdm) on the same machine, then use "Xvfb.xdmcp" instead of "Xvfb", etc. The user will have to supply his username and password one more time (but he gets to select his desktop type so that can be useful). For this to work, you will need to enable localhost XDMCP (udp port 177) for the display manager. This seems to be: for gdm in gdm.conf: Enable=true in section [xdmcp] for kdm in kdmrc: Enable=true in section [Xdmcp] for xdm in xdm-config: DisplayManager.requestPort: 177 See the shorthand options above "-svc", "-xdmsvc" and "-sshxdmsvc" that specify the above options for some useful cases. If you set the env. var WAITBG=1 x11vnc will go into the background once listening in wait mode. Another special mode is FINDCREATEDISPLAY-Xvnc.redirect, (or FINDDISPLAY-Xvnc.redirect). In this case it will start up Xvnc as above if needed, but instead of polling it in its normal way, it simply does a socket redirection of the connected VNC viewer to the Xvnc. So in Xvnc.redirect x11vnc does no VNC but merely transfers the data back and forth. This should be faster then x11vnc's polling method, but not as fast as connecting directly to the Xvnc with the VNC Viewer. The idea here is to take advantage of x11vnc's display finding/creating scheme, SSL, and perhaps a few others. Most of x11vnc's options do not apply in this mode. Xvnc.redirect should also work for the vnc.so X server module for the h/w display however it will work only for finding the display and the user must already be logged into the X console. -vencrypt mode The VeNCrypt extension to the VNC protocol allows encrypted SSL/TLS connections. If the -ssl mode is enabled, then VeNCrypt is enabled as well BY DEFAULT (they both use a SSL/TLS tunnel, only the protocol handshake is a little different.) To control when and how VeNCrypt is used, specify the mode string. If mode is "never", then VeNCrypt is not used. If mode is "support" (the default) then VeNCrypt is supported. If mode is "only", then the similar and older ANONTLS protocol is not simultaneously supported. x11vnc's normal SSL mode (vncs://) will be supported under -ssl unless you set mode to "force". If mode is prefixed with "nodh:", then Diffie Hellman anonymous key exchange is disabled. If mode is prefixed with "nox509:", then X509 key exchange is disabled. To disable all Anonymous Diffie-Hellman access (susceptible to Man-In-The-Middle attack) you will need to supply "-vencrypt nodh:support -anontls never" or "-vencrypt nodh:only" If mode is prefixed with "newdh:", then new Diffie Hellman parameters are generated for each connection (this can be time consuming: 1-60 secs; see -dhparams below for a faster way) rather than using the fixed values in the program. Using fixed, publicly known values is not known to be a security problem. This setting applies to ANONTLS as well. Long example: -vencrypt newdh:nox509:support Also, if mode is prefixed with "plain:", then if -unixpw mode is active the VeNCrypt "*Plain" username+passwd method is enabled for Unix logins. Otherwise in -unixpw mode the normal login panel is provided. You *MUST* supply the -ssl option for VeNCrypt to be active. The -vencrypt option only fine-tunes its operation. -anontls mode The ANONTLS extension to the VNC protocol allows encrypted SSL/TLS connections. If the -ssl mode is enabled, then ANONTLS is enabled as well BY DEFAULT (they both use a SSL/TLS tunnel, only the protocol handshake is a little different.) ANONTLS is an older SSL/TLS mode introduced by vino. It is referred to as 'TLS' for its registered VNC security-type name, but we use the more descriptive 'ANONTLS' here because it provides only Anonymous Diffie-Hellman encrypted connections, and hence no possibility for certificate authentication. To control when and how ANONTLS is used, specify the mode string. If mode is "never", then ANONTLS is not used. If mode is "support" (the default) then ANONTLS is supported. If mode is "only", then the similar VeNCrypt protocol is not simultaneously supported. x11vnc's normal SSL mode (vncs://) will be supported under -ssl unless you set mode to "force". If mode is prefixed with "newdh:", then new Diffie Hellman parameters are generated for each connection (this can be time consuming: 1-60 secs; see -dhparams below for a faster way) rather than using the fixed values in the program. Using fixed, publicly known values is not known to be a security problem. This setting applies to VeNCrypt as well. See the description of "plain:" under -vencrypt. Long example: -anontls newdh:plain:support You *MUST* supply the -ssl option for ANONTLS to be active. The -anontls option only fine-tunes its operation. -sslonly Same as: "-vencrypt never -anontls never" i.e. it disables the VeNCrypt and ANONTLS encryption methods and only allows standard SSL tunneling. You must also supply the -ssl ... option (see below.) -dhparams file For some operations a set of Diffie Hellman parameters (prime and generator) is needed. If so, use the parameters in "file". In particular, the VeNCrypt and ANONTLS anonymous DH mode need them. By default a fixed set is used. If you do not want to do that you can specify "newdh:" to the -vencrypt and -anontls options to generate a new set each session. If that is too slow for you, use -dhparams file to a set you created manually via "openssl dhparam -out file 1024" -nossl Disable the -ssl option (see below). Since -ssl is off by default -nossl would only be used on the commandline to unset any *earlier* -ssl option (or -svc...) -ssl [pem] Use the openssl library (www.openssl.org) to provide a built-in encrypted SSL/TLS tunnel between VNC viewers and x11vnc. This requires libssl support to be compiled into x11vnc at build time. If x11vnc is not built with libssl support it will exit immediately when -ssl is prescribed. See the -stunnel option below for an alternative. The VNC Viewer-side needs to support SSL/TLS as well. See this URL and also the discussion below for ideas on how to enable SSL support for the viewer: http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-tun nel-viewers . x11vnc provides an SSL enabled Java viewer applet in the classes/ssl directory (-http or -httpdir options.) The SSVNC viewer package supports SSL tunnels too. If the VNC Viewer supports VeNCrypt or ANONTLS (vino's encryption mode) they are also supported by the -ssl mode (see the -vencrypt and -anontls options for more info; use -sslonly to disable both of them.) Use "-ssl /path/to/mycert.pem" to specify an SSL certificate file in PEM format to use to identify and provide a key for this server. See openssl(1) for more info about PEMs and the -sslGenCert and "-ssl SAVE" options below for how to create them. The connecting VNC viewer SSL tunnel can (at its option) authenticate this server if it has the public key part of the certificate (or a common certificate authority, CA, is a more sophisticated way to verify this server's cert, see -sslGenCA below). This authentication is done to prevent Man-In-The-Middle attacks. Otherwise, if the VNC viewer simply accepts this server's key WITHOUT verification, the traffic is protected from passive sniffing on the network, but *NOT* from Man-In-The-Middle attacks. There are hacker tools like dsniff/webmitm and cain that implement SSL Man-In-The-Middle attacks. If [pem] is empty or the string "SAVE" then the openssl(1) command must be available to generate the certificate the first time. A self-signed certificate is generated (see -sslGenCA and -sslGenCert for use of a Certificate Authority.) It will be saved to the file ~/.vnc/certs/server.pem. On subsequent calls if that file already exists it will be used directly. Use "SAVE_NOPROMPT" to avoid being prompted to protect the generated key with a passphrase. However in -inetd and -bg modes there will be no prompting for a passphrase in either case. If [pem] is "SAVE_PROMPT" the server.pem certificate will be created based on your answers to its prompts for all info such as OrganizationalName, CommonName, etc. Use "SAVE-" and "SAVE_PROMPT-" to refer to the file ~/.vnc/certs/server-.pem instead (it will be generated if it does not already exist). E.g. "SAVE-charlie" will store to the file ~/.vnc/certs/server-charlie.pem Examples: x11vnc -ssl SAVE -display :0 ... x11vnc -ssl SAVE-someother -display :0 ... If [pem] is "TMP" and the openssl(1) utility command exists in PATH, then a temporary, self-signed certificate will be generated for this session. If openssl(1) cannot be used to generate a temporary certificate x11vnc exits immediately. The temporary cert will be discarded when x11vnc exits. If successful in using openssl(1) to generate a temporary certificate in "SAVE" or "TMP" creation modes, the public part of it will be displayed to stderr (e.g. one could copy it to the client-side to provide authentication of the server to VNC viewers.) NOTE: In "TMP" mode, unless you safely copy the public part of the temporary Cert to the viewer for authenticate *every time* (unlikely...), then only passive sniffing attacks are prevented and you are still open to Man-In-The-Middle attacks. This is why the default "SAVE" mode is preferred (and more sophisticated CA mode too). Only with saved keys AND the VNC viewer authenticating them (via the public certificate), are Man-In-The-Middle attacks prevented. If [pem] is "ANON" then the Diffie-Hellman anonymous key exchange method is used. In this mode there are *no* SSL certificates and so it is not possible to authenticate either the VNC server or VNC client. Thus only passive network sniffing attacks are avoided: the "ANON" method is susceptible to Man-In-The-Middle attacks. "ANON" is not recommended; instead use a SSL PEM you created or the default "SAVE" method. See -ssldir below to use a directory besides the default ~/.vnc/certs If your x11vnc binary was not compiled with OpenSSL library support, use of the -ssl option will induce an immediate failure and exit. For such binaries, consider using the -stunnel option for SSL encrypted connections. Misc Info: In temporary cert creation mode "TMP", set the env. var. X11VNC_SHOW_TMP_PEM=1 to have x11vnc print out the entire certificate, including the PRIVATE KEY part, to stderr. There are better ways to get/save this info. See "SAVE" above and "-sslGenCert" below. -ssltimeout n Set SSL read timeout to n seconds. In some situations (i.e. an iconified viewer in Windows) the viewer stops talking and the connection is dropped after the default timeout (25s for about the first minute, 43200s later). Set to zero to poll forever. Set to a negative value to use the builtin setting. Note that this value does NOT apply to the *initial* ssl init connection. The default timeout for that is 20sec. Use -env SSL_INIT_TIMEOUT=n to modify it. -sslnofail Exit at the first SSL connection failure. Useful when scripting SSL connections (e.g. x11vnc is started via ssh) and you do not want x11vnc waiting around for more connections, tying up ports, etc. -ssldir dir Use "dir" as an alternate ssl certificate and key management toplevel directory. The default is ~/.vnc/certs This directory is used to store server and other certificates and keys and also other materials. E.g. in the simplest case, "-ssl SAVE" will store the x11vnc server cert in dir/server.pem Use of alternate directories via -ssldir allows you to manage multiple VNC Certificate Authority (CA) keys. Another use is if ~/.vnc/cert is on an NFS share you might want your certificates and keys to be on a local filesystem to prevent network snooping (for example -ssldir /var/lib/x11vnc-certs). -ssldir affects nearly all of the other -ssl* options, e.g. -ssl SAVE, -sslGenCert, etc.. -sslverify path For either of the -ssl or -stunnel modes, use "path" to provide certificates to authenticate incoming VNC *Client* connections (normally only the server is authenticated in SSL.) This can be used as a method to replace standard password authentication of clients. If "path" is a directory it contains the client (or CA) certificates in separate files. If path is a file, it contains one or more certificates. See special tokens below. These correspond to the "CApath = dir" and "CAfile = file" stunnel options. See the stunnel(8) manpage for details. Examples: x11vnc -ssl -sslverify ~/my.crt x11vnc -ssl -sslverify ~/my_pem_dir/ Note that if path is a directory, it must contain the certs in separate files named like .0, where the value of is found by running the command "openssl x509 -hash -noout -in file.crt". Evidently one uses .1 if there is a collision... The the key-management utility "-sslCertInfo HASHON" and "-sslCertInfo HASHOFF" will create/delete these hashes for you automatically (via symlink) in the HASH subdirs it manages. Then you can point -sslverify to the HASH subdir. Special tokens: in -ssl mode, if "path" is not a file or a directory, it is taken as a comma separated list of tokens that are interpreted as follows: If a token is "CA" that means load the CA/cacert.pem file from the ssl directory. If a token is "clients" then all the files clients/*.crt in the ssl directory are loaded. Otherwise the file clients/token.crt is attempted to be loaded. As a kludge, use a token like ../server-foo to load a server cert if you find that necessary. Use -ssldir to use a directory different from the ~/.vnc/certs default. Note that if the "CA" cert is loaded you do not need to load any of the certs that have been signed by it. You will need to load any additional self-signed certs however. Examples: x11vnc -ssl -sslverify CA x11vnc -ssl -sslverify self:fred,self:jim x11vnc -ssl -sslverify CA,clients Usually "-sslverify CA" is the most effective. See the -sslGenCA and -sslGenCert options below for how to set up and manage the CA framework. NOTE: the following utilities, -sslGenCA, -sslGenCert, -sslEncKey, -sslCertInfo, and -sslCRL are provided for completeness, but for casual usage they are overkill. They provide VNC Certificate Authority (CA) key creation and server / client key generation and signing. So they provide a basic Public Key management framework for VNC-ing with x11vnc. (note that they require openssl(1) be installed on the system) However, the simplest usage mode, "-ssl TMP" (where x11vnc automatically generates its own, self-signed, temporary key and the VNC viewers always accept it, e.g. accepting via a dialog box) is probably safe enough for most scenarios. CA management is not needed. To protect against Man-In-The-Middle attacks the "TMP" mode can be improved by using "-ssl SAVE" (same as "-ssl", i.e. the default) to have x11vnc create a longer term self-signed certificate, and then (safely) copy the corresponding public key cert to the desired client machines (care must be taken the private key part is not stolen; you will be prompted for a passphrase). So keep in mind no CA key creation or management (-sslGenCA and -sslGenCert) is needed for either of the above two common usage modes. One might want to use -sslGenCA and -sslGenCert if you had a large number of VNC client and server workstations. That way the administrator could generate a single CA key with -sslGenCA and distribute its certificate part to all of the workstations. Next, he could create signed VNC server keys (-sslGenCert server ...) for each workstation or user that then x11vnc would use to authenticate itself to any VNC client that has the CA cert. Optionally, the admin could also make it so the VNC clients themselves are authenticated to x11vnc (-sslGenCert client ...) For this -sslverify would be pointed to the CA cert (and/or self-signed certs). x11vnc will be able to use all of these cert and key files. On the VNC client side, they will need to be "imported" somehow. Web browsers have "Manage Certificates" actions as does the Java applet plugin Control Panel. stunnel can also use these files (see the ss_vncviewer example script in the FAQ and SSVNC.) -sslCRL path Set the Certificate Revocation Lists (CRL) to "path". This setting applies for both -ssl and -stunnel modes. If path is a file, the file contains one or more CRLs in PEM format. If path is a directory, it contains hash named files of CRLs in the usual OpenSSL manner. See the OpenSSL and stunnel(8) documentation for more info. This option only applies if -sslverify has been supplied: it checks for revocation along the certificate chain used to verify the VNC client. The -sslCRL setting will be ignored when -sslverify is not specified. Note that if a CRL's expiration date has passed, all SSL connections will fail regardless of if they are related to the subject of the CRL or not. Only rarely will one's x11vnc -ssl infrastructure be so large that this option would be useful (since normally maintaining the contents of the -sslverify file or directory should be enough.) However, when using x11vnc with a Certificate Authority (see -sslGenCA) to authenticate Clients via SSL/TLS, the -sslCRL option can be useful to revoke users' certs whose private SSL keys were lost or stolen (e.g. laptop.) This way a new CA cert+key does not need to be created and new signed client keys generated and distributed to all users. To create a CRL file with revoked certificates the commands 'openssl ca -revoke ...' and 'openssl ca -gencrl ...' are useful. (Run them in ~/.vnc/certs) -sslGenCA [dir] Generate your own Certificate Authority private key, certificate, and other files in directory [dir]. x11vnc then exits. If [dir] is not supplied, a -ssldir setting is used, or otherwise ~/.vnc/certs is used. This command also creates directories where server and client certs and keys will be stored. The openssl(1) program must be installed on the system and available in PATH. After the CA files and directories are created the x11vnc command exits; the VNC server is not run. You will be prompted for information to put into the CA certificate. The info does not have to be accurate just as long as clients accept the cert for VNC connections. You will also need to supply a passphrase of at least 4 characters for the CA private key. Once you have generated the CA you can distribute its certificate part, [dir]/CA/cacert.pem, to other workstations where VNC viewers will be run. One will need to "import" this certificate in the applications, e.g. Web browser, Java applet plugin, stunnel, etc. Next, you can create and sign keys using the CA with the -sslGenCert option below. Examples: x11vnc -sslGenCA x11vnc -sslGenCA ~/myCAdir x11vnc -ssldir ~/myCAdir -sslGenCA (the last two lines are equivalent) -sslGenCert type name Generate a VNC server or client certificate and private key pair signed by the CA created previously with -sslGenCA. The openssl(1) program must be installed on the system and available in PATH. After the Certificate is generated x11vnc exits; the VNC server is not run. The type of key to be generated is the string "type". It is either "server" (i.e. for use by x11vnc) or "client" (for a VNC viewer). Note that typically only "server" is used: the VNC clients authenticate themselves by a non-public-key method (e.g. VNC or unix password). "type" is required. An arbitrary default name you want to associate with the key is supplied by the "name" string. You can change it at the various prompts when creating the key. "name" is optional. If name is left blank for clients keys then "nobody" is used. If left blank for server keys, then the primary server key: "server.pem" is created (this is the saved one referenced by "-ssl SAVE" when the server is started) If "name" begins with the string "self:" then a self-signed certificate is created instead of one signed by your CA key. If "name" begins with the string "req:" then only a key (.key) and a certificate signing *request* (.req) are generated. You can then send the .req file to an external CA (even a professional one, e.g. Thawte) and then combine the .key and the received cert into the .pem file with the same basename. The distinction between "server" and "client" is simply the choice of output filenames and sub-directory. This makes it so the -ssl SAVE-name option can easily pick up the x11vnc PEM file this option generates. And similarly makes it easy for the -sslverify option to pick up your client certs. There is nothing special about the filename or directory location of either the "server" and "client" certs. You can rename the files or move them to wherever you like. Precede this option with -ssldir [dir] to use a directory other than the default ~/.vnc/certs You will need to run -sslGenCA on that directory first before doing any -sslGenCert key creation. Note you cannot recreate a cert with exactly the same distiguished name (DN) as an existing one. To do so, you will need to edit the [dir]/CA/index.txt file to delete the line. Similar to -sslGenCA, you will be prompted to fill in some information that will be recorded in the certificate when it is created. Tip: if you know the fully-qualified hostname other people will be connecting to, you can use that as the CommonName "CN" to avoid some applications (e.g. web browsers and java plugin) complaining that it does not match the hostname. You will also need to supply the CA private key passphrase to unlock the private key created from -sslGenCA. This private key is used to sign the server or client certificate. The "server" certs can be used by x11vnc directly by pointing to them via the -ssl [pem] option. The default file will be ~/.vnc/certs/server.pem. This one would be used by simply typing -ssl SAVE. The pem file contains both the certificate and the private key. server.crt file contains the cert only. The "client" cert + private key file will need to be copied and imported into the VNC viewer side applications (Web browser, Java plugin, stunnel, etc.) Once that is done you can delete the "client" private key file on this machine since it is only needed on the VNC viewer side. The, e.g. ~/.vnc/certs/clients/.pem contains both the cert and private key. The .crt contains the certificate only. NOTE: It is very important to know one should generate new keys with a passphrase. Otherwise if an untrusted user steals the key file he could use it to masquerade as the x11vnc server (or VNC viewer client). You will be prompted whether to encrypt the key with a passphrase or not. It is recommended that you do. One inconvenience to a passphrase is that it must be typed in EVERY time x11vnc or the client app is started up. Examples: x11vnc -sslGenCert server x11vnc -ssl SAVE -display :0 ... and then on viewer using ss_vncviewer stunnel wrapper (see the FAQ): ss_vncviewer -verify ./cacert.crt hostname:0 (this assumes the cacert.crt cert from -sslGenCA was safely copied to the VNC viewer machine where ss_vncviewer is run) Example using a name: x11vnc -sslGenCert server charlie x11vnc -ssl SAVE-charlie -display :0 ... Example for a client certificate (rarely used): x11vnc -sslGenCert client roger scp ~/.vnc/certs/clients/roger.pem somehost:. rm ~/.vnc/certs/clients/roger.pem x11vnc is then started with the option -sslverify ~/.vnc/certs/clients/roger.crt (or simply -sslverify roger), and on the viewer user on somehost could do for example: ss_vncviewer -mycert ./roger.pem hostname:0 If you set the env. var REQ_ARGS='...' it will be passed to openssl req(1). A common use would be REQ_ARGS='-days 1095' to bump up the expiration date (3 years in this case). -sslEncKey pem Utility to encrypt an existing PEM file with a passphrase you supply when prompted. For that key to be used (e.g. by x11vnc) the passphrase must be supplied each time. The "SAVE" notation described under -ssl applies as well. (precede this option with -ssldir [dir] to refer a directory besides the default ~/.vnc/certs) The openssl(1) program must be installed on the system and available in PATH. After the Key file is encrypted the x11vnc command exits; the VNC server is not run. Examples: x11vnc -sslEncKey /path/to/foo.pem x11vnc -sslEncKey SAVE x11vnc -sslEncKey SAVE-charlie -sslCertInfo pem Prints out information about an existing PEM file. In addition the public certificate is also printed. The openssl(1) program must be in PATH. Basically the command "openssl x509 -text" is run on the pem. After the info is printed the x11vnc command exits; the VNC server is not run. The "SAVE" notation described under -ssl applies as well. Using "LIST" will give a list of all certs being managed (in the ~/.vnc/certs dir, use -ssldir to refer to another dir). "ALL" will print out the info for every managed key (this can be very long). Giving a client or server cert shortname will also try a lookup (e.g. -sslCertInfo charlie). Use "LISTL" or "LL" for a long (ls -l style) listing. Using "HASHON" will create subdirs [dir]/HASH and [dir]/HASH with OpenSSL hash filenames (e.g. 0d5fbbf1.0) symlinks pointing up to the corresponding *.crt file. ([dir] is ~/.vnc/certs or one given by -ssldir.) This is a useful way for other OpenSSL applications (e.g. stunnel) to access all of the certs without having to concatenate them. x11vnc will not use them unless you specifically reference them. "HASHOFF" removes these HASH subdirs. The LIST, LISTL, LL, ALL, HASHON, HASHOFF words can also be lowercase, e.g. "list". -sslDelCert pem Prompts you to delete all .crt .pem .key .req files associated with [pem]. x11vnc then exits. "SAVE" and lookups as in -sslCertInfo apply as well. -sslScripts Prints out both the 'genCA' and 'genCert' x11vnc openssl wrapper scripts for you to examine, modify, etc. The scripts are printed to stdout and then the x11vnc program exits. -stunnel [pem] Use the stunnel(8) (stunnel.mirt.net) to provide an encrypted SSL tunnel between viewers and x11vnc. This external tunnel method was implemented prior to the integrated -ssl encryption described above. It still works well and avoids the requirement of linking with the OpenSSL libraries. This mode requires stunnel to be installed on the system and available via PATH (n.b. stunnel is often installed in sbin directories). Version 4.x of stunnel is assumed (but see -stunnel3 below.) [pem] is optional, use "-stunnel /path/to/stunnel.pem" to specify a PEM certificate file to pass to stunnel. See the -ssl option for more info on certificate files. Whether or not your stunnel has its own certificate depends on your stunnel configuration; stunnel often generates one at install time. See your stunnel documentation for details. In any event, if you want to use this certificate you must supply the full path to it as [pem]. Note: the file may only be readable by root. [pem] may also be the special strings "TMP", "SAVE", and "SAVE..." as described in the -ssl option. If [pem] is not supplied, "SAVE" is assumed. Note that the VeNCrypt, ANONTLS, and "ANON" modes are not supported in -stunnel mode. stunnel is started up as a child process of x11vnc and any SSL connections stunnel receives are decrypted and sent to x11vnc over a local socket. The strings "The SSL VNC desktop is ..." and "SSLPORT=..." are printed out at startup to indicate this. The -localhost option is enforced by default to avoid people routing around the SSL channel. Use -env STUNNEL_DISABLE_LOCALHOST=1 to disable this security requirement. Set -env STUNNEL_DEBUG=1 for more debugging printout. Set -env STUNNEL_PROG=xxx to the full path of stunnel program you want to be used (e.g. /usr/bin/stunnel4). Set -env STUNNEL_LISTEN=xxx to the address of the network interface to listen on (the default is to listen on all interfaces), e.g. STUNNEL_LISTEN=192.168.1.100. A simple way to add IPv6 support is STUNNEL_LISTEN=:: Your VNC viewer will also need to be able to connect via SSL. Unfortunately not too many do this. See the information about SSL viewers under the -ssl option. The x11vnc project's SSVNC is an option. Also, in the x11vnc distribution, patched TightVNC and UltraVNC Java applet jar files are provided in the classes/ssl directory that do SSL connections. Enable serving them with the -http, -http_ssl, or -httpdir (see the option descriptions for more info.) Note that for the Java viewer applet usage the "?PORT=xxxx" in the various URLs printed at startup will need to be supplied to the web browser to connect properly. Currently the automatic "single port" HTTPS mode of -ssl is not fully supported in -stunnel mode. However, it can be emulated via: % x11vnc -stunnel -http_ssl -http_oneport ... In general, it is also not too difficult to set up an stunnel or other SSL tunnel on the viewer side. A simple example on Unix using stunnel 3.x is: % stunnel -c -d localhost:5901 -r remotehost:5900 % vncviewer localhost:1 For Windows, stunnel has been ported to it and there are probably other such tools available. See the FAQ and SSVNC for more examples. -stunnel3 [pem] Use version 3.x stunnel command line syntax instead of version 4.x. The -http/-httpdir Java applet serving is currently not available in this mode. -enc cipher:keyfile Use symmetric encryption with cipher "cipher" and secret key data in "keyfile". If keyfile is pw= then "string" is used as the key data. NOTE: It is recommended that you use SSL via the -ssl option instead of this option because SSL is well understood and takes great care to establish unique session keys and is more compatible with other software. Use this option if you do not want to deal with SSL certificates for authentication and do not want to use SSH but want some encryption for your VNC session. Or if you must interface with a symmetric key tunnel that you do not have control over. Note that this mode will NOT work with the UltraVNC DSM plugins because they alter the RFB protocol in addition to tunnelling with the symmetric cipher (an unfortunate choice of implementation...) cipher can be one of: arc4, aesv2, aes-cfb, blowfish, aes256, or 3des. See the OpenSSL documentation for more info. The keysize is 128 bits (except for aes256). Here is one way to make a keyfile with that many bits: dd if=/dev/random of=./my.key bs=16 count=1 you will need to securely share this key with the other side of the VNC connection (See SSVNC for examples). Example: -enc blowfish:./my.key Example: -enc blowfish:pw=swordfish By default 16 bytes of random salt followed by 16 bytes of random initialization vector are sent at the very beginning of the stream. The other side must read these and initialize their cipher with them. These values make the session key unique (without them the security is minimal). Similarly, the other side must send us its random salt and IV with those same lengths. The salt and key data are combined to create a session key using an md5 hash as described in EVP_BytesToKey(3). The exact call is: EVP_BytesToKey(Cipher, EVP_md5(), salt, keydata, len, 1, keystr, NULL); where salt is the random data as described above, and keydata is the shared secret key data. keystr is the resulting session key. The cipher is then seeded with keystr and uses the random initialization vector as its first block. To modify the amount of random salt and initialization vector use cipher@n,m where n is the salt length and m the initialization vector length. E.g. -enc aes-cfb@8,16:./my.key It is not a good idea to set either one to zero, although you may be forced to if the other side of the tunnel is not under your control. To skip the salt and EVP_BytesToKey MD5 entirely (no hashing is done: the keydata is directly inserted into the cipher) specify "-1" for the salt, e.g. -enc blowfish@-1,16:./my.key The message digest can also be changed to something besides the default MD5. Use cipher@md+n,m where "md" can be one of sha, sha1, md5, or ripe. For example: -enc arc4@sha+8,16:./my.key The SSVNC vnc viewer project supplies a symmetric encryption tool named "ultravnc_dsm_helper" that can be used on the viewer side. For example: ssvncviewer exec='ultravnc_dsm_helper arc4 my.key 0 h:p' where h:p is the hostname and port of the x11vnc server. ultravnc_dsm_helper may also be used standalone to provide a symmetric encryption tunnel for any viewer or server (VNC or otherwise.) The cipher (1st arg) is basically the same syntax as we use above. Also see the 'Non-Ultra DSM' SSVNC option for the 'UltraVNC DSM Encryption Plugin' advanced option. For both ways of using the viewer, you can specify the salt,ivec sizes (in GUI or, e.g. arc4@8,16). -https [port] Use a special, separate HTTPS port (-ssl and -stunnel modes only) for HTTPS Java viewer applet downloading. I.e. not 5900 and not 5800 (the defaults.) BACKGROUND: In -ssl mode, it turns out you can use the single VNC port (e.g. 5900) for both VNC and HTTPS connections. (HTTPS is used to retrieve a SSL-aware VncViewer.jar applet that is provided with x11vnc). Since both use SSL the implementation was extended to detect if HTTP traffic (i.e. GET) is taking place and handle it accordingly. The URL would be, e.g.: https://mymachine.org:5900/ This is convenient for firewalls, etc, because only one port needs to be allowed in. However, this heuristic adds a few seconds delay to each connection and can be unreliable (especially if the user takes much time to ponder the Certificate dialogs in his browser, Java VM, or VNC Viewer applet. That's right 3 separate "Are you sure you want to connect?" dialogs!) END OF BACKGROUND. USAGE: So use the -https option to provide a separate, more reliable HTTPS port that x11vnc will listen on. If [port] is not provided (or is 0), one is autoselected. The URL to use is printed out at startup. The SSL Java applet directory is specified via the -httpdir option. If not supplied, -https will try to guess the directory as though the -http option was supplied. -httpsredir [port] In -ssl mode with the Java applet retrieved via HTTPS, when the HTML file containing applet parameters ('index.vnc' or 'proxy.vnc') is sent do NOT set the applet PORT parameter to the actual VNC port but set it to "port" instead. If "port" is not supplied, then the port number is guessed from the Host: HTTP header. This is useful when an incoming TCP connection redirection is performed by a router/gateway/firewall from one port to an internal machine where x11vnc is listening on a different port. The Java applet needs to connect to the firewall/router port, not the VNC port on the internal workstation. For example, one could redir from mygateway.com:443 to workstation:5900. This spares the user from having to type in https://mygateway.com/?PORT=443 into their web browser. Note that port 443 is the default https port; other ports must be explicitly indicated, for example: https://mygateway.com:8000/?PORT=8000. To avoid having to include the PORT= in the browser URL, simply supply "-httpsredir" to x11vnc. This option does not work in -stunnel mode. More tricks: set the env var X11VNC_EXTRA_HTTPS_PARAMS to be extra URL parameters to use. This way you do not need to specify extra PARAMS in the index.vnc file. E.g. x11vnc -env X11VNC_EXTRA_HTTPS_PARAMS='?GET=1' ... If you do not want to expose the non-SSL HTTP port to the network (i.e. you just want the single VNC/HTTPS port, e.g. 5900, open for connections) then specify the option -env X11VNC_HTTP_LISTEN_LOCALHOST=1 This way the connection to the LibVNCServer httpd server will only be available on localhost (note that in -ssl mode, HTTPS requests are redirected from SSL to the non-SSL LibVNCServer HTTP server.) -http_oneport For UN-encrypted connections mode (i.e. no -ssl, -stunnel, or -enc options), allow the Java VNC Viewer applet to be downloaded thru the VNC port via HTTP. That is to say, you can use a single port for Java applet viewer connections by using a URL in your web browser like this, for example: http://hostname:5900 The regular, two-port mode, URL http://hostname:5800 will continue to work as well. As mentioned above, this mode will NOT work with the -ssl, -stunnel, or -enc encryption options. Note that is it equivalent to '-enc none' (i.e. it uses the same detection mechanism as for HTTPS, but with no encryption.) HTTPS single-port is on by default in -ssl encrypted mode (and -enc too), so you only need -http_oneport when doing non-SSL encrypted connections. This mode could also be useful for SSH tunnels since it means only one port needs to be redirected. The -httpsredir option may also be useful for this mode when using an SSH tunnel as well as for router port redirections. Note that the -env X11VNC_HTTP_LISTEN_LOCALHOST=1 option described above under -httpsredir applies for the LibVNCServer httpd server in all cases (ssl or not.) -ssh user@host:disp Create a remote listening port on machine "host" via a SSH tunnel using the -R rport:localhost:lport method. lport will be the local x11vnc listening port, so a connection to rport (5900+disp) on "host" will reach x11vnc. E.g. fred@snoopy.com:0 This could be useful if a firewall/router prevents incoming connections to the x11vnc machine, but the ssh machine "host" can be reached by the VNC viewer. "user@" is not needed unless the remote unix username differs from the current one. By default the remote sshd is usually configured to listen only on localhost for rport, so the viewer may need to ssh -L redir to "host" as well (See SSVNC to automate this). The sshd setting GatewayPorts enables listening on all interfaces for rport; viewers can reach it more easily. "disp" is the VNC display for the remote SSH side, e.g. 0 corresponds to port 5900, etc. If disp is greater than 200 the value is used as the port. Use a negative value to force a low port, e.g. host:-80 will use port 80. If ssh-agent is not active, then the ssh password needs to be entered in the terminal where x11vnc is running. By default the remote ssh will issue a 'sleep 300' to wait for the incoming connection for 5 mins. To modify this use user@host:disp+secs. If the remote SSH server is on a non-standard port (i.e. not 22) use user@host:port:disp+secs. Note that the ssh process MAY NOT be killed when x11vnc exits. It tries by looking at ps(1) output. -usepw If no other password method was supplied on the command line, first look for ~/.vnc/passwd and if found use it with -rfbauth; next, look for ~/.vnc/passwdfile and use it with -passwdfile; otherwise, prompt the user for a password to create ~/.vnc/passwd and use it with the -rfbauth option. If none of these succeed x11vnc exits immediately. -storepasswd pass file Store password "pass" as the VNC password in the file "file". Once the password is stored the program exits. Use the password via "-rfbauth file" If called with no arguments, "x11vnc -storepasswd", the user is prompted for a password and it is stored in the file ~/.vnc/passwd. Called with one argument, that will be the file to store the prompted password in. -nopw Disable the big warning message when you use x11vnc without some sort of password. -accept string Run a command (possibly to prompt the user at the X11 display) to decide whether an incoming client should be allowed to connect or not. "string" is an external command run via system(3) or some special cases described below. Be sure to quote "string" if it contains spaces, shell characters, etc. If the external command returns 0 the client is accepted, otherwise the client is rejected. See below for an extension to accept a client view-only. If x11vnc is running as root (say from inetd(8) or from display managers xdm(1), gdm(1), etc), think about the security implications carefully before supplying this option (likewise for the -gone option). Environment: The RFB_CLIENT_IP environment variable will be set to the incoming client IP number and the port in RFB_CLIENT_PORT (or -1 if unavailable). Similarly, RFB_SERVER_IP and RFB_SERVER_PORT (the x11vnc side of the connection), are set to allow identification of the tcp virtual circuit. The x11vnc process id will be in RFB_X11VNC_PID, a client id number in RFB_CLIENT_ID, and the number of other connected clients in RFB_CLIENT_COUNT. RFB_MODE will be "accept". RFB_STATE will be PROTOCOL_VERSION, SECURITY_TYPE, AUTHENTICATION, INITIALISATION, NORMAL, or UNKNOWN indicating up to which state the client has achieved. RFB_LOGIN_VIEWONLY will be 0, 1, or -1 (unknown). RFB_USERNAME, RFB_LOGIN_TIME, and RFB_CURRENT_TIME may also be set. If "string" is "popup" then a builtin popup window is used. The popup will time out after 120 seconds, use "popup:N" to modify the timeout to N seconds (use 0 for no timeout). In the case of "popup" and when the -unixpw option is specified, then a *second* window will be popped up after the user successfully logs in via his UNIX password. This time the user will be identified as UNIX:username@hostname, the "UNIX:" prefix indicates which user the viewer logged as via -unixpw. The first popup is only for whether to allow him to even *try* to login via unix password. If "string" is "xmessage" then an xmessage(1) invocation is used for the command. xmessage must be installed on the machine for this to work. Both "popup" and "xmessage" will present an option for accepting the client "View-Only" (the client can only watch). This option will not be presented if -viewonly has been specified, in which case the entire display is view only. If the user supplied command is prefixed with something like "yes:0,no:*,view:3 mycommand ..." then this associates the numerical command return code with the actions: accept, reject, and accept-view-only, respectively. Use "*" instead of a number to indicate the default action (in case the command returns an unexpected value). E.g. "no:*" is a good choice. Note that x11vnc blocks while the external command or popup is running (other clients may see no updates during this period). So a person sitting a the physical display is needed to respond to an popup prompt. (use a 2nd x11vnc if you lock yourself out). More -accept tricks: use "popupmouse" to only allow mouse clicks in the builtin popup to be recognized. Similarly use "popupkey" to only recognize keystroke responses. These are to help avoid the user accidentally accepting a client by typing or clicking. All 3 of the popup keywords can be followed by +N+M to supply a position for the popup window. The default is to center the popup window. -afteraccept string As -accept, except to run a user supplied command after a client has been accepted and authenticated. RFB_MODE will be set to "afteraccept" and the other RFB_* variables are as in -accept. Unlike -accept, the command return code is not interpreted by x11vnc. Example: -afteraccept 'killall xlock &' -gone string As -accept, except to run a user supplied command when a client goes away (disconnects). RFB_MODE will be set to "gone" and the other RFB_* variables are as in -accept. The "popup" actions apply as well. Unlike -accept, the command return code is not interpreted by x11vnc. Example: -gone 'xlock &' -users list If x11vnc is started as root (say from inetd(8) or from display managers xdm(1), gdm(1), etc), then as soon as possible after connections to the X display are established try to switch to one of the users in the comma separated "list". If x11vnc is not running as root this option is ignored. Why use this option? In general it is not needed since x11vnc is already connected to the X display and can perform its primary functions. The option was added to make some of the *external* utility commands x11vnc occasionally runs work properly. In particular under GNOME and KDE to implement the "-solid color" feature external commands (gconftool-2 and dcop) unfortunately must be run as the user owning the desktop session. Since this option switches userid it also affects the userid used to run the processes for the -accept and -gone options. It also affects the ability to read files for options such as -connect, -allow, and -remap and also the ultra and tight filetransfer feature if enabled. Note that the -connect file is also sometimes written to. So be careful with this option since in some situations its use can decrease security. In general the switch to a user will only take place if the display can still be successfully opened as that user (this is primarily to try to guess the actual owner of the session). Example: "-users fred,wilma,betty". Note that a malicious local user "barney" by quickly using "xhost +" when logging in may possibly get the x11vnc process to switch to user "fred". What happens next? Under display managers it may be a long time before the switch succeeds (i.e. a user logs in). To instead make it switch immediately regardless if the display can be reopened prefix the username with the "+" character. E.g. "-users +bob" or "-users +nobody". The latter (i.e. switching immediately to user "nobody") is the only obvious use of the -users option that increases security. Use the following notation to associate a group with a user: user1.group1,user2.group2,... Note that initgroups(2) will still be called first to try to switch to ALL of a user's groups (primary and additional groups). Only if that fails or it is not available then the single group specified as above (or the user's primary group if not specified) is switched to with setgid(2). Use -env X11VNC_SINGLE_GROUP=1 to prevent trying initgroups(2) and only switch to the single group. This sort of setting is only really needed to make the ultra or tight filetransfer permissions work properly. This format applies to any comma separated list of users, even the special "=" modes described below. In -unixpw mode, if "-users unixpw=" is supplied then after a user authenticates himself via the -unixpw mechanism, x11vnc will try to switch to that user as though "-users +username" had been supplied. If you want to limit which users this will be done for, provide them as a comma separated list after "unixpw=" Groups can also be specified as described above. Similarly, in -ssl mode, if "-users sslpeer=" is supplied then after an SSL client authenticates with his cert (the -sslverify option is required for this) x11vnc will extract a UNIX username from the "emailAddress" field (username@hostname.com) of the "Subject" of the x509 SSL cert and then try to switch to that user as though "-users +username" had been supplied. If you want to limit which users this will be done for, provide them as a comma separated list after "sslpeer=". Set the env. var X11VNC_SSLPEER_CN to use the Common Name (normally a hostname) instead of the Email field. NOTE: for sslpeer= mode the x11vnc administrator must take care that any client certs he adds to -sslverify have the intended UNIX username in the "emailAddress" field of the cert. Otherwise a user may be able to log in as another. This command can be of use in checking: "openssl x509 -text -in file.crt", see the "Subject:" line. Also, along with the normal RFB_* env. vars. (see -accept) passed to external cmd= commands, RFB_SSL_CLIENT_CERT will be set to the client's x509 certificate string. The sslpeer= mode can aid finding X sessions via the FINDDISPLAY and FINDCREATEDISPLAY mechanisms. To immediately switch to a user *before* connections to the X display are made or any files opened use the "=" character: "-users =bob". That user needs to be able to open the X display and any files of course. The special user "guess=" means to examine the utmpx database (see who(1)) looking for a user attached to the display number (from DISPLAY or -display option) and try him/her. To limit the list of guesses, use: "-users guess=bob,betty". Even more sinister is the special user "lurk=" that means to try to guess the DISPLAY from the utmpx login database as well. So it "lurks" waiting for anyone to log into an X session and then connects to it. Specify a list of users after the = to limit which users will be tried. To enable a different searching mode, if the first user in the list is something like ":0" or ":0-2" that indicates a range of DISPLAY numbers that will be tried (regardless of whether they are in the utmpx database) for all users that are logged in. Also see the "-display WAIT:..." functionality. Examples: "-users lurk=" and also "-users lurk=:0-1,bob,mary" Be especially careful using the "guess=" and "lurk=" modes. They are not recommended for use on machines with untrustworthy local users. -noshm Do not use the MIT-SHM extension for the polling. Remote displays can be polled this way: be careful this can use large amounts of network bandwidth. This is also of use if the local machine has a limited number of shm segments and -onetile is not sufficient. -flipbyteorder Sometimes needed if remotely polled host has different endianness. Ignored unless -noshm is set. -onetile Do not use the new copy_tiles() framebuffer mechanism, just use 1 shm tile for polling. Limits shm segments used to 3. To disable any automatic shm reduction set the env. var. X11VNC_NO_LIMIT_SHM. -solid [color] To improve performance, when VNC clients are connected try to change the desktop background to a solid color. The [color] is optional: the default color is "cyan4". For a different one specify the X color (rgb.txt name, e.g. "darkblue" or numerical "#RRGGBB"). Currently this option only works on GNOME, KDE, CDE, XFCE, and classic X (i.e. with the background image on the root window). The "gconftool-2", "dcop" and "xfconf-query" external commands are run for GNOME, KDE, and XFCE respectively. This also works on native MacOSX. (There is no color selection for MacOSX or XFCE.) Other desktops won't work, (send us the corresponding commands if you find them). If x11vnc is running as root (inetd(8) or gdm(1)), the -users option may be needed for GNOME, KDE, XFCE. If x11vnc guesses your desktop incorrectly, you can force it by prefixing color with "gnome:", "kde:", "cde:", "xfce:", or "root:". Update: -solid no longer works on KDE4. This mode works in a limited way on the Mac OS X Console with one color ('kelp') using the screensaver writing to the background. Look in "~/Library/Screen Savers" for VncSolidColor.png to change the color. -blackout string Black out rectangles on the screen. "string" is a comma separated list of WxH+X+Y type geometries for each rectangle. If one of the items on the list is the string "noptr" the mouse pointer will not be allowed to go into a blacked out region. -xinerama If your screen is composed of multiple monitors -noxinerama glued together via XINERAMA, and that screen is not a rectangle this option will try to guess the areas to black out (if your system has libXinerama). default: -xinerama In general, we have noticed on XINERAMA displays you may need to use the "-xwarppointer" option if the mouse pointer misbehaves and it is enabled by default. Use "-noxwarppointer" if you do not want this. -xtrap Use the DEC-XTRAP extension for keystroke and mouse input insertion. For use on legacy systems, e.g. X11R5, running an incomplete or missing XTEST extension. By default DEC-XTRAP will be used if XTEST server grab control is missing, use -xtrap to do the keystroke and mouse insertion via DEC-XTRAP as well. -xrandr [mode] If the display supports the XRANDR (X Resize, Rotate and Reflection) extension, and you expect XRANDR events to occur to the display while x11vnc is running, this options indicates x11vnc should try to respond to them (as opposed to simply crashing by assuming the old screen size). See the xrandr(1) manpage and run 'xrandr -q' for more info. [mode] is optional and described below. Since watching for XRANDR events and trapping errors increases polling overhead, only use this option if XRANDR changes are expected. For example on a rotatable screen PDA or laptop, or using a XRANDR-aware Desktop where you resize often. It is best to be viewing with a vncviewer that supports the NewFBSize encoding, since it knows how to react to screen size changes. Otherwise, LibVNCServer tries to do so something reasonable for viewers that cannot do this (portions of the screen may be clipped, unused, etc). Note: the default now is to check for XRANDR events, but do not trap every X call that may fail due to resize. If a resize event is received, the full -xrandr mode is enabled. To disable even checking for events supply: -noxrandr. "mode" defaults to "resize", which means create a new, resized, framebuffer and hope all viewers can cope with the change. "newfbsize" means first disconnect all viewers that do not support the NewFBSize VNC encoding, and then resize the framebuffer. "exit" means disconnect all viewer clients, and then terminate x11vnc. -rotate string Rotate and/or flip the framebuffer view exported by VNC. This transformation is independent of XRANDR and is done in software in main memory and so may be slower. This mode could be useful on a handheld with portrait or landscape modes that do not correspond to the scanline order of the actual framebuffer. "string" can be: x flip along x-axis y flip along y-axis xy flip along x- and y-axes +90 rotate 90 degrees clockwise -90 rotate 90 degrees counter-clockwise +90x rotate 90 degrees CW, then flip along x +90y rotate 90 degrees CW, then flip along y these give all possible rotations and reflections. Aliases: same as xy: yx, +180, -180, 180 same as -90: +270, 270 same as +90: 90, (ditto for 90x, 90y) Like -scale, this transformation is applied at the very end of any chain of framebuffer transformations and so any options with geometries, e.g. -blackout, -clip, etc. are relative to the original X (or -rawfb) framebuffer, not the final one sent to VNC viewers. If you do not want the cursor shape to be rotated prefix "string" with "nc:", e.g. "nc:+90", "nc:xy", etc. -padgeom WxH Whenever a new vncviewer connects, the framebuffer is replaced with a fake, solid black one of geometry WxH. Shortly afterwards the framebuffer is replaced with the real one. This is intended for use with vncviewers that do not support NewFBSize and one wants to make sure the initial viewer geometry will be big enough to handle all subsequent resizes (e.g. under -xrandr, -remote id:windowid, rescaling, etc.) In -unixpw mode this sets the size of the login screen. Use "once:WxH" it ignore padgeom after the login screen is set up. -o logfile Write stderr messages to file "logfile" instead of to the terminal. Same as "-logfile file". To append to the file use "-oa file" or "-logappend file". If "logfile" contains the string "%VNCDISPLAY" it is expanded to the vnc display (the name may need to be guessed at.) "%HOME" works too. -flag file Write the "PORT=NNNN" (e.g. PORT=5900) string to "file" in addition to stdout. This option could be useful by wrapper script to detect when x11vnc is ready. -rmflag file Remove "file" at exit to signal when x11vnc is done. The file is created at startup if it does not already exist or if "file" is prefixed with "create:". If the file is created, the x11vnc PID is placed in the file. Otherwise the files contents is not changed. Use prefix "nocreate:" to prevent creation. -rc filename Use "filename" instead of $HOME/.x11vncrc for rc file. -norc Do not process any .x11vncrc file for options. -env VAR=VALUE Set the environment variable 'VAR' to value 'VALUE' at x11vnc startup. This is a convenience utility to avoid shell script wrappers, etc. to set the env. var. You may specify as many of these as needed on the command line. -prog /path/to/x11vnc Set the full path to the x11vnc program for cases when it cannot be determined from argv[0] (e.g. tcpd/inetd) -h, -help Print this help text. -?, -opts Only list the x11vnc options. -V, -version Print program version and last modification date. -license Print out license information. Same as -copying and -warranty. -dbg Instead of exiting after cleaning up, run a simple "debug crash shell" when fatal errors are trapped. -q, -quiet Be quiet by printing less informational output to stderr. (use -noquiet to undo an earlier -quiet.) The -quiet option does not eliminate all informational output, it only reduces it. It is ignored in most auxiliary usage modes, e.g. -storepasswd. To eliminate all output use: 2>/dev/null 1>&2, etc. -v, -verbose Print out more information to stderr. -bg Go into the background after screen setup. Messages to stderr are lost unless -o logfile is used. Something like this could be useful in a script: port=`ssh -t $host "x11vnc -display :0 -bg" | grep PORT` port=`echo "$port" | sed -e 's/PORT=//'` port=`expr $port - 5900` vncviewer $host:$port -modtweak Option -modtweak automatically tries to adjust the AltGr -nomodtweak and Shift modifiers for differing language keyboards between client and host. Otherwise, only a single key press/release of a Keycode is simulated (i.e. ignoring the state of the modifiers: this usually works for identical keyboards). Also useful in resolving cases where a Keysym is bound to multiple keys (e.g. "<" + ">" and "," + "<" keys). Default: -modtweak If you are having trouble with with keys and -xkb or -noxkb, and similar things don't help, try -nomodtweak. On some HP-UX systems it is been noted that they have an odd keymapping where a single keycode will have a keysym, e.g. "#", up to three times. You can check via "xmodmap -pk" or the -dk option. The failure is when you try to type "#" it yields "3". If you see this problem try setting the environment variable MODTWEAK_LOWEST=1 to see if it helps. -xkb When in modtweak mode, use the XKEYBOARD extension (if -noxkb the X display supports it) to do the modifier tweaking. This is powerful and should be tried if there are still keymapping problems when using -modtweak by itself. The default is to check whether some common keysyms, e.g. !, @, [, are only accessible via -xkb mode and if so then automatically enable the mode. To disable this automatic detection use -noxkb. When -xkb mode is active you can set these env. vars. They apply only when there is ambiguity as to which key to choose (i.e the mapping is not one-to-one). NOKEYHINTS=1: for up ascii keystrokes do not use score hints saved when the key was pressed down. NOANYDOWN=1: for up keystrokes do not resort to searching through keys that are currently pressed down. KEYSDOWN=N: remember the last N keys press down for tie-breaking when an up keystroke comes in. -capslock When in -modtweak (the default) or -xkb mode, if a keysym in the range A-Z comes in check the X server to see if the Caps_Lock is set. If it is do not artificially press Shift to generate the keysym. This will enable the CapsLock key to behave correctly in some circumstances: namely *both* the VNC viewer machine and the x11vnc X server are in the CapsLock on state. If one side has CapsLock on and the other off and the keyboard is not behaving as you think it should you should correct the CapsLock states (hint: pressing CapsLock inside and outside of the viewer can help toggle them both to the correct state). However, for best results do not use this option, but rather *only* enable CapsLock on the VNC viewer side (i.e. by pressing CapsLock outside of the viewer window, also -skip_lockkeys below). Also try -nomodtweak for a possible workaround. -skip_lockkeys Have x11vnc ignore all Caps_Lock, Shift_Lock, Num_Lock, -noskip_lockkeys Scroll_Lock keysyms received from viewers. The idea is you press Caps_Lock on the VNC Viewer side but that does not change the lock state in the x11vnc-side X server. Nevertheless your capitalized letters come in over the wire and are applied correctly to the x11vnc-side X server. Note this mode probably won't do what you want in -nomodtweak mode. Also, a kludge for KP_n digits is always done in this mode: they are mapped to regular digit keysyms. See also -capslock above. The default is -noskip_lockkeys. -skip_keycodes string Ignore the comma separated list of decimal keycodes. Perhaps these are keycodes not on your keyboard but your X server thinks exist. Currently only applies to -xkb mode. Use this option to help x11vnc in the reverse problem it tries to solve: Keysym -> Keycode(s) when ambiguities exist (more than one Keycode per Keysym). Run 'xmodmap -pk' to see your keymapping. Example: "-skip_keycodes 94,114" -sloppy_keys Experimental option that tries to correct some "sloppy" key behavior. E.g. if at the viewer you press Shift+Key but then release the Shift before Key that could give rise to extra unwanted characters (usually only between keyboards of different languages). Only use this option if you observe problems with some keystrokes. -skip_dups Some VNC viewers send impossible repeated key events, -noskip_dups e.g. key-down, key-down, key-up, key-up all for the same key, or 20 downs in a row for the same modifier key! Setting -skip_dups means to skip these duplicates and just process the first event. Note: some VNC viewers assume they can send down's without the corresponding up's and so you should not set this option for these viewers (symptom: some keys do not autorepeat) Default: -noskip_dups -add_keysyms If a Keysym is received from a VNC viewer and that -noadd_keysyms Keysym does not exist in the X server, then add the Keysym to the X server's keyboard mapping on an unused key. Added Keysyms will be removed periodically and also when x11vnc exits. Default: -add_keysyms -clear_mods At startup and exit clear the modifier keys by sending KeyRelease for each one. The Lock modifiers are skipped. Used to clear the state if the display was accidentally left with any pressed down. -clear_keys As -clear_mods, except try to release ANY pressed key. Note that this option and -clear_mods can interfere with a person typing at the physical keyboard. -clear_all As -clear_keys, except try to release any CapsLock, NumLock, etc. locks as well. -remap string Read Keysym remappings from file named "string". Format is one pair of Keysyms per line (can be name or hex value) separated by a space. If no file named "string" exists, it is instead interpreted as this form: key1-key2,key3-key4,... See header file for a list of Keysym names, or use xev(1). To map a key to a button click, use the fake Keysyms "Button1", ..., etc. E.g: "-remap Super_R-Button2" (useful for pasting on a laptop) I use these if the machine I am viewing from does not have a scrollwheel or I don't like using the one it has: -remap Super_R-Button4,Menu-Button5 -remap KP_Add-Button4,KP_Enter-Button5 the former would be used on a PC, the latter on a MacBook. This way those little used keys can be used to generate bigger hops than the Up and Down arrows provide. One can scroll through text or web pages more quickly this way (especially if x11vnc scroll detection is active.) Use Button44, Button12, etc. for multiple clicks. To disable a keysym (i.e. make it so it will not be injected), remap it to "NoSymbol" or "None". Dead keys: "dead" (or silent, mute) keys are keys that do not produce a character but must be followed by a 2nd keystroke. This is often used for accenting characters, e.g. to put "`" on top of "a" by pressing the dead key and then "a". Note that this interpretation is not part of core X11, it is up to the toolkit or application to decide how to react to the sequence. The X11 names for these keysyms are "dead_grave", "dead_acute", etc. However some VNC viewers send the keysyms "grave", "acute" instead thereby disabling the accenting. To work around this -remap can be used. For example "-remap grave-dead_grave,acute-dead_acute" As a convenience, "-remap DEAD" applies these remaps: g grave-dead_grave a acute-dead_acute c asciicircum-dead_circumflex t asciitilde-dead_tilde m macron-dead_macron b breve-dead_breve D abovedot-dead_abovedot d diaeresis-dead_diaeresis o degree-dead_abovering A doubleacute-dead_doubleacute r caron-dead_caron e cedilla-dead_cedilla If you just want a subset use the first letter label, e.g. "-remap DEAD=ga" to get the first two. Additional remaps may also be supplied via commas, e.g. "-remap DEAD=ga,Super_R-Button2". Finally, "DEAD=missing" means to apply all of the above as long as the left hand member is not already in the X11 keymap. -norepeat Option -norepeat disables X server key auto repeat when -repeat VNC clients are connected and VNC keyboard input is not idle for more than 5 minutes. This works around a repeating keystrokes bug (triggered by long processing delays between key down and key up client events: either from large screen changes or high latency). Default: -norepeat You can set the env. var. X11VNC_IDLE_TIMEOUT to the number of idle seconds you want (5min = 300secs). Note: your VNC viewer side will likely do autorepeating, so this is no loss unless someone is simultaneously at the real X display. Use "-norepeat N" to set how many times norepeat will be reset if something else (e.g. X session manager) undoes it. The default is 2. Use a negative value for unlimited resets. -nofb Ignore video framebuffer: only process keyboard and pointer. Intended for use with Win2VNC and x2vnc dual-monitor setups. -nobell Do not watch for XBell events. (no beeps will be heard) Note: XBell monitoring requires the XKEYBOARD extension. -nosel Do not manage exchange of X selection/cutbuffer between VNC viewers and the X server at all. -noprimary Do not poll the PRIMARY selection for changes to send back to clients. (PRIMARY is still set on received changes, however). -nosetprimary Do not set the PRIMARY selection for changes received from VNC clients. -noclipboard Do not poll the CLIPBOARD selection for changes to send back to clients. (CLIPBOARD is still set on received changes, however). -nosetclipboard Do not set the CLIPBOARD selection for changes received from VNC clients. -seldir string If direction string is "send", only send the selection to viewers, and if it is "recv" only receive it from viewers. To work around apps setting the selection too frequently and messing up the other end. You can actually supply a comma separated list of directions, including "debug" to turn on debugging output. -cursor [mode] Sets how the pointer cursor shape (little icon at the -nocursor mouse pointer) should be handled. The "mode" string is optional and is described below. The default is to show some sort of cursor shape(s). How this is done depends on the VNC viewer and the X server. Use -nocursor to disable cursor shapes completely. Some VNC viewers support the TightVNC CursorPosUpdates and CursorShapeUpdates extensions (cuts down on network traffic by not having to send the cursor image every time the pointer is moved), in which case these extensions are used (see -nocursorshape and -nocursorpos below to disable). For other viewers the cursor shape is written directly to the framebuffer every time the pointer is moved or changed and gets sent along with the other framebuffer updates. In this case, there will be some lag between the vnc viewer pointer and the remote cursor position. If the X display supports retrieving the cursor shape information from the X server, then the default is to use that mode. On Solaris this can be done with the SUN_OVL extension using -overlay (see also the -overlay_nocursor option). A similar overlay scheme is used on IRIX. Xorg (e.g. Linux) and recent Solaris Xsun servers support the XFIXES extension to retrieve the exact cursor shape from the X server. If XFIXES is present it is preferred over Overlay and is used by default (see -noxfixes below). This can be disabled with -nocursor, and also some values of the "mode" option below. Note that under XFIXES cursors with transparency (alpha channel) will usually not be exactly represented and one may find Overlay preferable. See also the -alphacut and -alphafrac options below as fudge factors to try to improve the situation for cursors with transparency for a given theme. The "mode" string can be used to fine-tune the displaying of cursor shapes. It can be used the following ways: "-cursor arrow" - just show the standard arrow nothing more or nothing less. "-cursor none" - same as "-nocursor" "-cursor X" - when the cursor appears to be on the root window, draw the familiar X shape. Some desktops such as GNOME cover up the root window completely, and so this will not work, try "X1", etc, to try to shift the tree depth. On high latency links or slow machines there will be a time lag between expected and the actual cursor shape. "-cursor some" - like "X" but use additional heuristics to try to guess if the window should have a windowmanager-like resizer cursor or a text input I-beam cursor. This is a complete hack, but may be useful in some situations because it provides a little more feedback about the cursor shape. "-cursor most" - try to show as many cursors as possible. Often this will only be the same as "some" unless the display has overlay visuals or XFIXES extensions available. On Solaris and IRIX if XFIXES is not available, -overlay mode will be attempted. -cursor_drag Show cursor shape changes even when the mouse is being dragged with a mouse button down. This is useful if you want to be able to see Drag-and-Drop cursor icons, etc. -arrow n Choose an alternate "arrow" cursor from a set of some common ones. n can be 1 to 6. Default is: 1 Ignored when in XFIXES cursor-grabbing mode. -noxfixes Do not use the XFIXES extension to draw the exact cursor shape even if it is available. Note: To work around a crash in Xorg 1.5 and later some people needed to use -noxfixes. The Xorg crash occurred right after a Display Manager (e.g. GDM) login. Starting with x11vnc 0.9.9 it tries to automatically avoid using XFIXES until it is sure a window manager is running. See the -reopen option for more info and how to use X11VNC_AVOID_WINDOWS=never to disable it. -alphacut n When using the XFIXES extension for the cursor shape, cursors with transparency will not usually be displayed exactly (but opaque ones will). This option sets n as a cutoff for cursors that have transparency ("alpha channel" with values ranging from 0 to 255) Any cursor pixel with alpha value less than n becomes completely transparent. Otherwise the pixel is completely opaque. Default 240 -alphafrac fraction With the threshold in -alphacut some cursors will become almost completely transparent because their alpha values are not high enough. For those cursors adjust the alpha threshold until fraction of the non-zero alpha channel pixels become opaque. Default 0.33 -alpharemove By default, XFIXES cursors pixels with transparency have the alpha factor multiplied into the RGB color values (i.e. that corresponding to blending the cursor with a black background). Specify this option to remove the alpha factor. (useful for light colored semi-transparent cursors). -noalphablend In XFIXES mode do not send cursor alpha channel data to LibVNCServer. The default is to send it. The alphablend effect will only be visible in -nocursorshape mode or for clients with cursorshapeupdates turned off. (However there is a hack for 32bpp with depth 24, it uses the extra 8 bits to store cursor transparency for use with a hacked vncviewer that applies the transparency locally. See the FAQ for more info). -nocursorshape Do not use the TightVNC CursorShapeUpdates extension even if clients support it. See -cursor above. -cursorpos Option -cursorpos enables sending the X cursor position -nocursorpos back to all vnc clients that support the TightVNC CursorPosUpdates extension. Other clients will be able to see the pointer motions. Default: -cursorpos -xwarppointer Move the pointer with XWarpPointer(3X) instead of -noxwarppointer the XTEST extension. Use this as a workaround if the pointer motion behaves incorrectly, e.g. on touchscreens or other non-standard setups. It is also sometimes needed on XINERAMA displays and is enabled by default if XINERAMA is found to be active. To prevent this, use -noxwarppointer. -always_inject Even if there is no displacement (dx = dy = 0) for a VNC mouse event force the pointer to the indicated x,y position anyway. Recent (2009) gui toolkits (gnome) have problems with x11vnc's original mouse input injection method. So x11vnc's mouse input injection method has been modified. To regain the OLD behavior use this option: -always_inject. Then x11vnc will always force positioning the mouse to the x,y position even if that position has not changed since the previous VNC input event. The first place this problem was noticed was in gnome terminal: if you pressed and released mouse button 3, a menu was posted and then its first element 'New Terminal Window' was activated. This was because x11vnc injected the mouse position twice: once on ButtonPress and again on ButtonRelease. The toolkit interpreted the 2nd one as mouse motion even though the mouse hadn't moved. So now by default x11vnc tries to avoid injecting the 2nd one. Note that with the new default x11vnc will be oblivious to applications moving the pointer (warping) or the user at the physical display moving it. So it might, e.g., inject ButtonRelease at the wrong position. If this (or similar scenarios) causes problems in your environment, specify -always_inject for the old method. -buttonmap string String to remap mouse buttons. Format: IJK-LMN, this maps buttons I -> L, etc., e.g. -buttonmap 13-31 Button presses can also be mapped to keystrokes: replace a button digit on the right of the dash with :: or :+: etc. for multiple keys. For example, if the viewing machine has a mouse-wheel (buttons 4 5) but the x11vnc side does not, these will do scrolls: -buttonmap 12345-123:Prior::Next: -buttonmap 12345-123:Up+Up+Up::Down+Down+Down: See header file for a list of Keysyms, or use the xev(1) program. Note: mapping of button clicks to Keysyms may not work if -modtweak or -xkb is needed for the Keysym. If you include a modifier like "Shift_L" the modifier's up/down state is toggled, e.g. to send "The" use :Shift_L+t+Shift_L+h+e: (the 1st one is shift down and the 2nd one is shift up). (note: the initial state of the modifier is ignored and not reset) To include button events use "Button1", ... etc. -buttonmap currently does not work on MacOSX console or in -rawfb mode. Workaround: use -buttonmap IJ...-LM...=n to limit the number of mouse buttons to n, e.g. 123-123=3. This will prevent x11vnc from crashing if the X server reports there are 5 buttons (4/5 scroll wheel), but there are only really 3. -nodragging Do not update the display during mouse dragging events (mouse button held down). Greatly improves response on slow setups, but you lose all visual feedback for drags, text selection, and some menu traversals. It overrides any -pointer_mode setting. -ncache n Client-side caching scheme. Framebuffer memory "n" (an integer) times that of the full display is allocated below the actual framebuffer to cache screen contents for rapid retrieval. So a W x H frambuffer is expanded to a W x (n+1)*H one. Use 0 to disable. The "n" is actually optional, the default is 10. For this and the other -ncache* options below you can abbreviate "-ncache" with "-nc". Also, "-nonc" is the same as "-ncache 0" This is an experimental option, currently implemented in an awkward way in that in the VNC Viewer you can see the pixel cache contents if you scroll down, etc. So you will have to set things up so you can't see that region. If this method is successful, the changes required for clients to do this less awkwardly will be investigated. The SSVNC viewer does a good job at automatically hiding the pixel cache region. Or use SSVNC's -ycrop option to explicitly hide the region. Note that this mode consumes a huge amount of memory, both on the x11vnc server side and on the VNC Viewer side. If n=2 then the amount of RAM used is roughly tripled for both x11vnc and the VNC Viewer. As a rule of thumb, note that 1280x1024 at depth 24 is about 5MB of pixel data. For reasonable response when cycling through 4 to 6 large (e.g. web browser) windows a value n of 6 to 12 is recommended. (that's right: ~10X more memory...) Because of the way window backingstore and saveunders are implemented, n must be even. It will be incremented by 1 if it is not. This mode also works for native MacOS X, but may not be as effective as the X version. This is due to a number of things, one is the drop-shadow compositing that leaves extra areas that need to be repaired (see -ncache_pad). Another is the window iconification animations need to be avoided (see -macicontime). It appears the that the 'Scale' animation mode gives better results than the 'Genie' one. Also, window event detection not as accurate as the X version. -ncache_cr In -ncache mode, try to do copyrect opaque window moves/drags instead of wireframes (this can induce painting errors). The wireframe will still be used when moving a window whose save-unders has not yet been set or has been invalidated. Some VNC Viewers provide better response than others with this option. On Unix, realvnc viewer gives smoother drags than tightvnc viewer. Response may also be choppy if the server side machine is too slow. Sometimes on very slow modem connections, this actually gives an improvement because no pixel data at all (not even the box animation) is sent during the drag. -ncache_no_moveraise In -ncache mode, do not assume that moving a window will cause the window manager to raise it to the top of the stack. The default is to assume it does, and so at the beginning of any wireframe, etc, window moves the window will be pushed to top in the VNC viewer. -ncache_no_dtchange In -ncache mode, do not try to guess when the desktop (viewport) changes to another one (i.e. another workarea). The default is to try to guess and when detected try to make the transistion more smoothly. -ncache_no_rootpixmap In -ncache mode, do not try to snapshot the desktop background to use in guessing or reconstructing window save-unders. -ncache_keep_anims In -ncache mode, do not try to disable window manager animations and other effects (that usually degrade ncache performance or cause painting errors). The default is to try to disable them on KDE (but not GNOME) when VNC clients are connected. For other window managers or desktops that provide animations, effects, compositing, translucency, etc. that interfere with the -ncache method you will have to disable them manually. -ncache_old_wm In -ncache mode, enable some heuristics for old style window managers such as fvwm and twm. -ncache_pad n In -ncache mode, pad each window with n pixels for the caching rectangles. This can be used to try to improve the situation with dropshadows or other compositing (e.g. MacOS X window manager), although it could make things worse. The default is 0 on Unix and 24 on MacOS X. -debug_ncache Turn on debugging and profiling output under -ncache. -wireframe [str] Try to detect window moves or resizes when a mouse -nowireframe button is held down and show a wireframe instead of the full opaque window. This is based completely on heuristics and may not always work: it depends on your window manager and even how you move things around. See -pointer_mode below for discussion of the "bogging down" problem this tries to avoid. Default: -wireframe Shorter aliases: -wf [str] and -nowf The value "str" is optional and, of course, is packed with many tunable parameters for this scheme: Format: shade,linewidth,percent,T+B+L+R,mod,t1+t2+t3+t4 Default: 0xff,2,0,32+8+8+8,all,0.15+0.30+5.0+0.125 If you leave nothing between commas: ",," the default value is used. If you don't specify enough commas, the trailing parameters are set to their defaults. "shade" indicate the "color" for the wireframe, usually a greyscale: 0-255, however for 16 and 32bpp you can specify an rgb.txt X color (e.g. "dodgerblue") or a value > 255 is treated as RGB (e.g. red is 0xff0000). "linewidth" sets the width of the wireframe in pixels. "percent" indicates to not apply the wireframe scheme to windows with area less than this percent of the full screen. "T+B+L+R" indicates four integers for how close in pixels the pointer has to be from the Top, Bottom, Left, or Right edges of the window to consider wireframing. This is a speedup to quickly exclude a window from being wireframed: set them all to zero to not try the speedup (scrolling and selecting text will likely be slower). "mod" specifies if a button down event in the interior of the window with a modifier key (Alt, Shift, etc.) down should indicate a wireframe opportunity. It can be "0" or "none" to skip it, "1" or "all" to apply it to any modifier, or "Shift", "Alt", "Control", "Meta", "Super", or "Hyper" to only apply for that type of modifier key. "t1+t2+t3+t4" specify four floating point times in seconds: t1 is how long to wait for the pointer to move, t2 is how long to wait for the window to start moving or being resized (for some window managers this can be rather long), t3 is how long to keep a wireframe moving before repainting the window. t4 is the minimum time between sending wireframe "animations". If a slow link is detected, these values may be automatically changed to something better for a slow link. -nowireframelocal By default, mouse motion and button presses of a user sitting at the LOCAL display are monitored for wireframing opportunities (so that the changes will be sent efficiently to the VNC clients). Use this option to disable this behavior. -wirecopyrect mode Since the -wireframe mechanism evidently tracks moving -nowirecopyrect windows accurately, a speedup can be obtained by telling the VNC viewers to locally copy the translated window region. This is the VNC CopyRect encoding: the framebuffer update doesn't need to send the actual new image data. Shorter aliases: -wcr [mode] and -nowcr "mode" can be "never" (same as -nowirecopyrect) to never try the copyrect, "top" means only do it if the window was not covered by any other windows, and "always" means to translate the orginally unobscured region (this may look odd as the remaining pieces come in, but helps on a slow link). Default: "always" Note: there can be painting errors or slow response when using -scale so you may want to disable CopyRect in this case "-wirecopyrect never" on the command line or by remote-control. Or you can also use the "-scale xxx:nocr" scale option. -debug_wireframe Turn on debugging info printout for the wireframe heuristics. "-dwf" is an alias. Specify multiple times for more output. -scrollcopyrect mode Like -wirecopyrect, but use heuristics to try to guess -noscrollcopyrect if a window has scrolled its contents (either vertically or horizontally). This requires the RECORD X extension to "snoop" on X applications (currently for certain XCopyArea and XConfigureWindow X protocol requests). Examples: Hitting in a terminal window when the cursor was at the bottom, the text scrolls up one line. Hitting arrow in a web browser window, the web page scrolls up a small amount. Or scrolling with a scrollbar or mouse wheel. Shorter aliases: -scr [mode] and -noscr This scheme will not always detect scrolls, but when it does there is a nice speedup from using the VNC CopyRect encoding (see -wirecopyrect). The speedup is both in reduced network traffic and reduced X framebuffer polling/copying. On the other hand, it may induce undesired transients (e.g. a terminal cursor being scrolled up when it should not be) or other painting errors (window tearing, bunching-up, etc). These are automatically repaired in a short period of time. If this is unacceptable disable the feature with -noscrollcopyrect. Screen clearing kludges: for testing at least, there are some "magic key sequences" (must be done in less than 1 second) to aid repairing painting errors that may be seen when using this mode: 3 Alt_L's in a row: resend whole screen, 4 Alt_L's in a row: reread and resend whole screen, 3 Super_L's in a row: mark whole screen for polling, 4 Super_L's in a row: reset RECORD context, 5 Super_L's in a row: try to push a black screen note: Alt_L is the Left "Alt" key (a single key) Super_L is the Left "Super" key (Windows flag). Both of these are modifier keys, and so should not generate characters when pressed by themselves. Also, your VNC viewer may have its own refresh hot-key or button. "mode" can be "never" (same as -noscrollcopyrect) to never try the copyrect, "keys" means to try it in response to keystrokes only, "mouse" means to try it in response to mouse events only, "always" means to do both. Default: "always" Note: there can be painting errors or slow response when using -scale so you may want to disable CopyRect in this case "-scrollcopyrect never" on the command line or by remote-control. Or you can also use the "-scale xxx:nocr" scale option. -scr_area n Set the minimum area in pixels for a rectangle to be considered for the -scrollcopyrect detection scheme. This is to avoid wasting the effort on small rectangles that would be quickly updated the normal way. E.g. suppose an app updated the position of its skinny scrollbar first and then shifted the large panel it controlled. We want to be sure to skip the small scrollbar and get the large panel. Default: 60000 -scr_skip list Skip scroll detection for applications matching the comma separated list of strings in "list". Some applications implement their scrolling in strange ways where the XCopyArea, etc, also applies to invisible portions of the window: if we CopyRect those areas it looks awful during the scroll and there may be painting errors left after the scroll. Soffice.bin is the worst known offender. Use "##" to denote the start of the application class (e.g. "##XTerm") and "++" to denote the start of the application instance name (e.g. "++xterm"). The string your list is matched against is of the form "^^WM_NAME##Class++Instance" The "xlsclients -la" command will provide this info. If a pattern is prefixed with "KEY:" it only applies to Keystroke generated scrolls (e.g. Up arrow). If it is prefixed with "MOUSE:" it only applies to Mouse induced scrolls (e.g. dragging on a scrollbar). Default: ##Soffice.bin,##StarOffice,##OpenOffice -scr_inc list Opposite of -scr_skip: this list is consulted first and if there is a match the window will be monitored via RECORD for scrolls irrespective of -scr_skip. Use -scr_skip '*' to skip anything that does not match your -scr_inc. Use -scr_inc '*' to include everything. -scr_keys list For keystroke scroll detection, only apply the RECORD heuristics to the comma separated list of keysyms in "list". You may find the RECORD overhead for every one of your keystrokes disrupts typing too much, but you don't want to turn it off completely with "-scr mouse" and -scr_parms does not work or is too confusing. The listed keysyms can be numeric or the keysym names in the header file or from the xev(1) program. Example: "-scr_keys Up,Down,Return". One probably wants to have application specific lists (e.g. for terminals, etc) but that is too icky to think about for now... If "list" begins with the "-" character the list is taken as an exclude list: all keysyms except those list will be considered. The special string "builtin" expands to an internal list of keysyms that are likely to cause scrolls. BTW, by default modifier keys, Shift_L, Control_R, etc, are skipped since they almost never induce scrolling by themselves. -scr_term list Yet another cosmetic kludge. Apply shell/terminal heuristics to applications matching comma separated list (same as for -scr_skip/-scr_inc). For example an annoying transient under scroll detection is if you hit Enter in a terminal shell with full text window, the solid text cursor block will be scrolled up. So for a short time there are two (or more) block cursors on the screen. There are similar scenarios, (e.g. an output line is duplicated). These transients are induced by the approximation of scroll detection (e.g. it detects the scroll, but not the fact that the block cursor was cleared just before the scroll). In nearly all cases these transient errors are repaired when the true X framebuffer is consulted by the normal polling. But they are distracting, so what this option provides is extra "padding" near the bottom of the terminal window: a few extra lines near the bottom will not be scrolled, but rather updated from the actual X framebuffer. This usually reduces the annoying artifacts. Use "none" to disable. Default: "term" -scr_keyrepeat lo-hi If a key is held down (or otherwise repeats rapidly) and this induces a rapid sequence of scrolls (e.g. holding down an Arrow key) the "scrollcopyrect" detection and overhead may not be able to keep up. A time per single scroll estimate is performed and if that estimate predicts a sustainable scrollrate of keys per second between "lo" and "hi" then repeated keys will be DISCARDED to maintain the scrollrate. For example your key autorepeat may be 25 keys/sec, but for a large window or slow link only 8 scrolls per second can be sustained, then roughly 2 out of every 3 repeated keys will be discarded during this period. Default: "4-20" -scr_parms string Set various parameters for the scrollcopyrect mode. The format is similar to that for -wireframe and packed with lots of parameters: Format: T+B+L+R,t1+t2+t3,s1+s2+s3+s4+s5 Default: 0+64+32+32,0.02+0.10+0.9,0.03+0.06+0.5+0.1+5.0 If you leave nothing between commas: ",," the default value is used. If you don't specify enough commas, the trailing parameters are set to their defaults. "T+B+L+R" indicates four integers for how close in pixels the pointer has to be from the Top, Bottom, Left, or Right edges of the window to consider scrollcopyrect. If -wireframe overlaps it takes precedence. This is a speedup to quickly exclude a window from being watched for scrollcopyrect: set them all to zero to not try the speedup (things like selecting text will likely be slower). "t1+t2+t3" specify three floating point times in seconds that apply to scrollcopyrect detection with *Keystroke* input: t1 is how long to wait after a key is pressed for the first scroll, t2 is how long to keep looking after a Keystroke scroll for more scrolls. t3 is how frequently to try to update surrounding scrollbars outside of the scrolling area (0.0 to disable) "s1+s2+s3+s4+s5" specify five floating point times in seconds that apply to scrollcopyrect detection with *Mouse* input: s1 is how long to wait after a mouse button is pressed for the first scroll, s2 is how long to keep waiting for additional scrolls after the first Mouse scroll was detected. s3 is how frequently to try to update surrounding scrollbars outside of the scrolling area (0.0 to disable). s4 is how long to buffer pointer motion (to try to get fewer, bigger mouse scrolls). s5 is the maximum time to spend just updating the scroll window without updating the rest of the screen. -fixscreen string Periodically "repair" the screen based on settings in "string". Hopefully you won't need this option, it is intended for cases when the -scrollcopyrect or -wirecopyrect features leave too many painting errors, but it can be used for any scenario. This option periodically performs costly operations and so interactive response may be reduced when it is on. You can use 3 Alt_L's (the Left "Alt" key) taps in a row (as described under -scrollcopyrect) instead to manually request a screen repaint when it is needed. "string" is a comma separated list of one or more of the following: "V=t", "C=t", "X=t", and "8=t". In these "t" stands for a time in seconds (it is a floating point even though one should usually use values > 2 to avoid wasting resources). V sets how frequently the entire screen should be sent to viewers (it is like the 3 Alt_L's). C sets how long to wait after a CopyRect to repaint the full screen. X sets how frequently to reread the full X11 framebuffer from the X server and push it out to connected viewers. Use of X should be rare, please report a bug if you find you need it. 8= applies only for -8to24 mode: it sets how often the non-default visual regions of the screen (e.g. 8bpp windows) are refreshed. Examples: -fixscreen V=10 -fixscreen C=10 -debug_scroll Turn on debugging info printout for the scroll heuristics. "-ds" is an alias. Specify it multiple times for more output. -noxrecord Disable any use of the RECORD extension. This is currently used by the -scrollcopyrect scheme and to monitor X server grabs. -grab_buster Some of the use of the RECORD extension can leave a -nograb_buster tiny window for XGrabServer deadlock. This is only if the whole-server grabbing application expects mouse or keyboard input before releasing the grab. It is usually a window manager that does this. x11vnc takes care to avoid the problem, but if caught x11vnc will freeze. Without -grab_buster, the only solution is to go the physical display and give it some input to satisfy the grabbing app. Or manually kill and restart the window manager if that is feasible. With -grab_buster, x11vnc will fork a helper thread and if x11vnc appears to be stuck in a grab after a period of time (20-30 sec) then it will inject some user input: button clicks, Escape, mouse motion, etc to try to break the grab. If you experience a lot of grab deadlock, please report a bug. -debug_grabs Turn on debugging info printout with respect to XGrabServer() deadlock for -scrollcopyrect mode. -debug_sel Turn on debugging info printout with respect to PRIMARY, CLIPBOARD, and CUTBUFFER0 selections. -pointer_mode n Various pointer motion update schemes. "-pm" is an alias. The problem is pointer motion can cause rapid changes on the screen: consider the rapid changes when you drag a large window around opaquely. Neither x11vnc's screen polling and vnc compression routines nor the bandwidth to the vncviewers can keep up these rapid screen changes: everything will bog down when dragging or scrolling. So a scheme has to be used to "eat" much of that pointer input before re-polling the screen and sending out framebuffer updates. The mode number "n" can be 0 to 4 and selects one of the schemes desribed below. Note that the -wireframe and -scrollcopyrect modes complement -pointer_mode by detecting (and improving) certain periods of "rapid screen change". n=0: does the same as -nodragging. (all screen polling is suspended if a mouse button is pressed.) n=1: was the original scheme used to about Jan 2004: it basically just skips -input_skip keyboard or pointer events before repolling the screen. n=2 is an improved scheme: by watching the current rate of input events it tries to detect if it should try to "eat" additional pointer events before continuing. n=3 is basically a dynamic -nodragging mode: it detects when the mouse motion has paused and then refreshes the display. n=4 attempts to measures network rates and latency, the video card read rate, and how many tiles have been changed on the screen. From this, it aggressively tries to push screen "frames" when it decides it has enough resources to do so. NOT FINISHED. The default n is 2. Note that modes 2, 3, 4 will skip -input_skip keyboard events (but it will not count pointer events). Also note that these modes are not available in -threads mode which has its own pointer event handling mechanism. To try out the different pointer modes to see which one gives the best response for your usage, it is convenient to use the remote control function, for example "x11vnc -R pm:4" or the tcl/tk gui (Tuning -> pointer_mode -> n). -input_skip n For the pointer handling when non-threaded: try to read n user input events before scanning display. n < 0 means to act as though there is always user input. Default: 10 -allinput Have x11vnc read and process all available client input before proceeding. -input_eagerly Similar to -allinput but use the handleEventsEagerly mechanism built into LibVNCServer. -speeds rd,bw,lat x11vnc tries to estimate some speed parameters that are used to optimize scheduling (e.g. -pointer_mode 4, -wireframe, -scrollcopyrect) and other things. Use the -speeds option to set these manually. The triple "rd,bw,lat" corresponds to video h/w read rate in MB/sec, network bandwidth to clients in KB/sec, and network latency to clients in milliseconds, respectively. If a value is left blank, e.g. "-speeds ,100,15", then the internal scheme is used to estimate the empty value(s). Typical PC video cards have read rates of 5-10 MB/sec. If the framebuffer is in main memory instead of video h/w (e.g. SunRay, shadowfb, dummy driver, Xvfb), the read rate may be much faster. "x11perf -getimage500" can be used to get a lower bound (remember to factor in the bytes per pixel). It is up to you to estimate the network bandwith and latency to clients. For the latency the ping(1) command can be used. For convenience there are some aliases provided, e.g. "-speeds modem". The aliases are: "modem" for 6,4,200; "dsl" for 6,100,50; and "lan" for 6,5000,1 -wmdt string For some features, e.g. -wireframe and -scrollcopyrect, x11vnc has to work around issues for certain window managers or desktops (currently kde and xfce). By default it tries to guess which one, but it can guess incorrectly. Use this option to indicate which wm/dt. "string" can be "gnome", "kde", "cde", "xfce", or "root" (classic X wm). Anything else is interpreted as "root". -debug_pointer Print debugging output for every pointer event. -debug_keyboard Print debugging output for every keyboard event. Same as -dp and -dk, respectively. Use multiple times for more output. -defer time Time in ms to delay sending updates to connected clients (deferUpdateTime) Default: 20 -wait time Time in ms to pause between screen polls. Used to cut down on load. Default: 20 -extra_fbur n Perform extra FrameBufferUpdateRequests checks to try to be in better sync with the client's requests. What this does is perform extra polls of the client socket at critical times (before '-defer' and '-wait' calls.) The default is n=1. Set to a larger number to insert more checks or set to n=0 to disable. A downside of these extra calls is that more mouse input may be processed than desired. -wait_ui factor Factor by which to cut the -wait time if there has been recent user input (pointer or keyboard). Improves response, but increases the load whenever you are moving the mouse or typing. Default: 2.00 -setdefer n When the -wait_ui mechanism cuts down the wait time ms, set the defer time to the same ms value. n=1 to enable, 0 to disable, and -1 to set defer to 0 (no delay). Similarly, 2 and -2 indicate 'urgent_update' mode should be used to push the updates even sooner. Default: 1 -nowait_bog Do not detect if the screen polling is "bogging down" and sleep more. Some activities with no user input can slow things down a lot: consider a large terminal window with a long build running in it continuously streaming text output. By default x11vnc will try to detect this (3 screen polls in a row each longer than 0.25 sec with no user input), and sleep up to 1.5 secs to let things "catch up". Use this option to disable that detection. -slow_fb time Floating point time in seconds to delay all screen polling. For special purpose usage where a low frame rate is acceptable and desirable, but you want the user input processed at the normal rate so you cannot use -wait. -xrefresh time Floating point time in seconds to indicate how often to do the equivalent of xrefresh(1) to force all windows (in the viewable area if -id, -sid, or -clip is used) to repaint themselves. Use this only if applications misbehave by not repainting themselves properly. See also -noxdamage. -nap Monitor activity and if it is low take longer naps -nonap between screen polls to really cut down load when idle. Default: take naps -sb time Time in seconds after NO activity (e.g. screen blank) to really throttle down the screen polls (i.e. sleep for about 1.5 secs). Use 0 to disable. Default: 60 Set the env. var. X11VNC_SB_FACTOR to scale it. -readtimeout n Set LibVNCServer rfbMaxClientWait to n seconds. On slow links that take a long time to paint the first screen LibVNCServer may hit the timeout and drop the connection. Default: 20 seconds. -ping n Send a 1x1 framebuffer update to all clients every n seconds (e.g. to try to keep a network connection alive) -nofbpm If the system supports the FBPM (Frame Buffer Power -fbpm Management) extension (i.e. some Sun systems), then prevent the video h/w from going into a reduced power state when VNC clients are connected. FBPM capable video h/w save energy when the workstation is idle by going into low power states (similar to DPMS for monitors). This interferes with x11vnc's polling of the framebuffer data. "-nofbpm" means prevent FBPM low power states whenever VNC clients are connected, while "-fbpm" means to not monitor the FBPM state at all. See the xset(1) manpage for details. -nofbpm is basically the same as running "xset fbpm force on" periodically. Default: -fbpm -nodpms If the system supports the DPMS (Display Power Management -dpms Signaling) extension, then prevent the monitor from going into a reduced power state when VNC clients are connected. DPMS reduced power monitor states are a good thing and you normally want the power down to take place (usually x11vnc has no problem exporting the display in this state). You probably only want to use "-nodpms" to work around problems with Screen Savers kicking on in DPMS low power states. There is known problem with kdesktop_lock on KDE where the screen saver keeps kicking in every time user input stops for a second or two. Specifying "-nodpms" works around it. "-nodpms" means prevent DPMS low power states whenever VNC clients are connected, while "-dpms" means to not monitor the DPMS state at all. See the xset(1) manpage for details. -nodpms is basically the same as running "xset dpms force on" periodically. Default: -dpms -forcedpms If the system supports the DPMS (Display Power Management Signaling) extension, then try to keep the monitor in a powered off state. This is to prevent nosey people at the physical display from viewing what is on the screen. Be sure to lock the screen before disconnecting. This method is far from bullet proof, e.g. suppose someone attaches a non-DPMS monitor, or loads the machine so that there is a gap of time before x11vnc restores the powered off state? On many machines if he floods it with keyboard and mouse input he can see flashes of what is on the screen before the DPMS off state is reestablished. For this to work securely there would need to be support in the X server to do this exactly rather than approximately with DPMS. -clientdpms As -forcedpms but only when VNC clients are connected. -noserverdpms The UltraVNC ServerInput extension is supported. This allows the VNC viewer to click a button that will cause the server (x11vnc) to try to disable keyboard and mouse input at the physical display and put the monitor in dpms powered off state. Use this option to skip powering off the monitor. -noultraext Disable the following UltraVNC extensions: SingleWindow and ServerInput. The others managed by LibVNCServer (textchat, 1/n scaling, rfbEncodingUltra) are not. -chatwindow Place a local UltraVNC chat window on the X11 display that x11vnc is polling. That way the person on the VNC viewer-side can chat with the person at the physical X11 console. (e.g. helpdesk w/o telephone) For this to work the SSVNC package (version 1.0.21 or later) MUST BE installed on the system where x11vnc runs and the 'ssvnc' command must be available in $PATH. The ssvncviewer is used as a chat window helper. See http://www.karlrunge.com/x11vnc/ssvnc.html This option implies '-rfbversion 3.6' so as to trick UltraVNC viewers, otherwise they assume chat is not available. To specify a different rfbversion, place it after the -chatwindow option on the cmdline. See also the remote control 'chaton' and 'chatoff' actions. These can also be set from the tkx11vnc GUI. -noxdamage Do not use the X DAMAGE extension to detect framebuffer changes even if it is available. Use -xdamage if your default is to have it off. x11vnc's use of the DAMAGE extension: 1) significantly reduces the load when the screen is not changing much, and 2) detects changed areas (small ones by default) more quickly. Currently the DAMAGE extension is overly conservative and often reports large areas (e.g. a whole terminal or browser window) as damaged even though the actual changed region is much smaller (sometimes just a few pixels). So heuristics were introduced to skip large areas and use the damage rectangles only as "hints" for the traditional scanline polling. The following tuning parameters are introduced to adjust this behavior: -xd_area A Set the largest DAMAGE rectangle area "A" (in pixels: width * height) to trust as truly damaged: the rectangle will be copied from the framebuffer (slow) no matter what. Set to zero to trust *all* rectangles. Default: 20000 -xd_mem f Set how long DAMAGE rectangles should be "remembered", "f" is a floating point number and is in units of the scanline repeat cycle time (32 iterations). The default (1.0) should give no painting problems. Increase it if there are problems or decrease it to live on the edge (perhaps useful on a slow machine). -sigpipe string Broken pipe (SIGPIPE) handling. "string" can be "ignore" or "exit". For "ignore" LibVNCServer will handle the abrupt loss of a client and continue, for "exit" x11vnc will cleanup and exit at the 1st broken connection. This option is not really needed since LibVNCServer is doing the correct thing now for quite some time. However, for convenience you can use it to ignore other signals, e.g. "-sigpipe ignore:HUP,INT,TERM" in case that would be useful for some sort of application. You can also put "exit:.." in the list to have x11vnc cleanup on the listed signals. "-sig" is an alias for this option if you don't like the 'pipe'. Example: -sig ignore:INT,TERM,exit:USR1 -threads Whether or not to use the threaded LibVNCServer -nothreads algorithm [rfbRunEventLoop] if libpthread is available. In this mode new threads (one for input and one for output) are created to handle each new client. Default: -nothreads. Thread stability is much improved in version 0.9.8. Multiple clients in threaded mode should be stable for the ZRLE encoding on all platforms. The Tight and Zlib encodings are currently only stable on Linux for multiple clients. Compile with -DTLS=__thread if your OS and compiler and linker support it. For resizes (randr, etc.) set this env. var. to the number of milliseconds to sleep: X11VNC_THREADS_NEW_FB_SLEEP at various places in the do_new_fb() action. This is to let various activities settle. Default is about 500ms. Multiple clients in threaded mode could yield better performance for 'class-room' broadcasting usage; also in -appshare broadcast mode. See also the -reflect option. -fs f If the fraction of changed tiles in a poll is greater than f, the whole screen is updated. Default: 0.75 -gaps n Heuristic to fill in gaps in rows or cols of n or less tiles. Used to improve text paging. Default: 4 -grow n Heuristic to grow islands of changed tiles n or wider by checking the tile near the boundary. Default: 3 -fuzz n Tolerance in pixels to mark a tiles edges as changed. Default: 2 -debug_tiles Print debugging output for tiles, fb updates, etc. -snapfb Instead of polling the X display framebuffer (fb) for changes, periodically copy all of X display fb into main memory and examine that copy for changes. (This setting also applies for non-X -rawfb modes). Under some circumstances this will improve interactive response, or at least make things look smoother, but in others (most!) it will make the response worse. If the video h/w fb is such that reading small tiles is very slow this mode could help. To keep the "framerate" up the screen size x bpp cannot be too large. Note that this mode is very wasteful of memory I/O resources (it makes full screen copies even if nothing changes). It may be of use in video capture-like applications, webcams, or where window tearing is a problem. -rawfb string Instead of polling X, poll the memory object specified in "string". For file polling, to memory map mmap(2) a file use: "map:/path/to/a/file@WxHxB", with framebuffer Width, Height, and Bits per pixel. "mmap:..." is the same. If there is trouble with mmap, use "file:/..." for slower lseek(2) based reading. Use "snap:..." to imply -snapfb mode and the "file:" access (this is for unseekable devices that only provide the fb all at once, e.g. a video camera provides the whole frame). For shared memory segments string is of the form: "shm:N@WxHxB" which specifies a shm key(or a shmid) N and with WxHxB as above. See shmat(1) and ipcs(1) Since shm key can be defined constantly, you should use shm key rather than shmid. Unless you have a special purpose, a mutable shmid may cause problems. If there is a new desktop like Wayland, use "drm:" to access GPU FrameBuffer. If you do not know the GPU path, just use "/dev/dri/card0@WxHxB". If you do not supply a type "map" is assumed if the file exists (see the next paragraphs for some exceptions to this.) If string is "setup:cmd", then the command "cmd" is run and the first line from it is read and used as "string". This allows initializing the device, determining WxHxB, etc. These are often done as root so take care. If the string begins with "video", see the VIDEO4LINUX discussion below where the device may be queried for (and possibly set) the framebuffer parameters. If the string begins with "console", "/dev/fb", "fb", or "vt", see the LINUX CONSOLE discussion below where the framebuffer device is opened and keystrokes (and possibly mouse events) are inserted into the console. If the string begins with "vnc", see the VNC HOST discussion below where the framebuffer is taken as that of another remote VNC server. Optional suffixes are ":R/G/B", "+O", and "#VWxVH" to specify red, green, and blue masks (in hex), offset into the memory object, and virtual width and height. If the masks are not provided x11vnc guesses them based on the bpp (if the colors look wrong, you need to provide the masks.) Another optional suffix is the Bytes Per Line which in some cases is not WxB/8. Specify it as WxHxB-BPL e.g. 800x600x16-2048. This could be a normal width 1024 at 16bpp fb, but only width 800 shows up. The last optional suffix is virtual dimensions VWxVH. Some devices will double buffer the display in the framebuffer, allowing updating contents of display and then "panning" to the buffer via yoffset. x11vnc will map the virutal size specified by the options stead of just WxH, and track yoffset appropriately so remote clients get all updates to the frame buffer. So the full format is: mode:file@WxHxB:R/G/B+O-BPL#VWxVH Examples: -rawfb shm:210337933@800x600x32:ff/ff00/ff0000 -rawfb drm:/dev/dri/card0@800x600x32:ff/ff00/ff0000 -rawfb map:/dev/fb0@1024x768x32 -rawfb map:/dev/fb0@800x480x16#800x960 -rawfb map:/tmp/Xvfb_screen0@640x480x8+3232 -rawfb file:/tmp/my.pnm@250x200x24+37 -rawfb file:/dev/urandom@128x128x8 -rawfb snap:/dev/video0@320x240x24 -24to32 -rawfb video0 -rawfb video -pipeinput VID -rawfb console -rawfb vt2 -rawfb vnc:somehost:0 (see ipcs(1) and fbset(1) for the first two examples) In general all user input is discarded by default (see the -pipeinput option for how to use a helper program to insert). Most of the X11 (screen, keyboard, mouse) options do not make sense and many will cause this mode to crash, so please think twice before setting or changing them in a running x11vnc. If you DO NOT want x11vnc to close the X DISPLAY in rawfb mode, prepend a "+" e.g. +file:/dev/fb0... Keeping the display open enables the default remote-control channel, which could be useful. Alternatively, if you specify -noviewonly, then the mouse and keyboard input are STILL sent to the X display, this usage should be very rare, i.e. doing something strange with /dev/fb0. If the device is not "seekable" (e.g. webcam) try reading it all at once in full snaps via the "snap:" mode (note: this is a resource hog). If you are using file: or map: AND the device needs to be reopened for *every* snapfb snapshot, set the environment variable: SNAPFB_RAWFB_RESET=1 as well. If you want x11vnc to dynamically transform a 24bpp rawfb to 32bpp (note that this will be slower) also supply the -24to32 option. This would be useful for, say, a video camera that delivers the pixel data as 24bpp packed RGB. This is the default under "video" mode if the bpp is 24. Normally the bits per pixel, B, is 8, 16, or 32 (or rarely 24), however there is also some support for B < 8 (e.g. old graphics displays 4 bpp or 1 bpp). In this case you certainly must supply the masks as well: WxHxB:R/G/B. The pixels will be padded out to 8 bpp using depth 8 truecolor. The scheme currently does not work with snap fb (ask if interested.) B=1 monochrome example: file:/dev/urandom@128x128x1:1/1/1 Some other like this are 128x128x2:3/3/3 128x128x4:7/7/7 For B < 8 framebuffers you can also set the env. var RAWFB_CGA=1 to try a CGA mapping for B=4 (e.g. linux vga16fb driver.) Note with low bpp and/or resolution VGA and VGA16 modes on the Linux console one's attempt to export them via x11vnc can often be thwarted due to special color palettes, pixel packings, and even video painting buffering. OTOH, often experimenting with the RGB masks can yield something recognizable. VIDEO4LINUX: on Linux some attempt is made to handle video devices (webcams or TV tuners) automatically. The idea is the WxHxB will be extracted from the device itself. So if you do not supply "@WxHxB... parameters x11vnc will try to determine them. It first tries the v4l API if that support has been compiled in. Otherwise it will run the v4l-info(1) external program if it is available. The simplest examples are "-rawfb video" and "-rawfb video1" which imply the device file /dev/video and /dev/video1, respectively. You can also supply the /dev if you like, e.g. "-rawfb /dev/video0" Since the video capture device framebuffer usually changes continuously (e.g. brightness fluctuations), you may want to use the -wait, -slow_fb, or -defer options to lower the "framerate" to cut down on network VNC traffic. A more sophisticated video device scheme allows initializing the device's settings using: -rawfb video: The prefix could also be, as above, e.g. "video1:" to specify the device file. The v4l API must be available for this to work. Otherwise, you will need to try to initialize the device with an external program, e.g. xawtv, spcaview, and hope they persist when x11vnc re-opens the device. is a comma separated list of key=value pairs. The device's brightness, color, contrast, and hue can be set to percentages, e.g. br=80,co=50,cn=44,hu=60. The device filename can be set too if needed (if it does not start with "video"), e.g. fn=/dev/qcam. The width, height and bpp of the framebuffer can be set via, e.g., w=160,h=120,bpp=16. Related to the bpp above, the pixel format can be set via the fmt=XXX, where XXX can be one of: GREY, HI240, RGB555, RGB565, RGB24, and RGB32 (with bpp 8, 8, 16, 16, 24, and 32 respectively). See http://www.linuxtv.org for more info (V4L api). For TV/rf tuner cards one can set the tuning mode via tun=XXX where XXX can be one of PAL, NTSC, SECAM, or AUTO. One can switch the input channel by the inp=XXX setting, where XXX is the name of the input channel (Television, Composite1, S-Video, etc). Use the name that is in the information about the device that is printed at startup. For input channels with tuners (e.g. Television) one can change which station is selected by the sta=XXX setting. XXX is the station number. Currently only the ntsc-cable-us (US cable) channels are built into x11vnc. See the -freqtab option below to supply one from xawtv. If XXX is greater than 500, then it is interpreted as a raw frequency in KHz. Example: -rawfb video:br=80,w=320,h=240,fmt=RGB32,tun=NTSC,sta=47 one might need to add inp=Television too for the input channel to be TV if the card doesn't come up by default in that one. Note that not all video capture devices will support all of the above settings. See the -pipeinput VID option below for a way to control the settings through the VNC Viewer via keystrokes. As a shortcut, if the string begins "Video.." instead of "video.." then -pipeinput VID is implied. As above, if you specify a "@WxHxB..." after the string they are used verbatim: the device is not queried for the current values. Otherwise the device will be queried. LINUX CONSOLE: The following describes some ways to view and possibly interact with the Linux text/graphics console (i.e. not X11 XFree86/Xorg) Note: If the LibVNCServer LinuxVNC program is on your system you may want to use that instead of the following method because it will be faster and more accurate for the Linux text console and includes mouse support. There is, however, the basic LinuxVNC functionality in x11vnc if you replace "console" with "vt" in the examples below. If the rawfb string begins with "console" the framebuffer device /dev/fb0 is opened and /dev/tty0 is opened too. The latter is used to inject keystrokes (not all are supported, but the basic ones are). You will need to be root to inject keystrokes, but not necessarily to open /dev/fb0. /dev/tty0 refers to the active VT, to indicate one explicitly, use, e.g., "console2" for /dev/tty2, etc. by indicating the specific VT number. For the Linux framebuffer device, /dev/fb0, (fb1, etc) to be enabled the appropriate kernel drivers must be loaded. E.g. vesafb or vga16fb and also by setting the boot parameter vga=0x301 (or 0x314, 0x317, etc.) (The vga=... method is the preferred way; set your machines up that way.) Otherwise there will be a 'No such device' error. You can also load a Linux framebuffer driver specific to your make of video card for more functionality. Once the machine is booted one can often 'modprobe' the fb driver as root to obtain a framebuffer device. If you cannot get /dev/fb0 working on Linux, try using the LinuxVNC emulation mode by "-rawfb vtN" where N = 1, ... 6 is the Linux Virtual Terminal (aka virtual console) you wish to view, e.g. "-rawfb vt2". Unlike /dev/fb mode, it need not be the active Virtual Terminal. Note that this mode can only show text and not graphics. x11vnc polls the text in /dev/vcsaN Set the env. var. RAWFB_VCSA_BW=1 to disable colors in the "vtN" mode (i.e. black and white only.) If you do not prefer the default 16bpp set RAWFB_VCSA_BPP to 8 or 32. If you need to tweak the rawfb parameters by using the 'console_guess' string printed at startup, be sure to indicate the snap: method. uinput: If the Linux version appears to be 2.6 or later and the "uinput" module appears to be present (modprobe uinput), then the uinput method will be used instead of /dev/ttyN. uinput allows insertion of BOTH keystrokes and mouse input and so it preferred when accessing graphical (e.g. QT-embedded) linux console apps. It also provides more accurate keystroke insertion. See -pipeinput UINPUT below for more information on this mode; you will have to use -pipeinput if you want to tweak any UINPUT parameters. You may also want to also use the -nodragging and -cursor none options. Use "console0", etc or -pipeinput CONSOLE to force the /dev/ttyN method. Note you can change the Linux VT remotely using the chvt(1) command to make the one you want be the active one (e.g. 'chvt 3'). Sometimes switching out and back corrects the framebuffer's graphics state. For the "-rawfb vtN" mode there is no need to switch the VT's. To skip input injecting entirely use "consolex" or "vtx". The string "/dev/fb0" (1, etc.) can be used instead of "console". This can be used to specify a different framebuffer device, e.g. /dev/fb1. As a shortcut the "/dev/" can be dropped. If the name is something nonstandard, use "console:/dev/foofb" If you do not want x11vnc to guess the framebuffer's WxHxB and masks automatically (sometimes the kernel gives incorrect information), specify them with a @WxHxB (and optional :R/G/B masks) at the end of the string. Examples: -rawfb console -rawfb /dev/fb0 (same) -rawfb console3 (force /dev/tty3) -rawfb consolex (no keystrokes or mouse) -rawfb console:/dev/nonstd -rawfb console -pipeinput UINPUT:accel=4.0 -rawfb vt3 (/dev/tty3 w/o /dev/fb0) VNC HOST: if the -rawfb string is of the form "vnc:host:N" then the VNC display "N" on the remote VNC server "host" is connected to (i.e. x11vnc acts as a VNC client itself) and that framebuffer is exported. This mode is really only of use if you are trying to improve performance in the case of many (e.g. > 10) simultaneous VNC viewers, and you try a divide and conquer scheme to reduce bandwidth and improve responsiveness. (However, another user found this mode useful to export a demo display through a slow link: then multiple demo viewers connected to the reflecting x11vnc on the fast side of the link, and so avoided all of the demo viewers going through the slow link.) For example, if there will be 64 simultaneous VNC viewers this can lead to a lot of redundant VNC traffic to and from the server host:N, extra CPU usage, and all viewers response can be reduced by having to wait for writes to the slowest client to finish. However, if you set up 8 reflectors/repeaters started with option -rawfb vnc:host:N, then there are only 8 connections to host:N. Each repeater then handles 8 vnc viewer connections thereby spreading the load around. In classroom broadcast usage, try to put the repeaters on different switches. This mode is the same as -reflect host:N. Replace "host:N" by "listen" or "listen:port" for a reverse connection. Overall performance will not be as good as a single direct connection because, among other things, there is an additional level of framebuffer polling and pointer motion can still induce many changes per second that must be propagated. Tip: if the remote VNC is x11vnc doing wireframing, or an X display that does wireframing that gives much better response than opaque window dragging. Consider the -nodragging option if the problem is severe. The env. var. X11VNC_REFLECT_PASSWORD can be set to the password needed to log into the vnc host server, or to "file:path_to_file" to indicate a file containing the password as its first line. To set the pixel format that x11vnc requests as a VNC CLIENT set the env. vars: X11VNC_REFLECT_bitsPerSample X11VNC_REFLECT_samplesPerPixel, and X11VNC_REFLECT_bytesPerPixel; the defaults are 8, 3, 4. 2, 3, 1 would give a low color mode. See the function rfbGetClient() in libvncclient for more info. The VNC HOST mode implies -shared. Use -noshared as a subsequent cmdline option to disable sharing. -freqtab file For use with "-rawfb video" for TV tuner devices to specify station frequencies. Instead of using the built in ntsc-cable-us mapping of station number to frequency, use the data in file. For stations that are not numeric, e.g. SE20, they are placed above the highest numbered station in the order they are found. Example: "-freqtab /usr/X11R6/share/xawtv/europe-west.list" You can make your own freqtab by copying the xawtv format. -pipeinput cmd This option lets you supply an external command in "cmd" that x11vnc will pipe all of the user input events to in a simple format. In -pipeinput mode by default x11vnc will not process any of the user input events. If you prefix "cmd" with "tee:" it will both send them to the pipe command and process them. For a description of the format run "-pipeinput tee:/bin/cat". Another prefix is "reopen" which means to reopen pipe if it exits. Separate multiple prefixes with commas. In combination with -rawfb one might be able to do amusing things (e.g. control non-X devices). To facilitate this, if -rawfb is in effect then the value is stored in X11VNC_RAWFB_STR for the pipe command to use if it wants. Do 'env | grep X11VNC' for more. Built-in pipeinput modes (no external program required): If cmd is "VID" and you are using the -rawfb for a video capture device, then an internal list of keyboard mappings is used to set parameters of the video. The mappings are: "B" and "b" adjust the brightness up and down. "H" and "h" adjust the hue. "C" and "c" adjust the colour. "N" and "n" adjust the contrast. "S" and "s" adjust the size of the capture screen. "I" and "i" cycle through input channels. Up and Down arrows adjust the station (if a tuner) F1, F2, ..., F6 will switch the video capture pixel format to HI240, RGB565, RGB24, RGB32, RGB555, and GREY respectively. See -rawfb video for details. If cmd is "CONSOLE" or "CONSOLEn" where n is a Linux console number, then the linux console keystroke insertion to /dev/ttyN (see -rawfb console) is performed. If cmd begins with "UINPUT" then the Linux uinput module is used to insert both keystroke and mouse events to the Linux console (see -rawfb above). This usually is the /dev/input/uinput device file (you may need to create it with "mknod /dev/input/uinput c 10 223" and insert the module with "modprobe uinput". The UINPUT mode currently only does US keyboards (a scan code option may be added), and not all keysyms are supported. But it is probably more accurate than the "CONSOLE" method. You may want to use the options -cursor none and -nodragging in this mode. Additional tuning options may be supplied via: UINPUT:opt1,opt2,... (a comma separated list). If an option begins with "/" it is taken as the uinput device file. Which uinput is injected can be controlled by an option string made of the characters "K", "M", and "B" (see the -input option), e.g. "KM" allows keystroke and motion but not button clicks. A UINPUT option of the form: accel=f, or accel=fx+fy sets the mouse motion "acceleration". This is used to correct raw mouse relative motion into how much the application cursor moves (x11vnc has no control over, or knowledge of how the windowing application interprets the raw mouse motions). Typically the acceleration for an X display is 2 (see xset "m" option). "f" is a floating point number, e.g. 3.0. Use "fx+fy" if you need to supply different corrections for x and y. Note: the default acceleration is 2.0 since it seems both X and qt-embedded often (but not always) use this value. Even with a correct accel setting the mouse position will get out of sync (probably due to a mouse "threshold" setting where the acceleration doe not apply, set xset(1)). The option reset=N sets the number of ms (default 150) after which the cursor is attempted to be reset (by forcing the mouse to (0, 0) via small increments and then back out to (x, y) in 1 jump), This correction seems to be needed but can cause jerkiness or unexpected behavior with menus, etc. Use reset=0 to disable. If you set the env. var X11VNC_UINPUT_THRESHOLDS then the thresh=n mode will be enabled. It is currently not working well. If |dx| <= thresh and |dy| < thresh no acceleration is applied. Use "thresh=+n" |dx| + |dy| < thresh to be used instead (X11?) Example: -pipeinput UINPUT:accel=4.0 -cursor none If the uinput device has an absolute pointer (as opposed to a normal mouse that is a relative pointer) you can specify the option "abs". Note that a touchpad on a laptop is an absolute device to some degree. This (usually) avoids all the problems with mouse acceleration. If x11vnc has trouble deducing the size of the device, use "abs=WxH". Furthermore, if the device is a touchscreen (assumed to have an absolute pointer) use "touch" or "touch=WxH". For touchscreens, when a mouse button is pressed, a pressure increase is injected, and when the button is released a pressure of zero is injected. If touch has been set, use "touch_always=1" to indicate whenever the mouse moves with no button pressed, a touch event of zero pressure should be sent anyway. Also use "btn_touch=1" to indicate a BTN_TOUCH keystroke press or release should be sent instead of a pressure change. Set "dragskip=n" to skip n dragged mouse touches (with pressure applied) before injecting one. To indicate the pressure that should be sent when there is a button click for a touchscreen device, specify pressure=n, e.g. n=5. The default is n=1. If a touch screen is being used ("touch" above) and it is having its input processed by tslib, you can specify the tslib calibration file via tslib_cal=. For example, tslib_cal=/etc/pointercal. To get accurate or even usable positioning this is required when tslib is in use. The Linux uinput mechanism can be bypassed and one can write input events DIRECTLY to the devices instead. To do this, specify one or more of the following for the input classes: direct_rel= direct_abs= direct_btn= or direct_key=. The file is usually something like /dev/input/event1 but you can specify any device file or pipe. You must specify each one of the above classes even if they correspond to the same device file (rel/abs and btn are often the same.) Look at the file /proc/bus/input/devices to get an idea what is available and the device filenames. Note: The /dev/input/mouse* devices do not seem to work, use the corresponding /dev/input/event* file instead. Any input class not directly specified as above will be handled via the uinput mechanism. To disable creating a uinput device (and thereby discarding unhandled input), specify "nouinput". Examples: -pipeinput UINPUT:direct_abs=/dev/input/event1 this was used on a qtmoko Neo freerunner (armel): -pipeinput UINPUT:touch,tslib_cal=/etc/pointercal, direct_abs=/dev/input/event1,nouinput,dragskip=4 (where the long line has been split into two.) You can set the env. var X11VNC_UINPUT_DEBUG=1 or higher to get debugging output for UINPUT mode. -macnodim For the native MacOSX server, disable dimming. -macnosleep For the native MacOSX server, disable display sleep. -macnosaver For the native MacOSX server, disable screensaver. -macnowait For the native MacOSX server, do not wait for the user to switch back to his display. -macwheel n For the native MacOSX server, set the mouse wheel speed to n (default 5). -macnoswap For the native MacOSX server, do not swap mouse buttons 2 and 3. -macnoresize For the native MacOSX server, do not resize or reset the framebuffer even if it is detected that the screen resolution or depth has changed. -maciconanim n For the native MacOSX server, set n to the number of milliseconds that the window iconify/deiconify animation takes. In -ncache mode this value will be used to skip the animation if possible. (default 400) -macmenu For the native MacOSX server, in -ncache client-side caching mode, try to cache pull down menus (not perfect because they have animated fades, etc.) -macuskbd For the native MacOSX server, use the original keystroke insertion code based on a US keyboard. -macnoopengl For the native MacOSX server, do not use OpenGL for screen capture, but rather use the original, deprecated raw memory access method: addr = CGDisplayBaseAddress(). -macnorawfb For the native MacOSX server, disable the raw memory address screen capture method. MACOSX NOTE: There are some deprecated MacOSX interfaces to inject keyboard and mouse events and the raw memory access method is deprecated as well (however, OpenGL will be preferred if available because it is faster.) One can force not using any deprecated interfaces at compile time by setting -DX11VNC_MACOSX_NO_DEPRECATED=1 in CPPFLAGS. Or to turn them off one by one: -DX11VNC_MACOSX_NO_DEPRECATED_LOCALEVENTS=1, -DX11VNC_MACOSX_NO_DEPRECATED_POSTEVENTS=1 or -DX11VNC_MACOSX_NO_DEPRECATED_FRAMEBUFFER=1 At run time, for testing and workarounds, one can disable them by using: -env X11VNC_MACOSX_NO_DEPRECATED=1 -env X11VNC_MACOSX_NO_DEPRECATED_LOCALEVENTS=1 -env X11VNC_MACOSX_NO_DEPRECATED_POSTEVENTS=1 or -env X11VNC_MACOSX_NO_DEPRECATED_FRAMEBUFFER=1 Note: When doing either of these for the mouse input not everything works currently, e.g. double clicks and wireframing. Also, screen resolution and pixel depth changes will not be automatically detected unless the deprecated framebuffer interfaces are allowed. Conversely, if you are compiling on an older machine that does not have some of the newer interfaces, you may need to specify -DX11VNC_MACOSX_NO_CGEVENTCREATESCROLLWHEELEVENT -DX11VNC_MACOSX_NO_CGEVENTCREATEMOUSEEVENT or -DX11VNC_MACOSX_NO_CGEVENTCREATEKEYBOARDEVENT. Use -DX11VNC_MACOSX_USE_GETMAINDEVICE to regain the very old QuickDraw GetMainDevice() interface (rare...) -gui [gui-opts] Start up a simple tcl/tk gui based on the remote control options -remote/-query described below. Requires the "wish" program to be installed on the machine. "gui-opts" is not required: the default is to start up both the full gui and x11vnc with the gui showing up on the X display in the environment variable DISPLAY. "gui-opts" can be a comma separated list of items. Currently there are these types of items: 1) a gui mode, a 2) gui "simplicity", 3) the X display the gui should display on, 4) a "tray" or "icon" mode, and 5) a gui geometry. 1) The gui mode can be "start", "conn", or "wait" "start" is the default mode above and is not required. "conn" means do not automatically start up x11vnc, but instead just try to connect to an existing x11vnc process. "wait" means just start the gui and nothing else (you will later instruct the gui to start x11vnc or connect to an existing one.) 2) The gui simplicity is off by default (a power-user gui with all options is presented) To start with something less daunting supply the string "simple" ("ez" is an alias for this). Once the gui is started you can toggle between the two with "Misc -> simple_gui". 3) Note the possible confusion regarding the potentially two different X displays: x11vnc polls one, but you may want the gui to appear on another. For example, if you ssh in and x11vnc is not running yet you may want the gui to come back to you via your ssh redirected X display (e.g. localhost:10). If you do not specify a gui X display in "gui-opts" then the DISPLAY environment variable and -display option are tried (in that order). Regarding the x11vnc X display the gui will try to communication with, it first tries -display and then DISPLAY. For example, "x11vnc -display :0 -gui otherhost:0", will remote control an x11vnc polling :0 and display the gui on otherhost:0 The "tray/icon" mode below reverses this preference, preferring to display on the x11vnc display. 4) When "tray" or "icon" is specified, the gui presents itself as a small icon with behavior typical of a "system tray" or "dock applet". The color of the icon indicates status (connected clients) and there is also a balloon status. Clicking on the icon gives a menu from which properties, etc, can be set and the full gui is available under "Advanced". To be fully functional, the gui mode should be "start" (the default). Note that tray or icon mode will imply the -forever x11vnc option (if the x11vnc server is started along with the gui) unless -connect or -connect_or_exit has been specified. So x11vnc (and the tray/icon gui) will wait for more connections after the first client disconnects. If you want only one viewer connection include the -once option. For "icon" the gui just a small standalone window. For "tray" it will attempt to embed itself in the "system tray" if possible. If "=setpass" is appended the n at startup the X11 user will be prompted to set the VNC session password. If = is appended that icon will attempt to embed itself in the window given by hexnumber. Use =noadvanced to disable the full gui. (To supply more than one, use "+" sign). E.g. -gui tray=setpass and -gui icon=0x3600028 Other modes: "full", the default and need not be specified. "-gui none", do not show a gui, useful to override a ~/.x11vncrc setting, etc. 5) When "geom=+X+Y" is specified, that geometry is passed to the gui toplevel. This is the icon in icon/tray mode, or the full gui otherwise. You can also specify width and height, i.e. WxH+X+Y, but it is not recommended. In "tray" mode the geometry is ignored unless the system tray manager does not seem to be running. One could imagine using something like "-gui tray,geom=+4000+4000" with a display manager to keep the gui invisible until someone logs in... More icon tricks, "icon=minimal" gives an icon just with the VNC display number. You can also set the font with "iconfont=...". The following could be useful: "-gui icon=minimal,iconfont=5x8,geom=24x10+0-0" General examples of the -gui option: "x11vnc -gui", "x11vnc -gui ez" "x11vnc -gui localhost:10", "x11vnc -gui conn,host:0", "x11vnc -gui tray,ez" "x11vnc -gui tray=setpass" If you do not intend to start x11vnc from the gui (i.e. just remote control an existing one), then the gui process can run on a different machine from the x11vnc server as long as X permissions, etc. permit communication between the two. FONTS: On some systems the tk fonts can be too small, jagged, or otherwise unreadable. There are 4 env vars you can set to be the tk font you prefer: X11VNC_FONT_BOLD main font for menus and buttons. X11VNC_FONT_FIXED font for fixed width text. X11VNC_FONT_BOLD_SMALL tray icon font. X11VNC_FONT_REG_SMALL tray icon menu font. The last two only apply for the tray icon mode. Here are some examples: -env X11VNC_FONT_BOLD='Helvetica -16 bold' -env X11VNC_FONT_FIXED='Courier -14' -env X11VNC_FONT_REG_SMALL='Helvetica -12' You can put the lines like the above (without the quotes) in your ~/.x11vncrc file to avoid having to specify them on the x11vnc command line. -remote command Remotely control some aspects of an already running x11vnc server. "-R" and "-r" are aliases for "-remote". After the remote control command is sent to the running server the 'x11vnc -remote ...' x11vnc command exits. You can often use the -query command (see below) to see if the x11vnc server processed your -remote command. The default communication channel is that of X properties (specifically X11VNC_REMOTE), and so this command must be run with correct settings for DISPLAY and possibly XAUTHORITY to connect to the X server and set the property. Alternatively, use the -display and -auth options to set them to the correct values. The running server cannot use the -novncconnect option because that disables the communication channel. See below for alternate channels. For example: 'x11vnc -remote stop' (which is the same as 'x11vnc -R stop') will close down the x11vnc server. 'x11vnc -R shared' will enable shared connections, and 'x11vnc -R scale:3/4' will rescale the desktop. To use a different name for the X11 property (e.g. to have separate communication channels for multiple x11vnc's on the same display) set the X11VNC_REMOTE environment variable to the string you want, for example: -env X11VNC_REMOTE=X11VNC_REMOTE_12345 Both sides of the channel must use the same unique name. To run a bunch of commands in a sequence use something like: x11vnc -R 'script:firstcmd;secondcmd;...' Use x11vnc -R script:file=/path/to/file to read commands from a file (can be multi-line and use the comment '#' character in the normal way. The ';' separator must still be used to separate each command.) To not try to contact another x11vnc process and instead just run the command (or query) directly, prefix the command with the string "DIRECT:" The following -remote/-R commands are supported: stop terminate the server, same as "quit" "exit" or "shutdown". ping see if the x11vnc server responds. return is: ans=ping: ping:mystring as above, but use your own unique string. return is: ans=ping:mystring: blacken try to push a black fb update to all clients (due to timings a client could miss it). Same as "zero", also "zero:x1,y1,x2,y2" for a rectangle. refresh send the entire fb to all clients. reset recreate the fb, polling memory, etc. id:windowid set -id window to "windowid". empty or "root" to go back to root window sid:windowid set -sid window to "windowid" id_cmd:cmd cmds: raise, lower, map, unmap, iconify, move:dXdY, resize:dWdH, geom:WxH+X+Y. dX dY, dW, and dH must have a leading "+" or "-" e.g.: move:-30+10 resize:+20+35 also: wm_delete, wm_name:string and icon_name:string. Also id_cmd:win=N:cmd waitmapped wait until subwin is mapped. nowaitmapped do not wait until subwin is mapped. clip:WxH+X+Y set -clip mode to "WxH+X+Y" flashcmap enable -flashcmap mode. noflashcmap disable -flashcmap mode. shiftcmap:n set -shiftcmap to n. notruecolor enable -notruecolor mode. truecolor disable -notruecolor mode. overlay enable -overlay mode (if applicable). nooverlay disable -overlay mode. overlay_cursor in -overlay mode, enable cursor drawing. overlay_nocursor disable cursor drawing. same as nooverlay_cursor. 8to24 enable -8to24 mode (if applicable). no8to24 disable -8to24 mode. 8to24_opts:str set the -8to24 opts to "str". 24to32 enable -24to32 mode (if applicable). no24to32 disable -24to32 mode. visual:vis set -visual to "vis" scale:frac set -scale to "frac" scale_cursor:f set -scale_cursor to "f" viewonly enable -viewonly mode. noviewonly disable -viewonly mode. shared enable -shared mode. noshared disable -shared mode. forever enable -forever mode. noforever disable -forever mode. timeout:n reset -timeout to n, if there are currently no clients, exit unless one connects in the next n secs. tightfilexfer enable filetransfer for NEW clients. notightfilexfer disable filetransfer for NEW clients. ultrafilexfer enable filetransfer for clients. noultrafilexfer disable filetransfer for clients. rfbversion:n.m set -rfbversion for new clients. http enable http client connections. nohttp disable http client connections. deny deny any new connections, same as "lock" nodeny allow new connections, same as "unlock" avahi enable avahi service advertising. noavahi disable avahi service advertising. mdns enable avahi service advertising. nomdns disable avahi service advertising. zeroconf enable avahi service advertising. nozeroconf disable avahi service advertising. connect:host do reverse connection to host, "host" may be a comma separated list of hosts or host:ports. See -connect. Passwords required as with fwd connections. See X11VNC_REVERSE_CONNECTION_NO_AUTH=1 disconnect:host disconnect any clients from "host" same as "close:host". Use host "all" to close all current clients.

Both of these programs are for 'pointer and keyboard' sharing between separate X displays. In general the two displays are usually nearby, e.g. on the same desk, and this allows the user to share a single pointer and keyboard between them. The user moves the mouse to an edge and then the mouse pointer appears to 'jump' to the other display screen. Thus it emulates what a single X server would do for two screens (e.g. :0.0 and :0.1) The illusion of a single Xserver with multiple screens is achieved by forwarding events to the 2nd one via the XTEST extension. What the x11vnc bcx_xattach command does is to perform some pointer movements to try to INDUCE xattach/x2x to 'jump' to the other display. In what follows the 'master' display refers to the one that when it has 'focus' it is basically doing nothing besides watching for the mouse to go over an edge. The 'slave' display refers to the one to which the mouse and keyboard is redirected to once an edge in the master has been crossed. Note that the x11vnc executing the bcx_xattach command MUST be the one connected to the *master* display. Also note that when input is being redirected (via XTEST) from the master display to the slave display, the master display's pointer and keyboard are *grabbed* by xattach/x2x. x11vnc can use this info to verify that the master/slave mode change has taken place correctly. If you specify the "ifneeded" option (see below) and the initial grab state is that of the desired final state, then no pointer movements are injected and "DONE,GRAB_OK" is returned. "str" must contain one of "up", "down", "left", or "right" to indicate the direction of the 'jump'. "str" must also contain one of "master_to_slave" or "slave_to_master" to indicate the type of mode change induced by the jump. Use "M2S" and "S2M" as shorter aliases. "str" may be a "+" separated list of additional tuning options. The "shift=n" option indicates an offset shift position away from (0,0) (default 20). "final=x+y" specifies the final position of the cursor at the end of the normal move sequence; default 30+30. "extra_move=x+y" means to do one more pointer move after "final" to x+y. "dt=n" sets the sleep time in milliseconds between pointer moves (default: 40ms) "retry=n" specifies the maximum number of retries if the grab state change fails. "ifneeded" means to not apply the pointer movements if the initial grab state is that of the desired final state. "nograbcheck" means to not check if the grab state changed as expected and only apply the pointer movements (default is to check the grab states.) If you do not specify "up", etc., to bcx_xattach nothing will be attempted and the command returns the string FAIL,NO_DIRECTION_SPECIFIED. If you do not specify "master_to_slave" or "M2S", etc., to bcx_xattach nothing will be attempted and the command returns the string FAIL,NO_MODE_CHANGE_SPECIFIED. Otherwise, the returned string will contain "DONE". It will be "DONE,GRAB_OK" if the grab state changed as expected (or if "ifneeded" was supplied and the initial grab state was already the desired one.) If the initial grab state was incorrect, but the final grab state was correct then it is "DONE,GRAB_FAIL_INIT". If the initial grab state was correct, but the final grab state was incorrect then it is "DONE,GRAB_FAIL_FINAL". If both are incorrect it will be "DONE,GRAB_FAIL". Under grab failure the string will be followed by ":p1,k1-p2,k2" where p1,k1 indicates the initial pointer and keyboard grab states and p2,k2 the final ones. If GRAB_FAIL or GRAB_FAIL_FINAL occurs, the action will be retried up to 3 times; trying to reset the state and sleeping a bit between each try. Set retry=n to adjust the number of retries, zero to disable retries. Examples: -R bcx_xattach:down+M2S -R bcx_xattach:up+S2M -R bcx_xattach:up+S2M+nograbcheck+dt=30 -R bcx_xattach:down+M2S+extra_move=100+100 or use -Q instead of -R to retrieve the result text. End of the bcx_xattach:str description. The vncconnect(1) command from standard VNC distributions may also be used if string is prefixed with "cmd=" E.g. 'vncconnect cmd=stop'. Under some circumstances xprop(1) can used if it supports -set (see the FAQ). If "-connect /path/to/file" has been supplied to the running x11vnc server then that file can be used as a communication channel (this is the only way to remote control one of many x11vnc's polling the same X display) Simply run: 'x11vnc -connect /path/to/file -remote ...' or you can directly write to the file via something like: "echo cmd=stop > /path/to/file", etc. -query variable Like -remote, except just query the value of "variable". "-Q" is an alias for "-query". Multiple queries can be done by separating variables by commas, e.g. -query var1,var2. The results come back in the form ans=var1:value1,ans=var2:value2,... to the standard output. If a variable is read-only, it comes back with prefix "aro=" instead of "ans=". Some -remote commands are pure actions that do not make sense as variables, e.g. "stop" or "disconnect", in these cases the value returned is "N/A". To direct a query straight to the X11VNC_REMOTE property or connect file use "qry=..." instead of "cmd=..." ans= stop quit exit shutdown ping resend_cutbuffer resend_clipboard resend_primary blacken zero refresh reset close disconnect id_cmd id sid waitmapped nowaitmapped clip flashcmap noflashcmap shiftcmap truecolor notruecolor overlay nooverlay overlay_cursor overlay_yescursor nooverlay_nocursor nooverlay_cursor nooverlay_yescursor overlay_nocursor 8to24 no8to24 8to24_opts 24to32 no24to32 visual scale scale_cursor viewonly noviewonly shared noshared forever noforever once timeout tightfilexfer notightfilexfer ultrafilexfer noultrafilexfer rfbversion deny lock nodeny unlock avahi mdns zeroconf noavahi nomdns nozeroconf connect proxy allowonce allow noipv6 ipv6 noipv4 ipv4 no6 6 localhost nolocalhost listen lookup nolookup accept afteraccept gone shm noshm flipbyteorder noflipbyteorder onetile noonetile solid_color solid nosolid blackout xinerama noxinerama xtrap noxtrap xrandr noxrandr xrandr_mode rotate padgeom quiet q noquiet modtweak nomodtweak xkb noxkb capslock nocapslock skip_lockkeys noskip_lockkeys skip_keycodes sloppy_keys nosloppy_keys skip_dups noskip_dups add_keysyms noadd_keysyms clear_mods noclear_mods clear_keys noclear_keys clear_all clear_locks keystate remap repeat norepeat fb nofb bell nobell sendbell sel nosel primary noprimary setprimary nosetprimary clipboard noclipboard setclipboard nosetclipboard seldir cursorshape nocursorshape cursorpos nocursorpos cursor_drag nocursor_drag cursor show_cursor noshow_cursor nocursor arrow xfixes noxfixes xdamage noxdamage xd_area xd_mem alphacut alphafrac alpharemove noalpharemove alphablend noalphablend xwarppointer xwarp noxwarppointer noxwarp always_inject noalways_inject buttonmap dragging nodragging ncache_cr noncache_cr ncache_no_moveraise noncache_no_moveraise ncache_no_dtchange noncache_no_dtchange ncache_no_rootpixmap noncache_no_rootpixmap ncache_reset_rootpixmap ncrp ncache_keep_anims noncache_keep_anims ncache_old_wm noncache_old_wm ncache_pad ncache noncache ncache_size debug_ncache nodebug_ncache wireframe_mode wireframe wf nowireframe nowf wireframelocal wfl nowireframelocal nowfl wirecopyrect wcr nowirecopyrect nowcr scr_area scr_skip scr_inc scr_keys scr_term scr_keyrepeat scr_parms scrollcopyrect scr noscrollcopyrect noscr fixscreen noxrecord xrecord reset_record pointer_mode pm input_skip allinput noallinput input_eagerly noinput_eagerly input grabkbd nograbkbd grabptr nograbptr grabalways nograbalways grablocal client_input ssltimeout speeds wmdt debug_pointer dp nodebug_pointer nodp debug_keyboard dk nodebug_keyboard nodk keycode keysym ptr fakebuttonevent sleep get_xprop set_xprop wininfo bcx_xattach deferupdate defer setdefer extra_fbur wait_ui wait_bog nowait_bog slow_fb xrefresh wait readtimeout nap nonap sb screen_blank fbpm nofbpm dpms nodpms clientdpms noclientdpms forcedpms noforcedpms noserverdpms serverdpms noultraext ultraext chatwindow nochatwindow chaton chatoff fs gaps grow fuzz snapfb nosnapfb rawfb uinput_accel uinput_thresh uinput_reset uinput_always progressive rfbport http nohttp httpport httpdir enablehttpproxy noenablehttpproxy alwaysshared noalwaysshared nevershared noalwaysshared dontdisconnect nodontdisconnect desktop debug_xevents nodebug_xevents debug_xevents debug_xdamage nodebug_xdamage debug_xdamage debug_wireframe nodebug_wireframe debug_wireframe debug_scroll nodebug_scroll debug_scroll debug_tiles dbt nodebug_tiles nodbt debug_tiles debug_grabs nodebug_grabs debug_sel nodebug_sel dbg nodbg macnosaver macsaver nomacnosaver macnowait macwait nomacnowait macwheel macnoswap macswap nomacnoswap macnoresize macresize nomacnoresize maciconanim macmenu macnomenu nomacmenu macuskbd nomacuskbd noremote aro= noop display vncdisplay icon_mode autoport loop loopbg desktopname guess_desktop guess_dbus http_url auth xauth users rootshift clipshift scale_str scaled_x scaled_y scale_numer scale_denom scale_fac_x scale_fac_y scaling_blend scaling_nomult4 scaling_pad scaling_interpolate inetd privremote unsafe safer nocmds passwdfile unixpw unixpw_nis unixpw_list ssl ssl_pem sslverify stunnel stunnel_pem https httpsredir usepw using_shm logfile o flag rmflag rc norc h help V version lastmod bg sigpipe threads readrate netrate netlatency pipeinput clients client_count pid ext_xtest ext_xtrap ext_xrecord ext_xkb ext_xshm ext_xinerama ext_overlay ext_xfixes ext_xdamage ext_xrandr rootwin num_buttons button_mask mouse_x mouse_y grab_state pointer_pos pointer_x pointer_y pointer_same pointer_root pointer_mask bpp depth indexed_color dpy_x dpy_y wdpy_x wdpy_y off_x off_y cdpy_x cdpy_y coff_x coff_y rfbauth passwd viewpasswd -QD variable Just like -query variable, but returns the default value for that parameter (no running x11vnc server is consulted) -sync By default -remote commands are run asynchronously, that is, the request is posted and the program immediately exits. Use -sync to have the program wait for an acknowledgement from the x11vnc server that command was processed (somehow). On the other hand -query requests are always processed synchronously because they have to wait for the answer. Also note that if both -remote and -query requests are supplied on the command line, the -remote is processed first (synchronously: no need for -sync), and then the -query request is processed in the normal way. This allows for a reliable way to see if the -remote command was processed by querying for any new settings. Note however that there is timeout of a few seconds (see the next paragraph) so if the x11vnc takes longer than that to process the requests the requester will think that a failure has taken place. The default is to wait 3.5 seconds. Or if cmd=stop only 1.0 seconds. If cmd matches 'script:' then it will wait up to 10.0 seconds. Set X11VNC_SYNC_TIMEOUT to the number of seconds you want it to wait. -query_retries str If a query fails to get a response from an x11vnc server, retry up to n times. "str" is specified as n[:t][/match] Optionally the delay between tries may be specified by "t" a floating point time (default 0.5 seconds.) Note: the response is not checked for validity or whether it corresponds to the query sent. The query "ping:mystring" may be used to help uniquely identify the query. Optionally, a matching string after a "/" will be used to check the result text. Up to n retries will take place until the matching string is found in the output text. If the match string is never found the program's exit code is 1; if the match is found it exits with 0. Note that there may be stdout printed for each retry (i.e. multiple lines printed out to stdout.) Example: -query_retries 4:1.5/grab_state -remote_prefix str Enable a remote-control communication channel for connected VNC clients. str is a non-empty string. If a VNC client sends rfbCutText having the prefix "str" then the part after it is processed as though it were sent via 'x11vnc -remote ...'. If it begins with neither 'cmd=' nor 'qry=' then 'qry=' is assumed. Any corresponding output text for that remote control command is sent back to all client as rfbCutText. The returned output is also prefixed with "str". Example: -remote_prefix DO_THIS: Note that enabling -remote_prefix allows the remote VNC viewers to run x11vnc -remote commands. Do not use this option if they are not to be trusted. -noremote Do not process any remote control commands or queries. -yesremote Do process remote control commands or queries. Default: -yesremote A note about security wrt remote control commands. If someone can connect to the X display and change the property X11VNC_REMOTE, then they can remotely control x11vnc. Normally access to the X display is protected. Note that if they can modify X11VNC_REMOTE on the X server, they have enough permissions to also run their own x11vnc and thus have complete control of the desktop. If the "-connect /path/to/file" channel is being used, obviously anyone who can write to /path/to/file can remotely control x11vnc. So be sure to protect the X display and that file's write permissions. See -privremote below. If you are paranoid and do not think -noremote is enough, to disable the X11VNC_REMOTE property channel completely use -novncconnect, or use the -safer option that shuts many things off. -unsafe A few remote commands are disabled by default (currently: id:pick, accept:, gone:, and rawfb:setup:) because they are associated with running external programs. If you specify -unsafe, then these remote-control commands are allowed. Note that you can still specify these parameters on the command line, they just cannot be invoked via remote-control. -safer Equivalent to: -novncconnect -noremote and prohibiting -gui and the -connect file. Shuts off communcation channels. -privremote Perform some sanity checks and disable remote-control commands if it appears that the X DISPLAY and/or connectfile can be accessed by other users. Once remote-control is disabled it cannot be turned back on. -nocmds No external commands (e.g. system(3), popen(3), exec(3)) will be run at all. -allowedcmds list "list" contains a comma separated list of the only external commands that can be run. The full list of associated options is: stunnel, ssl, unixpw, WAIT, zeroconf, id, accept, afteraccept, gone, pipeinput, v4l-info, rawfb-setup, dt, gui, ssh, storepasswd, passwdfile, custom_passwd, findauth, crash. See each option's help to learn the associated external command. Note that the -nocmds option takes precedence and disables all external commands. -deny_all For use with -remote nodeny: start out denying all incoming clients until "-remote nodeny" is used to let them in. ``` These options are passed to LibVNCServer: ``` -rfbport port TCP port for RFB protocol -rfbwait time max time in ms to wait for RFB client -rfbauth passwd-file use authentication on RFB protocol (use 'storepasswd' to create a password file) -rfbversion 3.x Set the version of the RFB we choose to advertise -permitfiletransfer permit file transfer support -passwd plain-password use authentication (use plain-password as password, USE AT YOUR RISK) -deferupdate time time in ms to defer updates (default 40) -deferptrupdate time time in ms to defer pointer updates (default none) -desktop name VNC desktop name (default "LibVNCServer") -alwaysshared always treat new clients as shared -nevershared never treat new clients as shared -dontdisconnect don't disconnect existing clients when a new non-shared connection comes in (refuse new connection instead) -httpdir dir-path enable http server using dir-path home -httpport portnum use portnum for http connection -enablehttpproxy enable http proxy support -progressive height enable progressive updating for slow links -listen ipaddr listen for connections only on network interface with addr ipaddr. '-listen localhost' and hostname work too. libvncserver-tight-extension options: -disablefiletransfer disable file transfer -ftproot string set ftp root ``` Pretty wild huh? Contact me if you have any questions or problems. Personally, I use: ``` x11vnc -rfbauth $HOME/.vnc/passwd -solid ``` x11vnc-0.9.17/doc/SSL-PORTAL.md000066400000000000000000001026341500463450600154700ustar00rootroot00000000000000# Using Apache as an SSL Gateway to multiple x11vnc servers inside a firewall Background: The typical way to allow access to x11vnc (or any other VNC server) running on multiple workstations inside a firewall is via SSH. The user somewhere out on the Internet logs in to the SSH gateway machine and uses port forwarding (e.g. ssh -t -L 5900:myworkstation:5900 user@gateway) to set up the encrypted channel that VNC is then tunneled through. Next he starts up the VNC viewer on the machine where he is sitting directed to the local tunnel port (e.g. localhost:0). The SSH scheme is nice because it is a widely used and well tested login technique for users connecting to machines inside their company or home firewall. For VNC access it is a bit awkward, however, because SSH needs to be installed on the Viewer machine and the user usually has to rig up his own port redirection plumbing (however, see our other tool). Also, some users have restrictive work environments where SSH and similar applications are prohibited (i.e. only outgoing connections to standard WWW ports from a browser are allowed, perhaps mediated by a proxy server). These users have successfully used the method described here for remote access. With the SSL support in x11vnc and the SSL enabled Java VNC viewer applet, a convenient and secure alternative exists that uses the Apache webserver as a gateway. The idea is that the company or home internet connection is already running apache as a web server (either SSL or non-SSL) and we add to it the ability to act as a gateway for SSL VNC connections. The only thing needed on the Viewer side is a Java enabled Web Browser: the user simply enters a URL that starts the entire VNC connection process. No VNC or SSH specific software needs to be installed on the viewer side machine. The stunnel VNC viewer stunnel wrapper script provided (ss_vncviewer) can also take advantage of the method described here with its -proxy option. --- Simpler Solutions: This apache SSL VNC portal solution may be too much for you. It is mainly intended for automatically redirecting to MULTIPLE workstations inside the firewall. If you only have one or two inside machines that you want to access, the method described here is overly complicated! See below for some simpler (and still non-SSH) encrypted setups. Also see the recent (Mar/2010) desktop.cgi x11vnc desktop web login CGI script that achieves much of what the method describes here (especially if its 'port redirection' feature is enabled.) --- There are numerous ways to achieve this with Apache. We present one of the simplest ones here. Important: these sorts of schemes allow incoming connections from anywhere on the Internet to fixed ports on machines inside the firewall. Care must be taken to implement and test thoroughly. If one is paranoid one can (and should) add extra layers of protection. (e.g. extra passwords, packet filtering, SSL certificate verification, etc). Also, it is easy to miss the point that unless precautions are taken to verify SSL Certificates, then the VNC Viewer is vulnerable to man-in-the-middle attacks (but not to the more common passive sniffing attacks). Note that there are hacker tools like dsniff/webmitm and cain that implement SSL Man-In-The-Middle attacks. They rely on the client not bothering to check the cert. --- The Holy Grail: a single https port (443) Before we discuss the self-contained apache examples here, we want to mention that many x11vnc users who read this page and implement the apache SSL VNC portal ask for something that (so far) seems difficult or impossible to do entirely inside apache: * A single port, 443 (the default https:// port), is open to the Internet * It is HTTPS/SSL encrypted * It handles both VNC traffic and Java VNC Applet downloads. * And the server can also serve normal HTTPS webpages, CGI, etc. It is the last item that makes it tricky (otherwise the method described on this page will work). If you are interested in such a solution and are willing to run a separate helper program (connect_switch) look here. Also, see this apache patch. --- Example: The scheme described here sets up apache on the firewall/gateway as a regular Web proxy into the intranet and allows connections to a single fixed port on a limited set of machines. The configuration described in this section does not use the mod_ssl apache module (the optional configuration described in the section "Downloading the Java applet to the browser via HTTPS" does take advantage of mod_ssl) In this example suppose the gateway machine running apache is named "www.gateway.east" (e.g. it may also provide normal web service). We also choose the Internet-facing port for this VNC service to be port 563. One could choose any port, including the default HTTP port 80. Detail: We choose 563 because it is the rarely used SNEWS port that is often allowed by Web proxies for the CONNECT method. The idea is the user may be coming out of another firewall using a proxy (not the one we describe here, that is, the case when two proxies are involved, e.g. one at work and another Apache (described here) at home redirecting into our firewall; the "double proxy" or "double firewall" problem). Using port 563 simplifies things because CONNECT's to it are usually allowed by default. We also assume all of the x11vnc servers on the internal machines are all listening on port 5915 ("-rfbport 5915") instead of the default 5900. This is to limit any unintended proxy redirections to a lesser used port, and also to stay out of the way of normal VNC servers on the same machines. One could obviously implement a scheme that handles different ports, but we just discuss this simple setup here. So we basically assume x11vnc has been started this way on all of the workstations to be granted VNC access: ``` x11vnc -ssl SAVE -http -display :0 -forever -rfbauth ~/.vnc/passwd -rfbport 5915 ``` i.e. we force SSL VNC connections, port 5915, serve the Java VNC viewer applet, and require a VNC password (another option would be -unixpw). The above command could also be run out of inetd(8). It can also be used to autodetect the user's display and Xauthority data. These sections are added to the httpd.conf apache configuration file on www.gateway.east: ``` # In the global section you need to enable these modules. # Note that the ORDER MATTERS! mod_rewrite must be before mod_proxy # (so that we can check the allowed host list via rewrite) # LoadModule rewrite_module modules/mod_rewrite.so LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_connect_module modules/mod_proxy_connect.so LoadModule proxy_ftp_module modules/mod_proxy_ftp.so LoadModule proxy_http_module modules/mod_proxy_http.so LoadModule ssl_module modules/mod_ssl.so # Near the bottom of httpd.conf you put the port 563 virtual host: Listen 563 # Allow proxy CONNECT requests *only* to port 5915. # If the machines use different ports, e.g. 5916 list them here as well: # ProxyRequests On AllowCONNECT 5915 RewriteEngine On # Convenience rules to expand applet parameters.

Note that the listing of allowed internal workstations is done in an external file (/dist/apache/conf/vnc.hosts in the example above), the format is like this: ``` # allowed vnc hosts file: hostname1 15 hostname2 15 ... ``` You list the hostname and the VNC display (always 15 in our example). Only to these hosts will the external VNC viewers be able to connect to (via the HTTP CONNECT method). The above setup requires mod_rewrite and mod_proxy be enabled in the apache web server. In this example they are loaded as modules (and note that mod_rewrite must be listed before mod_proxy); The user at the Java enabled Web browser would simply enter this URL into the browser: http://www.gateway.east:563/vnc/host2 to connect to internal workstation host2, etc. Important: do not put a trailing "/" on the URL, since that will defeat the RewriteRules that look for the hostname at the very end. There will be a number of SSL certificate, etc, dialogs he will have to respond to in addition to any passwords he is required to provide (this depends on how you set up user authentication for x11vnc). If a second Web proxy is involved (i.e. the user's browser is inside another firewall and policy requires using a Web proxy server) then use this URL: http://www.gateway.east:563/vnc/proxy/host2 This will involve downloading a signed java viewer applet jar file that is able to interact with the internal proxy for the VNC connection. See this FAQ for more info on how this works. Note: sometimes with the Proxy case if you see 'Bad Gateway' error you will have to wait 10 or so seconds and then hit reload. This seems to be due to having to wait for a Connection Keepalive to terminate... For completeness, the "trust" cases that skip a VNC certificate dialog (discussed below) would be entered as: ``` http://www.gateway.east:563/vnc/trust/host2 http://www.gateway.east:563/vnc/trust/proxy/host2 ``` You can of course choose shorter or more easy to remember URL formats. Just change the Convenience RewriteRules in httpd.conf. --- Port Variations: Note that you can run this on the default HTTP port 80 instead of port 563. If you do not expect to have a browser connecting from inside a proxying firewall (where sometimes only connections to ports 443 and 563 are allowed) this should be fine. Use "80" instead of "563" in the httpd.conf config file (you may need to merge it with other default port 80 things you have there). Then the URL's will be a bit simpler: ``` http://www.gateway.east/vnc/host2 http://www.gateway.east/vnc/trust/host2 ``` etc. Besides 80 one could use any other random port number (since there are so many port scans on 80, a little obscurity might be useful). One option is to use port "443" (the default https:// port) instead of "563". In this case Apache is not configured for mod_ssl; we just happen to use port "443" in the way any random port would be used. This could be handy if the Viewer side environment is restrictive in that it only allows outgoing connections to ports 80 and 443 (and, say, you didn't want to use port 80, or you wanted to use 80 for something else). Another reason for using 443 would be some web proxy environments only allow the CONNECT method to go to port 443 (and not even the case 563 we use above). --- Details: Let's go through the httpd.conf additions in detail from the top. The LoadModules directives load the necessary apache modules. Note that mod_rewrite must be listed first. If you are compiling from scratch something like this worked for us: ``` ./configure --enable-proxy=shared --enable-proxy-connect=shared --enable-ssl=shared --enable-rewrite=shared --prefix=/dist/apache ``` Then the VirtualHost *:563 virtual host section starts. The "ProxyRequests On" and "AllowCONNECT 5915" enable the web server to forward proxy requests to port 5915 (and only this port) INSIDE the firewall. Think about the implications of this thoroughly and test it carefully. The RewriteRule's are for convenience only so that the URL entered into the Web browser does not need the various extra parameters, e.g.: ``` http://www.gateway.east:563/vnc/host2/index.vnc?CONNECT=host2+5915&PORT=563,blah,blah... ``` (or otherwise make direct edits to index.vnc to set these parameters). The forceProxy=yes parameter is passed to the applet to force the use of a outgoing proxy socket connection. Use it only if the Web browser is inside a separate Web proxying environment (i.e. large corporation) The rewrites with parameter urlPrefix are described under Tricks for Better Response. The "trust" ones (also described under Tricks) with trustAllVncCerts tell the Java VNC applet to skip a dialog asking about the VNC Certificate. They are a bit faster and more reliable than the original method. In the best situation they lead to being logged in 20 seconds or less (without them the time to login can be much longer since a number of connections must timeout). All of the x11vnc Java Viewer applet parameters are described in the file classes/ssl/README The external file /dist/apache/conf/vnc.hosts containing the allowed VNC server hostnames is read in. Its 2nd column contains the VNC display of the host (always 15 in our example; if you make it vary you will need to adjust some lines in the httpd.conf accordingly, e.g. AllowCONNECT). This list is used to constrain both the Jar file download URL and the proxy CONNECT the VNC viewer makes to only the intended VNC servers. Limiting the proxy CONNECT is done with the two sets of RewriteCond conditions. Limiting the Jar file download URL is done in the remaining 4 RewriteRule's. Note that these index.vnc and VncViewer.jar downloads to the browser are not encrypted via SSL, and so in principle could be tampered with by a really bad guy. The subsequent VNC connection, however, is encrypted through a single SSL connection (it makes a CONNECT straight to x11vnc). See below for how to have these initial downloads encrypted as well (if the apache web server has SSL/mod_ssl, i.e. https, enabled and configured). Unfortunately the Java VNC viewer applet currently is not able to save its own list of Certificates (e.g. the user says trust this VNC certificate 'always'). This is because an applet it cannot open local files, etc. Sadly, the applet cannot even remember certificates in the same browser session because it is completely reinitialized for each connection (see below). --- Too Much? If these apache rules are a little too much for you, there is a little bit simpler scheme where you have to list each of the individual machines in the httpd.conf and ssl.conf files. It may be a little more typing to maintain, but perhaps being more straight forward (less RewriteRule's) is desirable. --- Problems? To see example x11vnc output for a successful https://host:5900/ connection with the Java Applet see This Page. --- Some Ideas for adding extra authentication, etc. for the paranoid: * VNC passwords: -rfbauth, -passwdfile, or -usepw. Even adding a simple company-wide VNC password helps block unwanted access. * Unix passwords: -unixpw * SSL Client certificates: -sslverify * Apache AuthUserFile directive: .htaccess, etc. * Filter connections based on IP address or hostname. * Use Port-knocking on your firewall as described in: Enhanced TightVNC Viewer (ssvnc). * Add proxy password authentication (requires Viewer changes?) * Run a separate instance of Apache that provides this VNC service so it can be brought up and down independently of the normal web server. * How secure is the Client side? Public machines in internet cafes, etc, are often hacked, with backdoors and VNC servers of their own. Prefer using your own firewalled laptop to a public machine. --- Using non-Java viewers with this scheme: The ss_vncviewer stunnel wrapper script for VNC viewers has the -proxy option that can take advantage of this method. ``` ss_vncviewer -proxy www.gateway.east:563 host1:15 ``` For the case of the "double proxy" situation (see below) supply both separated by a comma. ``` ss_vncviewer -proxy proxy1.foobar.com:8080,www.gateway.east:563 host1:15 ``` For the Enhanced TightVNC Viewer (ssvnc) GUI (it uses ss_vncviewer on Unix) put 'host1:15' into the 'VNC Server' entry box, and here are possible Proxy/Gateway entries ``` Proxy/Gateway: www.gateway.east:563 Proxy/Gateway: proxy1.foobar.com:8080,www.gateway.east:563 ``` then click on the 'Connect' button. --- Downloading the Java applet to the browser via HTTPS: To have the Java applet downloaded to the user's Web Browser via an encrypted (and evidently safer) SSL connection the Apache webserver should be configured for SSL via mod_ssl. It is actually possible to use the x11vnc Key Management utility "-sslGenCert" to generate your Apache/SSL .crt and .key files. (In brief, run something like "x11vnc -sslGenCert server self:apache" then copy the resulting self:apache.crt file to conf/ssl.crt/server.crt and extract the private key part from self:apache.pem and paste it into conf/ssl.key/server.key). Setting the env var REQ_ARGS='-days 1095' before running x11vnc will bump up the expiration date (3 years in this case). Or you can use the standard methods described in the Apache mod_ssl documentation to create your keys. Then restart Apache, usually something like "apachectl stop" followed by "apachectl startssl" In addition to the above sections in httpd.conf one should add the following to ssl.conf: ``` SSLProxyEngine On RewriteEngine On # Convenience rules to expand applet parameters. These do not have a traili ng "/" # # /vnc http jar file downloading: # RewriteRule /vnc/([^/]+)$ /vnc/$1/index.vnc?CONNECT=$1+5915&PORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vnc_2F_$1 [R,NE,L] RewriteRule /vnc/proxy/([^/]+)$ /vnc/$1/proxy.vnc?CONNECT=$1+5915&PORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vnc_2F_$1&forceProxy=yes [R,N E,L] # # (we skipped the "trust" ones above, put them in if you like) # # /vncs https jar file downloading: # RewriteRule /vncs/([^/]+)$ /vncs/$1/index.vnc?CONNECT=$1+5915&PORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1 [R,NE,L] RewriteRule /vncs/proxy/([^/]+)$ /vncs/$1/proxy.vnc?CONNECT=$1+5915&PORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1&forceProxy=yes [R,NE,l] RewriteRule /vncs/trust/([^/]+)$ /vncs/$1/index.vnc?CONNECT=$1+5915&PORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1&trustAllVncCerts=yes [R,NE,L] RewriteRule /vncs/trust/proxy/([^/]+)$ /vncs/$1/proxy.vnc?CONNECT=$1+5915&PORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1&forceProxy=yes&trustAllVncCerts=yes [R,NE,L] # Convenience rules used for the connect_switch helper (requires Listen 127.0.0.1:443 above): # RewriteRule /vnc443/([^/]+)$ /vncs/$1/index.vnc?CONNECT=$1+5915&PORT=443&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1 [R,NE,L] RewriteRule /vnc443/proxy/([^/]+)$ /vncs/$1/proxy.vnc?CONNECT=$1+5915&PORT=443&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1&forceProxy=yes [R,NE,L] RewriteRule /vnc443/trust/([^/]+)$ /vncs/$1/index.vnc?CONNECT=$1+5915&PORT=443&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1&trustAllVncCerts=yes [R,NE,L] RewriteRule /vnc443/trust/proxy/([^/]+)$ /vncs/$1/proxy.vnc?CONNECT=$1+5915&PORT=443&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1&forceProxy=yes&trustAllVncCerts=yes [R,NE,L] # Read in the allowed host to vnc display mapping file.

The user could then point the Web Browser to: ``` https://www.gateway.east/vnc/host2 ``` or ``` https://www.gateway.east/vnc/proxy/host2 ``` for the "double proxy" case. (Important: do not put a trailing "/" on the URL, since that will defeat the RewriteRules.) As with the httpd.conf case, the external file (/dist/apache/conf/vnc.hosts in the above example) contains the hostnames of the allowed VNC servers. Note that inside the firewall the Java applet download traffic is not encrypted (only over the Internet is SSL used) for these cases: ``` https://www.gateway.east/vnc/host2 https://www.gateway.east/vnc/proxy/host2 ``` However for the special "vncs" rules above: ``` https://www.gateway.east/vncs/host2 ``` the Java applet download is encrypted via SSL for both legs. Note that the two legs are two separate SSL sessions. So the data is decrypted inside an apache process and reencrypted by the apache process for the 2nd SSL session inside the same apache process (a very small gap one might overlook). The "vncs/trust" ones are like the "trust" ones described earlier ``` https://www.gateway.east/vncs/trust/mach2 ``` and similarly for the httpsPort ones. See Tricks for Better Response. In all of the above cases the VNC traffic from Viewer to x11vnc is encrypted end-to-end in a single SSL session, even for the "double proxy" case because the CONNECT method is used (there are actually two CONNECT's for the "double proxy" case). This part (the VNC traffic) is the most important part to have encrypted. Note that the Certificate dialogs the user has in his web browser will be for the Apache Certificate, while for the Java applet it will be the x11vnc certificate. Note also that you can have Apache serve up the Jar file VncViewer.jar and/or index.vnc/proxy.vnc instead of each x11vnc if you want to. The rules in ssl.conf are similar to the ones in httpd.conf and so are not discussed in detail. The only really new thing is the /vncs handling to download the applet jar via HTTPS on port 5915. The special entries "/vnc443" are only used for the special helper program (connect_switch) for the https port 443 only mode discussed here. --- INETD automation: The "single-port" (i.e. 5915) HTTPS applet download and VNC connection aspect shown here is convenient and also enables having x11vnc run out of inetd. That way x11vnc is run on demand instead of being run all the time (the user does not have to remember to start it). The first connections to inetd download index.vnc and the Jar file (via https) and the the last connection to inetd establishes the SSL VNC connection. Since x11vnc is restarted for each connection, this will be a bit slower than the normal process. For example, the /etc/inetd.conf line could be: ``` 5915 stream tcp nowait root /usr/sbin/tcpd /usr/local/bin/x11vnc_ssl.sh ``` where the script x11vnc_ssl.sh looks something like this: ``` #!/bin/sh /usr/local/bin/x11vnc -inetd -oa /var/log/x11vnc-15.log \ -ssl SAVE -http -unixpw -localhost \ -display :0 -auth /home/THE_USER/.Xauthority ``` where, as usual, the inetd launching needs to know which user is typically using the display on that machine. One could imagine giving different users different ports, 5915, 5916, etc. to distinguish (then the script would need to be passed the username). mod_rewrite could be used to automatically map username in the URL to his port number. A better way is to use the "-display WAIT:cmd=FINDDISPLAY" feature to autodetect the user and Xauthority data: ``` #!/bin/sh /usr/local/bin/x11vnc -inetd -oa /var/log/x11vnc-15.log \ -ssl SAVE -http -unixpw -localhost -users unixpw= \ -find ``` (we have used the alias -find for "-display WAIT:cmd=FINDDISPLAY".) This way the user must supply his Unix username and password and then his display and Xauthority data on that machine will be located and returned to x11vnc to allow it to attach. If he doesn't have a display running on that machine or he fails to log in correctly, the connection will be dropped. The variant "-display WAIT:cmd=FINDCREATEDISPLAY" (aliased by "-create") will actually create a (virtual or real) X server session for the user if one doesn't already exist. See here for details. To enable inetd operation for the non-HTTPS Java viewer download (port 5815 in the above httpd.conf example) you will need to run x11vnc in HTTPONCE mode on port 5815: For example, the /etc/inetd.conf line could be: ``` 5815 stream tcp nowait root /usr/sbin/tcpd /usr/local/bin/x11vnc \ -inetd -prog /usr/local/bin/x11vnc -oa /var/log/x11vnc-15.log \ -http_ssl -display WAIT:cmd=HTTPONCE ``` where the long inetd.conf line has been split. Note how the -http_ssl tries to automatically find the .../classes/ssl subdirectory. This requires the -prog option available in x11vnc 0.8.4 (a shell script wrapper, e.g. /usr/local/bin/x11vnc_http.sh can be used to work around this). Also note the use of "-ssl SAVE" above. This way a saved server.pem is used for each inetd invocation (rather generating a new one each time as happens for "-ssl TMP"). Note that it cannot have a protecting passphrase because inetd will not be able to supply it. Another option is: ``` 5815 stream tcp nowait root /usr/sbin/tcpd /usr/local/bin/x11vnc \ -inetd -httpdir /usr/local/share/x11vnc/classes/ssl \ -oa /var/log/x11vnc-15.log -display WAIT:cmd=HTTPONCE ``` (this also requires a feature found in x11vnc 0.8.4). --- Other Ideas: - The above schemes work, but they are a bit complicated with all of the rigging. There should be more elegant ways to configure Apache to do these, but we have not found them (please let us know if you discover something nice). However, once this scheme has been set up and is working it is easy to maintain and add/delete workstations, etc. - In general Apache is not required, but it makes things convenient. The firewall itself could do the port redirection via its firewall rules. Evidently different Internet-facing ports would be required for each workstation. This could be set up using iptables rules for example. If there were just one or two machines this would be the easiest method. For example: ``` iptables -t nat -A PREROUTING -p tcp -d 24.35.46.57 --dport 5901 -j DNAT --to-destination 192.168.1.2:5915 iptables -t nat -A PREROUTING -p tcp -d 24.35.46.57 --dport 5902 -j DNAT --to-destination 192.168.1.3:5915 ``` Where 24.35.46.57 is the internet IP address of the gateway. In this example 24.35.46.57:5901 is redirected to the internal machine 192.168.1.2:5915 and 24.35.46.57:5902 is redirected to another internal machine 192.168.1.3:5915, both running x11vnc -ssl ... in SSL mode. For this example, the user would point the web browser to, e.g.: ``` https://24.35.46.57:5901/?PORT=5901 ``` or using the stunnel wrapper script: ``` ss_vncviewer 24.35.46.57:1 ``` One can achieve similar things with dedicated firewall/routers (e.g. Linksys) using the device's web or other interface to configure the firewall. If the user may be coming out of a firewall using a proxy it may be better to redirect ports 443 and 563 (instead of 5901 and 5902) to the internal machines so that the user's proxy will allow CONNECTing to them. - The redirection could also be done at the application level using a TCP redirect program (e.g. ip_relay or fancier ones). Evidently more careful internal hostname checking, etc., could be performed by the special purpose application to add security. See connect_switch which is somewhat related. - One might imagine the ProxyPass could be done for the VNC traffic as well (for the ssl.conf case) to avoid the CONNECT proxying completely (which would be nice to avoid). Unfortunately we were not able to get this to work. Since HTTP is a request-response protocol (as opposed to a full bidirectional link required by VNC that CONNECT provides) this makes it difficult to do. It may be possible, but we haven't found out how yet. All of the x11vnc Java Viewer applet parameters are described in the file classes/ssl/README --- Tricks for Better Response and reliability: The "original scheme" using httpd.conf and ssl.conf rewrites without urlPrefix and trustAllVncCerts above should work OK, but may lead to slow and/or unreliable loading of the applet and final connection to x11vnc. The following are what I do now to get better response and reliability. YMMV. The problem with the "original scheme" is that there is a point where the VNC Viewer applet can try up to 3 times to retrieve the x11vnc certificate, since it needs to get it to show it to you and ask you if you accept it. This can add about 45 seconds to the whole process (which takes 1 to 1.5 minutes with all the dialogs) since a couple of those connections must time out. The "trust" items in the config add a parameter trustAllVncCerts=yes similar to the forceProxy=yes parameter. This can cut the total time to the VNC password prompt down to 15 seconds which is pretty good. (Note by ignoring the certificate this does not protect against man-in-the-middle attacks which are rare, but maybe the won't be so rare in the future... see dsniff/webmitm and cain) First make sure the x11vnc SSL certificate+key is the same as Apache's. (otherwise you may get one extra dialog and/or one extra connection that has to time out). The following RewriteRule's are the same now advocated in the instructions above. The httpsPort and urlPrefix= parameters give hints to the applet to improve connecting: This is what goes in httpd.conf: ``` RewriteEngine On RewriteRule /vnc/([^/]+)$ /vnc/$1/index.vnc?CONNECT=$1+5915&PORT=563&urlPrefix=_2F_vnc_2F_$1 [R,NE] RewriteRule /vnc/trust/([^/]+)$ /vnc/$1/index.vnc?CONNECT=$1+5915&PORT=563&urlPrefix=_2F_vnc_2F_$1&trustAllVncCerts=yes [R,NE] RewriteRule /vnc/proxy/([^/]+)$ /vnc/$1/proxy.vnc?CONNECT=$1+5915&PORT=563&urlPrefix=_2F_vnc_2F_$1&forceProxy=yes [R,NE] RewriteRule /vnc/trust/proxy/([^/]+)$ /vnc/$1/proxy.vnc?CONNECT=$1+5915&PORT=563&urlPrefix=_2F_vnc_2F_$1&forceProxy=yes&trustAllVncCerts=yes [R,NE] ``` The httpsPort and urlPrefix provide useful hints to the VNC Viewer applet when it connects to x11vnc to glean information about Proxies, certificates, etc. This is what goes into ssl.conf: ``` RewriteEngine On RewriteRule /vnc/([^/]+)$ /vnc/$1/index.vnc?CONNECT=$1+5915&PORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vnc_2F_$1 [R,NE] RewriteRule /vnc/proxy/([^/]+)$ /vnc/$1/proxy.vnc?CONNECT=$1+5915&PORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vnc_2F_$1&forceProxy=yes [R,NE] RewriteRule /vncs/([^/]+)$ /vncs/$1/index.vnc?CONNECT=$1+5915&PORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1 [R,NE] RewriteRule /vncs/proxy/([^/]+)$ /vncs/$1/proxy.vnc?CONNECT=$1+5915&PORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1&forceProxy=yes [R,NE] RewriteRule /vncs/trust/([^/]+)$ /vncs/$1/index.vnc?CONNECT=$1+5915&PORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1&trustAllVncCerts=yes [R,NE] RewriteRule /vncs/trust/proxy/([^/]+)$ /vncs/$1/proxy.vnc?CONNECT=$1+5915&PORT=563&httpsPort=443&GET=1&urlPrefix=_2F_vncs_2F_$1&forceProxy=yes&trustAllVncCerts=yes [R,NE] ``` The rest is the same. The httpsPort and urlPrefix and GET provide useful hints to the VNC Viewer applet when it connects to x11vnc to glean information about Proxies, certificates, etc, and also for the ultimate VNC connection (GET speeds this up by sending a special HTTP GET to cause x11vnc to immediately switch to the VNC protocol). To turn these into URLs, as was done above, take the string in the RewriteRule, e.g. /vncs and turn it into https://gateway/vncs/machinename Similarly for non-https: http://gateway:563/vnc/machinename If you use the 'trust' ones, you are performing NO checks, visual or otherwise, on the VNC SSL certificate. It is trusted without question. This speeds things up because it avoids a dialog about certificates, but of course has some risk WRT Man in the Middle attacks. I don't recommend them. It is better to use /vnc or /vncs and the first time you connect carefully check the Certificate and then tell your Browser and Java Virtual Machine to trust the certificate 'Always'. Then if you later get an unexpected dialog, you know something is wrong. Nearly always it is just a changed or expired certificate, but better safe than sorry... x11vnc-0.9.17/doc/SSL.md000066400000000000000000000734021500463450600144710ustar00rootroot00000000000000# Notes on x11vnc SSL Certificates and Key Management The simplest scheme ("x11vnc -ssl TMP") is where x11vnc generates a temporary, self-signed certificate each time (automatically using openssl(1)) and the VNC viewer client accepts the certificate without question (e.g. user clicks "Yes" in a dialog box. Perhaps the dialog allows them to view the certificate too). Also note stunnel's default is to quietly accept all certificates. The encryption this provides protects against all passive sniffing of the VNC traffic and passwords on the network and so it is quite good, but it does not prevent a Man-In-The-Middle active attack: e.g. an attacker intercepts the VNC client stream and sends it his own Public key for SSL negotiation (pretending to be the server). Then it makes a connection to SSL x11vnc itself and forwards the data back and forth. He can see all the traffic and modify it as well. Most people don't seem to worry about Man-In-The-Middle attacks these days; they are more concerned about passive sniffing of passwords, etc. Perhaps someday that will change if attack tools are used more widely to perform the attack. NOTE: There are hacker tools like dsniff/webmitm and cain that implement SSL Man-In-The-Middle attacks. They all rely on the client not bothering to check that the cert is valid. If you are not worried about Man-In-The-Middle attacks you do not have to read the techniques described in the rest of this document. To prevent Man-In-The-Middle attacks, certificates must somehow be verified. This requires the VNC client side have some piece of information that can be used to verify the SSL x11vnc server. Alternatively, although rarely done, x11vnc can verify VNC Clients' certificates, see the -sslverify option that is discussed below. There are a number of ways to have the client authenticate the SSL x11vnc server. The quickest way perhaps would be to copy (safely) the certificate x11vnc prints out: ``` 26/03/2006 21:12:00 Creating a temporary, self-signed PEM certificate... ... -----BEGIN CERTIFICATE----- MIIC4TCCAkqgAwIBAgIJAMnwCaOjvEKaMA0GCSqGSIb3DQEBBAUAMIGmMQswCQYD VQQGEwJBVTEOMAwGA1UEBxMFTGludXgxITAfBgNVBAsTGGFuZ2VsYS0xMTQzNDI1 NTIwLjQxMTE2OTEPMA0GA1UEChMGeDExdm5jMS4wLAYDVQQDEyV4MTF2bmMtU0VM (more lines) ... -----END CERTIFICATE----- ``` to the client machine(s) and have the client's SSL machinery (e.g. stunnel, Web Browser, or Java plugin) import the certificate. That way when the connection to x11vnc is made the client can verify that is it the desired server on the other side of the SSL connection. So, for example suppose the user is using the SSL enabled Java VNC Viewer and has incorporated the x11vnc certificate into his Web browser on the viewing side. If he gets a dialog that the certificate is not verified he knows something is wrong. It may be a Man-In-The-Middle attack, but more likely x11vnc certificate has changed or expired or his browser was reinstalled and/or lost the certificate, etc, etc. As another example, if the user was using stunnel with his VNC viewer (this is mentioned in this FAQ), e.g. STUNNEL.EXE on Windows, then he would have to set the "CAfile = path-to-the-cert" and "verify = 2" options in the stunnel.conf file before starting up the tunnel. If a x11vnc certificate cannot be verified, stunnel will drop the connection (and print a failure message in its log file). A third example, using the VNC viewer on Unix with stunnel the wrapper script can be used this way: "ss_vncviewer -verify ./x11vnc.crt far-away.east:0" where ./x11vnc.crt is the copied certificate x11vnc printed out. As fourth example, our SSVNC enhanced tightvnc viewer can also use these certificate files for server authentication. You can load them via the SSVNC 'Certs...' dialog and set 'ServerCert' to the certificate file you safely copied there. Note that in principle the copying of the certificate to the client machine(s) itself could be altered by a Man-In-The-Middle attack! You can't win; it is very difficult to be completely secure. It is unlikely the attacker could predict how you were going to send it unless you had, say, done it many times before the same way. SSH is a very good way to send it (but of course it too depends on public keys being sent unaltered between the two machines!). If you are really paranoid, I'm sure you'll figure out a really good way to transport the certificates. See the Certificate Authority scheme below for a way to make this easier (you just have to do it once). --- ## Saving SSL certificates and keys Now, it would be very inconvenient to copy the new temporary certificate every time x11vnc is run in SSL mode. So for convenience there is the "SAVE" keyword to instruct x11vnc to save the certificate it creates: ``` x11vnc -ssl SAVE -display :0 ... ``` This behavior is now the default, you must use "TMP" for a temporary one. It will save the certificate and private key in these files: ``` ~/.vnc/certs/server.crt ~/.vnc/certs/server.pem ``` The ".crt" file contains only the certificate and should be safely copied to the VNC Viewer machine(s) that will be authenticating the x11vnc server. The ".pem" file contains both the certificate and the private key and should be kept secret. (If you don't like the default location ~/.vnc/certs, e.g. it is on an NFS share and you are worried about local network sniffing, use the -ssldir dir option to point to a different directory.) So the next time you run "x11vnc -ssl SAVE ..." it will read the server.pem file directly instead of creating a new one. You can manage multiple SSL x11vnc server keys in this simple way by using: ``` x11vnc -ssl SAVE-key2 -display :0 ... ``` etc, where you put whatever name you choose for the key after "SAVE-". E.g. "-ssl SAVE-fred". Also, if you want to be prompted to possibly change the made up names, etc. that x11vnc creates (e.g. "x11vnc-SELF-SIGNED-CERT-7762" for the CommonName) for the certificates distinguished name (DN), then use "x11vnc -ssl SAVE_PROMPT ...", "x11vnc -ssl SAVE_PROMPT-fred ..." etc. when you create the key the first time. Tip: when prompting, if you choose the CommonName entry to be the full internet hostname of the machine the clients will be connecting to then that will avoid an annoying dialog box in their Web browsers that warn that the CommonName doesn't match the hostname. --- ## Passphrases for server keys Well, since now with the "SAVE" keyword the certificate and key will be longer lived, one can next worry about somebody stealing the private key and pretending to be the x11vnc server! How to guard against this? The first is that the file is created with perms 600 (i.e. -rw-------) to make it harder for an untrusted user to copy the file. A better way is to also encrypt the private key with a passphrase. You are prompted whether you want to do this or not when the key is first created under "-ssl SAVE" mode ("Protect key with a passphrase? y/n"). It is suggested that you use a passphrase. The inconvenience is every time you run "x11vnc -ssl SAVE ..." you will need to supply the passphrase to access the private key: ``` 06/04/2006 11:39:11 using PEM /home/runge/.vnc/certs/server.pem 0.000s ``` A passphrase is needed to unlock an OpenSSL private key (PEM file). ``` Enter passphrase> ``` before x11vnc can continue. --- ## Being your own Certificate Authority A very sophisticated way that scales well if the number of users is large is to use a Certificate Authority (CA) whose public certificate is available to all of the VNC clients and whose private key has been used to digitally sign the x11vnc server certificate(s). The idea is as follows: * A special CA cert and key is generated. * Its private key is always protected by a good passphrase since it is only used for signing. * The CA cert is (safely) distributed to all machines where VNC clients will run. * One or more x11vnc server certs and keys are generated. * The x11vnc server cert is signed with the CA private key. * x11vnc is run using the server key. (e.g. "-ssl SAVE") * VNC clients (viewers) can now authenticate the x11vnc server because they have the CA certificate. The advantage is the CA cert only needs to be distributed once to the various machines, that can be done even before x11vnc server certs are generated. As above, it is important the CA private key and the x11vnc server key are kept secret, otherwise someone could steal them and pretend to be the CA or the x11vnc server if they copied the key. It is recommended that the x11vnc server keys are also protected via a passphrase (see the previous section). Optionally, VNC viewer certs and keys could also be generated to enable the x11vnc server to authenticate each client. This is not normally done (usually a simple viewer password scheme is used), but this can be useful in some situations. These optional steps go like this: * One or more VNC client certs and keys are generated. * These VNC client certs are signed with the CA private key. * The VNC client certs+keys are safely distributed to the corresponding client machines. * x11vnc is told to verify clients by using the CA cert. (e.g. "-sslverify CA") * When VNC clients (viewers) connect, they must authenticate themselves to x11vnc by using their client key. Again, it is a good idea if the client private keys are protected with a passphrase, otherwise if stolen they could be used to gain access to the x11vnc server. Once distributed to the client machines, there is no need to keep the client key on the CA machine that generated and signed it. You can keep the client certs if you like because they are public. --- ## How to do the above CA steps with x11vnc Some utility commands are provided to ease the cert+key creation, signing, and management: -sslGenCA, -sslGenCert, -sslDelCert, -sslEncKey, -sslCertInfo. They basically run the openssl(1) command for you to manage the certs/keys. It is required that openssl(1) is installed on the machine and available in PATH. All commands can be pointed to an alternate toplevel certificate directory via the -ssldir option if you don't want to use the default ~/.vnc/certs. 1. To generate your Certificate Authority (CA) cert and key run this: ``` x11vnc -sslGenCA ``` Follow the prompts, you can modify any informational strings you care to. You will also be required to encrypt the CA private key with a passphrase. This generates these files: ``` ~/.vnc/certs/CA/cacert.pem (the CA public certificate) ~/.vnc/certs/CA/private/cakey.pem (the encrypted CA private key) ``` If you want to use a different directory use -ssldir It must supplied with all subsequent SSL utility options to point them to the correct directory. 2. To generate a signed x11vnc server cert and key run this: ``` x11vnc -sslGenCert server ``` As with the CA generation, follow the prompts and you can modify any informational strings that you care to. This will create the files: ``` ~/.vnc/certs/server.crt (the server public certificate) ~/.vnc/certs/server.pem (the server private key + public cert) ``` It is recommended to protect the server private key with a passphrase (you will be prompted whether you want to). You will need to provide it whenever you start x11vnc using this key. 3. Start up x11vnc using this server key: ``` x11vnc -ssl SAVE -display :0 ... ``` (SAVE corresponds to server.pem, see -sslGenCert server somename info on creating additional server keys, server-somename.crt ...) 4. Next, safely copy the CA certificate to the VNC viewer (client) machine(s). Perhaps: ``` scp ~/.vnc/CA/cacert.pem clientmachine:. ``` 5. Then the tricky part, make it so the SSL VNC Viewer uses this certificate! There are a number of ways this might be done, it depends on what your client and/or SSL tunnel is. Some examples: For the SSL Java VNC viewer supplied with x11vnc in classes/ssl/VncViewer.jar or classes/ssl/SignedVncViewer.jar: * Import the cacert.pem cert into your Web Browser (e.g. Edit -> Preferences -> Privacy & Security -> Manage Certificates -> WebSites -> Import) * Or Import the cacert.pem cert into your Java Plugin (e.g. run ControlPanel, then Security -> Certificates -> Secure Site -> Import) When importing, one would give the browser/java-plugin the path to the copied cacert.pem file in some dialog. Note that the Web browser or Java plugin is used for the server authentication. If the user gets a "Site not verified" message while connecting he should investigate further. For the use of stunnel (e.g. on Windows) one would add this to the stunnel.conf: ``` # stunnel.conf: client = yes options = ALL CAfile = /path/to/cacert.pem # or maybe C:\path\to\cacert.pem [myvncssl] accept = 5901 connect = far-away.east:5900 ``` (then point the VNC viewer to localhost:1). Here is an example for the Unix stunnel wrapper script ss_vncviewer in our SSVNC package: ``` ss_vncviewer -verify ./cacert.pem far-away.east:0 ``` Our SSVNC enhanced tightvnc viewer GUI can also use the certificate file for server authentication. You can load it via the SSVNC 'Certs...' dialog and set 'ServerCert' to the cacert.pem file you safely copied there. --- ## Tricks for server keys To create additional x11vnc server keys do something like this: ``` x11vnc -sslGenCert server myotherkey ``` and use it this way: ``` x11vnc -ssl SAVE-myotherkey ... ``` The files will be ~/.vnc/certs/server-myotherkey.{crt,pem} You can also create a self-signed server key: ``` x11vnc -sslGenCert server self:third_key ``` and use it this way: ``` x11vnc -ssl SAVE-self:third_key ... ``` This key is not signed by your CA. This can be handy to have a key set separate from your CA when you do not want to create a 2nd CA cert+key. --- ## Using external CA's You don't have to use your own CA cert+key, you can use a third party's instead. Perhaps you have a company-wide CA or you can even have your x11vnc certificate signed by a professional CA (e.g. www.thawte.com or www.verisign.com or perhaps the free certificate service www.startcom.org or www.cacert.org). The advantage to doing this is that the VNC client machines will already have the CA certificates installed and you don't have to install it on each machine. To generate an x11vnc server cert+key this way you should generate a "request" for a certicate signing something like this (we use the name "external" in this example, it could be anything you want): ``` x11vnc -sslGenCert server req:external ``` This will create the request file: ``` ~/.vnc/certs/server-req:external.req ``` Which you should send to the external CA. When you get the signed certificate back from them, save it in the file: ``` ~/.vnc/certs/server-req:external.crt ``` and create the .pem this way: ``` mv ~/.vnc/certs/server-req:external.key ~/.vnc/certs/server-req:external.pem chmod 600 ~/.vnc/certs/server-req:external.pem cat ~/.vnc/certs/server-req:external.crt >> ~/.vnc/certs/server-req:external.pem ``` You also rename the two files (.crt and .pem) to have a shorter basename if you like. E.g.: ``` mv ~/.vnc/certs/server-req:external.pem ~/.vnc/certs/server-ext.pem mv ~/.vnc/certs/server-req:external.crt ~/.vnc/certs/server-ext.crt ``` and the use via "x11vnc -ssl SAVE-ext ...", etc. On the viewer side make sure the external CA's certificate is installed an available for the VNC viewer software you plan to use. --- ## Using Client Keys for Authentication You can optionally create certs+keys for your VNC client machines as well. After distributing them to the client machines you can have x11vnc verify the clients using SSL. Here is how to do this: ``` x11vnc -sslGenCert client dilbert x11vnc -sslGenCert client wally x11vnc -sslGenCert client alice ... ``` As usual, follow the prompts if you want to change any of the info field values. As always, it is a good idea (although inconvenient) to protect the private keys with a passphrase. These files are created: ``` ~/.vnc/certs/clients/dilbert.crt ~/.vnc/certs/clients/dilbert.pem ... ``` Note that these are kept in a clients subdirectory. Next, safely copy the .pem files to each corresponding client machine and incorporate them into the VNC viewer / SSL software (see the ideas mentioned above for the CA and server keys). The only difference is these certificates might be referred to as "My Certificates" or "Client Certificates". They are used for client authentication (which is relatively rare for SSL). After copying them you can delete the clients/*.pem files for extra safety because the private keys are not needed by the x11vnc server. You don't really need the clients/*.crt files either (because they have been signed by the CA). But they could come in handy for tracking or troubleshooting, etc. Now start up x11vnc and instruct it to verify connecting clients via SSL and the CA cert: ``` x11vnc -ssl SAVE -sslverify CA ``` The "CA" special token instructs x11vnc to use its CA signed certs for verification. For arbitrary self-signed client certificates (no CA) it might be something like this: ``` x11vnc -ssl SAVE -sslverify path/to/client.crt x11vnc -ssl SAVE -sslverify path/to/client-hash-dir x11vnc -ssl SAVE -sslverify path/to/certs.txt ``` Where client.crt would be an individual client certificate; client-hash-dir a directory of file names based on md5 hashes of the certs (see -sslverify); and certs.txt signifies a single file full of client certificates. Finally, connect with your VNC viewer using the key. Here is an example for the Unix stunnel wrapper script ss_vncviewer: using client authentication (and the standard server authentication with the CA cert): ``` ss_vncviewer -mycert ./dilbert.pem -verify ./cacert.pem far-away.east:0 ``` Our SSVNC enhanced tightvnc viewer can also use these openssl .pem files (you can load them via Certs... -> MyCert dialog). It is also possible to use -sslverify on a per-client key basis, and also using self-signed client keys (x11vnc -sslGenCert client self:dilbert) Now a tricky part is to get Web browsers or Java Runtime to import and use the openssl .pem cert+key files. See the next paragraph on how to convert them to pkcs12 format. If you find a robust way to import them and and get them to use the cert please let us know! Here is how to convert our openssl crt/pem files to pkcs12 format (contains both the client certificate and key) that can be read by Web browsers and Java for use in client authentication: ``` openssl pkcs12 -export -in mycert.crt -inkey mycert.pem -out mycert.p12 ``` it will ask for a passphrase to protect mycert.p12. Some software (e.g. Java ControlPanel) may require a non-empty passphrase. Actually, since our .pem contains both the certificate and private key, you could just supply it for the -in and remove the -inkey option. It appears that for certificates only importing, our .crt file is sufficient and can be read by Mozilla/Firefox and Java... If you have trouble getting your Java Runtime to import and use the cert+key, there is a workaround for the SSL-enabled Java applet. On the Web browser URL that retrieves the VNC applet, simply add a "/?oneTimeKey=..." applet parameter (see ssl-portal for more details on applet parameters; you don't need to do the full portal setup though). The value of the oneTimeKey will be the very long string that is output of the onetimekey program found in the classes/ssl x11vnc directory. Or you can set oneTimeKey=PROMPT in which case the applet will ask you to paste in the long string. These scheme is pretty ugly, but it works. A nice application of it is to make one time keys for users that have already logged into a secure HTTPS site via password. A cgi program then makes a one time key for the logged in user to use: it is passed back over HTTPS as the applet parameter in the URL and so cannot be sniffed. x11vnc is run to use that key via -sslverify. Update: as of Apr 2007 in the 0.9.1 x11vnc tarball there is a new option setting "-users sslpeer=" that will do a switch user much like -unixpw does, but this time using the emailAddress field of the Certificate subject of the verified Client. This mode requires -sslverify turned on to verify the clients via SSL. This mode can be useful in situations using -create or -svc where a new X server needs to be started up as the authenticated user (but unlike in -unixpw mode, the unix username is not obviously known). --- ## Revoking Certificates A large, scaled-up installation may benefit from being able to revoke certificates (e.g. suppose a user's laptop with a vnc client or server key is compromised.) You can use this option with x11vnc: -sslCRL. See the info at that link for a guide on what openssl(1) commands you will need to run to revoke a certificate. --- ## Additional utlities You can get information about your keys via -sslCertInfo. These lists all your keys: ``` x11vnc -sslCertInfo list x11vnc -sslCertInfo ll ``` (the latter is long format). These print long output, including the public certificate, for individual keys: ``` x11vnc -sslCertInfo server x11vnc -sslCertInfo dilbert x11vnc -sslCertInfo all (every key, very long) ``` If you want to add a protecting passphrase to a key originally created without one: ``` x11vnc -sslEncKey SAVE x11vnc -sslEncKey SAVE-fred ``` To delete a cert+key: ``` x11vnc -sslDelCert SAVE x11vnc -sslDelCert SAVE-fred x11vnc -sslDelCert wally ``` (but rm(1) will be just as effective). --- ## Chained Certificates There is increasing interest in using chained CA's instead of a single CA. The merits of using chained CA's are not described here besides to say its use may make some things easier when a certificate needs to be revoked. x11vnc supports chained CA certificates. We describe a basic use case here. Background: Of course the most straight forward way to use SSL with x11vnc is to use no CA at all (see above): a self-signed certificate and key is used and its certificate needs to be safely copied to the client side. This is basically the same as the SSH style of managing keys. Next level up, one can use a single CA to sign server keys: then only the CA's certificate needs to be safely copied to the client side, this can happen even before any server certs are created (again, see all of the discussion above.) With a certificate chain there are two or more CA's involved. Perhaps it looks like this: ``` root_CA ---> intermediate_CA ---> server_cert ``` Where the arrow basically means "signs". In this usage mode the client (viewer-side) will have root_CA's certificate available for verifying (and nothing else.) If the viewer only received server_cert's certificate, it would not have enough info to verify the server. The client needs to have intermediate_CA's cert as well. The way to do this with x11vnc (i.e. an OpenSSL using app) is to concatenate the server_cert's pem and the intermediate_CA's certificate together. For example, suppose the file intermediate_CA.crt had intermediate_CA's certificate. And suppose the file server_cert.pem had the server's certificate and private key pair as described above on this page. We need to do this: ``` cat intermediate_CA.crt >> server_cert.pem ``` (Note: the order of the items inside the file matters; intermediate_CA must be after the server key and cert) and then we run x11vnc like this: ``` x11vnc -ssl ./server_cert.pem ... ``` Then, on the VNC viewer client side, the viewer authenticates the x11vnc server by using root_CA's certificate. Suppose that is in a file named root_CA.crt, then using the SSVNC wrapper script ss_vncviewer (which is also included in the SSVNC package) as our example, we have: ``` ss_vncviewer -verify ./root_CA.crt hostname:0 ``` (where "hostname" is the machine where x11vnc is running.) One could also use the SSVNC GUI setting Certs -> ServerCert to the root_CA.crt file. Any other SSL enabled VNC viewer would use root_CA.crt in a similar way. --- ### Creating Chained Certificates Here is a fun example using VeriSign's "Trial Certificate" program. Note that VeriSign has a Root CA and also an Intermediate CA and uses the latter to sign customers certificates. So this provides an easy way to test out the chained certificates mechanism with x11vnc. First we created a test x11vnc server key: ``` openssl genrsa -out V1.key 1024 ``` then we created a certificate signing request (CSR) for it: ``` openssl req -new -key V1.key -out V1.csr ``` (we followed the prompts and supplied information for the various fields.) Then we went to VeriSign's page http://www.verisign.com/ssl/index.html and clicked on "FREE TRIAL" (the certificate is good for 14 days.) We filled in the forms and got to the point where it asked for the CSR and so we pasted in the contents of the above V1.csr file. Then, after a few more steps, VeriSign signed and emailed us our certificate. The VeriSign Trial certificates were found here: ``` http://www.verisign.com/support/verisign-intermediate-ca/Trial_Secure_Server_Root/index.html http://www.verisign.com/support/verisign-intermediate-ca/trial-secure-server-intermediate/index.html ``` The former was pasted into a file V-Root.crt and the latter was pasted into V-Intermediate.crt We pasted our Trial certificate that VeriSign signed and emailed to us into a file named V1.crt and then we typed: ``` cat V1.key V1.crt > V1.pem cat V1.pem V-Intermediate.crt > V1-combined.pem chmod 600 V1.pem V1-combined.pem ``` So now the file V1-combined.pem has our private key and (VeriSign signed) certificate and VeriSign's Trial Intermediate certificate. Next, we start x11vnc: ``` x11vnc -ssl ./V1-combined.pem ... ``` and finally, on the viewer side (SSVNC wrapper script example): ``` ss_vncviewer -verify ./V-Root.crt hostname:0 ``` One will find that only that combination of certs and keys will work, i.e. allow the SSL connection to be established. Every other combination we tried failed (note that ss_vncviewer uses the external stunnel command to handle the SSL so we are really testing stunnel's SSL implementation on the viewer side); and so the system works as expected. --- ### VNC Client Authentication using Certificate Chains Now, going the other way around with the client authenticating himself via this chain of SSL certificates, x11vnc is run this way: ``` x11vnc -ssl SAVE -sslverify ./V-Root.crt ... ``` (note since the server must always supply a cert, we use its normal self-signed, etc., one via "-ssl SAVE" and use the VeriSign root cert for client authentication via -sslverify. The viewer must now supply the combined certificates, e.g.: ``` ss_vncviewer -mycert ./V1-combined.pem hostname:0 ``` --- ### Using OpenSSL and x11vnc to create Certificate Chains Although the x11vnc CA mechanism (-sslGenCA and -sslGenCert; see above) was designed to only handle a single root CA (to sign server and/or client certs) it can be coerced into creating a certificate chain by way of an extra openssl(1) command. We will first create two CA's via -sslGenCA; then use one of these CA to sign the other; create a new (non-CA) server cert; and append the intermediate CA's cert to the server cert to have everything needed in the one file. Here are the commands we ran to do what the previous paragraph outlines. First we create the two CA's, called CA_root and CA_Intermediate here, in separate directories via x11vnc: ``` x11vnc -ssldir ~/CA_Root -sslGenCA (follow the prompts, we included "CA_Root", e.g. Common Name, to aid identifying it) ``` ``` x11vnc -ssldir ~/CA_Intermediate -sslGenCA (follow the prompts, we included "CA_Intermediate", e.g. Common Name, to aid identifying it) ``` Next backup CA_Intermediate's cert and then sign it with CA_Root: ``` mv ~/CA_Intermediate/CA/cacert.pem ~/CA_Intermediate/CA/cacert.pem.ORIG cd ~/CA_Root openssl ca -config ./CA/ssl.cnf -policy policy_anything -extensions v3_ca -notext -ss_cert ~/CA_Intermediate/CA/cacert.pem.ORIG -out ~/CA_Intermediate/CA/cacert.pem ``` Note that it is required to cd to the ~/CA_Root directory and run the openssl command from there. You can print out info about the cert you just modified by: ``` openssl x509 -noout -text -in ~/CA_Intermediate/CA/cacert.pem ``` Now we create an x11vnc server cert named "test_chain" that is signed by CA_Intermediate: ``` x11vnc -ssldir ~/CA_Intermediate -sslGenCert server test_chain (follow the prompts) ``` You can print out information about this server cert just created via this command: ``` x11vnc -ssldir ~/CA_Intermediate -sslCertInfo SAVE-test_chain ``` This will tell you the full path to the server certificate, which is needed because we need to manually append the CA_Intermediate cert for the chain to work: ``` cat ~/CA_Intermediate/CA/cacert.pem >> ~/CA_Intermediate/server-test_chain.pem ``` Now we are finally ready to use it. We can run x11vnc using this server cert+key by either this command: ``` x11vnc -ssldir ~/CA_Intermediate -ssl SAVE-test_chain ... ``` or this command: ``` x11vnc -ssl ~/CA_Intermediate/server-test_chain.pem ... ``` since they are equivalent (both load the same pem file.) Finally we connect via VNC viewer that uses CA_Root to verify the server. As before we use ss_vncviewer: ``` ss_vncviewer -verify ~/CA_Root/CA/cacert.pem hostname:0 ``` Client Certificates (see above) work in a similar manner. So although it is a little awkward with the extra steps (e.g. appending the CA_Intermediate cert) it is possible. If you want to do this entirely with openssl(1) you will have to learn the openssl commands corresponding to -genCA and -genCert. You may be able to find guides on the Internet to do this. Starting with x11vnc 0.9.10, you can have it print out the wrapper scripts it uses via: -sslScripts (you will still need to fill in a few pieces of information; ask if it is not clear from the source code.) --- ## More info See also this article for some some general info and examples using stunnel and openssl on Windows with VNC. Also http://www.stunnel.org/faq/certs.html is a very good source of information on SSL certificate creation and management. x11vnc-0.9.17/doc/SSVNC.md000066400000000000000000001361071500463450600147260ustar00rootroot00000000000000# Enhanced TightVNC Viewer (SSVNC: SSL/SSH VNC viewer) The Enhanced TightVNC Viewer, SSVNC, adds encryption security to VNC connections. The package provides a GUI for Windows, Mac OS X, and Unix that automatically starts up an STUNNEL SSL tunnel for SSL or ssh/plink for SSH connections to any VNC server, such as x11vnc, and then launches the VNC Viewer to use the encrypted tunnel. The x11vnc server has built-in SSL support, however SSVNC can make SSL encrypted VNC connections to any VNC Server if they are running an SSL tunnel, such as STUNNEL or socat, at their end. SSVNC's SSH tunnel will work to any VNC Server host running sshd that you can log into. The Enhanced TightVNC Viewer package started as a project to add some patches to the long neglected Unix TightVNC Viewer. However, now the front-end GUI, encryption, and wrapper scripts features possibly outweigh the Unix TightVNC Viewer improvements (see the lists below to compare). The SSVNC Unix vncviewer can also be run without the SSVNC encryption GUI as an enhanced replacement for the xvncviewer, xtightvncviewer, etc., viewers. In addition to normal SSL, SSVNC also supports the VeNCrypt SSL/TLS and Vino/ANONTLS encryption extensions to VNC on Unix, Mac OS X, and Windows. Via the provided SSVNC VeNCrypt bridge, VeNCrypt and ANONTLS encryption also works with any third party VNC Viewer (e.g. RealVNC, TightVNC, UltraVNC, etc...) you select via 'Change VNC Viewer'. The short name for this project is "ssvnc" for SSL/SSH VNC Viewer. This is the name of the command to start it. There is a simplified SSH-Only mode (sshvnc). And an even more simplified Terminal-Services mode (tsvnc) for use with x11vnc on the remote side. The tool has many additional features; see the descriptions below. It is a self-contained bundle, you could carry it around on, say, a USB memory stick / flash drive for secure VNC viewing from almost any machine, Unix, Mac OS X, and Windows (and if you create a directory named "Home" in the toplevel ssvnc directory on the drive your VNC profiles and certs will be kept there as well). For Unix, there is also a conventional source tarball to build and install in the normal way and not use a pre-built bundle. --- ## Announcements Important: If you created any SSL certificates with SSVNC (or anything else) on a Debian or Ubuntu system from Sept. 2006 through May 2008, then those keys are likely extremely weak and can be easily cracked. The certificate files should be deleted and recreated on a non-Debian system or an updated one. See http://www.debian.org/security/2008/dsa-1571 for details. The same applies to SSH keys. Please read this information on using SSVNC on workstations with Untrusted Local Users. --- ## Feature List Wrapper scripts and a tcl/tk GUI were written to create these features for Unix, Mac OS X, and Windows: * SSL support for connections using the bundled stunnel program. * Automatic SSH connections from the GUI (system ssh is used on Unix and MacOS X; bundled plink is used on Windows) * Ability to Save and Load VNC profiles for different hosts. * You can also use your own VNC Viewer, e.g. UltraVNC or RealVNC, with the SSVNC encryption GUI front-end if you prefer. * Create or Import SSL Certificates and Private Keys. * Reverse (viewer listening) VNC connections via SSL and SSH. * VeNCrypt SSL/TLS VNC encryption support (used by VeNCrypt, QEMU, ggi, libvirt/virt-manager/xen, vinagre/gvncviewer/gtk-vnc) * ANONTLS SSL/TLS VNC encryption support (used by Vino) * VeNCrypt and ANONTLS are also enabled for any 3rd party VNC Viewer (e.g. RealVNC, TightVNC, UltraVNC ...) on Unix, MacOSX, and Windows via the provided SSVNC VeNCrypt Viewer Bridge tool (use 'Change VNC Viewer' to select the one you want.) * Support for Web Proxies, SOCKS Proxies, and the UltraVNC repeater proxy (e.g. repeater://host:port+ID:1234). Multiple proxies may be chained together (3 max). * Support for SSH Gateway connections and non-standard SSH ports. * Automatic Service tunnelling via SSH for CUPS and SMB Printing, ESD/ARTSD Audio, and SMB (Windows/Samba) filesystem mounting. * Sets up any additional SSH port redirections that you want. * Zeroconf (aka Bonjour) is used on Unix and Mac OS X to find VNC servers on your local network if the avahi-browse or dns-sd program is available and in your PATH. * Port Knocking for "closed port" SSH/SSL connections. In addition to a simple fixed port sequence and one-time-pad implementation, a hook is also provided to run any port knocking client before connecting. * Support for native MacOS X usage with bundled Chicken of the VNC viewer (the Unix X11 viewer is also provided for MacOS X, and is better IMHO. It is now the default on MacOS X.) * Dynamic VNC Server Port determination and redirection (using ssh's builtin SOCKS proxy, ssh -D) for servers like x11vnc that print out PORT= at startup. * Unix Username and Password entry for use with "x11vnc -unixpw" type login dialogs. * Simplified mode launched by command "sshvnc" that is SSH Only. * Simplified mode launched by command "tsvnc" that provides a VNC "Terminal Services" mode (uses x11vnc on the remote side). * IPv6 support for all connection modes on Unix, MacOSX, and Windows. Patches to TightVNC 1.3.9 vnc_unixsrc tree were created for Unix TightVNC Viewer improvements (these only apply to the Unix VNC viewer, including MacOSX XQuartz): * rfbNewFBSize VNC support (dynamic screen resizing) * Client-side Scaling of the Desktop in the viewer. * ZRLE VNC encoding support (RealVNC's encoding) * Support for the ZYWRLE encoding, a wavelet based extension to ZRLE to improve compression of motion video and photo regions. * TurboVNC support (VirtualGL's modified TightVNC encoding; requires TurboJPEG library) * Pipelined Updates of the framebuffer as in TurboVNC (asks for the next update before the current one has finished downloading; this gives some speedup on high latency connections.) * Cursor alphablending with x11vnc at 32bpp (-alpha option) * Option "-unixpw ..." for use with "x11vnc -unixpw" type login dialogs. * Support for UltraVNC extensions: 1/n Server side scaling, Text Chat, Single Window, Disable Server-side Input. Both UltraVNC and x11vnc servers support these extensions. * UltraVNC File Transfer via an auxiliary Java helper program (java must be in $PATH). Note that the x11vnc server also supports UltraVNC file transfer. * Connection support for the UltraVNC repeater proxy (-repeater option). * Support for UltraVNC Single Click operation. (both unencrypted: SC I, and SSL encrypted: SC III) * Support for UltraVNC DSM Encryption Plugin symmetric encryption mode. (ARC4, AESV2, MSRC4, and SecureVNC) * Support for UltraVNC MS-Logon authentication (NOTE: the UltraVNC MS-Logon key exchange implementation is very weak; an eavesdropper on the network can recover your Windows password easily in a few seconds; you need to use an additional encrypted tunnel with MS-Logon.) * Support for symmetric encryption (including blowfish and 3des ciphers) to Non-UltraVNC Servers. Any server using the same encryption method will work, e.g.: x11vnc -enc blowfish:./my.key * Instead of hostname:display one can also supply "exec=command args..." to connect the viewer to the stdio of an external command (e.g. stunnel or socat) rather than using a TCP/IP socket. Unix domain sockets, e.g. /path/to/unix/socket, and a previously opened file descriptor fd=0, work too. * Local Port Protections for STUNNEL and SSH: avoid having for long periods of time a listening port on the the local (VNC viewer) side that redirects to the remote side. * Reverse (viewer listening) VNC connections can show a Popup dialog asking whether to accept the connection or not (-acceptpopup.) The extra info provided by UltraVNC Single Click reverse connections is also supported (-acceptpopupsc) * Extremely low color modes: 64 and 8 colors in 8bpp (-use64/-bgr222, -use8/-bgr111) * Medium color mode: 16bpp mode on a 32bpp Viewer display (-16bpp/-bgr565) * For use with x11vnc's client-side caching -ncache method use the cropping option -ycrop n. This will "hide" the large pixel buffer cache below the actual display. Set to the actual height or use -1 for autodetection (also, tall screens, H > 2*W, are autodetected by default). * Escape Keys: specify a set of modifier keys so that when they are all pressed down you can invoke Popup menu actions via keystrokes. I.e., a set of 'Hot Keys'. One can also pan (move) the desktop inside the viewport via Arrow keys or a mouse drag. * Scrollbar width setting: -sbwidth n, the default is very thin, 2 pixels, for less distracting -ycrop usage. * Selection text sending and receiving can be fine-tuned with the -sendclipboard, -sendalways, and -recvtext options. * TightVNC compression and quality levels are automatically set based on observed network latency (n.b. not bandwidth.) * Improvements to the Popup menu, all of these can now be changed dynamically via the menu: ViewOnly, Toggle Bell, CursorShape updates, X11 Cursor, Cursor Alphablending, Toggle Tight/ZRLE, Toggle JPEG, FullColor/16bpp/8bpp (256/64/8 colors), Greyscale for low color modes, Scaling the Viewer resolution, Escape Keys, Pipeline Updates, and others, including UltraVNC extensions. * Maintains its own BackingStore if the X server does not. * The default for localhost:0 connections is not raw encoding since same-machine connections are pretty rare. Default assumes you are using a SSL or SSH tunnel. Use -rawlocal to revert. * XGrabServer support for fullscreen mode, for old window managers (-grab/-graball option). * Fix for Popup menu positioning for old window managers (-popupfix option). * The VNC Viewer ssvncviewer supports IPv6 natively (no helpers needed.) The list of 3rd party software bundled in the archive files: * TightVNC Viewer (windows, unix, macosx) * Chicken of the VNC Viewer (macosx) * Stunnel (windows, unix, macosx) * Putty/Plink/Pageant (windows) * OpenSSL (windows) * esound (windows) These are all self-contained in the bundle directory: they will not be installed on your system. Just un-zip or un-tar the file you downloaded and run the frontend ssvnc straight from its directory. Alternatively, on Unix you can use the conventional source tarball. --- ## Here is the Quick Start info from the README for how to setup and use SSVNC: ``` Quick Start: ----------- Unix and Mac OS X: Inside a Terminal do something like the following. Unpack the archive: % gzip -dc ssvnc-1.0.29.tar.gz | tar xvf - Run the GUI: % ./ssvnc/Unix/ssvnc (for Unix) % ./ssvnc/MacOSX/ssvnc (for Mac OS X) The smaller file "ssvnc_no_windows-1.0.29.tar.gz" could have been used as well. On MacOSX you could also click on the SSVNC app icon in the Finder. On MacOSX if you don't like the Chicken of the VNC (e.g. no local cursors, no screen size rescaling, and no password prompting), and you have the XDarwin X server installed, you can set DISPLAY before starting ssvnc (or type DISPLAY=... in Host:Disp and hit Return). Then our enhanced TightVNC viewer will be used instead of COTVNC. Update: there is now a 'Use X11 vncviewer on MacOSX' under Options ... If you want a SSH-only tool (without the distractions of SSL) run the command: sshvnc instead of "ssvnc". Or click "SSH-Only Mode" under Options. Control-h will toggle between the two modes. If you want a simple VNC Terminal Services only mode (requires x11vnc on the remote server) run the command: tsvnc instead of "ssvnc". Or click "Terminal Services" under Options. Control-t will toggle between the two modes. "tsvnc profile-name" and "tsvnc user@hostname" work too. Unix/MacOSX Install: There is no standard install for the bundles, but you can make symlinks like so: cd /a/directory/in/PATH ln -s /path/to/ssvnc/bin/{s,t}* . Or put /path/to/ssvnc/bin, /path/to/ssvnc/Unix, or /path/to/ssvnc/MacOSX in your PATH. For the conventional source tarball it will compile and install, e.g.: gzip -dc ssvnc-1.0.29.src.tar.gz | tar xvf - cd ssvnc-1.0.29 make config make all make PREFIX=/my/install/dir install then have /my/install/dir/bin in your PATH. Windows: Unzip, using WinZip or a similar utility, the zip file: ssvnc-1.0.29.zip Run the GUI, e.g.: Start -> Run -> Browse and then navigate to .../ssvnc/Windows/ssvnc.exe select Open, and then OK to launch it. The smaller file "ssvnc_windows_only-1.0.29.zip" could have been used as well. You can make a Windows shortcut to this program if you want to. See the Windows/README.txt for more info. If you want a SSH-only tool (without the distractions of SSL) run the command: sshvnc.bat Or click "SSH-Only Mode" under Options. If you want a simple VNC Terminal Services only mode (requires x11vnc on the remote server) run the command: tsvnc.bat Or click "Terminal Services" under Options. Control-t will toggle between the two modes. "tsvnc profile-name" and "tsvnc user@hostname" work too. ``` --- You can read all of the SSVNC GUI's Online Help Text here. --- The bundle unpacks a directory/folder named: ssvnc. It contains these programs to launch the GUI: ``` Windows/ssvnc.exe for Windows MacOSX/ssvnc for Mac OS X Unix/ssvnc for Unix ``` (the Mac OS X and Unix launchers are simply links to the bin directory). See the README for more information. The SSH-Only mode launcher program has name sshvnc. The Terminal Services mode launcher program (assumes x11vnc 0.8.4 or later and Xvfb installed on the server machine) has name tsvnc. The Viewer SSL support is done via a wrapper script (bin/ssvnc_cmd that calls bin/util/ss_vncviewer) that starts up the STUNNEL tunnel first and then starts the TightVNC viewer pointed at that tunnel. The bin/ssvnc program is a GUI front-end to that script. See this FAQ for more details on SSL tunnelling. In SSH connection mode, the wrappers start up SSH appropriately. ## Memory Stick Usage If you create a directory named "Home" in that toplevel ssvnc directory then that will be used as the base for storing VNC profiles and certificates. Also, for convenience, if you first run the command with "." as an argument (e.g. "ssvnc .") it will automatically create the "Home" directory for you. This is handy if you want to place SSVNC on a USB flash drive that you carry around for mobile use and you want the profiles you create to stay with the drive (otherwise you'd have to browse to the drive directory each time you load or save). One user on Windows created a BAT file to launch SSVNC and needed to do this to get the Home directory correct: ``` cd \ssvnc\Windows start \ssvnc\Windows\ssvnc.exe ``` (an optional profile name can be supplied to the ssvnc.exe line) WARNING: if you use ssvnc from an "Internet Cafe", i.e. some untrusted computer, please be aware that someone may have set up that machine to be capturing your keystrokes, etc. ## SSH-Only version The command "sshvnc" can be run instead of "ssvnc" to get an SSH-only version of the tool: [sshvnc.gif] These also work: "sshvnc myprofile" and "sshvnc user@hostname". To switch from the regular SSVNC mode, click "SSH-Only Mode" under Options. This mode is less distracting if you never plan to use SSL, manage certificates, etc. Terminal Services Only: The command "tsvnc" can be run instead of "ssvnc" to get a "Terminal Services" only version of the tool: [tsvnc.gif] These also work: "tsvnc myprofile" and "tsvnc user@hostname". To switch from the regular SSVNC mode, click "Terminal Services" under Options. This mode requires x11vnc (0.9.3 or later) installed on the remote machine to find, create, and manage the user sessions. SSH is used to create the encrypted and authenticated tunnel. The Xvfb (virtual framebuffer X server) program must also be installed on the remote system. However tsvnc will also connect to a real X session (i.e. on the physical hardware) if you are already logged into the X session; this is a useful access mode and does not require Xvfb on the remote system. This mode should be very easy for beginner users to understand and use. On the remote end you only need to have x11vnc and Xvfb available in $PATH, and on the local end you just run something like: tsvnc myname@myhost.com (or start up the tsvnc GUI first and then enter myname@myhost.com and press "Connect"). Normally the Terminal Services sessions created are virtual (RAM-only) ones (e.g. Xvfb, Xdummy, or Xvnc), however a nice feature is if you have a regular X session (i.e displaying on the physical hardware) on the remote machine that you are ALREADY logged into, then the x11vnc run from tsvnc will find it for you as well. Also, there is setting "X Login" under Advanced Options that allows you to attach to a real X server with no one logged in yet (i.e. XDM/GDM/KDM Login Greeter screen) as long as you have sudo(1) permission on the remote machine. Nice features to soon to be added to the tsvnc mode are easy CUPS printing (working fairly well) and Sound redirection (needs much work) of the Terminal Services Desktop session. It is easier in tsvnc mode because the entire desktop session can be started with the correct environment. ssvnc tries to handle the general case of an already started desktop and that is more difficult. ## Proxies Web proxies, SOCKS proxies, and the UltraVNC repeater proxy are supported to allow the SSVNC connection to go through the proxy to the otherwise unreachable VNC Server. SSH gateway machines can be used in the same way. Read more about SSVNC proxy support here. ## Dynamic VNC Server Port determination If you are running SSVNC on Unix and are using SSH to start the remote VNC server and the VNC server prints out the line "PORT=NNNN" to indicate which dynamic port it is using (x11vnc does this), then if you prefix the SSH command with "PORT=" SSVNC will watch for the PORT=NNNN line and uses ssh's built in SOCKS proxy (ssh -D ...) to connect to the dynamic VNC server port through the SSH tunnel. For example: ``` VNC Host:Display user@somehost.com Remote SSH Command: PORT= x11vnc -find ``` or "PORT= x11vnc -display :0 -localhost", etc. Or use "P= x11vnc ..." There is also code to detect the display of the regular Unix vncserver(1). It extracts the display (and hence port) from the lines "New 'X' desktop is hostname:4" and also "VNC server is already running as :4". So you can use something like: ``` PORT= vncserver; sleep 15 or: PORT= vncserver :4; sleep 15 ``` the latter is preferred because when you reconnect with it will find the already running one. The former one will keep creating new X sessions if called repeatedly. If you use PORT= on Windows, a large random port is selected instead and the -rfbport option is passed to x11vnc (it does not work with vncserver). ## Patches for Unix Tightvnc viewer The rfbNewFBSize support allows the enhanced TightVNC Unix viewer to resize when the server does (e.g. "x11vnc -R scale=3/4" remote control command). The cursor alphablending is described here. The RealVNC ZRLE encoding is supported, in addition to some low colors modes (16bpp and 8bpp at 256, 64, and even 8 colors, for use on very slow connections). Greyscales are also enabled for the low color modes. The Popup menu (F8) is enhanced with the ability to change many things on the fly. F9 is added as a shortcut to toggle FullScreen mode. ## Client Side Caching The x11vnc client-side caching is handled nicely by this viewer. The very large pixel cache below the actual display in this caching method is distracting. Our Unix VNC viewer will automatically try to autodetect the actual display height if the framebuffer is very tall (more than twice as high as it is wide). One can also set the height to the known value via -ycrop n, or use -ycrop -1 to force autodection. In fullscreen mode one is not possible to scroll down to the pixel cache region. In non-fullscreen mode the window manager frame is "shrink-wrapped" around the actual screen display. You can still scroll down to the pixel cache region. The scrollbars are set to be very thin (2 pixels) to be less distracting. Use the -sbwidth n to make them wider. Probably nobody is interested in the grabserver patch for old window managers when the viewer is in fullscreen mode... This and some other unfixed bugs have been fixed in our patches (fullscreen toggle works with KDE, -x11cursor has been fixed, and the dot cursor has been made smaller). From the -help output: ``` SSVNC Viewer (based on TightVNC viewer version 1.3.9) Usage: vncviewer [] [][:] vncviewer [] [][::] vncviewer [] exec=[CMD ARGS...] vncviewer [] fd=n vncviewer [] /path/to/unix/socket vncviewer [] -listen [] vncviewer -help are standard Xt options, or: -via -shared (set by default) -noshared -viewonly -fullscreen -noraiseonbeep -passwd (standard VNC authentication) -user (Unix login authentication) -encodings (e.g. "tight,copyrect") -bgr233 -owncmap -truecolour -depth -compresslevel (0..9: 0-fast, 9-best) -quality (0..9: 0-low, 9-high) -nojpeg -nocursorshape -x11cursor -autopass Option names may be abbreviated, e.g. -bgr instead of -bgr233. See the manual page for more information. Enhanced TightVNC viewer (SSVNC) options: URL http://www.karlrunge.com/x11vnc/ssvnc.html Note: ZRLE and ZYWRLE encodings are now supported. Note: F9 is shortcut to Toggle FullScreen mode. Note: In -listen mode set the env var. SSVNC_MULTIPLE_LISTEN=1 to allow more than one incoming VNC server at a time. This is the same as -multilisten described below. Set SSVNC_MULTIPLE_LISTEN=MAX:n to allow no more than "n" simultaneous reverse connections. Note: If the host:port is specified as "exec=command args..." then instead of making a TCP/IP socket connection to the remote VNC server, "command args..." is executed and the viewer is attached to its stdio. This enables tunnelling established via an external command, e.g. an stunnel(8) that does not involve a listening socket. This mode does not work for -listen reverse connections. If the host:port is specified as "fd=n" then it is assumed n is an already opened file descriptor to the socket. (i.e the parent did fork+exec) If the host:port contains a '/' it is interpreted as a unix-domain socket (AF_LOCAL insead of AF_INET) -multilisten As in -listen (reverse connection listening) except allow more than one incoming VNC server to be connected at a time. The default for -listen of only one at a time tries to play it safe by not allowing anyone on the network to put (many) desktops on your screen over a long window of time. Use -multilisten for no limit. -acceptpopup In -listen (reverse connection listening) mode when a reverse VNC connection comes in show a popup asking whether to Accept or Reject the connection. The IP address of the connecting host is shown. Same as setting the env. var. SSVNC_ACCEPT_POPUP=1. -acceptpopupsc As in -acceptpopup except assume UltraVNC Single Click (SC) server. Retrieve User and ComputerName info from UltraVNC Server and display in the Popup. -use64 In -bgr233 mode, use 64 colors instead of 256. -bgr222 Same as -use64. -use8 In -bgr233 mode, use 8 colors instead of 256. -bgr111 Same as -use8. -16bpp If the vnc viewer X display is depth 24 at 32bpp request a 16bpp format from the VNC server to cut network traffic by up to 2X, then tranlate the pixels to 32bpp locally. -bgr565 Same as -16bpp. -grey Use a grey scale for the 16- and 8-bpp modes. -alpha Use alphablending transparency for local cursors requires: x11vnc server, both client and server must be 32bpp and same endianness. -scale str Scale the desktop locally. The string "str" can a floating point ratio, e.g. "0.9", or a fraction, e.g. "3/4", or WxH, e.g. 1280x1024. Use "fit" to fit in the current screen size. Use "auto" to fit in the window size. "str" can also be set by the env. var. SSVNC_SCALE. If you observe mouse trail painting errors, enable X11 Cursor mode (either via Popup or -x11cursor.) Note that scaling is done in software and so can be slow and requires more memory. Some speedup Tips: ZRLE is faster than Tight in this mode. When scaling is first detected, the encoding will be automatically switched to ZRLE. Use the Popup menu if you want to go back to Tight. Set SSVNC_PRESERVE_ENCODING=1 to disable this. Use a solid background on the remote side. (e.g. manually or via x11vnc -solid ...) If the remote server is x11vnc, try client side caching: x11vnc -ncache 10 ... -ycrop n Only show the top n rows of the framebuffer. For use with x11vnc -ncache client caching option to help "hide" the pixel cache region. Use a negative value (e.g. -1) for autodetection. Autodetection will always take place if the remote fb height is more than 2 times the width. -sbwidth n Scrollbar width for x11vnc -ncache mode (-ycrop), default is very narrow: 2 pixels, it is narrow to avoid distraction in -ycrop mode. -nobell Disable bell. -rawlocal Prefer raw encoding for localhost, default is no, i.e. assumes you have a SSH tunnel instead. -notty Try to avoid using the terminal for interactive responses: use windows for messages and prompting instead. Messages will also be printed to terminal. -sendclipboard Send the X CLIPBOARD selection (i.e. Ctrl+C, Ctrl+V) instead of the X PRIMARY selection (mouse select and middle button paste.) -sendalways Whenever the mouse enters the VNC viewer main window, send the selection to the VNC server even if it has not changed. This is like the Xt resource translation SelectionToVNC(always) -recvtext str When cut text is received from the VNC server, ssvncviewer will set both the X PRIMARY and the X CLIPBOARD local selections. To control which is set, specify 'str' as 'primary', 'clipboard', or 'both' (the default.) -graball Grab the entire X server when in fullscreen mode, needed by some old window managers like fvwm2. -popupfix Warp the popup back to the pointer position, needed by some old window managers like fvwm2. -sendclipboard Send the X CLIPBOARD selection (i.e. Ctrl+C, Ctrl+V) instead of the X PRIMARY selection (mouse select and middle button paste.) -sendalways Whenever the mouse enters the VNC viewer main window, send the selection to the VNC server even if it has not changed. This is like the Xt resource translation SelectionToVNC(always) -recvtext str When cut text is received from the VNC server, ssvncviewer will set both the X PRIMARY and the X CLIPBOARD local selections. To control which is set, specify 'str' as 'primary', 'clipboard', or 'both' (the default.) -graball Grab the entire X server when in fullscreen mode, needed by some old window managers like fvwm2. -popupfix Warp the popup back to the pointer position, needed by some old window managers like fvwm2. -grabkbd Grab the X keyboard when in fullscreen mode, needed by some window managers. Same as -grabkeyboard. -grabkbd is the default, use -nograbkbd to disable. -bs, -nobs Whether or not to use X server Backingstore for the main viewer window. The default is to not, mainly because most Linux, etc, systems X servers disable *all* Backingstore by default. To re-enable it put Option "Backingstore" in the Device section of /etc/X11/xorg.conf. In -bs mode with no X server backingstore, whenever an area of the screen is re-exposed it must go out to the VNC server to retrieve the pixels. This is too slow. In -nobs mode, memory is allocated by the viewer to provide its own backing of the main viewer window. This actually makes some activities faster (changes in large regions) but can appear to "flash" too much. -noshm Disable use of MIT shared memory extension (not recommended) -termchat Do the UltraVNC chat in the terminal vncviewer is in instead of in an independent window. -unixpw str Useful for logging into x11vnc in -unixpw mode. "str" is a string that allows many ways to enter the Unix Username and Unix Password. These characters: username, newline, password, newline are sent to the VNC server after any VNC authentication has taken place. Under x11vnc they are used for the -unixpw login. Other VNC servers could do something similar. You can also indicate "str" via the environment variable SSVNC_UNIXPW. Note that the Escape key is actually sent first to tell x11vnc to not echo the Unix Username back to the VNC viewer. Set SSVNC_UNIXPW_NOESC=1 to override this. If str is ".", then you are prompted at the command line for the username and password in the normal way. If str is "-" the stdin is read via getpass(3) for username@password. Otherwise if str is a file, it is opened and the first line read is taken as the Unix username and the 2nd as the password. If str prefixed by "rm:" the file is removed after reading. Otherwise, if str has a "@" character, it is taken as username@password. Otherwise, the program exits with an error. Got all that? -repeater str This is for use with UltraVNC repeater proxy described here: http://www.uvnc.com/addons/repeater.html. The "str" is the ID string to be sent to the repeater. E.g. ID:1234 It can also be the hostname and port or display of the VNC server, e.g. 12.34.56.78:0 or snoopy.com:1. Note that when using -repeater, the host:dpy on the cmdline is the repeater server, NOT the VNC server. The repeater will connect you. Example: vncviewer ... -repeater ID:3333 repeat.host:5900 Example: vncviewer ... -repeater vhost:0 repeat.host:5900 Use, e.g., '-repeater SCIII=ID:3210' if the repeater is a Single Click III (SSL) repeater (repeater_SSL.exe) and you are passing the SSL part of the connection through stunnel, socat, etc. This way the magic UltraVNC string 'testB' needed to work with the repeater is sent to it. -rfbversion str Set the advertised RFB version. E.g.: -rfbversion 3.6 For some servers, e.g. UltraVNC this needs to be done. -ultradsm UltraVNC has symmetric private key encryption DSM plugins: http://www.uvnc.com/features/encryption.html. It is assumed you are using a unix program (e.g. our ultravnc_dsm_helper) to encrypt and decrypt the UltraVNC DSM stream. IN ADDITION TO THAT supply -ultradsm to tell THIS viewer to modify the RFB data sent so as to work with the UltraVNC Server. For some reason, each RFB msg type must be sent twice under DSM. -mslogon user Use Windows MS Logon to an UltraVNC server. Supply the username or "1" to be prompted. The default is to autodetect the UltraVNC MS Logon server and prompt for the username and password. IMPORTANT NOTE: The UltraVNC MS-Logon Diffie-Hellman exchange is very weak and can be brute forced to recover your username and password in a few seconds of CPU time. To be safe, be sure to use an additional encrypted tunnel (e.g. SSL or SSH) for the entire VNC session. -chatonly Try to be a client that only does UltraVNC text chat. This mode is used by x11vnc to present a chat window on the physical X11 console (i.e. chat with the person at the display). -env VAR=VALUE To save writing a shell script to set environment variables, specify as many as you need on the command line. For example, -env SSVNC_MULTIPLE_LISTEN=MAX:5 -env EDITOR=vi -noipv6 Disable all IPv6 sockets. Same as VNCVIEWER_NO_IPV6=1. -noipv4 Disable all IPv4 sockets. Same as VNCVIEWER_NO_IPV4=1. -printres Print out the Ssvnc X resources (appdefaults) and then exit You can save them to a file and customize them (e.g. the keybindings and Popup menu) Then point to the file via XENVIRONMENT or XAPPLRESDIR. -pipeline Like TurboVNC, request the next framebuffer update as soon as possible instead of waiting until the end of the current framebuffer update coming in. Helps 'pipeline' the updates. This is currently the default, use -nopipeline to disable. -appshare Enable features for use with x11vnc's -appshare mode where instead of sharing the full desktop only the application's windows are shared. Viewer multilisten mode is used to create the multiple windows: -multilisten is implied. See 'x11vnc -appshare -help' more information on the mode. Features enabled in the viewer under -appshare are: Minimum extra text in the title, auto -ycrop is disabled, x11vnc -remote_prefix X11VNC_APPSHARE_CMD: message channel, x11vnc initial window position hints. See also Escape Keys below for additional key and mouse bindings. -escape str This sets the 'Escape Keys' modifier sequence and enables escape keys mode. When the modifier keys escape sequence is held down, the next keystroke is interpreted locally to perform a special action instead of being sent to the remote VNC server. Use '-escape default' for the default modifier sequence. (Unix: Alt_L,Super_L and MacOSX: Control_L,Meta_L) Here are the 'Escape Keys: Help+Set' instructions from the Popup Menu: Escape Keys: Enter a comma separated list of modifier keys to be the 'escape sequence'. When these keys are held down, the next keystroke is interpreted locally to invoke a special action instead of being sent to the remote VNC server. In other words, a set of 'Hot Keys'. To enable or disable this, click on 'Escape Keys: Toggle' in the Popup. Here is the list of hot-key mappings to special actions: r: refresh desktop b: toggle bell c: toggle full-color f: file transfer x: x11cursor z: toggle Tight/ZRLE l: full screen g: graball e: escape keys dialog s: scale dialog +: scale up (=) -: scale down (_) t: text chat a: alphablend cursor V: toggle viewonly Q: quit viewer 1 2 3 4 5 6: UltraVNC scale 1/n Arrow keys: pan the viewport about 10% for each keypress. PageUp / PageDown: pan the viewport by a screenful vertically. Home / End: pan the viewport by a screenful horizontally. KeyPad Arrow keys: pan the viewport by 1 pixel for each keypress. Dragging the Mouse with Button1 pressed also pans the viewport. Clicking Mouse Button3 brings up the Popup Menu. The above mappings are *always* active in ViewOnly mode, unless you set the Escape Keys value to 'never'. If the Escape Keys value below is set to 'default' then a default list of of modifier keys is used. For Unix it is: Alt_L,Super_L and for MacOSX it is Control_L,Meta_L. Note: the Super_L key usually has a Windows(TM) Flag on it. Also note the _L and _R mean the key is on the LEFT or RIGHT side of the keyboard. On Unix the default is Alt and Windows keys on Left side of keyboard. On MacOSX the default is Control and Command keys on Left side of keyboard. Example: Press and hold the Alt and Windows keys on the LEFT side of the keyboard and then press 'c' to toggle the full-color state. Or press 't' to toggle the ultravnc Text Chat window, etc. To use something besides the default, supply a comma separated list (or a single one) from: Shift_L Shift_R Control_L Control_R Alt_L Alt_R Meta_L Meta_R Super_L Super_R Hyper_L Hyper_R or Mode_switch.

Both are bundled in the package for your convenience. The GUI has other useful features. When the connection is finished, you will be asked if you want to terminate the STUNNEL program. For SSH connections from Windows the GUI will use PLINK instead of STUNNEL. ## Unix and Mac OS X Run the GUI (ssvnc, see above) and let me know how it goes. --- Hopefully this tool will make it convenient for people to help test and use the built-in SSL support in x11vnc. Extra testing of this feature is much appreciated!! Thanks. Please Help Test the newly added features: * Automatic Service tunnelling via SSH for CUPS and SMB Printing * ESD/ARTSD Audio * SMB (Windows/Samba) filesystem mounting These allow you to print from the remote (VNC Server) machine to local printers, listen to sounds (with some limitations) from the remote VNC Server machine, and to mount your local Windows or Samba shares on the remote VNC Server machine. Basically these new features try to automate the tricks described here: * http://www.karlrunge.com/x11vnc/faq.html#faq-smb-shares * http://www.karlrunge.com/x11vnc/faq.html#faq-cups * http://www.karlrunge.com/x11vnc/faq.html#faq-sound --- ## Downloading Downloads for this project are hosted at Sourceforge.net.

Let us know how it went. Current Unix binaries in the archives: ``` Linux.i686 Linux.x86_64 Linux.ppc64 X (removed) Linux.alpha X (removed) SunOS.sun4u SunOS.sun4m SunOS.i86pc Darwin.Power.Macintosh Darwin.i386 HP-UX.9000 X (removed) FreeBSD.i386 X (removed) NetBSD.i386 X (removed) OpenBSD.i386 X (removed) ``` (some of these are out of date, marked with 'X' above, because I no longer have access to machines running those OS's. Use the "build.unix" script to recompile on your system). Note: some of the above binaries depend on libssl.so.0.9.7, whereas some recent distros only provide libssl.so.0.9.8 by default (for compatibility reasons they should install both by default but not all do). So you may need to instruct your distro to install the 0.9.7 library (it is fine to have both runtimes installed simultaneously since the libraries have different names). Update: I now try to statically link libssl.a for all of the binaries in the archive. You can also run the included build.unix script to try to automatically build the binaries if your OS is not in the above list or the included binary does not run properly on your system. Let me know how that goes. --- ## IMPORTANT there may be restrictions for you to download, use, or redistribute the above because of cryptographic software they contain or for other reasons.

It also helps to have a solid background color, e.g. -solid). News: Sun Ray Remote Control Toolkit: See the nice set of tools in the Sun Ray Remote Control Toolkit that launch x11vnc automatically for you for certain usage modes. You have to know the name of the machine your SunRay session X server is running on (so you can ssh into it and start x11vnc). You also need to know the X11 DISPLAY number for the session: on a SunRay it could be a large number, e.g. :137, since there are many people with X sessions (Xsun processes) on the same machine. If you don't know it, you can get it by running who(1) in a shell on the SunRay server and looking for the dtlocal entry with your username (and if you don't even know which server machine has your session, you could login to all possible ones looking at the who output for your username...). I put some code in my ~/.dtprofile script that stores $DISPLAY (including the hostname) in a ~/.sunray_current file at session startup (and deletes it when the X session ends) to make it easy to get at the hostname and X11 display number info for my current X sessions when I ssh in and am about to start x11vnc. SunRay Gotcha #1: Note that even though your SunRay X11 DISPLAY is something like :137, x11vnc still tries for port 5900 as its listening port if it can get it, in which case the VNC display (i.e. the information you supply to the VNC viewer) is something like sunray-server:0 (note the :0 corresponding to port 5900, it is not :137). If it cannot get 5900, it tries for 5901, and so on. You can also try to force the port (and thereby the VNC display) using the -rfbport NNNN option. Especially on a busy Sun Ray server it is often difficult to find free ports for both VNC and the HTTP Java applet server to listen on. This script, vnc_findports may be of use for doing this automatically. It suggests x11vnc command line options based on netstat output that lists the occupied ports. It is even more difficult to start vncserver/Xvnc on a busy Sun Ray because then 3 ports (HTTP, VNC, and X11), all separated by 100 are needed! This script, findvncports may be helpful as well. Both scripts start at VNC display :10 and work their way up. SunRay Gotcha #2: If you get an error like: ``` shmget(tile) failed. shmget: No space left on device ``` when starting up x11vnc that most likely means all the shared memory (shm) slots are filled up on your machine. The Solaris default is only 100, and that can get filled up in a week or so on a SunRay server with lots of users. If the shm slot is orphaned (e.g. creator process dies) the slot is not reclaimed. You can view the shm slots with the "ipcs -mA" command. If there are about 100 then you've probably hit this problem. They can be cleaned out (by the owner or by root) using the ipcrm command. I wrote a script shm_clear that finds the orphans and lists or removes them. Longer term, have your SunRay sysadmin add something like this to /etc/system: ``` set shmsys:shminfo_shmmax = 0x2000000 set shmsys:shminfo_shmmni = 0x1000 ``` SunRay Gotcha #3: Some SunRay installations have implemented suspending certain applications when a SunRay session is in a disconnected state (e.g. Java Badge pulled out, utdetach, etc). This is a good thing because it limits hoggy or runaway apps from wasting the shared CPU resource. Think how much CPU and memory I/O is wasted by a bunch of Firefox windows running worthless Flash animations while your session is disconnected! So some sites have implemented scripts to suspend (e.g. kill -STOP) certain apps when your badge is removed from the SunRay terminal. When you reattach, it kill -CONT them. This causes problems for viewing the detached SunRay session via x11vnc: those suspended apps will not respond (their windows will be blank or otherwise inactive). What to do? Well, since you are going to be using the application you might as well unfreeze it rather than starting up a 2nd instance. Here is one way to do it using the kill -CONT mechanism: kill -CONT `ps -ealf | grep ' T ' | grep $LOGNAME | awk '{print $4}'` If you want to be a good citizen and re-freeze them before you exit x11vnc this script could be of use: ``` #!/bin/sh # # kill -STOP/-CONT script for x11vnc (or other) SunRay usage ("freezes" # certain apps from hogging resources when disconnected). # # Put here a pattern that matches the apps that are frozen: # appmatch="java_vm|jre|netscape-bin|firefox-bin|realplay|acroread|mozilla-bin" if [ "X$1" = "Xfreeze" ]; then pkill -STOP -U $LOGNAME "$appmatch" elif [ "X$1" = "Xthaw" ]; then pkill -CONT -U $LOGNAME "$appmatch" elif [ "$RFB_MODE" = "afteraccept" -a "$RFB_STATE" = "NORMAL" ]; then # a valid x11vnc login. if [ "$RFB_CLIENT_COUNT" = "1" ]; then # only one client present. pkill -CONT -U $LOGNAME "$appmatch" fi elif [ "$RFB_MODE" = "gone" -a "$RFB_STATE" = "NORMAL" ]; then # a valid x11vnc login. if [ "$RFB_CLIENT_COUNT" = "0" ]; then # last client present has just left. pkill -STOP -U $LOGNAME "$appmatch" fi fi exit 0 ``` If you called the script "goodcitizen" you could type "goodcitizen thaw" to unfreeze them, and then "goodcitizen freeze" to refreeze them. One could also use these x11vnc options "-afteraccept goodcitizen -gone goodcitizen" to do it automatically. SunRay Gotcha #4: Recent versions of the Sun Ray Server Software SRSS (seems to be version 3.0 or 3.1) have a "misfeature" that when the session is disconnected (i.e. badge/smartcard out) the screen locker (xscreensaver) will freeze the X server just when the "Enter Password" dialog box appears. So you cannot unlock the screen remotely via x11vnc! Update: please see Bob Doolittle's detailed description of the this issue at the bottom of this section. Here "freeze" means "stop other X clients from inserting keyboard and mouse input and from viewing the current contents of the screen". Or something like that; the upshot is x11vnc can't do its normal thing. There are several workarounds for this. 1. The easiest one by far is to put these lines in your $HOME/.dtprofile file: ``` SUN_SUNRAY_UTXLOCK_PREF="/usr/openwin/bin/xlock -mode blank" export SUN_SUNRAY_UTXLOCK_PREF ``` One might argue that xlock isn't particularly "pretty". (Just IMHO, but if something like this not being pretty actually gets in the way of your work I think some introspection may be in order. :-) 2. The problem has been traced to the pam_sunray.so PAM module. Evidently xscreensaver invokes this pam module and it communicates with utsessiond who in turn instructs the Xsun server to not process any synthetic mouse/keyboard input or to update the screen framebuffer. It is not clear if this is by design (security?) or something else. In any event, the problem can be avoided, somewhat drastically, by commenting out the corresponding line in /etc/pam.conf: ``` #xscreensaver auth sufficient /opt/SUNWut/lib/pam_sunray.so syncondisplay ``` Leave the other xscreensaver pam authentication lines unchanged. The dtsession-SunRay line may also need to be commented out to avoid the problem for CDE sessions. N.B. it is possible the application of a SSRS patch, etc, may re-enable that /etc/pam.conf line. It may be difficult to convince a sysadmin to make this change. 3. A more forceful way is to kill the xscreensaver process from a shell prompt whenever you connect via x11vnc and the screen is in a locked state: ``` pkill -U $LOGNAME '^xscreensaver$' ``` And then after you are in be sure to restart it by typing something like: ``` xscreensaver & ``` You may want to avoid restarting it until you are about to disconnect your VNC viewer (since if it locks the screen while you are working you'll be stuck again). 3') The above idea can be done a bit more cleanly by having x11vnc do it. Suppose we called the following script xss_killer: ``` #!/bin/sh # # xss_killer: kill xscreensaver after a valid x11vnc client logs in. # Restart xscreensaver and lock it when the last client # disconnects. PATH=/usr/openwin/bin:/usr/bin:$PATH export PATH if [ "$RFB_MODE" = "afteraccept" -a "$RFB_STATE" = "NORMAL" ]; then # a valid x11vnc login. if [ "$RFB_CLIENT_COUNT" = "1" ]; then # only one client present. pkill -U $LOGNAME '^xscreensaver$' pkill -KILL -U $LOGNAME -f xscreensaver/hacks fi elif [ "$RFB_MODE" = "gone" -a "$RFB_STATE" = "NORMAL" ]; then # a valid x11vnc login. if [ "$RFB_CLIENT_COUNT" = "0" ]; then # last client present has just left. xscreensaver -nosplash & sleep 1 xscreensaver-command -lock & fi fi ``` Then we would run x11vnc with these options: "-afteraccept xss_killer -gone xss_killer". The -afteraccept option (introduced in version 0.8) is used to run a command after a vncviewer has successfully logged in (note that this is a VNC login, not a Unix login, so you may not want to do this if you are really paranoid...) Note if you use the above script and also plan to Ctrl-C (SIGINT) x11vnc you have to run the xscreensaver in a new process group to avoid killing it as well. One way to do this is via this kludge: ``` perl -e 'setpgrp(0,0); exec "xscreensaver -nosplash &"' ``` in the above script. 4. There appears to be a bug in pam_sunray.so in that it doesn't seem to honor the convention that, say, DISPLAY=unix:3 means to use Unix sockets to connect to display 3 on the local machine (this is a bit faster than TCP sockets). Rather, it thinks the display is a non-local one to a machine named "unix" (that usually does not resolve to an IP address). Amusingly, this can be used to bypass the pam_sunray.so blocking of Xsun that prevents one from unlocking the screen remotely via x11vnc. One could put something like this in $HOME/.dtprofile to kill any existing xscreensavers and then start up a fresh xscreensaver using DISPLAY=unix:N ``` # stop/kill any running xscreensavers (probably not running yet, but to be sure) xscreensaver-command -exit pkill -U $LOGNAME '^xscreensaver$' env DISPLAY=`echo $DISPLAY | sed -e 's/^.*:/unix:/'` xscreensaver & ``` Important: Note that all of the above workarounds side-step the pam_sunray.so PAM module in one way or another. You'll need to see if that is appropriate for your site's SunRay / smartcard usage. Also, these hacks may break other things and so you may want to test various scenarios carefully. E.g. check corner cases like XDMCP/dtremote, NSCM, etc. Update May 2008: Here is a useful description of this issue from Bob Doolittle who is a developer for Sun Ray at Sun. I don't have the time to digest and distill it and then adjust the above methods to provide a clearer description, so I just include below the description he sent me with the hope that it will help some users: > In SRSS 4.0 and earlier, the purpose of pam_sunray.so in the "auth" > PAM stack of screensavers is to enable NSCM (and, although this is > much less commonly used, "SC", which is configured when 3rd-party > software is installed to allow smartcards to be used as part of the > authentication process) to work. It should have no effect with > smartcards. Currently, however, it does block the PAM stack for all > sessions, which causes xscreensaver, when it locks a disconnected > session, to not process any mouse or keyboard events as you > describe (unless xscreensaver does an X server grab, however, other > applications should still be able to draw in the session although > xscreensaver may be playing tricks like putting a black window on > top of everything). In both of the NSCM and SC models, > authentication occurs in a separate session before SRSS will > reconnect to the user session, in which case pam_sunray.so causes > xscreensaver to just unlock the screen without prompting the user > to enter their password again. To do this, pam_sunray.so has to > block until the session becomes reconnected, so it can query SRSS > at that time to determine whether the user has already > authenticated or not. In SRSS 4.0 and earlier releases, > pam_sunray.so could have been optimized to not block smartcard > sessions, although since the session is disconnected this typically > isn't important (except in the x11vnc case, as you've observed). > > In SRSS 4.1, however, for increased security the out-of-session > authentication model has been extended to *all* session types, so > pam_sunray.so will be required in all cases unless users are > willing to authenticate twice upon hotdesking (e.g. when their card > is inserted). In future, we may do away with pam_sunray.so, and in > fact with any traditional screen locker in the user session, since > SRSS itself will be providing better security than a screen locker > running entirely within the user's X session is capable of > providing. > > Your trick of setting DISPLAY to unix:DPY will effectively disable > pam_sunray.so (I'm not sure I'd call that a bug - you're going out > of your way to do something that wouldn't occur in the normal > course of events, and really provides no useful value other than to > tickle this behavior in pam_sunray.so). This will mean that, in > SRSS 4.0 and earlier releases, users will be prompted for their > passwords twice when reconnecting to their sessions for NSCM and SC > session types. In 4.1, disabling pam_sunray.so in this way will > cause this double-authentication to occur for *all* sessions, > including simple smartcard sessions. Users may be willing to pay > that price in order to be able to use x11vnc in disconnected > sessions. I like this hack, personally. It's a little less > convenient than some of the other approaches you describe, but it's > lighter-weight and more secure than most of the other approaches, > and provides the value of being able to use x11vnc in locked > sessions. > > Here are some other minor notes: - I wouldn't recommend storing > your display in your .dtprofile, unless you're willing to live with > a single session at a time. Personally, I often find myself using > several sessions, in several FoGs, for short periods of time so > this would certainly break. IMO it's pretty easy to use $DISPLAY to > do what you want on the fly, as needed, so I don't think the price > of breaking multiple-session functionality would be worth the > convenience, to me at least. Here's some ksh/bash syntax to extract > the hostname and display number on the fly which you may find > useful: > > ``` > HOSTNAME=${DISPLAY%:*} > FULLDPY=${DISPLAY#*:} > DPYNUM=${FULLDPY%.*} > ``` > > A final note may give you some insight into other clever hacks in > this area: - Check out utaction. It's a very handy little utility > that can be run as a daemon in the user session which will invoke a > specified command upon session connects and/or disconnects. > Personally, I start one up in my .dtprofile as follows: > > ``` > utaction -c $HOME/.srconnectrc -d $HOME/.srdisconnectrc & > ``` > > This then allows me to construct a .srconnectrc script containing > useful commands I'd like to have run every time I insert my > smartcard, and a .srdisconnectrc script of commands to be run every > time I remove my smartcard (or, connect/disconnect to my session > via NSCM or SC). This can be used for things like notifying a chat > client of away status, as well as some of the hacks you've > described on your page such as freeze/unfreeze, or perhaps to > terminate an xscreensaver and start up a new one with the unix:DPY > $DISPLAY specification as you describe (although it probably makes > most sense to do this at login time, as opposed to every connect or > disconnect event). x11vnc-0.9.17/m4/000077500000000000000000000000001500463450600132535ustar00rootroot00000000000000x11vnc-0.9.17/m4/.gitignore000066400000000000000000000000001500463450600152310ustar00rootroot00000000000000x11vnc-0.9.17/m4/ax_type_socklen_t.m4000066400000000000000000000045711500463450600172360ustar00rootroot00000000000000# =========================================================================== # http://www.gnu.org/software/autoconf-archive/ax_type_socklen_t.html # =========================================================================== # # SYNOPSIS # # AX_TYPE_SOCKLEN_T # # DESCRIPTION # # Check whether sys/socket.h defines type socklen_t.

Some are on the rough side and will need some customization for your use. Many of them are described on the webpage: http://www.karlrunge.com/x11vnc (use your browser's Find action to find them!). Some of them also have documentation near the top of the file. x11vnc -accept scripts: blockdpy.c try to lock screen if local person knocks monitor out of DPMS dtVncPopup CDE/dtksh by Stefan Radman to accept connections, lock screen x11vnc launch wrappers: rx11vnc simple ssh/rsh x11vnc launcher. -S option needs work... rx11vnc.pl perl script tries to do rx11vnc -S tunnelling better. x11vnc -pipeinput/-rawfb utilities: vcinject.pl perl script like LinuxVNC.c, for x11vnc viewing of linux console slide.pl amusing example using x11vnc -rawfb for jpeg slideshow. ranfb.pl example -rawfb setup:./ranfb.pl to set up a framebuffer. uinput.pl test perl script for Linux uinput injection. qt_tslib_inject.pl touchscreen -pipeinput helper for tslib on qtmoko. Misc. scripts: shm_clear list or remove orphaned shm slots from hard x11vnc crashes. x11vnc_loop kludge to run in bg attaching x11vnc to X login. Better to use Xsetup mechanism. Xdummy An LD_PRELOAD kludge to run the Xorg "dummy" device driver like Xvfb. ultravnc_repeater.pl: Unix script to act as UltraVNC repeater proxy. connect_switch: Share HTTPS, VNC, SSH, etc. through a single port (e.g. 443) panner.pl Allows a small rectangle to pan around a desktop more or less. desktop.cgi CGI script for creating multi-user virtual desktops on a server. Also can do port-redirection to internal machines. inet6to4 ipv6 to ipv4 relay (i.e. until libvncserver supports ipv6) deskshot A screenshot utility for configurations that lack other screen capture techniques built into x11vnc.

In other words, it tries to make Xorg/XFree86 with the "dummy" device driver act more like Xvfb(1). The primary motivation for the Xdummy script is to provide a virtual X server for x11vnc but with more features than Xvfb (or Xvnc); however it could be used for other reasons (e.g. better automated testing than with Xvfb.) One nice thing is the dummy server supports RANDR dynamic resizing while Xvfb does not. So, for example, x11vnc+Xdummy terminal services are a little better than x11vnc+Xvfb. To achieve this, while running the real Xserver $program intercepts system and library calls via the LD_PRELOAD method and modifies the behavior to make it work correctly (e.g. avoid the VT stuff.) LD_PRELOAD tricks are usually "clever hacks" and so might not work in all situations or break when something changes. WARNING: Take care in using Xdummy, although it never has it is possible that it could damage hardware. One can use the -prconf option to have it print out the xorg.conf config that it would use and then inspect it carefully before actually using it. This program no longer needs to be run as root as of 12/2009. However, if there are problems for certain situations (usually older servers) it may perform better if run as root (use the -root option.) When running as root remember the previous paragraph and that Xdummy comes without any warranty. gcc/cc and other build tools are required for this script to be able to compile the LD_PRELOAD shared object. Be sure they are installed on the system. See -install and -uninstall described below. Your Linux distribution may not install the dummy driver by default, e.g: /usr/lib/xorg/modules/drivers/dummy_drv.so some have it in a package named xserver-xorg-video-dummy you that need to install. Usage: $program <${program}-args> (actually, the arguments can be supplied in any order.) Examples: $program -install $program :1 $program -debug :1 $program -tmpdir ~/mytmp :1 -nolisten tcp startx example: startx -e bash -- $program :2 -depth 16 (if startx needs to be run as root, you can su(1) to a normal user in the bash shell and then launch ~/.xinitrc or ~/.xsession, gnome-session, startkde, startxfce4, etc.) xdm example: xdm -config /usr/local/dummy/xdm-config -nodaemon where the xdm-config file has line: DisplayManager.servers: /usr/local/dummy/Xservers and /usr/local/dummy/Xservers has lines: :1 local /usr/local/dummy/Xdummy :1 -debug :2 local /usr/local/dummy/Xdummy :2 -debug (-debug is optional) gdm/kdm example: TBD. Root permission and x11vnc: Update: as of 12/2009 this program no longer must be run as root. So try it as non-root before running it as root and/or the following schemes. In some circumstances X server program may need to be run as root. If so, one could run x11vnc as root with -unixpw (it switches to the user that logs in) and that may be OK, some other ideas: - add this to sudo via visudo: ALL ALL = NOPASSWD: /usr/local/bin/Xdummy - use this little suid wrapper: /* * xdummy.c * cc -o ./xdummy xdummy.c sudo cp ./xdummy /usr/local/bin/xdummy sudo chown root:root /usr/local/bin/xdummy sudo chmod u+s /usr/local/bin/xdummy * */ #include #include #include #include int main (int argc, char *argv[]) { extern char **environ; char str[100]; sprintf(str, "XDUMMY_UID=%d", (int) getuid()); putenv(str); setuid(0); setgid(0); execv("/usr/local/bin/Xdummy", argv); exit(1); return 1; } Options: ${program}-args: -install Compile the LD_PRELOAD shared object and install it next to the $program script file as: $0.so When that file exists it is used as the LD_PRELOAD shared object without recompiling. Otherwise, each time $program is run the LD_PRELOAD shared object is compiled as a file in /tmp (or -tmpdir) If you set the environment variable INTERPOSE_GETUID=1 when building, then when $program is run as an ordinary user, the shared object will interpose getuid() calls and pretend to be root. Otherwise it doesn't pretend to be root. You can also set the CFLAGS environment variable to anything else you want on the compile cmdline. -uninstall Remove the file: $0.so The LD_PRELOAD shared object will then be compiled each time this program is run. The X server is not started under -install, -uninstall, or -prconf. :N The DISPLAY (e.g. :15) is often the first argument. It is passed to the real X server and also used by the Xdummy script as an identifier. -geom geom1[,geom2...] Take the geometry (e.g. 1024x768) or list of geometries and insert them into the Screen section of the tweaked X server config file. Use this to have a different geometry than the one(s) in the system config file. The option -geometry can be used instead of -geom; x11vnc calls Xdummy and Xvfb this way. -nomodelines When you specify -geom/-geometry, $program will create Modelines for each geometry and put them in the Monitor section. If you do not want this then supply -nomodelines. -depth n Use pixel color depth n (e.g. 8, 16, or 24). This makes sure the X config file has a Screen.Display subsection of this depth. Note this option is ALSO passed to the X server. -DEPTH n Same as -depth, except not passed to X server. -tmpdir dir Specify a temporary directory, owned by you and only writable by you. This is used in place of /tmp/Xdummy.\$USER/.. to place the $program.so shared object, tweaked config files, etc. -nonroot Run in non-root mode (working 12/2009, now default) -root Run as root (may still be needed in some environments.) Same as XDUMMY_RUN_AS_ROOT=1. -nosudo Do not try to use sudo(1) when re-running as root, use su(1) instead. -xserver path Specify the path to the Xserver to use. Default is to try "Xorg" first and then "XFree86". If those are not in \$PATH, it tries these locations: /usr/bin/Xorg /usr/X11R6/bin/Xorg /usr/X11R6/bin/XFree86 -n Do not run the command to start the X server, just show the command that $program would run. The LD_PRELOAD shared object will be built, if needed. Also note any XDUMMY* environment variables that need to be set. -prconf Print, to stdout, the tweaked Xorg/XFree86 config file (-config and -xf86config server options, respectively.) The Xserver is not started. -notweak Do not tweak (modify) the Xorg/XFree86 config file (system or server command line) at all. The -geom and similar config file modifications are ignored. It is up to you to make sure it is a working config file (e.g. "dummy" driver, etc.) Perhaps you want to use a file based on the -prconf output. -debug Extra debugging output. -strace strace(1) the Xserver process (for troubleshooting.) -ltrace ltrace(1) instead of strace (can be slow.) -h, -help Print out this help. Xserver-args: Most of the Xorg and XFree86 options will work and are simply passed along if you supply them. Important ones that may be supplied if missing: :N X Display number for server to use. vtNN Linux virtual terminal (VT) to use (a VT is currently still used, just not switched to and from.) -config file Driver "dummy" tweaked config file, a -xf86config file number of settings are tweaked besides Driver. If -config/-xf86config is not given, the system one (e.g. /etc/X11/xorg.conf) is used. If the system one cannot be found, a built-in one is used. Any settings in the config file that are not consistent with "dummy" mode will be overwritten (unless -notweak is specified.) Use -config xdummy-builtin to force usage of the builtin config. If "file" is only a basename (e.g. "xorg.dummy.conf") with no /'s, then no tweaking of it is done: the X server will look for that basename via its normal search algorithm. If the found file does not refer to the "dummy" driver, etc, then the X server will fail. Notes: The Xorg/XFree86 "dummy" driver is currently undocumented. It works well in this mode, but it is evidently not intended for end-users. So it could be removed or broken at any time. If the display Xserver-arg (e.g. :1) is not given, or ":" is given that indicates $program should try to find a free one (based on tcp ports.) If the display virtual terminal, VT, (e.g. vt9) is not given that indicates $program should try to find a free one (or guess a high one.) This program is not completely secure WRT files in /tmp (but it tries to a good degree.) Better is to use the -tmpdir option to supply a directory only writable by you. Even better is to get rid of users on the local machine you do not trust :-) Set XDUMMY_SET_XV=1 to turn on debugging output for this script.

It is a kludge to try to * "block" access via the physical display while x11vnc is running. * * The expected application is that of a user who screen-locks his * workstation before leaving and then later unlocks it remotely via * x11vnc. The user is concerned people with physical access to the * machine will be watching, etc. * * Of course if people have physical access to the machine there are * much larger potential security problems, but the idea here is to put * up a larger barrier than simply turning on the monitor and tapping * the mouse (i.e. to wake up the monitor from DPMS and then observe * the x11vnc activity). * * This program requires DPMS support in the video card and monitor, * and the DPMS extension in the X server and the corresponding * library with the DPMS API (libXext). * * It starts off by forcing the state to be DPMSModeOff (lowest power). * Then it periodically (a few times a second) checks if the system is * still in that state. If it discovers it to be in another state, it * immediately runs, as a separate command, a screen-lock program, "xlock" * by default. The environment variable XLOCK_CMD or -lock option can * override this default. "xscreensaver-command" might be another choice. * * It is up to the user to make sure the screen-lock command works * and PATH is set up correctly, etc. The command can do anything, * it doesn't have to lock the screen. It could make the sound of a * dog barking, for example :-) * * The option '-grab' causes the program to additionally call * XGrabServer() to try to prevent physical mouse or keyboard input to get * to any applications on the screen. NOTE: do NOT use, not working yet! * Freezes everything. * * The options: -display and -auth can be used to set the DISPLAY and * XAUTHORITY environment variables via the command line. * * The options -standby and -suspend change the desired DPMS level * to be DPMSModeStandby and DPMSModeSuspend, respectively. * * The option '-f flagfile' indicates a flag file to watch for to cause * the program to clean up and exit once it exists. No screen locking is * done when the file appears: it is an 'all clear' flag. Presumably the * x11vnc user has relocked the screen before the flagfile is created. * See below for coupling this behavior with the -gone command. * * The option '-bg' causes the program to fork into the background and * return 0 if everything looks ok. If there was an error up to that * point the return value would be 1. * * Option '-v' prints more info out, useful for testing and debugging. * * * These options allow this sort of x11vnc usage: * * x11vnc ... -accept "blockdpy -bg -f $HOME/.bdpy" -gone "touch $HOME/.bdpy" * * (this may also work for gone: -gone "killall blockdpy") * * In the above, once a client connects this program starts up in the * background and monitors the DPMS level. When the client disconnects * (he relocked the screen before doing so) the flag file is created and * so this program exits normally. On the other hand, if the physical * mouse or keyboard was used during the session, this program would * have locked the screen as soon as it noticed the DPMS change. * * One could create shell scripts for -accept and -gone that do much * more sophisticated things. This would be needed if more than one * client connects at a time. * * It is important to remember once this program locks the screen * it *exits*, so nothing will be watching the screen at that point. * Don't immediately unlock the screen from in x11vnc!! Best to think * about what might have happened, disconnect the VNC viewer, and then * restart x11vnc (thereby having this monitoring program started again). * * * To compile on Linux or Solaris: cc -o blockdpy blockdpy.c -L /usr/X11R6/lib -L /usr/openwin/lib -lX11 -lXext * (may also need -I /usr/.../include on older machines). * */ #include #include #include #include #include #include #include #include #include Display *dpy = NULL; CARD16 standby, suspend, off; int grab = 0; int verbose = 0; int bg = 0; /* for sleeping some number of millisecs */ struct timeval _mysleep; #define msleep(x) \ _mysleep.tv_sec = ((x)*1000) / 1000000; \ _mysleep.tv_usec = ((x)*1000) % 1000000; \ select(0, NULL, NULL, NULL, &_mysleep); /* called on signal or if DPMS changed, or other problem */ void reset(int sig) { if (grab) { if (verbose) { fprintf(stderr, "calling XUngrabServer()\n"); } XUngrabServer(dpy); } if (verbose) { fprintf(stderr, "resetting original DPMS values.\n"); } fprintf(stderr, "blockdpy: reset sig=%d called\n", sig); DPMSEnable(dpy); DPMSSetTimeouts(dpy, standby, suspend, off); XFlush(dpy); if (sig) { XCloseDisplay(dpy); exit(0); } } int main(int argc, char** argv) { int verbose = 0, bg = 0; int i, ev, er; char *lock_cmd = "xlock"; char *flag_file = NULL; char estr[100], cmd[500]; struct stat sbuf; CARD16 power; CARD16 desired = DPMSModeOff; BOOL state; /* setup the lock command. it may be reset by -lock below. */ if (getenv("XLOCK_CMD")) { lock_cmd = (char *) getenv("XLOCK_CMD"); } /* process cmd line: */ for (i=1; i # # connect_switch is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2 of the License, or (at # your option) any later version. # # connect_switch is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The user desktop sessions run in 'Xvfb' displays # that are created automatically. # # This script should/must be served by an HTTPS (i.e. SSL) webserver, # otherwise the unix and vnc passwords would be sent over the network # unencrypted (see below to disable if you really want to.) # # The Java VNC Viewer applet connections are encrypted by SSL as well. # # You can use this script to provide unix users desktops available on # demand via any Java enabled web browser. One could also use this for # a special-purpose 'single application' service running in a minimal # window manager. # # One example of a special-purpose application would be a scientific # data visualization tool running on a server where the data is housed. # To do this set $x11vnc_extra_opts = '-env FD_PROG=/path/to/app/launcher' # where the program launches your special purpose application. A very # simple example: '-env FD_PROG=/usr/bin/xclock' # # # Depending on where you place this script, the user accesses the service # with the URL: # # https://your.webserver.net/cgi-bin/desktop.cgi # # Then they login with their unix username and password to get their # own desktop session. # # If the user has an existing desktop it is connected to directly, # otherwise a new session is created inside an Xvfb display and then # connected to by VNC. # # It is possible to do port redirection to other machines running SSL # enabled VNC servers (see below.) This script does not start the VNC # servers on the other machines, although with some extra rigging you # should be able to do that as well. # # You can customize the login procedure to whatever you want by modifying # this script, or by using ideas in this script write your own PHP, # (for example), script. # ########################################################################## # Overriding default settings: # # If you want to override any settings in this script and do not # want to edit this script create the assignments in a file named # 'desktop.cgi.conf' in the same directory as desktop.cgi. It will be # sourced after the defaults are set. The format of desktop.cgi.conf # is simply perl statements that make the assignments. # # For example, if you put something like this in desktop.cgi.conf: # # $x11vnc = '/usr/local/bin/x11vnc'; # # that will set the path to the x11vnc binary to that location. Look at # the settings below for the other variables that you can modify, for # example one could set $allowed_users_file. # ########################################################################## # x11vnc: # # You need to install x11vnc or otherwise have it available. It is # REQUIRED that you use x11vnc 0.9.10 or later. It won't work with # earlier versions. See below the $x11vnc parameter that you can set # to the full path to x11vnc. # ########################################################################## # Xvfb: # # Note that the x11vnc -create virtual desktop service used below requires # that you install the 'Xvfb' program. On debian this is currently done # via 'apt-get install xvfb'. # # If you are having trouble getting 'x11vnc -create' to work with this # script (it can be tricky), try it manually and/or see the x11vnc FAQ # links below. # ########################################################################## # Apache httpd: # # You should put this script in, say, a cgi-bin directory. Enable cgi # scripts in your apache (or other httpd) config. For example, we have # these lines (not commented): # # In httpd.conf: # # ScriptAlias /cgi-bin/ "/dist/apache/2.0/cgi-bin/" # # # AllowOverride None # Options None # Order allow,deny # Allow from all # # # and in ssl.conf: # # # SSLOptions +StdEnvVars # # # Do not be confused by the non-standard /dist/apache/2.0 apache # installation location that we happen to use. Yours will be different. # # You can test that you have CGI scripts working properly with the # 'test-cgi' and 'printenv' scripts apache provides. # # Copy this file (desktop.cgi) to /dist/apache/2.0/cgi-bin and then run # 'chmod 755 ...' on it to make it executable. # ########################################################################## # Applet Jar files served by apache: # # You will *also* need to copy the x11vnc classes/ssl/UltraViewerSSL.jar # file to the httpd DocumentRoot to be accessible by: /UltraViewerSSL.jar # in a URL (or change $applet_jar below or the html in $applet_html if # you want to use a different location.) # # This location is relative to the apache DocumentRoot 'htdocs' directory. # For our (non-standard location installation) that meant we copied the # file to: # # /dist/apache/2.0/htdocs/UltraViewerSSL.jar # # (your DocumentRoot directory will be different.) # # The VncViewer.jar (tightvnc) will also work, but you need to change # the $applet_jar below. You can get these jar files from the x11vnc # tarball from: # # http://www.karlrunge.com/x11vnc/#downloading # # This script requires x11vnc 0.9.10 or later. # # Note that the usage mode for this script is a different from regular # 'x11vnc -http ...' usage where x11vnc acts as a mini web server and # serves its own applet jars. We don't use that mode for this script. # Apache (httpd) serves the jars. # # ########################################################################## # Notes and Information: # # Each x11vnc server created for a user login will listen on its own port # (see below for port selection schemes.) Your firewall must let in *ALL* # of these ports (e.g. a port range, see below for the syntax.) # # It is also possible, although not as reliable, to do all of this through # a single port, see the fixed port scheme $find_free_port = 'fixed:5910' # below. This single port mode must be different from apache's port # (usually 443 for https) and must also be allowed in by your firewall. # # Note: The fixed port scheme is DISABLED by default. # # It is also possible to have this script act as a vnc redirector to SSL # enabled VNC servers running on *other* machines inside your firewall # (presumably the users' desktops) See the $enable_port_redirection # setting below. The user provides 'username@host:port' instead of just # 'username' when she logs in. This script doesn't start VNC servers # on those other machines, the servers must be running there already. # (If you want this script to start them you will need to add it # yourself.) It is possible to provide a host:port allow list to limit # which internal machines and ports can be redirected to. This is the # $port_redirection_allowed_hosts parameter. # # Note: The vnc redirector scheme is DISABLED by default. # # Note there are *two* SSL certificates involved that the user may be # asked to inspect: apache's SSL cert and x11vnc's SSL cert. This may # confuse naive users. You may want to use the same cert for both. # # This script provides one example on how to provide the service. You can # customize it to meet your needs, e.g. switch to php, newer cgi modules, # different authentication, SQL database for user authentication, etc, # etc. If you plan to use it in production, please examine all security # aspects of it carefully; read the comments in the script for more info. # # More information and background and troubleshooting: # # http://www.karlrunge.com/x11vnc/faq.html#faq-xvfb # http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-tunnel-viewers # http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-java-viewer-proxy # http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-portal # http://www.karlrunge.com/x11vnc/faq.html#faq-unix-passwords # http://www.karlrunge.com/x11vnc/faq.html#faq-userlogin # # # Please also read the comments below for changing specific settings. # You can modify them in this script or by override file 'desktop.cgi.conf' #------------------------------------------------------------------------- # Copyright (c) 2010 by Karl J.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. x11vnc-0.9.17/misc/enhanced_tightvnc_viewer/README000066400000000000000000000640621500463450600216120ustar00rootroot00000000000000 Enhanced TightVNC Viewer (SSVNC: SSL/SSH VNC viewer) Copyright (c) 2006-2009 Karl J. Runge All rights reserved. These bundles provide 1) An enhanced TightVNC Viewer on Unix, 2) Binaries for many Operating Systems (including Windows and Mac OS X) for your convenience, 3) Wrapper scripts and a GUI for gluing them all together. One can straight-forwardly download all of the components and get them to work together by oneself: this bundle is mostly for your convenience to combine and wrap together the freely available software. Bundled software co-shipped is copyright and licensed by others.

All the files and information in this project are provided "AS IS" without any warranty of any kind. Use them at your own risk. ============================================================================= This bundle contains a convenient collection of enhanced TightVNC viewers and stunnel binaries for different flavors of Unix and wrapper scripts and a GUI front-end to glue them together. Automatic SSL and SSH encryption tunnelling is provided. A Windows SSL wrapper for the bundled TightVNC binary and other utilities are provided. (Launch ssvnc.exe in the Windows subdirectory). The short name of the project is "ssvnc" for SSL/SSH VNC Viewer. It is a self-contained bundle, you could carry it around on, say, a USB memory stick for secure VNC viewing from almost any machine, Unix, Mac, or Windows. Features: -------- The enhanced TightVNC viewer features are: - SSL support for connections using the bundled stunnel program. - Automatic SSH connections from the GUI (ssh must already be installed on Unix; bundled plink is used on Windows) - Ability to Save and Load VNC profiles for different hosts. - You can also use your own VNC Viewer, e.g. UltraVNC or RealVNC, with the front-end GUI or scripts if you like. - Create or Import SSL Certificates and Private Keys. - Reverse (viewer listening) VNC connections via SSL and SSH. - VeNCrypt SSL/TLS VNC encryption support (used by VeNCrypt, QEMU, ggi, libvirt/virt-manager/xen, vinagre/gvncviewer/gtk-vnc) - ANONTLS SSL/TLS VNC encryption support (used by Vino) - VeNCrypt and ANONTLS are also enabled for any 3rd party VNC Viewer (e.g. RealVNC, TightVNC, UltraVNC ...) on Unix, MacOSX, and Windows via the provided SSVNC VeNCrypt Viewer Bridge tool (use 'Change VNC Viewer' to select the one you want.) - Support for Web Proxies, SOCKS Proxies, and the UltraVNC repeater proxy (e.g. repeater://host:port+ID:1234). Multiple proxies may be chained together (3 max). - Support for SSH Gateway connections and non-standard SSH ports. - Automatic Service tunnelling via SSH for CUPS and SMB Printing, ESD/ARTSD Audio, and SMB (Windows/Samba) filesystem mounting. - Sets up any additional SSH port redirections that you want. - Zeroconf (aka Bonjour) is used on Unix and Mac OS X to find VNC servers on your local network if the avahi-browse or dns-sd program is available and in your PATH. - Port Knocking for "closed port" SSH/SSL connections. In addition to a simple fixed port sequence and one-time-pad implementation, a hook is also provided to run any port knocking client before a connecting. - Support for native MacOS X usage with bundled Chicken of the VNC viewer (the Unix X11 viewer is also provided for MacOS X, and is better IMHO). - Dynamic VNC Server Port determination and redirection (using ssh's builtin SOCKS proxy, -D) for servers like x11vnc that print out PORT= at startup. - Unix Username and Password entry for use with "x11vnc -unixpw" type login dialogs. - Simplified mode launched by command "sshvnc" that is SSH Only. - Simplified mode launched by command "tsvnc" that provides a VNC "Terminal Services" mode (uses x11vnc on the remote side). (the following features only apply to the bundled Unix tightvnc viewer including MacOS X) - rfbNewFBSize VNC support (screen resizing) - Client-side Scaling of the Viewer. - ZRLE VNC encoding support (RealVNC's encoding) - Support for the ZYWRLE encoding, a wavelet based extension to ZRLE to improve compression of motion video and photo regions. - TurboVNC support (VirtualGL's modified TightVNC encoding; requires TurboJPEG library) - Pipelined Updates of the framebuffer as in TurboVNC (asks for the next update before the current one has finished downloading; this gives some speedup on high latency connections.) - Cursor alphablending with x11vnc at 32bpp (-alpha option) - Option "-unixpw ..." for use with "x11vnc -unixpw" login dialogs. - Support for UltraVNC extensions: Single Window, Disable Server-side Input, 1/n Server side scaling, Text Chat (shell terminal UI). Both UltraVNC and x11vnc servers support these extensions - UltraVNC File Transfer via an auxiliary Java helper program (java must be in $PATH). Note that the x11vnc server supports UltraVNC file transfer. - Connection support for the UltraVNC repeater proxy (-repeater option). - Support for UltraVNC Single Click operation. (both unencrypted: SC I, and SSL encrypted: SC III) - Support for UltraVNC DSM Encryption Plugin mode. (ARC4 and AESV2, MSRC4, and SecureVNC) - Support for UltraVNC MS-Logon authentication (NOTE: the UltraVNC MS-Logon key exchange implementation is very weak; an eavesdropper on the network can recover your Windows password easily in a few seconds; you need to use an additional encrypted tunnel with MS-Logon.) - Support for symmetric encryption (including blowfish and 3des ciphers) to Non-UltraVNC Servers. Any server using the same encryption method will work, e.g.: x11vnc -enc blowfish:./my.key - Instead of hostname:display one can also supply "exec=command args..." to connect the viewer to the stdio of an external command (e.g. stunnel or socat) rather than using a TCP/IP socket. Unix domain sockets, e.g. /path/to/unix/socket, and a previously opened file descriptor fd=0, work too. - Local Port Protections for STUNNEL and SSH: avoid having for long periods of time a listening port on the the local (VNC viewer) side that redirects to the remote side. - Reverse (viewer listening) VNC connections can show a Popup dialog asking whether to accept the connection or not (-acceptpopup.) The extra info provided by UltraVNC Single Click reverse connections is also supported (-acceptpopupsc) - Extremely low color modes: 64 and 8 colors in 8bpp (-use64/-bgr222, -use8/-bgr111) - Medium color mode: 16bpp mode even for 32bpp Viewer display (-16bpp/-bgr565) - x11vnc's client-side caching -ncache method cropping option (-ycrop n). This will "hide" the large pixel buffer cache below the actual display. Set to actual height or use -1 for autodetection (tall screens are autodetected by default). - Escape Keys: enable a set of modifier keys so when they are all pressed down you can invoke Popup menu actions via keystrokes. I.e., a set of 'Hot Keys'. One can also pan (move) the desktop inside the viewport via Arrow keys or a mouse drag. - Scrollbar width setting: -sbwidth n, the default is very thin, 2 pixels, for less distracting -ycrop usage. - Selection text sending and receiving can be fine-tuned with the -sendclipboard, -sendalways, and -recvtext options. - TightVNC compression and quality levels are automatically set based on observed network latency (n.b. not bandwidth.) - Improvements to the Popup menu, all of these can now be changed dynamically via the menu: ViewOnly, Toggle Bell, CursorShape updates, X11 Cursor, Cursor Alphablending, Toggle Tight/ZRLE, Toggle JPEG, FullColor/16bpp/8bpp (256/64/8 colors), Greyscale for low color modes, Scaling the Viewer resolution, Escape Keys, Pipeline Updates, and others, including UltraVNC extensions. - Maintains its own BackingStore if the X server does not - The default for localhost:0 connections is not raw encoding (local machine). Default assumes you are using SSH tunnel. Use -rawlocal to revert. - XGrabServer support for fullscreen mode, for old window managers (-grab/-graball option). - Fix for Popup menu positioning for old window managers (-popupfix option). - Run vncviewer -help for all options. The list of software bundled in the archive files: TightVNC Viewer (windows, unix, macosx) Chicken of the VNC Viewer (macosx) Stunnel (windows, unix, macosx) Putty/Plink/Pageant (windows) OpenSSL (windows) esound (windows) These are all self-contained in the bundle directory: they will not be installed on your system. Just un-zip or un-tar the file you downloaded and run it straight from its directory. Quick Start: ----------- Unix and Mac OS X: Inside a Terminal do something like the following. Unpack the archive: % gzip -dc ssvnc-1.0.28.tar.gz | tar xvf - Run the GUI: % ./ssvnc/Unix/ssvnc (for Unix) % ./ssvnc/MacOSX/ssvnc (for Mac OS X) The smaller file "ssvnc_no_windows-1.0.28.tar.gz" could have been used as well. On MacOSX you could also click on the SSVNC app icon in the Finder. On MacOSX if you don't like the Chicken of the VNC (e.g. no local cursors, no screen size rescaling, and no password prompting), and you have the XDarwin X server installed, you can set DISPLAY before starting ssvnc (or type DISPLAY=... in Host:Disp and hit Return). Then our enhanced TightVNC viewer will be used instead of COTVNC. Update: there is now a 'Use X11 vncviewer on MacOSX' under Options ... If you want a SSH-only tool (without the distractions of SSL) run the command: sshvnc instead of "ssvnc". Or click "SSH-Only Mode" under Options. Control-h will toggle between the two modes. If you want a simple VNC Terminal Services only mode (requires x11vnc on the remote server) run the command: tsvnc instead of "ssvnc". Or click "Terminal Services" under Options. Control-t will toggle between the two modes. "tsvnc profile-name" and "tsvnc user@hostname" work too. Unix/MacOSX Install: There is no standard install for the bundles, but you can make symlinks like so: cd /a/directory/in/PATH ln -s /path/to/ssvnc/bin/{s,t}* . Or put /path/to/ssvnc/bin, /path/to/ssvnc/Unix, or /path/to/ssvnc/MacOSX in your PATH. For the conventional source tarball it will compile and install, e.g.: gzip -dc ssvnc-1.0.28.src.tar.gz | tar xvf - cd ssvnc-1.0.28 make config make all make PREFIX=/my/install/dir install then have /my/install/dir/bin in your PATH. Windows: Unzip, using WinZip or a similar utility, the zip file: ssvnc-1.0.28.zip Run the GUI, e.g.: Start -> Run -> Browse and then navigate to .../ssvnc/Windows/ssvnc.exe select Open, and then OK to launch it. The smaller file "ssvnc_windows_only-1.0.28.zip" could have been used as well. You can make a Windows shortcut to this program if you want to. See the Windows/README.txt for more info. If you want a SSH-only tool (without the distractions of SSL) run the command: sshvnc.bat Or click "SSH-Only Mode" under Options. If you want a simple VNC Terminal Services only mode (requires x11vnc on the remote server) run the command: tsvnc.bat Or click "Terminal Services" under Options. Control-t will toggle between the two modes. "tsvnc profile-name" and "tsvnc user@hostname" work too. Important Note for Windows Vista: One user reports that on Windows Vista if you move or extract the "ssvnc" folder down to the "Program Files" folder you will be prompted to do this as the Administrator. But then when you start up ssvnc, as a regular user, it cannot create files in that folder and so it fails to run properly. We recommend to not copy or extract the "ssvnc" folder into "Program Files". Rather, extract it to somewhere you have write permission (e.g. C:\ or your User dir) and create a Shortcut to ssvnc.exe on the desktop. If you must put a launcher file down in "Program Files", perhaps an "ssvnc.bat" that looks like this: C: cd \ssvnc\Windows ssvnc.exe SSH-ONLY Mode: -------------- If you don't care for SSL and the distractions it provides in the GUI, run "sshvnc" (unix/macosx) or "sshvnc.bat" (windows) to run an SSH only version of the GUI. Terminal Services Mode ---------------------- There is an even simpler mode that uses x11vnc on the remote side for the session finding and management. Run "tsvnc" (unix/macosx) or "tsvnc.bat" (windows) to run the Terminal Services version of the GUI. Bundle Info: ------------ The bundle files unpack a directory/folder named: ssvnc It contains these programs to launch the GUI: Windows/ssvnc.exe for Windows MacOSX/ssvnc for Mac OS X Unix/ssvnc for Unix (the Mac OS X and Unix launchers are simply links to the bin directory). Your bundle file should have included binaries for many OS's: Linux, Solaris, FreeBSD, etc. Unpack your archive and see the subdirectories of ./bin for the ones that were shipped in this project, e.g. ./bin/Linux.i686 Run "uname -sm" to see your OS+arch combination (n.b. all Linux x86 are mapped to Linux.i686). (See the ./bin/ssvnc_cmd -h output for how to override platform autodection via the UNAME env. var). Memory Stick Usage: ------------------- If you create a directory named "Home" in that toplevel ssvnc directory then that will be used as the base for storing VNC profiles and certificates. Also, for convenience, if you first run the command with "." as an argument (e.g. "ssvnc .") it will automatically create that "Home" directory for you. This is handy if you want to place SSVNC on a USB flash drive that you carry around for mobile use and you want the profiles you create to stay with the drive (otherwise you'd have to browse to the drive directory each time you load or save). One user on Windows created a BAT file to launch SSVNC and needed to do this to get the Home directory correct: cd \ssvnc\Windows start \ssvnc\Windows\ssvnc.exe (an optional profile name can be supplied to the ssvnc.exe line) WARNING: if you use ssvnc from an "Internet Cafe", i.e. an untrusted computer, an intruder may be capturing keystrokes etc. External Dependencies: ---------------------- On Windows everything is included. Let us know if you find otherwise. On Unix depending on what you do you need these programs installed: - basic unix utilities (sh, ls, cat, awk, sed, etc..) - tcl/tk (wish interpreter) - xterm - perl - ssh - openssl Lesser used ones: netcat, esd/artsd, smbclient, smbmount, cups On Mac OS X depending on what you do you need these programs installed: - basic unix utilities (sh, ls, cat, awk, sed, etc..) - tcl/tk (wish interpreter) - Terminal - perl - ssh - openssl Lesser used ones: netcat, smbclient, cups Most Mac OS X and Unix OS come with the main components installed. See the README.src for a more detailed description of dependencies. TurboVNC Support: ---------------- TurboVNC is supported in an experimental way. To it build via the build.unix script described in the next section, do something like: env TURBOVNC='-L/DIR -Xlinker --rpath=/DIR -lturbojpeg' ./build.unix where you replace /DIR with the directory where the libturbojpeg.so (http://sourceforge.net/project/showfiles.php?group_id=117509&package_id=166100) is installed. You may not need to set rpath if libturbojpeg.so is installed in a standard location or you use LD_LIBRARY_PATH to point to it. See the turbovnc/README in the vnc_unixsrc/vncviewer directory for more info. You can find it in the ssvnc source tarball and also in: src/zips/vnc_unixsrc_vncviewer.patched.tar More TurboVNC features will be enabled in the future. If you need to Build: -------------------- If your OS/arch is not included or the provided binary has the wrong library dependencies, etc. the script "build.unix" may be able to successfully build on for you and deposit the binaries down in ./bin/... using the included source code. It is a hack but usually works. You MUST run the build.unix script from this directory (that this toplevel README is in, i.e "ssvnc") and like this: ./build.unix To use custom locations for libraries see the LDFLAGS_OS and CPPFLAGS_OS description at the top of the build.unix script. You can set these env. vars to customize the build: SSVNC_BUILD_NO_STATIC=1 do not try to statically link libs SSVNC_BUILD_FORCE_OVERWRITE=1 do not prompt about existing binaries SSVNC_BUILD_SKIP_VIEWER=1 do not build vncviewer SSVNC_BUILD_SKIP_STUNNEL=1 do not build stunnel SSVNC_BUILD_ULTRAFTP=1 only build the file xfer helper jar here is an example to build only the vncviewer and with normal library linking (and in a more or less automated way): env SSVNC_BUILD_NO_STATIC=1 SSVNC_BUILD_FORCE_OVERWRITE=1 SSVNC_BUILD_SKIP_STUNNEL=1 ./build.unix Feel free to ask us if you need help running ./build.unix Convential Build: A more conventional source tarball is provided in ssvnc-x.y.z.src.tar.gz. It uses a more or less familiar 'make config; make all; make PREFIX=path install' method. It does not include stunnel, so that must be installed on the system separately. The programs: ------------ Unpack your archive, and you will see "bin", "Windows", "src" directories and other files. The command line wrapper scripts: ./bin/ssvnc_cmd ./bin/tightvncviewer are the main programs that are run and will try to autodetect your OS+arch combination and if binaries are present for it automatically use them. (if not found try the running the build.unix script). If you prefer a GUI to prompt for parameters and then start ssvnc_cmd you can run this instead: ./bin/ssvnc this is the same GUI that is run on Windows (the ssvnc.exe). There are also: ./bin/sshvnc (SSH-Only) ./bin/tsvnc (Terminal Services Mode) For convenience, you can make symlinks from a directory in your PATH to any of the 3 programs above you wish to run. That is all you usually need to do for it to pick up all of the binaries, utils, etc. E.g. assuming $HOME/bin is in your $PATH: cd $HOME/bin ln -s /path/to/ssvnc/bin/{s,t}* . (note the "." at the end). The above commands is basically the way to "install" this on Unix or MacOS X. Also links to the GUI launcher script are provided in: MacOSX/ssvnc Unix/ssvnc and sshvnc and tsvnc. You could also put the Unix or MacOSX directory in your PATH. On Windows unpack your archive and run: Windows/ssvnc.exe Examples: -------- The following assume you are in the toplevel directory of the archive you unpacked. Use enhanced TightVNC unix viewer to connect to x11vnc via SSL: ./bin/ssvnc_cmd far-away.east:0 ./bin/tightvncviewer -ssl far-away.east:0 (same) ./bin/ssvnc (start GUI launcher) Use enhanced TightVNC unix viewer without SSL: ./bin/tightvncviewer far-away.east:0 Use SSL to connect to a x11vnc server, and also verify the server's identity using the SSL Certificate in the file ./x11vnc.pem: ./bin/ssvnc_cmd -alpha -verify ./x11vnc.pem far-away.east:0 (also turns on the viewer-side cursor alphablending hack). Brief description of the subdirectories: --------------------------------------- ./bin/util some utility scripts, e.g. ss_vncviewer and ssvnc.tcl ./src source code and patches. ./src/zips zip files of source code and binaries. ./src/vnc_unixsrc unpacked tightvnc source code tree. ./src/stunnel-4.14 unpacked stunnel source code tree. ./src/patches patches to TightVNC viewer for the new features on Unix (used by build.unix). ./src/tmp temporary build dir for build.unix (the last four are used by build.unix) ./man man pages for TightVNC viewer and stunnel. ./Windows Stock TightVNC viewer and Stunnel, Openssl etc Windows binaries. ssvnc.exe is the program to run. ./MacOSX contains an unpacked Chicken of the VNC viewer and a symlink to ssvnc. ./Unix contains a symlink to ssvnc. Depending on which bundle you use not all of the above may be present. The smallest bundles with binaries are: ssvnc_windows_only-1.x.y.zip Windows ssvnc_no_windows-1.x.y.tar.gz Unix and MacOSX however, the tiny scripts only one (only 60KB) will run properly on Unix as long as you install external vncviewer and stunnel packages: ssvnc_unix_minimal-1.x.y.tar.gz Untrusted Local Users: --------------------- *IMPORTANT WARNING*: If you run SSVNC on a workstation or computer that other users can log into and you DO NOT TRUST these users (it is a shame but sometimes one has to work in an environment like this), then please note the following warning. By 'do not trust' we mean they might try to gain access to remote machines you connect to via SSVNC. Note that an untrusted local user can often obtain root access in a short amount of time; if a user has achieved that, then all bets are off for ANYTHING that you do on the workstation. It is best to get rid of Untrusted Local Users as soon as possible. Both the SSL and SSH tunnels set up by SSVNC listen on certain ports on the 'localhost' address and redirect TCP connections to the remote machine; usually the VNC server running there (but it could also be another service, e.g. CUPS printing). These are the stunnel(8) SSL redirection and the ssh(1) '-L' port redirection. Because 'localhost' is used only users or programs on the same workstation that is running SSVNC can connect to these ports, however this includes any local users (not just the user running SSVNC.) If the untrusted local user tries to connect to these ports, he may succeed in varying degrees to gain access to the remote machine. We now list some safeguards one can put in place to try to make this more difficult to achieve. It probably pays to have the VNC server require a password, even though there has already been SSL or SSH authentication (via certificates or passwords). In general if the VNC Server requires SSL authentication of the viewer that helps, unless the untrusted local user has gained access to your SSVNC certificate keys. If the VNC server is configured to only allow one viewer connection at a time, then the window of opportunity that the untrusted local user can use is greatly reduced: he might only have a second or two between the tunnel being set up and the SSVNC vncviewer connecting to it (i.e. if the VNC server only allows a single connection, the untrusted local user cannot connect once your session is established). Similarly, when you disconnect the tunnel is torn down quickly and there is little or no window of opportunity to connect (e.g. x11vnc in its default mode exits after the first client disconnects). Also for SSL tunnelling with stunnel(8) on Unix using one of the SSVNC prebuilt 'bundles', a patched stunnel is provided that denies all connections after the first one, and exits when the first one closes. This is not true if the system installed stunnel(8) is used and is not true when using SSVNC on Windows. The following are two experimental features that are added to SSVNC to improve the situation for the SSL/stunnel case. Set them via Options -> Advanced -> "STUNNEL Local Port Protections". 1) For SSL tunnelling with stunnel(8) on Unix there is a setting 'Use stunnel EXEC mode' (experimental) that will try to exec(2) stunnel instead of using a listening socket. This will require using the specially modified vncviewer unix viewer provided by SSVNC. If this mode proves stable it will become the default. 2) For SSL tunnelling with stunnel(8) on Unix there is a setting 'Use stunnel IDENT check' (experimental) to limit socket connections to be from you (this assumes the untrusted local user has not become root on your workstation and has modified your local IDENT check service; if he has you have much bigger problems to worry about...) There is also one simple LD_PRELOAD trick for SSH to limit the number of accepted port redirection connections. This makes the window of time the untrusted local user can connect to the tunnel much smaller. Enable it via Options -> Advanced -> "SSH Local Port Protections". You will need to have the lim_accept.so file in your SSVNC package. The main message is to 'Watch your Back' when you connect via the SSVNC tunnels and there are users you don't trust on your workstation. The same applies to ANY use of SSH '-L' port redirections or outgoing stunnel SSL redirection services. Help and Info: ------------- For more help on other options and usage patterns run these: ./bin/ssvnc_cmd -h ./bin/util/ss_vncviewer -h See also: http://www.karlrunge.com/x11vnc http://www.karlrunge.com/x11vnc/faq.html x11vnc -h | more http://stunnel.mirt.net http://www.stunnel.org http://www.openssl.org http://www.tightvnc.com http://www.realvnc.com http://www.chiark.greenend.org.uk/~sgtatham/putty/ http://sourceforge.net/projects/cotvnc/ x11vnc-0.9.17/misc/enhanced_tightvnc_viewer/Windows/000077500000000000000000000000001500463450600223545ustar00rootroot00000000000000x11vnc-0.9.17/misc/enhanced_tightvnc_viewer/Windows/README.txt000066400000000000000000000056231500463450600240600ustar00rootroot00000000000000 This is a Windows utility to automatically start up STUNNEL to redirect SSL VNC connections to a remote host. Then TightVNC Viewer (included) is launched to use this SSL tunnel. An example server would be "x11vnc -ssl", or any VNC server with a 2nd STUNNEL program running on the server side. Just click on the program "ssvnc.exe", and then enter the remote VNC Server and click "Connect". Click on "Help" for more information information. You can also set some simple options under "Options ..." If you want that application to run in "SSH-ONLY" mode, click on the "sshvnc.bat" wrapper instead. Or enter SSH_ONLY. Note that on Windows when the TightVNC viewer disconnects you may need to terminate the STUNNEL program manually. To do this: Click on the STUNNEL icon (dark green) on the System Tray and then click "Exit". Before that, however, you will be prompted if you want ssvnc.exe to try to terminate STUNNEL for you. (Note that even if STUNNEL termination is successful, the Tray Icon may not go away until the mouse hovers over it!) With this STUNNEL and TightVNC Viewer wrapper you can also enable using SSL Certificates with STUNNEL, and so the connection is not only encrypted but it is also not susceptible to man-in-the-middle attacks. See the STUNNEL and x11vnc documentation for how to create and add SSL Certificates (PEM files) for authentication. Click on the "Certs ..." button to specify the certificate(s). See the Help there for more info and also: http://www.karlrunge.com/x11vnc http://www.tightvnc.com http://www.stunnel.org http://www.openssl.org http://www.chiark.greenend.org.uk/~sgtatham/putty/ You can use x11vnc to create certificates if you like: http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-ca Misc: The openssl.exe stunnel.exe vncviewer.exe libeay32.dll libssl32.dll programs came from the websites mentioned above. IMPORTANT: some of these binaries may have cryptographic software that you may not be allowed to download or use. See the above websites for more information and also the util/info subdirectories. Also, the kill.exe and tlist.exe programs in the w98 directory came from diagnostic tools ftp site of Microsoft's. Important Note for Windows Vista: One user reports that on Windows Vista if you move or extract the "ssvnc" folder down to the "Program Files" folder you will be prompted to do this as the Administrator. But then when you start up ssvnc, as a regular user, it cannot create files in that folder and so it fails to run properly. We recommend to not copy or extract the "ssvnc" folder into "Program Files". Rather, extract it to somewhere you have write permission (e.g. C:\ or your User dir) and create a Shortcut to ssvnc.exe on the desktop. If you must put a launcher file down in "Program Files", perhaps an "ssvnc.bat" that looks like this: C: cd \ssvnc\Windows ssvnc.exe x11vnc-0.9.17/misc/enhanced_tightvnc_viewer/Windows/sshvnc.bat000066400000000000000000000000601500463450600243440ustar00rootroot00000000000000start ssvnc.exe -ssh %1 %2 %3 %4 %5 %6 %7 %8 %9 x11vnc-0.9.17/misc/enhanced_tightvnc_viewer/Windows/tsvnc.bat000066400000000000000000000000571500463450600242030ustar00rootroot00000000000000start ssvnc.exe -ts %1 %2 %3 %4 %5 %6 %7 %8 %9 x11vnc-0.9.17/misc/enhanced_tightvnc_viewer/Windows/util/000077500000000000000000000000001500463450600233315ustar00rootroot00000000000000x11vnc-0.9.17/misc/enhanced_tightvnc_viewer/Windows/util/connect_br.tcl000077500000000000000000000646331500463450600261700ustar00rootroot00000000000000#!/usr/bin/wish proc check_callback {} { global debug if {$debug} { puts stderr "." } check_closed after 1000 check_callback } proc getout {} { global client_fh server_fh set delay 50 catch {flush $client_fh} after $delay catch {close $client_fh} set client_fh "" after $delay catch {flush $server_fh} after $delay catch {close $server_fh} set server_fh "" after $delay global bmesg_cnt if [info exists bmesg_cnt] { catch {tkwait window .bmesg$bmesg_cnt} } destroy . exit } proc check_closed {} { global got_connection debug global client_fh server_fh if {! $got_connection} { return } if {$client_fh != ""} { set ef "" catch {set ef [eof $client_fh]} if {$ef == 1} { if {$debug} { puts stderr "client_fh EOF" } getout } } if {$server_fh != ""} { set ef "" catch {set ef [eof $server_fh]} if {$ef == 1} { if {$debug} { puts stderr "server_fh EOF" } getout } } } proc xfer_in_to_out {} { global client_fh server_fh debug do_bridge if {$client_fh != "" && ![eof $client_fh]} { set ef "" catch {set ef [eof $client_fh]} if {$ef == 0} { set str "" catch {set str [read $client_fh 4096]} if {$debug} { #puts stderr "xfer_in_to_out: $str" puts stderr "xfer_in_to_out: [string length $str]" } if {$server_fh != "" && $str != ""} { catch {puts -nonewline $server_fh $str} catch {flush $server_fh} } } } check_closed } proc xfer_out_to_in {} { global client_fh server_fh debug do_bridge if {$server_fh != ""} { set ef "" catch {set ef [eof $server_fh]} if {$ef == 0} { set str "" catch {set str [read $server_fh 4096]} if {$debug} { #puts stderr "xfer_out_to_in: $str" puts stderr "xfer_out_to_in: [string length $str]" } if {$client_fh != "" && $str != ""} { catch {puts -nonewline $client_fh $str} catch {flush $client_fh} } } } check_closed } proc bmesg {msg} { global env if {!

SYNOPSIS ssvnc ssvnc [host][:display] ssvnc [saved-profile-name] ssvnc [options] [host-or-profile] ssvnc -cmd [ssvnc_cmd-args] ssvnc --help DESCRIPTION ssvnc is a tcl/tk gui wrapper that runs on Unix, MacOSX, and Windows. It sets up an SSL or SSH tunnel to the remote VNC Server and then launches the VNC viewer (either the one provided or another one that you have specified) to use that encrypted tunnel to connect to the VNC Server. The use of Proxies and Gateways to make the connections is implemented. OPTIONS -help, -h Print this help. --help Starts up the GUI as though the 'Help' button was pressed to show the main Help panel. -cmd [ssvnc_cmd-args] Launch the ssvnc_cmd utility command directly (no GUI) with the given arguments (for use when ssvnc_cmd is not in one's PATH.) If neither ssvnc_cmd nor ssvncviewer is in PATH, one can launch the viewer directly via: ssvnc -cmd -viewer [viewer-args] -profiles List the saved SSVNC profiles you have created. A profile is a destination host with specific parameter settings. -list Same as -profiles -ssh Start in "SSH Only Mode". No SSL aspects are shown. Same as running the command sshvnc -ts Start in "Terminal Services Mode". This is like "SSH Only Mode", but simpler and assumes x11vnc is available on the remote side to start and manage X and VNC sessions. Same as running the command tsvnc -tso Same as -ts "Terminal Services Mode", however never let the user leave this mode (no button to switch modes is provided.) Same as SSVNC_TS_ALWAYS=1. -ssl Force the full GUI Mode: both SSL and SSH. This is the default. Same as -ss. -nv Toggle the "Verify All Certs" button to be off at startup. -nvb Never show the "Verify All Certs" button. Same as SSVNC_NO_VER- IFY_ALL_BUTTON=1. -bigger Make the Profile Selection Dialog window bigger. Same as SSVNC_BIGGER_DIALOG=1. -noenc Start off in a mode where a 'No Encryption' check button is present. You can toggle the mode with Ctrl-E. Same as SSVNC_DISABLE_ENCRYPTION_BUTTON=1. Or noenc=1 in ~/.ssvncrc. Selecting no encryption is the same as the vnc:// and Vnc:// prefixes described below. The -noenc mode is now the default, use -enc or noenc=0 for the opposite behavior. -killstunnel On Windows, automatically terminate the STUNNEL process when the viewer exits instead of prompting you (same as killstunnel=1 in ssvnc_rc or toggle in Options menu) -nokillstunnel On Windows, disable -killstunnel mode. Same as killstunnel=0 in ssvnc_rc or toggle in Options menu. Note that -killstunnel mode is now the default. -mycert /path/to/mycert.pem Set the default "MyCert" to be /path/to/mycert.pem. Same as -cert. If the file does not exist, ~/.vnc/certs is prefixed and tried. You can also set mycert=/path/to/mycert.pem in ~/.ssvncrc -cacert /path/to/cacert.crt Set the default "ServerCert" to be /path/to/cacert.crt. Same as -ca. If the file does not exist, ~/.vnc/certs is prefixed and tried. You can also set cacert=/path/to/cacert.crt in ~/.ssvncrc -crl /path/to/mycrl.pem Set the default Certificate Revocation List to be /path/to/mycrl.pem. If the file does not exist, ~/.vnc/certs is prefixed and tried. You can also set crl=/path/to/mycrl.pem in ~/.ssvncrc.

On ssvnc 1.0.27 and # later the bundled command 'ultravnc_dsm_helper' is used. # # See http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-ca for details on # SSL certificates with VNC. # # A few other args (not related to SSL and certs): # # -2nd Run the vncviewer a 2nd time if the first connections fails. # # -ssh Use ssh instead of stunnel SSL. ssh(1) must be installed and you # must be able to log into the remote machine via ssh. # # In this case "host:display" may be of the form "user@host:display" # where "user@host" is used for the ssh login (see ssh(1) manpage). # # If -proxy is supplied it can be of the forms: "gwhost" "gwhost:port" # "user@gwhost" or "user@gwhost:port". "gwhost" is an incoming ssh # gateway machine (the VNC server is not running there), an ssh -L # redir is used to "host" in "host:display" from "gwhost". Any "user@" # part must be in the -proxy string (not in "host:display"). # # Under -proxy use "gwhost:port" if connecting to any ssh port # other than the default (22). (even for the non-gateway case, # -proxy must be used to specify a non-standard ssh port) # # A "double ssh" can be specified via a -proxy string with the two # hosts separated by a comma: # # [user1@]host1[:port1],[user2@]host2[:port2] # # in which case a ssh to host1 and thru it via a -L redir a 2nd # ssh is established to host2. # # Examples: # # ss_vncviewer -ssh bob@bobs-home.net:0 # ss_vncviewer -ssh -sshcmd 'x11vnc -localhost' bob@bobs-home.net:0 # # ss_vncviewer -ssh -proxy fred@mygate.com:2022 mymachine:0 # ss_vncviewer -ssh -proxy bob@bobs-home.net:2222 localhost:0 # # ss_vncviewer -ssh -proxy fred@gw-host,fred@peecee localhost:0 # # -sshcmd cmd Run "cmd" via ssh instead of the default "sleep 15" # e.g. -sshcmd 'x11vnc -display :0 -localhost -rfbport 5900' # # -sshargs "args" pass "args" to the ssh process, e.g. -L/-R port redirs. # # -sshssl Tunnel the SSL connection thru a SSH connection. The tunnel as # under -ssh is set up and the SSL connection goes thru it. Use # this if you want to have and end-to-end SSL connection but must # go thru a SSH gateway host (e.g. not the vnc server).

You MUST be able to log in via SSH to the remote terminal server. Ask your administrator to set this up for you if it isn't already. x11vnc must also be installed on the remote server machine. See "Requirements" below. This mode is started by the commands 'tsvnc' or 'ssvnc -ts' or toggled by pressing Ctrl-t. "SSVNC Mode" under Options -> Advanced will also return to the full SSVNC. Or in your ~/.ssvncrc (or ~/ssvnc_rc on Windows) put "mode=tsvnc" to have the tool always start up in that mode. To constrain the UI, run with -tso or SSVNC_TS_ALWAYS set to prevent leaving the Terminal Services mode. Hosts and Displays: Enter the remote VNC Terminal Services hostname in the 'VNC Terminal Server' entry. Examples: 24.67.132.27 far-away.east fred@someplace.no Then click on "Connect". Once the SSH is running (you may need to type a password or accept a new ssh key in the terminal window that pops up), the VNC Viewer will be automatically started directed to the local port of the SSH tunnel which, in turn, encrypts and redirects the connection to the remote VNC server. x11vnc is run remotely to find or create your terminal services desktop session. It must be installed and accessible on the remote system. Enter "user@hostname.com" in 'VNC Terminal Server' if the remote username is different from the yours on this machine. On Windows you *MUST* supply the remote username due to a deficiency in Plink. This entry is passed to SSH; it could also be an SSH alias you have created (in ~/.ssh/config). If the remote SSH server is run on a non-standard port, e.g. 2222, use something like one of these: far-away.east:2222 fred@someplace.no:2222 (unlike SSVNC mode, the number is the SSH port, not the VNC display) If you find yourself in the unfortunate circumstance that your ssh username has a space in it, use %SPACE (or %TAB) like this: fred%SPACEflintstone@xyzzy.net Zeroconf/Bonjour: On Unix or Mac OS X, if the 'avahi-browse' or 'dns-sd' command is available on the system and in your PATH, a 'Find' button is placed by 'VNC Host:Display'. Clicking on Find will try to find VNC Servers on your Local Network that advertize via the Zeroconf protocol. A menu of found hosts is presented for you to select from. Profiles: Use "Save" to save a profile (i.e. a host:display and its specific settings) with a name. The "TS-" prefix will be suggested to help you distinguish between Terminal Services and regular profiles. To load in a saved Options profile, click on the "Load" button, and choose which one you want. To list your profiles from the command line use: tsvnc -profiles (or -list) To launch profile1 directly from the command-line, or to a server use things like: tsvnc profile1 tsvnc /path/to/profile1.vnc tsvnc hostname tsvnc user@hostname Note that the 'Verify All Certs' setting is NOT saved in profiles. Proxies/Gateways: Proxy/Gateway is usually a gateway machine to log into via SSH that is not the machine running the VNC terminal services. However, Web and SOCKS proxies can also be used (see below). For example if a company had a central login server: "ssh.company.com" (accessible from the internet) and the internal server name was "ts-server", one could put in VNC Terminal Server: ts-server Proxy/Gateway: ssh.company.com It is OK if the hostname "ts-server" only resolves inside the firewall. The 2nd host, ts-server in this example, MUST also be running an SSH server and you must be able to log into it. You may need to supply a 2nd password to it to login. Use username@host (e.g. joe@ts-server or jsmith@ssh.company.com) if the user name differs between machines. NOTE: On Windows you MUST always supply the username@ because putty's plink requires it. NON-STANDARD SSH PORT: To use a non-standard ssh port (i.e. a port other than 22) you need to use the Proxy/Gateways as well. E.g. something like this for port 2222: VNC Terminal Server: ts-server Proxy/Gateway: jsmith@ssh.company.com:2222 On Unix/MacOSX the username@ is not needed if it is the same as on this machine. A Web or SOCKS proxy can also be used. Use this if you are inside a firewall that prohibits direct connections to remote SSH servers. In Terminal Services SSH mode, the "http://" prefix is required for web proxies. VNC Terminal Server: fred@someplace.no Proxy/Gateway: http://myproxy.west:8080 or for SOCKS: VNC Terminal Server: fred@someplace.no Proxy/Gateway: socks://mysocks.west:1080 use socks5://... to force the SOCKS5 version. For a non-standard port the above would be, e.g., fred@someplace.no:2222 As with a username that contains a space, use %SPACE (or %TAB) to indicate it in the SSH proxies, e.g. john%SPACEsmith@ssh.company.com One can also chain proxies and other things. See the section "SSH Proxies/Gateways" in the Main SSVNC Help for full details.

On Windows a plink/putty binary is included. On the remote VNC Terminal Services host, x11vnc must be installed (0.9.3 or higher), and at least one virtual X server: Xvfb, Xdummy, or Xvnc must be available. Xvfb is the most often used one. All of these programs must be available in $PATH on the remote server when logged in via SSH. The VNC terminal services administrator can make "x11vnc" be a wrapper script that sets everything up correctly and then runs the real x11vnc. Real X servers: As a *BONUS*, if on the remote host, say a workstation, you have a regular X session running on the physical hardware that you are ALREADY logged into you can access to that display as well (x11vnc will find it). So this tool can be used as a simple way to launch x11vnc to find your real X display on your workstation and connect to it. The Printing and Sound redirection won't work for this mode however. You will need to use the full SSVNC application to attempt that. If you (mistakenly) have not logged into an X session on the real X server on the workstation, a VIRTUAL (Xvfb, etc.) server will be created for you (that may or may not be what you want). The X Login Advanced setting can be used to connect to a X Display Manger Greeter login panel (no one is logged in yet). This requires sudo(1) privileges on the remote machine.

It is of the form "host:number", where "host" is the hostname of the machine running the VNC Server and "number" is the VNC display number; it is often "0". Some Examples: snoopy:0 far-away.east:0 sunray-srv1.west:17 24.67.132.27:0 Then click on "Connect". When you do the STUNNEL program will be started locally to provide you with an outgoing SSL tunnel. Once the STUNNEL is running, the TightVNC Viewer (Or perhaps Chicken of the VNC on Mac OS X, or one you set under Options) will be automatically started and directed to the local port of the SSL tunnel which, in turn, encrypts and redirects the connection to the remote VNC server. The remote VNC server **MUST** support an initial SSL/TLS handshake before using the VNC protocol (i.e. VNC is tunnelled through the SSL channel after it is established). "x11vnc -ssl ..." does this, and any VNC server can be made to do this by using, e.g., STUNNEL or socat on the remote side. SSVNC also supports VeNCrypt and ANONTLS SSL/TLS VNC servers (see below.) * Automatic SSH Tunnels are described below. * The 'No Encryption' / 'None' option provides a direct connection without encryption (disable the button with the -enc option, or Options menu.) More info in Tip 5. Port numbers: If you are using a port less than the default VNC port 5900 (usually the VNC display = port - 5900), use the full port number itself, e.g.: 24.67.132.27:443 Note, however, if the number n after the colon is < 200, then a port number 5900 + n is assumed; i.e. n is the VNC display number. If you must use a TCP port less than 200, specify a negative value, e.g.: 24.67.132.27:-80 For Reverse VNC connections (listening viewer, See Tip 2 and Options -> Help), the port mapping is similar, except "listening display :0" corresponds to port 5500, :1 to 5501, etc. Specify a specific interface, e.g. 192.168.1.1:0 to have stunnel listen on that interface only. Listening on IPv6 can also be done, use e.g. :::0 or ::1:0 This listening on IPv6 (:::0) works for UN-encrypted reverse connections as well (mode 'None'). Zeroconf/Bonjour: On Unix or Mac OS X, if the 'avahi-browse' or 'dns-sd' command is available on the system and in your PATH, a 'Find' button is placed by 'VNC Host:Display'. Clicking on Find will try to find VNC Servers on your Local Network that advertize via the Zeroconf protocol. A menu of found hosts is presented for you to select from. VNC Password: On Unix or MacOSX IF there is a VNC password for the server you can enter it in the "VNC Password:" entry box. This is *REQUIRED* on MacOSX when Chicken of the VNC is used, because that viewer does not put up a user password prompt when it learns that a password is needed. On Unix (including MacOSX using the X11 viewer) if you choose not to enter the password you will simply be prompted for it in the terminal window running TightVNC viewer if one is required. On Windows TightVNC viewer will prompt you if a password is required. NOTE: when you Save a VNC profile, the password is NOT saved (you need to enter it each time). Nor is the 'Verify All Certs' setting. Profiles: Use "Save" to save a profile (i.e. a host:display and its specific settings) with a name. To load in a saved Options profile, click on the "Load" button. To list your profiles from the command line use: ssvnc -profiles (or -list) You can launch ssvnc and have it immediately connect to the server by invoking it something like this: ssvnc profile1 (launches profile named "profile1") ssvnc /path/to/profile.vnc (loads the profile file, no launching) ssvnc hostname:0 (connect to hostname VNC disp 0 via SSL) ssvnc vnc+ssl://hostname:0 (same) ssvnc vnc+ssh://hostname:0 (connect to hostname VNC disp 0 via SSH) see the Tips 5 and 7 for more about the URL-like syntax. If you don't want "ssvnc profile1" to immediately launch the connection to the VNC server set the SSVNC_PROFILE_LOADONLY env. var. to 1. (or specify the full path to the profile.vnc as shown above.) SSL Certificate Verification: *** IMPORTANT ***: If you do not take the steps to VERIFY the VNC Server's SSL Certificate, you are in principle vulnerable to a Man-In-The-Middle attack. Without SSL Certificate verification, only passive network sniffing attacks will be guaranteed to be prevented. There are hacker tools like dsniff/webmitm and cain that implement SSL Man-In-The-Middle attacks. They rely on the client user not bothering to check the cert. Some people may be confused by the above because they are familiar with their Web Browser using SSL (i.e. https://... websites) and those sites are authenticated securely without the user's need to verify anything manually. The reason why this happens automatically is because 1) their web browser comes with a bundle of Certificate Authority certificates and 2) the https sites have paid money to the Certificate Authorities to have their website certificate signed by them. When using SSL in VNC we normally do not do something this sophisticated, and so we have to verify the certificates manually. However, it is possible to use Certificate Authorities with SSVNC; that method is described below. You can use the "Fetch Cert" button to retrieve the Cert and then after you check it is OK (say, via comparing the MD5 or other info) you can "Save" it and use it to verify future connections to servers. (However, see the note at the end of this section about CA certificates.) When "Verify All Certs" is checked, this check is always enforced, and so the first time you connect to a new server you may need to follow a few dialogs to inspect and save the server certificate. See the "Certs... -> Help" for information on how to manage certificates. "Verify All Certs" is on by default. Note, however, "Fetch Cert" and "Verify All Certs" are currently disabled in the very rare "SSH + SSL" usage mode to avoid SSHing in twice. You can manually set a ServerCert or CertsDir in this case if you like. Advanced Method: Certificate Authority (CA): If you, or your site administrator, goes though the steps of setting up a Certificate Authority (CA) to sign the VNC server and/or VNC client Certs, that can be used instead and avoids the need to manually verify every cert while still authenticating every connection. More info: http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-ca See the cmdline option -cacert file below in 'SSL Certificates' for setting a default ServerCert/CA Cert. You may also Import the CA Cert and save it to the 'Accepted Certs' directory so the "Verify All Certs" automatic checking will find it. Note that if a Server is using a CA signed certificate instead of its own Self-Signed one, then the default "Verify All Certs/Fetch Cert" saving mechanism will NOT succeed. You must obtain the CA certificate and explicitly set it as the ServerCert or Import it to Accepted Certs. SSL/TLS Variants; VeNCrypt and ANONTLS: SSVNC can also connect to VNC SSL/TLS variants; namely the VeNCrypt and "TLS" VNC Security types. Vino uses the latter (we call it "ANONTLS"); and a growing number use VeNCrypt (QEMU, ggi, virt-manager, VeNCrypt, Xen.) Via the VeNCrypt bridge that SSVNC provides, the VeNCrypt/ANONTLS support ALSO works with ANY 3rd party VNC Viewers you specify via 'Change VNC Viewer' (e.g. RealVNC, TightVNC, UltraVNC, etc.) that do not directly support VeNCrypt or ANONTLS. This works on all platforms: Unix, MacOSX, and Windows. Notes on VeNCrypt/ANONTLS Auto-detection: IMPORTANT: VeNCrypt Server Auto-detection *ONLY* occurs in SSL mode and when an initial fetch-cert action takes place. While the initial certificate fetch is taking place SSVNC applies heuristics to try to automatically detect the VeNCrypt or ANONTLS protocol use by the VNC server. This way it learns that the server is using it and then knows to switch to VeNCrypt encrypted SSL/TLS at the right point. Then SSVNC makes a second (the real) connection to VNC server and connects the VNC viewer to it. In the default "Verify All Certs" mode, a fetch cert action always takes place, and so VeNCrypt/ANONTLS will be autodected. However, if you have specified an explicit ServerCert or disabled "Verify All Certs" then even though the initial fetch cert action is no longer needed, it is performed anyway because it allows VeNCrypt/ANONTLS auto-detection. To disabled this initial fetch (e.g. you know the VNC server is normal SSL and not VeNCrypt/ANONTLS and want to connect more quickly) then select "Do not Probe for VeNCrypt" in the Advanced Options menu. On the other hand, if you know the VNC server ONLY supports VeNCrypt or ANONTLS, to improve the accuracy and speed with which the connection takes place, you can specify the one or both of the 'Server uses VeNCrypt SSL encryption' and 'Server uses Anonymous Diffie-Hellman' in the 'Advanced' options panel. That way guessing via an initial probe is not needed or performed. See each options's Advanced Options Help for more info. Note that if you are using VeNCrypt or ANONTLS for REVERSE connections (Listen) then you *MUST* set the 'Server uses VeNCrypt SSL encryption' (and the ANON-DH if it applies) option in Advanced. Note also that REVERSE VeNCrypt and ANONTLS connections currently do not work on Windows. Also, if you are using the "Use SSH+SSL" double tunnel, you MUST set 'Server uses VeNCrypt SSL encryption' (and the ANON-DH if it applies) because the initial fetch cert is disabled in SSH+SSL mode. Deciphering SSL Negotiation Success or Failure: Since SSVNC is a "glue program", in this case gluing VNCViewer and stunnel together (with possibly a proxy helper) reporting is clumsy at best. (In SSH encryption mode, it glues to ssh instead of stunnel.) In most cases the programs being "glued" are run in a terminal window where you can see the program's output. On Windows you will need to double click on the stunnel tray icon to view its log. Although the output is quite cryptic, you are encouraged to learn to recognize some of the errors reported in it. Here is stunnel output for a case of successfully verifying the VNC Server's Certificate: 2008.11.20 08:09:39 LOG5[1472]: VERIFY OK: depth=0, /C=AU/L=... 2008.11.20 08:09:39 LOG6[1472]: SSL connected: new session negotiated 2008.11.20 08:09:39 LOG6[1472]: Negotiated ciphers: AES256-SHA SSLv3 ...

Also in the output will be messages about whether the SSL VNC server rejected your connection because it requires you to authenticate yourself with a certificate (MyCert). Here is the case when you supplied no MyCert: 2008.11.20 08:16:29 LOG3[1746]: SSL_connect: 14094410: error:14094410: SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure or you used a certificate the server did not recognize: 2008.11.20 08:18:46 LOG3[1782]: SSL_connect: 14094412: error:14094412: SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate or your certificate has been revoked: 2008.11.20 08:20:08 LOG3[1913]: SSL_connect: 14094414: error:14094414: SSL routines:SSL3_READ_BYTES:sslv3 alert certificate revoked SSH: Click on "Use SSH" if you want to use an *SSH* tunnel instead of SSL (then the VNC Server does not need to speak SSL or use STUNNEL or socat). You will need to be able to login to your account on the remote host via SSH (e.g. via password, ssh keys, or ssh-agent). Specify the SSH hostname and VNC display in the VNC Host:Display entry. Use something like: username@far-away.east:0 if your remote username is different from the one on the local viewer machine. On Windows you *MUST* supply the "username@" part because Putty/Plink needs it to work correctly. "SSH + SSL" is similar but its use is more rare because it requires 2 encrypted tunnels to reach the VNC server. See the Help under Options for more info. To connect to a non-standard SSH port, see SSH Proxies/Gateways section. See Tip 8) for how to make this application be SSH-only with the -ssh command line option or "sshvnc". If you find yourself in the unfortunate circumstance that your ssh username has a space in it, use %SPACE (or %TAB) like this: fred%SPACEflintstone@xyzzy.net:0 Remote SSH Command: In SSH or SSH + SSL mode you can also specify a remote command to run on the remote ssh host in the "Remote SSH Command" entry. The default is just to sleep a bit (e.g. sleep 15) to make sure the tunnel ports are established. Alternatively you could have the remote command start the VNC server, e.g. x11vnc -display :0 -rfbport 5900 -localhost -nopw When starting the VNC server this way, note that sometimes you will need to correlate the VNC Display number with the "-rfbport" (or similar) option of the server. E.g. for VNC display :2 VNC Host:Display username@somehost.com:2 Remote SSH Command: x11vnc -find -rfbport 5902 -nopw See the Tip 18) for using x11vnc PORT=NNNN feature (or vncserver(1) output) to not need to specify the VNC display number or the x11vnc -rfbport option. Windows SSH SERVER: if you are ssh'ing INTO Windows (e.g. CYGWIN SSHD server) there may be no "sleep" command so put in something like "ping localhost" or "ping -n 10 -w 1000 localhost" to set a short delay to let the tunnel ports get established. SSL Certificates: If you want to use a SSL Certificate (PEM) file to authenticate YOURSELF to the VNC server ("MyCert") and/or to verify the identity of the VNC Server ("ServerCert" or "CertsDir") select the certificate file by clicking the "Certs ..." button before connecting. Certificate verification is needed to prevent Man-In-The-Middle attacks; if it is not done then only passive network sniffing attacks are prevented. There are hacker tools like dsniff/webmitm and cain that implement SSL Man-In-The-Middle attacks. They rely on the client user not bothering to check the cert. See the x11vnc documentation: http://www.karlrunge.com/x11vnc/ssl.html for how to create and use PEM SSL certificate files. An easy way is: x11vnc -ssl SAVE ... where it will print out its automatically generated certificate to the screen and that can be copied safely to the viewer side. You can also use the "Create Certificate" feature of this program under "Certs ...". Just click on it and follow the instructions in the dialog. Then copy the cert file to the VNC Server and specify the other one in the "Certs ..." dialog. Alternatively you can use the "Import Certificate" action to paste in a certificate or read one in from a file. Or you can use the "Fetch Cert" button on the main panel. If "Verify All Certs" is checked, you will be forced to check Certs of any new servers the first time you connect. Note that "Verify All Certs" is on by default so that users who do not understand the SSL Man-In-The-Middle problem will not be left completely vulnerable to it (everyone still must make the effort to verify new certificates by an external method to be completely safe). To have "Verify All Certs" toggled off at startup, use "ssvnc -nv" or set SSVNC_NO_VERIFY_ALL=1 before starting. If you do not even want to see the button, use "ssvnc -nvb" or SSVNC_NO_VERIFY_ALL_BUTTON=1. Use the "-mycert file" option (same as "-cert file") to set a default MyCert. This is the same as "mycert=file" (also "cert=file") in the ~/.ssvncrc file. See Certs -> Help for more info. Use the "-cacert file" option (same as "-ca file") to set a default ServerCert (or CA). This is the same as "cacert=file" (also "ca=file") in the ~/.ssvncrc file. See Certs -> Help for more info. Use the "-crl file" option to set a default CRL File. This is the same as "crl=file" in the ~/.ssvncrc file. See Certs -> Help for more info. Prefix any of these files with "FORCE:" to make them immutable. More Options: To set other Options, e.g. for View-Only usage or to limit the number of colors used, click on the "Options ..." button and read the Help there. More Info: Press the 'Proxies', 'Misc', and 'Tips' buttons below. See also these links for more information: http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-tunnel-ext http://stunnel.mirt.net http://www.tightvnc.com } set help_misc { Windows STUNNEL problems: Note that on Windows when the Viewer connection is finished by default SSVNC will try to kill the STUNNEL process for you. If Options -> Kill Stunnel Automatically is not set you will be prompted if you want SSVNC to try to kill the STUNNEL process for you. Usually you will say Yes, however if there are problems connecting you may want to look at the STUNNEL Log first. Before it is killed, double clicking the STUNNEL tray icon (dark green) will show you its Log file (useful for debugging connection problems). Even though SSVNC will kill the STUNNEL process for you, you will still need to move the mouse over the icon to make the little picture go away!!! This is unfortunate but there does not seem to be a way to avoid it. In some cases you may need to terminate STUNNEL manually from the System Tray (right click on dark green icon) and selecting "Exit". Use -nokillstunnel or killstunnel=0 in ~/.ssvncrc to have SSVNC start up with stunnel killing disabled. Untrusted Local Users: *IMPORTANT WARNING*: If you run SSVNC on a workstation or computer that other users can log into and you DO NOT TRUST these users (it is a shame but sometimes one has to work in an environment like this), then please note the following warning. By 'do not trust' we mean they might try to gain access to remote machines you connect to via SSVNC. Note that an untrusted local user can often obtain root access in a short amount of time; if a user has achieved that, then all bets are off for ANYTHING that you do on the workstation. It is best to get rid of Untrusted Local Users as soon as possible. Both the SSL and SSH tunnels set up by SSVNC listen on certain ports on the 'localhost' address and redirect TCP connections to the remote machine; usually the VNC server running there (but it could also be another service, e.g. CUPS printing). These are the stunnel(8) SSL redirection and the ssh(1) '-L' port redirection. Because 'localhost' is used only users or programs on the same workstation that is running SSVNC can connect to these ports, however this includes any local users (not just the user running SSVNC.) If the untrusted local user tries to connect to these ports, he may succeed by varying degrees to gain access to the remote machine. We now list some safeguards one can put in place to try to make this more difficult to achieve. It probably pays to have the VNC server require a password, even though there has already been SSL or SSH authentication (via certificates or passwords). In general if the VNC Server requires SSL authentication of the viewer that helps, unless the untrusted local user has gained access to your SSVNC certificate keys. If the VNC server is configured to only allow one viewer connection at a time, then the window of opportunity that the untrusted local user can use is greatly reduced: he might only have a second or two between the tunnel being set up and the SSVNC vncviewer connecting to it (i.e. if the VNC server only allows a single connection, the untrusted local user cannot connect once your session is established). Similarly, when you disconnect the tunnel is torn down quickly and there is little or no window of opportunity to connect (e.g. x11vnc in its default mode exits after the first client disconnects). Also for SSL tunnelling with stunnel(8) on Unix using one of the SSVNC prebuilt 'bundles', a patched stunnel is provided that denies all connections after the first one, and exits when the first one closes. This is not true if the system installed stunnel(8) is used and is not true when using SSVNC on Windows. The following are experimental features that are added to SSVNC to improve the situation for the SSL/stunnel and SSH cases. Set them via Options -> Advanced -> "STUNNEL Local Port Protections" or "SSH Local Port Protections". STUNNEL: 1) For SSL tunnelling with stunnel(8) on Unix there is a setting 'Use stunnel EXEC mode' that will try to exec(2) stunnel instead of using a listening socket. This will require using the specially modified vncviewer unix viewer provided by SSVNC. The mode works well and is currently set as the default. Disable it if it causes problems or conflicts. 2) For SSL tunnelling with stunnel(8) on Unix there is a setting 'Use stunnel IDENT check' (experimental) to limit socket connections to be from you (this assumes the untrusted local user has not become root on your workstation and has modified your local IDENT check service; if he has you have much bigger problems to worry about...) Neither of the above methods are available on Windows. SSH: 1) There is also a simple LD_PRELOAD trick for SSH to limit the number of accepted port redirection connections. This makes the window of time the untrusted local user can connect to the tunnel much smaller. Enable it via Options -> Advanced -> "SSH Local Port Protections". You will need to have the lim_accept.so file in your SSVNC package. The mode works well and is currently set as the default. Disable it if it causes problems or conflicts. The above method is not available on Windows. The main message is to 'Watch your Back' when you connect via the SSVNC tunnels and there are users you don't trust on your workstation. The same applies to ANY use of SSH '-L' port redirections or outgoing stunnel SSL redirection services. } set help_prox { Here are a number of long sections on all sorts of proxies, Web, SOCKS, SSH tunnels/gateways, UltraVNC, Single Click, etc., etc. Proxies/Gateways: If an intermediate proxy is needed to make the SSL connection (e.g. a web gateway out of a firewall) enter it in the "Proxy/Gateway" entry box: VNC Host-Display: host:number Proxy/Gateway: proxy-host:port e.g.: VNC Host-Display: far-away.east:0 Proxy/Gateway: myproxy.west:8080 If the "double proxy" case is required (e.g. coming out of a web proxied firewall environment and then INTO a 2nd proxy to ultimately reach the VNC server), separate them via a comma, e.g.: VNC Host-Display: far-away:0 Proxy/Gateway: myproxy.west:8080,myhome.net:443 So it goes: viewer -> myproxy.west -> myhome.net -> far-away (VNC) The proxies are assumed to be Web proxies. To use SOCKS proxies: VNC Host-Display: far-away.east:0 Proxy/Gateway: socks://mysocks.west:1080 Use socks5:// to force the SOCKS5 proxy protocol (e.g. for ssh -D). You can prefix web proxies with http:// in SSL mode but it doesn't matter since that is the default for a proxy. (NOTE that in SSH or SSH+SSL mode you MUST supply the http:// prefix for web proxies because in those modes an SSH tunnel is the default proxy type: see the next section.) Note that Web proxies are often configured to ONLY allow outgoing connections to ports 443 (HTTPS) and 563 (SNEWS), so you might have run the VNC server (or router port redirector) on those ports. SOCKS proxies usually have no restrictions on port number. You can chain up to 3 proxies (any combination of web (http://) and socks://) by separating them with commas (i.e. first,second,third). Proxies also work for un-encrypted connections ("None" or vnc://, Tip 5) See the ss_vncviewer description and x11vnc FAQ for info on proxies: http://www.karlrunge.com/x11vnc/faq.html#ss_vncviewer http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-java-viewer-proxy SSH Proxies/Gateways: Proxy/Gateway also applies to SSH mode, it is a usually a gateway SSH machine to log into via ssh that is not the workstation running the VNC server. However, Web and SOCKS proxies can also be used (see below). For example if a company had a central login server: "ssh.company.com" (accessible from the internet) and the internal workstation with VNC was named "joes-pc", then to create an SSH tunnel one could put this in: VNC Host:Display: joes-pc:0 Proxy/Gateway: ssh.company.com It is OK if the hostname "joes-pc" only resolves inside the firewall. The 2nd leg, from ssh.company.com -> joes-pc is done by a ssh -L redir and is not encrypted (but the viewer -> ssh.company.com 1st leg is an encrypted tunnel). To SSH encrypt BOTH legs, try the "double SSH gateway" method using the "comma" notation: VNC Host:Display: localhost:0 Proxy/Gateway: ssh.company.com,joes-pc this requires an SSH server also running on joes-pc. So an initial SSH login is done to ssh.company.com, then a 2nd SSH is performed (through port a redirection of the first) to login straight to joes-pc where the VNC server is running. Use username@host (e.g. joe@joes-pc jsmith@ssh.company.com) if the user names differ between the various machines. NOTE: On Windows you MUST always supply the username@ because putty's plink requires it. NON-STANDARD SSH PORT: To use a non-standard ssh port (i.e. a port other than 22) you need to use the Proxy/Gateways as well. E.g. something like this for port 2222: VNC Host:Display: localhost:0 Proxy/Gateway: joe@far-away.east:2222 On Unix/MacOSX the username@ is not needed if it is the same as on the client. This will also work going to a different internal machine, e.g. "joes-pc:0" instead of "localhost:0", as in the first example. A Web or SOCKS proxy can also be used with SSH. Use this if you are inside a firewall that prohibits direct connections to remote SSH servers. VNC Host:Display: joe@far-away.east:0 Proxy/Gateway: http://myproxy.west:8080 or for SOCKS: VNC Host:Display: joe@far-away.east:0 Proxy/Gateway: socks://mysocks.west:1080 Use socks5://... to force the SOCKS5 version. Note that the http:// prefix is REQUIRED for web proxies in SSH or SSH+SSL modes (but it is the default proxy type in SSL mode.) You can chain up to 3 proxies (any combination of http://, socks:// and ssh) by separating them with commas (i.e. first,second,third). Note: the Web and/or SOCKS proxies must come before any SSH gateways. For a non-standard SSH port and a Web or SOCKS proxy try: VNC Host:Display: localhost:0 Proxy/Gateway: http://myproxy.west:8080,joe@far-away.east:2222 Even the "double SSH gateway" method (2 SSH encrypted legs) described above works with an initial Web or SOCKS proxy, e.g.: VNC Host:Display: localhost:0 Proxy/Gateway: socks://mysocks.west:1080,ssh.company.com,joes-pc Some Notes on SSH localhost tunnelling with SSH options NoHostAuthenticationForLocalhost=yes and UserKnownHostsFile=file: Warning: Note that for proxy use with ssh(1), tunnels going through 'localhost' are used. This means ssh(1) thinks the remote hostname is 'localhost', which may cause collisions and confusion when storing and checking SSH keys. By default on Unix when a 'localhost' ssh host is involved the ssh option -o NoHostAuthenticationForLocalhost=yes is applied (see ssh_config(1) for details.) This avoids the warnings and ssh refusing to connect, but it reduces security. A man in the middle attack may be possible. SSVNC prints out a warning in the terminal every time the NoHostAuthenticationForLocalhost option is used. On Unix to disable the use of NoHostAuthenticationForLocalhost set the env. variable SSVNC_SSH_LOCALHOST_AUTH=1. This may induce extra ssh(1) dialogs. On Unix a MUCH SAFER and more convenient way to proceed is to set the known hosts option in Options -> Advanced -> 'Private SSH KnownHosts file' Then, only for the host in the current profile, a private known_hosts file will be used and so there will be no 'localhost' collisions. This method is secure (assuming you verify the SSH key fingerprint) and avoids the man in the middle attack. On Windows, Putty/Plink is used and does not have the UserKnownHosts or NoHostAuthenticationForLocalhost features. Keys are stored in the registry as localhost:port pairs and so it is possible to use the 'Port Slot' option to keep the keys separate to avoid the dialogs and also maintain good security. Note that for the "double SSH gateway" method the risk from using NoHostAuthenticationForLocalhost is significantly less because the first ssh connection does not use the option (it connects directly to the remote host) and the second one is only exposed for the leg inside the first gateway (but is still vulnerable there when NoHostAuthenticationForLocalhost is used.) As with a username that contains a space, use %SPACE (or %TAB) to indicate it in the SSH proxies, e.g. john%SPACEsmith@ssh.company.com UltraVNC Proxies/Gateways: UltraVNC has a "repeater" tool (http://www.uvnc.com/addons/repeater.html and http://koti.mbnet.fi/jtko/) that acts as a VNC proxy. SSVNC can work with both mode I and mode II schemes of this repeater. For Unix and MacOS X there is another re-implementation of the UltraVNC repeater: http://www.karlrunge.com/x11vnc/ultravnc_repeater.pl So one does not need to run the repeater on a Windows machine. Note that even though the UltraVNC repeater tool is NOT SSL enabled, it can nevertheless act as a proxy for SSVNC SSL connections. This is because, just as with a Web proxy, the proxy negotiations occur before the SSL traffic starts. (There is a separate UltraVNC tool, repeater_SSL.exe, that is SSL enabled and is discussed below.) Note: it seems only SSL SSVNC connections make sense with the UltraVNC repeater. SSH connections (previous section) do not seem to and so are not enabled to (let us know if you find a way to use it.) Unencrypted (aka Direct) SSVNC VNC connections (Vnc:// prefix in 'VNC Host:Display'; see Tip 5) also work with the UltraVNC repeater. MODE I REPEATER: For the mode I UltraVNC repeater the Viewer initiates the connection and passes a string that is the VNC server's IP address (or hostname) and port or display to the repeater (the repeater then makes the connection to the server host and then exchanges data back and forth.) To do this in SSVNC: VNC Host:Display: :0 Proxy/Gateway: repeater://myuvncrep.west:5900+joes-pc:1 Where "myuvncrep.west" is running the UltraVNC repeater and "joes-pc:1" is the VNC server the repeater will connect us to. Note here that the VNC Host:Display can be anything because it is not used; we choose :0. You cannot leave VNC Host:Display empty. The Proxy/Gateway format is repeater://proxy:port+vncserver:display. The string after the "+" sign is passed to the repeater server for it to interpret (and so does not have to be the UltraVNC repeater; you could create your own if you wanted to.) For this example, instead of joes-pc:1 it could be joes-pc:5901 or 192.168.1.4:1, 192.168.1.4:5901, etc. If you do not supply a proxy port, then the default 5900 is assumed, e.g. use repeater://myuvncrep.west+joes-pc:1 for port 5900 on myuvncrep.west then connecting to port 5901 on joes-pc. X11VNC: For mode I operation the VNC server x11vnc simply runs as a normal SSL/VNC server: x11vnc -ssl SAVE because the repeater will connect to it as a VNC client would. For mode II operation additional options are needed (see below.) MODE II REPEATER: For the mode II repeater both the VNC viewer and VNC server initiate TCP connections to the repeater proxy. In this case they pass a string that identifies their mutual connection via "ID:NNNN", for example: VNC Host:Display: :0 Proxy/Gateway: repeater://myuvncrep.west:5900+ID:2345 again, the default proxy port is 5900 if not supplied. And we need to supply a placeholder display ":0". The fact that BOTH the VNC viewer and VNC server initiate outgoing TCP connections to the repeater makes some things tricky, especially for the SSL aspect. In SSL one side takes the 'client' role and the other side must take the 'server' role. These roles must be coordinated correctly or otherwise the SSL handshake will fail. We now describe two scenarios: 1) SSVNC in Listening mode with STUNNEL in 'SSL server' role; and 2) SSVNC in Forward mode with STUNNEL in 'SSL client' role. For both cases we show how the corresponding VNC server x11vnc would be run. SSVNC Listening mode / STUNNEL 'SSL server' role: By default, when using SSL over a reverse connection the x11vnc VNC server will take the 'SSL client' role. This way it can connect to a standard STUNNEL (SSL server) redirecting connections to a VNC viewer in Listen mode. This is how SSVNC with SSL is normally intended to be used for reverse connections (i.e. without the UltraVNC Repeater.) To do it this way with the mode II UltraVNC Repeater; you set Options -> Reverse VNC Connection, i.e. a "Listening Connection". You should disable 'Verify All Certs' unless you have already saved the VNC Server's certificate to Accepted Certs. Or you can set ServerCert to the saved certificate. Then click 'Listen'. In this case an outgoing connection is made to the UltraVNC repeater, but everything else is as for a Reverse connection. Note that in Listening SSL mode you must supply a MyCert or use the "listen.pem" one you are prompted by SSVNC to create. X11VNC command: x11vnc -ssl -connect_or_exit repeater://myuvncrep.west+ID:2345 SSVNC Forward mode / STUNNEL 'SSL client' role: x11vnc 0.9.10 and later can act in the 'SSL server' role for Reverse connections (i.e. as it does for forward connections.) Set these x11vnc options: '-env X11VNC_DISABLE_SSL_CLIENT_MODE=1 -sslonly' The -sslonly option is to prevent x11vnc from thinking the delay in connection implies VeNCrypt instead of VNC over SSL. With x11vnc in X11VNC_DISABLE_SSL_CLIENT_MODE mode, you can then have SSVNC make a regular forward connection to the UltraVNC repeater. Note that SSVNC may attempt to do a 'Fetch Cert' action in forward connection mode to either retrieve the certificate or probe for VeNCrypt and/or ANONDH. After that 'Fetch Cert' is done the connection to the UltraVNC repeater will be dropped. This is a problem for the subsequent real VNC connection. You can disable 'Verify All Certs' AND also set 'Do not Probe for VeNCrypt' to avoid the 'Fetch Cert' action. Or, perhaps better, add to x11vnc command line '-connect_or_exit repeater://... -loop300,2' (in addition to the options in the previous paragraphs.) That way x11vnc will reconnect once to the Repeater after the 'Fetch Cert' action. Then things should act pretty much as a normal forward SSL connection. X11VNC 0.9.10 command (split into two lines): x11vnc -ssl -connect_or_exit repeater://myuvncrep.west+ID:2345 \ -env X11VNC_DISABLE_SSL_CLIENT_MODE=1 -loop300,2 -sslonly We recommend using "SSVNC Forward mode / STUNNEL 'SSL client' role" if you are connecting to x11vnc 0.9.10 or later. Since this does not use Listen mode it should be less error prone and less confusing and more compatible with other features. Be sure to use all of the x11vnc options in the above command line. To enable VeNCrypt, replace '-sslonly' with '-vencrypt force'. If you do not indicate them explicitly to SSVNC, SSVNC may have to probe multiple times for VeNCrypt and/or ANONDH. So you may need '-loop300,4' on the x11vnc cmdline so it will reconnect to the UltraVNC repeater 3 times. Note that for UNENCRYPTED (i.e. direct) SSVNC connections (see vnc:// in Tip 5) using the UltraVNC Repeater mode II there is no need to use a reverse "Listening connection" and so you might as well use a forward connection. For Listening connections, on Windows after the VNC connection you MUST manually terminate the listening VNC Viewer (and connect again if desired.) Do this by going to the System Tray and terminating the Listening VNC Viewer. Subsequent connection attempts using the repeater will fail unless you do this and restart the Listen. On Unix and MacOS X after the VNC connection the UltraVNC repeater proxy script will automatically restart and reconnect to the repeater for another connection. So you do not need to manually restart it. To stop the listening, kill the listening VNC Viewer with Ctrl-C. In the previous sections it was mentioned one can chain up to 3 proxies together by separating them with commas: proxy1,proxy2,proxy3. Except where explicitly noted below this should work for "repeater://..." as the final proxy. E.g. you could use a web proxy to get out of a firewall, and then connect to a remote repeater. The UltraVNC SSL enabled repeater_SSL.exe is discussed below. UltraVNC Single Click: UltraVNC has Single Click (SC) Windows VNC servers that allow naive users to get them running very easily (a EXE download and a few mouse clicks). See http://sc.uvnc.com/ for details on how to create these binaries. Also there is a how-to here: http://www.simply-postcode-lookup.com/SingleClickUltraVNC/SingleClickVNC.htm The SC EXE is a VNC *server* that starts up a Reverse VNC connection to a Listening Viewer (e.g. the viewer address/port/ID is hardwired into the SC EXE). So SC is not really a proxy, but it can be used with UltraVNC repeater proxies and so we describe it here. One important point for SC III binary creation: do NOT include "-id N" in the helpdesk.txt config file. This is because the with SSVNC the Ultra VNC repeater IS NOT USED (see below for how to use it). Use something like for helpdesk.txt: [TITLE] My UltraVNC SC III [HOST] Internet Support XYZ -sslproxy -connect xx.xx.xx.xx:5500 -noregistry (replace xx.xx.xx.xx with IP address or hostname of the SSVNC machine.) The Unix SSVNC vncviewer supports the both the unencrypted "SC I" mode and the SSL encrypted "SC III" mode. For both cases SSVNC must be run in Listening mode (Options -> Reverse VNC Connection) For SC I, enable Reverse VNC Connection and put Vnc://0 (see Tip 5 below) in the VNC Host:Display to disable encryption (use a different number if you are not using the default listening port 5500). Then click on the "Listen" button and finally have the user run your Single Click I EXE. BTW, we used this for a SC I helpdesk.txt: [TITLE] My UltraVNC SC I [HOST] Internet Support XYZ -connect xx.xx.xx.xx:5500 -noregistry For SC III (SSL), enable Reverse VNC Connection and then UNSET "Verify All Certs" (this is required). Let the VNC Host:Display be ":0" (use a different number if you are not using the default listening port 5500). Then click on the "Listen" button and finally have the user run your Single Click III EXE. Note that in Listening SSL mode you MUST supply a MyCert or use the "listen.pem" one you are prompted by SSVNC to create. UltraVNC repeater_SSL.exe proxy: For repeater_SSL.exe SSL usage, with Single Click III or otherwise (available at http://www.uvnc.com/pchelpware/SCIII/index.html) it helps to realize that the ENTIRE connection is SSL encrypted, even the proxy host:port/ID:NNNN negotiation, and so a different approach needs to be taken from that described above in 'UltraVNC Proxies/Gateways'. In this case do something like this: VNC Host:Display: :0 Proxy/Gateway: sslrepeater://myuvncrep.west:443+ID:2345 The sslrepeater:// part indicates the entire ID:XYZ negotiation must occur inside the SSL tunnel. Listening mode is not required in this case: a forward VNC connection works fine (and is recommended). As before, the ":0" is simply a placeholder and is not used. Note that the UltraVNC repeater_SSL.exe listens on port 443 (HTTPS), (it is not clear that it can be modified to use another port.) Non-ID connections sslrepeater://myuvncrep.west:443+host:disp also work, but the 2nd leg repeater <-> host:disp must be unencrypted. The first leg SSVNC <-> repeater is, however, SSL encrypted. sslrepeater:// only works on Unix or MacOSX using the provided SSVNC vncviewer. The modified viewer is needed; stock VNC viewers will not work. Also, proxy chaining (bouncing off of more than one proxy) currently does not work for repeater_SSL.exe. VeNCrypt is treated as a proxy: SSVNC supports the VeNCrypt VNC security type. You will find out more about this security type in the other parts of the Help documentation. In short, it does a bit of plain-text VNC protocol negotiation before switching to SSL/TLS encryption and authentication. SSVNC implements its VeNCrypt support as final proxy in a chain of proxies. You don't need to know this or specify anything, but it is good to know since it uses up one of the 3 proxies you are allowed to chain together. If you watch the command output you will see the vencrypt:// proxy item. You can specify that a VNC server uses VeNCrypt (Options -> Advanced) or you can let SSVNC try to autodetect VeNCrypt. IPv6 can be treated as a proxy for UN-ENCRYPTED connections: Read Tip 20 about SSVNC's IPv6 (128 bit IP addresses) support. In short, because stunnel and ssh support IPv6 hostnames and addresses, SSVNC does too without you needing to do anything. However, in some rare usage modes you will need to specify the IPv6 server destination in the Proxy/Gateway entry box. The only case this appears to be needed is when making an un-encrypted connection to an IPv6 VNC server. In this case neither stunnel nor ssh are used and you need to specify something like this: VNC Host:Display: localhost:0 Proxy/Gateway: ipv6://2001:4860:b009::68:5900 and then select 'None' as the encryption type. Note that the above 'localhost:0' setting can be anything; it is basically ignored. Note that on Unix, MacOSX, and Windows un-encrypted ipv6 connections are AUTODETECTED and so you likely NEVER need to supply ipv6:// Only try it if you encounter problems. Also note that the ipv6:// proxy type does not work on Windows, so only the autodetection is available there. Note that if there is some other proxy, e.g. SOCKS or HTTP and that proxy server is an IPv6 host (or will connect you to one) then any sort of connection through that proxy will work OK: un-encrypted as well as SSL or SSH connections, etc. Unencrypted connection is the only special case where you may need to specify an ipv6:// proxy. If you find another use let us know. See Tip 20 for more info. } set help_tips { Tips and Tricks: Table of Contents: 1) Connect to Non-Standard SSH port. 2) Reverse VNC connections (Listening) 3) Global options in ~/.ssvncrc 4) Fonts 5) vnc://host for un-encrypted connection 6) Home directory for memory stick usage, etc. 7) vncs:// vncssl:// vnc+ssl:// vnc+ssh:// URL-like prefixes 8) sshvnc / -ssh SSH only GUI 9) tsvnc / -ts Terminal services only GUI (SSH+x11vnc) 10) 2nd GUI window on Unix/MacOSX 11) Ctrl-L or Button3 to Load profile 12) SHELL command or Ctrl-S for SSH terminal w/o VNC 13) KNOCK command for port-knock sequence 14) Unix/MacOSX general SSL redirector (not just VNC) 15) Environment variables 16) Bigger "Open File" dialog window 17) Unix/MacOSX extra debugging output 18) Dynamic VNC Server Port determination with SSH 19) No -t ssh cmdline option for older sshd 20) IPv6 support. 1) To connect in SSH-Mode to a server running SSH on a non-standard port (22 is the standard port) you need to use the Proxy/Gateway setting. The following is from the Proxies Help panel: NON-STANDARD SSH PORT: To use a non-standard ssh port (i.e. a port other than 22) you need to use the Proxy/Gateways as well. E.g. something like this for port 2222: VNC Host:Display: localhost:0 Proxy/Gateway: joe@far-away.east:2222 The username@ is not needed if it is the same as on the client. This will also work going to a different internal machine, e.g. "joes-pc:0" instead of "localhost:0", as in the first example. 2) Reverse VNC connections (Listening) are possible as well. In this case the VNC Server initiates the connection to your waiting (i.e. listening) SSVNC viewer. Go to Options and select "Reverse VNC connection". In the 'VNC Host:Display' entry box put in the number (e.g. "0" or ":0", or ":1", etc) that corresponds to the Listening display (0 -> port 5500, 1 -> port 5501, etc.) you want to use. Then clicking on 'Listen' puts your SSVNC viewer in a "listening" state on that port number, waiting for a connection from the VNC Server. On Windows or using a 3rd party VNC Viewer multiple, simultaneous reverse connections are always enabled. On Unix/MacOSX with the provided ssvncviewer they are disabled by default. To enable them: Options -> Advanced -> Unix ssvncviewer -> Multiple LISTEN Connections Specify a specific interface, e.g. 192.168.1.1:0 to have stunnel only listen on that interface. IPv6 works too, e.g. :::0 or ::1:0 This also works for UN-encrypted reverse connections as well ('None'). See the Options Help for more info. 3) You can put global options in your ~/.ssvncrc file (ssvnc_rc on Windows). Currently they are: Put "mode=tsvnc" or "mode=sshvnc" in the ~/.ssvncrc file to have the application start up in the given mode. desktop_type=wmaker (e.g.) to switch the default Desktop Type. desktop_size=1280x1024 (e.g.) to switch the default Desktop Size. desktop_depth=24 (e.g.) to switch the default Desktop Color Depth xserver_type=Xdummy (e.g.) to switch the default X Server Type. (The above 4 settings apply only to the Terminal Services Mode.) noenc=1 (same as the -noenc option for a 'No Encryption' option) noenc=0 (do not show the 'No Encryption' option) killstunnel=1 (same as -killstunnel), on Windows automatically kills the STUNNEL process when the viewer exits. Disable via killstunnel=0 and -nokillstunnel. ipv6=0 act as though IPv6 was not detected. ipv6=1 act as though IPv6 was detected. cotvnc=1 have the default vncviewer on Mac OS X be the Chicken of the VNC. By default the included ssvnc X11 vncviewer is used (requires Mac OS X X11 server to be running.) mycert=file (same as -mycert file option). Set your default MyCert to "file". If file does not exist ~/.vnc/certs/file is used. cacert=file (same as -cacert file option). Set your default ServerCert to "file". If file does not exist ~/.vnc/certs/file is used. If file is "CA" then ~/.vnc/certs/CA/cacert.pem is used. crl=file (same as -crl file option). Set your default CRL File to "file". If file does not exist ~/.vnc/certs/file is used. Prefix any of these cert/key files with "FORCE:" to make them immutable, e.g. "cacert=FORCE:CA". You can set any environment variable in ~/.ssvncrc by using a line like env=VAR=value, for example: env=SSVNC_FINISH_SLEEP=2 To change the fonts (see Tip 4 below for examples): font_default=tk-font-name (sets the font for menus and buttons) font_fixed=tk-font-name (sets the font for help text) 4) Fonts: To change the tk fonts, set these environment variables before starting up ssvnc: SSVNC_FONT_DEFAULT and SSVNC_FONT_FIXED. For example: % env SSVNC_FONT_DEFAULT='helvetica -20 bold' ssvnc % env SSVNC_FONT_FIXED='courier -14' ssvnc or set both of them at once. You can also set 'font_default' and 'font_fixed' in your ~/.ssvncrc. E.g.: font_default=helvetica -16 bold font_fixed=courier -12 5) If you want to make a Direct VNC connection, WITH *NO* SSL OR SSH ENCRYPTION or authentication, use the "vnc://" prefix in the VNC Host:Display entry box, e.g. "vnc://far-away.east:0" This also works for reverse connections, e.g. vnc://0 Use Vnc:// (i.e. capital 'V') to avoid being prompted if you are sure you want no encryption. For example, "Vnc://far-away.east:0" Shift+Ctrl-E in the entry box is a short-cut to add or remove the prefix "Vnc://" from the host:disp string. You can also run ssvnc with the '-noenc' cmdline option (now the default) to have a check option 'None' that lets you turn off Encryption (and profiles will store this setting). Pressing Ctrl-E on the main panel is a short-cut to toggle between the -noenc 'No Encryption' mode and normal mode. The option "Show 'No Encryption' Option" under Options also toggles it. The '-enc' option disables the button (and so makes it less obvious to naive users how to disable encryption.) Note as of SSVNC 1.0.25 the '-noenc' mode is now the default. I.e. the 'No Encryption' option ('None') is shown by default. When you select 'None' you do not need to supply the "vnc://" prefix. To disable the button supply the '-enc' cmdline option. Setting SSVNC_DISABLE_ENCRYPTION_BUTTON=1 in your environment is the same as -noenc. You can also put noenc=1 in your ~/.ssvncrc file. Setting SSVNC_DISABLE_ENCRYPTION_BUTTON=0 in your environment is the same as -enc. You can also put noenc=0 in your ~/.ssvncrc file. Please be cautious/thoughtful when you make a VNC connection with encryption disabled. You may send sensitive information (e.g. a password) over the network that can be sniffed. It is also possible (although difficult) for someone to hijack an existing unencrypted VNC session. Often SSVNC is used to connect to x11vnc where the Unix username and password is sent over the channel. It would be a very bad idea to let that data be sent over an unencrypted connection! In general, it is not wise to have a plaintext VNC connection. Note that even the VNC Password challenge-response method (the password is not sent in plaintext) leaves your VNC password susceptible to a dictionary attack unless encryption is used to hide it. So (well, before we made the button visible by default!) we forced you to learn about and supply the "vnc://" or "Vnc://" prefix to the host:port or use -noenc or the "Show 'No Encryption' Option" to disable encryption. This is a small hurdle, but maybe someone will think twice. It is a shame that VNC has been around for over 10 years and still does not have built-in strong encryption. Note the Vnc:// or vnc:// prefix will be stored in any profile that you save so you do not have to enter it every time. Set the env var SSVNC_NO_ENC_WARN=1 to skip the warning prompts the same as the capitalized Vnc:// does. 6) Mobile USB memory stick / flash drive usage: You can unpack ssvnc to a flash drive for impromptu usage (e.g. from a friends computer). If you create a directory "Home" in the toplevel ssvnc directory, then that will be the default location for your VNC profiles and certs. So they follow the drive this way. If you run like this: "ssvnc ." or "ssvnc.exe ." the "Home" directory will be created for you. WARNING: if you use ssvnc from an "Internet Cafe", i.e. an untrusted computer, an unscrupulous person may be capturing keystrokes, etc.! You can also set the SSVNC_HOME env. var. to point to any directory you want. It can be set after starting ssvnc by putting HOME=/path/to/dir in the Host:Display box and clicking "Connect". For a Windows BAT file to get the "Home" directory correct something like this might be needed: cd \ssvnc\Windows start \ssvnc\Windows\ssvnc.exe 7) In the VNC Host:Display entry you can also use these "URL-like" prefixes: vncs://host:0, vncssl://host:0, vnc+ssl://host:0 for SSL and vncssh://host:0, vnc+ssh://host:0 for SSH There is no need to toggle the SSL/SSH setting. These also work from the command line, e.g.: ssvnc vnc+ssh://mymachine:10 8) If you want this application to be SSH only, then supply the command line option "-ssh" or set the env. var SSVNC_SSH_ONLY=1. Then no GUI elements specific to SSL will appear (the documentation wills still refer to the SSL mode, however). To convert a running app to ssh-only select "Mode: SSH-Only" in Options. The wrapper scripts "sshvnc" and "sshvnc.bat" will start it up automatically this way. Or in your ~/.ssvncrc (or ~/ssvnc_rc on Windows) put "mode=sshvnc" to have the tool always start up in that mode. 9) For an even simpler "Terminal Services" mode use "tsvnc" or "tsvnc.bat" (or "-ts" option). This mode automatically launches x11vnc on the remote side to find or create your Desktop session (usually the Xvfb X server). So x11vnc must be available on the remote server machines under "Terminal Services" mode. From a full ssvnc you can press Ctrl-h to go into ssh-only mode and Ctrl-t to toggle between "tsvnc" and "ssvnc" modes. The Options Mode menu also let you switch. Or in your ~/.ssvncrc (or ~/ssvnc_rc on Windows) put "mode=tsvnc" to have the tool always start up in that mode. 10) On Unix to get a 2nd GUI (e.g. for a 2nd connection) press Ctrl-N on the GUI. If only the xterm window is visible you can press Ctrl-N or try Ctrl-LeftButton -> New SSVNC_GUI. On Windows you will have to manually Start a new one: Start -> Run ..., etc. 11) Pressing the "Load" button or pressing Ctrl-L or Clicking the Right mouse button on the main GUI will invoke the Load dialog. Pressing Ctrl-O on the main GUI will bring up the Options Panel. Pressing Ctrl-A on the main GUI will bring up the Advanced Options. 12) If you use "SHELL" for the "Remote SSH Command" (or in the display line: "user@hostname cmd=SHELL") then you get an SSH shell only: no VNC viewer will be launched. On Windows "PUTTY" will try to use putty.exe (better terminal emulation than plink.exe). A ShortCut for this is Ctrl-S with user@hostname in the entry box. 13) If you use "KNOCK" for the "Remote SSH Command" (or in the display line "user@hostname cmd=KNOCK") then only the port-knocking is done. A ShortCut for this is Ctrl-P with hostname the entry box. If it is KNOCKF, i.e. an extra "F", then the port-knocking "FINISH" sequence is sent, if any. A ShortCut for this Shift-Ctrl-P as long as hostname is present. 14) On Unix to have SSVNC act as a general STUNNEL redirector (i.e. no VNC), put the desired host:port in VNC Host:Display (use a negative port value if it is to be less than 200), then go to Options -> Advanced -> Change VNC Viewer. Change the "viewer" command to be "xmessage OK" or "xmessage " (or sleep) where port is the desired local listening port. Then click Connect. If you didn't set the local port look for it in the terminal output. On Windows set 'viewer' to "NOTEPAD" or similar; you can't control the port though. It is usually 5930, 5931, ... Watch the messages or look at the stunnel log. 15) Tricks with environment variables: You can change the X DISPLAY variable by typing DISPLAY=... into VNC Host:Display and hitting Return or clicking Connect. Same for HOME=. On Mac, you can set DYLD_LIBRARY_PATH=... too. It should propagate down the viewer. Setting SLEEP=n increases the amount of time waited before starting the viewer. The env. var. SSVNC_EXTRA_SLEEP also does this (and also Sleep: Option setting) Setting FINISH=n sets the amount of time slept before the Terminal window exits on Unix and MacOS X. (same as SSVNC_FINISH_SLEEP env. var.) Full list of parameters HOME/SSVNC_HOME, DISPLAY/SSVNC_DISPLAY DYLD_LIBRARY_PATH/SSVNC_DYLD_LIBRARY_PATH, SLEEP/SSVNC_EXTRA_SLEEP FINISH/SSVNC_FINISH_SLEEP, DEBUG_NETSTAT, REPEATER_FORCE, SSH_ONLY, TS_ONLY, NO_DELETE, BAT_SLEEP, IPV6/SSVNC_IPV6=0 or 1. See below for more info. (the ones joined by "/" are equivalent names, and the latter can be set as an env. var. as well.) After you set the parameter, clear out the 'VNC Host:Display' entry and replace it with the actual host and display number. To replace the xterm terminal where most of the external commands are run set SSVNC_XTERM_REPLACEMENT to a command that will run a command in a terminal. I.e.: "$SSVNC_XTERM_REPLACEMENT cmd" will run cmd. If present, %GEOMETRY is expanded to a desired +X+Y geometry. If present, %TITLE is expanded to a desired title. Examples: SSVNC_XTERM_REPLACEMENT='gnome-terminal -e' SSVNC_XTERM_REPLACEMENT='gnome-terminal -t "%TITLE" -e' SSVNC_XTERM_REPLACEMENT='konsole -e' More info: EXTRA_SLEEP: seconds of extra sleep in scripts; FINISH_SLEEP: final extra sleep at end; DEBUG_NETSTAT put up a window showing what netstat reports; NO_DELETE: do not delete tmp bat files on Windows (for debugging); BAT_SLEEP: sleep this many seconds at the end of each Windows bat file (for debugging.) You can also set any environment variable by entering in something like ENV=VAR=VAL e.g. ENV=SSH_AUTH_SOCK=/tmp/ssh-BF2297/agent.2297 Use an empty VAL to unset the variable. There are also a HUGE number of env. vars. that apply to the Unix and MacOS X wrapper script 'ss_vncviewer' and/or the ssvncviewer binary. See Options -> Advanced -> Unix ssvncviewer -> Help for all of them. 16) On Unix you can make the "Open File" and "Save File" dialogs bigger by setting the env. var. SSVNC_BIGGER_DIALOG=1 or supplying the -bigger option. If you set it to a Width x Height, e.g. SSVNC_BIGGER_DIALOG=500x200, that size will be used. 17) On Unix / MacOSX to enable debug output you can set these env. vars to 1: SSVNC_STUNNEL_DEBUG, SSVNC_VENCRYPT_DEBUG, and SS_DEBUG (very verbose) 18) Dynamic VNC Server Port determination and redirection: If you are running SSVNC on Unix and are using SSH to start the remote VNC server and the VNC server prints out the line "PORT=NNNN" to indicate which dynamic port it is using (x11vnc does this), then if you prefix the SSH command with "PORT=" SSVNC will watch for the PORT=NNNN line and uses ssh's built in SOCKS proxy (ssh -D ...) to connect to the dynamic VNC server port through the SSH tunnel. For example: VNC Host:Display user@somehost.com Remote SSH Command: PORT= x11vnc -find -nopw or "PORT= x11vnc -display :0 -localhost", etc. Or use "P= ..." There is also code to detect the display of the regular Unix vncserver(1). It extracts the display (and hence port) from the lines "New 'X' desktop is hostname:4" and also "VNC server is already running as :4". So you can use something like: PORT= vncserver; sleep 15 or: PORT= vncserver :4; sleep 15 the latter is preferred because when you reconnect with it will find the already running one. The former one will keep creating new X sessions if called repeatedly. On Windows if PORT= is supplied SOCKS proxying is not used, but rather a high, random value of the VNC port is chosen (e.g. 8453) and assumed to be free, and is passed to x11vnc's -rfbport option. This only works with x11vnc (not vncserver). 19) On Unix if you are going to an older SSH server (e.g. Solaris 10), you will probably need to set the env. var. SS_VNCVIEWER_NO_T=1 to disable the ssh "-t" option being used (that can prevent the command from being run). 20) SSVNC is basically a wrapper for the stunnel and ssh programs, and because those two programs have good IPv6 support SSVNC will for most usage modes support it as well. IPv6 is 128 bit internet addresses (as opposed to IPv4 with its 32 bit xxx.yyy.zzz.nnn IPs. So for basic SSL and SSH connections if you type in an IPv6 IP address, e.g. '2001:4860:b009::68', or a hostname with only an IPv6 lookup, e.g. ipv6.l.google.com, the connection will work because stunnel and ssh handle these properly. Note that you often need to supply a display number or port after the address so put it, e.g. ':0' at the end: 2001:4860:b009::68:0 You can also use the standard notation [2001:4860:b009::68]:0 that is more clear. You MUST specify the display if you use the IPv6 address notation (but :0 is still the default for a non-numeric hostname string.) IPv4 addresses encoded in IPv6 notation also work, e.g. ::ffff:192.168.1.100 should work for the most part. SSVNC on Unix and MacOSX also has its own Proxy helper tool (pproxy) This script has been modified to handle IPv6 hostnames and addresses as long as the IO::Socket::INET6 Perl module is available. On Windows the relay6.exe tool is used. So for the most part IPv6 should work without you having to do anything special. However, for rare usage, the proxy helper tool can also treat and IPv6 address as a special sort of 'proxy'. So in the entry Proxy/Gateway you can include ipv6://host:port and the IPv6 host will simply be connected to and the data transferred. In this usage mode, set the VNC Host:Display to anything, e.g. 'localhost:0'; it is ignored if the ipv6:// endpoint is specified as a proxy. Need for ipv6:// usage proxy should be rare. Note that for link local (not global) IPv6 addresses you may need to include the network interface at the end of the address, e.g. fe80::a00:20ff:fefd:53d4%eth0 Note that one can use a 3rd party VNC Viewer with SSVNC (see Options -> Advanced -> Change VNC Viewer.) IPv6 will work for them as well even if they do not support IPv6. IPv6 support on Unix, MacOSX, and Windows is essentially complete for all types of connections (including proxied, unencrypted and reverse connections.) Let us know if you find a scenario that does not work (see the known exception for putty/plink below.) You can set ipv6=0 in your ssvncrc, then no special relaying for IPv6 will be done (do this if there are problems or slowness in trying to relay ipv6 and you know you will not connect to any such hosts.) Set ipv6=1 to force the special processing even if IPv6 was not autodetected. To change this dynamically, you also enter IPV6=... in the VNC Host:Display entry box and press Enter. Also on Unix or MacOSX you can set the env. var. SSVNC_IPV6=0 to disable the wrapper script from checking if hosts have ipv6 addresses (this is the same as setting ipv6=0 in ssvncrc or by the setting ipv6 in the Entry box.) On Windows plink.exe (SSH client) currently doesn't work for IPv6 address strings (e.g. 2001:4860:b009::68) but it does work for hostname strings that resolve to IPv6 addresses. Note that one can make a home-brew SOCKS5 ipv4-to-ipv6 gateway proxy using ssh like this: ssh -D '*:1080' localhost "printf 'Press Enter to Exit: '; read x" then specify a proxy like socks5://hostname:1080 where hostname is the machine running the above ssh command. Add '-v' to the ssh cmdline for verbose output.

So, when you have all of the modifier keys ('escape keys') pressed down, then subsequent keystrokes are interpreted as local special actions instead of being sent to the remote VNC server. This enables quick parameter changing and also panning of the viewport. E.g. the keystroke 'r' is mapped to refresh the screen. Enter 'default' in the entry box to enable this feature and to use the default modifier list (Alt_L,Super_L on unix and Control_L,Meta_L on macosx) or set it to a list of modifier keys, e.g. Alt_L,Control_L. Note that _L means left side of keyboard and _R means right side. Alt_L is the 'Alt' key on the left side of the keyboard, and Super_L is usually the 'WindowsFlaggie(TM)' on the left side of the keyboard, so when both of those are pressed, the escape keys mapping take effect. Here is info from the ssvncviewer(1) manual page: -escape str This sets the 'Escape Keys' modifier sequence and enables escape keys mode. When the modifier keys escape sequence is held down, the next keystroke is interpreted locally to perform a special action instead of being sent to the remote VNC server. Use '-escape default' for the default modifier sequence. (Unix: Alt_L,Super_L and MacOSX: Control_L,Meta_L) Here are the 'Escape Keys: Help+Set' instructions from the Popup Menu: Escape Keys: Enter a comma separated list of modifier keys to be the 'escape sequence'. When these keys are held down, the next keystroke is interpreted locally to invoke a special action instead of being sent to the remote VNC server. In other words, a set of 'Hot Keys'. To enable or disable this, click on 'Escape Keys: Toggle' in the Popup. Here is the list of hot-key mappings to special actions: r: refresh desktop b: toggle bell c: toggle full-color f: file transfer x: x11cursor z: toggle Tight/ZRLE l: full screen g: graball e: escape keys dialog s: scale dialog +: scale up (=) -: scale down (_) t: text chat a: alphablend cursor V: toggle viewonly Q: quit viewer 1 2 3 4 5 6: UltraVNC scale 1/n Arrow keys: pan the viewport about 10% for each keypress. PageUp / PageDown: pan the viewport by a screenful vertically. Home / End: pan the viewport by a screenful horizontally. KeyPad Arrow keys: pan the viewport by 1 pixel for each keypress. Dragging the Mouse with Button1 pressed also pans the viewport. Clicking Mouse Button3 brings up the Popup Menu. The above mappings are *always* active in ViewOnly mode, unless you set the Escape Keys value to 'never'. If the Escape Keys value below is set to 'default' then a default list of of modifier keys is used. For Unix it is: Alt_L,Super_L and for MacOSX it is Control_L,Meta_L. Note: the Super_L key usually has a Windows(TM) Flag on it. Also note the _L and _R mean the key is on the LEFT or RIGHT side of the keyboard. On Unix the default is Alt and Windows keys on Left side of keyboard. On MacOSX the default is Control and Command keys on Left side of keyboard. Example: Press and hold the Alt and Windows keys on the LEFT side of the keyboard and then press 'c' to toggle the full-color state. Or press 't' to toggle the ultravnc Text Chat window, etc. To use something besides the default, supply a comma separated list (or a single one) from: Shift_L Shift_R Control_L Control_R Alt_L Alt_R Meta_L Meta_R Super_L Super_R Hyper_L Hyper_R or Mode_switch. } .ekh.f.t insert end $msg jiggle_text .ekh.f.t } # Or Alternatively one can supply both hosts separated by # spaces (with the proxy second) in the VNC Host:Display box: # # VNC Host-Display: far-away.east:0 theproxy.net:8080 # # This looks a little strange, but it actually how SSVNC stores the # host info internally. # You can also specify the remote SSH command by putting a string like # # cmd=x11vnc -nopw -display :0 -rfbport 5900 -localhost # # (use any command you wish to run) at the END of the VNC Host:Display # entry.

Otherwise, only passive network sniffing attacks are prevented. There are hacker tools like dsniff/webmitm and cain that implement SSL Man-In-The-Middle attacks. They rely on the client user not bothering to check the cert. Some people may be confused by the above because they are familiar with their Web Browser using SSL (i.e. https://... websites) and those sites are authenticated securely without the user's need to verify anything manually. The reason why this happens automatically is because 1) their web browser comes with a bundle of Certificate Authority certificates and 2) the https sites have paid money to the Certificate Authorities to have their website certificate signed by them. When using SSL in VNC we normally do not do something this sophisticated, and so we have to verify the certificates manually. However, it is possible to use Certificate Authorities with SSVNC; that method is described below. The SSL Certificate files described below may have been created externally (e.g. by x11vnc or openssl): you can import them via "Import Certificate". OR you can click on "Create Certificate ..." to use THIS program to generate a Certificate + Private Key pair for you (in this case you will need to distribute one of the generated files to the VNC Server). Then you associate the Saved cert with the VNC server, see the panel entry box description below. Then click Connect. You will usually want to Save this association in a VNC Server profile for the next time you connect. Expiration: SSL Certificates will Expire after a certain period (usually 1-2 years; if you create a cert with this tool you can set it to any length you want). So if for a particular Cert you find you can no longer connect, check the STUNNEL log output to see if the cert has expired. Then create and distribute a new one. Fetch Cert: You can also retrieve and view the VNC Server's Cert via the "Fetch Cert" button on the main panel. After you check that it is the correct Cert (e.g. by comparing MD5 hash or other info), you can save it. The file it was saved as will be set as the "ServerCert" to verify against for the next connection. To make this verification check permanent, you will need to save the profile via 'Save'. NOTE: See the CA section below for how "Fetch Cert/Verify All Certs" WILL NOT WORK when a Certificate Authority (CA) is used (i.e. you need to save the CA's cert instead.) It will work if the certificate is Self-Signed. Verify All Certs: If "Verify All Certs" is checked on the main panel, you are always forced to check unrecognized server certs, and so the first time you connect to a new server you may need to follow a few dialogs to inspect and save the server certificate. Under "Verify All Certs", new certificates are saved in the 'Accepted Certs' directory. When the checkbox is set all host profiles with "CertsDir" set to "ACCEPTED_CERTS" (and an empty "ServerCert" setting) will be checked against the pool of accepted certificates in the 'Accepted Certs' directory. Note that we have "Verify All Certs" on by default so that users who do not understand the SSL Man-In-The-Middle problem will not be left completely vulnerable to it. Everyone still must make the effort to verify new certificates by an external method to be completely safe. To have "Verify All Certs" toggled off at startup, use "ssvnc -nv" or set SSVNC_NO_VERIFY_ALL=1 before starting. If you do not even want to see the button, use "ssvnc -nvb" or SSVNC_NO_VERIFY_ALL_BUTTON=1. Note: "Fetch Cert" and "Verify All Certs" are currently not implemented in "SSH + SSL" mode. In this case to have server authentication "ServerCert" must be set explicitly to a file (or "CertsDir" to a directory). Also note that "Fetch Cert" only works in a limited fashion in "Listen" mode (it is the VNC Server that initiates the connection), and so you may need to be set via "ServerCert" as well. NOTE: See the CA section below for how "Fetch Cert/Verify All Certs" WILL NOT WORK when a Certificate Authority (CA) is used (i.e. you need to save the CA's cert instead.) The "Fetch Cert" saving method will work if the certificate is Self-Signed. CA: One can make SSL VNC server authentication more "automatic" as it is in Web Browsers going to HTTPS sites, by using a Certificate Authority (CA) cert (e.g. a professional one like Verisign or Thawte, or one your company or organization creates) for the "ServerCert". This is described in detail here: http://www.karlrunge.com/x11vnc/ssl.html CA's are not often used, but if the number of VNC Servers scales up it can be very convenient because the viewers (i.e. SSVNC) only need the CA cert, not all of the Server certs. IMPORTANT NOTE: if a VNC Server is using a CA signed certificate instead of its own Self-Signed one, then "Fetch Cert", etc. saving mechanism WILL NOT WORK. You must obtain the CA certificate and explicitly set it as the ServerCert or import it to 'Accepted Certs'. Now what goes into the panel's entry boxes is described. Your Certificate + Key (MyCert): You can specify YOUR own SSL certificate (PEM) file in "MyCert" in which case it is used to authenticate YOU (the viewer) to the remote VNC Server. If this fails the remote VNC Server will drop the connection. So the Server could use this method to authenticate Viewers instead of the more common practice of using a VNC password or x11vnc's -unixpw mode. Server Certificates (ServerCert/CertsDir): Server certs can be specified in one of two ways: - A single certificate (PEM) file for a single server or a single Certificate Authority (CA) - A directory of certificate (PEM) files stored in the special OpenSSL hash fashion. The former is set via "ServerCert" in this gui. The latter is set via "CertsDir" in this gui. The former corresponds to the "CAfile" STUNNEL parameter. The latter corresponds to the "CApath" STUNNEL parameter. See stunnel(8) or stunnel.mirt.net for more information. If the remote VNC Server fails to authenticate itself with respect to the specified certificate(s), then the VNC Viewer (your side) will drop the connection. Select which file or directory by clicking on the appropriate "Browse..." button. Once selected, if you click Info or the Right Mouse button on "Browse..." then information about the certificate will be displayed. If, as is the default, "CertsDir" is set to the token "ACCEPTED_CERTS" (and "ServerCert" is unset) then the certificates accumulated in the special 'Accepted Certs' directory will be used. "ACCEPTED_CERTS" is the default for every server ("Verify All Certs"). Note that if you ever need to clean this directory, each cert is saved in two files, for example: hostname-0=bf-d0-d6-9c-68-5a-fe-24-c6-60-ba-b4-14-e6-66-14.crt and 9eb7c8be.0 This is because of the way OpenSSL must use hash-based filenames in Cert dirs. The file will have a "full filename:" line indicating the fingerprint and hostname associated with it. Be sure to remove both files. The Delete Certs dialog should automatically find the matching one for you and prompt you to remove it as well. Certificate Revocation List (CRL File): For large scale deployments, usually involving a CA Cert, it is worthwhile to be able to revoke individual certs (so that a new CA cert does not need to be created and new keys distributed). Set CRL File to the path to the file containing the revoked certificates (or a directory containing OpenSSL style hash-based filenames.) See the x11vnc -sslCRL documentation for how to create CRL's. In short, the commands 'openssl ca -revoke ...' and 'openssl ca -gencrl ...' are the ones to look for; See the ca(1) manpage. Create Certificate: A simple dialog to create a Self-Signed Certificate. See the x11vnc -sslGenCA, -sslGenCert options for creating a CA Cert and signing with it. Import Certificate: You can paste in a Certificate or read one in from a file to add to your list of Server Certificates. If (also) saved in the 'Accepted Certs' directory, it will be automatically used to verify any Server when in 'Verify All Certs' Mode. Deleting Certificates: To delete a Certificate+private_key pair click on "Delete Certificate" and select one in the menu. You will be prompted to remove it, and also any corresponding .pem or .crt file. For "ACCEPTED_CERTS" it will find the matching "HASH" file and prompt you to remove that too. Default Certs and Keys: Use the "-mycert file" option (same as "-cert file") to set a default MyCert. The user will then have to manually clear the field to not use a certificate. This is the same as "mycert=file" (also "cert=file") in the ~/.ssvncrc file. If "file" does not exist, then ~/.vnc/certs is prepended to it. Use the "-cacert file" option (same as "-ca file") to set a default ServerCert. The user will then have to manually clear the field to not set a server cert. This is the same as "cacert=file" (also "ca=file") in the ~/.ssvncrc file. If "file" does not exist, then ~/.vnc/certs is prepended to it. Use "-cacert CA" to set it to ~/.vnc/certs/CA/cacert.pem Use the "-crl file" option to set a default CRL File. The user will then have to manually clear the field to not use a CRL. This is the same as "crl=file" in the ~/.ssvncrc file. If "file" does not exist, then ~/.vnc/certs is prepended to it. A sys-admin might set up an SSVNC deployment for user's workstations or laptops using one or more of -cacert (authenticate VNC server to the user) or -mycert (authenticate user to VNC server) or -crl (supply a list of revoked certificates). Prefix either one with "FORCE:" to make the setting unchangable. Notes: If "Use SSH" has been selected then SSL certs are disabled. See the x11vnc and STUNNEL documentation for how to create and use PEM certificate files: http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-tunnel-ext http://www.karlrunge.com/x11vnc/ssl.html http://stunnel.mirt.net A common way to create and use a VNC Server certificate is: x11vnc -ssl SAVE ... and then copy the Server certificate to the local (viewer-side) machine. x11vnc prints out to the screen the Server certificate it generates (stored in ~/.vnc/certs/server.crt). You can set "ServerCert" to it directly or use the "Import Certificate" action to save it to a file. Or use the "Fetch Cert" method to retrieve it (be sure to verify the MD5 fingerprint, etc). x11vnc also has command line utilities to create server, client, and CA (Certificate Authority) certificates and sign with it.

Deselecting a checkbox will disable the feature (but settings from the Dialog are remembered). Click on it again to re-enable. Desktop Type: The default type of remote Desktop type is the "kde" (The K Desktop Environment) You can choose a different type: gnome, failsafe, twm, etc. This setting will ONLY be used if the desktop needs to be created. If an existing session of yours is found it will be used instead (log out of that session if you want to create a new Desktop type or see the Multiple Sessions option under Advanced). Desktop Size: The default size of remote Desktop type is the "1280x1024" with a Color depth of 16 bits per pixel (BPP). Choose one of the standard WxH values or enter a custom one (TBD). This setting will ONLY be used if the desktop needs to be created. If an existing session of yours is found it will be used instead (log out of that session if you want to create a new Desktop size or see the Multiple Sessions option under Advanced). Some X servers, Xdummy or a real X server, will allow dynamic screen size changing after the session has started via a GUI configuration tool (or xrandr(1) from the command line). X Server Type: The default type of remote X session is the "Xvfb" (X virtual frame buffer) X server. It is available on most systems. To choose a different type, select "Xdummy", "Xvnc", "Xvnc.redirect". Xdummy is part of the x11vnc project and is a virtual X server with some nice features, but it Linux only and requires root permission to run. One user put 'ALL ALL = NOPASSWD: /usr/local/bin/Xdummy*' in his sudo(1) configuration (via visudo). For Xvnc that server is started up, and x11vnc polls it in its normal way. Use Xvnc.redirect if you want x11vnc to find and/or create the Xvnc session, but after that merely transfer packets back and forth between VNC viewer and Xvnc (I.e. x11vnc does no polling or VNC protocol). Enable Printing: This sets up a SSH port redirection for you from your remote session to your local print server. The CUPS mechanism is used. The local print server can also be SMB/Windows. Enable Sound: Not completely implemented yet. A partially working ESD method is provided. It may change over to http://nas.sourceforge.net in the future. As with printing, it uses a SSH port redirection to a server running locally. File Transfer: x11vnc supports both the UltraVNC and TightVNC file transfer extensions. On Windows both viewers support their file transfer protocol. On Unix only the SSVNC VNC Viewer has filexfer support; it supports the UltraVNC flavor via a Java helper program. Choose the one you want based on VNC viewer you will use. The defaults for the SSVNC viewer package are TightVNC on Windows and UltraVNC on Unix. View Only: Start the VNC Viewer in View-Only mode (it may be switched to full access later in the session). Change VNC Viewer: If you do not like the VNC Viewer bundled in the package, you can indicate another one here. X11 viewer MacOSX: On MacOSX try to use the bundled X11 vncviewer instead of the Chicken of the VNC viewer; the Xquartz X server must be installed (it is by default on 10.5.x) and the DISPLAY variable must be set (see Tip 15 of SSVNC Help to do this manually.) Advanced Options: VNC Shared: Normal use of this program, 'tsvnc', *ALREADY* allows simultaneous shared access of the remote desktop: You simply log in as many times from as many different locations with 'tsvnc' as you like. Select this option for the traditional VNC server shared mode of operation using a single x11vnc server. SSH access is still required. Multiple Sessions: To enable one user to have more than one Terminal Services Desktop X session on a single machine, this option lets you create Tags for multiple ones (e.g. KDE_BIG, TWM_800x600) X Login Greeter: If you have root (sudo(1)) permission on the remote machine, you can have x11vnc try to connect to X displays that have nobody logged in yet. This is most likely the login greeter running on the Physical console. sudo(1) is used to run x11vnc with FD_XDM=1. An initial ssh running 'sudo id' is performed to try to 'prime' sudo so the 2nd one that starts x11vnc does not need a password. Note that if someone is already logged into the console of the XDM display you will see their X session. Other VNC Server: The x11vnc program running on the remote machine can be instructed to immediately redirect to some other (3rd party, e.g. Xvnc or vnc.so) VNC server. Use unixpw: This enables the x11vnc unixpw mode. A Login: and Password: dialog will be presented in the VNC Viewer for the user to provide any Unix username and password whose session he wants to connect to. This mode is useful if a shared terminal services user (e.g. 'tsuser') is used for the SSH login part (say via the SSH authorized_keys mechanism and all users share the same private SSH key for 'tsuser'). In normal usage the per-user SSH login should be the simplest and sufficient, in which case the unixpw option should NOT be selected. Client 8bit Color: Have the VNC Viewer request low color mode (8 bits per pixel) for slow links. This may be disabled or further tuned (e.g. 64 color mode) in the viewer during the session. Client-Side Caching: x11vnc has an experiment Client-Side caching scheme "-ncache n" that can give nice speedups. But there are some drawbacks because the cache-region is visible and uses much RAM. http://www.karlrunge.com/x11vnc/faq.html#faq-client-caching X11VNC Options: If you are familiar with x11vnc, you can specify any of its features that you would like enabled. SSVNC Mode: Clicking on this button will return you to the full SSVNC Mode. Unix ssvncviewer: Clicking on this button will popup a menu for setting options of the Unix (and Mac OS X) provided SSVNC vncviewer. ~/.ssvncrc file: You can put global options in your ~/.ssvncrc file (ssvnc_rc on Windows). Currently they are: Put "mode=tsvnc" or "mode=sshvnc" in the ~/.ssvncrc file to have the application start up in the given mode. desktop_type=wmaker (e.g.) to switch the default Desktop Type. desktop_size=1280x1024 (e.g.) to switch the default Desktop Size. desktop_depth=24 (e.g.) to switch the default Desktop Color Depth. xserver_type=Xdummy (e.g.) to switch the default X Server Type. (The above 4 settings apply only to the Terminal Services Mode.) noenc=1 (same as the -noenc option for a 'No Encryption' option) noenc=0 (do not show the 'No Encryption' option) font_default=tk-font-name (sets the font for menus and buttons) font_fixed=tk-font-name (sets the font for help text) } .oh.f.t insert end $msg jiggle_text .oh.f.t } proc help_opts {} { toplev .oh scroll_text_dismiss .oh.f center_win .oh wm title .oh "SSL/SSH Viewer Options Help" set msg { Use SSL: The default, use SSL via STUNNEL (this requires SSL aware VNC server, e.g. x11vnc -ssl SAVE ...) See the description in the main Help panel. Use SSH: Instead of using STUNNEL SSL, use ssh(1) for the encrypted tunnel. You must be able to log in via ssh to the remote host. On Unix the cmdline ssh(1) program (it must already be installed) will be run in an xterm for passphrase authentication, prompts about RSA keys, etc. On Windows the cmdline plink.exe program will be launched in a Windows Console window. (Apologies for the klunkiness..) You can set the "VNC Host:Display" to "user@host:disp" to indicate ssh should log in as "user" on "host". NOTE: On Windows you *MUST* always supply the "user@" part (due to a plink deficiency). E.g.: VNC Host:Display: fred@far-away.east:0 Gateway: If an intermediate gateway machine must be used (e.g. to enter a firewall; the VNC Server is not running on it), put it in the Proxy/Gateway entry, e.g.: VNC Host:Display: workstation:0 Proxy/Gateway: user@gateway-host:port ssh is used to login to user@gateway-host and then a -L port redirection is set up to go to workstation:0 from gateway-host. ":port" is optional, use it if the gateway-host SSH port is not the default value 22. Chaining 2 ssh's: One can also do a "double ssh", i.e. a first SSH to the gateway login machine then a 2nd ssh to the destination machine (presumably it is running the vnc server). Unlike the above example, the "last leg" (gateway-host -> workstation) is also encrypted by SSH this way. Do this by splitting the gateway in two with a comma, the part before it is the first SSH: VNC Host:Display: localhost:0 Proxy/Gateway: user@gateway-host:port,user@workstation:port Web and SOCKS proxies can also be used with SSH: VNC Host:Display: user@workstation:0 Proxy/Gateway: socks://socks.server:1080 See the "SSH Proxies/Gateways" in the Main Help document for full details. Remote Command: In the "Remote SSH Command" entry you can to indicate that a remote command to be run. The default is "sleep 15" to make sure port redirections get established. But you can run anything else, for example, to run x11vnc on your X :0 workstation display: x11vnc -display :0 -nopw Windows SSH SERVER: if you are ssh'ing INTO Windows (e.g. CYGWIN SSHD server) there may be no "sleep" command so put in something like "ping localhost" or "ping -n 10 -w 1000 localhost" to set a short delay to let the port redir get established. Trick: If you use "SHELL" asl the "Remote SSH Command" then you get an SSH shell only: no VNC viewer will be launched. On Windows "PUTTY" will try to use putty.exe (better terminal emulation than plink.exe) A shortcut for this is Ctrl-S as long as user@hostname is present in the "VNC Host:Display" box. Use SSH + SSL: Tunnel the SSL connection through a SSH tunnel. Use this if you want end-to-end SSL and must use a SSH gateway (e.g. to enter a firewall) or if additional SSH port redirs are required (CUPS, Sound, SMB tunnelling: See Advanced Options). This is a RARELY used mode, but included in case the need arises. No Encryption: In '-noenc' mode, which is now the default, (Ctrl-E also toggles this mode), use this to make a Direct connection to the VNC Server with no encryption whatsoever. (Be careful about passwords, etc.) The -noenc mode is now the default since SSVNC 1.0.25, use the '-enc' cmdline option to disable the button. Automatically Find X Session: When using SSH mode to connect, you can select this option. It simply sets the Remote SSH Command to: PORT= x11vnc -find -localhost This requires that x11vnc is installed on the remote computer and is available in $PATH for the ssh login. The command "x11vnc -find -localhost" command is run on the remote machine. The -find option causes x11vnc to try to find an existing X session owned by the user (i.e. who you ssh in as). If it does it attaches to it; otherwise the x11vnc VNC server exits immediately followed by your VNC Viewer. The PORT= option just means to let x11vnc pick its own VNC port and then connect to whatever it picked. Use P= for more debugging output. The idea for this mode is you simply type 'username@workstation' in the VNC Host:Display box, Select 'Options -> Automatically Find X Session', and then click Connect. The tsvnc mode is similar (it runs x11vnc on the remote side with the intent of automatically finding, or creating, your desktop). Unix Username & Password: This is only available on Unix and MacOSX and when using the SSVNC enhanced TightVNC viewer (it has been modified to do Unix logins). It supports a login dialog with servers doing something like x11vnc's "-unixpw" mode. After any regular VNC authentication takes place (VNC Password), then it sends the Unix Username, a Return, the Unix Password and a final Return. This saves you from typing them into the "login:" and "Password:" prompts in the viewer window. Note that the x11vnc -unixpw login mode is external to the VNC protocol, so you need to be sure the VNC server is in this mode and will be waiting for the dialog. Otherwise the username and password will be typed directly into the desktop application that happens to have the focus! When you select this option "Unix Username:" and "Unix Password:" entry boxes appear on the main panel where you can type them in. x11vnc has settings that can be specified after a ":" in the Unix username; they may be used here as well. (For example: username:3/4,nc for a smaller screen and -nocache) If the Unix Username is not set when you click Connect, then any SSH username@host is used. Otherwise the environment variable $USER or $LOGNAME and finally whoami(1) is used. Also Note that the Unix Password is never saved in a VNC profile (so you have to type it each time). Also, the remote x11vnc server is instructed to not echo the Username string by sending an initial Escape. Set the SSVNC_UNIXPW_NOESC=1 environment variable to override this. Reverse VNC Connection: Reverse (listening) VNC connections are possible as well. Enable with this button "Reverse VNC Connection (-LISTEN)" In this case the VNC Server initiates the connection to your waiting (i.e. listening) SSVNC viewer. For SSL connections in the 'VNC Host:Display' entry box put in the number (e.g. "0" or ":0" or ":1", etc.) that corresponds to the Listening display (0 -> port 5500, 1 -> port 5501, etc.) you want to use. For example x11vnc can then be used via: "x11vnc ... -ssl SAVE -connect hostname:port" using the "port" with the one you chose. Clicking on the 'Listen' button puts your SSVNC viewer in a "listening" state on that port number, waiting for a connection from the VNC Server. Then a VNC server should establish a reverse connection to that port on this machine (e.g. -connect this-machine:5500 or -connect this-machine:5503, etc.) Server SSL certificates will be verified, however you WILL NOT be prompted about unrecognized ones; rather, you MUST set up the correct Server certificate (e.g. by importing). prior to any connections. If the connection is failing in Reverse VNC (listening) mode, check the STUNNEL log output to see if STUNNEL is unable to authenticate the VNC Server. If you want to allow in a reverse connection with NO Server authentication, unset the 'Verify All Certs' option. When listening in SSL, you will ALSO need to specify YOUR OWN SSL cert, "MyCert", or otherwise let the GUI prompt you to create a "listen.pem" and use that. The "listen.pem" will be reused in later SSL Listening connections unless you specify a different one with MyCert. On Windows or using a 3rd party VNC Viewer multiple, simultaneous reverse connections are always enabled. On Unix/MacOSX with the provided ssvncviewer they are disabled by default. To enable them: Options -> Advanced -> Unix ssvncviewer -> Multiple LISTEN Conns. For reverse connections in SSH or SSH + SSL modes it is a little trickier. The SSH tunnel (with -R tunnel) must be established and remain up waiting for reverse connections. The default time is "sleep 1800", i.e. 30 mins. You can put a longer or shorter sleep in "Remote SSH Command" (perhaps after your command runs: cmd; sleep 3600). For SSH reverse connections put "hostname:n" in 'VNC Host:Display' or "user@hostname:n". The "n" will be the listening display on the *REMOTE* side. So to have the remote x11vnc connect use: "x11vnc ... -connect localhost:n" or "x11vnc -R connect:localhost:n" (-ssl will be needed for SSH+SSL mode). If the -R port cannot be opened because it is in use by another program you will have to kill everything and start over using a different port. In reverse connections mode be careful to protect the listening VNC Viewer from direct connections (neither SSL nor SSH) connecting directly to its listening port thereby bypassing the tunnel. This can be done by a host-level firewall that only lets in, say, port 5500 (the default one ":0" for stunnel to listen on). Or for SSH reverse connections allow NO 5500+n ports in. For reverse connections, the Unix enhanced tightvnc viewers supplied in the SSVNC package will only listen on localhost so these precautions are not needed. Specify a specific interface, e.g. 192.168.1.1:0 to have stunnel only listen on that interface. IPv6 works too, e.g. :::0 or ::1:0 Also works for UN-encrypted reverse connections as well ('None'). Note that for SSL connections use of "Proxy/Gateway" does not make sense: the remote side cannot initiate its reverse connection via the Proxy. Note that for SSH or SSH+SSL connections use of "Proxy/Gateway" does not make sense (the ssh cannot do a -R on a remote host:port), unless it is a double proxy where the 2nd host is the machine with the VNC server. View Only: Have VNC Viewer ignore mouse and keyboard input. Fullscreen: Start the VNC Viewer in fullscreen mode. Raise On Beep: Deiconify viewer when bell rings. Use 8bit color: Request a very low-color pixel format. Do not use JPEG: Do not use the jpeg aspect of the tight encoding. Use X11 vncviewer on MacOSX: On MacOSX try to use the bundled X11 vncviewer instead of the Chicken of the VNC viewer; The Xquartz X server must be installed (it is by default on 10.5.x) and the DISPLAY variable must be set (see Tip 15 of Help to do this manually.) Put cotvnc=1 in ~/.ssvncrc to switch the default. Kill Stunnel Automatically: On Windows, automatically try to kill the STUNNEL process when the VNC Viewer exits. This is a global setting (not per-profile); it can be also set via either the -killstunnel cmdline option, or killstunnel=1 in ssvnc_rc. To disable it supply -nokillstunnel or put killstunnel=0 in ssvnc_rc. As of 1/2009 this option is on by default. The main drawback to having STUNNEL automatically killed is that you will not be able to view its logfile. If you are having trouble connecting via SSL, disable this option and double click on the dark green STUNNEL icon in the tray to view the log. Compress Level/Quality: Set TightVNC encoding parameters. Putty PW: On Windows only: use the supplied password for plink SSH logins. Unlike the other options the value is not saved when 'Save' is performed. This feature is useful when options under "Advanced" are set that require TWO SSH's: you just have to type the password once in this entry box. The bundled pageant.exe and puttygen.exe programs can also be used to avoid repeatedly entering passwords (note this requires setting up and distributing SSH keys). Start up pageant.exe or puttygen.exe and read the instructions there. Note, that there is a small exposure to someone seeing the putty password on the plink command line. Note that the Putty PW is not cleared if you load in a new VNC profile. Port Slot: On Windows ports cannot be selected or checked as easily as on Unix. So listening ports for ssh redirs, proxy tunnelling, and etc. things are picked via finding a free "slot". The slots run from 30 to 99 and are locked based on the existence of a file with the slot number in it. When the connection is about to be made, a free slot is found and used to work out some ports (e.g. 5930 for the local VNC port, etc.) This way simultaneous SSVNC connections can take place. One drawback of this is that Putty/Plink stores SSH keys based on hostname:port, and with a proxy tunnel the hostname is "localhost". So the Putty key store may have key collisions for the localhost tunnels, and plink will prompt you to resolve the conflict WRT a different SSH key being discovered. To work around this to some degree you can select a unique Port Slot (in the range 50-99) for a specific host. Then the ssh redir port to this host will never change and so the Putty localhost:fixed-port key should remain valid. Mode: To change the GUI Mode, select between the full SSVNC (i.e. SSL and SSH), SSHVNC (i.e. SSH-Only), and Terminal Services mode (TSVNC; uses x11vnc) Note: You can put "mode=tsvnc" or "mode=sshvnc" in your ~/.ssvncrc file (ssvnc_rc on Windows) to have the application start up in the given mode. Show 'No Encryption' Option: Note: since SSVNC 1.0.25 the 'No Encryption' Option is enabled by default. Select this to display a button that disables both SSL and SSH encryption. This is the same as Ctrl+E. This puts a check item "None" on the main panel and also a "No Encryption" check item in the "Options" panel. If you select this item, there will be NO encryption for the VNC connection (use cautiously) See Tip 5) under Help for more information about disabling encryption. Buttons: Use Defaults: Set all options to their defaults (i.e. unset). Delete Profile: Delete a saved profile. Advanced: Bring up the Advanced Options dialog. Save and Load: You can Save the current settings by clicking on Save (.vnc file) and you can also read in a saved one with Load Profile. Use the Browse... button to select the filename via the GUI. Pressing Ctrl-L or Clicking the Right mouse button on the main GUI will invoke the Load dialog. Note: On Windows since the TightVNC Viewer will save its own settings in the Registry, some unexpected behavior is possible because the viewer is nearly always directed to the VNC host "localhost:30". E.g. if you specify "View Only" in this gui once but not next time the Windows VNC Viewer may remember the setting. Unfortunately there is not a /noreg option for the Viewer. } .oh.f.t insert end $msg jiggle_text .oh.f.t } proc help_fetch_cert {{selfsigned 1}} { toplev .fh set h 35 if [small_height] { set h 28 } scroll_text_dismiss .fh.f 85 $h center_win .fh wm resizable .fh 1 0 wm title .fh "Fetch Certificates Help" set msg { The displayed SSL Certificate has been retrieved from the VNC Server via the "Fetch Cert" action.

On Unix the openssl(1) program must be installed and in $PATH. On Windows, a copy of the openssl program is provided for convenience. The resulting certificate files can be used for either: 1) authenticating yourself (VNC Viewer) to a VNC Server or 2) your verifying the identity of a remote VNC Server. In either case you will need to safely copy one of the generated key or certificate files to the remote VNC Server and have the VNC Server use it. Or you could send it to the system administrator of the VNC Server. For the purpose of description, assume that the filename selected in the "Save to file" entry is "vnccert.pem". That file will be generated by this process and so will the "vnccert.crt" file. "vnccert.pem" contains both the Private Key and the Public Certificate. "vnccert.crt" only contains the Public Certificate. For case 1) you would copy "vnccert.crt" to the VNC Server side and instruct the server to use it. For x11vnc it would be for example: x11vnc -sslverify /path/to/vnccert.crt -ssl SAVE ... (it is also possible to handle many client certs at once in a directory, see the -sslverify documentation). Then you would use "vnccert.pem" as the MyCert entry in the SSL Certificates dialog. For case 2) you would copy "vnccert.pem" to the VNC Server side and instruct the server to use it. For x11vnc it would be for example: x11vnc -ssl /path/to/vnccert.pem Then you would use "vnccert.crt" as the as the ServerCert entry in the "SSL Certificates" dialog. Creating the Certificate: Choose a output filename (ending in .pem) in the "Save to file" entry. Then fill in the identification information (Country, State or Province, etc). The click on "Create" to generate the certificate files. Encrypting the Private Key: It is a very good idea to encrypt the Private Key that goes in the "vnccert.pem". The downside is that whenever that key is used (e.g. starting up x11vnc using it) then the passphrase will need to be created. If you do not encrypt it and somebody steals a copy of the "vnccert.pem" file then they can pretend to be you. After you have created the certificate files, you must copy and import either "vnccert.pem" or "vnccert.pem" to the remote VNC Server and also select the other file in the "SSL Certificates" dialog. See the description above. For more information see: http://www.karlrunge.com/x11vnc/ssl.html http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-tunnel-int The first one describes how to use x11vnc to create Certificate Authority (CA) certificates in addition to Self-Signed ones. Tip: if you choose the "Common Name" to be the internet hostname (e.g. gateway.mydomain.com) that connections will be made to or from that will avoid many dialogs when connecting mentioning that the hostname does not match the Common Name. } .ccrt.f.t insert end $msg global ccert ccert_init tcert if {!

You may need also to adjust your VNC Viewer to not show this region (the SSVNC Unix viewer does it automatically). The scheme uses a lot of RAM, but at least it has the advantage that it works with every VNC Viewer. Otherwise the VNC protocol would need to be modified, changing both the server and the viewer. Set the x11vnc "-ncache" parameter to an even integer between 2 and 20. This is the increase in area factor over the normal screen for the caching region.

For CUPS printing redirection to work properly, you MUST enable it for the connection that *creates* your terminal services X session (i.e. the first connection.) You cannot retroactively enable CUPS redirection on an already existing terminal services X session. (See CUPS printing for normal SSVNC mode for how you might do that.) Enter the VNC Viewer side (i.e. where you are sitting) CUPS server under "Local CUPS Server". Use "localhost:631" if there is one on your viewer machine (normally the case if you set up a printer on your unix or macosx system), or, e.g., "my-print-srv:631" for a nearby CUPS print server. Note that 631 is the default CUPS port. (On MacOSX it seems better to use "127.0.0.1" instead of "localhost".) The SSVNC Terminal Services created remote Desktop session will have the variables CUPS_SERVER and IPP_PORT set so all printing applications will be redirected to your local CUPS server. So your locally available printers should appear in the remote print dialogs. Windows/SMB Printers: Under "Local SMB Print Server" you can set a port redirection for a Windows (non-CUPS) SMB printer. If localhost:139 does not work, try the literal string "IP:139", or use the known value of the IP address manually. 139 is the default SMB port; nowadays 445 might be a better possibility. For Windows/SMB Printers if there is no local CUPS print server, it is usually a very good idea to make the CUPS Server setting EMPTY (to avoid desktop apps trying incessantly to reach the nonexistent CUPS server.) On the remote side, in the Desktop session the variables $SMB_SERVER, $SMB_HOST, and $SMB_PORT will be set for you to use. Unfortunately, printing to Windows may only ve partially functional due to the general lack PostScript support on Windows. If you have print admin permission on the remote machine you can configure CUPS to know about your Windows printer via lpadmin(8) or a GUI tool. You give it the URI: smb://localhost:port/printername or possibly: smb://localhost:port/computer/printername "port" will be found in the $SMB_PORT. You also need to identify the printer type. NOTE: You will leave "Local CUPS Server" blank in this case. The smbspool(1) command should also work as well, at least for PostScript printers.

This will be either of the "Use SSH" or "SSH+SSL" modes. NOTE: For pure SSL tunnelling it currently will not work. This method requires working CUPS software setups on BOTH the remote and local sides of the connection. If the remote VNC server is Windows you probably cannot SSH into it anyway... If you can, you will still need to set up a special printer TCP port redirection on your own. Perhaps adding and configuring a "Unix Printer" under Windows (like Method #2 below) will work. If the local machine (SSVNC side) is Windows, see the bottom of this help for redirecting to SMB printers. If the remote VNC server is Mac OS X this method may or may not work. Sometimes applications need to be restarted to get them to notice the new printers. Adding and configuring a special "Unix Printer", (Method #2) below, might yield more reliable results at the cost of additional setup and permissions. For Unix/Linux remote VNC servers, applications may also need to be restarted to notice the new printers. The only case known to work well is the one where the remote side has no CUPS printers configured. As mentioned above, see Method #2 for another method. ************************************************************************* *** Directions: You choose your own remote CUPS redir port below under "Use Remote CUPS Port". 6631 is our default and is used in the examples below. Use it or some random value greater than 1024. Note that the standard CUPS server port is 631. The port you choose must be unused on the VNC server machine (it is NOT checked for you). Print requests connecting to it are redirected to your local VNC viewer-side CUPS server through the SSH tunnel. (Note: root SSH login permission is needed for ports less than 1024, e.g. 631; this is not recommended, use something around 6631 instead). Then enter the VNC Viewer side (i.e. where you are sitting) CUPS server into "Local CUPS Server". A good choice is the default "localhost:631" if there is a cups server on your viewer machine (this is usually the case if you have set up a printer). Otherwise enter, e.g., "my-print-srv:631" for your nearby (viewer-side) CUPS print server. The "Manage 'ServerName' in the $HOME/.cups/client.conf file for me" setting below is enabled by default. It should handle most situations. What it does is modify the .cups/client.conf file on the VNC server-side to redirect the print requests while the SSVNC viewer is connected. When SSVNC disconnects .cups/client.conf is restored to its previous setting. If, for some reason, the SSVNC CUPS script fails to restore this file after SSVNC disconnects, run this command on the remote machine: cp $HOME/.cups/client.conf.back $HOME/.cups/client.conf to regain your initial printing configuration. You can also use CUPS on the VNC server-side to redirect to Windows (SMB) printers. See the additional info for Windows Printing at the bottom of this help. In case the default method (automatic .cups/client.conf modification) fails, we describe below all of the possible methods that can be tried. As noted above, you may need to restart applications for them to notice the new printers or for them to revert to the original printers. If this is not acceptable, consider Method #2 below if you have the permission and ability to alter the print queues for this. ************************************************************************* *** Method #1: Manually create or edit the file $HOME/.cups/client.conf on the VNC server side by putting in something like this in it: ServerName localhost:6631 based on the port you set in this dialog's entry box. After the remote VNC Connection is finished, to go back to the non-SSH tunnelled CUPS server and either remove the client.conf file or comment out the ServerName line. This restores the normal CUPS server for you on the remote VNC server machine. Select "Manage 'ServerName' in the $HOME/.cups/client.conf file for me" to do this editing of the VNC server-side CUPS config file for you automatically. NOTE: It is now on by default (deselect it if you want to manage the file manually; e.g. you print through the tunnel only very rarely, or often print locally when the tunnel is up, etc.) Select "Pass -env FD_CUPS=<Port> to x11vnc command line" if you are starting x11vnc as the Remote SSH Command, and x11vnc is running in -create mode (i.e. FINDCREATEDISPLAY). That way, when your X session is created IPP_PORT will be set correctly for the entire session. This is the mode used for 'Terminal Services' printing. NOTE: You probably would never select both of the above two options at the same time, since they conflict with each other to some degree. ************************************************************************* *** Method #2: If you have admin permission on the VNC Server machine you can likely "Add a Printer" via a GUI dialog, a Wizard, CUPS Web interface (i.e. http://localhost:631/), lpadmin(8), etc. You will need to tell the dialog that the network printer located is at, e.g., localhost:6631, and anything else needed to identify the printer (type, model, etc). NOTE: sometimes it is best to set the model/type as "Generic / Postscript Printer" to avoid problems with garbage being printed out. For the URI to use, we have successfully used ones like this with CUPS: http://localhost:6631/printers/Deskjet-3840 ipp://localhost:6631/printers/Deskjet-3840 for an HP Deskjet-3840 printer. See the CUPS documentation for more about the URI syntax and pathname. This mode makes the client.conf ServerName parameter unnecessary (BE SURE TO DISABLE the "Manage 'ServerName' ... for me" option.) ************************************************************************* *** Method #3: Restarting individual applications with the IPP_PORT set will enable redirected printing for them, e.g.: env IPP_PORT=6631 firefox If you can only get this method to work, an extreme application would be to run the whole desktop, e.g. "env IPP_PORT=6631 gnome-session", but then you would need some sort of TCP redirector (ssh -L comes to mind), to direct it to 631 when not connected remotely. ************************************************************************* *** Windows/SMB Printers: Under "Local SMB Print Server" you can set a port redirection for a Windows (non-CUPS) SMB printer. E.g. port 6632 -> localhost:139. If localhost:139 does not work, try the literal string "IP:139", or insert the actual IP address manually. NOTE: Nowadays on Windows port 445 might be a better choice. For Windows printers, if there is no local CUPS print server, set the 'Local CUPS Server' and 'Use Remote CUPS Port' to be EMPTY (to avoid desktop apps trying incessantly to reach the nonexistent CUPS server.) You must enable Sharing for your local Windows Printer. Use Windows Printer configuration dialogs to do this. Next, you need to have sudo or print admin permission so that you can configure the *remote* CUPS to know about this Windows printer via lpadmin(8) or GUI Printer Configuration dialog, etc (Method #2 above). You basically give it the URI: smb://localhost:6632/printername For example, we have had success with GNOME CUPS printing configuration using: smb://localhost:6632/HPOffice smb://localhost:6632/COMPUTERNAME/HPOffice where "HPOffice" was the name Windows shares the printer as. Also with this SMB port redir mode, as a last resort you can often print using the smbspool(8) program like this: smbspool smb://localhost:6632/printer job user title 1 "" myfile.ps You could put this in a script. For this URI, it appears only the number of copies ("1" above) and the file itself are important. If on the local (SSVNC viewer) side there is some nearby CUPS print server that knows about your Windows printer, you might have better luck with that instead of using SMB. Set 'Local CUPS Server' to it.

This will be either of the "Use SSH" or "SSH+SSL" modes. NOTE: For pure SSL tunnelling it currently will not work. This method requires working Sound daemon (e.g. ESD or ARTSD) software setups on BOTH the remote and local sides of the connection. Often this means you want to run your ENTIRE remote desktop with ALL applications instructed to use the sound daemon's network port. E.g. esddsp -s localhost:16001 startkde esddsp -s localhost:16001 gnome-session and similarly for artsdsp, etc. You put this in your ~/.xession, or other startup file. This is non standard. If you do not want to do this you still can direct *individual* sound applications through the tunnel, for example "esddsp -s localhost:16001 soundapp", where "soundapp" is some application that makes noise (say xmms or mpg123). Select "Pass -env FD_ESD=<Port> to x11vnc command line." if you are starting x11vnc as the Remote SSH Command, and x11vnc is running in -create mode (i.e. FINDCREATEDISPLAY). That way, your X session is started via "esddsp -s ... <session>" and the ESD variables will be set correctly for the entire session. (This mode make most sense for a virtual, e.g. Xvfb or Xdummy session, not one a physical display). Also, usually the remote Sound daemon must be killed BEFORE the SSH port redir is established (because it is listening on the port we want to use for the SSH redir), and, presumably, restarted when the VNC connection finished. One may also want to start and kill a local sound daemon that will play the sound received over the network on the local machine. You can indicate the remote and local Sound daemon commands below and how they should be killed and/or restart. Some examples: esd -promiscuous -as 5 -port 16001 -tcp -bind 127.0.0.1 artsd -n -p 7265 -F 10 -S 4096 -n -s 5 -m artsmessage -l 3 -f or you can leave some or all blank and kill/start them manually. For convenience, a Windows port of ESD is provided in the util/esound directory, and so this might work for a Local command: esound\esd -promiscuous -as 5 -port 16001 -tcp -bind 127.0.0.1 NOTE: If you indicate "Remote Sound daemon: Kill at start." below, then THERE WILL BE TWO SSH'S: THE FIRST ONE TO KILL THE DAEMON. So you may need to supply TWO SSH PASSWORDS, unless you are using something like ssh-agent(1), the Putty PW setting, etc. You will also need to supply the remote and local sound ports for the SSH redirs. For esd the default port is 16001, but you can choose another one if you prefer. For "Local Sound Port" you can also supply "host:port" instead of just a numerical port to specify non-localhost connections, e.g. to another nearby machine.

This will be either of the "Use SSH" or "SSH+SSL" modes. NOTE: For pure SSL tunnelling it currently will not work. This method requires a working Samba software setup on the remote side of the connection (VNC server) and existing Samba or Windows file server(s) on the local side (VNC viewer). The smbmount(8) program MUST be installed on the remote side. This evidently limits the mounting to Linux systems. Let us know of similar utilities on other Unixes. Mounting onto remote Windows machines is currently not supported (our SSH mode with services setup only works to Unix). On Debian and Ubuntu the smbmount program is currently in the package named 'smbfs'. Depending on how smbmount is configured you may be able to run it as a regular user, or it may require running under su(1) or sudo(8) (root password or user password required, respectively). You select which one you want via the checkbuttons below. In addition to a possible su(1) or sudo(8) password, you may ALSO need to supply passwords to mount each SMB share. This is an SMB passwd. If it has no password just hit enter after the "Password:" prompt. The passwords are supplied when the 1st SSH connection starts up; be prepared to respond to them. NOTE: USE OF SMB TUNNELLING MODE WILL REQUIRE TWO SSH'S, AND SO YOU MAY NEED TO SUPPLY TWO LOGIN PASSWORDS UNLESS YOU ARE USING SOMETHING LIKE ssh-agent(1) or the Putty PW setting. %WIN To indicate the Windows/Samba shares to mount enter them one per line in one of the forms: //machine1/share ~/Desktop/my-mount1 //machine2/fubar /var/tmp/my-foobar2 192.168.100.53:3456 1139 //machine3/baz /var/tmp/baz [...] The first part is the standard SMB host and share name //hostname/dir (note this share is on the local viewer-side not on the remote end). A leading '#' will cause the entire line to be skipped. The second part, e.g. /var/tmp/my-foobar2, is the directory to mount the share on the remote (VNC Server) side. You must be able to write to this directory. It will be created if it does not exist. A leading character ~ will be expanded to $HOME. So will the string %HOME. The string %USER will get expanded to the remote username. An optional part like 192.168.100.53:3456 is used to specify the real hostname or IP address, and possible non-standard port, on the local side if for some reason the //hostname is not sufficient. An optional leading numerical value, 1139 in the above example, indicates which port to use on the Remote side to SSH redirect to the local side. Otherwise a random one is tried (a unique one is needed for each SMB server:port combination). A fixed one is preferred: choose a free remote port. The standard SMB service ports (local side) are 445 and 139. 139 is used by this application. Sometimes "localhost" will not work on Windows machines for a share hostname, and you will have to specify a different network interface (e.g. the machine's IP address). If you use the literal string "IP" it will be attempted to replace it with the numerical IP address, e.g.: //machine1/share ~/Desktop/my-mount1 IP VERY IMPORTANT: Before terminating the VNC Connection, make sure no applications are using any of the SMB shares (or shells are cd-ed into the share). This way the shares will be automatically unmounted. Otherwise you will need to log in again, stop processes from using the share, become root and umount the shares manually ("smbumount /path/to/share", etc.) For more info see: http://www.karlrunge.com/x11vnc/faq.html#faq-smb-shares } set msg2 { To speed up moving to the next step, iconify the first SSH console when you are done entering passwords, etc. and then click on the main panel 'VNC Host:Display' label. } global is_windows if {! $is_windows} { regsub { *%WIN} $msg "" msg } else { set msg2 [string trim $msg2] regsub { *%WIN} $msg " $msg2" msg } .smb.f.t insert end $msg frame .smb.r label .smb.r.l -text "smbmount(8) auth mode:" -relief ridge radiobutton .smb.r.none -text "None" -variable smb_su_mode -value "none" radiobutton .smb.r.su -text "su(1)" -variable smb_su_mode -value "su" radiobutton .smb.r.sudo -text "sudo(8)" -variable smb_su_mode -value "sudo" pack .smb.r.l .smb.r.none .smb.r.sudo .smb.r.su -side left -fill x label .smb.info -text "Supply the mounts (one per line) below:" -anchor w -relief ridge eval text .smb.mnts -width 80 -height 5 $help_font .smb.mnts insert end $smb_mount_list button .smb.guess -text "Help me decide ..." -command {destroy .smb; smb_help_me_decide} button .smb.cancel -text "Cancel" -command {set use_smbmnt 0; destroy .smb} bind .smb <Escape> {set use_smbmnt 0; destroy .smb} wm protocol .smb WM_DELETE_WINDOW {set use_smbmnt 0; destroy .smb} button .smb.done -text "Done" -command {if {$use_smbmnt} {set_ssh; set smb_mount_list [.smb.mnts get 1.0 end]}; destroy .smb} pack .smb.done .smb.cancel .smb.guess .smb.mnts .smb.info .smb.r -side bottom -fill x pack .smb.f -side top -fill both -expand 1 center_win .smb } proc help_advanced_opts {} { toplev .ah scroll_text_dismiss .ah.f center_win .ah wm title .ah "Advanced Options Help" set msg { These Advanced Options that may require extra software installed on the VNC server-side (the remote server machine) and/or on the VNC client-side (where this gui is running). The Service redirection options, CUPS, ESD/ARTSD, and SMB will require that you use SSH for tunneling so that they can use the -R port redirection will be enabled for each service. I.e. "Use SSH" or "SSH + SSL" mode. These options may also require additional configuration to get them to work properly. Please submit bug reports if it appears it should be working for your setup but is not. Brief (and some not so brief) descriptions: CUPS Print tunnelling: Redirect localhost:6631 (say) on the VNC server to your local CUPS server. SSH mode is required. ESD/ARTSD Audio tunnelling: Redirect localhost:16001 (say) on the VNC server to your local ESD, etc. sound server. SSH mode is required. SMB mount tunnelling: Redirect localhost:1139 (say) on the VNC server and through that mount SMB file shares from your local server. The remote machine must be Linux with smbmount installed. SSH mode is required. Additional Port Redirs (via SSH): Specify additional -L port:host:port and -R port:host:port cmdline options for SSH to enable additional services. SSH mode is required. Automatically Find X Login/Greeter: This mode is similar to "Automatically Find X Session" except that it will attach to a X Login/Greeter screen that no one has logged into yet. It requires root privileges via sudo(1) on the remote machine. SSH mode is required. As with "Automatically Find X Session" it works only with SSH mode and requires x11vnc be installed on the remote computer. It simply sets the Remote SSH Command to: PORT= sudo x11vnc -find -localhost -env FD_XDM=1 An initial ssh running 'sudo id' is performed to try to 'prime' sudo so the 2nd one that runs x11vnc does not need a password. This may not always succeed... please mail us the details if it doesn't. See the 'X Login' description in 'Terminal Services' Mode Help for more info. Private SSH KnownHosts file: On Unix in SSH mode, let the user specify a non-default ssh known_hosts file to be used only by the current profile. This is the UserKnownHostsFile ssh option and is described in the ssh_config(1) man page. This is useful to avoid proxy 'localhost' SSH key collisions. Normally one should simply let ssh use its default file ~/.ssh/known_hosts for tracking SSH keys. The only problem that happens is when multiple SSVNC connections use localhost tunnel port redirections. These make ssh connect to 'localhost' on some port (where the proxy is listening.) Then the different keys from the multiple ssh servers collide when ssh saves them under 'localhost' in ~/.ssh/known_hosts. So if you are using a proxy with SSVNC or doing a "double SSH gateway" your ssh will connect to a proxy port on localhost, and you should set a private KnownHosts file for that connection profile. This is secure and avoids man-in-the-middle attack (as long as you actually verify the initial save of the SSH key!) The default file location will be: ~/.vnc/ssh_known_hosts/profile-name.known but you can choose any place you like. It must of course be unique and not shared with another ssh connection otherwise they both may complain about the key for 'localhost' changing, etc. SSH Local Port Protections: An LD_PRELOAD hack to limit the number of SSH port redirections to 1 and within the first 35 seconds. So there is a smaller window when the user can try to use your tunnel compared to the duration of your session. SSH mode is required. STUNNEL Local Port Protections: Try to prevent Untrusted Local Users (see the main Help panel) from using your STUNNEL tunnel to connect to the remote VNC Server. Change VNC Viewer: Specify a non-bundled VNC Viewer (e.g. UltraVNC or RealVNC) to run instead of the bundled TightVNC Viewer. Port Knocking: For "closed port" services, first "knock" on the firewall ports in a certain way to open the door for SSH or SSL. The port can also be closed when the encrypted VNC connection finishes. UltraVNC DSM Encryption Plugin: On Unix only, by using the supplied tool, ultravnc_dsm_helper, encrypted connections to UltraVNC servers using their plugins is enabled. Support for secret key encryption to Non-UltraVNC DSM servers is also supported, e.g. x11vnc -enc blowfish:my.key Do not Probe for VeNCrypt: Disable VeNCrypt auto-detection probe when not needed. By default in SSL mode an initial probe for the use of the VeNCrypt or ANONTLS protocol is performed. This is done during the initial fetch-cert action. Once auto-detected in the initial probe, the real connection to the VNC Server will use this information to switch to SSL/TLS at the right point in the VeNCrypt/ANONTLS handshake. In "Verify All Certs" mode initial the fetch-cert action is required so the automatic probing for VeNCrypt is always done. The fetch-cert is not needed if you specified a ServerCert or if you disabled "Verify All Certs". But by default the fetch-cert is done anyway to try to auto-detect VeNCrypt/ANONTLS. Set 'Do not Probe for VeNCrypt' to skip this unneeded fetch-cert action (and hence speed up connecting.) Use this if you know the VNC Server uses normal SSL and not VeNCrypt/ANONTLS. See also the next option, 'Server uses VeNCrypt SSL encryption' to if you know it uses VeNCrypt/ANONTLS (the probing will also be skipped if that option is set.) Server uses VeNCrypt SSL encryption: Indicate that the VNC server uses the VeNCrypt extension to VNC; it switches to an SSL/TLS tunnel at a certain point in the VNC Handshake. This is in constrast to the default ssvnc/x11vnc SSL tunnel behavior where the *entire* VNC traffic goes through SSL (i.e. it is vncs:// in the way https:// uses SSL) Enable this option if you know the server supports VeNCrypt. Also use this option for the older ANONTLS extension (vino). Doing so will give the quickest and most reliable connection to VeNCrypt/ANONTLS servers. If set, any probing to try to auto-detect VeNCrypt/ANONTLS will be skipped. Some VNC servers supporting VeNCrypt: VeNCrypt, QEMU, ggi, virt-manager, and Xen. Vino supports ANONTLS. The SSVNC VeNCrypt/ANONTLS support even works with 3rd party VNC Viewers you specify via 'Change VNC Viewer' (e.g. RealVNC, TightVNC, UltraVNC etc.) that do not directly support it. Note: many VeNCrypt servers only support Anonymous Diffie Hellman TLS which has NO built in authentication and you will also need to set the option described in the next section. If you are using VeNCrypt or ANONTLS for REVERSE connections (Listen) then you *MUST* set this 'Server uses VeNCrypt SSL encryption' option. Note also that REVERSE connections using VeNCrypt/ANONTLS currently do not work on Windows. Also, if you are using the "Use SSH+SSL" double tunnel to a VeNCrypt/ANONTLS server, you MUST set 'Server uses VeNCrypt SSL encryption' because "Verify All Certs" is disabled in SSH+SSL mode. Server uses Anonymous Diffie-Hellman Anonymous Diffie-Hellman can be used for SSL/TLS connections but there are no Certificates for authentication. Therefore only passive eavesdropping attacks are prevented, not Man-In-The-Middle attacks. Not recommended; try to use verified X509 certs instead. Enable this option if you know the server only supports Anon DH. When you do so, remember that ALL Certificate checking will be skipped (even if you have 'Verify All Certs' selected or set a ServerCert.) SSVNC may be able to autodetect Anon DH even if you haven't selected 'Server uses Anonymous Diffie-Hellman'. Once detected, it will prompt you whether it should continue. Set the 'Server uses Anonymous Diffie-Hellman' option to avoid trying autodetection (i.e. forcing the issue.) Note that most Anonymous Diffie-Hellman VNC Servers do so via the VeNCrypt or ANONTLS VNC extensions (see the previous section.) For these servers if you select 'Server uses Anonymous Diffie-Hellman' you *MUST* ALSO select 'Server uses VeNCrypt SSL encryption', otherwise SSVNC may have no chance to auto-detect the VeNCrypt/ANONTLS protocol. Also note, if you are using the "Use SSH+SSL" double tunnel to a VeNCrypt/ANONTLS server using Anon DH you MUST set 'Server uses Anonymous Diffie-Hellman' because "Verify All Certs" is disabled in SSH+SSL mode. Include: Default settings and Include Templates: Before explaining how Include works, first note that if you do not prefer some of SSVNC's default settings you can start up SSVNC and then change the settings for the options that you want to have a different default value. Then type "defaults" in VNC Host:Display entry box and press "Save" to save them in the "defaults.vnc" profile. After this, SSVNC will initialize all of the default values and then apply your override values in "defaults". For example, suppose you always want to use a different, 3rd party VNC Viewer. Set Options -> Advanced -> Change VNC Viewer to what you want, and then save it as the "defaults" profile. Now that default setting will apply to all profiles, and SSVNC in its startup state. To edit the defaults Load it, make changes, and then Save it. Delete the "defaults" profile to go back to no modifications. Note that defaults created and saved while defaults.vnc existed will NOT be automatically adjusted. Include Templates: Now suppose you have a certain class of settings that you do not want to always be applied, but you want them to apply to a group of profiles. For example, suppose you have some settings for very low bandwidth connections (e.g. low color modes and/or aggressive compression and quality settings.) Set these values in SSVNC and then in the VNC Host:Display entry box type in, say, "slowlink" and then press Save. This will save those settings in the template profile named "slowlink.vnc". Now to create a real profile that uses this template type the host:disp in "VNC Host:Display" and in Options -> Advanced -> Includes type in "slowlink". Then press Save to save the host profile. Then re-Load it. The "slowlink" settings will be applied after the defaults. Make any other changes to the setting for this profile and Save it again. Next time you load it in, the Include template settings will override the defaults and then the profile itself is read in. You may supply a comma or space separated list of templates to include. They are applied in the order listed. They can be full path names or basenames relative to the profiles directory. You do not need to supply the .vnc suffix. The non-default settings in them will be applied first, and then any values in the loaded Profile will override them. Sleep: Enter a number to indicate how many extra seconds to sleep while waiting for the VNC viewer to start up. On Windows this can give extra time to enter the Putty/Plink password, etc. Putty Args: Windows only, supply a string to be added to all plink.exe and putty.exe commands. Example: -i C:\mykey.ppk Launch Putty Pagent: Windows only, launch the Putty key agent tool (pageant) to hold your SSH private keys for automatic logging in by putty/plink. Launch Putty Key-Gen: Windows only, launch the Putty key generation tool (puttygen) to create new SSH private keys. Unix ssvncviewer: Display a popup menu with options that apply to the special Unix SSVNC VNC Viewer (perhaps called 'ssvncviewer') provided by this SSVNC package. This only applies to Unix or Mac OS X. Use ssh-agent: On Unix only: restart the GUI in the presence of ssh-agent(1) (e.g. in case you forgot to start your agent before starting this GUI). An xterm will be used to enter passphrases, etc. This can avoid repeatedly entering passphrases for the SSH logins (note this requires setting up and distributing SSH keys). About the CheckButtons: Ahem, Well...., yes quite a klunky UI: you have to toggle the CheckButton to pull up the Dialog box a 2nd, etc. time... don't worry your settings will still be there! } .ah.f.t insert end $msg jiggle_text .ah.f.t } proc help_ssvncviewer_opts {} { toplev .av scroll_text_dismiss .av.f center_win .av wm title .av "Unix SSVNC viewer Options Help" set msg { These Unix SSVNC VNC Viewer Options apply only on Unix or Mac OS X when using the viewer (ssvncviewer) supplied by this SSVNC package. Brief descriptions: Multiple LISTEN Connections: Allow multiple VNC servers to reverse connect at the same time and so display each of their desktops on your screen at the same time. Listen Once: Try to have the VNC Viewer exit after the first listening connection. (It may not always be detected; use Ctrl-C to exit) Listen Accept Popup Dialog: In -listen (reverse connection listening) mode when a reverse VNC connection comes in show a popup asking whether to Accept or Reject the connection. (-acceptpopup vncviewer option.) Accept Popup UltraVNC Single Click: As in 'Listen Accept Popup Dialog', except assume the remote VNC server is UltraVNC Single Click and force the execution of the protocol to retrieve the extra remote-side info (Windows User, ComputerName, etc) which is then also displayed in the Popup window. (-acceptpopupsc vncviewer option.) Use X11 Cursor: When drawing the mouse cursor shape locally, use an X11 cursor instead of drawing it directly into the framebuffer. This can sometimes give better response, and avoid problems under 'Scaling'. Disable Bell: Disable beeps coming from remote side. Use Raw Local: Use the VNC Raw encoding for 'localhost' connections (instead of assuming there is a local tunnel, SSL or SSH, going to the remote machine. Avoid Using Terminal: By default the Unix ssvncviewer will prompt for usernames, passwords, etc. in the terminal it is running inside of. Set this option to use windows for messages and prompting as much as possible. Messages will also go to the terminal, but all prompts will be done via popup window. Note that stunnel(1) may prompt for a passphrase to unlock a private SSL key. This is fairly rare because it is usually for Client-side SSL authentication. stunnel will prompt from the terminal; there seems to be no way around this. Also, note that ssh(1) may prompt for an ssh key passphrase or Unix password. This can be avoided in a number of ways, the simplest one is to use ssh-agent(1) and ssh-add(1). However ssh(1) may also prompt you to accept a new public key for a host or warn you if the key has changed, etc. Use Popup Fix: Enable a fix that warps the popup (F8) to the mouse pointer. Use XGrabServer (for fullscreen): On Unix only, use the XGrabServer workaround for older window managers. Sometimes also needed on recent (2008) GNOME. This workaround can make going into/out-of Fullscreen work better. Cursor Alphablending: Use the x11vnc alpha hack for translucent cursors (requires Unix, 32bpp and same endianness) TurboVNC: If available on your platform, use a ssvncviewer compiled with TurboVNC support. This is based on the VirtualGL project: http://www.sourceforge.net/projects/virtualgl You will need to install the VirtualGL's TurboJPEG library too. Currently (May/2009) only Linux.i686, Linux.x86_64, and Darwin.i386 have vncviewer.turbovnc binaries shipped in the ssvnc bundles. See the build instructions for how you might compile your own. Disable Pipelined Updates: Disable the TurboVNC-like pipelined updates mode. Pipelined updates is the default even when not TurboVNC enabled. They ask for the next screen update before the current one has finished downloading, and so this might reduce the slowdown due to high latency or low bandwidth by 2X or so. Disable them if they cause problems with the remote VNC Server or use too much bandwidth. Send CLIPBOARD not PRIMARY: When sending locally selected text to the VNC server side, send the CLIPBOARD selection instead of the PRIMARY selection. Send Selection Every time: Send selected text to the VNC server side every time the mouse focus enters the main VNC Viewer window instead only when it appears to have changed since the last send. Scaling: Use viewer-side (i.e. local) scaling of the VNC screen. Supply a fraction, e.g. 0.75 or 3/4, or a WxH geometry, e.g. 1280x1024, or the string 'fit' to fill the current screen. Use 'auto' to scale the desktop to match the viewer window size. If you observe mouse trail painting errors try using X11 Cursor. Note that since the local scaling is done in software it can be slow. Since ZRLE is better than Tight in this regard, when scaling is detected, the encoding will be switched to ZRLE. Use the Popup to go back to Tight if you want to, or set the env. var. SSVNC_PRESERVE_ENCODING=1 to disable the switch. For additional speedups under local scaling: try having a solid desktop background on the remote side (either manually or using 'x11vnc -solid ...'); and also consider using client side caching 'x11vnc -ncache 10 ...' if the remote server is x11vnc. Escape Keys: Enable 'Escape Keys', a set of modifier keys that, if all are pressed down, enable local Hot Key actions. Set to 'default' to use the default (Alt_L,Super_L on unix, Control_L,Meta_L on macosx) or set to a list of modifier keys. Y Crop: This is for x11vnc's -ncache client side caching scheme with our Unix TightVNC viewer. Sets the Y value to "crop" the viewer size at (below the cut is the pixel cache region you do not want to see). If the screen is tall (H > 2*W) ycropping will be autodetected, or you can set to -1 to force autodection. Otherwise, set it to the desired Y value. You can also set the scrollbar width (very thin by default) by appending ",sb=N" (or use ",sb=N" by itself to just set the scrollbar width). ScrollBar Width: This is for x11vnc's -ncache client side caching scheme with our Unix TightVNC viewer. For Y-Crop mode, set the size of the scrollbars (often one want it to be very narrow, e.g. 2 pixels to be less distracting. RFB Version: Set the numerical version of RFB (VNC) protocol to pretend to be, 3.x. Usually only needed with UltraVNC servers. Encodings: List encodings in preferred order, for example 'copyrect zrle tight' The list of encodings is: copyrect tight zrle zywrle hextile zlib corre rre raw Extra Options: String of extra Unix ssvncviewer command line options. I.e. for ones like -16bpp that cannot be set inside this SSVNC GUI. For a list click Help then 'SSVNC vncviewer -help Output'.

On Unix, for STUNNEL SSL tunnels we provide two options as extra safeguards against untrusted local users. Both only apply to Unix/MacOSX. Note that Both options are *IGNORED* in reverse connection (Listen) mode. 1) The first one 'Use stunnel EXEC mode' (it is mutually exclusive with option 2). For this case the modified SSVNC Unix viewer must be used: it execs the stunnel program instead of connecting to it via TCP/IP. Thus there is no localhost listening port involved at all. This is the best solution for SSL stunnel tunnels, it works well and is currently enabled by default. Disable it if there are problems. 2) The second one 'Use stunnel IDENT check', uses the stunnel(8) 'ident = username' to use the local identd daemon (IDENT RFC 1413 http://www.ietf.org/rfc/rfc1413.txt) to check that the locally connecting program (the SSVNC vncviewer) is being run by your userid. See the stunnel(8) man page for details. Normally the IDENT check service cannot be trusted much when used *remotely* (the remote host may be have installed a modified daemon). However when using the IDENT check service *locally* it should be reliable. If not, it means the local machine (where you run SSVNC) has already been root compromised and you have a serious problem. Enabling 'Use stunnel IDENT check' requires a working identd on the local machine. Often it is not installed or enabled (because it is not deemed to be useful, etc). identd is usually run out of the inetd(8) super-server. Even when installed and running it is often configured incorrectly. On a Debian/lenny system we actually found that the kernel module 'tcp_diag' needed to be loaded!

SSVNC uses STUNNEL for its SSL encryption, and STUNNEL uses the OpenSSL SSL implementation. This causes some problems with non-OpenSSL implementations on the VNC server side. The most noticable one is the UltraVNC Single Click III (SSL) server: http://www.uvnc.com/pchelpware/SCIII/index.html It can make a reverse connection to SSVNC via an encrypted SSL tunnel. Unfortunately, in the default operation with STUNNEL the connection will be dropped after 2-15 minutes due to an unexpected packet. Because of this, by default SSVNC will enable some SSL workarounds to make connections like these work. This is the STUNNEL 'options = ALL' setting: it enables a basic set of SSL workarounds. You can read all about these workarounds in the stunnel(8) manpage and the OpenSSL SSL_CTX_set_options(3) manpage. Why are we mentioning this? STUNNELS's 'options = ALL' lowers the SSL security a little bit. If you know you do not have an incompatible SSL implementation on the server side (e.g. any one using OpenSSL is compatible, x11vnc in particular), then you can regain that little bit of security by selecting the "Disable SSL Workarounds" option.

More info at: http://www.uvnc.com/features/encryption.html IMPORTANT: The UltraVNC DSM MSRC4, ARC4, and AESV2 implementations contain unfixed errors that could allow an eavesdropper to recover the session key or traffic easily. They often do not provide strong encryption, but only provide basic obscurity instead. Do not use them with critical data. The newer SecureVNC Plugin does not suffer from these problems. See the bottom of this help text for how to use symmetric encryption with Non-UltraVNC servers (for example, x11vnc 0.9.5 or later). This mode does not suffer the shortcomings of the UltraVNC MSRC4, ARC4, and AESV2 implementations. You will need to specify the corresponding UltraVNC encryption key (created by you using an UltraVNC server or viewer). It is usually called 'rc4.key' (for MSRC4), 'arc4.key' (for ARC4), and 'aesv2.key' (for AESV2). Specify the path to it or Browse for it. Also, specify which type of plugin it is (or use 'guess' to have it guess via the before mentioned filenames). The choice "UVNC SC" enables a special workaround for use with UltraVNC Single Click and the MSRC4 plugin. It may not be needed on recent SC (e.g. from ~2009 and later; select "MSRC4" for these newer ones.) You can also specify pw=my-password instead of a keyfile. Use single quotes pw='....' if the password contains shell meta-characters `!$&*(){}[]|;<>? Use the literal string 'pw=VNCPASSWD' to have the VNC password that you entered into the 'VNC Password:' be used for the pw=... SSL and SSH tunnels do not apply in this mode (any settings are ignored.) Proxying works in this mode, as well as Reverse Connections (Listen) The choice "SecureVNC" refers to the SecureVNC Plugin using 128 bit AES or ARC4 with 2048 bit RSA key exchange described here: http://adamwalling.com/SecureVNC Note in its default mode SecureVNC is *Vulnerable* to Man-In-The-Middle attacks (encryption but no server authentication) so do not use it with critical data. In SecureVNC mode you do not need to supply a 'Ultra DSM Keyfile'. However, if you DO supply a keyfile filename (recommended) if that file does not exist you will be prompted if you want to save the UltraVNC server's RSA key in it. The key's MD5 checksum is displayed so that you can verify that the key is trusted. One way to print out the SecureVNC public key MD5 checksum is: openssl rsa -inform DER -outform DER -pubout -in ./Server_SecureVNC.pkey | dd bs=1 skip=24 | md5sum Then on subsequent connections, if you continue to specify this filename, the SecureVNCPlugin server's RSA key will be checked against the file's contents and if they differ the connection will be dropped. NOTE, However, if the SecureVNC keyfile ends in the string 'ClientAuth.pkey' then its contents are used for SecureVNC's normal Client Authentication dialog (you need to use Windows SecureVNCPlugin to generate this file on the server side, it is usually called "Viewer_ClientAuth.pkey", and then safely copy it to the viewer side.) If you want to do BOTH Client Auth and server RSA key storing (recommended), have the keyfile end in 'ClientAuth.pkey.rsa'; that way the file will be used for storing the server RSA key and then the '.rsa' is trimmed off and the remainder used for the SecureVNC Client Auth data filename. Note that despite its intentions, Client Authentication in the FIRST release of SecureVNC is still susceptible to Man-In-The-Middle attacks. Even when that is fixed, SecureVNC Client Authentication is still susceptible to "spoofing" attacks where the viewer user may be tricked into revealing his VNC or MS-Logon password if his connection is intercepted. It is recommended you verify and save the Server key (see above) in addition to using Client Authentication. UltraVNC DSM encryption modes are currently experimental because unfortunately the UltraVNC DSM plugin also modifies the RFB protocol(!), and so the SSVNC vncviewer had to be modified to support it. The tight, zlib, and some minor encodings currently do not work in this mode and are disabled. Note that this mode also requires the utility tool named 'ultravnc_dsm_helper' that should be included in your SSVNC kit. Select 'Non-Ultra DSM' to use symmetric encryption to a Non-UltraVNC server via a supported symmetric key cipher. x11vnc supports symmetric encryption via, e.g., "x11vnc -enc aesv2:./my.key". Extra ciphers are enabled for this mode (e.g. blowfish and 3des). 'UVNC SC' and SecureVNC do not apply in this mode. Note for the Non-Ultra DSM case it will also work with any VNC Viewer (i.e. selected by Options -> Advanced -> Change VNC Viewer) not only the supplied SSVNC vncviewer. For experts: You can also set the random salt size and initialization vector size in Salt,IV for example "8,16".

This is the UserKnownHostsFile ssh option and is described in the ssh_config(1) man page. This is useful to avoid proxy 'localhost' SSH key collisions. Normally one should simply let ssh use its default file ~/.ssh/known_hosts for tracking SSH keys. The only problem with that happens when multiple SSVNC connections use localhost tunnel port redirections. These make ssh connect to 'localhost' on some port (where the proxy is listening.) Then the different keys from the multiple ssh servers collide when ssh saves them under 'localhost' in ~/.ssh/known_hosts. So if you are using a proxy with SSVNC or doing a "double SSH gateway" your ssh will connect to a proxy port on localhost, and you should set a private KnownHosts file for that connection profile. This is secure and avoids man-in-the-middle attack (as long as you actually verify the initial save of the SSH key!) The default file location will be: ~/.vnc/ssh_known_hosts/profile-name.known but you can choose any place you like.

The first SSH port redirection connection is intended to be the one that tunnels your VNC Viewer to reach the remote server. You can adjust these defaults LIM_ACCEPT=1 LIM_ACCEPT_TIME=35 by setting those env. vars. to different values. Note that there is still a window of a few seconds the Untrusted Local User can try to connect before your VNC Viewer does. So this method is far from perfect. But once your VNC session is established, he should be blocked out. Test to make sure blocking is taking place. Do not use this option if you are doing SSH Service redirections 'Additional Port Redirections (via SSH)' that redirect a local port to the remote server via ssh -L.

This option only applies on Unix or MaOSX when using the supplied SSVNC vncviewer. If you specify your own VNC Viewer it has no effect. On Windows (only the stock TightVNC viewer is provided) it has no effect because the Windows SSVNC can ONLY do "Multiple LISTEN Connections". Similarly on MacOSX if the COTVNC viewer is used there is no effect. Rationale: To play it safe, the Unix vncviewer provided by SSVNC (ssvncviewer) only allows one LISTEN reverse connection at a time. This is to prohibit malicious people on the network from depositing as many desktops on your screen as he likes, even if you are already connected to VNC server you desire. For example, perhaps the malicious user could trick you into typing a password into the desktop he displays on your screen. This protection is not perfect, because the malicious user could try to reverse connect to you before the correct VNC server reverse connects to you. This is even more of a problem if you keep your SSVNC viewer in LISTEN mode but unconnected for long periods of time. Pay careful attention in this case if you are to supplying sensitive information to the remote desktop. Enable 'Multiple LISTEN Connections' if you want to disable the default protection in the Unix SSVNC vncviewer; i.e. allow multiple reverse connections simultaneously (all vnc viewers we know of do this by default) For more control, do not select 'Multiple LISTEN Connections', but rather set the env. var SSVNC_MULTIPLE_LISTEN=MAX:n to limit the number of simultaneous reverse connections to "n" } .multil.t insert end $msg button .multil.cancel -text "Cancel" -command {set multiple_listen 0; destroy .multil} bind .multil <Escape> {set multiple_listen 0; destroy .multil} wm protocol .multil WM_DELETE_WINDOW {set multiple_listen 0; destroy .multil} button .multil.done -text "Done" -command {destroy .multil} pack .multil.t .multil.cancel .multil.done -side top -fill x center_win .multil wm resizable .multil 1 0 } proc use_grab_dialog {} { global usg_grab toplev .usegrb wm title .usegrb "Use XGrabServer (for fullscreen)" global help_font eval text .usegrb.t -width 85 -height 29 $help_font apply_bg .usegrb.t set msg { On Unix, some Window managers and some Desktops make it difficult for the SSVNC Unix VNC viewer to go into full screen mode (F9) and/or return. Sometimes one can go into full screen mode, but then your keystrokes or Mouse actions do not get through. This can leave you trapped because you cannot inject input (F9 again) to get out of full screen mode. (Tip: press Ctrl-Alt-F2 for a console login shell; then kill your vncviewer process, e.g. pkill vncviewer; then Alt-F7 to get back to your desktop) We have seen this in some very old Window managers (e.g. fvwm2 circa 1998) and some very new Desktops (e.g. GNOME circa 2008). We try to work around the problem on recent desktops by using the NEW_WM interface, but if you use Fullscreen, you may need to use this option. The default for the SSVNC Unix VNC viewer is '-grabkbd' mode where it will try to exclusively grab the keyboard. This often works correctly. However if Fullscreen is not working properly, try setting this 'Use XGrabServer' option to enable '-graball' mode where it tries to grab the entire X server. This usually works, but can be a bit flakey. Sometimes toggling F9 a few times gets lets the vncviewer fill the whole screen. Sometimes tapping F9 very quickly gets it to snap in. If GNOME (or whatever desktop) is still showing its taskbars, it is recommended you toggle F9 until it isn't. Otherwise, it is not clear who gets the input.

Somewhat like "knocking" on the door with the correct sequence before it being opened (but not necessarily letting you in yet). It is also possible to have a single encrypted packet (e.g. UDP) payload communicate with the firewall instead of knocking on a sequence of ports. Only after the correct sequence of ports is observed by the firewall does it allow the IP address of the client to attempt to connect to the service. So, for example, instead of allowing any host on the internet to connect to your SSH service and then try to login with a username and password, the client first must "tickle" your firewall with the correct sequence of ports. Only then will it be allowed to connect to your SSH service at all. This does not replace the authentication and security of SSH, it merely puts another layer of protection around it. E.g., suppose an exploit for SSH was discovered, you would most likely have more time to fix/patch the problem than if any client could directly connect to your SSH server. For more information http://www.portknocking.org/ and http://www.linuxjournal.com/article/6811 Tip: If you just want to use the Port Knocking for an SSH shell and not for a VNC tunnel, then specify something like "user@hostname cmd=SHELL" (or "user@hostname cmd=PUTTY" on Windows) in the VNC Host:Display entry box on the main panel. This will do everything short of starting the viewer. A shortcut for this is Ctrl-S as long as user@hostname is present. Specifying the Knocks: In the text area below "Supply port knocking pattern" you put in the pattern of "knocks" needed for this connection. You can separate the knocks by commas or put them one per line. Each "knock" is of this form: [host:]port[/udp] [delay] In the simplest form just a numerical port, e.g. 5433, is supplied. Items inside [...] are optional and described below. The packet is sent to the same host that the VNC (or SSH) connection will be made to. If you want it to go to a different host or IP use the [host:] prefix. It can be either a hostname or numerical IP. A TCP packet is sent by default. If you need to send a UDP packet, the netcat (aka "nc") program must be installed on Unix (tcl/tk does not support udp connections). Indicate this with "/udp" following the port number (you can also use "/tcp", but since it is the default it is not necessary). (You can also use ":udp" to match the knockd syntax). See the example below. For convenience a Windows netcat binary is supplied. The last field, [delay], is an optional number of milliseconds to delay before continuing on to the next knock. Examples: 5433, 12321, 1661 fw.example.com:5433, 12321/udp 3000, 1661 2000 fw.example.com:5433 12321/udp 3000 1661 2000 Note how the first two examples separate their knocks via commas ",". The 3rd example is equivalent to the 2nd and splits them up by new lines. Note for each knock any second number (e.g. the "2000" in "1661 2000") is a DELAY in milliseconds, not a port number. If you had a comma separating them: "1661, 2000" that would mean two separate knocks: one to port 1661 followed by one to 2000 (with basically no delay between them). In examples 2 and 3, "fw.example.com" represents some machine other than the VNC/SSH host. By default, the VNC/SSH host is the one the packet is sent to. If one of the items is the string "FINISH", then the part before it is used prior to connecting and the part after is used once the connection is finished. This can be used, say, to close the firewall port. Example: 5433, 12321, FINISH, 7659, 2314 (or one can split them up via lines as above.) Advanced port knock actions: If the string in the text field contains anywhere the strings "CMD=", "CMDX=", or "SEND=", then splitting on commas is not done: it is only split on lines. Then, if a line begins CMD=... the string after the = is run as an external command. The command could be anything you want, e.g. it could be a port-knocking client that does the knocking, perhaps encrypting the "knocks" pattern somehow or using a Single Packet Authorization method such as http://www.cipherdyne.com/fwknop/ Extra quotes (sometimes "'foo bar'") may be needed to preserve spaces in command line arguments because the tcl/tk eval(n) command is used. You can also use {...} for quoting strings with spaces. If a line begins CMDX=... then before the command is run the following tokens are expanded to strings: %IP Current machine's IP address (NAT may make this not useful). %NAT Try to get effective IP by contacting http://www.whatismyip.com %HOST The remote host of the connection. %USER The current user. %SECS The current time in seconds (platform dependent). %MSECS Platform dependent time having at least millisecond granularity. Lines not matching CMD= or CMDX= are treated as normal port knocks but with one exception. If a line ends in SEND=... (i.e. after the [host:]port, etc., part) then the string after the = is sent as a payload for the tcp or udp connection to [host:]port. netcat is used for these SEND cases (and must be available on Unix). If newlines (\n) are needed in the SEND string, use %NEWLINE. Sending binary data is not yet supported; use CMD= with your own program. Advanced Examples: CMD=port_knock_client -password wombat33 CMDX=port_knock_client -password wombat33 -host %HOST -src %NAT fw.example.com:5433/udp SEND=ASDLFKSJDF More tricks: To temporarily "comment out" a knock, insert a leading "#" character. Use "sleep N" to insert a raw sleep for N milliseconds (e.g. between CMD=... items or at the very end of the knocks to wait). If a knock entry matches "delay N" the default delay is set to N milliseconds (it is 150 initially). One Time Pads: If the text contains a (presumably single) line of the form: PAD=/path/to/a/one/time/pad/file then that file is opened and the first non-blank line not beginning with "#" is used as the knock pattern. The pad file is rewritten with that line starting with a "#" (so it will be skipped next time). The PAD=... string is replaced with the read-in knock pattern line. So, if needed, one can preface the PAD=... with "delay N" to set the default delay, and one can also put a "sleep N" after the PAD=... line to indicate a final sleep. One can also surround the PAD= line with other knock and CMD= CMDX= lines, but that usage sounds a bit rare. Example: delay 1000 PAD=C:\My Pads\work-pad1.txt sleep 4000 Port knock only: If, in the 'VNC Host:Display' entry, you use "user@hostname cmd=KNOCK" then only the port-knocking is performed. A shortcut for this is Ctrl-P as long as hostname is present in the entry box. If it matches cmd=KNOCKF, i.e. an extra "F", then the port-knocking "FINISH" sequence is sent, if any. A shortcut for this Shift-Ctrl-P as long as hostname is present. } .pk.f.t insert end $msg label .pk.info -text "Supply port knocking pattern:" -anchor w -relief ridge eval text .pk.rule -width 80

It sets up an SSL or SSH tunnel to the remote VNC Server and then launches the VNC viewer (either the one provided or another one that you have specified) to use that encrypted tunnel to connect to the VNC Server. The use of Proxies and Gateways to make the connections is implemented. Once you have started the SSVNC gui, you can click on the buttons "Help", "Options -> Help", "Certs -> Help", etc. for much information on how to use and configure the tool. In short, you supply a VNC server "hostname:display" in the "VNC Host:Display" entry box and then press the "Connect" button to connect to the server via SSL (stunnel). E.g. "far-away.east:0". Port numbers are also allowed, e.g. far-away.east:5905. Or supply user@hostname:display and click on the "Use SSH" option, then press the "Connect" button to connect to the server via an SSH tunnel. E.g. "fred@far-away.east:0". Note it is also possible to disable the use of SSL/SSH encryption tunnels by using a vnc:// or Vnc:// prefix before host:display. Shift+Ctrl-E is a short-cut to add/remove it. See also the \fB-noenc\fR option below for the 'No Encryption' button. Normally you do not specify any command line options. You simply run \fBssvnc\fR and use the GUI that starts up. However, as shortcuts you can supply a VNC host:display (or host:port) on the command line to connect to immediately (the GUI is started and the connection is initiated). For example, "\fBssvnc far-away.east:0\fR" Instead of a host:display, you can specify the name of a saved profile to automatically load that profile and then connect to its server. For example "\fBssvnc far\fR", if you named the profile "far". You can use the \fB-profiles\fR option to list the profiles you have saved. The related commands \fBsshvnc\fR and \fBtsvnc\fR start up the GUI in simplified modes: SSH Only Mode, and Terminal Services Mode, respectively. See below and the application Help for more information on the modes. You can also place certain settings in your ~/.ssvncrc, see the SSVNC Help panel ('Tips') for more info. The \fB-cmd\fR option does not start the GUI, it runs the command line utility \fBssvnc_cmd\fR directly with the given arguments. \fBssvnc_cmd\fR can launch the viewer directly (\fB-viewer ...\fR) or, by default, the \fBss_vncviewer\fR SSL/SSH tunnel wrapper script. See its help output for more information. There are also some command line options described as follows. .SH OPTIONS .TP \fB\-help\fR, \fB\-h\fR Prints out to the terminal a brief description and the options. .TP \fB\--help\fR Starts up the GUI as though the 'Help' button was pressed to show the main Help panel. .TP \fB\-cmd\fR \fI[ssvnc_cmd-args]\fR Launch the ssvnc_cmd utility command directly (no GUI) with the given arguments (for use when ssvnc_cmd is not in one's PATH.) If neither ssvnc_cmd nor ssvncviewer is in PATH, one can launch the viewer directly via: ssvnc -cmd -viewer [viewer-args] .TP \fB\-profiles\fR List the saved SSVNC profiles you have created. A profile is a destination host with specific parameter settings. .TP \fB\-list\fR Same as \fB\-profiles\fR .TP \fB\-ssh\fR Start in "SSH Only Mode". No SSL aspects are shown. Same as running the command \fBsshvnc\fR .TP \fB\-ts\fR Start in "Terminal Services Mode". This is like "SSH Only Mode", but simpler and assumes \fBx11vnc\fR is available on the remote side to start and manage X and VNC sessions. Same as running the command \fBtsvnc\fR .TP \fB\-tso\fR Same as \fB-ts\fR "Terminal Services Mode", however never let the user leave this mode (no button to switch modes is provided.) Same as SSVNC_TS_ALWAYS=1. .TP \fB\-ssl\fR Force the full GUI Mode: both SSL and SSH. This is the default. Same as \fB-ss\fR. .TP \fB\-nv\fR Toggle the "Verify All Certs" button to be off at startup. .TP \fB\-nvb\fR Never show the "Verify All Certs" button. Same as SSVNC_NO_VERIFY_ALL_BUTTON=1. .TP \fB\-bigger\fR Make the Profile Selection Dialog window bigger. Same as SSVNC_BIGGER_DIALOG=1. .TP \fB\-noenc\fR Start off in a mode where a 'No Encryption' check button is present. You can toggle the mode with Ctrl-E. Same as SSVNC_DISABLE_ENCRYPTION_BUTTON=1. Or \fInoenc=1\fR in ~/.ssvncrc. Selecting no encryption is the same as the vnc:// and Vnc:// prefixes described below. The \fB\-noenc\fR mode is now the default, use \fB-enc\fR or \fInoenc=0\fR for the opposite behavior. .TP \fB\-killstunnel\fR On Windows, automatically terminate the STUNNEL process when the viewer exits instead of prompting you (same as \fIkillstunnel=1\fR in ssvnc_rc or toggle in Options menu) .TP \fB\-nokillstunnel\fR On Windows, disable \fB-killstunnel\fR mode. Same as \fIkillstunnel=0\fR in ssvnc_rc or toggle in Options menu. Note that \fB-killstunnel\fR mode is now the default. .TP \fB\-mycert\fR \fI/path/to/mycert.pem\fR Set the default "MyCert" to be \fI/path/to/mycert.pem\fR. Same as \fB-cert\fR. If the file does not exist, ~/.vnc/certs is prefixed and tried. You can also set \fImycert=/path/to/mycert.pem\fR in ~/.ssvncrc. .TP \fB\-cacert\fR \fI/path/to/cacert.crt\fR Set the default "ServerCert" to be \fI/path/to/cacert.crt\fR. Same as \fB-ca\fR. If the file does not exist, ~/.vnc/certs is prefixed and tried. You can also set \fIcacert=/path/to/cacert.crt\fR in ~/.ssvncrc. .TP \fB\-crl\fR \fI/path/to/mycrl.pem\fR Set the default Certificate Revocation List to be \fI/path/to/mycrl.pem\fR. If the file does not exist, ~/.vnc/certs is prefixed and tried. You can also set \fIcrl=/path/to/mycrl.pem\fR in ~/.ssvncrc. .SH URL NOTATION Here are all of our URL-like prefixes that you can put in front of host:display (or host:port): For SSL: vncs:// vncssl:// and vnc+ssl:// For SSH: vncssh:// and vnc+ssh:// For No Encryption: vnc:// and Vnc:// Examples: To quickly make an SSL connection: \fBssvnc vncs://snoopy.com:0\fR To quickly make an SSH connection: \fBssvnc vnc+ssh://fred@snoopy.com:0\fR To quickly make a direct connection: \fBssvnc Vnc://snoopy.com:0\fR The above will also work in the "VNC Host:Display" entry box in the GUI. Press the "Connect" button after entering them. The difference between vnc:// and Vnc:// is that the latter one will not prompt you whether you really want to make an unencrypted connection or not. .SH FILES Your SSVNC vnc profiles are stored in the \fB$HOME/.vnc/profiles\fR directory. They end in suffix \fB.vnc\fR Your SSVNC vnc certificates and keys are stored in the \fB$HOME/.vnc/certs\fR directory. They typically end in \fB.pem\fR (both certificate and private key) or \fB.crt\fR (certificate only). You can put a few global parameters (e.g. mode=sshvnc) in your \fB$HOME/.ssvncrc\fR file (\fBssvnc_rc\fR on Windows); see the application Help for more information. .SH FONTS The following is from Tip 18 in the Help panel. Fonts: To change the tk fonts, set these environment variables before starting up ssvnc: SSVNC_FONT_DEFAULT and SSVNC_FONT_FIXED. For example: % env SSVNC_FONT_DEFAULT='helvetica -20 bold' ssvnc % env SSVNC_FONT_FIXED='courier -14' ssvnc or set both of them at once. To achieve the same effect, you can also set parameters in your ~/.ssvncrc file, for example: font_default=helvetica -20 bold font_fixed=courier -14 .SH SEE ALSO \fBssvncviewer\fB(1), \fBvncviewer\fR(1), \fBstunnel\fR(8), \fBssh\fR(1), \fBx11vnc\fR(1), \fBvncserver\fR(1) http://www.karlrunge.com/x11vnc http://www.karlrunge.com/x11vnc/ssvnc.html .SH AUTHORS Karl J.

It can connect to any VNC\-compatible server such as \fBXvnc\fR, WinVNC, or \fBx11vnc\fR, allowing you to control desktop environment of a different machine. ssvncviewer is an enhanced version of the tightvnc unix viewer that can take advantage of features in the \fBx11vnc\fR and UltraVNC VNC servers. See below for the description of these features. You can use F8 to display a pop\-up utility menu. Press F8 twice to pass single F8 to the remote side. .SH OPTIONS .TP \fB\-help\fR Prints a short usage notice to stderr. .TP \fB\-listen\fR Make the viewer listen on port 5500+\fIdisplay\fR for reverse connections from a server. WinVNC supports reverse connections using the "Add New Client" menu option, or the \-connect command line option. \fBXvnc\fR requires the use of the helper program \fBvncconnect\fR. .TP \fB\-via\fR \fIgateway\fR Automatically create encrypted TCP tunnel to the \fIgateway\fR machine before connection, connect to the \fIhost\fR through that tunnel (TightVNC\-specific). By default, this option invokes SSH local port forwarding, assuming that SSH client binary can be accessed as /usr/bin/ssh. Note that when using the \fB\-via\fR option, the host machine name should be specified as known to the gateway machine, e.g. "localhost" denotes the \fIgateway\fR, not the machine where vncviewer was launched. See the ENVIRONMENT section below for the information on configuring the \fB\-via\fR option. .TP \fB\-shared\fR When connecting, specify that a shared connection is requested. In TightVNC, this is the default mode, allowing you to share the desktop with other clients already using it. .TP \fB\-noshared\fR When connecting, specify that the session may not be shared. This would either disconnect other connected clients or refuse your connection, depending on the server configuration. .TP \fB\-viewonly\fR Disable transfer of mouse and keyboard events from the client to the server. .TP \fB\-fullscreen\fR Start in full\-screen mode. Please be aware that operating in full\-screen mode may confuse X window managers. Typically, such conflicts cause incorrect handling of input focus or make the viewer window disappear mysteriously. See the grabKeyboard setting in the RESOURCES section below for a method to solve input focus problem. .TP \fB\-noraiseonbeep\fR By default, the viewer shows and raises its window on remote beep (bell) event. This option disables such behaviour (TightVNC\-specific). .TP \fB\-user\fR \fIusername\fR User name for Unix login authentication. Default is to use current Unix user name. If this option was given, the viewer will prefer Unix login authentication over the standard VNC authentication. .TP \fB\-passwd\fR \fIpasswd\-file\fR File from which to get the password (as generated by the \fBvncpasswd\fR(1) program). This option affects only the standard VNC authentication. .TP \fB\-encodings\fR \fIencoding\-list\fR TightVNC supports several different compression methods to encode screen updates; this option specifies a set of them to use in order of preference. Encodings are specified separated with spaces, and must thus be enclosed in quotes if more than one is specified. Commas may be used to avoid spaces. Available encodings, in default order for a remote connection, are "copyrect tight hextile zlib corre rre raw". For a local connection (to the same machine), the default order to try is "raw copyrect tight hextile zlib corre rre". Raw encoding is always assumed as a last option if no other encoding can be used for some reason. For more information on encodings, see the section ENCODINGS below. .TP \fB\-bgr233\fR Always use the BGR233 format to encode pixel data. This reduces network traffic, but colors may be represented inaccurately. The bgr233 format is an 8\-bit "true color" format, with 2 bits blue, 3 bits green, and 3 bits red. .TP \fB\-owncmap\fR Try to use a PseudoColor visual and a private colormap. This allows the VNC server to control the colormap. .TP \fB\-truecolour\fR, \fB\-truecolor\fR Try to use a TrueColor visual. .TP \fB\-depth\fR \fIdepth\fR On an X server which supports multiple TrueColor visuals of different depths, attempt to use the specified one (in bits per pixel); if successful, this depth will be requested from the VNC server. .TP \fB\-compresslevel \fIlevel\fR Use specified compression \fIlevel\fR (0..9) for "tight" and "zlib" encodings (TightVNC\-specific). Level 1 uses minimum of CPU time and achieves weak compression ratios, while level 9 offers best compression but is slow in terms of CPU time consumption on the server side. Use high levels with very slow network connections, and low levels when working over high\-speed LANs. It's not recommended to use compression level 0, reasonable choices start from the level 1. .TP \fB\-quality \fIlevel\fR Use the specified JPEG quality \fIlevel\fR (0..9) for the "tight" encoding (TightVNC\-specific). Quality level 0 denotes bad image quality but very impressive compression ratios, while level 9 offers very good image quality at lower compression ratios. Note that the "tight" encoder uses JPEG to encode only those screen areas that look suitable for lossy compression, so quality level 0 does not always mean unacceptable image quality. .TP \fB\-nojpeg\fR Disable lossy JPEG compression in Tight encoding (TightVNC\-specific). Disabling JPEG compression is not a good idea in typical cases, as that makes the Tight encoder less efficient. You might want to use this option if it's absolutely necessary to achieve perfect image quality (see also the \fB\-quality\fR option). .TP \fB\-nocursorshape\fR Disable cursor shape updates, protocol extensions used to handle remote cursor movements locally on the client side (TightVNC\-specific). Using cursor shape updates decreases delays with remote cursor movements, and can improve bandwidth usage dramatically. .TP \fB\-x11cursor\fR Use a real X11 cursor with X-style cursor shape updates, instead of drawing the remote cursor on the framebuffer. This option also disables the dot cursor, and disables cursor position updates in non-fullscreen mode. .TP \fB\-autopass\fR Read a plain-text password from stdin. This option affects only the standard VNC authentication. .SH Enhanced TightVNC Viewer (SSVNC) OPTIONS .TP Enhanced TightVNC Viewer (SSVNC) web page is located at: .TP http://www.karlrunge.com/x11vnc/ssvnc.html .TP Note: ZRLE and ZYWRLE encodings are now supported. .TP Note: F9 is shortcut to Toggle FullScreen mode. .TP Note: In -listen mode set the env var. SSVNC_MULTIPLE_LISTEN=1 to allow more than one incoming VNC server at a time. This is the same as -multilisten described below. Set SSVNC_MULTIPLE_LISTEN=MAX:n to allow no more than "n" simultaneous reverse connections. If the host:port is specified as "exec=command args..." then instead of making a TCP/IP socket connection to the remote VNC server, "command args..." is executed and the viewer is attached to its stdio. This enables tunnelling established via an external command, e.g. an stunnel(8) that does not involve a listening socket. This mode does not work for -listen reverse connections. If the host:port is specified as "fd=n" then it is assumed n is an already opened file descriptor to the socket. (i.e the parent did fork+exec) If the host:port contains a '/' it is interpreted as a unix-domain socket (AF_LOCAL insead of AF_INET) .TP \fB\-multilisten\fR As in -listen (reverse connection listening) except allow more than one incoming VNC server to be connected at a time. The default for -listen of only one at a time tries to play it safe by not allowing anyone on the network to put (many) desktops on your screen over a long window of time. Use -multilisten for no limit. .TP \fB\-acceptpopup\fR In \fB\-listen\fR (reverse connection listening) mode when a reverse VNC connection comes in show a popup asking whether to Accept or Reject the connection. The IP address of the connecting host is shown. Same as setting the env. var. SSVNC_ACCEPT_POPUP=1. .TP \fB\-acceptpopupsc\fR As in \fB\-acceptpopup\fR except assume UltraVNC Single Click (SC) server. Retrieve User and ComputerName info from UltraVNC Server and display in the Popup. .TP \fB\-use64\fR In \fB\-bgr233\fR mode, use 64 colors instead of 256. .TP \fB\-bgr222\fR Same as \fB\-use64\fR. .TP \fB\-use8\fR In \fB\-bgr233\fR mode, use 8 colors instead of 256. .TP \fB\-bgr111\fR Same as \fB\-use8\fR. .TP \fB\-16bpp\fR If the vnc viewer X display is depth 24 at 32bpp request a 16bpp format from the VNC server to cut network traffic by up to 2X, then tranlate the pixels to 32bpp locally. .TP \fB\-bgr565\fR Same as \fB\-16bpp\fR. .TP \fB\-grey\fR Use a grey scale for the 16- and 8\fB\-bpp\fR modes. .TP \fB\-alpha\fR Use alphablending transparency for local cursors requires: x11vnc server, both client and server must be 32bpp and same endianness. .TP \fB\-scale\fR \fIstr\fR Scale the desktop locally. The string "str" can a floating point ratio, e.g. "0.9", or a fraction, e.g. "3/4", or WxH, e.g. 1280x1024. Use "fit" to fit in the current screen size. Use "auto" to fit in the window size. "str" can also be set by the env. var. SSVNC_SCALE. If you observe mouse trail painting errors, enable X11 Cursor mode (either via Popup or \fB\-x11cursor\fR.) Note that scaling is done in software and so can be slow and requires more memory. Some speedup Tips: ZRLE is faster than Tight in this mode. When scaling is first detected, the encoding will be automatically switched to ZRLE. Use the Popup menu if you want to go back to Tight. Set SSVNC_PRESERVE_ENCODING=1 to disable this. Use a solid background on the remote side. (e.g. manually or via x11vnc \fB\-solid\fR ...) If the remote server is x11vnc, try client side caching: x11vnc \fB\-ncache\fR 10 ... .TP \fB\-ycrop\fR n Only show the top n rows of the framebuffer. For use with x11vnc \fB\-ncache\fR client caching option to help "hide" the pixel cache region. Use a negative value (e.g. \fB\-1\fR) for autodetection. Autodetection will always take place if the remote fb height is more than 2 times the width. .TP \fB\-sbwidth\fR n Scrollbar width for x11vnc \fB\-ncache\fR mode (\fB\-ycrop\fR), default is very narrow: 2 pixels, it is narrow to avoid distraction in \fB\-ycrop\fR mode. .TP \fB\-nobell\fR Disable bell. .TP \fB\-rawlocal\fR Prefer raw encoding for localhost, default is no, i.e. assumes you have a SSH tunnel instead. .TP \fB\-notty\fR Try to avoid using the terminal for interactive responses: use windows for messages and prompting instead. Messages will also be printed to terminal. .TP \fB\-sendclipboard\fR Send the X CLIPBOARD selection (i.e. Ctrl+C, Ctrl+V) instead of the X PRIMARY selection (mouse select and middle button paste.) .TP \fB\-sendalways\fR Whenever the mouse enters the VNC viewer main window, send the selection to the VNC server even if it has not changed. This is like the Xt resource translation SelectionToVNC(always) .TP \fB\-recvtext\fR str When cut text is received from the VNC server, ssvncviewer will set both the X PRIMARY and the X CLIPBOARD local selections. To control which is set, specify 'str' as 'primary', 'clipboard', or 'both' (the default.) .TP \fB\-graball\fR Grab the entire X server when in fullscreen mode, needed by some old window managers like fvwm2. .TP \fB\-popupfix\fR Warp the popup back to the pointer position, needed by some old window managers like fvwm2. .TP \fB\-grabkbd\fR Grab the X keyboard when in fullscreen mode, needed by some window managers. Same as \fB\-grabkeyboard\fR. \fB\-grabkbd\fR is the default, use \fB\-nograbkbd\fR to disable. .TP \fB\-bs\fR, \fB\-nobs\fR Whether or not to use X server Backingstore for the main viewer window. The default is to not, mainly because most Linux, etc, systems X servers disable *all* Backingstore by default. To re\fB\-enable\fR it put Option "Backingstore" in the Device section of /etc/X11/xorg.conf. In \fB\-bs\fR mode with no X server backingstore, whenever an area of the screen is re\fB\-exposed\fR it must go out to the VNC server to retrieve the pixels. This is too slow. In \fB\-nobs\fR mode, memory is allocated by the viewer to provide its own backing of the main viewer window. This actually makes some activities faster (changes in large regions) but can appear to "flash" too much. .TP \fB\-noshm\fR Disable use of MIT shared memory extension (not recommended) .TP \fB\-termchat\fR Do the UltraVNC chat in the terminal vncviewer is in instead of in an independent window. .TP \fB\-unixpw\fR \fIstr\fR Useful for logging into x11vnc in \fB\-unixpw\fR mode. "str" is a string that allows many ways to enter the Unix Username and Unix Password. These characters: username, newline, password, newline are sent to the VNC server after any VNC authentication has taken place. Under x11vnc they are used for the \fB\-unixpw\fR login. Other VNC servers could do something similar. You can also indicate "str" via the environment variable SSVNC_UNIXPW. Note that the Escape key is actually sent first to tell x11vnc to not echo the Unix Username back to the VNC viewer. Set SSVNC_UNIXPW_NOESC=1 to override this. If str is ".", then you are prompted at the command line for the username and password in the normal way. If str is "-" the stdin is read via getpass(3) for username@password. Otherwise if str is a file, it is opened and the first line read is taken as the Unix username and the 2nd as the password. If str prefixed by "rm:" the file is removed after reading. Otherwise, if str has a "@" character, it is taken as username@password. Otherwise, the program exits with an error. Got all that? .TP \fB-repeater\fR \fIstr\fR This is for use with UltraVNC repeater proxy described here: http://www.uvnc.com/addons/repeater.html. The "str" is the ID string to be sent to the repeater. E.g. ID:1234 It can also be the hostname and port or display of the VNC server, e.g. 12.34.56.78:0 or snoopy.com:1. Note that when using -repeater, the host:dpy on the cmdline is the repeater server, NOT the VNC server. The repeater will connect you. Example: vncviewer ... -repeater ID:3333 repeat.host:5900 Example: vncviewer ... -repeater vhost:0 repeat.host:5900 Use, e.g., '-repeater SCIII=ID:3210' if the repeater is a Single Click III (SSL) repeater (repeater_SSL.exe) and you are passing the SSL part of the connection through stunnel, socat, etc. This way the magic UltraVNC string 'testB' needed to work with the repeater is sent to it. .TP \fB-rfbversion\fR \fIstr\fR Set the advertised RFB version. E.g.: -rfbversion 3.6 For some servers, e.g. UltraVNC this needs to be done. .TP \fB-ultradsm\fR UltraVNC has symmetric private encryption DSM plugins. See http://www.uvnc.com/features/encryption.html. It is assumed you are using a unix program (e.g. our ultravnc_dsm_helper) to encrypt and decrypt the UltraVNC DSM stream. IN ADDITION TO THAT supply -ultradsm to tell THIS viewer to modify the RFB data sent so as to work with the UltraVNC Server. For some reason, each RFB msg type must be sent twice under DSM. .TP \fB\-mslogon\fR \fIuser\fR Use Windows MS Logon to an UltraVNC server. Supply the username or "1" to be prompted. The default is to autodetect the UltraVNC MS Logon server and prompt for the username and password. IMPORTANT NOTE: The UltraVNC MS-Logon Diffie-Hellman exchange is very weak and can be brute forced to recover your username and password in a few seconds of CPU time. To be safe, be sure to use an additional encrypted tunnel (e.g. SSL or SSH) for the entire VNC session. .TP \fB\-chatonly\fR Try to be a client that only does UltraVNC text chat. This mode is used by x11vnc to present a chat window on the physical X11 console (i.e. to chat with the person at the display). .TP \fB-env\fR \fIVAR=VALUE\fR To save writing a shell script to set environment variables, specify as many as you need on the command line. For example, -env SSVNC_MULTIPLE_LISTEN=MAX:5 -env EDITOR=vi .TP \fB\-noipv6\fR Disable all IPv6 sockets. Same as VNCVIEWER_NO_IPV6=1. .TP \fB\-noipv4\fR Disable all IPv4 sockets. Same as VNCVIEWER_NO_IPV4=1. .TP \fB\-printres\fR Print out the Ssvnc X resources (appdefaults) and then exit. You can save them to a file and customize them (e.g. the keybindings and Popup menu) Then point to the file via XENVIRONMENT or XAPPLRESDIR. .TP \fB\-pipeline\fR Like TurboVNC, request the next framebuffer update as soon as possible instead of waiting until the end of the current framebuffer update coming in. Helps 'pipeline' the updates. This is currently the default, use \fB-nopipeline\fR to disable. .TP \fB\-appshare\fR Enable features for use with x11vnc's \fB\-appshare\fR mode where instead of sharing the full desktop only the application's windows are shared. Viewer multilisten mode is used to create the multiple windows: \fB\-multilisten\fR is implied. See 'x11vnc \fB\-appshare\fR \fB\-help\fR' more information on the mode. Features enabled in the viewer under \fB\-appshare\fR are: Minimum extra text in the title, auto \fB\-ycrop\fR is disabled, x11vnc \fB\-remote_prefix\fR X11VNC_APPSHARE_CMD: message channel, x11vnc initial window position hints. See also Escape Keys below for additional key and mouse bindings. .TP \fB\-escape \fR\fIstr\fR This sets the 'Escape Keys' modifier sequence and enables escape keys mode. When the modifier keys escape sequence is held down, the next keystroke is interpreted locally to perform a special action instead of being sent to the remote VNC server. Use '\fB\-escape\fR default' for the default modifier sequence. (Unix: Alt_L,Super_L and MacOSX: Control_L,Meta_L) Here are the 'Escape Keys: Help+Set' instructions from the Popup: Escape Keys: Enter a comma separated list of modifier keys to be the 'escape sequence'. When these keys are held down, the next keystroke is interpreted locally to invoke a special action instead of being sent to the remote VNC server. In other words, a set of 'Hot Keys'. Here is the list of local key mappings to special actions: r: refresh desktop b: toggle bell c: toggle full-color f: file transfer x: x11cursor z: toggle Tight/ZRLE l: full screen g: graball e: escape keys dialog s: scale dialog +: scale up (=) -: scale down (_) t: text chat a: alphablend cursor V: toggle viewonly Q: quit viewer 123456: UltraVNC scale 1/n Arrow keys: pan the viewport about 10% for each keypress. PageUp/PageDown: pan the viewport by a screenful vertically. Home/End: pan the viewport by a screenful horizontally. KeyPad Arrows: pan the viewport by 1 pixel for each keypress. Dragging the Mouse with Button1 pressed also pans the viewport. Clicking Mouse Button3 brings up the Popup Menu. The above mappings are \fBalways\fR active in ViewOnly mode, unless you set the Escape Keys value to 'never'. x11vnc -appshare hot-keys: x11vnc has a simple application sharing mode that enables the viewer-side to move, resize, or raise the remote toplevel windows. To enable it, hold down Shift + the Escape Keys and press these: Arrow keys: move the remote window around in its desktop. PageUp/PageDn/Home/End: resize the remote window. +/-: raise or lower the remote window. M or Button1 move win to local position; D or Button3: delete remote win. If the Escape Keys value below is set to 'default' then a default list of of modifier keys is used. For Unix it is: Alt_L,Super_L and for MacOSX it is Control_L,Meta_L. Note: the Super_L key usually has a Windows(TM) Flag on it. Also note the _L and _R mean the key is on the LEFT or RIGHT side of the keyboard. On Unix the default is Alt and Windows keys on Left side of keyboard. On MacOSX the default is Control and Command keys on Left side of keyboard. Example: Press and hold the Alt and Windows keys on the LEFT side of the keyboard and then press 'c' to toggle the full-color state. Or press 't' to toggle the ultravnc Text Chat window, etc. To use something besides the default, supply a comma separated list (or a single one) from: Shift_L Shift_R Control_L Control_R Alt_L Alt_R Meta_L Meta_R Super_L Super_R Hyper_L Hyper_R or Mode_switch. .TP \fB New Popup actions:\fR ViewOnly: ~ -viewonly Disable Bell: ~ -nobell Cursor Shape: ~ -nocursorshape X11 Cursor: ~ -x11cursor Cursor Alphablend: ~ -alpha Toggle Tight/Hextile: ~ -encodings hextile...

Send Clipboard not Primary ~ -sendclipboard Send Selection Every time ~ -sendalways .SH ENCODINGS The server supplies information in whatever format is desired by the client, in order to make the client as easy as possible to implement. If the client represents itself as able to use multiple formats, the server will choose one. .I Pixel format refers to the representation of an individual pixel. The most common formats are 24 and 16 bit "true\-color" values, and 8\-bit "color map" representations, where an arbitrary map converts the color number to RGB values. .I Encoding refers to how a rectangle of pixels are sent (all pixel information in VNC is sent as rectangles). All rectangles come with a header giving the location and size of the rectangle and an encoding type used by the data which follows. These types are listed below. .TP .B Raw The raw encoding simply sends width*height pixel values. All clients are required to support this encoding type. Raw is also the fastest when the server and viewer are on the same machine, as the connection speed is essentially infinite and raw encoding minimizes processing time. .TP .B CopyRect The Copy Rectangle encoding is efficient when something is being moved; the only data sent is the location of a rectangle from which data should be copied to the current location. Copyrect could also be used to efficiently transmit a repeated pattern. .TP .B RRE The Rise\-and\-Run\-length\-Encoding is basically a 2D version of run\-length encoding (RLE). In this encoding, a sequence of identical pixels are compressed to a single value and repeat count. In VNC, this is implemented with a background color, and then specifications of an arbitrary number of subrectangles and color for each. This is an efficient encoding for large blocks of constant color. .TP .B CoRRE This is a minor variation on RRE, using a maximum of 255x255 pixel rectangles. This allows for single\-byte values to be used, reducing packet size. This is in general more efficient, because the savings from sending 1\-byte values generally outweighs the losses from the (relatively rare) cases where very large regions are painted the same color. .TP .B Hextile Here, rectangles are split up in to 16x16 tiles, which are sent in a predetermined order. The data within the tiles is sent either raw or as a variant on RRE. Hextile encoding is usually the best choice for using in high\-speed network environments (e.g. Ethernet local\-area networks). .TP .B Zlib Zlib is a very simple encoding that uses zlib library to compress raw pixel data. This encoding achieves good compression, but consumes a lot of CPU time. Support for this encoding is provided for compatibility with VNC servers that might not understand Tight encoding which is more efficient than Zlib in nearly all real\-life situations. .TP .B Tight Like Zlib encoding, Tight encoding uses zlib library to compress the pixel data, but it pre\-processes data to maximize compression ratios, and to minimize CPU usage on compression. Also, JPEG compression may be used to encode color\-rich screen areas (see the description of \-quality and \-nojpeg options above). Tight encoding is usually the best choice for low\-bandwidth network environments (e.g. slow modem connections). .TP .B ZRLE The SSVNC viewer has ported the RealVNC (www.realvnc.com) ZRLE encoding to the unix tightvnc viewer. .TP .B ZYWRLE The SSVNC viewer has ported the Hitachi lossy wavelet based ZRLE encoding from http://mobile.hitachi-system.co.jp/publications/ZYWRLE/ to the unix tightvnc viewer. .SH RESOURCES X resources that \fBvncviewer\fR knows about, aside from the normal Xt resources, are as follows: .TP .B shareDesktop Equivalent of \fB\-shared\fR/\fB\-noshared\fR options. Default true. .TP .B viewOnly Equivalent of \fB\-viewonly\fR option. Default false. .TP .B fullScreen Equivalent of \fB\-fullscreen\fR option. Default false. .TP .B grabKeyboard Grab keyboard in full-screen mode. This can help to solve problems with losing keyboard focus. Default false. .TP .B raiseOnBeep Equivalent of \fB\-noraiseonbeep\fR option, when set to false. Default true. .TP .B passwordFile Equivalent of \fB\-passwd\fR option. .TP .B userLogin Equivalent of \fB\-user\fR option. .TP .B passwordDialog Whether to use a dialog box to get the password (true) or get it from the tty (false). Irrelevant if \fBpasswordFile\fR is set. Default false. .TP .B encodings Equivalent of \fB\-encodings\fR option. .TP .B compressLevel Equivalent of \fB\-compresslevel\fR option (TightVNC\-specific). .TP .B qualityLevel Equivalent of \fB\-quality\fR option (TightVNC\-specific). .TP .B enableJPEG Equivalent of \fB\-nojpeg\fR option, when set to false. Default true. .TP .B useRemoteCursor Equivalent of \fB\-nocursorshape\fR option, when set to false (TightVNC\-specific). Default true. .TP .B useBGR233 Equivalent of \fB\-bgr233\fR option. Default false. .TP .B nColours When using BGR233, try to allocate this many "exact" colors from the BGR233 color cube. When using a shared colormap, setting this resource lower leaves more colors for other X clients. Irrelevant when using truecolor. Default is 256 (i.e. all of them). .TP .B useSharedColours If the number of "exact" BGR233 colors successfully allocated is less than 256 then the rest are filled in using the "nearest" colors available. This resource says whether to only use the "exact" BGR233 colors for this purpose, or whether to use other clients' "shared" colors as well. Default true (i.e. use other clients' colors). .TP .B forceOwnCmap Equivalent of \fB\-owncmap\fR option. Default false. .TP .B forceTrueColour Equivalent of \fB\-truecolour\fR option. Default false. .TP .B requestedDepth Equivalent of \fB\-depth\fR option. .TP .B useSharedMemory Use MIT shared memory extension if on the same machine as the X server. Default true. .TP .B wmDecorationWidth, wmDecorationHeight The total width and height taken up by window manager decorations. This is used to calculate the maximum size of the VNC viewer window. Default is width 4, height 24. .TP .B bumpScrollTime, bumpScrollPixels When in full screen mode and the VNC desktop is bigger than the X display, scrolling happens whenever the mouse hits the edge of the screen. The maximum speed of scrolling is bumpScrollPixels pixels every bumpScrollTime milliseconds. The actual speed of scrolling will be slower than this, of course, depending on how fast your machine is. Default 20 pixels every 25 milliseconds. .TP .B popupButtonCount The number of buttons in the popup window. See the README file for more information on how to customize the buttons. .TP .B debug For debugging. Default false. .TP .B rawDelay, copyRectDelay For debugging, see the README file for details. Default 0 (off). .SH ENVIRONMENT When started with the \fB\-via\fR option, vncviewer reads the \fBVNC_VIA_CMD\fR environment variable, expands patterns beginning with the "%" character, and executes result as a command assuming that it would create TCP tunnel that should be used for VNC connection. If not set, this environment variable defaults to "/usr/bin/ssh -f -L %L:%H:%R %G sleep 20". The following patterns are recognized in the \fBVNC_VIA_CMD\fR (note that all the patterns %G, %H, %L and %R must be present in the command template): .TP .B %% A literal "%"; .TP .B %G gateway host name; .TP .B %H remote VNC host name, as known to the gateway; .TP .B %L local TCP port number; .TP .B %R remote TCP port number. .SH SEE ALSO \fBvncserver\fR(1), \fBx11vnc\fR(1), \fBssvnc\fR(1), \fBXvnc\fR(1), \fBvncpasswd\fR(1), \fBvncconnect\fR(1), \fBssh\fR(1), http://www.karlrunge.com/x11vnc, http://www.karlrunge.com/x11vnc/ssvnc.html .SH AUTHORS Original VNC was developed in AT&T Laboratories Cambridge.

It can connect to any VNC\-compatible server such +as \fBXvnc\fR, WinVNC, or \fBx11vnc\fR, allowing you to control desktop environment +of a different machine. + +ssvncviewer is an enhanced version of the tightvnc unix viewer that can +take advantage of features in the \fBx11vnc\fR and UltraVNC VNC servers. +See below for the description of these features. + +You can use F8 to display a pop\-up utility menu. Press F8 twice to +pass single F8 to the remote side. +.SH OPTIONS +.TP +\fB\-help\fR +Prints a short usage notice to stderr. +.TP +\fB\-listen\fR +Make the viewer listen on port 5500+\fIdisplay\fR for reverse +connections from a server. WinVNC supports reverse connections using +the "Add New Client" menu option, or the \-connect command line +option. \fBXvnc\fR requires the use of the helper program +\fBvncconnect\fR. +.TP +\fB\-via\fR \fIgateway\fR +Automatically create encrypted TCP tunnel to the \fIgateway\fR machine +before connection, connect to the \fIhost\fR through that tunnel +(TightVNC\-specific). By default, this option invokes SSH local port +forwarding, assuming that SSH client binary can be accessed as +/usr/bin/ssh. Note that when using the \fB\-via\fR option, the host +machine name should be specified as known to the gateway machine, e.g. +"localhost" denotes the \fIgateway\fR, not the machine where vncviewer +was launched. See the ENVIRONMENT section below for the information on +configuring the \fB\-via\fR option. +.TP +\fB\-shared\fR +When connecting, specify that a shared connection is requested. In +TightVNC, this is the default mode, allowing you to share the desktop +with other clients already using it. +.TP +\fB\-noshared\fR +When connecting, specify that the session may not be shared. This +would either disconnect other connected clients or refuse your +connection, depending on the server configuration. +.TP +\fB\-viewonly\fR +Disable transfer of mouse and keyboard events from the client to the +server. +.TP +\fB\-fullscreen\fR +Start in full\-screen mode. Please be aware that operating in +full\-screen mode may confuse X window managers. Typically, such +conflicts cause incorrect handling of input focus or make the viewer +window disappear mysteriously. See the grabKeyboard setting in the +RESOURCES section below for a method to solve input focus problem. +.TP +\fB\-noraiseonbeep\fR +By default, the viewer shows and raises its window on remote beep +(bell) event. This option disables such behaviour +(TightVNC\-specific). +.TP +\fB\-user\fR \fIusername\fR +User name for Unix login authentication. Default is to use current +Unix user name. If this option was given, the viewer will prefer Unix +login authentication over the standard VNC authentication. +.TP +\fB\-passwd\fR \fIpasswd\-file\fR +File from which to get the password (as generated by the +\fBvncpasswd\fR(1) program). This option affects only the standard VNC +authentication. +.TP +\fB\-encodings\fR \fIencoding\-list\fR +TightVNC supports several different compression methods to encode +screen updates; this option specifies a set of them to use in order of +preference. Encodings are specified separated with spaces, and must +thus be enclosed in quotes if more than one is specified. Commas may be used to avoid spaces. +Available encodings, in default order for a remote connection, are +"copyrect tight hextile zlib corre rre raw". For a local connection +(to the same machine), the default order to try is "raw copyrect tight +hextile zlib corre rre". Raw encoding is always assumed as a last option +if no other encoding can be used for some reason. For more information +on encodings, see the section ENCODINGS below. +.TP +\fB\-bgr233\fR +Always use the BGR233 format to encode pixel data. This reduces +network traffic, but colors may be represented inaccurately. The +bgr233 format is an 8\-bit "true color" format, with 2 bits blue, 3 +bits green, and 3 bits red. +.TP +\fB\-owncmap\fR +Try to use a PseudoColor visual and a private colormap. This allows +the VNC server to control the colormap. +.TP +\fB\-truecolour\fR, \fB\-truecolor\fR +Try to use a TrueColor visual. +.TP +\fB\-depth\fR \fIdepth\fR +On an X server which supports multiple TrueColor visuals of different +depths, attempt to use the specified one (in bits per pixel); if +successful, this depth will be requested from the VNC server. +.TP +\fB\-compresslevel \fIlevel\fR +Use specified compression \fIlevel\fR (0..9) for "tight" and "zlib" +encodings (TightVNC\-specific). Level 1 uses minimum of CPU time and +achieves weak compression ratios, while level 9 offers best +compression but is slow in terms of CPU time consumption on the server +side. Use high levels with very slow network connections, and low +levels when working over high\-speed LANs. It's not recommended to use +compression level 0, reasonable choices start from the level 1. +.TP +\fB\-quality \fIlevel\fR +Use the specified JPEG quality \fIlevel\fR (0..9) for the "tight" +encoding (TightVNC\-specific). Quality level 0 denotes bad image +quality but very impressive compression ratios, while level 9 offers +very good image quality at lower compression ratios. Note that the +"tight" encoder uses JPEG to encode only those screen areas that look +suitable for lossy compression, so quality level 0 does not always +mean unacceptable image quality. +.TP +\fB\-nojpeg\fR +Disable lossy JPEG compression in Tight encoding (TightVNC\-specific). +Disabling JPEG compression is not a good idea in typical cases, as +that makes the Tight encoder less efficient. You might want to use +this option if it's absolutely necessary to achieve perfect image +quality (see also the \fB\-quality\fR option). +.TP +\fB\-nocursorshape\fR +Disable cursor shape updates, protocol extensions used to handle +remote cursor movements locally on the client side +(TightVNC\-specific). Using cursor shape updates decreases delays with +remote cursor movements, and can improve bandwidth usage dramatically. +.TP +\fB\-x11cursor\fR +Use a real X11 cursor with X-style cursor shape updates, instead of +drawing the remote cursor on the framebuffer. This option also +disables the dot cursor, and disables cursor position updates in +non-fullscreen mode. +.TP +\fB\-autopass\fR +Read a plain-text password from stdin. This option affects only the +standard VNC authentication. + +.SH Enhanced TightVNC Viewer (SSVNC) OPTIONS +.TP +Enhanced TightVNC Viewer (SSVNC) web page is located at: +.TP +http://www.karlrunge.com/x11vnc/ssvnc.html +.TP +Note: ZRLE and ZYWRLE encodings are now supported. +.TP +Note: F9 is shortcut to Toggle FullScreen mode. +.TP +Note: In -listen mode set the env var. SSVNC_MULTIPLE_LISTEN=1 +to allow more than one incoming VNC server at a time. +This is the same as -multilisten described below. Set +SSVNC_MULTIPLE_LISTEN=MAX:n to allow no more than "n" +simultaneous reverse connections. + +If the host:port is specified as "exec=command args..." +then instead of making a TCP/IP socket connection to the +remote VNC server, "command args..." is executed and the +viewer is attached to its stdio. This enables tunnelling +established via an external command, e.g. an stunnel(8) +that does not involve a listening socket. +This mode does not work for -listen reverse connections. + +If the host:port is specified as "fd=n" then it is assumed +n is an already opened file descriptor to the socket. (i.e +the parent did fork+exec) + +If the host:port contains a '/' it is interpreted as a +unix-domain socket (AF_LOCAL insead of AF_INET) +.TP +\fB\-multilisten\fR +As in -listen (reverse connection listening) except +allow more than one incoming VNC server to be connected +at a time. The default for -listen of only one at a +time tries to play it safe by not allowing anyone on +the network to put (many) desktops on your screen over +a long window of time. Use -multilisten for no limit. +.TP +\fB\-acceptpopup\fR +In \fB\-listen\fR (reverse connection listening) mode when +a reverse VNC connection comes in show a popup asking +whether to Accept or Reject the connection.

"str" can also be set by +the env. var. SSVNC_SCALE. + +If you observe mouse trail painting errors, enable +X11 Cursor mode (either via Popup or \fB\-x11cursor\fR.) + +Note that scaling is done in software and so can be +slow and requires more memory. Some speedup Tips: + +ZRLE is faster than Tight in this mode. When +scaling is first detected, the encoding will +be automatically switched to ZRLE. Use the +Popup menu if you want to go back to Tight. +Set SSVNC_PRESERVE_ENCODING=1 to disable this. + +Use a solid background on the remote side. +(e.g. manually or via x11vnc \fB\-solid\fR ...) + +If the remote server is x11vnc, try client +side caching: x11vnc \fB\-ncache\fR 10 ... +.TP +\fB\-ycrop\fR n +Only show the top n rows of the framebuffer.

Messages will also be printed to terminal. +.TP +\fB\-sendclipboard\fR +Send the X CLIPBOARD selection (i.e. Ctrl+C, +Ctrl+V) instead of the X PRIMARY selection (mouse +select and middle button paste.) +.TP +\fB\-sendalways\fR +Whenever the mouse enters the VNC viewer main +window, send the selection to the VNC server even if +it has not changed. This is like the Xt resource +translation SelectionToVNC(always) +.TP +\fB\-recvtext\fR +str When cut text is received from the VNC server, +ssvncviewer will set both the X PRIMARY and the +X CLIPBOARD local selections. To control which +is set, specify 'str' as 'primary', 'clipboard', +or 'both' (the default.) +.TP +\fB\-graball\fR +Grab the entire X server when in fullscreen mode, +needed by some old window managers like fvwm2. +.TP +\fB\-popupfix\fR +Warp the popup back to the pointer position, +needed by some old window managers like fvwm2. +.TP +\fB\-grabkbd\fR +Grab the X keyboard when in fullscreen mode, +needed by some window managers.

The default is to not, mainly +because most Linux, etc, systems X servers disable +*all* Backingstore by default. To re\fB\-enable\fR it put + +Option "Backingstore" + +in the Device section of /etc/X11/xorg.conf. +In \fB\-bs\fR mode with no X server backingstore, whenever an +area of the screen is re\fB\-exposed\fR it must go out to the +VNC server to retrieve the pixels. This is too slow. + +In \fB\-nobs\fR mode, memory is allocated by the viewer to +provide its own backing of the main viewer window. This +actually makes some activities faster (changes in large +regions) but can appear to "flash" too much. +.TP +\fB\-noshm\fR +Disable use of MIT shared memory extension (not recommended) +.TP +\fB\-termchat\fR +Do the UltraVNC chat in the terminal vncviewer is in +instead of in an independent window. +.TP +\fB\-unixpw\fR \fIstr\fR +Useful for logging into x11vnc in \fB\-unixpw\fR mode. "str" is a +string that allows many ways to enter the Unix Username +and Unix Password. These characters: username, newline, +password, newline are sent to the VNC server after any VNC +authentication has taken place. Under x11vnc they are +used for the \fB\-unixpw\fR login. Other VNC servers could do +something similar. + +You can also indicate "str" via the environment +variable SSVNC_UNIXPW. + +Note that the Escape key is actually sent first to tell +x11vnc to not echo the Unix Username back to the VNC +viewer. Set SSVNC_UNIXPW_NOESC=1 to override this. + +If str is ".", then you are prompted at the command line +for the username and password in the normal way. If str is +"-" the stdin is read via getpass(3) for username@password. +Otherwise if str is a file, it is opened and the first line +read is taken as the Unix username and the 2nd as the +password. If str prefixed by "rm:" the file is removed +after reading. Otherwise, if str has a "@" character, +it is taken as username@password. Otherwise, the program +exits with an error. Got all that? +.TP +\fB-repeater\fR \fIstr\fR +This is for use with UltraVNC repeater proxy described +here: http://www.uvnc.com/addons/repeater.html. The "str" +is the ID string to be sent to the repeater. E.g. ID:1234 +It can also be the hostname and port or display of the VNC +server, e.g. 12.34.56.78:0 or snoopy.com:1. Note that when +using -repeater, the host:dpy on the cmdline is the repeater +server, NOT the VNC server. The repeater will connect you. + +Example: vncviewer ... -repeater ID:3333 repeat.host:5900 + +Example: vncviewer ... -repeater vhost:0 repeat.host:5900 + +Use, e.g., '-repeater SCIII=ID:3210' if the repeater is a +Single Click III (SSL) repeater (repeater_SSL.exe) and you +are passing the SSL part of the connection through stunnel, socat, etc. +This way the magic UltraVNC string 'testB' needed to work with the +repeater is sent to it. +.TP +\fB-rfbversion\fR \fIstr\fR +Set the advertised RFB version. E.g.: -rfbversion 3.6 For some +servers, e.g. UltraVNC this needs to be done. +.TP +\fB-ultradsm\fR +UltraVNC has symmetric private encryption DSM plugins. See +http://www.uvnc.com/features/encryption.html. It is assumed +you are using a unix program (e.g. our ultravnc_dsm_helper) to +encrypt and decrypt the UltraVNC DSM stream. IN ADDITION TO +THAT supply -ultradsm to tell THIS viewer to modify the RFB +data sent so as to work with the UltraVNC Server. For some +reason, each RFB msg type must be sent twice under DSM. +.TP +\fB\-mslogon\fR \fIuser\fR +Use Windows MS Logon to an UltraVNC server. Supply the +username or "1" to be prompted. The default is to +autodetect the UltraVNC MS Logon server and prompt for +the username and password. + +IMPORTANT NOTE: The UltraVNC MS-Logon Diffie-Hellman +exchange is very weak and can be brute forced to recover +your username and password in a few seconds of CPU +time. To be safe, be sure to use an additional encrypted +tunnel (e.g. SSL or SSH) for the entire VNC session. +.TP +\fB\-chatonly\fR +Try to be a client that only does UltraVNC text chat. This +mode is used by x11vnc to present a chat window on the physical +X11 console (i.e. to chat with the person at the display). +.TP +\fB-env\fR \fIVAR=VALUE\fR +To save writing a shell script to set environment +variables, specify as many as you need on the command line. For example, +-env SSVNC_MULTIPLE_LISTEN=MAX:5 -env EDITOR=vi +.TP +\fB\-noipv6\fR +Disable all IPv6 sockets. Same as VNCVIEWER_NO_IPV6=1. +.TP +\fB\-noipv4\fR +Disable all IPv4 sockets. Same as VNCVIEWER_NO_IPV4=1. +.TP +\fB\-printres\fR +Print out the Ssvnc X resources (appdefaults) and +then exit. You can save them to a file and customize them (e.g. the +keybindings and Popup menu) Then point to the file via +XENVIRONMENT or XAPPLRESDIR. +.TP +\fB\-pipeline\fR +Like TurboVNC, request the next framebuffer update as soon +as possible instead of waiting until the end of the current +framebuffer update coming in. Helps 'pipeline' the updates. +This is currently the default, use \fB-nopipeline\fR to disable. +.TP +\fB\-appshare\fR +Enable features for use with x11vnc's \fB\-appshare\fR mode where +instead of sharing the full desktop only the application's +windows are shared. Viewer multilisten mode is used to +create the multiple windows: \fB\-multilisten\fR is implied. +See 'x11vnc \fB\-appshare\fR \fB\-help\fR' more information on the mode. +Features enabled in the viewer under \fB\-appshare\fR are: +Minimum extra text in the title, auto \fB\-ycrop\fR is disabled, +x11vnc \fB\-remote_prefix\fR X11VNC_APPSHARE_CMD: message channel, +x11vnc initial window position hints. See also Escape Keys +below for additional key and mouse bindings. +.TP +\fB\-escape \fR\fIstr\fR +This sets the 'Escape Keys' modifier sequence and enables +escape keys mode. When the modifier keys escape sequence +is held down, the next keystroke is interpreted locally +to perform a special action instead of being sent to the +remote VNC server. + +Use '\fB\-escape\fR default' for the default modifier sequence. +(Unix: Alt_L,Super_L and MacOSX: Control_L,Meta_L) + +Here are the 'Escape Keys: Help+Set' instructions from the Popup: + +Escape Keys: Enter a comma separated list of modifier keys to be the 'escape +sequence'. When these keys are held down, the next keystroke is +interpreted locally to invoke a special action instead of being sent to +the remote VNC server. In other words, a set of 'Hot Keys'. + +Here is the list of local key mappings to special actions: + +r: refresh desktop b: toggle bell c: toggle full-color + +f: file transfer x: x11cursor z: toggle Tight/ZRLE + +l: full screen g: graball e: escape keys dialog + +s: scale dialog +: scale up (=) -: scale down (_) + +t: text chat a: alphablend cursor + +V: toggle viewonly Q: quit viewer 123456: UltraVNC scale 1/n + +Arrow keys: pan the viewport about 10% for each keypress. + +PageUp/PageDown: pan the viewport by a screenful vertically. + +Home/End: pan the viewport by a screenful horizontally. + +KeyPad Arrows: pan the viewport by 1 pixel for each keypress. + +Dragging the Mouse with Button1 pressed also pans the viewport. + +Clicking Mouse Button3 brings up the Popup Menu. + +The above mappings are \fBalways\fR active in ViewOnly mode, unless you set +the Escape Keys value to 'never'. + +x11vnc -appshare hot-keys: x11vnc has a simple application sharing mode +that enables the viewer-side to move, resize, or raise the remote toplevel +windows. To enable it, hold down Shift + the Escape Keys and press these: + +Arrow keys: move the remote window around in its desktop. + +PageUp/PageDn/Home/End: resize the remote window. + ++/-: raise or lower the remote window. + +M or Button1 move win to local position; D or Button3: delete remote win. + +If the Escape Keys value below is set to 'default' then a default list of +of modifier keys is used. For Unix it is: Alt_L,Super_L and for MacOSX it +is Control_L,Meta_L. Note: the Super_L key usually has a Windows(TM) Flag +on it. Also note the _L and _R mean the key is on the LEFT or RIGHT side +of the keyboard. + +On Unix the default is Alt and Windows keys on Left side of keyboard. +On MacOSX the default is Control and Command keys on Left side of keyboard. + +Example: Press and hold the Alt and Windows keys on the LEFT side of the +keyboard and then press 'c' to toggle the full-color state. Or press 't' +to toggle the ultravnc Text Chat window, etc. + +To use something besides the default, supply a comma separated list (or a +single one) from: Shift_L Shift_R Control_L Control_R Alt_L Alt_R Meta_L +Meta_R Super_L Super_R Hyper_L Hyper_R or Mode_switch. +.TP +\fB New Popup actions:\fR + + ViewOnly: ~ -viewonly + Disable Bell: ~ -nobell + Cursor Shape: ~ -nocursorshape + X11 Cursor: ~ -x11cursor + Cursor Alphablend: ~ -alpha + Toggle Tight/Hextile: ~ -encodings hextile... + Toggle Tight/ZRLE: ~ -encodings zrle... + Toggle ZRLE/ZYWRLE: ~ -encodings zywrle... + Quality Level ~ -quality (both Tight and ZYWRLE) + Compress Level ~ -compresslevel + Disable JPEG: ~ -nojpeg (Tight) + Pipeline Updates ~ -pipeline + + Full Color as many colors as local screen allows. + Grey scale (16 & 8-bpp) ~ -grey, for low colors 16/8bpp modes only. + 16 bit color (BGR565) ~ -16bpp / -bgr565 + 8 bit color (BGR233) ~ -bgr233 + 256 colors ~ -bgr233 default # of colors. + 64 colors ~ -bgr222 / -use64 + 8 colors ~ -bgr111 / -use8 + Scale Viewer ~ -scale + Escape Keys: Toggle ~ -escape + Escape Keys: Help+Set ~ -escape + Set Y Crop (y-max) ~ -ycrop + Set Scrollbar Width ~ -sbwidth + XGrabServer ~ -graball + + UltraVNC Extensions: + + Set 1/n Server Scale Ultravnc ext.

The most common +formats are 24 and 16 bit "true\-color" values, and 8\-bit "color map" +representations, where an arbitrary map converts the color number to +RGB values. + +.I Encoding +refers to how a rectangle of pixels are sent (all pixel information in +VNC is sent as rectangles). All rectangles come with a header giving +the location and size of the rectangle and an encoding type used by +the data which follows. These types are listed below. +.TP +.B Raw +The raw encoding simply sends width*height pixel values. All clients +are required to support this encoding type. Raw is also the fastest +when the server and viewer are on the same machine, as the connection +speed is essentially infinite and raw encoding minimizes processing +time. +.TP +.B CopyRect +The Copy Rectangle encoding is efficient when something is being +moved; the only data sent is the location of a rectangle from which +data should be copied to the current location. Copyrect could also be +used to efficiently transmit a repeated pattern. +.TP +.B RRE +The Rise\-and\-Run\-length\-Encoding is basically a 2D version of +run\-length encoding (RLE). In this encoding, a sequence of identical +pixels are compressed to a single value and repeat count. In VNC, this +is implemented with a background color, and then specifications of an +arbitrary number of subrectangles and color for each. This is an +efficient encoding for large blocks of constant color. +.TP +.B CoRRE +This is a minor variation on RRE, using a maximum of 255x255 pixel +rectangles. This allows for single\-byte values to be used, reducing +packet size. This is in general more efficient, because the savings +from sending 1\-byte values generally outweighs the losses from the +(relatively rare) cases where very large regions are painted the same +color. +.TP +.B Hextile +Here, rectangles are split up in to 16x16 tiles, which are sent in a +predetermined order. The data within the tiles is sent either raw or +as a variant on RRE. Hextile encoding is usually the best choice for +using in high\-speed network environments (e.g. Ethernet local\-area +networks). +.TP +.B Zlib +Zlib is a very simple encoding that uses zlib library to compress raw +pixel data. This encoding achieves good compression, but consumes a +lot of CPU time. Support for this encoding is provided for +compatibility with VNC servers that might not understand Tight +encoding which is more efficient than Zlib in nearly all real\-life +situations. +.TP +.B Tight +Like Zlib encoding, Tight encoding uses zlib library to compress the +pixel data, but it pre\-processes data to maximize compression ratios, +and to minimize CPU usage on compression. Also, JPEG compression may +be used to encode color\-rich screen areas (see the description of +\-quality and \-nojpeg options above). Tight encoding is usually the +best choice for low\-bandwidth network environments (e.g. slow modem +connections). +.TP +.B ZRLE +The SSVNC viewer has ported the RealVNC (www.realvnc.com) ZRLE encoding +to the unix tightvnc viewer. +.TP +.B ZYWRLE +The SSVNC viewer has ported the Hitachi lossy wavelet based ZRLE +encoding from http://mobile.hitachi-system.co.jp/publications/ZYWRLE/ +to the unix tightvnc viewer. +.SH RESOURCES +X resources that \fBvncviewer\fR knows about, aside from the +normal Xt resources, are as follows: +.TP +.B shareDesktop +Equivalent of \fB\-shared\fR/\fB\-noshared\fR options.

Use the +Popup menu if you want to go back to Tight. +Set SSVNC_PRESERVE_ENCODING=1 to disable this. + +Use a solid background on the remote side. +(e.g. manually or via x11vnc \fB\-solid\fR ...) + +If the remote server is x11vnc, try client +side caching: x11vnc \fB\-ncache\fR 10 ... +.TP +\fB\-ycrop\fR n +Only show the top n rows of the framebuffer. For +use with x11vnc \fB\-ncache\fR client caching option +to help "hide" the pixel cache region. +Use a negative value (e.g. \fB\-1\fR) for autodetection. +Autodetection will always take place if the remote +fb height is more than 2 times the width. +.TP +\fB\-sbwidth\fR n +Scrollbar width for x11vnc \fB\-ncache\fR mode (\fB\-ycrop\fR), +default is very narrow: 2 pixels, it is narrow to +avoid distraction in \fB\-ycrop\fR mode. +.TP +\fB\-nobell\fR +Disable bell. +.TP +\fB\-rawlocal\fR +Prefer raw encoding for localhost, default is +no, i.e. assumes you have a SSH tunnel instead. +.TP +\fB\-notty\fR +Try to avoid using the terminal for interactive +responses: use windows for messages and prompting +instead. Messages will also be printed to terminal. +.TP +\fB\-sendclipboard\fR +Send the X CLIPBOARD selection (i.e. Ctrl+C, +Ctrl+V) instead of the X PRIMARY selection (mouse +select and middle button paste.) +.TP +\fB\-sendalways\fR +Whenever the mouse enters the VNC viewer main +window, send the selection to the VNC server even if +it has not changed. This is like the Xt resource +translation SelectionToVNC(always) +.TP +\fB\-recvtext\fR +str When cut text is received from the VNC server, +ssvncviewer will set both the X PRIMARY and the +X CLIPBOARD local selections. To control which +is set, specify 'str' as 'primary', 'clipboard', +or 'both' (the default.) +.TP +\fB\-graball\fR +Grab the entire X server when in fullscreen mode, +needed by some old window managers like fvwm2. +.TP +\fB\-popupfix\fR +Warp the popup back to the pointer position, +needed by some old window managers like fvwm2. +.TP +\fB\-grabkbd\fR +Grab the X keyboard when in fullscreen mode, +needed by some window managers. Same as \fB\-grabkeyboard\fR. +\fB\-grabkbd\fR is the default, use \fB\-nograbkbd\fR to disable. +.TP +\fB\-bs\fR, \fB\-nobs\fR +Whether or not to use X server Backingstore for the +main viewer window. The default is to not, mainly +because most Linux, etc, systems X servers disable +*all* Backingstore by default. To re\fB\-enable\fR it put + +Option "Backingstore" + +in the Device section of /etc/X11/xorg.conf. +In \fB\-bs\fR mode with no X server backingstore, whenever an +area of the screen is re\fB\-exposed\fR it must go out to the +VNC server to retrieve the pixels. This is too slow. + +In \fB\-nobs\fR mode, memory is allocated by the viewer to +provide its own backing of the main viewer window. This +actually makes some activities faster (changes in large +regions) but can appear to "flash" too much. +.TP +\fB\-noshm\fR +Disable use of MIT shared memory extension (not recommended) +.TP +\fB\-termchat\fR +Do the UltraVNC chat in the terminal vncviewer is in +instead of in an independent window. +.TP +\fB\-unixpw\fR \fIstr\fR +Useful for logging into x11vnc in \fB\-unixpw\fR mode. "str" is a +string that allows many ways to enter the Unix Username +and Unix Password. These characters: username, newline, +password, newline are sent to the VNC server after any VNC +authentication has taken place. Under x11vnc they are +used for the \fB\-unixpw\fR login. Other VNC servers could do +something similar. + +You can also indicate "str" via the environment +variable SSVNC_UNIXPW. + +Note that the Escape key is actually sent first to tell +x11vnc to not echo the Unix Username back to the VNC +viewer. Set SSVNC_UNIXPW_NOESC=1 to override this. + +If str is ".", then you are prompted at the command line +for the username and password in the normal way. If str is +"-" the stdin is read via getpass(3) for username@password. +Otherwise if str is a file, it is opened and the first line +read is taken as the Unix username and the 2nd as the +password. If str prefixed by "rm:" the file is removed +after reading. Otherwise, if str has a "@" character, +it is taken as username@password. Otherwise, the program +exits with an error. Got all that? +.TP +\fB-repeater\fR \fIstr\fR +This is for use with UltraVNC repeater proxy described +here: http://www.uvnc.com/addons/repeater.html. The "str" +is the ID string to be sent to the repeater. E.g. ID:1234 +It can also be the hostname and port or display of the VNC +server, e.g. 12.34.56.78:0 or snoopy.com:1. Note that when +using -repeater, the host:dpy on the cmdline is the repeater +server, NOT the VNC server. The repeater will connect you. + +Example: vncviewer ... -repeater ID:3333 repeat.host:5900 + +Example: vncviewer ... -repeater vhost:0 repeat.host:5900 + +Use, e.g., '-repeater SCIII=ID:3210' if the repeater is a +Single Click III (SSL) repeater (repeater_SSL.exe) and you +are passing the SSL part of the connection through stunnel, socat, etc. +This way the magic UltraVNC string 'testB' needed to work with the +repeater is sent to it. +.TP +\fB-rfbversion\fR \fIstr\fR +Set the advertised RFB version. E.g.: -rfbversion 3.6 For some +servers, e.g. UltraVNC this needs to be done. +.TP +\fB-ultradsm\fR +UltraVNC has symmetric private encryption DSM plugins. See +http://www.uvnc.com/features/encryption.html. It is assumed +you are using a unix program (e.g. our ultravnc_dsm_helper) to +encrypt and decrypt the UltraVNC DSM stream. IN ADDITION TO +THAT supply -ultradsm to tell THIS viewer to modify the RFB +data sent so as to work with the UltraVNC Server. For some +reason, each RFB msg type must be sent twice under DSM. +.TP +\fB\-mslogon\fR \fIuser\fR +Use Windows MS Logon to an UltraVNC server. Supply the +username or "1" to be prompted. The default is to +autodetect the UltraVNC MS Logon server and prompt for +the username and password. + +IMPORTANT NOTE: The UltraVNC MS-Logon Diffie-Hellman +exchange is very weak and can be brute forced to recover +your username and password in a few seconds of CPU +time. To be safe, be sure to use an additional encrypted +tunnel (e.g. SSL or SSH) for the entire VNC session. +.TP +\fB\-chatonly\fR +Try to be a client that only does UltraVNC text chat. This +mode is used by x11vnc to present a chat window on the physical +X11 console (i.e. to chat with the person at the display). +.TP +\fB-env\fR \fIVAR=VALUE\fR +To save writing a shell script to set environment +variables, specify as many as you need on the command line. For example, +-env SSVNC_MULTIPLE_LISTEN=MAX:5 -env EDITOR=vi +.TP +\fB\-noipv6\fR +Disable all IPv6 sockets. Same as VNCVIEWER_NO_IPV6=1. +.TP +\fB\-noipv4\fR +Disable all IPv4 sockets. Same as VNCVIEWER_NO_IPV4=1. +.TP +\fB\-printres\fR +Print out the Ssvnc X resources (appdefaults) and +then exit. You can save them to a file and customize them (e.g. the +keybindings and Popup menu) Then point to the file via +XENVIRONMENT or XAPPLRESDIR. +.TP +\fB\-pipeline\fR +Like TurboVNC, request the next framebuffer update as soon +as possible instead of waiting until the end of the current +framebuffer update coming in. Helps 'pipeline' the updates. +This is currently the default, use \fB-nopipeline\fR to disable. +.TP +\fB\-appshare\fR +Enable features for use with x11vnc's \fB\-appshare\fR mode where +instead of sharing the full desktop only the application's +windows are shared. Viewer multilisten mode is used to +create the multiple windows: \fB\-multilisten\fR is implied. +See 'x11vnc \fB\-appshare\fR \fB\-help\fR' more information on the mode. +Features enabled in the viewer under \fB\-appshare\fR are: +Minimum extra text in the title, auto \fB\-ycrop\fR is disabled, +x11vnc \fB\-remote_prefix\fR X11VNC_APPSHARE_CMD: message channel, +x11vnc initial window position hints. See also Escape Keys +below for additional key and mouse bindings. +.TP +\fB\-escape \fR\fIstr\fR +This sets the 'Escape Keys' modifier sequence and enables +escape keys mode. When the modifier keys escape sequence +is held down, the next keystroke is interpreted locally +to perform a special action instead of being sent to the +remote VNC server. + +Use '\fB\-escape\fR default' for the default modifier sequence. +(Unix: Alt_L,Super_L and MacOSX: Control_L,Meta_L) + +Here are the 'Escape Keys: Help+Set' instructions from the Popup: + +Escape Keys: Enter a comma separated list of modifier keys to be the 'escape +sequence'. When these keys are held down, the next keystroke is +interpreted locally to invoke a special action instead of being sent to +the remote VNC server. In other words, a set of 'Hot Keys'. + +Here is the list of local key mappings to special actions: + +r: refresh desktop b: toggle bell c: toggle full-color + +f: file transfer x: x11cursor z: toggle Tight/ZRLE + +l: full screen g: graball e: escape keys dialog + +s: scale dialog +: scale up (=) -: scale down (_) + +t: text chat a: alphablend cursor + +V: toggle viewonly Q: quit viewer 123456: UltraVNC scale 1/n + +Arrow keys: pan the viewport about 10% for each keypress. + +PageUp/PageDown: pan the viewport by a screenful vertically. + +Home/End: pan the viewport by a screenful horizontally. + +KeyPad Arrows: pan the viewport by 1 pixel for each keypress. + +Dragging the Mouse with Button1 pressed also pans the viewport. + +Clicking Mouse Button3 brings up the Popup Menu. + +The above mappings are \fBalways\fR active in ViewOnly mode, unless you set +the Escape Keys value to 'never'. + +x11vnc -appshare hot-keys: x11vnc has a simple application sharing mode +that enables the viewer-side to move, resize, or raise the remote toplevel +windows. To enable it, hold down Shift + the Escape Keys and press these: + +Arrow keys: move the remote window around in its desktop. + +PageUp/PageDn/Home/End: resize the remote window. + ++/-: raise or lower the remote window. + +M or Button1 move win to local position; D or Button3: delete remote win. + +If the Escape Keys value below is set to 'default' then a default list of +of modifier keys is used. For Unix it is: Alt_L,Super_L and for MacOSX it +is Control_L,Meta_L. Note: the Super_L key usually has a Windows(TM) Flag +on it. Also note the _L and _R mean the key is on the LEFT or RIGHT side +of the keyboard. + +On Unix the default is Alt and Windows keys on Left side of keyboard. +On MacOSX the default is Control and Command keys on Left side of keyboard. + +Example: Press and hold the Alt and Windows keys on the LEFT side of the +keyboard and then press 'c' to toggle the full-color state. Or press 't' +to toggle the ultravnc Text Chat window, etc. + +To use something besides the default, supply a comma separated list (or a +single one) from: Shift_L Shift_R Control_L Control_R Alt_L Alt_R Meta_L +Meta_R Super_L Super_R Hyper_L Hyper_R or Mode_switch. +.TP +\fB New Popup actions:\fR + + ViewOnly: ~ -viewonly + Disable Bell: ~ -nobell + Cursor Shape: ~ -nocursorshape + X11 Cursor: ~ -x11cursor + Cursor Alphablend: ~ -alpha + Toggle Tight/Hextile: ~ -encodings hextile... + Toggle Tight/ZRLE: ~ -encodings zrle... + Toggle ZRLE/ZYWRLE: ~ -encodings zywrle... + Quality Level ~ -quality (both Tight and ZYWRLE) + Compress Level ~ -compresslevel + Disable JPEG: ~ -nojpeg (Tight) + Pipeline Updates ~ -pipeline + + Full Color as many colors as local screen allows. + Grey scale (16 & 8-bpp) ~ -grey, for low colors 16/8bpp modes only. + 16 bit color (BGR565) ~ -16bpp / -bgr565 + 8 bit color (BGR233) ~ -bgr233 + 256 colors ~ -bgr233 default # of colors. + 64 colors ~ -bgr222 / -use64 + 8 colors ~ -bgr111 / -use8 + Scale Viewer ~ -scale + Escape Keys: Toggle ~ -escape + Escape Keys: Help+Set ~ -escape + Set Y Crop (y-max) ~ -ycrop + Set Scrollbar Width ~ -sbwidth + XGrabServer ~ -graball + + UltraVNC Extensions: + + Set 1/n Server Scale Ultravnc ext.

Runge grants anyone the # right to use this work for any purpose, without any conditions, unless # such conditions are required by law. # INTRO: ------ This is a "patch" to make x11vnc/libvncserver work with TurboVNC: http://www.virtualgl.org/About/TurboVNC http://www.karlrunge.com/x11vnc/faq.html#faq-turbovnc It is very experimental/kludgy. Not all TurboVNC features may be enabled. We are currently evaluating whether TurboVNC support should be officially put into x11vnc/libvncserver. TurboVNC is an optimized VNC for fast refresh rates on fast networks. It does pretty well on good broadband as well. But it is not as fast as regular TightVNC on slow links. TURBOJPEG: --------- TurboVNC uses the TurboJPEG library based on a fast proprietary JPEG implementation. You will need to download it from the VirtualGL sourceforge site: http://sourceforge.net/project/showfiles.php?group_id=117509&package_id=166100 Either install it or simply unpack the .deb or .rpm file into a directory. N.B. you can unpack a .deb via 'ar x package.deb' and the extracting from the data.tar.gz file. rpm2cpio can be used to unpack .rpm's. QUICK-START: ------------ For those in a hurry: cd x11vnc-x.y.z/x11vnc/misc/turbovnc ./apply_turbovnc cd ../../.. env LDFLAGS='-L/DIR -Xlinker --rpath=/DIR' ./configure make AM_LDFLAGS='-lturbojpeg' where you replace /DIR with your directory containing libturbojpeg.so. PATCHING AND BUILDING: ---------------------- After unpacking your x11vnc-x.y.z.tar.gz tarball cd to the x11vnc-x.y.z/x11vnc/misc/turbovnc (where this README file is) and from that directory run: ./apply_turbovnc that will modify files in the libvncserver and x11vnc directories above this directory. (To undo these changes run: ./undo_turbovnc) The input sources, tight.c and turbojpeg.h are from the TurboVNC source package. After applying, go back to the top level source directory and run: env LDFLAGS='-L/path/to/turbojpeg -Xlinker --rpath=/path/to/turbojpeg' ./configure where the turbojpeg library is: /path/to/turbojpeg/libturbojpeg.so (change /path/to/turbojpeg to the directory where you installed or unpacked it.) If you are not using gnu gcc and gnu linker the options may be a little different (e.g. -R instead of -Xlinker --rpath). If you need additional ./configure options or env. var. settings, add them too. Next, run this make command: make AM_LDFLAGS='-lturbojpeg' This is a hack and may not always work, if it doesn't edit x11vnc/Makefile and add '-lturbojpeg' to the LIBS variable. This should create a binary: ./x11vnc/x11vnc that supports VirtualGL's TurboVNC. You will need a TurboVNC viewer, you can get one here: http://sourceforge.net/project/showfiles.php?group_id=117509&package_id=128130 Let us know how it goes. PERFORMANCE: ------------ Note that x11vnc has to read the display's screen pixels from the graphics card memory. This can be slow, e.g. 10 MB/sec. There is not a big need for graphics card manufacturers to optimize the read rate; the write rate is the one they optimize greatly. http://www.karlrunge.com/x11vnc/#limitations If you run x11vnc and see lines like this: 28/02/2009 00:52:07 Autoprobing selected port 5900 28/02/2009 00:52:07 fb read rate: 10 MB/sec 28/02/2009 00:52:07 screen setup finished. you have a typical slow one. Whereas if you see this: 28/02/2009 00:54:46 Autoprobing selected port 5900 28/02/2009 00:54:46 fb read rate: 321 MB/sec 28/02/2009 00:54:46 fast read: reset wait ms to: 10 28/02/2009 00:54:46 fast read: reset defer ms to: 10 28/02/2009 00:54:46 screen setup finished. that is very fast. In such a situation you may want to dial down x11vnc's delay, e.g.: -wait 5 -defer 5, or even smaller to push things out more quickly. We have only seen it this fast on Linux by using the nvidia proprietary graphics drivers. The Xorg drivers are typically slow 10 MB/sec. It will also be fast if the X server is virtual: Xvfb or Xdummy since the screen pixels are stored in RAM: http://www.karlrunge.com/x11vnc/faq.html#faq-xvfb And it will be fast if the ShadowFB xorg.conf option is enabled (if the card supports it.) The point we are trying to make is that even though TurboVNC uses a wicked fast JPEG implementation, and cuts out overhead in its attempt to pump out as many frames per second as it can, if it is slow for x11vnc to read the screen pixels in the first place then you might not even notice the TurboVNC speedup. So TurboVNC+x11vnc will be faster than TightVNC+x11vnc, but if there is a large overhead/bottleneck from reading the graphics card framebuffer, then the speedup will be marginal. ������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������x11vnc-0.9.17/misc/turbovnc/apply_turbovnc����������������������������������������������������������0000775�0000000�0000000�00000002213�15004634506�0020523�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������#!/bin/sh # # This script has been (or is hereby) released into the public domain by # its author, Karl J.

Listen on one port for vnc servers (default 5500.) Read 250 bytes from connecting vnc client or server. Accept ID:<string> from clients and servers, connect them together once both are present. The string "RFB 000.000\n" is sent to the client (the client must understand this means send ID:... or host:port.) Also accept <host>:<port> from clients and make the connection to the vnc server immediately. Note there is no authentication or security WRT ID names or identities; it is up to the client and server to completely manage that aspect and whether to encrypt the session, etc. usage: ultravnc_repeater.pl [-r] [client_port [server_port]] Use -r to refuse new server/client connections when there is an existing server/client ID. The default is to close the previous one. To write to a log file set the env. var ULTRAVNC_REPEATER_LOGFILE. To run in a loop restarting the server if it exits set the env. var. ULTRAVNC_REPEATER_LOOP=1 or ULTRAVNC_REPEATER_LOOP=BG, the latter forks into the background. Set ULTRAVNC_REPEATER_PIDFILE to a file to store the master pid in. Set ULTRAVNC_REPEATER_NO_RFB=1 to disable sending "RFB 000.000" to the client. Then this program acts as general TCP rendezvous tool.

Similarly, the other side must send us\n" " its random salt and IV with those same lengths.\n" "\n" " The salt and key data are combined to create a session\n" " key using an md5 hash as described in EVP_BytesToKey(3).\n" "\n" " The exact call is: EVP_BytesToKey(Cipher, EVP_md5(),\n" " salt, keydata, len, 1, keystr, NULL); where salt is\n" " the random data as described above, and keydata is the\n" " shared secret key data. keystr is the resulting session\n" " key.

X11VNC_REFLECT_PASSWORD can be set to\n" " the password needed to log into the vnc host server, or\n" " to \"file:path_to_file\" to indicate a file containing\n" " the password as its first line.\n" "\n" " To set the pixel format that x11vnc requests as a VNC\n" " CLIENT set the env. vars: X11VNC_REFLECT_bitsPerSample\n" " X11VNC_REFLECT_samplesPerPixel, and\n" " X11VNC_REFLECT_bytesPerPixel; the defaults are 8, 3, 4.\n" " 2, 3, 1 would give a low color mode. See the function\n" " rfbGetClient() in libvncclient for more info.\n" "\n" " The VNC HOST mode implies -shared. Use -noshared as\n" " a subsequent cmdline option to disable sharing.\n" "\n" "-freqtab file For use with \"-rawfb video\" for TV tuner devices to\n" " specify station frequencies. Instead of using the built\n" " in ntsc-cable-us mapping of station number to frequency,\n" " use the data in file. For stations that are not\n" " numeric, e.g. SE20, they are placed above the highest\n" " numbered station in the order they are found. Example:\n" " \"-freqtab /usr/X11R6/share/xawtv/europe-west.list\"\n" " You can make your own freqtab by copying the xawtv\n" " format.\n" "\n" "-pipeinput cmd This option lets you supply an external command in\n" " \"cmd\" that x11vnc will pipe all of the user input\n" " events to in a simple format. In -pipeinput mode by\n" " default x11vnc will not process any of the user input\n" " events. If you prefix \"cmd\" with \"tee:\" it will\n" " both send them to the pipe command and process them.\n" " For a description of the format run \"-pipeinput\n" " tee:/bin/cat\". Another prefix is \"reopen\" which\n" " means to reopen pipe if it exits. Separate multiple\n" " prefixes with commas.\n" "\n" " In combination with -rawfb one might be able to\n" " do amusing things (e.g. control non-X devices).\n" " To facilitate this, if -rawfb is in effect then the\n" " value is stored in X11VNC_RAWFB_STR for the pipe command\n" " to use if it wants. Do 'env | grep X11VNC' for more.\n" "\n" " Built-in pipeinput modes (no external program required):\n" "\n" " If cmd is \"VID\" and you are using the -rawfb for a\n" " video capture device, then an internal list of keyboard\n" " mappings is used to set parameters of the video.\n" " The mappings are:\n" "\n" " \"B\" and \"b\" adjust the brightness up and down.\n" " \"H\" and \"h\" adjust the hue.\n" " \"C\" and \"c\" adjust the colour.\n" " \"N\" and \"n\" adjust the contrast.\n" " \"S\" and \"s\" adjust the size of the capture screen.\n" " \"I\" and \"i\" cycle through input channels.\n" " Up and Down arrows adjust the station (if a tuner)\n" " F1, F2, ..., F6 will switch the video capture pixel\n" " format to HI240, RGB565, RGB24, RGB32, RGB555, and\n" " GREY respectively. See -rawfb video for details.\n" "\n" " If cmd is \"CONSOLE\" or \"CONSOLEn\" where n\n" " is a Linux console number, then the linux console\n" " keystroke insertion to /dev/ttyN (see -rawfb console)\n" " is performed.\n" "\n" " If cmd begins with \"UINPUT\" then the Linux uinput\n" " module is used to insert both keystroke and mouse events\n" " to the Linux console (see -rawfb above). This usually\n" " is the /dev/input/uinput device file (you may need to\n" " create it with \"mknod /dev/input/uinput c 10 223\"\n" " and insert the module with \"modprobe uinput\".\n" "\n" " The UINPUT mode currently only does US keyboards (a\n" " scan code option may be added), and not all keysyms\n" " are supported. But it is probably more accurate than\n" " the \"CONSOLE\" method.\n" "\n" " You may want to use the options -cursor none and\n" " -nodragging in this mode.\n" "\n" " Additional tuning options may be supplied via:\n" " UINPUT:opt1,opt2,... (a comma separated list). If an\n" " option begins with \"/\" it is taken as the uinput\n" " device file.\n" " \n" " Which uinput is injected can be controlled by an option\n" " string made of the characters \"K\", \"M\", and \"B\"\n" " (see the -input option), e.g. \"KM\" allows keystroke\n" " and motion but not button clicks.\n" "\n" " A UINPUT option of the form: accel=f, or accel=fx+fy\n" " sets the mouse motion \"acceleration\". This is used\n" " to correct raw mouse relative motion into how much the\n" " application cursor moves (x11vnc has no control over,\n" " or knowledge of how the windowing application interprets\n" " the raw mouse motions). Typically the acceleration\n" " for an X display is 2 (see xset \"m\" option). \"f\"\n" " is a floating point number, e.g. 3.0. Use \"fx+fy\"\n" " if you need to supply different corrections for x and y.\n" "\n" " Note: the default acceleration is 2.0 since it seems\n" " both X and qt-embedded often (but not always) use\n" " this value.\n" "\n" " Even with a correct accel setting the mouse position\n" " will get out of sync (probably due to a mouse\n" " \"threshold\" setting where the acceleration doe not\n" " apply, set xset(1)). The option reset=N sets the\n" " number of ms (default 150) after which the cursor is\n" " attempted to be reset (by forcing the mouse to (0,\n" " 0) via small increments and then back out to (x, y)\n" " in 1 jump), This correction seems to be needed but can\n" " cause jerkiness or unexpected behavior with menus, etc.\n" " Use reset=0 to disable.\n" "\n" " If you set the env. var X11VNC_UINPUT_THRESHOLDS then\n" " the thresh=n mode will be enabled. It is currently\n" " not working well. If |dx| <= thresh and |dy| < thresh\n" " no acceleration is applied. Use \"thresh=+n\" |dx| +\n" " |dy| < thresh to be used instead (X11?)\n" "\n" " Example:\n" " -pipeinput UINPUT:accel=4.0 -cursor none\n" "\n" " If the uinput device has an absolute pointer (as opposed\n" " to a normal mouse that is a relative pointer) you can\n" " specify the option \"abs\". Note that a touchpad\n" " on a laptop is an absolute device to some degree.\n" " This (usually) avoids all the problems with mouse\n" " acceleration. If x11vnc has trouble deducing the\n" " size of the device, use \"abs=WxH\". Furthermore,\n" " if the device is a touchscreen (assumed to have an\n" " absolute pointer) use \"touch\" or \"touch=WxH\".\n" " For touchscreens, when a mouse button is pressed,\n" " a pressure increase is injected, and when the button\n" " is released a pressure of zero is injected.\n" "\n" " If touch has been set, use \"touch_always=1\" to\n" " indicate whenever the mouse moves with no button\n" " pressed, a touch event of zero pressure should be\n" " sent anyway. Also use \"btn_touch=1\" to indicate a\n" " BTN_TOUCH keystroke press or release should be sent\n" " instead of a pressure change. Set \"dragskip=n\" to\n" " skip n dragged mouse touches (with pressure applied)\n" " before injecting one. To indicate the pressure that\n" " should be sent when there is a button click for a\n" " touchscreen device, specify pressure=n, e.g. n=5. The\n" " default is n=1.\n" "\n" " If a touch screen is being used (\"touch\" above)\n" " and it is having its input processed by tslib, you can\n" " specify the tslib calibration file via tslib_cal=<file>.\n" " For example, tslib_cal=/etc/pointercal. To get accurate\n" " or even usable positioning this is required when tslib\n" " is in use.\n" "\n" " When \"multitouch\", is specified, x11vnc will send\n" " multitouch events instead of single touch events.\n" " This is sometimes needed for some programs since they\n" " might not respond to single touch events." "\n" " The Linux uinput mechanism can be bypassed and one can\n" " write input events DIRECTLY to the devices instead.\n" " To do this, specify one or more of the following\n" " for the input classes: direct_rel=<device>\n" " direct_abs=<device> direct_btn=<device> or\n" " direct_key=<device>. The <device> file is usually\n" " something like /dev/input/event1 but you can specify\n" " any device file or pipe.

In general the\n" " two displays are usually nearby, e.g. on the same desk,\n" " and this allows the user to share a single pointer and\n" " keyboard between them. The user moves the mouse to\n" " an edge and then the mouse pointer appears to 'jump'\n" " to the other display screen. Thus it emulates what a\n" " single X server would do for two screens (e.g. :0.0 and\n" " :0.1) The illusion of a single Xserver with multiple\n" " screens is achieved by forwarding events to the 2nd\n" " one via the XTEST extension.\n" "\n" " What the x11vnc bcx_xattach command does is to perform\n" " some pointer movements to try to INDUCE xattach/x2x\n" " to 'jump' to the other display.

(Hereinafter, translation is included without limitation in\n" "the term \"modification\".)

You may copy and distribute verbatim copies of the Program's\n" "source code as you receive it, in any medium, provided that you\n" "conspicuously and appropriately publish on each copy an appropriate\n" "copyright notice and disclaimer of warranty; keep intact all the\n" "notices that refer to this License and to the absence of any warranty;\n" "and give any other recipients of the Program a copy of this License\n" "along with the Program.\n" "\n" "You may charge a fee for the physical act of transferring a copy, and\n" "you may at your option offer warranty protection in exchange for a fee.\n" "\n" " 2.

You may not copy, modify, sublicense, or distribute the Program\n" "except as expressly provided under this License. Any attempt\n" "otherwise to copy, modify, sublicense or distribute the Program is\n" "void, and will automatically terminate your rights under this License.\n" "However, parties who have received copies, or rights, from you under\n" "this License will not have their licenses terminated so long as such\n" "parties remain in full compliance.\n" "\n" " 5. You are not required to accept this License, since you have not\n" "signed it. However, nothing else grants you permission to modify or\n" "distribute the Program or its derivative works. These actions are\n" "prohibited by law if you do not accept this License. Therefore, by\n" "modifying or distributing the Program (or any work based on the\n" "Program), you indicate your acceptance of this License to do so, and\n" "all its terms and conditions for copying, distributing or modifying\n" "the Program or works based on it.\n" "\n" " 6. Each time you redistribute the Program (or any work based on the\n" "Program), the recipient automatically receives a license from the\n" "original licensor to copy, distribute or modify the Program subject to\n" "these terms and conditions.

If you cannot\n" "distribute so as to satisfy simultaneously your obligations under this\n" "License and any other pertinent obligations, then as a consequence you\n" "may not distribute the Program at all. For example, if a patent\n" "license would not permit royalty-free redistribution of the Program by\n" "all those who receive copies directly or indirectly through you, then\n" "the only way you could satisfy both it and this License would be to\n" "refrain entirely from distribution of the Program.\n" "\n" "If any portion of this section is held invalid or unenforceable under\n" "any particular circumstance, the balance of the section is intended to\n" "apply and the section as a whole is intended to apply in other\n" "circumstances.\n" "\n" "It is not the purpose of this section to induce you to infringe any\n" "patents or other property right claims or to contest validity of any\n" "such claims; this section has the sole purpose of protecting the\n" "integrity of the free software distribution system, which is\n" "implemented by public license practices. Many people have made\n" "generous contributions to the wide range of software distributed\n" "through that system in reliance on consistent application of that\n" "system; it is up to the author/donor to decide if he or she is willing\n" "to distribute software through any other system and a licensee cannot\n" "impose that choice.\n" "\n" "This section is intended to make thoroughly clear what is believed to\n" "be a consequence of the rest of this License.\n" " \n" " 8. If the distribution and/or use of the Program is restricted in\n" "certain countries either by patents or by copyrighted interfaces, the\n" "original copyright holder who places the Program under this License\n" "may add an explicit geographical distribution limitation excluding\n" "those countries, so that distribution is permitted only in or among\n" "countries not thus excluded.

Think of an x-y plane made with * graph paper. Each unit square in the graph paper (i.e. collection of * points (x,y) such that N < x < N+1 and M < y < M+1, N and M integers) * corresponds to one pixel in the unscaled fb. There is a solid * color filling the inside of such a square. A scaled pixel has width * 1/scale_fac, e.g. for "-scale 3/4" the width of the scaled pixel * is 1.333. The area of this scaled pixel is 1.333 * 1.333 (so it * obviously overlaps more than one source pixel, each which have area 1). * * We take the weight an unscaled pixel (source) contributes to a * scaled pixel (destination) as simply proportional to the overlap area * between the two pixels. One can then think of the value of the scaled * pixel as an integral over the portion of the graph paper it covers. * The thing being integrated is the color value of the unscaled source. * That color value is constant over a graph paper square (source pixel), * and changes discontinuously from one unit square to the next. * Here is an example for -scale 3/4, the solid lines are the source pixels (graph paper unit squares), while the dotted lines denote the scaled pixels (destination pixels): 0 1 4/3 2 8/3 3 4=12/3 |---------|--.------|------.--|---------|. | | . | . | |. | A | .

So we see the first scaled pixel (0 < x < 4/3 and 0 < y < 4/3) mostly overlaps with unscaled source pixel "A". The integration (averaging) weights for this scaled pixel are: A 1 B 1/3 C 1/3 D 1/9 * * The Red, Green, and Blue color values must be averaged over separately * otherwise you can get a complete mess (except in solid regions), * because high order bits are averaged differently from the low order bits. * * So the algorithm is roughly: * * - Given as input a rectangle in the unscaled source fb with changes, * find the rectangle of pixels this affects in the scaled destination fb. * * - For each of the affected scaled (dest) pixels, determine all of the * unscaled (source) pixels it overlaps with. * * - Average those unscaled source values together, weighted by the area * overlap with the destination pixel. Average R, G, B separately. * * - Take this average value and convert to a valid pixel value if * necessary (e.g. rounding, shifting), and then insert it into the * destination framebuffer as the pixel value. * * - On to the next destination pixel... * * ======================================================================== * * For expanding, e.g. -scale 1.1 (which we don't think people will do * very often... or at least so we hope, the framebuffer can become huge) * the situation is reversed and the destination pixel is smaller than a * "graph paper" unit square (source pixel). Some destination pixels * will be completely within a single unscaled source pixel. * * What we do here is a simple 4 point interpolation scheme: * * Let P00 be the source pixel closest to the destination pixel but with * x and y values less than or equal to those of the destination pixel. * (for simplicity, think of the upper left corner of a pixel defining the * x,y location of the pixel, the center would work just as well). So it * is the source pixel immediately to the upper left of the destination * pixel. Let P10 be the source pixel one to the right of P00. Let P01 * be one down from P00. And let P11 be one down and one to the right * of P00. They form a 2x2 square we will interpolate inside of. * * Let V00, V10, V01, and V11 be the color values of those 4 source * pixels. Let dx be the displacement along x the destination pixel is * from P00. Note: 0 <= dx < 1 by definition of P00. Similarly let * dy be the displacement along y. The weighted average for the * interpolation is: * * V_ave = V00 * (1 - dx) * (1 - dy) * + V10 * dx * (1 - dy) * + V01 * (1 - dx) * dy * + V11 * dx * dy * * Note that the weights (1-dx)*(1-dy) + dx*(1-dy) + (1-dx)*dy + dx*dy * automatically add up to 1. It is also nice that all the weights are * positive (unsigned char stays unsigned char). The above formula can * be motivated by doing two 1D interpolations along x: * * VA = V00 * (1 - dx) + V10 * dx * VB = V01 * (1 - dx) + V11 * dx * * and then interpolating VA and VB along y: * * V_ave = VA * (1 - dy) + VB * dy * * VA * v |<-dx->| * -- V00 ------ V10 * dy | | * -- | o...|... "o" denotes the position of the desired * ^ | . | . destination pixel relative to the P00 * | . | . source pixel. * V10 ----.- V11 . * ........ * | * VB * * * Of course R, G, B averages are done separately as in the shrinking * case.

These different\n" " recipes are referred to as \\\"visuals\\\". E.g. for 8bpp there is\n" " a PseudoColor visual that maintains a mapping (that can be changed\n" " dynamically) of the pixel values (256 possible ones) into RGB values.\n" " Other 8bpp visuals, e.g. StaticGrey and TrueColor have fixed, regular\n" " mappings and so provide less variation in kinds of colors.\n" "\n" " A visual's \\\"depth\\\" is how many of the pixels are used in the\n" " actual recipe. This may sound wasteful (i.e. not using some of the\n" " bits), but for 32bpp (4 billion colors) that is too much and nearly\n" " always only 24 for them are used. The most common Visual seems to\n" " be depth 24 TrueColor at 32bpp. This provides 16 million colors\n" " which is more than the number of pixels on most screens (1280x1024 =\n" " 1.3 million pixels). Another sometimes used visual that ignores some\n" " bits is depth 15 TrueColor at 16bpp.\n" "\n" "OK, now, finally, to the Overlay Visuals. Some hardware (or software\n" "emulations) allow different depth visuals to be used on the display\n" "at the same time.

This is sometimes referred to as \\\"8+24\\\" mode. Furthermore,\n" "a speedup is achieved because writing graphics data to, say, the 8bit\n" "visual does not destroy the image data in the 24bit visual. Evidently\n" "popup menus can be done very quickly this way: they use the 8bit visual\n" "and when the popup goes away the graphics data in the 24bit visual is\n" "immediately reexposed without having the application redraw it.\n" "\n" "Also, some legacy applications can only use 8bpp visuals. But in these\n" "days of high color graphics and web browsers one would like the rest\n" "of the desktop to use depth 24 visuals.

Schindelin) * x0rfbserver, the original native X vnc server (Jens Wagner) * krfb, the KDE desktopsharing project (Tim Jansen) * * Please see http://www.karlrunge.com/x11vnc for the most up-to-date * information about x11vnc. Some of the following text may be out * of date. * * The primary goal of this program is to create a portable and simple * command-line server utility that allows a VNC viewer to connect * to an actual X display (as the above do). The only non-standard * dependency of this program is the static library libvncserver.a. * Although in some environments libjpeg.so or libz.so may not be * readily available and needs to be installed, they may be found * at ftp://ftp.uu.net/graphics/jpeg/ and http://www.gzip.org/zlib/, * respectively. To increase portability it is written in plain C. * * Another goal is to improve performance and interactive response. * The algorithm of x0rfbserver was used as a base. Many additional * heuristics are also applied. * * Another goal is to add many features that enable and incourage creative * usage and application of the tool. Apologies for the large number * of options! * * To build: * * Obtain the libvncserver package (http://libvncserver.sourceforge.net). * As of 12/2002 this version of x11vnc.c is contained in the libvncserver * CVS tree and released in version 0.5. * * gcc should be used on all platforms. To build a threaded version put * "-D_REENTRANT -DX11VNC_THREADED" in the environment variable CFLAGS * or CPPFLAGS (e.g. before running the libvncserver configure). The * threaded mode is a bit more responsive, but can be unstable (e.g. * if more than one client the same tight or zrle encoding). * * Known shortcomings: * * The screen updates are good, but of course not perfect since the X * display must be continuously polled and read for changes and this is * slow for most hardware. This can be contrasted with receiving a change * callback from the X server, if that were generally possible... (UPDATE: * this is handled now with the X DAMAGE extension, but unfortunately * that doesn't seem to address the slow read from the video h/w). So, * e.g., opaque moves and similar window activity can be very painful; * one has to modify one's behavior a bit. * * General audio at the remote display is lost unless one separately * sets up some audio side-channel such as esd. * * It does not appear possible to query the X server for the current * cursor shape. We can use XTest to compare cursor to current window's * cursor, but we cannot extract what the cursor is... (UPDATE: we now * use XFIXES extension for this. Also on Solaris and IRIX Overlay * extensions exists that allow drawing the mouse into the framebuffer) * * The current *position* of the remote X mouse pointer is shown with * the -cursor option. Further, if -cursor X is used, a trick * is done to at least show the root window cursor vs non-root cursor. * (perhaps some heuristic can be done to further distinguish cases..., * currently "-cursor some" is a first hack at this) * * Under XFIXES mode for showing the cursor shape, the cursor may be * poorly approximated if it has transparency (alpha channel). * * Windows using visuals other than the default X visual may have * their colors messed up. When using 8bpp indexed color, the colormap * is attempted to be followed, but may become out of date. Use the * -flashcmap option to have colormap flashing as the pointer moves * windows with private colormaps (slow). Displays with mixed depth 8 and * 24 visuals will incorrectly display windows using the non-default one. * On Sun and Sgi hardware we can to work around this with -overlay. * * Feature -id <windowid> can be picky: it can crash for things like * the window not sufficiently mapped into server memory, etc (UPDATE: * we now use the -xrandr mechanisms to trap errors more robustly for * this mode). SaveUnders menus, popups, etc will not be seen. * * Under some situations the keysym unmapping is not correct, especially * if the two keyboards correspond to different languages. The -modtweak * option is the default and corrects most problems. One can use the * -xkb option to try to use the XKEYBOARD extension to clear up any * remaining problems. * * Occasionally, a few tile updates can be missed leaving a patch of * color that needs to be refreshed. This may only be when threaded, * which is no longer the default. * * There seems to be a serious bug with simultaneous clients when * threaded, currently the only workaround in this case is -nothreads * (which is now the default). */ /* -- x11vnc.c -- */ #include "x11vnc.h" #include "xwrappers.h" #include "xdamage.h" #include "xrecord.h" #include "xevents.h" #include "xinerama.h" #include "xrandr.h" #include "xkb_bell.h" #include "win_utils.h" #include "remote.h" #include "scan.h" #include "gui.h" #include "help.h" #include "user.h" #include "cleanup.h" #include "keyboard.h" #include "pointer.h" #include "cursor.h" #include "userinput.h" #include "screen.h" #include "connections.h" #include "rates.h" #include "unixpw.h" #include "inet.h" #include "sslcmds.h" #include "sslhelper.h" #include "selection.h" #include "pm.h" #include "solid.h" #include "xi2_devices.h" /* * main routine for the x11vnc program */ void watch_loop(void);

If you Press start it will be shown as well and you will be asked to confirm running it. If you want to use a saved profile \"rc file\" you can do \"Misc -> rc\" and select the file and simply start x11vnc using the rc file. Alternatively, you could first use the \"Actions -> load-settings\" action to load in an \"rc file\" and then press \"Actions -> start\" to start up x11vnc based on those values. " set helptext(stop) " The \"Actions -> stop\" action sends a signal to the running x11vnc server indicating it should shutdown all connections and exit. The GUI stays running in case you want to start a new x11vnc or attach to another one. Use \"Actions -> Quit\" if you then want to have the gui exit.

This can be done even in the attached state. Intended for debugging the gui. The help item for \"Actions -> start\" gives the same info. If you want to load in a saved profile \"rc file\" use \"Misc -> rc\" and select the file. \"Actions -> load-settings\" does a similar thing with an rc-file, but reading the file and setting the gui variables to its values. " set helptext(debug_gui) " Set debug_gui to get more output printed in the text area. " set helptext(detach) " No longer be associated with the x11vnc server. Switch to the non-connected state. The x11vnc server keeps running: it does not exit. You can either later reattach to it \"Actions -> attach\", or start up a new x11vnc \"Actions -> start\", or exit \"Actions -> Quit\". " set helptext(attach) " Attach to a running x11vnc server, if possible. Switches to connected state if successful. Usually the channel used to attach is via the X display (VNC_CONNECT rootwin property) being polled by the x11vnc server. To change or set the X display to use do \"Displays -> display\". Sometimes the \"-connect /path/to/filename\" is used as the comunication channel. The running x11vnc has to know that \"/path/to/filename\" is the communication channel (i.e. it is using the same -connect option). " set helptext(ping) " Check if x11vnc still responds to \"ping\" remote command. " set helptext(update-all) " Query the x11vnc server for the current values of all variables. Populate the values into the gui's database. Normally the gui will refresh this info every time it interacts with the x11vnc server (including after a few minutes of inactivity), so one doesn't need to use this action very often (unless something else is changing the state of the x11vnc server, or new clients have connected, etc). " set helptext(clear-all) " Forget any variable settings either entered in by you or set at the default. Basically sets everything to 0 or the string (unset). This action is only available in \"startup\" mode, not when connected to a running x11vnc server (in that case the variable settings reflect the state of the running x11vnc). To detach from a running x11vnc server use \"Actions -> detach\"; to completely stop the x11vnc server use \"Actions -> stop\". " set helptext(defaults-all) " Reset all variable settings to the default values. Basically sets everything to the default queries \"x11vnc -QD var\" retrieved at startup. This action is only available in \"startup\" mode, not when connected to a running x11vnc server (in that case the variable settings reflect the state of the running x11vnc).

" set helptext(save-settings) " Construct a ~/.x11vncrc file based on the current settings and offer to save it in a file (default ~/.x11vncrc). If saved in a file other than the default, you can access the profile by using the \"-rc <filename>\" option when starting x11vnc. If an rc file entry begins with \"#d\" that means the current setting is at the Default value and so you probably want to leave it commented out with the \"#\" character. If an rc file entry begins with \"#?\" that means we think you probably do not really want to force the value to this setting. In either case, feel free to uncomment the line and/or change any of the parameter values in the file. " set helptext(all-settings) " Displays the gui's database of all of the x11vnc server's current settings. Use \"Actions -> update-all\" or \"Control+R\" to refresh this list if it ever gets out of sync. " set helptext(remote-cmd) " Run a remote command (-R) or query (-Q) directly. Only a few remote commands are not on a menu, but for those few you can run the command directly this way. Just enter the command into the Entry box when prompted. Use the prefix \"Q:\" to indicate a -Q query. Examples: \"zero:20,20,100,100\", \"Q:ext_xfixes\" " set helptext(stop+quit) " Send the stop command to the x11vnc server, then terminate the tkx11vnc gui. " set helptext(show-logfile) " View the current contents of the logfile (if it exists and is accessible by the gui process). " set helptext(tail-logfile) " Run the tail(1) command with -f option on the logfile in an xterm. (if it exists and is accessible by the gui process). " set helptext(Quit) " Terminate the tkx11vnc gui. Any x11vnc server will be left running. " set helptext(current) " Shows a menu of currently connected VNC clients on the x11vnc server. Allows you to find more information about them, change their input permissions, or disconnect them. Note that the File transfer permission only applies to UltraVNC file transfer, not TightVNC file transfer. You will be prompted to confirm any disconnections. " set helptext(client) " After selecting a VNC client from the \"Clients -> current\" menu, you will be presented with a dialog that shows the information about the VNC client. You can choose to disconnect the client by clicking on the \"Disconnect\" checkbox and pressing \"OK\". There will be a confirmation dialog to doublecheck. Alternatively, you can fine tune the VNC client's input permissions by selecting any of the Keystrokes, Mouse-Motion, Button-Click, Clipboard-Input, or Files checkboxes and pressing \"OK\". This is like the \"-input\" option but on a per-client basis. To not change any aspects of the VNC client press \"Cancel\". " set helptext(solid_color) " Set the -solid color value.

" set helptext(simple-gui) " Toggle between menu items corresponding the most basic ones and all possible settings. I.e. toggle between a simple gui and one for power users. " set helptext(Tray) " The tray/icon mode (started with \"x11vnc -gui tray ...\", etc.) presents a small icon that indicates the status of the running x11vnc server. Depending on your environment, this icon may be embedded in a system tray or applet dock, or simply be a standalone window. \"-gui tray\" will attempt to embed the icon in the system tray, while \"-gui icon\" is for a standalone window. Use \"-gui tray=setpass\" (or icon=setpass) to be prompted to set the session password at startup. When the icon has a light background, that means no VNC viewers are currently connected to the VNC display. When the icon has a dark background (i.e. reverse-video), that means at least one VNC viewer is connected to the VNC display. Moving the mouse pointer over the icon will popup a \"status balloon\" indicating the VNC display name and the names and info of any connected VNC viewers. Press the middle mouse button if the balloon does not appear. Clicking the left or right mouse button on the icon displays a menu of actions: Properties - Brings up the Properties dialog to set some basic parameters. The full tkx11vnc GUI may be accessed via the \"Advanced ...\" button. Press \"Help\" in the Properties dialog for more info. Help - Displays this help text. New Client - Presents an entry box where you type in the name of a computer that is running a VNC viewer in \"listen\" mode (e.g. vncviewer -listen). For a non-standard listening port use \"host:port\". Pressing \"OK\" will initiate the reverse connection. Use a blank hostname to skip it. Disconnect - Shows a popup menu of connected clients. Click on one to disconnect it, or click on \"All Clients\" disconnect all clients. Window View - Switch between the \"full\" gui (also known as \"Advanced\"), \"icon\" mode (small icon window with popups), or \"tray\" mode (small icon embedded in the system tray). This is a shortcut for the action: \"Properties -> Advanced -> Misc -> WindowView\". Stop x11vnc - Directs the x11vnc server to disconnect all vncviewers and then exit. The tray/icon GUI then exits as well. Logfile - Show the logfile if x11vnc is being run with one. Custom - If you have a \$HOME/.x11vnc.gui file each uncommented line in it becomes an additional menu item for this menu. The remote control command is run directly via \"x11vnc -R <command>\", or if prefixed with \"action:\" runs a gui internal action, or if \"sep\" adds a separator. Set X11VNC_CUSTOM_GUI to use a different filename. Example file contents: scale:3/4 scale:1 scale_cursor:1 sep action:all-settings #debug_keyboard sep action:Quit Termination: If the x11vnc server stops for any reason, the tray/icon gui will exit. If you delete the tray/icon (e.g. X out button), that is the same as the \"Stop x11vnc\" action in the menu. (This will disconnect any VNC viewer you are currently using to access the display since the x11vnc server is terminated). To terminate the tray/icon gui window but not the x11vnc server press Control-C on the tray/icon window. You can also do this (and much more) via Properties -> Advanced -> Actions -> Quit " set helptext(NewClient) " New Client - Presents an entry box where you type in the name of a computer that is running a VNC viewer in \"listen\" mode (e.g. vncviewer -listen). For a non-standard listening port use \"host:port\". Pressing \"OK\" will initiate the reverse connection. Use a blank hostname to skip it, or delete (\"X-out\") the window. " set helptext(Properties) " The Properties dialog allows you to set some basic parameters of a running x11vnc server. After modifying them press \"OK\" or \"Apply\" to apply the changes, or press \"Cancel\" to skip applying them. Accept Connections: Toggles whether VNC viewers are allowed to connect or not. It corresponds to the \"-R unlock\" and \"-R lock\" remote-control commands. Ask for Confirmation: Toggles whether a popup menu will be presented at the X display when a new VNC viewer attempts to connect. The person sitting at the X display can choose to accept or reject the connection or accept the connection in ViewOnly mode. It corresponds to the \"-R accept:popup\" and \"-R accept:\" remote-control commands. All Clients ViewOnly: Toggles whether the entire VNC desktop is view only. All clients will only be able to watch when this is set (regardless of how they logged in). It corresponds to the \"-R viewonly\" and \"-R noviewonly\" remote-control commands. Shared: Toggles whether multiple simultaneous viewer connections are allowed or not. It corresponds to the \"-R shared\" and \"-R noshared\" remote-control commands. Advertise Service (Zeroconf): Toggles whether this VNC server should advertize itself via Zeroconf (also called Bonjour, mDNS, and avahi). Then VNC viewers can then find this service on the local network. It corresponds to the \"-R zeroconf\" and \"-R nozeroconf\" remote-control commands. Serve Java Viewer Applet: Toggles whether this VNC server should serve up a Java VNC Viewer applet via HTTP on http://hostname:5800/ (or port 5800+n for VNC port 5900+n). A java enabled Web Browser can then connect to the desktopby VNC. If SSL is active then the HTTPS URL https://hostname:5900/ (etc.) will work as well. This requires the x11vnc java viewer jar file (shared/x11vnc/classes) to be installed. It corresponds to the \"-R http\" and \"-R nohttp\" remote commands. Solid Background Color: To improve VNC performance, if this option is set, then x11vnc will try to make the desktop background a solid color (which compresses extremely well compared to photo images, etc.) It corresponds to the \"-R solid\" and \"-R nosolid\" remote commands. Password: Lets you set the session password viewers may use to gain full access to the display. This will only work if x11vnc was started with the -gui icon or -gui tray mode. ViewOnly Password: Lets you set the session password viewers may use to gain view only access to the display. This will only work if x11vnc was started with the -gui icon or -gui tray mode. NOTE: These \"session\" passwords only last for the current x11vnc session (they are not remembered, see the -storepasswd, -passwdfile, and -rfbauth x11vnc options for using stored passwords). If you set \"Password\" to the empty string that makes the \"ViewOnly Password\" empty as well and removes the need for any password to log in. If you set \"ViewOnly Password\" to the empty string that just removes the ViewOnly log in aspect: \"Password\" is still required to log in. - The \"Help\" button shows this help text. - The \"Advanced ...\" button replaces the Properties dialog with the full tkx11vnc GUI. All dynamic settings can be modified in the full GUI. ========================================================================== Don't Lock Yourself Out: If you are sitting at the physical X display you cannot get into too much trouble setting the Properties dialog values. However IF you are using a VNC Viewer to REMOTELY access the X display some items in the Properties dialog can lock you out of further access: \"Accept Connections\" if you disable this remotely, and accidentally disconnect your VNC viewer then you will not be able to reconnect. \"Ask for Confirmation\" if you enable this only someone sitting at the X display can confirm any new VNC connections. Furthermore, any current VNC viewers will be blocked while waiting for the confirmation (times out in 120 sec by default). \"All Clients ViewOnly\" if you enable this remotely, well you can no longer provide input to disable it. If you do lock yourself out you could log in remotely and start up a second x11vnc and connect to that one to try to fix things in the first one. Note that if there are two or more x11vnc's on the same display the use of the GUI may be ill-behaved. Terminate the second x11vnc as soon as you have fixed the setting in the first one. Use of a remote control command, e.g. \"x11vnc -R noviewonly\" or \"x11vnc -R unlock\" is a good way to avoid this problem. " set helptext(all) $helpall set helptext(Misc-Tuning:) " x11vnc has what seems like hundreds of tuning parameters! In this sub-menu we place some lesser used ones. Most likely you'll want to leave them at their default values, but you can try them out quickly with the gui to see if they improve things. " set helptext(Passwords:) " The items in this sub-menu pertain to setting passwords. Note that x11vnc has two types of password files: RealVNC-style ones (you can create them with x11vnc -storepasswd or other VNC utility program) you use these via -rfbauth; and plain-text file passwords you use via -passwdfile. Normally passwords cannot be changed by remote-control (e.g. the gui), but for the case of the \"Icon\" and \"Tray\" modes this constraint has been relaxed. In neither the RealVNC-style nor the plain-text file cases should the password files be readable by users you do not want to access the VNC server. Contrary to popular belief, the RealVNC-style passwords are not encrypted, merely obscured. x11vnc has the even less secure -passwd and -viewpasswd supplied on the command line. Be careful with these since they could be read by users with something like the ps(1) command. On some operating systems x11vnc tries to quickly overwrite them on the command line but it doesn't work everywhere. Regarding ViewOnly passwords (where a VNC client using that password can only watch the screen, not interact with it), this is not available with -rfbauth, but only with -passwdfile, -passwd, and -viewpasswd. " set helptext(SSL:) " In this sub-menu we provide the options related to SSL encrpytion and authentication. There is a built-in mode (-ssl) using the OpenSSL library, and a 2nd using the external stunnel program (-stunnel, that needs to be installed on the system). Either may require or benefit from having PEM certificate files specified. " set helptext(Misc-Perms:) " In this sub-menu we provide some lesser used permission options. Regarding -alwaysshared, -nevershared, and -dontdisconnect, you probably should never use them and just use x11vnc's -shared and -forever options instead (these give basically the same functionality and if you mixed them too much unexpected things may happen). " #' set helptext(AlphaBlending:) " In this sub-menu we provide some tweak parameters for cursors (little icon at the mouse pointer) that have transparency (i.e. an Alpha channel in addition to Red, Green, and Blue RGB channels). For these cursors, some of the graphics underneath the cursor is allowed to be blended in: e.g. a drop-shadow (a terrible effect IMNSHO). AlphaBlending for x11vnc is only available when the XFIXES X extension is present (since otherwise it cannot see the cursors at all and so applies heuristics to show some fake cursors). AlphaBlending is only a problem with x11vnc when the cursors are not opaque. Opaque cursors (e.g. bitmap or simply colored cursor) are rendered correctly by x11vnc. Only when there is transparency does x11vnc have to make some approximation to transform the cursor to be opaque (the VNC protocol does not provide for an alpha channel in cursors, only RGB). The items in this sub-menu let you tweak x11vnc's approximation scheme for cursors with transparency. Hopefully you won't have to use them. Certain cursor \"themes\" may require adjustment however. " #' set helptext(OverlayVisuals:) " In this sub-menu are some options that involve fixing color problems for \"Overlay\" or \"Multi-Depth\" visuals. This problem is rare since overlay and multi-depth visual video hardware is rare. Some Sun, SGI, and HP machines are known to have them. The short answer is if you have a multi-depth visual display (e.g. 8 and 24 bits), and you see messed up colors in x11vnc try the \"-overlay\" option on Solaris or IRIX. A brief Background on pixels, color, and visuals: Pixels (picture elements) are kept in video memory as a certain number of bits-per-pixel (bpp). Most common are 8bpp, 16bpp, and 32bpp. Less common are 24bpp, 4bpp, and 1bpp (monochrome). How pixel values (i.e. values of the bits) are rendered into colors on the screen can be done via different \"Recipes\". These different recipes are referred to as \"visuals\". E.g. for 8bpp there is a PseudoColor visual that maintains a mapping (that can be changed dynamically) of the pixel values (256 possible ones) into RGB values. Other 8bpp visuals, e.g. StaticGrey and TrueColor have fixed, regular mappings and so provide less variation in kinds of colors. A visual's \"depth\" is how many of the pixels are used in the actual recipe. This may sound wasteful (i.e. not using some of the bits), but for 32bpp (4 billion colors) that is too much and nearly always only 24 for them are used. The most common Visual seems to be depth 24 TrueColor at 32bpp. This provides 16 million colors which is more than the number of pixels on most screens (1280x1024 = 1.3 million pixels). Another sometimes used visual that ignores some bits is depth 15 TrueColor at 16bpp. OK, now, finally, to the Overlay Visuals. Some hardware (or software emulations) allow different depth visuals to be used on the display at the same time. The pixels of windows using different depth visuals may overlap. The most common seems to be both 8 and 24 depth visuals on a 32bpp setup. 24 of the pixels can be used for one visual and the remaining 8 for the other. This is sometimes referred to as \"8+24\" mode. Furthermore, a speedup is achieved because writing graphics data to, say, the 8bit visual does not destroy the image data in the 24bit visual. Evidently popup menus can be done very quickly this way: they use the 8bit visual and when the popup goes away the graphics data in the 24bit visual is immediately reexposed without having the application redraw it. Also, some legacy applications can only use 8bpp visuals. But in these days of high color graphics and web browsers one would like the rest of the desktop to use depth 24 visuals. They often work on the multi depth visuals. How does this effect x11vnc? x11vnc nearly always polls the root window (container of all other windows). The root window will be one depth, e.g. 8 or 24. Any windows using the *other* depth will appear to have messed up colors (or just be black or some other solid color) when viewed via x11vnc. How to fix? Solaris and IRIX provide an API to extract the full snapshot of the display with all the colors correct. It comes to x11vnc as depth 24 TrueColor. To enable this use the \"-overlay\" option. Performance may be slower, but if the colors are correct that is a big improvement. " set helptext(8-Bit-Color:) " Some older displays (e.g. with limited Video RAM) use 8 bits-per-pixel color. This allows for only 256 different colors on the screen at the same time. This sometimes leads to problems with viewing these 8bpp displays via x11vnc. This sub-menu has some options that correspond to workarounds for this case. If you can configure the machine to use 16bpp it may be worth it to avoid the color problems (e.g. color flashing as the 8bit colormap is switched). " set helptext(SubWindow:) " This sub-menu has a couple options regarding having x11vnc poll a single window, not the entire display. This way just the window is shared. Note if the application pops up multiple windows they are not tracked and shared. So this is not application sharing. The application has to be very simple (e.g. a simple terminal or the image window on a webcam) for this mode to be usable. " set helptext(ResizeRotate:) " This sub-menu has some options regarding screens that support the X Resize, Reflection, and Rotation Extension (RANDR), and one expects screen resizing, reflection, or rotation to take place during the x11vnc session. This is pretty rare, but x11vnc seems to handle it reasonably well using this X extension. This mode is on by default in -id mode to try to track the changing size of the SubWindow. It is not on by default for full-screen mode because of the extra overhead, etc. " set helptext(WireFrame:) " This sub-menu has some options for the x11vnc wireframing speedup scheme. For x11vnc, Wireframing means to watch for toplevel windows being Opaquely Moved or Resized. When x11vnc detects this, it stops polling the screen and simply shows a \"wireframe\" outline of the window as it is being moved or resized. This avoids \"screen polling thrashing\" when the screen is changing so rapidly during this period. For various reasons this is usually much faster then letting the window manager do its own wireframing (you are encouraged to do Opaque moves and resizes when using x11vnc!) Also, once a moved window is released in its new position, x11vnc uses the VNC CopyRect encoding to very efficiently update the VNC viewers (each just copies the image data locally). This sort of scheme was used much in the 1990's on local displays because video hardware was slow at the time. x11vnc tries to use this same trick as a speedup for its activities (the network is much slower than video hardware writes, and the video hardware reads that x11vnc uses to poll the screen are still slow today). " #'" set helptext(Safe:) " In this sub-menu are some options for making x11vnc operations more, or less, safe. E.g. disable the running of external commands, etc. You can also turn off the Remote control channel (NOTE that doing that will disable the GUI from being able to communicate with x11vnc). " set helptext(X-ext:) " In this sub-menu are a few rarely used options regarding some X extensions used by x11vnc. " set helptext(Clipping:) " In this sub-menu are some options regarding clipping or blacking out portions of the Screen. E.g. under XINERAMA when the multiple monitors are not the same size. " set helptext(Misc-Screen:) " In this sub-menu are some little used options modifying aspects of the screen source. " set helptext(Settings:) " In this sub-menu are some options for saving and loading option settings. The default file to store settings in is ~/.x11vncrc, but you can save different \"profiles\" in other files for later use. " set helptext(Java-applet:) " In this sub-menu are some options for running the built-in HTTP server that delivers the TightVNC Java VNC Viewer applet (VncViewer.jar) to clients. The viewer runs in their Web browser. The default port listened on is 5800, so the URL is typically: http://hostname:5800/ but this can be altered by -httpport, etc. " set helptext(Chat:) " In this sub-menu are some options for enabling a local chat window and starting or stopping the current chat. This is the UltraVNC Text Chat support in x11vnc. " set helptext(ScrollCopyRect:) " This sub-menu has some options for the x11vnc Scroll detection and CopyRect speedup scheme. For this mode, x11vnc \"spies\" on communication between the X server and applications using the RECORD extension. It looks for various patterns to detect a scrolled window. This only works for some applications, fortunately some important ones. Once the scroll is detected it uses the VNC CopyRect encoding for a big speedup. Screen polling is also sped up for this scheme. There are many tweakable parameters for this mode and they are described in the sub-menu items. " set helptext(XDAMAGE:) " The DAMAGE X extension allows the X server to send signals to x11vnc telling it which regions of the screen have been changed. This improves x11vnc's performance markedly. The DAMAGE extension must be available on the display for this to work. Unfortunately DAMAGE cannot be trusted completely for the changed regions, because often the reported changed region is much larger than the actual changed regions. Nevertheless, x11vnc uses the DAMAGE information very effectively as hints to improve its performance. The items in the sub-menu allow tweaking x11vnc's DAMAGE algorithm. " set helptext(Ncache:) " A simple client-side (viewer) caching scheme is enabled with the \"-ncache n\" option. It simply uses \"n\" framebuffer sized areas below the actual display for caching window pixel data. Drawbacks are it uses a lot of RAM (roughly n times more), and the pixels cache area is visible in the viewers. The items in the sub-menu allow tweaking x11vnc's -ncache algorithm. " set helptext(SharedMemory:) " This sub-menu provides some options regarding SYSV shared memory usage (shm) by x11vnc. Usually you want shm turned on because the x11vnc process is nearly always running on the same machine the X server process is running on. SharedMemory gives a performance speedup. However, if you need to modify this scenario for special usage these options allow you to. " set helptext(Misc-Debug:) " This sub-menu contains a lot of debugging parameters usually used for debugging x11vnc itself. This is unlike the -debug_pointer and -debug_keyboard options that are useful in learning information, quirks, etc. about your local display and environment. " set helptext(Selection:) " This sub-menu contains some options centering around the Selection (also referred to as the Clipboard, Cutbuffers, etc). x11vnc will try to exchange the selections between the VNC viewers and the X server. You can adjust that behavior with these options. " set helptext(WindowView) " Set the Window View Mode for the gui. There are three modes: - full: Presents the full gui (Actions, Clients, etc, buttons, and the Text area and Set/Entry box). - icon: Presents a small icon instead of the full gui. Moving the mouse over it shows the VNC display name and any connected clients. Clicking on the icon pops up a menu of actions to perform. Among them is \"Properties\" that allows setting more parameters. Clicking on \"Advanced\" in \"Properties\" brings up the full gui. - tray: Attempt to embed the small icon in the system tray. If this fails it will resort to icon mode where the small icon is a standalone window. Note that in \"full\" mode if you delete the full gui window the gui terminates (but the x11vnc server keeps running). However under \"icon\" or \"tray\" mode if you bring up the full gui window via \"Properties -> Advanced\" and then delete it the gui does NOT terminate. Also note that by default in \"icon\" mode if you delete the icon window both the gui *and* the x11vnc server terminate. " set helptext(gui) " tkx11vnc is a simple frontend to x11vnc. Nothing fancy, it merely provides an interface to each of the many x11vnc command line options and remote control commands. See \"Help -> all\" for much info about x11vnc. For a simpler gui, run x11vnc in \"tray\" or \"icon\" mode such as \"-gui tray\", \"-gui icon\", or \"-gui tray=setpass\". In that mode the full gui is only available under \"Advanced ...\". Also, \"-gui ez\" will show fewer menu items (toggle via Misc -> simple_gui) All menu items have a (?) button one can click on to get more information about the option or command. There are two states tkx11vnc can be in: 1) Available to control a running x11vnc process. 2) Getting ready to start a x11vnc process. Most people will just use state 1). In state 1) the Menu items available in the menus are those that correspond to the x11vnc \"remote control\" commands. See the -remote entry under \"Help -> all\" for a complete list. Also available is the \"Actions -> stop\" item to shut down the running x11vnc server, thereby changing to state 2). There are other actions available too. In state 2) the Menu items available in the menus (\"Actions\", \"Clients\", etc.) are those that correspond to command line options used in starting an x11vnc process, and the \"Actions -> start\" item executes x11vnc thereby changing to state 1). To see what x11vnc startup command you have built so far, look at the (?) help for \"Actions -> start\" and it will show you what the command looks like. There is much overlap between the menu items available in state 1) and state 2), but it is worth keeping in mind it is not 100%. For example, you cannot set passwords or password files in state 1). (update: simple password setting is now allowed in \"tray\" or \"icon\" mode). Also note that there may be *two* separate X displays involved, not just one: 1) the X display x11vnc will be polling (and making available to VNC viewers), and 2) the X display this GUI is intended to display on. For example, one might use ssh to access the remote machine where the GUI would display on :11 and x11vnc would poll display :0. By default the gui will display on the value in the DISPLAY env. variable followed by the value from the -display option. To override this, use something like: \"-gui otherhost:0\", etc. GUI components: --- ---------- 1) At the top of the gui is a info text label where information will be posted, e.g. when traversing menu items text indicating how to get help on the item and its current value will be displayed. 2) Below the info label is the area where the menu buttons, \"Actions\", \"Clients\", etc., are presented. If a menu item has a checkbox, it corresponds to a boolean on/off variable. Otherwise it is either a string variable, or an action not associated with a variable (for the most part). 3) Below the menu button area is a label indicating the current x11vnc X display being polled and the corresponding VNC display name. Both will be \"(*none*)\" when there is no connection established. 4) Below the x11 and vnc displays label is a text area there scrolling information about actions being taken and commands being run is displayed. To scroll click in the area and use PageUp/PageDown or the arrow keys. 5) At the bottom is an entry area. When one selects a menu item that requires supplying a string value, the label will be set to the parameter name and one types in the new value. Then one presses the \"OK\" button or presses \"Enter\" to set the value. Or you can press \"Cancel\" or \"Escape\" to avoid changing the variable. Many variables are boolean toggles (for example, \"Permissions -> viewonly\") or Radio button selections. Selecting these menu items will NOT activate the entry area but rather toggle the variable immediately. CASCADES BUG: There is a bug not yet worked around for the cascade menus where the (?) help button gets in the way. To get the mouse over to the cascade menu click and release mouse to activate the cascade, then you can click on its items. Dragging with a mouse button held down will not work (sorry!). Key Bindings: In the Text Area: Control-/ selects all of the text. Anywhere: Control-d invokes \"Actions -> detach\" Anywhere: Control-a invokes \"Actions -> attach\" Anywhere: Control-p invokes \"Actions -> ping\" Anywhere: Control-u and Control-r invoke \"Actions -> update-all\" " set under_wally " Misc: Since x11vnc has so many settings and to avoid further confusion, the libvncserver options: -alwaysshared -nevershared -dontdisconnect are not available for changing in a running x11vnc (even though it is feasible). These options overlap with the x11vnc options -shared and -forever which are hopefully enough for most usage. They may be specified for x11vnc startup if desired. " global beginner_mode if {$beginner_mode} { set helptext(gui) " tkx11vnc is a simple frontend to x11vnc. It is currently running in \"ez\" or \"simple\" mode.

One would next run something like this on the local machine: "vncviewer hostname:N" where "hostname" is the name of the machine running x11vnc and N is XXXX - 5900, i.e. usually "vncviewer hostname:0". .PP By default x11vnc will not allow the screen to be shared and it will exit as soon as the client disconnects. See \fB-shared\fR and \fB-forever\fR below to override these protections. See the FAQ for details how to tunnel the VNC connection through an encrypted channel such as .IR ssh (1). In brief: .IP ssh \fB-t\fR \fB-L\fR 5900:localhost:5900 far-host 'x11vnc \fB-localhost\fR \fB-display\fR :0' .PP % vncviewer -encodings 'copyrect tight zrle hextile' localhost:0 .PP Also, use of a VNC password (-rfbauth or \fB-passwdfile)\fR is strongly recommended. .PP For additional info see: http://www.karlrunge.com/x11vnc/ and http://www.karlrunge.com/x11vnc/faq.html .PP Config file support: if the file $HOME/.x11vncrc exists then each line in it is treated as a single command line option. Disable with \fB-norc.\fR For each option name, the leading character "-" is not required. E.g. a line that is either "forever" or "\fB-forever\fR" may be used and are equivalent. Likewise "wait 100" or "\fB-wait\fR \fI100\fR" are acceptable and equivalent lines. The "#" character comments out to the end of the line in the usual way (backslash it for a literal). Leading and trailing whitespace is trimmed off. Lines may be continued with a "\\" as the last character of a line (it becomes a space character). .PP .SH OPTIONS .PP \fB-display\fR \fIdisp\fR .IP X11 server display to connect to, usually :0. The X server process must be running on same machine and support MIT-SHM. Equivalent to setting the DISPLAY environment variable to \fIdisp\fR. .IP See the description below of the "\fB-display\fR \fIWAIT:...\fR" extensions, where alias "\fB-find\fR" will find the user's display automatically, and "\fB-create\fR" will create a Xvfb session if no session is found. .PP \fB-auth\fR \fIfile\fR .IP Set the X authority file to be \fIfile\fR, equivalent to setting the XAUTHORITY environment variable to \fIfile\fR before startup. Same as \fB-xauth\fR file. See .IR Xsecurity (7) , .IR xauth (1) man pages for more info. .IP Use '-auth guess' to have x11vnc use its \fB-findauth\fR mechanism (described below) to try to guess the XAUTHORITY filename and use it. .IP XDM/GDM/KDM: if you are running x11vnc as root and want to find the XAUTHORITY before anyone has logged into an X session yet, use: x11vnc \fB-env\fR FD_XDM=1 \fB-auth\fR guess ... (This will also find the XAUTHORITY if a user is already logged into the X session.) When running as root, FD_XDM=1 will be tried if the initial \fB-auth\fR guess fails. .PP \fB-N\fR .IP If the X display is :N, try to set the VNC display to also be :N This just sets the \fB-rfbport\fR option to 5900+N The program will exit immediately if that port is not available. The \fB-N\fR option only works with normal \fB-display\fR usage, e.g. :0 or :8, \fB-N\fR is ignored in the \fB-display\fR WAIT:..., \fB-create,\fR \fB-find,\fR \fB-svc,\fR \fB-redirect,\fR etc modes. .PP \fB-autoport\fR \fIn\fR .IP Automatically probe for a free VNC port starting at n. The default is to start probing at 5900. Use this to stay away from other VNC servers near 5900. .PP \fB-rfbport\fR \fIstr\fR .IP The VNC port to listen on (a LibVNCServer option), e.g. 5900, 5901, etc. If specified as "\fB-rfbport\fR \fIPROMPT\fR" then the x11vnc \fB-gui\fR is used to prompt the user to enter the port number. .PP \fB-6\fR .IP IPv6 listening support. In addition to IPv4, the IPv6 address is listened on for incoming connections. The same port number as IPv4 is used. .IP NOTE: This x11vnc binary was compiled to have the "-6" IPv6 listening mode ENABLED by default (CPPFLAGS \fB-DX11VNC_LISTEN6=1).\fR So to disable IPv6 listening mode you MUST supply the "\fB-no6\fR" option (see below.) .IP The "-6" mode works for both normal connections and \fB-ssl\fR encrypted ones. Nearly everything is supported for the IPv6 case, but there are a few exceptions. See \fB-stunnel\fR for its IPv6 support. .IP Currently, for absolutely everything to work correctly the machine may need to have some IPv4 support, at the least for the loopback interface. However, for nearly all usage modes no IPv4 support is required. See \fB-noipv4.\fR .IP If you have trouble compiling or running in IPv6 mode, set \fB-DX11VNC_IPV6=0\fR in CPPFLAGS when configuring to disable IPv6 support. .PP \fB-no6\fR .IP Disable IPv6 listening support (only useful if the "-6" mode is compiled in to be the default; see the X11VNC_LISTEN6 description above under "-6".) .PP \fB-noipv6\fR .IP Do not try to use IPv6 for any listening or connecting sockets. This includes both the listening service port(s) and outgoing connections from \fB-connect,\fR \fB-connect_or_exit,\fR or \fB-proxy.\fR Use this if you are having problems due to IPv6. .PP \fB-noipv4\fR .IP Do not try to use IPv4 for any listening or connecting sockets. This is mainly for exploring the behavior of x11vnc on an IPv6-only system, but may have other uses. .PP \fB-reopen\fR .IP If the X server connection is disconnected, try to reopen the X display (up to one time.) This is of use for display managers like GDM (KillInitClients option) that kill x11vnc just after the user logs into the X session. Note: the reopened state may be unstable. Set X11VNC_REOPEN_DISPLAY=n to reopen n times and set X11VNC_REOPEN_SLEEP_MAX to the number of seconds, default 10, to keep trying to reopen the display (once per second.) .IP Update: as of 0.9.9, x11vnc tries to automatically avoid being killed by the display manager by delaying creating windows or using XFIXES. So you shouldn't need to use KillInitClients=false as long as you log in quickly enough (within 45 seconds of connecting.) You can disable this by setting X11VNC_AVOID_WINDOWS=never. You can also set it to the number of seconds to delay. .PP \fB-reflect\fR \fIhost:N\fR .IP Instead of connecting to and polling an X display, connect to the remote VNC server host:N and be a reflector/repeater for it. This is useful for trying to manage the case of many simultaneous VNC viewers (e.g. classroom broadcasting) where, e.g. you put a repeater on each network switch, etc, to improve performance by distributing the load and network traffic. Implies \fB-shared\fR (use \fB-noshared\fR as a later option to disable). See the discussion below under \fB-rawfb\fR vnc:host:N for more details. .PP \fB-id\fR \fIwindowid\fR .IP Show the X window corresponding to \fIwindowid\fR not the entire display. New windows like popup menus, transient toplevels, etc, may not be seen or may be clipped. Disabling SaveUnders or BackingStore in the X server may help show them. x11vnc may crash if the window is initially partially obscured, changes size, is iconified, etc. Some steps are taken to avoid this and the \fB-xrandr\fR mechanism is used to track resizes. Use .IR xwininfo (1) to get the window id, or use "\fB-id\fR \fIpick\fR" to have x11vnc run .IR xwininfo (1) for you and extract the id. The \fB-id\fR option is useful for exporting very simple applications (e.g. the current view on a webcam). .PP \fB-sid\fR \fIwindowid\fR .IP As \fB-id,\fR but instead of using the window directly it shifts a root view to it: this shows SaveUnders menus, etc, although they will be clipped if they extend beyond the window. .PP \fB-appshare\fR .IP Simple application sharing based on the \fB-id/-sid\fR mechanism. Every new toplevel window that the application creates induces a new viewer window via a reverse connection. The \fB-id/-sid\fR and \fB-connect\fR options are required. Run 'x11vnc \fB-appshare\fR \fB-help'\fR for more info. .PP \fB-clip\fR \fIWxH+X+Y\fR .IP Only show the sub-region of the full display that corresponds to the rectangle geometry with size WxH and offset +X+Y. The VNC display has size WxH (i.e. smaller than the full display). This also works for \fB-id/-sid\fR mode where the offset is relative to the upper left corner of the selected window. An example use of this option would be to split a large (e.g. Xinerama) display into two parts to be accessed via separate viewers by running a separate x11vnc on each part. .IP Use '-clip xinerama0' to clip to the first xinerama sub-screen (if xinerama is active). xinerama1 for the 2nd sub-screen, etc. This way you don't need to figure out the WxH+X+Y of the desired xinerama sub-screen. screens are sorted in increasing distance from the (0,0) origin (I.e. not the Xserver's order). .PP \fB-flashcmap\fR .IP In 8bpp indexed color, let the installed colormap flash as the pointer moves from window to window (slow). Also try the \fB-8to24\fR option to avoid flash altogether. .PP \fB-shiftcmap\fR \fIn\fR .IP Rare problem, but some 8bpp displays use less than 256 colorcells (e.g. 16-color grayscale, perhaps the other bits are used for double buffering) *and* also need to shift the pixels values away from 0, .., ncells. \fIn\fR indicates the shift to be applied to the pixel values. To see the pixel values set DEBUG_CMAP=1 to print out a colormap histogram. Example: \fB-shiftcmap\fR 240 .PP \fB-notruecolor\fR .IP For 8bpp displays, force indexed color (i.e. a colormap) even if it looks like 8bpp TrueColor (rare problem). .PP \fB-advertise_truecolor\fR .IP If the X11 display is indexed color, lie to clients when they first connect by telling them it is truecolor. To workaround RealVNC: inPF has colourMap but not 8bpp Use '-advertise_truecolor reset' to reset client fb too. .PP \fB-visual\fR \fIn\fR .IP This option probably does not do what you think. It simply *forces* the visual used for the framebuffer; this may be a bad thing... (e.g. messes up colors or cause a crash). It is useful for testing and for some workarounds. n may be a decimal number, or 0x hex. Run .IR xdpyinfo (1) for the values. One may also use "TrueColor", etc. see <X11/X.h> for a list. If the string ends in ":m" then for better or for worse the visual depth is forced to be m. You may want to use \fB-noshm\fR when using this option (so XGetImage may automatically translate the pixel data). .PP \fB-overlay\fR .IP Handle multiple depth visuals on one screen, e.g. 8+24 and 24+8 overlay visuals (the 32 bits per pixel are packed with 8 for PseudoColor and 24 for TrueColor). .IP Currently \fB-overlay\fR only works on Solaris via .IR XReadScreen (3X11) and IRIX using .IR XReadDisplay (3). On Solaris there is a problem with image "bleeding" around transient popup menus (but not for the menu itself): a workaround is to disable SaveUnders by passing the "\fB-su\fR" argument to Xsun (in /etc/dt/config/Xservers). .IP Use \fB-overlay\fR as a workaround for situations like these: Some legacy applications require the default visual to be 8bpp (8+24), or they will use 8bpp PseudoColor even when the default visual is depth 24 TrueColor (24+8). In these cases colors in some windows will be incorrect in x11vnc unless \fB-overlay\fR is used. Another use of \fB-overlay\fR is to enable showing the exact mouse cursor shape (details below). .IP Under \fB-overlay,\fR performance will be somewhat slower due to the extra image transformations required. For optimal performance do not use \fB-overlay,\fR but rather configure the X server so that the default visual is depth 24 TrueColor and try to have all apps use that visual (e.g. some apps have \fB-use24\fR or \fB-visual\fR options). .PP \fB-overlay_nocursor\fR .IP Sets \fB-overlay,\fR but does not try to draw the exact mouse cursor shape using the overlay mechanism. .PP \fB-8to24\fR \fI[opts]\fR .IP Try this option if \fB-overlay\fR is not supported on your OS, and you have a legacy 8bpp app that you want to view on a multi-depth display with default depth 24 (and is 32 bpp) OR have a default depth 8 display with depth 24 overlay windows for some apps. This option may not work on all X servers and hardware (tested on XFree86/Xorg mga driver and Xsun). The "opts" string is not required and is described below. .IP This mode enables a hack where x11vnc monitors windows within 3 levels from the root window. If it finds any that are 8bpp it extracts the indexed color pixel values using XGetImage() and then applies a transformation using the colormap(s) to create TrueColor RGB values that it in turn inserts into bits 1-24 of the framebuffer. This creates a depth 24 "view" of the display that is then exported via VNC. .IP Conversely, for default depth 8 displays, the depth 24 regions are read by XGetImage() and everything is transformed and inserted into a depth 24 TrueColor framebuffer. .IP Note that even if there are *no* depth 24 visuals or windows (i.e. pure 8bpp), this mode is potentially an improvement over \fB-flashcmap\fR because it avoids the flashing and shows each window in the correct color. .IP This method works OK, but may still have bugs and it does hog resources. If there are multiple 8bpp windows using different colormaps, one may have to iconify all but one for the colors to be correct. .IP There may be painting errors for clipping and switching between windows of depths 8 and 24. Heuristics are applied to try to minimize the painting errors. One can also press 3 Alt_L's in a row to refresh the screen if the error does not repair itself. Also the option \fB-fixscreen\fR 8=3.0 or \fB-fixscreen\fR V=3.0 may be used to periodically refresh the screen at the cost of bandwidth (every 3 sec for this example). .IP The [opts] string can contain the following settings. Multiple settings are separated by commas. .IP For for some X servers with default depth 24 a speedup may be achieved via the option "nogetimage". This enables a scheme were XGetImage() is not used to retrieve the 8bpp data. Instead, it assumes that the 8bpp data is in bits 25-32 of the 32bit X pixels. There is no requirement that the X server should put the data there for our poll requests, but some do and so the extra steps to retrieve it can be skipped. Tested with mga driver with XFree86/Xorg. For the default depth 8 case this option is ignored. .IP To adjust how often XGetImage() is used to poll the non-default visual regions for changes, use the option "poll=t" where "t" is a floating point time. (default: 0.05) .IP Setting the option "level2" will limit the search for non-default visual windows to two levels from the root window. Do this on slow machines where you know the window manager only imposes one extra window between the app window and the root window. .IP Also for very slow machines use "cachewin=t" where t is a floating point amount of time to cache XGetWindowAttributes results. E.g. cachewin=5.0. This may lead to the windows being unnoticed for this amount of time when deiconifying, painting errors, etc. .IP While testing on a very old SS20 these options gave tolerable response: \fB-8to24\fR poll=0.2,cachewin=5.0. For this machine \fB-overlay\fR is supported and gives better response. .IP Debugging for this mode can be enabled by setting "dbg=1", "dbg=2", or "dbg=3". .PP \fB-24to32\fR .IP Very rare problem: if the framebuffer (X display or \fB-rawfb)\fR is 24bpp instead of the usual 32bpp, then dynamically transform the pixels to 32bpp. This will be slower, but can be used to work around problems where VNC viewers cannot handle 24bpp (e.g. "main: setPF: not 8, 16 or 32 bpp?"). See the FAQ for more info. .IP In the case of \fB-rawfb\fR mode, the pixels are directly modified by inserting a 0 byte to pad them out to 32bpp. For X displays, a kludge is done that is equivalent to "\fB-noshm\fR \fI\fB-visual\fR TrueColor:32\fR". (If better performance is needed for the latter, feel free to ask). .PP \fB-scale\fR \fIfraction\fR .IP Scale the framebuffer by factor \fIfraction\fR. Values less than 1 shrink the fb, larger ones expand it. Note: the image may not be sharp and response may be slower. If \fIfraction\fR contains a decimal point "." it is taken as a floating point number, alternatively the notation "m/n" may be used to denote fractions exactly, e.g. \fB-scale\fR 2/3 .IP To scale asymmetrically in the horizontal and vertical directions, specify a WxH geometry to stretch to: e.g. '-scale 1024x768', or also '-scale 0.9x0.75' .IP Scaling Options: can be added after \fIfraction\fR via ":", to supply multiple ":" options use commas. If you just want a quick, rough scaling without blending, append ":nb" to \fIfraction\fR (e.g. \fB-scale\fR 1/3:nb). No blending is the default for 8bpp indexed color, to force blending for this case use ":fb". .IP To disable \fB-scrollcopyrect\fR and \fB-wirecopyrect\fR under \fB-scale\fR use ":nocr". If you need to to enable them use ":cr" or specify them explicitly on the command line. If a slow link is detected, ":nocr" may be applied automatically. Default: :cr .IP More esoteric options: for compatibility with vncviewers the scaled width is adjusted to be a multiple of 4: to disable this use ":n4". ":in" use interpolation scheme even when shrinking, ":pad" pad scaled width and height to be multiples of scaling denominator (e.g. 3 for 2/3). .PP \fB-geometry\fR \fIWxH\fR .IP Same as \fB-scale\fR WxH .PP \fB-scale_cursor\fR \fIfrac\fR .IP By default if \fB-scale\fR is supplied the cursor shape is scaled by the same factor. Depending on your usage, you may want to scale the cursor independently of the screen or not at all. If you specify \fB-scale_cursor\fR the cursor will be scaled by that factor. When using \fB-scale\fR mode to keep the cursor at its "natural" size use "\fB-scale_cursor\fR \fI1\fR". Most of the ":" scaling options apply here as well. .PP \fB-viewonly\fR .IP All VNC clients can only watch (default off). .PP \fB-shared\fR .IP VNC display is shared, i.e. more than one viewer can connect at the same time (default off). .PP \fB-once\fR .IP Exit after the first successfully connected viewer disconnects, opposite of \fB-forever.\fR This is the Default. .PP \fB-forever\fR .IP Keep listening for more connections rather than exiting as soon as the first client(s) disconnect. Same as \fB-many\fR .IP To get the standard non-shared VNC behavior where when a new VNC client connects the existing VNC client is dropped use: \fB-nevershared\fR \fB-forever\fR This method can also be used to guard against hung TCP connections that do not go away. .PP \fB-loop\fR .IP Create an outer loop restarting the x11vnc process whenever it terminates. \fB-bg\fR and \fB-inetd\fR are ignored in this mode (however see \fB-loopbg\fR below). .IP Useful for continuing even if the X server terminates and restarts (at that moment the process will need permission to reconnect to the new X server of course). .IP Use, e.g., \fB-loop100\fR to sleep 100 millisecs between restarts, etc. Default is 2000ms (i.e. 2 secs) Use, e.g. \fB-loop300,5\fR to sleep 300 ms and only loop 5 times. .IP If \fB-loopbg\fR (plus any numbers) is specified instead, the "\fB-bg\fR" option is implied and the mode approximates .IR inetd (8) usage to some degree. In this case when it goes into the background any listening sockets (i.e. ports 5900, 5800) are closed, so the next one in the loop can use them. This mode will only be of use if a VNC client (the only client for that process) is already connected before the process goes into the background, for example, usage of \fB-display\fR WAIT:.., \fB-svc,\fR and \fB-connect\fR can make use of this "poor man's" inetd mode. The default wait time is 500ms in this mode. This usage could use useful: \fB-svc\fR \fB-bg\fR \fB-loopbg\fR .PP \fB-timeout\fR \fIn\fR .IP Exit unless a client connects within the first n seconds after startup. .IP If there have been no connection attempts after n seconds x11vnc exits immediately. If a client is trying to connect but has not progressed to the normal operating state, x11vnc gives it a few more seconds to finish and exits if it does not make it to the normal state. .IP For reverse connections via \fB-connect\fR or \fB-connect_or_exit\fR a timeout of n seconds will be set for all reverse connects. If the connect timeout alarm goes off, x11vnc will exit immediately. .PP \fB-sleepin\fR \fIn\fR .IP At startup sleep n seconds before proceeding (e.g. to allow redirs and listening clients to start up) .IP If a range is given: '-sleepin min-max', a random value between min and max is slept. E.g. '-sleepin 0-20' and \(aq-sleepin 10-30\(aq. Floats are allowed too. .PP \fB-inetd\fR .IP Launched by .IR inetd (8): stdio instead of listening socket. Note: if you are not redirecting stderr to a log file (via shell 2> or \fB-o\fR option) you MUST also specify the \fB-q\fR option, otherwise the stderr goes to the viewer which will cause it to abort. Specifying both \fB-inetd\fR and \fB-q\fR and no \fB-o\fR will automatically close the stderr. .PP \fB-tightfilexfer\fR .IP Enable the TightVNC file transfer extension. Note that that when the \fB-viewonly\fR option is supplied all file transfers are disabled. Also clients that log in viewonly cannot transfer files. However, if the remote control mechanism is used to change the global or per-client viewonly state the filetransfer permissions will NOT change. .IP IMPORTANT: please understand if \fB-tightfilexfer\fR is specified and you run x11vnc as root for, say, inetd or display manager (gdm, kdm, ...) access and you do not have it switch users via the \fB-users\fR option, then VNC Viewers that connect are able to do filetransfer reads and writes as *root*. .IP Also, tightfilexfer is disabled in \fB-unixpw\fR mode. .PP \fB-ultrafilexfer\fR .IP Note: to enable UltraVNC filetransfer and to get it to work you probably need to supply these LibVNCServer options: "\fB-rfbversion\fR \fI3.6 \fB-permitfiletransfer\fR"\fR "\fB-ultrafilexfer\fR" is an alias for this combination. .IP IMPORTANT: please understand if \fB-ultrafilexfer\fR is specified and you run x11vnc as root for, say, inetd or display manager (gdm, kdm, ...) access and you do not have it switch users via the \fB-users\fR option, then VNC Viewers that connect are able to do filetransfer reads and writes as *root*. .IP Note that sadly you cannot do both \fB-tightfilexfer\fR and \fB-ultrafilexfer\fR at the same time because the latter requires setting the version to 3.6 and tightvnc will not do filetransfer when it sees that version number. .PP \fB-http\fR .IP Instead of using \fB-httpdir\fR (see below) to specify where the Java vncviewer applet is, have x11vnc try to *guess* where the directory is by looking relative to the program location and in standard locations (/usr/local/share/x11vnc/classes, etc). Under \fB-ssl\fR or \fB-stunnel\fR the ssl classes subdirectory is sought. .PP \fB-http_ssl\fR .IP As \fB-http,\fR but force lookup for ssl classes subdir. .IP Note that for HTTPS, single-port Java applet delivery you can set X11VNC_HTTPS_DOWNLOAD_WAIT_TIME to the max number of seconds to wait for the applet download to finish. The default is 15. .PP \fB-avahi\fR .IP Use the Avahi/mDNS ZeroConf protocol to advertise this VNC server to the local network. (Related terms: Rendezvous, Bonjour). Depending on your setup, you may need to start avahi-daemon and open udp port 5353 in your firewall. .IP You can set X11VNC_AVAHI_NAME, X11VNC_AVAHI_HOST, and/or X11VNC_AVAHI_PORT environment variables to override the default values. For example: \fB-env\fR X11VNC_AVAHI_NAME=wally .IP If the avahi API cannot be found at build time, a helper program like avahi- .IR publish (1) or dns- .IR sd (1) will be tried .PP \fB-mdns\fR .IP Same as \fB-avahi.\fR .PP \fB-zeroconf\fR .IP Same as \fB-avahi.\fR .PP \fB-connect\fR \fIstring\fR .IP For use with "vncviewer -listen" reverse connections. If \fIstring\fR has the form "host" or "host:port" the connection is made once at startup. .IP Use commas for a list of host's and host:port's. E.g. \fB-connect\fR host1,host2 or host1:0,host2:5678. Note that to reverse connect to multiple hosts at the same time you will likely need to also supply: \fB-shared\fR .IP Note that unlike most vnc servers, x11vnc will require a password for reverse as well as for forward connections. (provided password auth has been enabled, \fB-rfbauth,\fR etc) If you do not want to require a password for reverse connections set X11VNC_REVERSE_CONNECTION_NO_AUTH=1 in your environment before starting x11vnc. .IP If \fIstring\fR contains "/" it is instead interpreted as a file to periodically check for new hosts. The first line is read and then the file is truncated. Be careful about the location of this file if x11vnc is running as root (e.g. via .IR gdm (1) , etc). .IP Repeater mode: Some services provide an intermediate "vnc repeater": http://www.uvnc.com/addons/repeater.html (and also http://koti.mbnet.fi/jtko/ for linux port) that acts as a proxy/gateway. Modes like these require an initial string to be sent for the reverse connection before the VNC protocol is started. Here are the ways to do this: .IP \fB-connect\fR pre=some_string+host:port \fB-connect\fR pre128=some_string+host:port \fB-connect\fR repeater=ID:1234+host:port \fB-connect\fR repeater=23.45.67.89::5501+host:port .IP SSVNC notation is also supported: .IP \fB-connect\fR repeater://host:port+ID:1234 .IP As with normal \fB-connect\fR usage, if the repeater port is not supplied 5500 is assumed. .IP The basic idea is between the special tag, e.g. "pre=" and "+" is the pre-string to be sent. Note that in this case host:port is the repeater server, NOT the vnc viewer. Somehow the pre-string tells the repeater server how to find the vnc viewer and connect you to it. .IP In the case pre=some_string+host:port, "some_string" is simply sent. In the case preNNN=some_string+host:port "some_string" is sent in a null padded buffer of length NNN. repeater= is the same as pre250=, this is the ultravnc repeater buffer size. .IP Strings like "\\n" and "\\r", etc. are expanded to newline and carriage return. "\\c" is expanded to "," since the connect string is comma separated. .IP See also the \fB-proxy\fR option below for additional ways to plumb reverse connections. .IP Reverse SSL: using \fB-connect\fR in \fB-ssl\fR mode makes x11vnc act as an SSL client (initiates SSL connection) rather than an SSL server. The idea is x11vnc might be connecting to stunnel on the viewer side with the viewer in listening mode. If you do not want this behavior, use \fB-env\fR X11VNC_DISABLE_SSL_CLIENT_MODE=1. With this the viewer side can act as the SSL client as it normally does for forward connections. .IP Reverse SSL Repeater mode: This will work, but note that if the VNC Client does any sort of a 'Fetch Cert' action before connecting, then the Repeater will likely drop the connection and both sides will need to restart. Consider the use of \fB-connect_or_exit\fR and \fB-loop300,2\fR to have x11vnc reconnect once to the repeater after the fetch. You will probably also want to supply \fB-sslonly\fR to avoid x11vnc thinking the delay in response means the connection is VeNCrypt. The env var X11VNC_DISABLE_SSL_CLIENT_MODE=1 discussed above may also be useful (i.e. the viewer can do a forward connection as it normally does.) .IP IPv6: as of x11vnc 0.9.10 the \fB-connect\fR option should connect to IPv6 hosts properly. If there are problems you can disable IPv6 by setting \fB-DX11VNC_IPV6=0\fR in CPPFLAGS when configuring. If there problems connecting to IPv6 hosts consider a relay like the included inet6to4 script or the \fB-proxy\fR option. .PP \fB-connect_or_exit\fR \fIstr\fR .IP As with \fB-connect,\fR except if none of the reverse connections succeed, then x11vnc shuts down immediately .IP An easier to type alias for this option is '-coe' .IP By the way, if you do not want x11vnc to listen on ANY interface use \fB-rfbport\fR 0 which is handy for the \fB-connect_or_exit\fR mode. .PP \fB-proxy\fR \fIstring\fR .IP Use proxy in string (e.g. host:port) as a proxy for making reverse connections (-connect or \fB-connect_or_exit\fR options). .IP Web proxies are supported, but note by default most of them only support destination connections to ports 443 or 563, so this might not be very useful (the viewer would need to listen on that port or the router would have to do a port redirection). .IP A web proxy may be specified by either "host:port" or "http://host:port" (the port is required even if it is the common choices 80 or 8080) .IP SOCKS4, SOCKS4a, and SOCKS5 are also supported. SOCKS proxies normally do not have restrictions on the destination port number. .IP Use a format like this: socks://host:port or socks5://host:port. Note that ssh \fB-D\fR does not support SOCKS4a, so use socks5://. For socks:// SOCKS4 is used on a numerical IP and "localhost", otherwise SOCKS4a is used (and so the proxy tries to do the DNS lookup). .IP An experimental mode is "\fB-proxy\fR \fIhttp://host:port/...\fR" Note the "/" after the port that distinguishes it from a normal web proxy. The port must be supplied even if it is the default 80. For this mode a GET is done to the supplied URL with the string host=H&port=P appended. H and P will be the \fB-connect\fR reverse connect host and port. Use the string "__END__" to disable the appending. The basic idea here is that maybe some cgi script provides the actual viewer hookup and tunnelling. How to actually achieve this within cgi, php, etc. is not clear... A custom web server or apache module would be straight-forward. .IP Another experimental mode is "\fB-proxy\fR \fIssh://user@host\fR" in which case a SSH tunnel is used for the proxying. "user@" is not needed unless your unix username is different on "host". For a non-standard SSH port use ssh://user@host:port. If proxies are chained (see next paragraph) then the ssh one must be the first one. If ssh-agent is not active, then the ssh password needs to be entered in the terminal where x11vnc is running. Examples: .IP \fB-connect\fR localhost:0 \fB-proxy\fR ssh://me@friends-pc:2222 .IP \fB-connect\fR snoopy:0 \fB-proxy\fR ssh://ssh.company.com .IP Multiple proxies may be chained together in case one needs to ricochet off of a number of hosts to finally reach the VNC viewer. Up to 3 may be chained, separate them by commas in the order they are to be connected to. E.g.: http://host1:port1,socks5://host2:port2 or three like: first,second,third .IP IPv6: as of x11vnc 0.9.10 the \fB-proxy\fR option should connect to IPv6 hosts properly. If there are problems you can disable IPv6 by setting \fB-DX11VNC_IPV6=0\fR in CPPFLAGS when configuring. If there problems connecting to IPv6 hosts consider a relay like the included inet6to4 script. .PP \fB-vncconnect,\fR \fB-novncconnect\fR .IP Monitor the VNC_CONNECT X property set by the standard VNC program .IR vncconnect (1). When the property is set to "host" or "host:port" establish a reverse connection. Using .IR xprop (1) instead of vncconnect may work (see the FAQ). The \fB-remote\fR control mechanism uses X11VNC_REMOTE channel, and this option disables/enables it as well. Default: \fB-vncconnect\fR .IP To use different names for these X11 properties (e.g. to have separate communication channels for multiple x11vnc's on the same display) set the VNC_CONNECT or X11VNC_REMOTE env. vars. to the string you want, for example: \fB-env\fR X11VNC_REMOTE=X11VNC_REMOTE_12345 Both sides of the channel must use the same unique name. The same can be done for the internal X11VNC_TICKER property (heartbeat and timestamp) if desired. .PP \fB-allow\fR \fIhost1[,host2..]\fR .IP Only allow client connections from hosts matching the comma separated list of hostnames or IP addresses. Can also be a numerical IP prefix, e.g. "192.168.100." to match a simple subnet, for more control build LibVNCServer with libwrap support (See the FAQ). If the list contains a "/" it instead is a interpreted as a file containing addresses or prefixes that is re-read each time a new client connects. Lines can be commented out with the "#" character in the usual way. .IP \fB-allow\fR applies in \fB-ssl\fR mode, but not in \fB-stunnel\fR mode. .IP IPv6: as of x11vnc 0.9.10 a host can be specified in IPv6 numerical format, e.g. 2001:4860:b009::93. .PP \fB-localhost\fR .IP Basically the same as "\fB-allow\fR \fI127.0.0.1\fR". .IP Note: if you want to restrict which network interface x11vnc listens on, see the \fB-listen\fR option below. E.g. "\fB-listen\fR \fIlocalhost\fR" or "\fB-listen\fR \fI192.168.3.21\fR". As a special case, the option "\fB-localhost\fR" implies "\fB-listen\fR \fIlocalhost\fR". .IP A rare case, but for non-localhost \fB-listen\fR usage, if you use the remote control mechanism (-R) to change the \fB-listen\fR interface you may need to manually adjust the \fB-allow\fR list (and vice versa) to avoid situations where no connections (or too many) are allowed. .IP If you do not want x11vnc to listen on ANY interface (evidently you are using \fB-connect\fR or \fB-connect_or_exit,\fR or plan to use remote control: \fB-R\fR connect:host), use \fB-rfbport\fR 0 .IP IPv6: if IPv6 is supported, this option automatically implies the IPv6 loopback address '::1' as well. .PP \fB-unixsock\fR \fIstr\fR .IP Listen on the unix socket (AF_UNIX) 'str' for connections. This mode is for either local connections or a tunnel endpoint where one wants the file permission of the unix socket file to determine what can connect to it. (This currently requires an edit to libvnserver/rfbserver.c: comment out lines 310 and 311, 'close(sock)' and 'return NULL' in rfbserver.c after the setsockopt() call.) Note that to disable all tcp listening ports specify '-rfbport 0' and should be useful with this mode. Example: mkdir ~/s; chmod 700 ~/s; x11vnc \fB-unixsock\fR ~/s/mysock \fB-rfbport\fR 0 ... The SSVNC unix vncviewer can connect to unix sockets. .PP \fB-listen6\fR \fIstr\fR .IP When in IPv6 listen mode "-6", listen only on the network interface with address \fIstr\fR. It also works for link scope addresses (fe80::219:dbff:fee5:3f92%eth0) and IPv6 hostname strings (e.g. ipv6.google.com.) Use LibVNCServer \fB-listen\fR option for the IPv4 interface. .PP \fB-nolookup\fR .IP Do not use gethostbyname() or gethostbyaddr() to look up host names or IP numbers. Use this if name resolution is incorrectly set up and leads to long pauses as name lookups time out, etc. .PP \fB-input\fR \fIstring\fR .IP Fine tuning of allowed user input. If \fIstring\fR does not contain a comma "," the tuning applies only to normal clients. Otherwise the part before "," is for normal clients and the part after for view-only clients. "K" is for Keystroke input, "M" for Mouse-motion input, "B" for Button-click input, "C" is for Clipboard input, and "F" is for File transfer (ultravnc only). Their presence in the string enables that type of input. E.g. "\fB-input\fR \fIM\fR" means normal users can only move the mouse and "\fB-input\fR \fIKMBCF,M\fR" lets normal users do anything and enables view-only users to move the mouse. This option is ignored when a global \fB-viewonly\fR is in effect (all input is discarded in that case). .PP \fB-grabkbd\fR .IP When VNC viewers are connected, attempt to the grab the keyboard so a (non-malicious) user sitting at the physical display is not able to enter keystrokes. This method uses .IR XGrabKeyboard (3X11) and so it is not secure and does not rule out the person at the physical display injecting keystrokes by flooding the server with them, grabbing the keyboard himself, etc. Some degree of cooperation from the person at the display is assumed. This is intended for remote help-desk or educational usage modes. .IP Note: on some recent (12/2010) X servers and/or desktops, \fB-grabkbd\fR no longer works: it prevents the window manager from resizing windows and similar things. Try \fB-ungrabboth\fR below (might not work.) .PP \fB-grabptr\fR .IP As \fB-grabkbd,\fR but for the mouse pointer using .IR XGrabPointer (3X11). Unfortunately due to the way the X server works, the mouse can still be moved around by the user at the physical display, but he will not be able to change window focus with it. Also some window managers that call .IR XGrabServer (3X11) for resizes, etc, will act on the local user's input. Again, some degree of cooperation from the person at the display is assumed. .PP \fB-ungrabboth\fR .IP Whenever there is any input (either keyboard or pointer), ungrab *both* the keyboard and the pointer while injecting the synthetic input. This is to allow window managers, etc. a chance to grab. .PP \fB-grabalways\fR .IP Apply both \fB-grabkbd\fR and \fB-grabptr\fR even when no VNC viewers are connected. If you only want one of them, use the \fB-R\fR remote control to turn the other back on, e.g. \fB-R\fR nograbptr. .PP \fB-viewpasswd\fR \fIstring\fR .IP Supply a 2nd password for view-only logins. The \fB-passwd\fR (full-access) password must also be supplied. .PP \fB-passwdfile\fR \fIfilename\fR .IP Specify the LibVNCServer password via the first line of the file \fIfilename\fR (instead of via \fB-passwd\fR on the command line where others might see it via .IR ps (1) ). .IP See the descriptions below for how to supply multiple passwords, view-only passwords, to specify external programs for the authentication, and other features. .IP If the filename is prefixed with "rm:" it will be removed after being read. Perhaps this is useful in limiting the readability of the file. In general, the password file should not be readable by untrusted users (BTW: neither should the VNC \fB-rfbauth\fR file: it is NOT encrypted, only obscured with a fixed key). .IP If the filename is prefixed with "read:" it will periodically be checked for changes and reread. It is guaranteed to be reread just when a new client connects so that the latest passwords will be used. .IP If \fIfilename\fR is prefixed with "cmd:" then the string after the ":" is run as an external command: the output of the command will be interpreted as if it were read from a password file (see below). If the command does not exit with 0, then x11vnc terminates immediately. To specify more than 1000 passwords this way set X11VNC_MAX_PASSWDS before starting x11vnc. The environment variables are set as in \fB-accept.\fR .IP Note that due to the VNC protocol only the first 8 characters of a password are used (DES key). .IP If \fIfilename\fR is prefixed with "custom:" then a custom password checker is supplied as an external command following the ":". The command will be run when a client authenticates. If the command exits with 0 the client is accepted, otherwise it is rejected. The environment variables are set as in \fB-accept.\fR .IP The standard input to the custom command will be a decimal digit "len" followed by a newline. "len" specifies the challenge size and is usually 16 (the VNC spec). Then follows len bytes which is the random challenge string that was sent to the client. This is then followed by len more bytes holding the client's response (i.e. the challenge string encrypted via DES with the user password in the standard situation). .IP The "custom:" scheme can be useful to implement dynamic passwords or to implement methods where longer passwords and/or different encryption algorithms are used. The latter will require customizing the VNC client as well. One could create an MD5SUM based scheme for example. .IP File format for \fB-passwdfile:\fR .IP If multiple non-blank lines exist in the file they are all taken as valid passwords. Blank lines are ignored. Password lines may be "commented out" (ignored) if they begin with the character "#" or the line contains the string "__SKIP__". Lines may be annotated by use of the "__COMM__" string: from it to the end of the line is ignored. An empty password may be specified via the "__EMPTY__" string on a line by itself (note your viewer might not accept empty passwords). .IP If the string "__BEGIN_VIEWONLY__" appears on a line by itself, the remaining passwords are used for viewonly access. For compatibility, as a special case if the file contains only two password lines the 2nd one is automatically taken as the viewonly password. Otherwise the "__BEGIN_VIEWONLY__" token must be used to have viewonly passwords. (tip: make the 3rd and last line be "__BEGIN_VIEWONLY__" to have 2 full-access passwords) .PP \fB-showrfbauth\fR \fIfilename\fR .IP Print to the screen the obscured VNC password kept in the rfbauth file \fIfilename\fR and then exit. .PP \fB-unixpw\fR \fI[list]\fR .IP Use Unix username and password authentication. x11vnc will use the .IR su (1) program to verify the user's password. [list] is an optional comma separated list of allowed Unix usernames. If the [list] string begins with the character "!" then the entire list is taken as an exclude list. See below for per-user options that can be applied. .IP A familiar "login:" and "Password:" dialog is presented to the user on a black screen inside the vncviewer. The connection is dropped if the user fails to supply the correct password in 3 tries or does not send one before a 45 second timeout. Existing clients are view-only during this period. .IP If the first character received is "Escape" then the unix username will not be displayed after "login:" as it is typed. This could be of use for VNC viewers that automatically type the username and password. .IP Since the detailed behavior of .IR su (1) can vary from OS to OS and for local configurations, test the mode before deployment to make sure it is working properly. x11vnc will attempt to be conservative and reject a login if anything abnormal occurs. .IP One case to note: FreeBSD and the other BSD's by default it is impossible for the user running x11vnc to validate his *own* password via .IR su (1) (commenting out the pam_self.so entry in /etc/pam.d/su eliminates this behavior). So the x11vnc login will always *FAIL* for this case (even when the correct password is supplied). .IP A possible workaround for this on *BSD would be to start x11vnc as root with the "\fB-users\fR \fI+nobody\fR" option to immediately switch to user nobody where the su'ing will proceed normally. .IP Another source of potential problems are PAM modules that prompt for extra info, e.g. password aging modules. These logins will fail as well even when the correct password is supplied. .IP **IMPORTANT**: to prevent the Unix password being sent in *clear text* over the network, one of two schemes will be enforced: 1) the \fB-ssl\fR builtin SSL mode, or 2) require both \fB-localhost\fR and \fB-stunnel\fR be enabled. .IP Method 1) ensures the traffic is encrypted between viewer and server. A PEM file will be required, see the discussion under \fB-ssl\fR below (under some circumstances a temporary one can be automatically generated). .IP Method 2) requires the viewer connection to appear to come from the same machine x11vnc is running on (e.g. from a ssh \fB-L\fR port redirection). And that the \fB-stunnel\fR SSL mode be used for encryption over the network. (see the description of \fB-stunnel\fR below). .IP Note: as a convenience, if you .IR ssh (1) in and start x11vnc it will check if the environment variable SSH_CONNECTION is set and appears reasonable. If it does, then the \fB-ssl\fR or \fB-stunnel\fR requirement will be dropped since it is assumed you are using ssh for the encrypted tunnelling. \fB-localhost\fR is still enforced. Use \fB-ssl\fR or \fB-stunnel\fR to force SSL usage even if SSH_CONNECTION is set. .IP To override the above restrictions you can set environment variables before starting x11vnc: .IP Set UNIXPW_DISABLE_SSL=1 to disable requiring either \fB-ssl\fR or \fB-stunnel\fR (as under SSH_CONNECTION.) Evidently you will be using a different method to encrypt the data between the vncviewer and x11vnc: perhaps .IR ssh (1) or an IPSEC VPN. \fB-localhost\fR is still enforced (however, see the next paragraph.) .IP Set UNIXPW_DISABLE_LOCALHOST=1 to disable the \fB-localhost\fR requirement in \fB-unixpw\fR modes. One should never do this (i.e. allow the Unix passwords to be sniffed on the network.) This also disables the localhost requirement for reverse connections (see below.) .IP Note that use of \fB-localhost\fR with .IR ssh (1) (and no \fB-unixpw)\fR is roughly the same as requiring a Unix user login (since a Unix password or the user's public key authentication is used by sshd on the machine where x11vnc runs and only local connections from that machine are accepted). .IP Regarding reverse connections (e.g. \fB-R\fR connect:host and \fB-connect\fR host), when the \fB-localhost\fR constraint is in effect then reverse connections can only be used to connect to the same machine x11vnc is running on (default port 5500). Please use a ssh or stunnel port redirection to the viewer machine to tunnel the reverse connection over an encrypted channel. .IP In \fB-inetd\fR mode the Method 1) will be enforced (not Method 2). With \fB-ssl\fR in effect reverse connections are disabled. If you override this via env. var, be sure to also use encryption from the viewer to inetd. Tip: you can also have your own stunnel spawn x11vnc in \fB-inetd\fR mode (thereby bypassing inetd). See the FAQ for details. .IP The user names in the comma separated [list] may have per-user options after a ":", e.g. "fred:opts" where "opts" is a "+" separated list of "viewonly", "fullaccess", "input=XXXX", or "deny", e.g. "karl,wally:viewonly,boss:input=M". For "input=" it is the K,M,B,C described under \fB-input.\fR .IP If an item in the list is "*" that means those options apply to all users. It ALSO implies all users are allowed to log in after supplying a valid password. Use "deny" to explicitly deny some users if you use "*" to set a global option. If [list] begins with the "!" character then "*" is ignored for checking if the user is allowed, but the option values associated with it do apply as normal. .IP There are also some utilities for checking passwords if [list] starts with the "%" character. See the quick_pw() function for more details. Description: "%-" or "%stdin" means read one line from stdin. "%env" means it is in $UNIXPW env var. A leading "%/" or "%." means read the first line from the filename that follows after the % character. % by itself means prompt for the username and password. Otherwise: %user:pass E.g. \fB-unixpw\fR %fred:swordfish For the other cases user:pass is read from the indicated source. If the password is correct 'Y user' is printed and the program exit code is 0. If the password is incorrect it prints 'N user' and the exit code is 1. If there is some other error the exit code is 2. This feature enables x11vnc to be a general unix user password checking tool; it could be used from scripts or other programs. These % password checks also apply to the \fB-unixpw_nis\fR and \fB-unixpw_cmd\fR options. .IP For the % password check, if the env. var. UNIXPW_CMD is set to a command then it is run as the user (assuming the password is correct.) The output of the command is not printed, the program or script must manage that by some other means. The exit code of x11vnc will depend on the exit code of the command that is run. .IP Use \fB-nounixpw\fR to disable unixpw mode if it was enabled earlier in the cmd line (e.g. \fB-svc\fR mode) .PP \fB-unixpw_nis\fR \fI[list]\fR .IP As \fB-unixpw\fR above, however do not use .IR su (1) but rather use the traditional .IR getpwnam (3) + .IR crypt (3) method to verify passwords. All of the above \fB-unixpw\fR options and constraints apply. .IP This mode requires that the encrypted passwords be readable. Encrypted passwords stored in /etc/shadow will be inaccessible unless x11vnc is run as root. .IP This is called "NIS" mode simply because in most NIS setups user encrypted passwords are accessible (e.g. "ypcat passwd") by an ordinary user and so that user can authenticate ANY user. .IP NIS is not required for this mode to work (only that .IR getpwnam (3) return the encrypted password is required), but it is unlikely it will work (as an ordinary user) for most modern environments unless NIS is available. On the other hand, when x11vnc is run as root it will be able to to access /etc/shadow even if NIS is not available (note running as root is often done when running x11vnc from inetd and xdm/gdm/kdm). .IP Looked at another way, if you do not want to use the .IR su (1) method provided by \fB-unixpw\fR (i.e. su_verify()), you can run x11vnc as root and use \fB-unixpw_nis.\fR Any users with passwords in /etc/shadow can then be authenticated. .IP In \fB-unixpw_nis\fR mode, under no circumstances is x11vnc's user password verifying function based on su called (i.e. the function su_verify() that runs /bin/su in a pseudoterminal to verify passwords.) However, if \fB-unixpw_nis\fR is used in conjunction with the \fB-find\fR and \fB-create\fR \fB-display\fR WAIT:... modes then, if x11vnc is running as root, /bin/su may be called externally to run the find or create commands. .PP \fB-unixpw_cmd\fR \fIcmd\fR .IP As \fB-unixpw\fR above, however do not use .IR su (1) but rather run the externally supplied command \fIcmd\fR. The first line of its stdin will be the username and the second line the received password. If the command exits with status 0 (success) the VNC user will be accepted. It will be rejected for any other return status. .IP Dynamic passwords and non-unix passwords, e.g. LDAP, can be implemented this way by providing your own custom helper program. Note that the remote viewer is given 3 tries to enter the correct password, and so the program may be called in a row that many (or more) times. .IP If a list of allowed users is needed to limit who can log in, use \fB-unixpw\fR [list] in addition to this option. .IP In FINDDISPLAY and FINDCREATEDISPLAY modes the \fIcmd\fR will also be run with the RFB_UNIXPW_CMD_RUN env. var. non-empty and set to the corresponding display find/create command. The first two lines of input are the username and passwd as in the normal case described above. To support FINDDISPLAY and FINDCREATEDISPLAY, \fIcmd\fR should run the requested command as the user (and most likely refusing to run it if the password is not correct.) Here is an example script (note it has a hardwired bogus password "abc"!) .IP #!/bin/sh # Example x11vnc \fB-unixpw_cmd\fR script. # Read the first two lines of stdin (user and passwd) read user read pass .IP debug=0 if [ $debug = 1 ]; then echo "user: $user" 1>&2 echo "pass: $pass" 1>&2 env | egrep \fB-i\fR 'rfb|vnc' 1>&2 fi .IP # Check if the password is valid. # (A real example would use ldap lookup, etc!) if [ "X$pass" != "Xabc" ]; then exit 1 # incorrect password fi .IP if [ "X$RFB_UNIXPW_CMD_RUN" = "X" ]; then exit 0 # correct password else # Run the requested command (finddisplay) if [ $debug = 1 ]; then echo "run: $RFB_UNIXPW_CMD_RUN" 1>&2 fi exec /bin/su - "$user" \fB-c\fR "$RFB_UNIXPW_CMD_RUN" fi .IP In \fB-unixpw_cmd\fR mode, under no circumstances is x11vnc's user password verifying function based on su called (i.e. the function su_verify() that runs /bin/su in a pseudoterminal to verify passwords.) It is up to the supplied unixpw_cmd to do user switching if desired and if it has the permissions to do so. .PP \fB-find\fR .IP Find the user's display using FINDDISPLAY. This is an alias for "\fB-display\fR \fIWAIT:cmd=FINDDISPLAY\fR". .IP Note: if a \fB-display\fR occurs later on the command line it will override the \fB-find\fR setting. .IP For this and the next few options see \fB-display\fR WAIT:... below for all of the details. .PP \fB-finddpy\fR .IP Run the FINDDISPLAY program, print out the found display (if any) and exit. Output is like: DISPLAY=:0.0 DISPLAY=:0.0,XPID=12345 or DISPLAY=:0.0,VT=7. XPID is the process ID of the found X server. VT is the Linux virtual terminal of the X server. .PP \fB-listdpy\fR .IP Have the FINDDISPLAY program list all of your displays (i.e. all the X displays on the local machine that you have access rights to). x11vnc then exits. .PP \fB-findauth\fR \fI[disp]\fR .IP Apply the \fB-find/-finddpy\fR heuristics to try to guess the XAUTHORITY file for DISPLAY 'disp'. If 'disp' is not supplied, then the value in the \fB-display\fR on the cmdline is used; failing that $DISPLAY is used; and failing that ":0" is used. x11vnc then exits. .IP If nothing is printed out, that means no XAUTHORITY was found for 'disp'; i.e. failure. If "XAUTHORITY=" is printed out, that means use the default (i.e. do not set XAUTHORITY). If "XAUTHORITY=/path/to/file" is printed out, then use that file. .IP XDM/GDM/KDM: if you are running x11vnc as root and want to find the XAUTHORITY before anyone has logged into an X session yet, use: x11vnc \fB-env\fR FD_XDM=1 \fB-findauth\fR ... (This will also find the XAUTHORITY if a user is already logged into the X session.) When running as root, FD_XDM=1 will be tried if the initial \fB-findauth\fR fails. .PP \fB-create\fR .IP First try to find the user's display using FINDDISPLAY, if that doesn't succeed create an X session via the FINDCREATEDISPLAY method. This is an alias for "\fB-display\fR \fIWAIT:cmd=FINDCREATEDISPLAY-Xvfb\fR". .IP Note: if a \fB-display\fR occurs later on the command line it will override the \fB-create\fR setting. .IP SSH NOTE: for both \fB-find\fR and \fB-create\fR you can (should!) add the "\fB-localhost\fR" option to force SSH tunnel access. .PP \fB-xdummy\fR .IP As in \fB-create,\fR except Xdummy instead of Xvfb. .PP \fB-xvnc\fR .IP As in \fB-create,\fR except Xvnc instead of Xvfb. .PP \fB-xvnc_redirect\fR .IP As in \fB-create,\fR except Xvnc.redirect instead of Xvfb. .PP \fB-xdummy_xvfb\fR .IP Sets WAIT:cmd=FINDCREATEDISPLAY-Xdummy,Xvfb .PP \fB-create_xsrv\fR \fIstr\fR .IP Sets WAIT:cmd=FINDCREATEDISPLAY-<str> Can be on cmdline after anything that sets WAIT:.. and other things (e.g. \fB-svc,\fR \fB-xdmsvc)\fR to adjust the X server list.

Subsequent re-connections will only require the \fB-unixpw\fR password. See the discussion under \fB-display\fR WAIT:... for more details about XDM, etc configuration. .IP Remember to enable XDMCP in the xdm-config, gdm.conf, or kdmrc configuration file. See \fB-display\fR WAIT: for more info. .PP \fB-sshxdmsvc\fR .IP Display manager Terminal services mode based on SSH. Alias for \fB-display\fR WAIT:cmd=FINDCREATEDISPLAY-Xvfb.xdmcp \fB-localhost.\fR .IP The \fB-localhost\fR option constrains connections to come in via a SSH tunnel (which will require a login). To create a session a user will also have to log into the XDM GDM KDM prompt. Subsequent re-connections will only only require the SSH login. See the discussion under \fB-display\fR WAIT:... for more details about XDM, etc configuration. .IP Remember to enable XDMCP in the xdm-config, gdm.conf, or kdmrc configuration file. See \fB-display\fR WAIT: for more info. .PP \fB-unixpw_system_greeter\fR .IP Present a "Press 'Escape' for System Greeter" option to the connecting VNC client in combined \fB-unixpw\fR and xdmcp FINDCREATEDISPLAY modes (e.g. \fB-xdmsvc).\fR .IP Normally in a \fB-unixpw\fR mode the VNC client must supply a valid username and password to gain access. However, if \fB-unixpw_system_greeter\fR is supplied AND the FINDCREATEDISPLAY command matches 'xdmcp', then the user has the option to press Escape and then get a XDM/GDM/KDM login/greeter panel instead. They will then supply a username and password directly to the greeter. .IP Otherwise, in xdmcp FINDCREATEDISPLAY mode the user must supply his username and password TWICE. First to the initial unixpw login dialog, and second to the subsequent XDM/GDM/KDM greeter. Note that if the user re-connects and supplies his username and password in the unixpw dialog the xdmcp greeter is skipped and he is connected directly to his existing X session. So the \fB-unixpw_system_greeter\fR option avoids the extra password at X session creation time. .IP Example: x11vnc \fB-xdmsvc\fR \fB-unixpw_system_greeter\fR See \fB-unixpw\fR and \fB-display\fR WAIT:... for more info. .IP The special options after a colon at the end of the username (e.g. user:solid) described under \fB-display\fR WAIT: are also applied in this mode if they are typed in before the user hits Escape. The username is ignored but the colon options are not. .IP The default message is 2 lines in a small font, set the env. var. X11VNC_SYSTEM_GREETER1=true for a 1 line message in a larger font. .IP If the user pressed Escape the FINDCREATEDISPLAY command will be run with the env. var. X11VNC_XDM_ONLY=1. .IP Remember to enable XDMCP in the xdm-config, gdm.conf, or kdmrc configuration file. See \fB-display\fR WAIT: for more info. .PP \fB-redirect\fR \fIport\fR .IP As in FINDCREATEDISPLAY-Xvnc.redirect mode except redirect immediately (i.e. without X session finding or creation) to a VNC server listening on port. You can also supply host:port to redirect to a different machine. .IP If 0 <= port < 200 it is taken as a VNC display (5900 is added to get the actual port), if port < 0 then \fB-port\fR is used. .IP Probably the only reason to use the \fB-redirect\fR option is in conjunction with SSL support, e.g. \fB-ssl\fR SAVE. This provides an easy way to add SSL encryption to a VNC server that does not support SSL (e.g. Xvnc or vnc.so) In fact, the protocol does not even need to be VNC, and so "\fB-rfbport\fR \fIport1 \fB-ssl\fR SAVE \fB-redirect\fR host:port2\fR" can act as a replacement for .IR stunnel (1). .IP This mode only allows one redirected connection. The \fB-forever\fR option does not apply. Use \fB-inetd\fR or \fB-loop\fR for persistent service. .PP \fB-display\fR \fIWAIT:...\fR .IP A special usage mode for the normal \fB-display\fR option. Useful with \fB-unixpw,\fR but can be used independently of it. If the display string begins with WAIT: then x11vnc waits until a VNC client connects before opening the X display (or \fB-rawfb\fR device). .IP This could be useful for delaying opening the display for certain usage modes (say if x11vnc is started at boot time and no X server is running or users logged in yet). .IP If the string is, e.g. WAIT:0.0 or WAIT:1, i.e. "WAIT" in front of a normal X display, then that indicated display is used. .IP One can also insert a geometry between colons, e.g. WAIT:1280x1024:... to set the size of the display the VNC client first attaches to since some VNC viewers will not automatically adjust to a new framebuffer size. .IP A more interesting case is like this: .IP WAIT:cmd=/usr/local/bin/find_display .IP in which case the command after "cmd=" is run to dynamically work out the DISPLAY and optionally the XAUTHORITY data. The first line of the command output must be of the form DISPLAY=<xdisplay>. On Linux if the virtual terminal is known append ",VT=n" to this string and the .IR chvt (1) program will also be run. Any remaining output is taken as XAUTHORITY data. It can be either of the form XAUTHORITY=<file> or raw xauthority data for the display. For example; .IP xauth extract - $DISPLAY" .IP NOTE: As specified in the previous paragraph, you can supply your own WAIT:cmd=... program or script, BUT there are two very useful *BUILT-IN* ones: FINDDISPLAY (alias \fB-find\fR above) and FINDCREATEDISPLAY (alias \fB-create\fR above.) Most people use these instead of creating their own script. Read the following (especially the BUILT-IN modes sections) to see how to configure these two useful builtin \fB-display\fR WAIT: modes. .IP In the case of \fB-unixpw\fR (and \fB-unixpw_nis\fR only if x11vnc is running as root), then the cmd= command is run as the user who just authenticated via the login and password prompt. .IP In the case of \fB-unixpw_cmd,\fR the commands will also be run as the logged-in user, as long as the user-supplied helper program supports RFB_UNIXPW_CMD_RUN (see the \fB-unixpw_cmd\fR option.) .IP Also in the case of \fB-unixpw,\fR the user logging in can place a colon at the end of her username and supply a few options: scale=, scale_cursor= (or sc=), solid (or so), id=, clear_mods (or cm), clear_keys (or ck), clear_all (or ca), repeat, speeds= (or sp=), readtimeout= (or rd=), viewonly (or vo), nodisplay= (or nd=), rotate= (or ro=), or noncache (or nc), all separated by commas if there is more than one. After the user logs in successfully, these options will be applied to the VNC screen. For example, .IP login: fred:scale=3/4,sc=1,repeat Password: ... .IP login: runge:sp=modem,rd=120,solid .IP for convenience m/n implies scale= e.g. fred:3/4 If you type and enter your password incorrectly, to retrieve your long "login:" line press the Up arrow once (before typing anything else). .IP Most of these colon options only apply to the builtin FINDDISPLAY and FINDCREATEDISPLAY modes, but note that they are passed to the extrenal command in the environment as well and so could be used. .IP In the login panel, press F1 to get a list of the available options that you can add after the username. .IP Another option is "geom=WxH" or "geom=WxHxD" (or ge=). This only has an effect in FINDCREATEDISPLAY mode when a virtual X server such as Xvfb is going to be created. It sets the width and height of the new display, and optionally the color depth as well. .IP You can also supply "gnome", "kde", "twm", "fvwm", "mwm", "dtwm", "wmaker", "xfce", "lxde", "enlightenment", "Xsession", or "failsafe" (same as "xterm") to have the created display use that mode for the user session. .IP Specify "tag=..." to set the unique FD_TAG desktop session tag described below. Note: this option will be ignored if the FD_TAG env. var. is already set or if the viewer-side supplied value is not completely composed of alphanumeric or '_' or '-' characters. .IP User preferences file: Instead of having the user type in geom=WxH,... etc. every time he logs in to find or create his X session, if you set FD_USERPREFS to a string that does not contain the "/" character, then the user's home directory is prepended to that string and if the file exists its first line is read and appended to any options he supplied at the login: prompt. For example \fB-env\fR FD_USERPREFS=.x11vnc_create and the user put "geom=1600x1200" in his ~/.x11vnc_create file. .IP To disable the option setting set the environment variable X11VNC_NO_UNIXPW_OPTS=1 before starting x11vnc. To set any other options, the user can use the gui (x11vnc \fB-gui\fR connect) or the remote control method (x11vnc \fB-R\fR opt:val) during his VNC session. .IP So we see the combination of \fB-display\fR WAIT:cmd=... and \fB-unixpw\fR allows automatic pairing of an unix authenticated VNC user with his desktop. This could be very useful on SunRays and also any system where multiple users share a given machine. The user does not need to remember special ports or passwords set up for his desktop and VNC. .IP A nice way to use WAIT:cmd=... is out of .IR inetd (8) (it automatically forks a new x11vnc for each user). You can have the x11vnc inetd spawned process run as, say, root or nobody. When run as root (for either inetd or display manager), you can also supply the option "\fB-users\fR \fIunixpw=\fR" to have the x11vnc process switch to the user as well. Note: there will be a 2nd SSL helper process that will not switch, but it is only encoding and decoding the encrypted stream at that point. .IP BUILT-IN modes: .IP \fB--\fR Automatic Finding of User X Sessions \fB--\fR .IP As a special case, WAIT:cmd=FINDDISPLAY will run a script that works on most Unixes to determine a user's DISPLAY variable and xauthority data (see .IR who (1) ). .IP NOTE: The option "\fB-find\fR" is an alias for this mode. .IP To have this default script printed to stdout (e.g. for customization) run with WAIT:cmd=FINDDISPLAY-print To have the script run to print what display it would find use "\fB-finddpy\fR" or WAIT:cmd=FINDDISPLAY-run .IP The standard script runs .IR xdpyinfo (1) run on potential displays. If your X server(s) have a login greeter that exclusively grabs the Xserver, then xdpyinfo blocks forever and this mode will not work. See www.karlrunge.com/x11vnc/faq.html#faq-display-manager for how to disable this for dtgreet on Solaris and possibly for other greeters. .IP In \fB-find/cmd=FINDDISPLAY\fR mode, if you set FD_XDM=1, e.g. 'x11vnc \fB-env\fR FD_XDM=1 \fB-find\fR ...' and x11vnc is running as root (e.g. inetd) then it will try to find the XAUTHORITY file of a running XDM/GDM/KDM login greeter (i.e. no user has logged into an X session yet.) .IP As another special case, WAIT:cmd=HTTPONCE will allow x11vnc to service one http request and then exit. This is usually done in \fB-inetd\fR mode to run on, say, port 5800 and allow the Java vncviewer to be downloaded by client web browsers. For example: .IP 5815 stream tcp nowait root /usr/sbin/tcpd /.../x11vnc \\ \fB-inetd\fR \fB-q\fR \fB-http_ssl\fR \fB-prog\fR /.../x11vnc \\ \fB-display\fR WAIT:cmd=HTTPONCE .IP Where /.../x11vnc is the full path to x11vnc. It is used in the Apache SSL-portal example (see FAQ). .IP In this mode you can set X11VNC_SKIP_DISPLAY to a comma separated list of displays (e.g. ":0,:1") to ignore in the finding process. The ":" is optional. Ranges n-m e.g. 0-20 can also be supplied. This string can also be set by the connecting user via "nd=" using "+" instead of "," If "nd=all" or you set X11VNC_SKIP_DISPLAY=all then all display finding fails as if you set X11VNC_FINDDISPLAY_ALWAYS_FAILS=1 (below.) .IP On some systems .IR lsof (1) can be very slow. Set the env. var. FIND_DISPLAY_NO_LSOF=1 to skip using lsof to try to find the Linux VT the X server is running on. set FIND_DISPLAY_NO_VT_FIND=1 to avoid looking at all. .IP \fB--\fR Automatic Creation of User X Sessions \fB--\fR .IP An interesting option is WAIT:cmd=FINDCREATEDISPLAY that is like FINDDISPLAY in that is uses the same method to find an existing display. However, if it does not find one it will try to *start* up an X server session for the user. This is the only time x11vnc tries to actually start up an X server. .IP NOTE: The option "\fB-create\fR" is an alias for this mode. .IP It will start looking for an open display number at :20 Override via X11VNC_CREATE_STARTING_DISPLAY_NUMBER=n By default 80 X displays are allowed (i.e. going to :99) Override via X11VNC_CREATE_MAX_DISPLAYS=n .IP For its heuristics, the create display script sets LC_ALL=C so that command output is uniform. By default it will try to restore LC_ALL right before starting the user session. However, if you don't mind it keeping LC_ALL=C set the env. var.: X11VNC_CREATE_LC_ALL_C_OK=1 .IP By default FINDCREATEDISPLAY will try Xvfb and then Xdummy: .IP The Xdummy wrapper is part of the x11vnc source code (x11vnc/misc/Xdummy) It should be available in PATH and have run "Xdummy \fB-install"\fR once to create the shared library. Xdummy only works on Linux. As of 12/2009 it no longer needs to be run as root, and the default is to not run as root. In some circumstances permissions may require running it as root, in these cases specify FD_XDUMMY_RUN_AS_ROOT=1, this is the same as supplying \fB-root\fR to the Xdummy cmdline. .IP Xvfb is available on most platforms and does not require root. .IP An advantage of Xdummy over Xvfb is that Xdummy supports RANDR dynamic screen resizing. .IP When x11vnc exits (i.e. user disconnects) the X server session stays running in the background. The FINDDISPLAY will find it directly next time. The user must exit the X session in the usual way for it to terminate (or kill the X server process if all else fails). .IP To troubleshoot the FINDCREATEDISPLAY mechanism, set the following env. var. to an output log file, e.g \fB-env\fR CREATE_DISPLAY_OUTPUT=/tmp/mydebug.txt .IP So this is a somewhat odd mode for x11vnc in that it will start up and poll virtual X servers! This can be used from, say, .IR inetd (8) to provide a means of definitely getting a desktop (either real or virtual) on the machine. E.g. a desktop service: .IP 5900 stream tcp nowait root /usr/sbin/tcpd /.../x11vnc \fB-inetd\fR \fB-q\fR \fB-http\fR \fB-ssl\fR SAVE \fB-unixpw\fR \fB-users\fR unixpw=\\ \fB-passwd\fR secret \fB-prog\fR /.../x11vnc \\ \fB-display\fR WAIT:cmd=FINDCREATEDISPLAY .IP Where /.../x11vnc is the full path to x11vnc. .IP See the \fB-svc/-service\fR option alias above. .IP If for some reason you do not want x11vnc to ever try to find an existing display set the env. var X11VNC_FINDDISPLAY_ALWAYS_FAILS=1 (also \fB-env\fR ...) This is the same as setting X11VNC_SKIP_DISPLAY=all or supplying "nd=all" after "username:" .IP Use WAIT:cmd=FINDCREATEDISPLAY-print to print out the script that is used for this. .IP You can specify the preferred X server order via e.g., WAIT:cmd=FINDCREATEDISPLAY-Xdummy,Xvfb,X and/or leave out ones you do not want. The the case "X" means try to start up a real, hardware X server using .IR xinit (1) or .IR startx (1). If there is already an X server running the X case may only work on Linux (see .IR startx (1) ). .IP "Xvnc" will start up a VNC X server (real- or tight-vnc, e.g. use if Xvfb is not available). "Xsrv" will start up the server program in the variable "FD_XSRV" if it is non-empty. You can make this be a wrapper script if you like (it must handle :N, \fB-geometry,\fR and \fB-depth\fR and other X server options). .IP You can set the environment variable FD_GEOM (or X11VNC_CREATE_GEOM) to WxH or WxHxD to set the width and height and optionally the color depth of the created display. You can also set FD_SESS to be the session (short name of the windowmanager: kde, gnome, twm, failsafe, etc.). FD_OPTS contains extra options to pass to the X server. You can also set FD_PROG to be the full path to the session/windowmanager program. .IP More FD tricks: FD_CUPS=port or FD_CUPS=host:port will set the cups printing environment. Similarly for FD_ESD=port or FD_ESD=host:port for esddsp sound redirection. Set FD_EXTRA to a command to be run a few seconds after the X server starts up. Set FD_TAG to be a unique name for the session, it is set as an X property, that makes FINDDISPLAY only find sessions with that tag value. .IP Set FD_XDMCP_IF to the network interface that the display manager is running on; default is 'localhost' but you may need to set it to '::1' on some IPv6 only systems or misconfigured display managers. .IP If you want the FINDCREATEDISPLAY session to contact an XDMCP login manager (xdm/gdm/kdm) on the same machine, then use "Xvfb.xdmcp" instead of "Xvfb", etc. The user will have to supply his username and password one more time (but he gets to select his desktop type so that can be useful). For this to work, you will need to enable localhost XDMCP (udp port 177) for the display manager. This seems to be: .IP for gdm in gdm.conf: Enable=true in section [xdmcp] for kdm in kdmrc: Enable=true in section [Xdmcp] for xdm in xdm-config: DisplayManager.requestPort: 177 .IP See the shorthand options above "\fB-svc\fR", "\fB-xdmsvc\fR" and "\fB-sshxdmsvc\fR" that specify the above options for some useful cases. .IP If you set the env. var WAITBG=1 x11vnc will go into the background once listening in wait mode. .IP Another special mode is FINDCREATEDISPLAY-Xvnc.redirect, (or FINDDISPLAY-Xvnc.redirect). In this case it will start up Xvnc as above if needed, but instead of polling it in its normal way, it simply does a socket redirection of the connected VNC viewer to the Xvnc. .IP So in Xvnc.redirect x11vnc does no VNC but merely transfers the data back and forth. This should be faster then x11vnc's polling method, but not as fast as connecting directly to the Xvnc with the VNC Viewer. The idea here is to take advantage of x11vnc's display finding/creating scheme, SSL, and perhaps a few others. Most of x11vnc's options do not apply in this mode. .IP Xvnc.redirect should also work for the vnc.so X server module for the h/w display however it will work only for finding the display and the user must already be logged into the X console. .PP \fB-vencrypt\fR \fImode\fR .IP The VeNCrypt extension to the VNC protocol allows encrypted SSL/TLS connections. If the \fB-ssl\fR mode is enabled, then VeNCrypt is enabled as well BY DEFAULT (they both use a SSL/TLS tunnel, only the protocol handshake is a little different.) .IP To control when and how VeNCrypt is used, specify the mode string. If mode is "never", then VeNCrypt is not used. If mode is "support" (the default) then VeNCrypt is supported. If mode is "only", then the similar and older ANONTLS protocol is not simultaneously supported. x11vnc's normal SSL mode (vncs://) will be supported under \fB-ssl\fR unless you set mode to "force". .IP If mode is prefixed with "nodh:", then Diffie Hellman anonymous key exchange is disabled. If mode is prefixed with "nox509:", then X509 key exchange is disabled. .IP To disable all Anonymous Diffie-Hellman access (susceptible to Man-In-The-Middle attack) you will need to supply "\fB-vencrypt\fR \fInodh:support \fB-anontls\fR never\fR" or "\fB-vencrypt\fR \fInodh:only\fR" .IP If mode is prefixed with "newdh:", then new Diffie Hellman parameters are generated for each connection (this can be time consuming: 1-60 secs; see \fB-dhparams\fR below for a faster way) rather than using the fixed values in the program. Using fixed, publicly known values is not known to be a security problem. This setting applies to ANONTLS as well. .IP Long example: \fB-vencrypt\fR newdh:nox509:support .IP Also, if mode is prefixed with "plain:", then if \fB-unixpw\fR mode is active the VeNCrypt "*Plain" username+passwd method is enabled for Unix logins. Otherwise in \fB-unixpw\fR mode the normal login panel is provided. .IP You *MUST* supply the \fB-ssl\fR option for VeNCrypt to be active. The \fB-vencrypt\fR option only fine-tunes its operation. .PP \fB-anontls\fR \fImode\fR .IP The ANONTLS extension to the VNC protocol allows encrypted SSL/TLS connections. If the \fB-ssl\fR mode is enabled, then ANONTLS is enabled as well BY DEFAULT (they both use a SSL/TLS tunnel, only the protocol handshake is a little different.) .IP ANONTLS is an older SSL/TLS mode introduced by vino. .IP It is referred to as 'TLS' for its registered VNC security-type name, but we use the more descriptive \(aqANONTLS\(aq here because it provides only Anonymous Diffie-Hellman encrypted connections, and hence no possibility for certificate authentication. .IP To control when and how ANONTLS is used, specify the mode string. If mode is "never", then ANONTLS is not used. If mode is "support" (the default) then ANONTLS is supported. If mode is "only", then the similar VeNCrypt protocol is not simultaneously supported. x11vnc's normal SSL mode (vncs://) will be supported under \fB-ssl\fR unless you set mode to "force". .IP If mode is prefixed with "newdh:", then new Diffie Hellman parameters are generated for each connection (this can be time consuming: 1-60 secs; see \fB-dhparams\fR below for a faster way) rather than using the fixed values in the program. Using fixed, publicly known values is not known to be a security problem. This setting applies to VeNCrypt as well. See the description of "plain:" under \fB-vencrypt.\fR .IP Long example: \fB-anontls\fR newdh:plain:support .IP You *MUST* supply the \fB-ssl\fR option for ANONTLS to be active. The \fB-anontls\fR option only fine-tunes its operation. .PP \fB-sslonly\fR .IP Same as: "\fB-vencrypt\fR \fInever \fB-anontls\fR never\fR" i.e. it disables the VeNCrypt and ANONTLS encryption methods and only allows standard SSL tunneling. You must also supply the \fB-ssl\fR ... option (see below.) .PP \fB-dhparams\fR \fIfile\fR .IP For some operations a set of Diffie Hellman parameters (prime and generator) is needed. If so, use the parameters in \fIfile\fR. In particular, the VeNCrypt and ANONTLS anonymous DH mode need them. By default a fixed set is used. If you do not want to do that you can specify "newdh:" to the \fB-vencrypt\fR and \fB-anontls\fR options to generate a new set each session. If that is too slow for you, use \fB-dhparams\fR file to a set you created manually via "openssl dhparam \fB-out\fR file 1024" .PP \fB-nossl\fR .IP Disable the \fB-ssl\fR option (see below). Since \fB-ssl\fR is off by default \fB-nossl\fR would only be used on the commandline to unset any *earlier* \fB-ssl\fR option (or \fB-svc...)\fR .PP \fB-ssl\fR \fI[pem]\fR .IP Use the openssl library (www.openssl.org) to provide a built-in encrypted SSL/TLS tunnel between VNC viewers and x11vnc. This requires libssl support to be compiled into x11vnc at build time. If x11vnc is not built with libssl support it will exit immediately when \fB-ssl\fR is prescribed. See the \fB-stunnel\fR option below for an alternative. .IP The VNC Viewer-side needs to support SSL/TLS as well. See this URL and also the discussion below for ideas on how to enable SSL support for the viewer: http://www.karlrunge.com/x11vnc/faq.html#faq-ssl-tun nel-viewers . x11vnc provides an SSL enabled Java viewer applet in the classes/ssl directory (-http or \fB-httpdir\fR options.) The SSVNC viewer package supports SSL tunnels too. .IP If the VNC Viewer supports VeNCrypt or ANONTLS (vino's encryption mode) they are also supported by the \fB-ssl\fR mode (see the \fB-vencrypt\fR and \fB-anontls\fR options for more info; use \fB-sslonly\fR to disable both of them.) .IP Use "\fB-ssl\fR \fI/path/to/mycert.pem\fR" to specify an SSL certificate file in PEM format to use to identify and provide a key for this server. See .IR openssl (1) for more info about PEMs and the \fB-sslGenCert\fR and "\fB-ssl\fR \fISAVE\fR" options below for how to create them. .IP The connecting VNC viewer SSL tunnel can (at its option) authenticate this server if it has the public key part of the certificate (or a common certificate authority, CA, is a more sophisticated way to verify this server's cert, see \fB-sslGenCA\fR below). This authentication is done to prevent Man-In-The-Middle attacks. Otherwise, if the VNC viewer simply accepts this server's key WITHOUT verification, the traffic is protected from passive sniffing on the network, but *NOT* from Man-In-The-Middle attacks. There are hacker tools like dsniff/webmitm and cain that implement SSL Man-In-The-Middle attacks. .IP If [pem] is empty or the string "SAVE" then the .IR openssl (1) command must be available to generate the certificate the first time. A self-signed certificate is generated (see \fB-sslGenCA\fR and \fB-sslGenCert\fR for use of a Certificate Authority.) It will be saved to the file ~/.vnc/certs/server.pem. On subsequent calls if that file already exists it will be used directly. .IP Use "SAVE_NOPROMPT" to avoid being prompted to protect the generated key with a passphrase. However in \fB-inetd\fR and \fB-bg\fR modes there will be no prompting for a passphrase in either case. .IP If [pem] is "SAVE_PROMPT" the server.pem certificate will be created based on your answers to its prompts for all info such as OrganizationalName, CommonName, etc. .IP Use "SAVE-<string>" and "SAVE_PROMPT-<string>" to refer to the file ~/.vnc/certs/server-<string>.pem instead (it will be generated if it does not already exist). E.g. "SAVE-charlie" will store to the file ~/.vnc/certs/server-charlie.pem .IP Examples: x11vnc \fB-ssl\fR SAVE \fB-display\fR :0 ... x11vnc \fB-ssl\fR SAVE-someother \fB-display\fR :0 ... .IP If [pem] is "TMP" and the .IR openssl (1) utility command exists in PATH, then a temporary, self-signed certificate will be generated for this session. If .IR openssl (1) cannot be used to generate a temporary certificate x11vnc exits immediately. The temporary cert will be discarded when x11vnc exits. .IP If successful in using .IR openssl (1) to generate a temporary certificate in "SAVE" or "TMP" creation modes, the public part of it will be displayed to stderr (e.g. one could copy it to the client-side to provide authentication of the server to VNC viewers.) .IP NOTE: In "TMP" mode, unless you safely copy the public part of the temporary Cert to the viewer for authenticate *every time* (unlikely...), then only passive sniffing attacks are prevented and you are still open to Man-In-The-Middle attacks. This is why the default "SAVE" mode is preferred (and more sophisticated CA mode too). Only with saved keys AND the VNC viewer authenticating them (via the public certificate), are Man-In-The-Middle attacks prevented. .IP If [pem] is "ANON" then the Diffie-Hellman anonymous key exchange method is used. In this mode there are *no* SSL certificates and so it is not possible to authenticate either the VNC server or VNC client. Thus only passive network sniffing attacks are avoided: the "ANON" method is susceptible to Man-In-The-Middle attacks. "ANON" is not recommended; instead use a SSL PEM you created or the default "SAVE" method. .IP See \fB-ssldir\fR below to use a directory besides the default ~/.vnc/certs .IP If your x11vnc binary was not compiled with OpenSSL library support, use of the \fB-ssl\fR option will induce an immediate failure and exit. For such binaries, consider using the \fB-stunnel\fR option for SSL encrypted connections. .IP Misc Info: In temporary cert creation mode "TMP", set the env. var. X11VNC_SHOW_TMP_PEM=1 to have x11vnc print out the entire certificate, including the PRIVATE KEY part, to stderr. There are better ways to get/save this info. See "SAVE" above and "\fB-sslGenCert\fR" below. .PP \fB-ssltimeout\fR \fIn\fR .IP Set SSL read timeout to n seconds. In some situations (i.e. an iconified viewer in Windows) the viewer stops talking and the connection is dropped after the default timeout (25s for about the first minute, 43200s later). Set to zero to poll forever. Set to a negative value to use the builtin setting. .IP Note that this value does NOT apply to the *initial* ssl init connection. The default timeout for that is 20sec. Use \fB-env\fR SSL_INIT_TIMEOUT=n to modify it. .PP \fB-sslnofail\fR .IP Exit at the first SSL connection failure. Useful when scripting SSL connections (e.g. x11vnc is started via ssh) and you do not want x11vnc waiting around for more connections, tying up ports, etc. .PP \fB-ssldir\fR \fIdir\fR .IP Use \fIdir\fR as an alternate ssl certificate and key management toplevel directory. The default is ~/.vnc/certs .IP This directory is used to store server and other certificates and keys and also other materials. E.g. in the simplest case, "\fB-ssl\fR \fISAVE\fR" will store the x11vnc server cert in dir/server.pem .IP Use of alternate directories via \fB-ssldir\fR allows you to manage multiple VNC Certificate Authority (CA) keys. Another use is if ~/.vnc/cert is on an NFS share you might want your certificates and keys to be on a local filesystem to prevent network snooping (for example \fB-ssldir\fR /var/lib/x11vnc-certs). .IP \fB-ssldir\fR affects nearly all of the other \fB-ssl*\fR options, e.g. \fB-ssl\fR SAVE, \fB-sslGenCert,\fR etc.. .PP \fB-sslverify\fR \fIpath\fR .IP For either of the \fB-ssl\fR or \fB-stunnel\fR modes, use \fIpath\fR to provide certificates to authenticate incoming VNC *Client* connections (normally only the server is authenticated in SSL.) This can be used as a method to replace standard password authentication of clients. .IP If \fIpath\fR is a directory it contains the client (or CA) certificates in separate files. If path is a file, it contains one or more certificates. See special tokens below. These correspond to the "CApath = dir" and "CAfile = file" stunnel options. See the .IR stunnel (8) manpage for details. .IP Examples: x11vnc \fB-ssl\fR \fB-sslverify\fR ~/my.crt x11vnc \fB-ssl\fR \fB-sslverify\fR ~/my_pem_dir/ .IP Note that if path is a directory, it must contain the certs in separate files named like <HASH>.0, where the value of <HASH> is found by running the command "openssl x509 \fB-hash\fR \fB-noout\fR \fB-in\fR file.crt". Evidently one uses <HASH>.1 if there is a collision... .IP The the key-management utility "\fB-sslCertInfo\fR \fIHASHON\fR" and "\fB-sslCertInfo\fR \fIHASHOFF\fR" will create/delete these hashes for you automatically (via symlink) in the HASH subdirs it manages. Then you can point \fB-sslverify\fR to the HASH subdir. .IP Special tokens: in \fB-ssl\fR mode, if \fIpath\fR is not a file or a directory, it is taken as a comma separated list of tokens that are interpreted as follows: .IP If a token is "CA" that means load the CA/cacert.pem file from the ssl directory. If a token is "clients" then all the files clients/*.crt in the ssl directory are loaded. Otherwise the file clients/token.crt is attempted to be loaded. As a kludge, use a token like ../server-foo to load a server cert if you find that necessary. .IP Use \fB-ssldir\fR to use a directory different from the ~/.vnc/certs default. .IP Note that if the "CA" cert is loaded you do not need to load any of the certs that have been signed by it. You will need to load any additional self-signed certs however. .IP Examples: x11vnc \fB-ssl\fR \fB-sslverify\fR CA x11vnc \fB-ssl\fR \fB-sslverify\fR self:fred,self:jim x11vnc \fB-ssl\fR \fB-sslverify\fR CA,clients .IP Usually "\fB-sslverify\fR \fICA\fR" is the most effective. See the \fB-sslGenCA\fR and \fB-sslGenCert\fR options below for how to set up and manage the CA framework. .IP NOTE: the following utilities, \fB-sslGenCA,\fR \fB-sslGenCert,\fR \fB-sslEncKey,\fR \fB-sslCertInfo,\fR and \fB-sslCRL\fR are provided for completeness, but for casual usage they are overkill. .IP They provide VNC Certificate Authority (CA) key creation and server / client key generation and signing. So they provide a basic Public Key management framework for VNC-ing with x11vnc. (note that they require .IR openssl (1) be installed on the system) .IP However, the simplest usage mode, "\fB-ssl\fR \fITMP\fR" (where x11vnc automatically generates its own, self-signed, temporary key and the VNC viewers always accept it, e.g. accepting via a dialog box) is probably safe enough for most scenarios. CA management is not needed. .IP To protect against Man-In-The-Middle attacks the "TMP" mode can be improved by using "\fB-ssl\fR \fISAVE\fR" (same as "\fB-ssl\fR", i.e. the default) to have x11vnc create a longer term self-signed certificate, and then (safely) copy the corresponding public key cert to the desired client machines (care must be taken the private key part is not stolen; you will be prompted for a passphrase). .IP So keep in mind no CA key creation or management (-sslGenCA and \fB-sslGenCert)\fR is needed for either of the above two common usage modes. .IP One might want to use \fB-sslGenCA\fR and \fB-sslGenCert\fR if you had a large number of VNC client and server workstations. That way the administrator could generate a single CA key with \fB-sslGenCA\fR and distribute its certificate part to all of the workstations. .IP Next, he could create signed VNC server keys (-sslGenCert server ...) for each workstation or user that then x11vnc would use to authenticate itself to any VNC client that has the CA cert. .IP Optionally, the admin could also make it so the VNC clients themselves are authenticated to x11vnc (-sslGenCert client ...) For this \fB-sslverify\fR would be pointed to the CA cert (and/or self-signed certs). .IP x11vnc will be able to use all of these cert and key files. On the VNC client side, they will need to be "imported" somehow. Web browsers have "Manage Certificates" actions as does the Java applet plugin Control Panel. stunnel can also use these files (see the ss_vncviewer example script in the FAQ and SSVNC.) .PP \fB-sslCRL\fR \fIpath\fR .IP Set the Certificate Revocation Lists (CRL) to \fIpath\fR. This setting applies for both \fB-ssl\fR and \fB-stunnel\fR modes. .IP If path is a file, the file contains one or more CRLs in PEM format. If path is a directory, it contains hash named files of CRLs in the usual OpenSSL manner. See the OpenSSL and .IR stunnel (8) documentation for more info. .IP This option only applies if \fB-sslverify\fR has been supplied: it checks for revocation along the certificate chain used to verify the VNC client. The \fB-sslCRL\fR setting will be ignored when \fB-sslverify\fR is not specified. .IP Note that if a CRL's expiration date has passed, all SSL connections will fail regardless of if they are related to the subject of the CRL or not. .IP Only rarely will one's x11vnc \fB-ssl\fR infrastructure be so large that this option would be useful (since normally maintaining the contents of the \fB-sslverify\fR file or directory should be enough.) However, when using x11vnc with a Certificate Authority (see \fB-sslGenCA)\fR to authenticate Clients via SSL/TLS, the \fB-sslCRL\fR option can be useful to revoke users' certs whose private SSL keys were lost or stolen (e.g. laptop.) This way a new CA cert+key does not need to be created and new signed client keys generated and distributed to all users. .IP To create a CRL file with revoked certificates the commands 'openssl ca \fB-revoke\fR ...' and 'openssl ca \fB-gencrl\fR ...' are useful. (Run them in ~/.vnc/certs) .PP \fB-sslGenCA\fR \fI[dir]\fR .IP Generate your own Certificate Authority private key, certificate, and other files in directory [dir]. x11vnc then exits. .IP If [dir] is not supplied, a \fB-ssldir\fR setting is used, or otherwise ~/.vnc/certs is used. .IP This command also creates directories where server and client certs and keys will be stored. The .IR openssl (1) program must be installed on the system and available in PATH. .IP After the CA files and directories are created the x11vnc command exits; the VNC server is not run. .IP You will be prompted for information to put into the CA certificate. The info does not have to be accurate just as long as clients accept the cert for VNC connections. You will also need to supply a passphrase of at least 4 characters for the CA private key. .IP Once you have generated the CA you can distribute its certificate part, [dir]/CA/cacert.pem, to other workstations where VNC viewers will be run. One will need to "import" this certificate in the applications, e.g. Web browser, Java applet plugin, stunnel, etc. Next, you can create and sign keys using the CA with the \fB-sslGenCert\fR option below. .IP Examples: x11vnc \fB-sslGenCA\fR x11vnc \fB-sslGenCA\fR ~/myCAdir x11vnc \fB-ssldir\fR ~/myCAdir \fB-sslGenCA\fR .IP (the last two lines are equivalent) .PP \fB-sslGenCert\fR \fItype\fR \fIname\fR .IP Generate a VNC server or client certificate and private key pair signed by the CA created previously with \fB-sslGenCA.\fR The .IR openssl (1) program must be installed on the system and available in PATH. .IP After the Certificate is generated x11vnc exits; the VNC server is not run. .IP The type of key to be generated is the string \fItype\fR. It is either "server" (i.e. for use by x11vnc) or "client" (for a VNC viewer). Note that typically only "server" is used: the VNC clients authenticate themselves by a non-public-key method (e.g. VNC or unix password). \fItype\fR is required. .IP An arbitrary default name you want to associate with the key is supplied by the \fIname\fR string. You can change it at the various prompts when creating the key. \fIname\fR is optional. .IP If name is left blank for clients keys then "nobody" is used. If left blank for server keys, then the primary server key: "server.pem" is created (this is the saved one referenced by "\fB-ssl\fR \fISAVE\fR" when the server is started) .IP If \fIname\fR begins with the string "self:" then a self-signed certificate is created instead of one signed by your CA key. .IP If \fIname\fR begins with the string "req:" then only a key (.key) and a certificate signing *request* (.req) are generated. You can then send the .req file to an external CA (even a professional one, e.g. Thawte) and then combine the .key and the received cert into the .pem file with the same basename. .IP The distinction between "server" and "client" is simply the choice of output filenames and sub-directory. This makes it so the \fB-ssl\fR SAVE-name option can easily pick up the x11vnc PEM file this option generates. And similarly makes it easy for the \fB-sslverify\fR option to pick up your client certs. .IP There is nothing special about the filename or directory location of either the "server" and "client" certs. You can rename the files or move them to wherever you like. .IP Precede this option with \fB-ssldir\fR [dir] to use a directory other than the default ~/.vnc/certs You will need to run \fB-sslGenCA\fR on that directory first before doing any \fB-sslGenCert\fR key creation. .IP Note you cannot recreate a cert with exactly the same distiguished name (DN) as an existing one. To do so, you will need to edit the [dir]/CA/index.txt file to delete the line. .IP Similar to \fB-sslGenCA,\fR you will be prompted to fill in some information that will be recorded in the certificate when it is created. .IP Tip: if you know the fully-qualified hostname other people will be connecting to, you can use that as the CommonName "CN" to avoid some applications (e.g. web browsers and java plugin) complaining that it does not match the hostname. .IP You will also need to supply the CA private key passphrase to unlock the private key created from \fB-sslGenCA.\fR This private key is used to sign the server or client certificate. .IP The "server" certs can be used by x11vnc directly by pointing to them via the \fB-ssl\fR [pem] option. The default file will be ~/.vnc/certs/server.pem. This one would be used by simply typing \fB-ssl\fR SAVE. The pem file contains both the certificate and the private key. server.crt file contains the cert only. .IP The "client" cert + private key file will need to be copied and imported into the VNC viewer side applications (Web browser, Java plugin, stunnel, etc.) Once that is done you can delete the "client" private key file on this machine since it is only needed on the VNC viewer side. The, e.g. ~/.vnc/certs/clients/<name>.pem contains both the cert and private key. The <name>.crt contains the certificate only. .IP NOTE: It is very important to know one should generate new keys with a passphrase. Otherwise if an untrusted user steals the key file he could use it to masquerade as the x11vnc server (or VNC viewer client). You will be prompted whether to encrypt the key with a passphrase or not. It is recommended that you do. One inconvenience to a passphrase is that it must be typed in EVERY time x11vnc or the client app is started up. .IP Examples: .IP x11vnc \fB-sslGenCert\fR server x11vnc \fB-ssl\fR SAVE \fB-display\fR :0 ... .IP and then on viewer using ss_vncviewer stunnel wrapper (see the FAQ): ss_vncviewer \fB-verify\fR ./cacert.crt hostname:0 .IP (this assumes the cacert.crt cert from \fB-sslGenCA\fR was safely copied to the VNC viewer machine where ss_vncviewer is run) .IP Example using a name: .IP x11vnc \fB-sslGenCert\fR server charlie x11vnc \fB-ssl\fR SAVE-charlie \fB-display\fR :0 ... .IP Example for a client certificate (rarely used): .IP x11vnc \fB-sslGenCert\fR client roger scp ~/.vnc/certs/clients/roger.pem somehost:. rm ~/.vnc/certs/clients/roger.pem .IP x11vnc is then started with the option \fB-sslverify\fR ~/.vnc/certs/clients/roger.crt (or simply \fB-sslverify\fR roger), and on the viewer user on somehost could do for example: .IP ss_vncviewer \fB-mycert\fR ./roger.pem hostname:0 .IP If you set the env. var REQ_ARGS='...' it will be passed to openssl .IR req (1). A common use would be REQ_ARGS='-days 1095' to bump up the expiration date (3 years in this case). .PP \fB-sslEncKey\fR \fIpem\fR .IP Utility to encrypt an existing PEM file with a passphrase you supply when prompted. For that key to be used (e.g. by x11vnc) the passphrase must be supplied each time. .IP The "SAVE" notation described under \fB-ssl\fR applies as well. (precede this option with \fB-ssldir\fR [dir] to refer a directory besides the default ~/.vnc/certs) .IP The .IR openssl (1) program must be installed on the system and available in PATH. After the Key file is encrypted the x11vnc command exits; the VNC server is not run. .IP Examples: x11vnc \fB-sslEncKey\fR /path/to/foo.pem x11vnc \fB-sslEncKey\fR SAVE x11vnc \fB-sslEncKey\fR SAVE-charlie .PP \fB-sslCertInfo\fR \fIpem\fR .IP Prints out information about an existing PEM file. In addition the public certificate is also printed. The .IR openssl (1) program must be in PATH. Basically the command "openssl x509 \fB-text"\fR is run on the pem. .IP After the info is printed the x11vnc command exits; the VNC server is not run. .IP The "SAVE" notation described under \fB-ssl\fR applies as well. .IP Using "LIST" will give a list of all certs being managed (in the ~/.vnc/certs dir, use \fB-ssldir\fR to refer to another dir). "ALL" will print out the info for every managed key (this can be very long). Giving a client or server cert shortname will also try a lookup (e.g. \fB-sslCertInfo\fR charlie). Use "LISTL" or "LL" for a long (ls \fB-l\fR style) listing. .IP Using "HASHON" will create subdirs [dir]/HASH and [dir]/HASH with OpenSSL hash filenames (e.g. 0d5fbbf1.0) symlinks pointing up to the corresponding *.crt file. ([dir] is ~/.vnc/certs or one given by \fB-ssldir.)\fR This is a useful way for other OpenSSL applications (e.g. stunnel) to access all of the certs without having to concatenate them. x11vnc will not use them unless you specifically reference them. "HASHOFF" removes these HASH subdirs. .IP The LIST, LISTL, LL, ALL, HASHON, HASHOFF words can also be lowercase, e.g. "list". .PP \fB-sslDelCert\fR \fIpem\fR .IP Prompts you to delete all .crt .pem .key .req files associated with [pem]. x11vnc then exits. "SAVE" and lookups as in \fB-sslCertInfo\fR apply as well. .PP \fB-sslScripts\fR .IP Prints out both the 'genCA' and 'genCert' x11vnc openssl wrapper scripts for you to examine, modify, etc. The scripts are printed to stdout and then the x11vnc program exits. .PP \fB-stunnel\fR \fI[pem]\fR .IP Use the .IR stunnel (8) (stunnel.mirt.net) to provide an encrypted SSL tunnel between viewers and x11vnc. .IP This external tunnel method was implemented prior to the integrated \fB-ssl\fR encryption described above. It still works well and avoids the requirement of linking with the OpenSSL libraries. This mode requires stunnel to be installed on the system and available via PATH (n.b. stunnel is often installed in sbin directories). Version 4.x of stunnel is assumed (but see \fB-stunnel3\fR below.) .IP [pem] is optional, use "\fB-stunnel\fR \fI/path/to/stunnel.pem\fR" to specify a PEM certificate file to pass to stunnel. See the \fB-ssl\fR option for more info on certificate files. .IP Whether or not your stunnel has its own certificate depends on your stunnel configuration; stunnel often generates one at install time. See your stunnel documentation for details. In any event, if you want to use this certificate you must supply the full path to it as [pem]. Note: the file may only be readable by root. .IP [pem] may also be the special strings "TMP", "SAVE", and "SAVE..." as described in the \fB-ssl\fR option. If [pem] is not supplied, "SAVE" is assumed. .IP Note that the VeNCrypt, ANONTLS, and "ANON" modes are not supported in \fB-stunnel\fR mode. .IP stunnel is started up as a child process of x11vnc and any SSL connections stunnel receives are decrypted and sent to x11vnc over a local socket. The strings "The SSL VNC desktop is ..." and "SSLPORT=..." are printed out at startup to indicate this. .IP The \fB-localhost\fR option is enforced by default to avoid people routing around the SSL channel. Use \fB-env\fR STUNNEL_DISABLE_LOCALHOST=1 to disable this security requirement. .IP Set \fB-env\fR STUNNEL_DEBUG=1 for more debugging printout. .IP Set \fB-env\fR STUNNEL_PROG=xxx to the full path of stunnel program you want to be used (e.g. /usr/bin/stunnel4). .IP Set \fB-env\fR STUNNEL_LISTEN=xxx to the address of the network interface to listen on (the default is to listen on all interfaces), e.g. STUNNEL_LISTEN=192.168.1.100. .IP A simple way to add IPv6 support is STUNNEL_LISTEN=:: .IP Your VNC viewer will also need to be able to connect via SSL. Unfortunately not too many do this. See the information about SSL viewers under the \fB-ssl\fR option. The x11vnc project's SSVNC is an option. .IP Also, in the x11vnc distribution, patched TightVNC and UltraVNC Java applet jar files are provided in the classes/ssl directory that do SSL connections. Enable serving them with the \fB-http,\fR \fB-http_ssl,\fR or \fB-httpdir\fR (see the option descriptions for more info.) .IP Note that for the Java viewer applet usage the "?PORT=xxxx" in the various URLs printed at startup will need to be supplied to the web browser to connect properly. .IP Currently the automatic "single port" HTTPS mode of \fB-ssl\fR is not fully supported in \fB-stunnel\fR mode. However, it can be emulated via: .IP % x11vnc \fB-stunnel\fR \fB-http_ssl\fR \fB-http_oneport\fR ... .IP In general, it is also not too difficult to set up an stunnel or other SSL tunnel on the viewer side. A simple example on Unix using stunnel 3.x is: .IP % stunnel \fB-c\fR \fB-d\fR localhost:5901 \fB-r\fR remotehost:5900 % vncviewer localhost:1 .IP For Windows, stunnel has been ported to it and there are probably other such tools available. See the FAQ and SSVNC for more examples. .PP \fB-stunnel3\fR \fI[pem]\fR .IP Use version 3.x stunnel command line syntax instead of version 4.x. The \fB-http/-httpdir\fR Java applet serving is currently not available in this mode. .PP \fB-enc\fR \fIcipher:keyfile\fR .IP Use symmetric encryption with cipher "cipher" and secret key data in "keyfile". If keyfile is pw=<string> then "string" is used as the key data. .IP NOTE: It is recommended that you use SSL via the \fB-ssl\fR option instead of this option because SSL is well understood and takes great care to establish unique session keys and is more compatible with other software. Use this option if you do not want to deal with SSL certificates for authentication and do not want to use SSH but want some encryption for your VNC session. Or if you must interface with a symmetric key tunnel that you do not have control over. .IP Note that this mode will NOT work with the UltraVNC DSM plugins because they alter the RFB protocol in addition to tunnelling with the symmetric cipher (an unfortunate choice of implementation...) .IP cipher can be one of: arc4, aesv2, aes-cfb, blowfish, aes256, or 3des. See the OpenSSL documentation for more info. The keysize is 128 bits (except for aes256). Here is one way to make a keyfile with that many bits: .IP dd if=/dev/random of=./my.key bs=16 count=1 .IP you will need to securely share this key with the other side of the VNC connection (See SSVNC for examples). .IP Example: \fB-enc\fR blowfish:./my.key Example: \fB-enc\fR blowfish:pw=swordfish .IP By default 16 bytes of random salt followed by 16 bytes of random initialization vector are sent at the very beginning of the stream. The other side must read these and initialize their cipher with them. These values make the session key unique (without them the security is minimal). Similarly, the other side must send us its random salt and IV with those same lengths. .IP The salt and key data are combined to create a session key using an md5 hash as described in .IR EVP_BytesToKey (3). .IP The exact call is: EVP_BytesToKey(Cipher, EVP_md5(), salt, keydata, len, 1, keystr, NULL); where salt is the random data as described above, and keydata is the shared secret key data. keystr is the resulting session key. The cipher is then seeded with keystr and uses the random initialization vector as its first block. .IP To modify the amount of random salt and initialization vector use cipher@n,m where n is the salt length and m the initialization vector length. E.g. .IP \fB-enc\fR aes-cfb@8,16:./my.key .IP It is not a good idea to set either one to zero, although you may be forced to if the other side of the tunnel is not under your control. .IP To skip the salt and EVP_BytesToKey MD5 entirely (no hashing is done: the keydata is directly inserted into the cipher) specify "-1" for the salt, e.g. .IP \fB-enc\fR blowfish@-1,16:./my.key .IP The message digest can also be changed to something besides the default MD5. Use cipher@md+n,m where "md" can be one of sha, sha1, md5, or ripe. For example: .IP \fB-enc\fR arc4@sha+8,16:./my.key .IP The SSVNC vnc viewer project supplies a symmetric encryption tool named "ultravnc_dsm_helper" that can be used on the viewer side. For example: .IP ssvncviewer exec='ultravnc_dsm_helper arc4 my.key 0 h:p' .IP where h:p is the hostname and port of the x11vnc server. ultravnc_dsm_helper may also be used standalone to provide a symmetric encryption tunnel for any viewer or server (VNC or otherwise.) The cipher (1st arg) is basically the same syntax as we use above. .IP Also see the 'Non-Ultra DSM' SSVNC option for the \(aqUltraVNC DSM Encryption Plugin\(aq advanced option. .IP For both ways of using the viewer, you can specify the salt,ivec sizes (in GUI or, e.g. arc4@8,16). .PP \fB-https\fR \fI[port]\fR .IP Use a special, separate HTTPS port (-ssl and \fB-stunnel\fR modes only) for HTTPS Java viewer applet downloading. I.e. not 5900 and not 5800 (the defaults.) .IP BACKGROUND: In \fB-ssl\fR mode, it turns out you can use the single VNC port (e.g. 5900) for both VNC and HTTPS connections. (HTTPS is used to retrieve a SSL-aware VncViewer.jar applet that is provided with x11vnc). Since both use SSL the implementation was extended to detect if HTTP traffic (i.e. GET) is taking place and handle it accordingly. The URL would be, e.g.: .IP https://mymachine.org:5900/ .IP This is convenient for firewalls, etc, because only one port needs to be allowed in. However, this heuristic adds a few seconds delay to each connection and can be unreliable (especially if the user takes much time to ponder the Certificate dialogs in his browser, Java VM, or VNC Viewer applet. That's right 3 separate "Are you sure you want to connect?" dialogs!) .IP END OF BACKGROUND. .IP USAGE: So use the \fB-https\fR option to provide a separate, more reliable HTTPS port that x11vnc will listen on. If [port] is not provided (or is 0), one is autoselected. The URL to use is printed out at startup. .IP The SSL Java applet directory is specified via the \fB-httpdir\fR option. If not supplied, \fB-https\fR will try to guess the directory as though the \fB-http\fR option was supplied. .PP \fB-httpsredir\fR \fI[port]\fR .IP In \fB-ssl\fR mode with the Java applet retrieved via HTTPS, when the HTML file containing applet parameters ('index.vnc' or 'proxy.vnc') is sent do NOT set the applet PORT parameter to the actual VNC port but set it to "port" instead. If "port" is not supplied, then the port number is guessed from the Host: HTTP header. .IP This is useful when an incoming TCP connection redirection is performed by a router/gateway/firewall from one port to an internal machine where x11vnc is listening on a different port. The Java applet needs to connect to the firewall/router port, not the VNC port on the internal workstation. For example, one could redir from mygateway.com:443 to workstation:5900. .IP This spares the user from having to type in https://mygateway.com/?PORT=443 into their web browser. Note that port 443 is the default https port; other ports must be explicitly indicated, for example: https://mygateway.com:8000/?PORT=8000. To avoid having to include the PORT= in the browser URL, simply supply "\fB-httpsredir\fR" to x11vnc. .IP This option does not work in \fB-stunnel\fR mode. .IP More tricks: set the env var X11VNC_EXTRA_HTTPS_PARAMS to be extra URL parameters to use. This way you do not need to specify extra PARAMS in the index.vnc file. E.g. x11vnc \fB-env\fR X11VNC_EXTRA_HTTPS_PARAMS='?GET=1' ... .IP If you do not want to expose the non-SSL HTTP port to the network (i.e. you just want the single VNC/HTTPS port, e.g. 5900, open for connections) then specify the option \fB-env\fR X11VNC_HTTP_LISTEN_LOCALHOST=1 This way the connection to the LibVNCServer httpd server will only be available on localhost (note that in \fB-ssl\fR mode, HTTPS requests are redirected from SSL to the non-SSL LibVNCServer HTTP server.) .PP \fB-http_oneport\fR .IP For UN-encrypted connections mode (i.e. no \fB-ssl,\fR \fB-stunnel,\fR or \fB-enc\fR options), allow the Java VNC Viewer applet to be downloaded thru the VNC port via HTTP. .IP That is to say, you can use a single port for Java applet viewer connections by using a URL in your web browser like this, for example: .IP http://hostname:5900 .IP The regular, two-port mode, URL http://hostname:5800 will continue to work as well. .IP As mentioned above, this mode will NOT work with the \fB-ssl,\fR \fB-stunnel,\fR or \fB-enc\fR encryption options. Note that is it equivalent to '-enc none' (i.e. it uses the same detection mechanism as for HTTPS, but with no encryption.) .IP HTTPS single-port is on by default in \fB-ssl\fR encrypted mode (and \fB-enc\fR too), so you only need \fB-http_oneport\fR when doing non-SSL encrypted connections. .IP This mode could also be useful for SSH tunnels since it means only one port needs to be redirected. .IP The \fB-httpsredir\fR option may also be useful for this mode when using an SSH tunnel as well as for router port redirections. .IP Note that the \fB-env\fR X11VNC_HTTP_LISTEN_LOCALHOST=1 option described above under \fB-httpsredir\fR applies for the LibVNCServer httpd server in all cases (ssl or not.) .PP \fB-ssh\fR \fIuser@host:disp\fR .IP Create a remote listening port on machine "host" via a SSH tunnel using the \fB-R\fR rport:localhost:lport method. lport will be the local x11vnc listening port, so a connection to rport (5900+disp) on "host" will reach x11vnc. E.g. fred@snoopy.com:0 .IP This could be useful if a firewall/router prevents incoming connections to the x11vnc machine, but the ssh machine "host" can be reached by the VNC viewer. "user@" is not needed unless the remote unix username differs from the current one. .IP By default the remote sshd is usually configured to listen only on localhost for rport, so the viewer may need to ssh \fB-L\fR redir to "host" as well (See SSVNC to automate this). The sshd setting GatewayPorts enables listening on all interfaces for rport; viewers can reach it more easily. .IP "disp" is the VNC display for the remote SSH side, e.g. 0 corresponds to port 5900, etc. If disp is greater than 200 the value is used as the port. Use a negative value to force a low port, e.g. host:-80 will use port 80. .IP If ssh-agent is not active, then the ssh password needs to be entered in the terminal where x11vnc is running. .IP By default the remote ssh will issue a 'sleep 300' to wait for the incoming connection for 5 mins. To modify this use user@host:disp+secs. .IP If the remote SSH server is on a non-standard port (i.e. not 22) use user@host:port:disp+secs. .IP Note that the ssh process MAY NOT be killed when x11vnc exits. It tries by looking at .IR ps (1) output. .PP \fB-usepw\fR .IP If no other password method was supplied on the command line, first look for ~/.vnc/passwd and if found use it with \fB-rfbauth;\fR next, look for ~/.vnc/passwdfile and use it with \fB-passwdfile;\fR otherwise, prompt the user for a password to create ~/.vnc/passwd and use it with the \fB-rfbauth\fR option. If none of these succeed x11vnc exits immediately. .PP \fB-storepasswd\fR \fIpass\fR \fIfile\fR .IP Store password \fIpass\fR as the VNC password in the file \fIfile\fR. Once the password is stored the program exits. Use the password via "\fB-rfbauth\fR \fIfile\fR" .IP If called with no arguments, "x11vnc \fB-storepasswd",\fR the user is prompted for a password and it is stored in the file ~/.vnc/passwd. Called with one argument, that will be the file to store the prompted password in. .PP \fB-nopw\fR .IP Disable the big warning message when you use x11vnc without some sort of password. .PP \fB-accept\fR \fIstring\fR .IP Run a command (possibly to prompt the user at the X11 display) to decide whether an incoming client should be allowed to connect or not. \fIstring\fR is an external command run via .IR system (3) or some special cases described below. Be sure to quote \fIstring\fR if it contains spaces, shell characters, etc. If the external command returns 0 the client is accepted, otherwise the client is rejected. See below for an extension to accept a client view-only. .IP If x11vnc is running as root (say from .IR inetd (8) or from display managers .IR xdm (1) , .IR gdm (1) , etc), think about the security implications carefully before supplying this option (likewise for the \fB-gone\fR option). .IP Environment: The RFB_CLIENT_IP environment variable will be set to the incoming client IP number and the port in RFB_CLIENT_PORT (or -1 if unavailable). Similarly, RFB_SERVER_IP and RFB_SERVER_PORT (the x11vnc side of the connection), are set to allow identification of the tcp virtual circuit. The x11vnc process id will be in RFB_X11VNC_PID, a client id number in RFB_CLIENT_ID, and the number of other connected clients in RFB_CLIENT_COUNT. RFB_MODE will be "accept". RFB_STATE will be PROTOCOL_VERSION, SECURITY_TYPE, AUTHENTICATION, INITIALISATION, NORMAL, or UNKNOWN indicating up to which state the client has achieved. RFB_LOGIN_VIEWONLY will be 0, 1, or -1 (unknown). RFB_USERNAME, RFB_LOGIN_TIME, and RFB_CURRENT_TIME may also be set. .IP If \fIstring\fR is "popup" then a builtin popup window is used. The popup will time out after 120 seconds, use "popup:N" to modify the timeout to N seconds (use 0 for no timeout). .IP In the case of "popup" and when the \fB-unixpw\fR option is specified, then a *second* window will be popped up after the user successfully logs in via his UNIX password. This time the user will be identified as UNIX:username@hostname, the "UNIX:" prefix indicates which user the viewer logged as via \fB-unixpw.\fR The first popup is only for whether to allow him to even *try* to login via unix password. .IP If \fIstring\fR is "xmessage" then an .IR xmessage (1) invocation is used for the command. xmessage must be installed on the machine for this to work. .IP Both "popup" and "xmessage" will present an option for accepting the client "View-Only" (the client can only watch). This option will not be presented if \fB-viewonly\fR has been specified, in which case the entire display is view only. .IP If the user supplied command is prefixed with something like "yes:0,no:*,view:3 mycommand ..." then this associates the numerical command return code with the actions: accept, reject, and accept-view-only, respectively. Use "*" instead of a number to indicate the default action (in case the command returns an unexpected value). E.g. "no:*" is a good choice. .IP Note that x11vnc blocks while the external command or popup is running (other clients may see no updates during this period). So a person sitting a the physical display is needed to respond to an popup prompt. (use a 2nd x11vnc if you lock yourself out). .IP More \fB-accept\fR tricks: use "popupmouse" to only allow mouse clicks in the builtin popup to be recognized. Similarly use "popupkey" to only recognize keystroke responses. These are to help avoid the user accidentally accepting a client by typing or clicking. All 3 of the popup keywords can be followed by +N+M to supply a position for the popup window. The default is to center the popup window. .PP \fB-afteraccept\fR \fIstring\fR .IP As \fB-accept,\fR except to run a user supplied command after a client has been accepted and authenticated. RFB_MODE will be set to "afteraccept" and the other RFB_* variables are as in \fB-accept.\fR Unlike \fB-accept,\fR the command return code is not interpreted by x11vnc. Example: \fB-afteraccept\fR 'killall xlock &' .PP \fB-gone\fR \fIstring\fR .IP As \fB-accept,\fR except to run a user supplied command when a client goes away (disconnects). RFB_MODE will be set to "gone" and the other RFB_* variables are as in \fB-accept.\fR The "popup" actions apply as well. Unlike \fB-accept,\fR the command return code is not interpreted by x11vnc. Example: \fB-gone\fR 'xlock &' .PP \fB-users\fR \fIlist\fR .IP If x11vnc is started as root (say from .IR inetd (8) or from display managers .IR xdm (1) , .IR gdm (1) , etc), then as soon as possible after connections to the X display are established try to switch to one of the users in the comma separated \fIlist\fR. If x11vnc is not running as root this option is ignored. .IP Why use this option? In general it is not needed since x11vnc is already connected to the X display and can perform its primary functions. The option was added to make some of the *external* utility commands x11vnc occasionally runs work properly. In particular under GNOME and KDE to implement the "\fB-solid\fR \fIcolor\fR" feature external commands (gconftool-2 and dcop) unfortunately must be run as the user owning the desktop session. Since this option switches userid it also affects the userid used to run the processes for the \fB-accept\fR and \fB-gone\fR options. It also affects the ability to read files for options such as \fB-connect,\fR \fB-allow,\fR and \fB-remap\fR and also the ultra and tight filetransfer feature if enabled. Note that the \fB-connect\fR file is also sometimes written to. .IP So be careful with this option since in some situations its use can decrease security. .IP In general the switch to a user will only take place if the display can still be successfully opened as that user (this is primarily to try to guess the actual owner of the session). Example: "\fB-users\fR \fIfred,wilma,betty\fR". Note that a malicious local user "barney" by quickly using "xhost +" when logging in may possibly get the x11vnc process to switch to user "fred". What happens next? .IP Under display managers it may be a long time before the switch succeeds (i.e. a user logs in). To instead make it switch immediately regardless if the display can be reopened prefix the username with the "+" character. E.g. "\fB-users\fR \fI+bob\fR" or "\fB-users\fR \fI+nobody\fR". .IP The latter (i.e. switching immediately to user "nobody") is the only obvious use of the \fB-users\fR option that increases security. .IP Use the following notation to associate a group with a user: user1.group1,user2.group2,... Note that .IR initgroups (2) will still be called first to try to switch to ALL of a user's groups (primary and additional groups). Only if that fails or it is not available then the single group specified as above (or the user's primary group if not specified) is switched to with .IR setgid (2). Use \fB-env\fR X11VNC_SINGLE_GROUP=1 to prevent trying .IR initgroups (2) and only switch to the single group. This sort of setting is only really needed to make the ultra or tight filetransfer permissions work properly. This format applies to any comma separated list of users, even the special "=" modes described below. .IP In \fB-unixpw\fR mode, if "\fB-users\fR \fIunixpw=\fR" is supplied then after a user authenticates himself via the \fB-unixpw\fR mechanism, x11vnc will try to switch to that user as though "\fB-users\fR \fI+username\fR" had been supplied. If you want to limit which users this will be done for, provide them as a comma separated list after "unixpw=" Groups can also be specified as described above. .IP Similarly, in \fB-ssl\fR mode, if "\fB-users\fR \fIsslpeer=\fR" is supplied then after an SSL client authenticates with his cert (the \fB-sslverify\fR option is required for this) x11vnc will extract a UNIX username from the "emailAddress" field (username@hostname.com) of the "Subject" of the x509 SSL cert and then try to switch to that user as though "\fB-users\fR \fI+username\fR" had been supplied. If you want to limit which users this will be done for, provide them as a comma separated list after "sslpeer=". Set the env. var X11VNC_SSLPEER_CN to use the Common Name (normally a hostname) instead of the Email field. .IP NOTE: for sslpeer= mode the x11vnc administrator must take care that any client certs he adds to \fB-sslverify\fR have the intended UNIX username in the "emailAddress" field of the cert. Otherwise a user may be able to log in as another. This command can be of use in checking: "openssl x509 \fB-text\fR \fB-in\fR file.crt", see the "Subject:" line. Also, along with the normal RFB_* env. vars. (see \fB-accept)\fR passed to external cmd= commands, RFB_SSL_CLIENT_CERT will be set to the client's x509 certificate string. .IP The sslpeer= mode can aid finding X sessions via the FINDDISPLAY and FINDCREATEDISPLAY mechanisms. .IP To immediately switch to a user *before* connections to the X display are made or any files opened use the "=" character: "\fB-users\fR \fI=bob\fR". That user needs to be able to open the X display and any files of course. .IP The special user "guess=" means to examine the utmpx database (see .IR who (1) ) looking for a user attached to the display number (from DISPLAY or \fB-display\fR option) and try him/her. To limit the list of guesses, use: "\fB-users\fR \fIguess=bob,betty\fR". .IP Even more sinister is the special user "lurk=" that means to try to guess the DISPLAY from the utmpx login database as well. So it "lurks" waiting for anyone to log into an X session and then connects to it. Specify a list of users after the = to limit which users will be tried. To enable a different searching mode, if the first user in the list is something like ":0" or ":0-2" that indicates a range of DISPLAY numbers that will be tried (regardless of whether they are in the utmpx database) for all users that are logged in. Also see the "\fB-display\fR \fIWAIT:...\fR" functionality. Examples: "\fB-users\fR \fIlurk=\fR" and also "\fB-users\fR \fIlurk=:0-1,bob,mary\fR" .IP Be especially careful using the "guess=" and "lurk=" modes. They are not recommended for use on machines with untrustworthy local users. .PP \fB-noshm\fR .IP Do not use the MIT-SHM extension for the polling. Remote displays can be polled this way: be careful this can use large amounts of network bandwidth. This is also of use if the local machine has a limited number of shm segments and \fB-onetile\fR is not sufficient. .PP \fB-flipbyteorder\fR .IP Sometimes needed if remotely polled host has different endianness. Ignored unless \fB-noshm\fR is set. .PP \fB-onetile\fR .IP Do not use the new copy_tiles() framebuffer mechanism, just use 1 shm tile for polling. Limits shm segments used to 3. .IP To disable any automatic shm reduction set the env. var. X11VNC_NO_LIMIT_SHM. .PP \fB-solid\fR \fI[color]\fR .IP To improve performance, when VNC clients are connected try to change the desktop background to a solid color. The [color] is optional: the default color is "cyan4". For a different one specify the X color (rgb.txt name, e.g. "darkblue" or numerical "#RRGGBB"). .IP Currently this option only works on GNOME, KDE, CDE, XFCE, and classic X (i.e. with the background image on the root window). The "gconftool-2", "dcop" and "xfconf-query" external commands are run for GNOME, KDE, and XFCE respectively. This also works on native MacOSX. (There is no color selection for MacOSX or XFCE.) Other desktops won't work, (send us the corresponding commands if you find them). If x11vnc is running as root ( .IR inetd (8) or .IR gdm (1) ), the \fB-users\fR option may be needed for GNOME, KDE, XFCE. If x11vnc guesses your desktop incorrectly, you can force it by prefixing color with "gnome:", "kde:", "cde:", "xfce:", or "root:". .IP Update: \fB-solid\fR no longer works on KDE4. .IP This mode works in a limited way on the Mac OS X Console with one color ('kelp') using the screensaver writing to the background. Look in "~/Library/Screen Savers" for VncSolidColor.png to change the color. .PP \fB-blackout\fR \fIstring\fR .IP Black out rectangles on the screen. \fIstring\fR is a comma separated list of WxH+X+Y type geometries for each rectangle. If one of the items on the list is the string "noptr" the mouse pointer will not be allowed to go into a blacked out region. .PP \fB-xinerama,\fR \fB-noxinerama\fR .IP If your screen is composed of multiple monitors glued together via XINERAMA, and that screen is not a rectangle this option will try to guess the areas to black out (if your system has libXinerama). default: \fB-xinerama\fR .IP In general, we have noticed on XINERAMA displays you may need to use the "\fB-xwarppointer\fR" option if the mouse pointer misbehaves and it is enabled by default. Use "\fB-noxwarppointer\fR" if you do not want this. .PP \fB-xtrap\fR .IP Use the DEC-XTRAP extension for keystroke and mouse input insertion. For use on legacy systems, e.g. X11R5, running an incomplete or missing XTEST extension. By default DEC-XTRAP will be used if XTEST server grab control is missing, use \fB-xtrap\fR to do the keystroke and mouse insertion via DEC-XTRAP as well. .PP \fB-xrandr\fR \fI[mode]\fR .IP If the display supports the XRANDR (X Resize, Rotate and Reflection) extension, and you expect XRANDR events to occur to the display while x11vnc is running, this options indicates x11vnc should try to respond to them (as opposed to simply crashing by assuming the old screen size). See the .IR xrandr (1) manpage and run \(aqxrandr \fB-q\(aq\fR for more info. [mode] is optional and described below. .IP Since watching for XRANDR events and trapping errors increases polling overhead, only use this option if XRANDR changes are expected. For example on a rotatable screen PDA or laptop, or using a XRANDR-aware Desktop where you resize often. It is best to be viewing with a vncviewer that supports the NewFBSize encoding, since it knows how to react to screen size changes. Otherwise, LibVNCServer tries to do so something reasonable for viewers that cannot do this (portions of the screen may be clipped, unused, etc). .IP Note: the default now is to check for XRANDR events, but do not trap every X call that may fail due to resize. If a resize event is received, the full \fB-xrandr\fR mode is enabled. To disable even checking for events supply: \fB-noxrandr.\fR .IP "mode" defaults to "resize", which means create a new, resized, framebuffer and hope all viewers can cope with the change. "newfbsize" means first disconnect all viewers that do not support the NewFBSize VNC encoding, and then resize the framebuffer. "exit" means disconnect all viewer clients, and then terminate x11vnc. .PP \fB-rotate\fR \fIstring\fR .IP Rotate and/or flip the framebuffer view exported by VNC. This transformation is independent of XRANDR and is done in software in main memory and so may be slower. This mode could be useful on a handheld with portrait or landscape modes that do not correspond to the scanline order of the actual framebuffer. \fIstring\fR can be: .IP x flip along x-axis y flip along y-axis xy flip along x- and y-axes +90 rotate 90 degrees clockwise \fB-90\fR rotate 90 degrees counter-clockwise +90x rotate 90 degrees CW, then flip along x +90y rotate 90 degrees CW, then flip along y .IP these give all possible rotations and reflections. .IP Aliases: same as xy: yx, +180, \fB-180,\fR 180 same as \fB-90:\fR +270, 270 same as +90: 90, (ditto for 90x, 90y) .IP Like \fB-scale,\fR this transformation is applied at the very end of any chain of framebuffer transformations and so any options with geometries, e.g. \fB-blackout,\fR \fB-clip,\fR etc. are relative to the original X (or \fB-rawfb)\fR framebuffer, not the final one sent to VNC viewers. .IP If you do not want the cursor shape to be rotated prefix \fIstring\fR with "nc:", e.g. "nc:+90", "nc:xy", etc. .PP \fB-padgeom\fR \fIWxH\fR .IP Whenever a new vncviewer connects, the framebuffer is replaced with a fake, solid black one of geometry WxH. Shortly afterwards the framebuffer is replaced with the real one. This is intended for use with vncviewers that do not support NewFBSize and one wants to make sure the initial viewer geometry will be big enough to handle all subsequent resizes (e.g. under \fB-xrandr,\fR \fB-remote\fR id:windowid, rescaling, etc.) .IP In \fB-unixpw\fR mode this sets the size of the login screen. Use "once:WxH" it ignore padgeom after the login screen is set up. .PP \fB-o\fR \fIlogfile\fR .IP Write stderr messages to file \fIlogfile\fR instead of to the terminal. Same as "\fB-logfile\fR \fIfile\fR". To append to the file use "\fB-oa\fR \fIfile\fR" or "\fB-logappend\fR \fIfile\fR". If \fIlogfile\fR contains the string "%VNCDISPLAY" it is expanded to the vnc display (the name may need to be guessed at.) "%HOME" works too. .PP \fB-flag\fR \fIfile\fR .IP Write the "PORT=NNNN" (e.g. PORT=5900) string to \fIfile\fR in addition to stdout. This option could be useful by wrapper script to detect when x11vnc is ready. .PP \fB-rmflag\fR \fIfile\fR .IP Remove \fIfile\fR at exit to signal when x11vnc is done. The file is created at startup if it does not already exist or if \fIfile\fR is prefixed with "create:". If the file is created, the x11vnc PID is placed in the file. Otherwise the files contents is not changed. Use prefix "nocreate:" to prevent creation. .PP \fB-rc\fR \fIfilename\fR .IP Use \fIfilename\fR instead of $HOME/.x11vncrc for rc file. .PP \fB-norc\fR .IP Do not process any .x11vncrc file for options. .PP \fB-env\fR \fIVAR=VALUE\fR .IP Set the environment variable 'VAR' to value 'VALUE' at x11vnc startup. This is a convenience utility to avoid shell script wrappers, etc. to set the env. var. You may specify as many of these as needed on the command line. .PP \fB-prog\fR \fI/path/to/x11vnc\fR .IP Set the full path to the x11vnc program for cases when it cannot be determined from argv[0] (e.g. tcpd/inetd) .PP \fB-h,\fR \fB-help\fR .IP Print this help text. -?, \fB-opts\fR Only list the x11vnc options. .PP \fB-V,\fR \fB-version\fR .IP Print program version and last modification date. .PP \fB-license\fR .IP Print out license information. Same as \fB-copying\fR and \fB-warranty.\fR .PP \fB-dbg\fR .IP Instead of exiting after cleaning up, run a simple "debug crash shell" when fatal errors are trapped. .PP \fB-q,\fR \fB-quiet\fR .IP Be quiet by printing less informational output to stderr. (use \fB-noquiet\fR to undo an earlier \fB-quiet.)\fR .IP The \fB-quiet\fR option does not eliminate all informational output, it only reduces it. It is ignored in most auxiliary usage modes, e.g. \fB-storepasswd.\fR To eliminate all output use: 2>/dev/null 1>&2, etc. .PP \fB-v,\fR \fB-verbose\fR .IP Print out more information to stderr. .PP \fB-bg\fR .IP Go into the background after screen setup. Messages to stderr are lost unless \fB-o\fR logfile is used. Something like this could be useful in a script: .IP port=`ssh -t $host "x11vnc -display :0 -bg" | grep PORT` .IP port=`echo "$port" | sed -e 's/PORT=//'` .IP port=`expr $port - 5900` .IP vncviewer $host:$port .PP \fB-modtweak,\fR \fB-nomodtweak\fR .IP Option \fB-modtweak\fR automatically tries to adjust the AltGr and Shift modifiers for differing language keyboards between client and host. Otherwise, only a single key press/release of a Keycode is simulated (i.e. ignoring the state of the modifiers: this usually works for identical keyboards). Also useful in resolving cases where a Keysym is bound to multiple keys (e.g. "<" + ">" and "," + "<" keys). Default: \fB-modtweak\fR .IP If you are having trouble with with keys and \fB-xkb\fR or \fB-noxkb,\fR and similar things don't help, try \fB-nomodtweak.\fR .IP On some HP-UX systems it is been noted that they have an odd keymapping where a single keycode will have a keysym, e.g. "#", up to three times. You can check via "xmodmap \fB-pk"\fR or the \fB-dk\fR option. The failure is when you try to type "#" it yields "3". If you see this problem try setting the environment variable MODTWEAK_LOWEST=1 to see if it helps. .PP \fB-xkb,\fR \fB-noxkb\fR .IP When in modtweak mode, use the XKEYBOARD extension (if the X display supports it) to do the modifier tweaking. This is powerful and should be tried if there are still keymapping problems when using \fB-modtweak\fR by itself. The default is to check whether some common keysyms, e.g. !, @, [, are only accessible via \fB-xkb\fR mode and if so then automatically enable the mode. To disable this automatic detection use \fB-noxkb.\fR .IP When \fB-xkb\fR mode is active you can set these env. vars. They apply only when there is ambiguity as to which key to choose (i.e the mapping is not one-to-one). NOKEYHINTS=1: for up ascii keystrokes do not use score hints saved when the key was pressed down. NOANYDOWN=1: for up keystrokes do not resort to searching through keys that are currently pressed down. KEYSDOWN=N: remember the last N keys press down for tie-breaking when an up keystroke comes in. .PP \fB-capslock\fR .IP When in \fB-modtweak\fR (the default) or \fB-xkb\fR mode, if a keysym in the range A-Z comes in check the X server to see if the Caps_Lock is set. If it is do not artificially press Shift to generate the keysym. This will enable the CapsLock key to behave correctly in some circumstances: namely *both* the VNC viewer machine and the x11vnc X server are in the CapsLock on state. If one side has CapsLock on and the other off and the keyboard is not behaving as you think it should you should correct the CapsLock states (hint: pressing CapsLock inside and outside of the viewer can help toggle them both to the correct state). However, for best results do not use this option, but rather *only* enable CapsLock on the VNC viewer side (i.e. by pressing CapsLock outside of the viewer window, also \fB-skip_lockkeys\fR below). Also try \fB-nomodtweak\fR for a possible workaround. .PP \fB-skip_lockkeys,\fR \fB-noskip_lockkeys\fR .IP Have x11vnc ignore all Caps_Lock, Shift_Lock, Num_Lock, Scroll_Lock keysyms received from viewers. The idea is you press Caps_Lock on the VNC Viewer side but that does not change the lock state in the x11vnc-side X server. Nevertheless your capitalized letters come in over the wire and are applied correctly to the x11vnc-side X server. Note this mode probably won't do what you want in \fB-nomodtweak\fR mode. Also, a kludge for KP_n digits is always done in this mode: they are mapped to regular digit keysyms. See also \fB-capslock\fR above. The default is \fB-noskip_lockkeys.\fR .PP \fB-skip_keycodes\fR \fIstring\fR .IP Ignore the comma separated list of decimal keycodes. Perhaps these are keycodes not on your keyboard but your X server thinks exist. Currently only applies to \fB-xkb\fR mode. Use this option to help x11vnc in the reverse problem it tries to solve: Keysym -> Keycode(s) when ambiguities exist (more than one Keycode per Keysym). Run 'xmodmap \fB-pk'\fR to see your keymapping. Example: "\fB-skip_keycodes\fR \fI94,114\fR" .PP \fB-sloppy_keys\fR .IP Experimental option that tries to correct some "sloppy" key behavior. E.g. if at the viewer you press Shift+Key but then release the Shift before Key that could give rise to extra unwanted characters (usually only between keyboards of different languages). Only use this option if you observe problems with some keystrokes. .PP \fB-skip_dups,\fR \fB-noskip_dups\fR .IP Some VNC viewers send impossible repeated key events, e.g. key-down, key-down, key-up, key-up all for the same key, or 20 downs in a row for the same modifier key! Setting \fB-skip_dups\fR means to skip these duplicates and just process the first event. Note: some VNC viewers assume they can send down's without the corresponding up's and so you should not set this option for these viewers (symptom: some keys do not autorepeat) Default: \fB-noskip_dups\fR .PP \fB-add_keysyms,\fR \fB-noadd_keysyms\fR .IP If a Keysym is received from a VNC viewer and that Keysym does not exist in the X server, then add the Keysym to the X server's keyboard mapping on an unused key. Added Keysyms will be removed periodically and also when x11vnc exits. Default: \fB-add_keysyms\fR .PP \fB-clear_mods\fR .IP At startup and exit clear the modifier keys by sending KeyRelease for each one. The Lock modifiers are skipped. Used to clear the state if the display was accidentally left with any pressed down. .PP \fB-clear_keys\fR .IP As \fB-clear_mods,\fR except try to release ANY pressed key. Note that this option and \fB-clear_mods\fR can interfere with a person typing at the physical keyboard. .PP \fB-clear_all\fR .IP As \fB-clear_keys,\fR except try to release any CapsLock, NumLock, etc. locks as well. .PP \fB-remap\fR \fIstring\fR .IP Read Keysym remappings from file named \fIstring\fR. Format is one pair of Keysyms per line (can be name or hex value) separated by a space. If no file named \fIstring\fR exists, it is instead interpreted as this form: key1-key2,key3-key4,... See <X11/keysymdef.h> header file for a list of Keysym names, or use .IR xev (1). .IP To map a key to a button click, use the fake Keysyms "Button1", ..., etc. E.g: "\fB-remap\fR \fISuper_R-Button2\fR" (useful for pasting on a laptop) .IP I use these if the machine I am viewing from does not have a scrollwheel or I don't like using the one it has: .IP \fB-remap\fR Super_R-Button4,Menu-Button5 \fB-remap\fR KP_Add-Button4,KP_Enter-Button5 .IP the former would be used on a PC, the latter on a MacBook. This way those little used keys can be used to generate bigger hops than the Up and Down arrows provide. One can scroll through text or web pages more quickly this way (especially if x11vnc scroll detection is active.) .IP Use Button44, Button12, etc. for multiple clicks. .IP To disable a keysym (i.e. make it so it will not be injected), remap it to "NoSymbol" or "None". .IP Dead keys: "dead" (or silent, mute) keys are keys that do not produce a character but must be followed by a 2nd keystroke. This is often used for accenting characters, e.g. to put "`" on top of "a" by pressing the dead key and then "a". Note that this interpretation is not part of core X11, it is up to the toolkit or application to decide how to react to the sequence. The X11 names for these keysyms are "dead_grave", "dead_acute", etc. However some VNC viewers send the keysyms "grave", "acute" instead thereby disabling the accenting. To work around this \fB-remap\fR can be used. For example "\fB-remap\fR \fIgrave-dead_grave,acute-dead_acute\fR" .IP As a convenience, "\fB-remap\fR \fIDEAD\fR" applies these remaps: .IP g grave-dead_grave a acute-dead_acute c asciicircum-dead_circumflex t asciitilde-dead_tilde m macron-dead_macron b breve-dead_breve D abovedot-dead_abovedot d diaeresis-dead_diaeresis o degree-dead_abovering A doubleacute-dead_doubleacute r caron-dead_caron e cedilla-dead_cedilla .IP .IP If you just want a subset use the first letter label, e.g. "\fB-remap\fR \fIDEAD=ga\fR" to get the first two. Additional remaps may also be supplied via commas, e.g. "\fB-remap\fR \fIDEAD=ga,Super_R-Button2\fR". Finally, "DEAD=missing" means to apply all of the above as long as the left hand member is not already in the X11 keymap. .PP \fB-norepeat,\fR \fB-repeat\fR .IP Option \fB-norepeat\fR disables X server key auto repeat when VNC clients are connected and VNC keyboard input is not idle for more than 5 minutes. This works around a repeating keystrokes bug (triggered by long processing delays between key down and key up client events: either from large screen changes or high latency). Default: \fB-norepeat\fR .IP You can set the env. var. X11VNC_IDLE_TIMEOUT to the number of idle seconds you want (5min = 300secs). .IP Note: your VNC viewer side will likely do autorepeating, so this is no loss unless someone is simultaneously at the real X display. .IP Use "\fB-norepeat\fR \fIN\fR" to set how many times norepeat will be reset if something else (e.g. X session manager) undoes it. The default is 2. Use a negative value for unlimited resets. .PP \fB-nofb\fR .IP Ignore video framebuffer: only process keyboard and pointer. Intended for use with Win2VNC and x2vnc dual-monitor setups. .PP \fB-nobell\fR .IP Do not watch for XBell events. (no beeps will be heard) Note: XBell monitoring requires the XKEYBOARD extension. .PP \fB-nosel\fR .IP Do not manage exchange of X selection/cutbuffer between VNC viewers and the X server at all. .PP \fB-noprimary\fR .IP Do not poll the PRIMARY selection for changes to send back to clients. (PRIMARY is still set on received changes, however). .PP \fB-nosetprimary\fR .IP Do not set the PRIMARY selection for changes received from VNC clients. .PP \fB-noclipboard\fR .IP Do not poll the CLIPBOARD selection for changes to send back to clients. (CLIPBOARD is still set on received changes, however). .PP \fB-nosetclipboard\fR .IP Do not set the CLIPBOARD selection for changes received from VNC clients. .PP \fB-seldir\fR \fIstring\fR .IP If direction string is "send", only send the selection to viewers, and if it is "recv" only receive it from viewers. To work around apps setting the selection too frequently and messing up the other end. You can actually supply a comma separated list of directions, including "debug" to turn on debugging output. .PP \fB-cursor\fR \fI[mode],\fR \fB-nocursor\fR .IP Sets how the pointer cursor shape (little icon at the mouse pointer) should be handled. The "mode" string is optional and is described below. The default is to show some sort of cursor shape(s). How this is done depends on the VNC viewer and the X server. Use \fB-nocursor\fR to disable cursor shapes completely. .IP Some VNC viewers support the TightVNC CursorPosUpdates and CursorShapeUpdates extensions (cuts down on network traffic by not having to send the cursor image every time the pointer is moved), in which case these extensions are used (see \fB-nocursorshape\fR and \fB-nocursorpos\fR below to disable). For other viewers the cursor shape is written directly to the framebuffer every time the pointer is moved or changed and gets sent along with the other framebuffer updates. In this case, there will be some lag between the vnc viewer pointer and the remote cursor position. .IP If the X display supports retrieving the cursor shape information from the X server, then the default is to use that mode. On Solaris this can be done with the SUN_OVL extension using \fB-overlay\fR (see also the \fB-overlay_nocursor\fR option). A similar overlay scheme is used on IRIX. Xorg (e.g. Linux) and recent Solaris Xsun servers support the XFIXES extension to retrieve the exact cursor shape from the X server. If XFIXES is present it is preferred over Overlay and is used by default (see \fB-noxfixes\fR below). This can be disabled with \fB-nocursor,\fR and also some values of the "mode" option below. .IP Note that under XFIXES cursors with transparency (alpha channel) will usually not be exactly represented and one may find Overlay preferable. See also the \fB-alphacut\fR and \fB-alphafrac\fR options below as fudge factors to try to improve the situation for cursors with transparency for a given theme. .IP The "mode" string can be used to fine-tune the displaying of cursor shapes. It can be used the following ways: .IP "\fB-cursor\fR \fIarrow\fR" - just show the standard arrow nothing more or nothing less. .IP "\fB-cursor\fR \fInone\fR" - same as "\fB-nocursor\fR" .IP "\fB-cursor\fR \fIX\fR" - when the cursor appears to be on the root window, draw the familiar X shape. Some desktops such as GNOME cover up the root window completely, and so this will not work, try "X1", etc, to try to shift the tree depth. On high latency links or slow machines there will be a time lag between expected and the actual cursor shape. .IP "\fB-cursor\fR \fIsome\fR" - like "X" but use additional heuristics to try to guess if the window should have a windowmanager-like resizer cursor or a text input I-beam cursor. This is a complete hack, but may be useful in some situations because it provides a little more feedback about the cursor shape. .IP "\fB-cursor\fR \fImost\fR" - try to show as many cursors as possible. Often this will only be the same as "some" unless the display has overlay visuals or XFIXES extensions available. On Solaris and IRIX if XFIXES is not available, \fB-overlay\fR mode will be attempted. .PP \fB-cursor_drag\fR .IP Show cursor shape changes even when the mouse is being dragged with a mouse button down. This is useful if you want to be able to see Drag-and-Drop cursor icons, etc. .PP \fB-arrow\fR \fIn\fR .IP Choose an alternate "arrow" cursor from a set of some common ones. n can be 1 to 6. Default is: 1 Ignored when in XFIXES cursor-grabbing mode. .PP \fB-noxfixes\fR .IP Do not use the XFIXES extension to draw the exact cursor shape even if it is available. .IP Note: To work around a crash in Xorg 1.5 and later some people needed to use \fB-noxfixes.\fR The Xorg crash occurred right after a Display Manager (e.g. GDM) login. Starting with x11vnc 0.9.9 it tries to automatically avoid using XFIXES until it is sure a window manager is running. See the \fB-reopen\fR option for more info and how to use X11VNC_AVOID_WINDOWS=never to disable it. .PP \fB-alphacut\fR \fIn\fR .IP When using the XFIXES extension for the cursor shape, cursors with transparency will not usually be displayed exactly (but opaque ones will). This option sets n as a cutoff for cursors that have transparency ("alpha channel" with values ranging from 0 to 255) Any cursor pixel with alpha value less than n becomes completely transparent. Otherwise the pixel is completely opaque. Default 240 .PP \fB-alphafrac\fR \fIfraction\fR .IP With the threshold in \fB-alphacut\fR some cursors will become almost completely transparent because their alpha values are not high enough. For those cursors adjust the alpha threshold until fraction of the non-zero alpha channel pixels become opaque. Default 0.33 .PP \fB-alpharemove\fR .IP By default, XFIXES cursors pixels with transparency have the alpha factor multiplied into the RGB color values (i.e. that corresponding to blending the cursor with a black background). Specify this option to remove the alpha factor. (useful for light colored semi-transparent cursors). .PP \fB-noalphablend\fR .IP In XFIXES mode do not send cursor alpha channel data to LibVNCServer. The default is to send it. The alphablend effect will only be visible in \fB-nocursorshape\fR mode or for clients with cursorshapeupdates turned off. (However there is a hack for 32bpp with depth 24, it uses the extra 8 bits to store cursor transparency for use with a hacked vncviewer that applies the transparency locally. See the FAQ for more info). .PP \fB-nocursorshape\fR .IP Do not use the TightVNC CursorShapeUpdates extension even if clients support it. See \fB-cursor\fR above. .PP \fB-cursorpos,\fR \fB-nocursorpos\fR .IP Option \fB-cursorpos\fR enables sending the X cursor position back to all vnc clients that support the TightVNC CursorPosUpdates extension. Other clients will be able to see the pointer motions. Default: \fB-cursorpos\fR .PP \fB-xwarppointer,\fR \fB-noxwarppointer\fR .IP Move the pointer with .IR XWarpPointer (3X) instead of the XTEST extension. Use this as a workaround if the pointer motion behaves incorrectly, e.g. on touchscreens or other non-standard setups. .IP It is also sometimes needed on XINERAMA displays and is enabled by default if XINERAMA is found to be active. To prevent this, use \fB-noxwarppointer.\fR .PP \fB-always_inject\fR .IP Even if there is no displacement (dx = dy = 0) for a VNC mouse event force the pointer to the indicated x,y position anyway. Recent (2009) gui toolkits (gnome) have problems with x11vnc's original mouse input injection method. So x11vnc's mouse input injection method has been modified. To regain the OLD behavior use this option: \fB-always_inject.\fR Then x11vnc will always force positioning the mouse to the x,y position even if that position has not changed since the previous VNC input event. .IP The first place this problem was noticed was in gnome terminal: if you pressed and released mouse button 3, a menu was posted and then its first element 'New Terminal Window' was activated. This was because x11vnc injected the mouse position twice: once on ButtonPress and again on ButtonRelease. The toolkit interpreted the 2nd one as mouse motion even though the mouse hadn't moved. So now by default x11vnc tries to avoid injecting the 2nd one. .IP Note that with the new default x11vnc will be oblivious to applications moving the pointer (warping) or the user at the physical display moving it. So it might, e.g., inject ButtonRelease at the wrong position. If this (or similar scenarios) causes problems in your environment, specify \fB-always_inject\fR for the old method. .PP \fB-buttonmap\fR \fIstring\fR .IP String to remap mouse buttons. Format: IJK-LMN, this maps buttons I -> L, etc., e.g. \fB-buttonmap\fR 13-31 .IP Button presses can also be mapped to keystrokes: replace a button digit on the right of the dash with :<sym>: or :<sym1>+<sym2>: etc. for multiple keys. For example, if the viewing machine has a mouse-wheel (buttons 4 5) but the x11vnc side does not, these will do scrolls: .IP \fB-buttonmap\fR 12345-123:Prior::Next: .IP \fB-buttonmap\fR 12345-123:Up+Up+Up::Down+Down+Down: .IP See <X11/keysymdef.h> header file for a list of Keysyms, or use the .IR xev (1) program. Note: mapping of button clicks to Keysyms may not work if \fB-modtweak\fR or \fB-xkb\fR is needed for the Keysym. .IP If you include a modifier like "Shift_L" the modifier's up/down state is toggled, e.g. to send "The" use :Shift_L+t+Shift_L+h+e: (the 1st one is shift down and the 2nd one is shift up). (note: the initial state of the modifier is ignored and not reset) To include button events use "Button1", ... etc. .IP .IP \fB-buttonmap\fR currently does not work on MacOSX console or in \fB-rawfb\fR mode. .IP Workaround: use \fB-buttonmap\fR IJ...-LM...=n to limit the number of mouse buttons to n, e.g. 123-123=3. This will prevent x11vnc from crashing if the X server reports there are 5 buttons (4/5 scroll wheel), but there are only really 3. .PP \fB-nodragging\fR .IP Do not update the display during mouse dragging events (mouse button held down). Greatly improves response on slow setups, but you lose all visual feedback for drags, text selection, and some menu traversals. It overrides any \fB-pointer_mode\fR setting. .PP \fB-ncache\fR \fIn\fR .IP Client-side caching scheme. Framebuffer memory \fIn\fR (an integer) times that of the full display is allocated below the actual framebuffer to cache screen contents for rapid retrieval. So a W x H frambuffer is expanded to a W x (n+1)*H one. Use 0 to disable. .IP The \fIn\fR is actually optional, the default is 10. .IP For this and the other \fB-ncache*\fR options below you can abbreviate "\fB-ncache\fR" with "\fB-nc\fR". Also, "\fB-nonc\fR" is the same as "\fB-ncache\fR \fI0\fR" .IP This is an experimental option, currently implemented in an awkward way in that in the VNC Viewer you can see the pixel cache contents if you scroll down, etc. So you will have to set things up so you can't see that region. If this method is successful, the changes required for clients to do this less awkwardly will be investigated. .IP The SSVNC viewer does a good job at automatically hiding the pixel cache region. Or use SSVNC's \fB-ycrop\fR option to explicitly hide the region. .IP Note that this mode consumes a huge amount of memory, both on the x11vnc server side and on the VNC Viewer side. If n=2 then the amount of RAM used is roughly tripled for both x11vnc and the VNC Viewer. As a rule of thumb, note that 1280x1024 at depth 24 is about 5MB of pixel data. .IP For reasonable response when cycling through 4 to 6 large (e.g. web browser) windows a value n of 6 to 12 is recommended. (that's right: ~10X more memory...) .IP Because of the way window backingstore and saveunders are implemented, n must be even. It will be incremented by 1 if it is not. .IP This mode also works for native MacOS X, but may not be as effective as the X version. This is due to a number of things, one is the drop-shadow compositing that leaves extra areas that need to be repaired (see \fB-ncache_pad).\fR Another is the window iconification animations need to be avoided (see \fB-macicontime).\fR It appears the that the 'Scale' animation mode gives better results than the 'Genie' one. Also, window event detection not as accurate as the X version. .PP \fB-ncache_cr\fR .IP In \fB-ncache\fR mode, try to do copyrect opaque window moves/drags instead of wireframes (this can induce painting errors). The wireframe will still be used when moving a window whose save-unders has not yet been set or has been invalidated. .IP Some VNC Viewers provide better response than others with this option. On Unix, realvnc viewer gives smoother drags than tightvnc viewer. Response may also be choppy if the server side machine is too slow. .IP Sometimes on very slow modem connections, this actually gives an improvement because no pixel data at all (not even the box animation) is sent during the drag. .PP \fB-ncache_no_moveraise\fR .IP In \fB-ncache\fR mode, do not assume that moving a window will cause the window manager to raise it to the top of the stack. The default is to assume it does, and so at the beginning of any wireframe, etc, window moves the window will be pushed to top in the VNC viewer. .PP \fB-ncache_no_dtchange\fR .IP In \fB-ncache\fR mode, do not try to guess when the desktop (viewport) changes to another one (i.e. another workarea). The default is to try to guess and when detected try to make the transition more smoothly. .PP \fB-ncache_no_rootpixmap\fR .IP In \fB-ncache\fR mode, do not try to snapshot the desktop background to use in guessing or reconstructing window save-unders. .PP \fB-ncache_keep_anims\fR .IP In \fB-ncache\fR mode, do not try to disable window manager animations and other effects (that usually degrade ncache performance or cause painting errors). The default is to try to disable them on KDE (but not GNOME) when VNC clients are connected. .IP For other window managers or desktops that provide animations, effects, compositing, translucency, etc. that interfere with the \fB-ncache\fR method you will have to disable them manually. .PP \fB-ncache_old_wm\fR .IP In \fB-ncache\fR mode, enable some heuristics for old style window managers such as fvwm and twm. .PP \fB-ncache_pad\fR \fIn\fR .IP In \fB-ncache\fR mode, pad each window with n pixels for the caching rectangles. This can be used to try to improve the situation with dropshadows or other compositing (e.g. MacOS X window manager), although it could make things worse. The default is 0 on Unix and 24 on MacOS X. .PP \fB-debug_ncache\fR .IP Turn on debugging and profiling output under \fB-ncache.\fR .PP \fB-wireframe\fR \fI[str],\fR \fB-nowireframe\fR .IP Try to detect window moves or resizes when a mouse button is held down and show a wireframe instead of the full opaque window. This is based completely on heuristics and may not always work: it depends on your window manager and even how you move things around. See \fB-pointer_mode\fR below for discussion of the "bogging down" problem this tries to avoid. Default: \fB-wireframe\fR .IP Shorter aliases: \fB-wf\fR [str] and \fB-nowf\fR .IP The value "str" is optional and, of course, is packed with many tunable parameters for this scheme: .IP Format: shade,linewidth,percent,T+B+L+R,mod,t1+t2+t3+t4 Default: 0xff,2,0,32+8+8+8,all,0.15+0.30+5.0+0.125 .IP If you leave nothing between commas: ",," the default value is used. If you don't specify enough commas, the trailing parameters are set to their defaults. .IP "shade" indicate the "color" for the wireframe, usually a greyscale: 0-255, however for 16 and 32bpp you can specify an rgb.txt X color (e.g. "dodgerblue") or a value > 255 is treated as RGB (e.g. red is 0xff0000). "linewidth" sets the width of the wireframe in pixels. "percent" indicates to not apply the wireframe scheme to windows with area less than this percent of the full screen. .IP "T+B+L+R" indicates four integers for how close in pixels the pointer has to be from the Top, Bottom, Left, or Right edges of the window to consider wireframing. This is a speedup to quickly exclude a window from being wireframed: set them all to zero to not try the speedup (scrolling and selecting text will likely be slower). .IP "mod" specifies if a button down event in the interior of the window with a modifier key (Alt, Shift, etc.) down should indicate a wireframe opportunity. It can be "0" or "none" to skip it, "1" or "all" to apply it to any modifier, or "Shift", "Alt", "Control", "Meta", "Super", or "Hyper" to only apply for that type of modifier key. .IP "t1+t2+t3+t4" specify four floating point times in seconds: t1 is how long to wait for the pointer to move, t2 is how long to wait for the window to start moving or being resized (for some window managers this can be rather long), t3 is how long to keep a wireframe moving before repainting the window. t4 is the minimum time between sending wireframe "animations". If a slow link is detected, these values may be automatically changed to something better for a slow link. .PP \fB-nowireframelocal\fR .IP By default, mouse motion and button presses of a user sitting at the LOCAL display are monitored for wireframing opportunities (so that the changes will be sent efficiently to the VNC clients). Use this option to disable this behavior. .PP \fB-wirecopyrect\fR \fImode,\fR \fB-nowirecopyrect\fR .IP Since the \fB-wireframe\fR mechanism evidently tracks moving windows accurately, a speedup can be obtained by telling the VNC viewers to locally copy the translated window region. This is the VNC CopyRect encoding: the framebuffer update doesn't need to send the actual new image data. .IP Shorter aliases: \fB-wcr\fR [mode] and \fB-nowcr\fR .IP "mode" can be "never" (same as \fB-nowirecopyrect)\fR to never try the copyrect, "top" means only do it if the window was not covered by any other windows, and "always" means to translate the originally unobscured region (this may look odd as the remaining pieces come in, but helps on a slow link). Default: "always" .IP Note: there can be painting errors or slow response when using \fB-scale\fR so you may want to disable CopyRect in this case "\fB-wirecopyrect\fR \fInever\fR" on the command line or by remote-control. Or you can also use the "\fB-scale\fR \fIxxx:nocr\fR" scale option. .PP \fB-debug_wireframe\fR .IP Turn on debugging info printout for the wireframe heuristics. "\fB-dwf\fR" is an alias. Specify multiple times for more output. .PP \fB-scrollcopyrect\fR \fImode,\fR \fB-noscrollcopyrect\fR .IP Like \fB-wirecopyrect,\fR but use heuristics to try to guess if a window has scrolled its contents (either vertically or horizontally). This requires the RECORD X extension to "snoop" on X applications (currently for certain XCopyArea and XConfigureWindow X protocol requests). Examples: Hitting <Return> in a terminal window when the cursor was at the bottom, the text scrolls up one line. Hitting <Down> arrow in a web browser window, the web page scrolls up a small amount. Or scrolling with a scrollbar or mouse wheel. .IP Shorter aliases: \fB-scr\fR [mode] and \fB-noscr\fR .IP This scheme will not always detect scrolls, but when it does there is a nice speedup from using the VNC CopyRect encoding (see \fB-wirecopyrect).\fR The speedup is both in reduced network traffic and reduced X framebuffer polling/copying. On the other hand, it may induce undesired transients (e.g. a terminal cursor being scrolled up when it should not be) or other painting errors (window tearing, bunching-up, etc). These are automatically repaired in a short period of time. If this is unacceptable disable the feature with \fB-noscrollcopyrect.\fR .IP Screen clearing kludges: for testing at least, there are some "magic key sequences" (must be done in less than 1 second) to aid repairing painting errors that may be seen when using this mode: .IP 3 Alt_L's in a row: resend whole screen, 4 Alt_L's in a row: reread and resend whole screen, 3 Super_L's in a row: mark whole screen for polling, 4 Super_L's in a row: reset RECORD context, 5 Super_L's in a row: try to push a black screen .IP note: Alt_L is the Left "Alt" key (a single key) Super_L is the Left "Super" key (Windows flag). Both of these are modifier keys, and so should not generate characters when pressed by themselves. Also, your VNC viewer may have its own refresh hot-key or button. .IP "mode" can be "never" (same as \fB-noscrollcopyrect)\fR to never try the copyrect, "keys" means to try it in response to keystrokes only, "mouse" means to try it in response to mouse events only, "always" means to do both. Default: "always" .IP Note: there can be painting errors or slow response when using \fB-scale\fR so you may want to disable CopyRect in this case "\fB-scrollcopyrect\fR \fInever\fR" on the command line or by remote-control. Or you can also use the "\fB-scale\fR \fIxxx:nocr\fR" scale option. .PP \fB-scr_area\fR \fIn\fR .IP Set the minimum area in pixels for a rectangle to be considered for the \fB-scrollcopyrect\fR detection scheme. This is to avoid wasting the effort on small rectangles that would be quickly updated the normal way. E.g. suppose an app updated the position of its skinny scrollbar first and then shifted the large panel it controlled. We want to be sure to skip the small scrollbar and get the large panel. Default: 60000 .PP \fB-scr_skip\fR \fIlist\fR .IP Skip scroll detection for applications matching the comma separated list of strings in \fIlist\fR. Some applications implement their scrolling in strange ways where the XCopyArea, etc, also applies to invisible portions of the window: if we CopyRect those areas it looks awful during the scroll and there may be painting errors left after the scroll. Soffice.bin is the worst known offender. .IP Use "##" to denote the start of the application class (e.g. "##XTerm") and "++" to denote the start of the application instance name (e.g. "++xterm"). The string your list is matched against is of the form "^^WM_NAME##Class++Instance<same-for-any-subwindows>" The "xlsclients \fB-la"\fR command will provide this info. .IP If a pattern is prefixed with "KEY:" it only applies to Keystroke generated scrolls (e.g. Up arrow). If it is prefixed with "MOUSE:" it only applies to Mouse induced scrolls (e.g. dragging on a scrollbar). Default: ##Soffice.bin,##StarOffice,##OpenOffice .PP \fB-scr_inc\fR \fIlist\fR .IP Opposite of \fB-scr_skip:\fR this list is consulted first and if there is a match the window will be monitored via RECORD for scrolls irrespective of \fB-scr_skip.\fR Use \fB-scr_skip\fR '*' to skip anything that does not match your \fB-scr_inc.\fR Use \fB-scr_inc\fR '*' to include everything. .PP \fB-scr_keys\fR \fIlist\fR .IP For keystroke scroll detection, only apply the RECORD heuristics to the comma separated list of keysyms in \fIlist\fR. You may find the RECORD overhead for every one of your keystrokes disrupts typing too much, but you don't want to turn it off completely with "\fB-scr\fR \fImouse\fR" and \fB-scr_parms\fR does not work or is too confusing. .IP The listed keysyms can be numeric or the keysym names in the <X11/keysymdef.h> header file or from the .IR xev (1) program. Example: "\fB-scr_keys\fR \fIUp,Down,Return\fR". One probably wants to have application specific lists (e.g. for terminals, etc) but that is too icky to think about for now... .IP If \fIlist\fR begins with the "-" character the list is taken as an exclude list: all keysyms except those list will be considered. The special string "builtin" expands to an internal list of keysyms that are likely to cause scrolls. BTW, by default modifier keys, Shift_L, Control_R, etc, are skipped since they almost never induce scrolling by themselves. .PP \fB-scr_term\fR \fIlist\fR .IP Yet another cosmetic kludge. Apply shell/terminal heuristics to applications matching comma separated list (same as for \fB-scr_skip/-scr_inc).\fR For example an annoying transient under scroll detection is if you hit Enter in a terminal shell with full text window, the solid text cursor block will be scrolled up. So for a short time there are two (or more) block cursors on the screen. There are similar scenarios, (e.g. an output line is duplicated). .IP These transients are induced by the approximation of scroll detection (e.g. it detects the scroll, but not the fact that the block cursor was cleared just before the scroll). In nearly all cases these transient errors are repaired when the true X framebuffer is consulted by the normal polling. But they are distracting, so what this option provides is extra "padding" near the bottom of the terminal window: a few extra lines near the bottom will not be scrolled, but rather updated from the actual X framebuffer. This usually reduces the annoying artifacts. Use "none" to disable. Default: "term" .PP \fB-scr_keyrepeat\fR \fIlo-hi\fR .IP If a key is held down (or otherwise repeats rapidly) and this induces a rapid sequence of scrolls (e.g. holding down an Arrow key) the "scrollcopyrect" detection and overhead may not be able to keep up. A time per single scroll estimate is performed and if that estimate predicts a sustainable scrollrate of keys per second between "lo" and "hi" then repeated keys will be DISCARDED to maintain the scrollrate. For example your key autorepeat may be 25 keys/sec, but for a large window or slow link only 8 scrolls per second can be sustained, then roughly 2 out of every 3 repeated keys will be discarded during this period. Default: "4-20" .PP \fB-scr_parms\fR \fIstring\fR .IP Set various parameters for the scrollcopyrect mode. The format is similar to that for \fB-wireframe\fR and packed with lots of parameters: .IP Format: T+B+L+R,t1+t2+t3,s1+s2+s3+s4+s5 Default: 0+64+32+32,0.02+0.10+0.9,0.03+0.06+0.5+0.1+5.0 .IP If you leave nothing between commas: ",," the default value is used. If you don't specify enough commas, the trailing parameters are set to their defaults. .IP "T+B+L+R" indicates four integers for how close in pixels the pointer has to be from the Top, Bottom, Left, or Right edges of the window to consider scrollcopyrect. If \fB-wireframe\fR overlaps it takes precedence. This is a speedup to quickly exclude a window from being watched for scrollcopyrect: set them all to zero to not try the speedup (things like selecting text will likely be slower). .IP "t1+t2+t3" specify three floating point times in seconds that apply to scrollcopyrect detection with *Keystroke* input: t1 is how long to wait after a key is pressed for the first scroll, t2 is how long to keep looking after a Keystroke scroll for more scrolls. t3 is how frequently to try to update surrounding scrollbars outside of the scrolling area (0.0 to disable) .IP "s1+s2+s3+s4+s5" specify five floating point times in seconds that apply to scrollcopyrect detection with *Mouse* input: s1 is how long to wait after a mouse button is pressed for the first scroll, s2 is how long to keep waiting for additional scrolls after the first Mouse scroll was detected. s3 is how frequently to try to update surrounding scrollbars outside of the scrolling area (0.0 to disable). s4 is how long to buffer pointer motion (to try to get fewer, bigger mouse scrolls). s5 is the maximum time to spend just updating the scroll window without updating the rest of the screen. .PP \fB-fixscreen\fR \fIstring\fR .IP Periodically "repair" the screen based on settings in \fIstring\fR. Hopefully you won't need this option, it is intended for cases when the \fB-scrollcopyrect\fR or \fB-wirecopyrect\fR features leave too many painting errors, but it can be used for any scenario. This option periodically performs costly operations and so interactive response may be reduced when it is on. You can use 3 Alt_L's (the Left "Alt" key) taps in a row (as described under \fB-scrollcopyrect)\fR instead to manually request a screen repaint when it is needed. .IP \fIstring\fR is a comma separated list of one or more of the following: "V=t", "C=t", "X=t", and "8=t". In these "t" stands for a time in seconds (it is a floating point even though one should usually use values > 2 to avoid wasting resources). V sets how frequently the entire screen should be sent to viewers (it is like the 3 Alt_L's). C sets how long to wait after a CopyRect to repaint the full screen. X sets how frequently to reread the full X11 framebuffer from the X server and push it out to connected viewers. Use of X should be rare, please report a bug if you find you need it. 8= applies only for \fB-8to24\fR mode: it sets how often the non-default visual regions of the screen (e.g. 8bpp windows) are refreshed. Examples: \fB-fixscreen\fR V=10 \fB-fixscreen\fR C=10 .PP \fB-debug_scroll\fR .IP Turn on debugging info printout for the scroll heuristics. "\fB-ds\fR" is an alias. Specify it multiple times for more output. .PP \fB-noxrecord\fR .IP Disable any use of the RECORD extension. This is currently used by the \fB-scrollcopyrect\fR scheme and to monitor X server grabs. .PP \fB-grab_buster,\fR \fB-nograb_buster\fR .IP Some of the use of the RECORD extension can leave a tiny window for XGrabServer deadlock. This is only if the whole-server grabbing application expects mouse or keyboard input before releasing the grab. It is usually a window manager that does this. x11vnc takes care to avoid the problem, but if caught x11vnc will freeze. Without \fB-grab_buster,\fR the only solution is to go the physical display and give it some input to satisfy the grabbing app. Or manually kill and restart the window manager if that is feasible. With \fB-grab_buster,\fR x11vnc will fork a helper thread and if x11vnc appears to be stuck in a grab after a period of time (20-30 sec) then it will inject some user input: button clicks, Escape, mouse motion, etc to try to break the grab. If you experience a lot of grab deadlock, please report a bug. .PP \fB-debug_grabs\fR .IP Turn on debugging info printout with respect to XGrabServer() deadlock for \fB-scrollcopyrect__mode_.\fR .PP \fB-debug_sel\fR .IP Turn on debugging info printout with respect to PRIMARY, CLIPBOARD, and CUTBUFFER0 selections. .PP \fB-pointer_mode\fR \fIn\fR .IP Various pointer motion update schemes. "\fB-pm\fR" is an alias. The problem is pointer motion can cause rapid changes on the screen: consider the rapid changes when you drag a large window around opaquely. Neither x11vnc's screen polling and vnc compression routines nor the bandwidth to the vncviewers can keep up these rapid screen changes: everything will bog down when dragging or scrolling. So a scheme has to be used to "eat" much of that pointer input before re-polling the screen and sending out framebuffer updates. The mode number \fIn\fR can be 0 to 4 and selects one of the schemes described below. .IP Note that the \fB-wireframe\fR and \fB-scrollcopyrect__mode_s\fR complement \fB-pointer_mode\fR by detecting (and improving) certain periods of "rapid screen change". .IP n=0: does the same as \fB-nodragging.\fR (all screen polling is suspended if a mouse button is pressed.) .IP n=1: was the original scheme used to about Jan 2004: it basically just skips \fB-input_skip\fR keyboard or pointer events before repolling the screen. .IP n=2 is an improved scheme: by watching the current rate of input events it tries to detect if it should try to "eat" additional pointer events before continuing. .IP n=3 is basically a dynamic \fB-nodragging\fR mode: it detects when the mouse motion has paused and then refreshes the display. .IP n=4 attempts to measures network rates and latency, the video card read rate, and how many tiles have been changed on the screen. From this, it aggressively tries to push screen "frames" when it decides it has enough resources to do so. NOT FINISHED. .IP The default n is 2. Note that modes 2, 3, 4 will skip \fB-input_skip\fR keyboard events (but it will not count pointer events). Also note that these modes are not available in \fB-threads\fR mode which has its own pointer event handling mechanism. .IP To try out the different pointer modes to see which one gives the best response for your usage, it is convenient to use the remote control function, for example "x11vnc \fB-R\fR pm:4" or the tcl/tk gui (Tuning -> pointer_mode -> n). .PP \fB-input_skip\fR \fIn\fR .IP For the pointer handling when non-threaded: try to read n user input events before scanning display. n < 0 means to act as though there is always user input. Default: 10 .PP \fB-allinput\fR .IP Have x11vnc read and process all available client input before proceeding. .PP \fB-input_eagerly\fR .IP Similar to \fB-allinput\fR but use the handleEventsEagerly mechanism built into LibVNCServer. .PP \fB-multiptr\fR .IP Enable support for per-client input devices. Each client will get its own cursor and keyboard focus. .PP \fB-speeds\fR \fIrd,bw,lat\fR .IP x11vnc tries to estimate some speed parameters that are used to optimize scheduling (e.g. \fB-pointer_mode\fR 4, \fB-wireframe,\fR \fB-scrollcopyrect)\fR and other things. Use the \fB-speeds\fR option to set these manually. The triple \fIrd,bw,lat\fR corresponds to video h/w read rate in MB/sec, network bandwidth to clients in KB/sec, and network latency to clients in milliseconds, respectively. If a value is left blank, e.g. "-speeds ,100,15", then the internal scheme is used to estimate the empty value(s). .IP Typical PC video cards have read rates of 5-10 MB/sec. If the framebuffer is in main memory instead of video h/w (e.g. SunRay, shadowfb, dummy driver, Xvfb), the read rate may be much faster. "x11perf \fB-getimage500"\fR can be used to get a lower bound (remember to factor in the bytes per pixel). It is up to you to estimate the network bandwidth and latency to clients. For the latency the .IR ping (1) command can be used. .IP For convenience there are some aliases provided, e.g. "\fB-speeds\fR \fImodem\fR". The aliases are: "modem" for 6,4,200; "dsl" for 6,100,50; and "lan" for 6,5000,1 .PP \fB-wmdt\fR \fIstring\fR .IP For some features, e.g. \fB-wireframe\fR and \fB-scrollcopyrect,\fR x11vnc has to work around issues for certain window managers or desktops (currently kde and xfce). By default it tries to guess which one, but it can guess incorrectly. Use this option to indicate which wm/dt. \fIstring\fR can be "gnome", "kde", "cde", "xfce", or "root" (classic X wm). Anything else is interpreted as "root". .PP \fB-debug_pointer\fR .IP Print debugging output for every pointer event. .PP \fB-debug_keyboard\fR .IP Print debugging output for every keyboard event. .PP Same as \fB-dp\fR and \fB-dk,\fR respectively. Use multiple times for more output. .PP \fB-defer\fR \fItime\fR .IP Time in ms to delay sending updates to connected clients (deferUpdateTime) Default: 20 .PP \fB-wait\fR \fItime\fR .IP Time in ms to pause between screen polls. Used to cut down on load. Default: 20 .PP \fB-extra_fbur\fR \fIn\fR .IP Perform extra FrameBufferUpdateRequests checks to try to be in better sync with the client's requests. What this does is perform extra polls of the client socket at critical times (before '-defer' and '-wait' calls.) The default is n=1. Set to a larger number to insert more checks or set to n=0 to disable. A downside of these extra calls is that more mouse input may be processed than desired. .PP \fB-wait_ui\fR \fIfactor\fR .IP Factor by which to cut the \fB-wait\fR time if there has been recent user input (pointer or keyboard). Improves response, but increases the load whenever you are moving the mouse or typing. Default: 2.00 .PP \fB-setdefer\fR \fIn\fR .IP When the \fB-wait_ui\fR mechanism cuts down the wait time ms, set the defer time to the same ms value. n=1 to enable, 0 to disable, and -1 to set defer to 0 (no delay). Similarly, 2 and -2 indicate 'urgent_update' mode should be used to push the updates even sooner. Default: 1 .PP \fB-nowait_bog\fR .IP Do not detect if the screen polling is "bogging down" and sleep more. Some activities with no user input can slow things down a lot: consider a large terminal window with a long build running in it continuously streaming text output. By default x11vnc will try to detect this (3 screen polls in a row each longer than 0.25 sec with no user input), and sleep up to 1.5 secs to let things "catch up". Use this option to disable that detection. .PP \fB-slow_fb\fR \fItime\fR .IP Floating point time in seconds to delay all screen polling. For special purpose usage where a low frame rate is acceptable and desirable, but you want the user input processed at the normal rate so you cannot use \fB-wait.\fR .PP \fB-xrefresh\fR \fItime\fR .IP Floating point time in seconds to indicate how often to do the equivalent of .IR xrefresh (1) to force all windows (in the viewable area if \fB-id,\fR \fB-sid,\fR or \fB-clip\fR is used) to repaint themselves. Use this only if applications misbehave by not repainting themselves properly. See also \fB-noxdamage.\fR .PP \fB-nap,\fR \fB-nonap\fR .IP Monitor activity and if it is low take longer naps between screen polls to really cut down load when idle. Default: take naps .PP \fB-sb\fR \fItime\fR .IP Time in seconds after NO activity (e.g. screen blank) to really throttle down the screen polls (i.e. sleep for about 1.5 secs). Use 0 to disable. Default: 60 Set the env. var. X11VNC_SB_FACTOR to scale it. .PP \fB-readtimeout\fR \fIn\fR .IP Set LibVNCServer rfbMaxClientWait to n seconds. On slow links that take a long time to paint the first screen LibVNCServer may hit the timeout and drop the connection. Default: 20 seconds. .PP \fB-ping\fR \fIn\fR .IP Send a 1x1 framebuffer update to all clients every n seconds (e.g. to try to keep a network connection alive) .PP \fB-nofbpm,\fR \fB-fbpm\fR .IP If the system supports the FBPM (Frame Buffer Power Management) extension (i.e. some Sun systems), then prevent the video h/w from going into a reduced power state when VNC clients are connected. .IP FBPM capable video h/w save energy when the workstation is idle by going into low power states (similar to DPMS for monitors). This interferes with x11vnc's polling of the framebuffer data. .IP "\fB-nofbpm\fR" means prevent FBPM low power states whenever VNC clients are connected, while "\fB-fbpm\fR" means to not monitor the FBPM state at all. See the .IR xset (1) manpage for details. \fB-nofbpm\fR is basically the same as running "xset fbpm force on" periodically. Default: \fB-fbpm\fR .PP \fB-nodpms,\fR \fB-dpms\fR .IP If the system supports the DPMS (Display Power Management Signaling) extension, then prevent the monitor from going into a reduced power state when VNC clients are connected. .IP DPMS reduced power monitor states are a good thing and you normally want the power down to take place (usually x11vnc has no problem exporting the display in this state). You probably only want to use "\fB-nodpms\fR" to work around problems with Screen Savers kicking on in DPMS low power states. There is known problem with kdesktop_lock on KDE where the screen saver keeps kicking in every time user input stops for a second or two. Specifying "\fB-nodpms\fR" works around it. .IP "\fB-nodpms\fR" means prevent DPMS low power states whenever VNC clients are connected, while "\fB-dpms\fR" means to not monitor the DPMS state at all. See the .IR xset (1) manpage for details. \fB-nodpms\fR is basically the same as running "xset dpms force on" periodically. Default: \fB-dpms\fR .PP \fB-forcedpms\fR .IP If the system supports the DPMS (Display Power Management Signaling) extension, then try to keep the monitor in a powered off state. This is to prevent nosey people at the physical display from viewing what is on the screen. Be sure to lock the screen before disconnecting. .IP This method is far from bullet proof, e.g. suppose someone attaches a non-DPMS monitor, or loads the machine so that there is a gap of time before x11vnc restores the powered off state? On many machines if he floods it with keyboard and mouse input he can see flashes of what is on the screen before the DPMS off state is reestablished. For this to work securely there would need to be support in the X server to do this exactly rather than approximately with DPMS. .PP \fB-clientdpms\fR .IP As \fB-forcedpms\fR but only when VNC clients are connected. .PP \fB-noserverdpms\fR .IP The UltraVNC ServerInput extension is supported. This allows the VNC viewer to click a button that will cause the server (x11vnc) to try to disable keyboard and mouse input at the physical display and put the monitor in dpms powered off state. Use this option to skip powering off the monitor. .PP \fB-noultraext\fR .IP Disable the following UltraVNC extensions: SingleWindow and ServerInput. The others managed by LibVNCServer (textchat, 1/n scaling, rfbEncodingUltra) are not. .PP \fB-chatwindow\fR .IP Place a local UltraVNC chat window on the X11 display that x11vnc is polling. That way the person on the VNC viewer-side can chat with the person at the physical X11 console. (e.g. helpdesk w/o telephone) .IP For this to work the SSVNC package (version 1.0.21 or later) MUST BE installed on the system where x11vnc runs and the 'ssvnc' command must be available in $PATH. The ssvncviewer is used as a chat window helper. See http://www.karlrunge.com/x11vnc/ssvnc.html .IP This option implies '-rfbversion 3.6' so as to trick UltraVNC viewers, otherwise they assume chat is not available. To specify a different rfbversion, place it after the \fB-chatwindow\fR option on the cmdline. .IP See also the remote control 'chaton' and 'chatoff' actions. These can also be set from the tkx11vnc GUI. .PP \fB-noxdamage\fR .IP Do not use the X DAMAGE extension to detect framebuffer changes even if it is available. Use \fB-xdamage\fR if your default is to have it off. .IP x11vnc's use of the DAMAGE extension: 1) significantly reduces the load when the screen is not changing much, and 2) detects changed areas (small ones by default) more quickly. .IP Currently the DAMAGE extension is overly conservative and often reports large areas (e.g. a whole terminal or browser window) as damaged even though the actual changed region is much smaller (sometimes just a few pixels). So heuristics were introduced to skip large areas and use the damage rectangles only as "hints" for the traditional scanline polling. The following tuning parameters are introduced to adjust this behavior: .PP \fB-xd_area\fR \fIA\fR .IP Set the largest DAMAGE rectangle area \fIA\fR (in pixels: width * height) to trust as truly damaged: the rectangle will be copied from the framebuffer (slow) no matter what. Set to zero to trust *all* rectangles. Default: 20000 .PP \fB-xd_mem\fR \fIf\fR .IP Set how long DAMAGE rectangles should be "remembered", \fIf\fR is a floating point number and is in units of the scanline repeat cycle time (32 iterations). The default (1.0) should give no painting problems. Increase it if there are problems or decrease it to live on the edge (perhaps useful on a slow machine). .PP \fB-sigpipe\fR \fIstring\fR .IP Broken pipe (SIGPIPE) handling. \fIstring\fR can be "ignore" or "exit". For "ignore" LibVNCServer will handle the abrupt loss of a client and continue, for "exit" x11vnc will cleanup and exit at the 1st broken connection. .IP This option is not really needed since LibVNCServer is doing the correct thing now for quite some time. However, for convenience you can use it to ignore other signals, e.g. "\fB-sigpipe\fR \fIignore:HUP,INT,TERM\fR" in case that would be useful for some sort of application. You can also put "exit:.." in the list to have x11vnc cleanup on the listed signals. "\fB-sig\fR" is an alias for this option if you don't like the 'pipe'. Example: \fB-sig\fR ignore:INT,TERM,exit:USR1 .PP \fB-threads,\fR \fB-nothreads\fR .IP Whether or not to use the threaded LibVNCServer algorithm [rfbRunEventLoop] if libpthread is available. In this mode new threads (one for input and one for output) are created to handle each new client. Default: \fB-nothreads.\fR .IP Thread stability is much improved in version 0.9.8. .IP Multiple clients in threaded mode should be stable for the ZRLE encoding on all platforms. The Tight and Zlib encodings are currently only stable on Linux for multiple clients. Compile with \fB-DTLS=__thread\fR if your OS and compiler and linker support it. .IP For resizes (randr, etc.) set this env. var. to the number of milliseconds to sleep: X11VNC_THREADS_NEW_FB_SLEEP at various places in the do_new_fb() action. This is to let various activities settle. Default is about 500ms. .IP Multiple clients in threaded mode could yield better performance for 'class-room' broadcasting usage; also in \fB-appshare\fR broadcast mode. See also the \fB-reflect\fR option. .PP \fB-fs\fR \fIf\fR .IP If the fraction of changed tiles in a poll is greater than f, the whole screen is updated. Default: 0.75 .PP \fB-gaps\fR \fIn\fR .IP Heuristic to fill in gaps in rows or cols of n or less tiles. Used to improve text paging. Default: 4 .PP \fB-grow\fR \fIn\fR .IP Heuristic to grow islands of changed tiles n or wider by checking the tile near the boundary. Default: 3 .PP \fB-fuzz\fR \fIn\fR .IP Tolerance in pixels to mark a tiles edges as changed. Default: 2 .PP \fB-debug_tiles\fR .IP Print debugging output for tiles, fb updates, etc. .PP \fB-snapfb\fR .IP Instead of polling the X display framebuffer (fb) for changes, periodically copy all of X display fb into main memory and examine that copy for changes. (This setting also applies for non-X \fB-rawfb\fR modes). Under some circumstances this will improve interactive response, or at least make things look smoother, but in others (most!) it will make the response worse. If the video h/w fb is such that reading small tiles is very slow this mode could help. To keep the "framerate" up the screen size x bpp cannot be too large. Note that this mode is very wasteful of memory I/O resources (it makes full screen copies even if nothing changes). It may be of use in video capture-like applications, webcams, or where window tearing is a problem. .PP \fB-rawfb\fR \fIstring\fR .IP Instead of polling X, poll the memory object specified in \fIstring\fR. .IP For file polling, to memory map .IR mmap (2) a file use: "map:/path/to/a/file@WxHxB", with framebuffer Width, Height, and Bits per pixel. "mmap:..." is the same. .IP If there is trouble with mmap, use "file:/..." for slower .IR lseek (2) based reading. .IP Use "snap:..." to imply \fB-snapfb\fR mode and the "file:" access (this is for unseekable devices that only provide the fb all at once, e.g. a video camera provides the whole frame). .IP For shared memory segments string is of the form: "shm:N@WxHxB" which specifies a shmid N and with WxHxB as above. See .IR shmat (1) and .IR ipcs (1) .IP If you do not supply a type "map" is assumed if the file exists (see the next paragraphs for some exceptions to this.) .IP If string is "setup:cmd", then the command "cmd" is run and the first line from it is read and used as \fIstring\fR. This allows initializing the device, determining WxHxB, etc. These are often done as root so take care. .IP If the string begins with "video", see the VIDEO4LINUX discussion below where the device may be queried for (and possibly set) the framebuffer parameters. .IP If the string begins with "console", "/dev/fb", "fb", or "vt", see the LINUX CONSOLE discussion below where the framebuffer device is opened and keystrokes (and possibly mouse events) are inserted into the console. .IP If the string begins with "vnc", see the VNC HOST discussion below where the framebuffer is taken as that of another remote VNC server. .IP Optional suffixes are ":R/G/B" and "+O" to specify red, green, and blue masks (in hex) and an offset into the memory object. If the masks are not provided x11vnc guesses them based on the bpp (if the colors look wrong, you need to provide the masks.) .IP Another optional suffix is the Bytes Per Line which in some cases is not WxB/8. Specify it as WxHxB-BPL e.g. 800x600x16-2048. This could be a normal width 1024 at 16bpp fb, but only width 800 shows up. .IP So the full format is: mode:file@WxHxB:R/G/B+O-BPL .IP Examples: .IP \fB-rawfb\fR shm:210337933@800x600x32:ff/ff00/ff0000 .IP \fB-rawfb\fR map:/dev/fb0@1024x768x32 .IP \fB-rawfb\fR map:/tmp/Xvfb_screen0@640x480x8+3232 .IP \fB-rawfb\fR file:/tmp/my.pnm@250x200x24+37 .IP \fB-rawfb\fR file:/dev/urandom@128x128x8 \fB-rawfb\fR snap:/dev/video0@320x240x24 \fB-24to32\fR \fB-rawfb\fR video0 \fB-rawfb\fR video \fB-pipeinput\fR VID \fB-rawfb\fR console \fB-rawfb\fR vt2 \fB-rawfb\fR vnc:somehost:0 .IP (see .IR ipcs (1) and .IR fbset (1) for the first two examples) .IP In general all user input is discarded by default (see the \fB-pipeinput\fR option for how to use a helper program to insert). Most of the X11 (screen, keyboard, mouse) options do not make sense and many will cause this mode to crash, so please think twice before setting or changing them in a running x11vnc. .IP If you DO NOT want x11vnc to close the X DISPLAY in rawfb mode, prepend a "+" e.g. +file:/dev/fb0... Keeping the display open enables the default remote-control channel, which could be useful. Alternatively, if you specify \fB-noviewonly,\fR then the mouse and keyboard input are STILL sent to the X display, this usage should be very rare, i.e. doing something strange with /dev/fb0. .IP If the device is not "seekable" (e.g. webcam) try reading it all at once in full snaps via the "snap:" mode (note: this is a resource hog). If you are using file: or map: AND the device needs to be reopened for *every* snapfb snapshot, set the environment variable: SNAPFB_RAWFB_RESET=1 as well. .IP If you want x11vnc to dynamically transform a 24bpp rawfb to 32bpp (note that this will be slower) also supply the \fB-24to32\fR option. This would be useful for, say, a video camera that delivers the pixel data as 24bpp packed RGB. This is the default under "video" mode if the bpp is 24. .IP Normally the bits per pixel, B, is 8, 16, or 32 (or rarely 24), however there is also some support for B < 8 (e.g. old graphics displays 4 bpp or 1 bpp). In this case you certainly must supply the masks as well: WxHxB:R/G/B. The pixels will be padded out to 8 bpp using depth 8 truecolor. The scheme currently does not work with snap fb (ask if interested.) B=1 monochrome example: file:/dev/urandom@128x128x1:1/1/1 Some other like this are 128x128x2:3/3/3 128x128x4:7/7/7 .IP For B < 8 framebuffers you can also set the env. var RAWFB_CGA=1 to try a CGA mapping for B=4 (e.g. linux vga16fb driver.) Note with low bpp and/or resolution VGA and VGA16 modes on the Linux console one's attempt to export them via x11vnc can often be thwarted due to special color palettes, pixel packings, and even video painting buffering. OTOH, often experimenting with the RGB masks can yield something recognizable. .IP VIDEO4LINUX: on Linux some attempt is made to handle video devices (webcams or TV tuners) automatically. The idea is the WxHxB will be extracted from the device itself. So if you do not supply "@WxHxB... parameters x11vnc will try to determine them. It first tries the v4l API if that support has been compiled in. Otherwise it will run the v4l- .IR info (1) external program if it is available. .IP The simplest examples are "\fB-rawfb\fR \fIvideo\fR" and "-rawfb video1" which imply the device file /dev/video and /dev/video1, respectively. You can also supply the /dev if you like, e.g. "\fB-rawfb\fR \fI/dev/video0\fR" .IP Since the video capture device framebuffer usually changes continuously (e.g. brightness fluctuations), you may want to use the \fB-wait,\fR \fB-slow_fb,\fR or \fB-defer\fR options to lower the "framerate" to cut down on network VNC traffic. .IP A more sophisticated video device scheme allows initializing the device's settings using: .IP \fB-rawfb\fR video:<settings> .IP The prefix could also be, as above, e.g. "video1:" to specify the device file. The v4l API must be available for this to work. Otherwise, you will need to try to initialize the device with an external program, e.g. xawtv, spcaview, and hope they persist when x11vnc re-opens the device. .IP <settings> is a comma separated list of key=value pairs. The device's brightness, color, contrast, and hue can be set to percentages, e.g. br=80,co=50,cn=44,hu=60. .IP The device filename can be set too if needed (if it does not start with "video"), e.g. fn=/dev/qcam. .IP The width, height and bpp of the framebuffer can be set via, e.g., w=160,h=120,bpp=16. .IP Related to the bpp above, the pixel format can be set via the fmt=XXX, where XXX can be one of: GREY, HI240, RGB555, RGB565, RGB24, and RGB32 (with bpp 8, 8, 16, 16, 24, and 32 respectively). See http://www.linuxtv.org for more info (V4L api). .IP For TV/rf tuner cards one can set the tuning mode via tun=XXX where XXX can be one of PAL, NTSC, SECAM, or AUTO. .IP One can switch the input channel by the inp=XXX setting, where XXX is the name of the input channel (Television, Composite1, S-Video, etc). Use the name that is in the information about the device that is printed at startup. .IP For input channels with tuners (e.g. Television) one can change which station is selected by the sta=XXX setting. XXX is the station number. Currently only the ntsc-cable-us (US cable) channels are built into x11vnc. See the \fB-freqtab\fR option below to supply one from xawtv. If XXX is greater than 500, then it is interpreted as a raw frequency in KHz. .IP Example: .IP \fB-rawfb\fR video:br=80,w=320,h=240,fmt=RGB32,tun=NTSC,sta=47 .IP one might need to add inp=Television too for the input channel to be TV if the card doesn't come up by default in that one. .IP Note that not all video capture devices will support all of the above settings. .IP See the \fB-pipeinput\fR VID option below for a way to control the settings through the VNC Viewer via keystrokes. As a shortcut, if the string begins "Video.." instead of "video.." then \fB-pipeinput\fR VID is implied. .IP As above, if you specify a "@WxHxB..." after the <settings> string they are used verbatim: the device is not queried for the current values. Otherwise the device will be queried. .IP LINUX CONSOLE: The following describes some ways to view and possibly interact with the Linux text/graphics console (i.e. not X11 XFree86/Xorg) .IP Note: If the LibVNCServer LinuxVNC program is on your system you may want to use that instead of the following method because it will be faster and more accurate for the Linux text console and includes mouse support. There is, however, the basic LinuxVNC functionality in x11vnc if you replace "console" with "vt" in the examples below. .IP If the rawfb string begins with "console" the framebuffer device /dev/fb0 is opened and /dev/tty0 is opened too. The latter is used to inject keystrokes (not all are supported, but the basic ones are). You will need to be root to inject keystrokes, but not necessarily to open /dev/fb0. /dev/tty0 refers to the active VT, to indicate one explicitly, use, e.g., "console2" for /dev/tty2, etc. by indicating the specific VT number. .IP For the Linux framebuffer device, /dev/fb0, (fb1, etc) to be enabled the appropriate kernel drivers must be loaded. E.g. vesafb or vga16fb and also by setting the boot parameter vga=0x301 (or 0x314, 0x317, etc.) (The vga=... method is the preferred way; set your machines up that way.) Otherwise there will be a \(aqNo such device\(aq error. You can also load a Linux framebuffer driver specific to your make of video card for more functionality. Once the machine is booted one can often 'modprobe' the fb driver as root to obtain a framebuffer device. .IP If you cannot get /dev/fb0 working on Linux, try using the LinuxVNC emulation mode by "\fB-rawfb\fR \fIvtN\fR" where N = 1, ... 6 is the Linux Virtual Terminal (aka virtual console) you wish to view, e.g. "\fB-rawfb\fR \fIvt2\fR". Unlike /dev/fb mode, it need not be the active Virtual Terminal. Note that this mode can only show text and not graphics. x11vnc polls the text in /dev/vcsaN .IP Set the env. var. RAWFB_VCSA_BW=1 to disable colors in the "vtN" mode (i.e. black and white only.) If you do not prefer the default 16bpp set RAWFB_VCSA_BPP to 8 or 32. If you need to tweak the rawfb parameters by using the 'console_guess' string printed at startup, be sure to indicate the snap: method. .IP uinput: If the Linux version appears to be 2.6 or later and the "uinput" module appears to be present (modprobe uinput), then the uinput method will be used instead of /dev/ttyN. uinput allows insertion of BOTH keystrokes and mouse input and so it preferred when accessing graphical (e.g. QT-embedded) linux console apps. It also provides more accurate keystroke insertion. See \fB-pipeinput\fR UINPUT below for more information on this mode; you will have to use \fB-pipeinput\fR if you want to tweak any UINPUT parameters. You may also want to also use the \fB-nodragging\fR and \fB-cursor\fR none options. Use "console0", etc or \fB-pipeinput\fR CONSOLE to force the /dev/ttyN method. .IP Note you can change the Linux VT remotely using the .IR chvt (1) command to make the one you want be the active one (e.g. 'chvt 3'). Sometimes switching out and back corrects the framebuffer's graphics state. For the "\fB-rawfb\fR \fIvtN\fR" mode there is no need to switch the VT's. .IP To skip input injecting entirely use "consolex" or "vtx". .IP The string "/dev/fb0" (1, etc.) can be used instead of "console". This can be used to specify a different framebuffer device, e.g. /dev/fb1. As a shortcut the "/dev/" can be dropped. If the name is something nonstandard, use "console:/dev/foofb" .IP If you do not want x11vnc to guess the framebuffer's WxHxB and masks automatically (sometimes the kernel gives incorrect information), specify them with a @WxHxB (and optional :R/G/B masks) at the end of the string. .IP Examples: \fB-rawfb\fR console \fB-rawfb\fR /dev/fb0 (same) \fB-rawfb\fR console3 (force /dev/tty3) \fB-rawfb\fR consolex (no keystrokes or mouse) \fB-rawfb\fR console:/dev/nonstd \fB-rawfb\fR console \fB-pipeinput\fR UINPUT:accel=4.0 \fB-rawfb\fR vt3 (/dev/tty3 w/o /dev/fb0) .IP VNC HOST: if the \fB-rawfb\fR string is of the form "vnc:host:N" then the VNC display "N" on the remote VNC server "host" is connected to (i.e. x11vnc acts as a VNC client itself) and that framebuffer is exported. .IP This mode is really only of use if you are trying to improve performance in the case of many (e.g. > 10) simultaneous VNC viewers, and you try a divide and conquer scheme to reduce bandwidth and improve responsiveness. (However, another user found this mode useful to export a demo display through a slow link: then multiple demo viewers connected to the reflecting x11vnc on the fast side of the link, and so avoided all of the demo viewers going through the slow link.) .IP For example, if there will be 64 simultaneous VNC viewers this can lead to a lot of redundant VNC traffic to and from the server host:N, extra CPU usage, and all viewers response can be reduced by having to wait for writes to the slowest client to finish. However, if you set up 8 reflectors/repeaters started with option \fB-rawfb\fR vnc:host:N, then there are only 8 connections to host:N. Each repeater then handles 8 vnc viewer connections thereby spreading the load around. In classroom broadcast usage, try to put the repeaters on different switches. This mode is the same as \fB-reflect\fR host:N. Replace "host:N" by "listen" or "listen:port" for a reverse connection. .IP Overall performance will not be as good as a single direct connection because, among other things, there is an additional level of framebuffer polling and pointer motion can still induce many changes per second that must be propagated. Tip: if the remote VNC is x11vnc doing wireframing, or an X display that does wireframing that gives much better response than opaque window dragging. Consider the \fB-nodragging\fR option if the problem is severe. .IP The env. var. X11VNC_REFLECT_PASSWORD can be set to the password needed to log into the vnc host server, or to "file:path_to_file" to indicate a file containing the password as its first line. .IP To set the pixel format that x11vnc requests as a VNC CLIENT set the env. vars: X11VNC_REFLECT_bitsPerSample X11VNC_REFLECT_samplesPerPixel, and X11VNC_REFLECT_bytesPerPixel; the defaults are 8, 3, 4. 2, 3, 1 would give a low color mode. See the function rfbGetClient() in libvncclient for more info. .IP The VNC HOST mode implies \fB-shared.\fR Use \fB-noshared\fR as a subsequent cmdline option to disable sharing. .PP \fB-freqtab\fR \fIfile\fR .IP For use with "\fB-rawfb\fR \fIvideo\fR" for TV tuner devices to specify station frequencies. Instead of using the built in ntsc-cable-us mapping of station number to frequency, use the data in file. For stations that are not numeric, e.g. SE20, they are placed above the highest numbered station in the order they are found. Example: "\fB-freqtab\fR \fI/usr/X11R6/share/xawtv/europe-west.list\fR" You can make your own freqtab by copying the xawtv format. .PP \fB-pipeinput\fR \fIcmd\fR .IP This option lets you supply an external command in \fIcmd\fR that x11vnc will pipe all of the user input events to in a simple format. In \fB-pipeinput\fR mode by default x11vnc will not process any of the user input events. If you prefix \fIcmd\fR with "tee:" it will both send them to the pipe command and process them. For a description of the format run "-pipeinput tee:/bin/cat". Another prefix is "reopen" which means to reopen pipe if it exits. Separate multiple prefixes with commas. .IP In combination with \fB-rawfb\fR one might be able to do amusing things (e.g. control non-X devices). To facilitate this, if \fB-rawfb\fR is in effect then the value is stored in X11VNC_RAWFB_STR for the pipe command to use if it wants. Do 'env | grep X11VNC' for more. .IP Built-in pipeinput modes (no external program required): .IP If cmd is "VID" and you are using the \fB-rawfb\fR for a video capture device, then an internal list of keyboard mappings is used to set parameters of the video. The mappings are: .IP "B" and "b" adjust the brightness up and down. "H" and "h" adjust the hue. "C" and "c" adjust the colour. "N" and "n" adjust the contrast. "S" and "s" adjust the size of the capture screen. "I" and "i" cycle through input channels. Up and Down arrows adjust the station (if a tuner) F1, F2, ..., F6 will switch the video capture pixel format to HI240, RGB565, RGB24, RGB32, RGB555, and GREY respectively. See \fB-rawfb\fR video for details. .IP If cmd is "CONSOLE" or "CONSOLEn" where n is a Linux console number, then the linux console keystroke insertion to /dev/ttyN (see \fB-rawfb\fR console) is performed. .IP If cmd begins with "UINPUT" then the Linux uinput module is used to insert both keystroke and mouse events to the Linux console (see \fB-rawfb\fR above). This usually is the /dev/input/uinput device file (you may need to create it with "mknod /dev/input/uinput c 10 223" and insert the module with "modprobe uinput". .IP The UINPUT mode currently only does US keyboards (a scan code option may be added), and not all keysyms are supported. But it is probably more accurate than the "CONSOLE" method. .IP You may want to use the options \fB-cursor\fR none and \fB-nodragging\fR in this mode. .IP Additional tuning options may be supplied via: UINPUT:opt1,opt2,... (a comma separated list). If an option begins with "/" it is taken as the uinput device file. .IP Which uinput is injected can be controlled by an option string made of the characters "K", "M", and "B" (see the \fB-input\fR option), e.g. "KM" allows keystroke and motion but not button clicks. .IP A UINPUT option of the form: accel=f, or accel=fx+fy sets the mouse motion "acceleration". This is used to correct raw mouse relative motion into how much the application cursor moves (x11vnc has no control over, or knowledge of how the windowing application interprets the raw mouse motions). Typically the acceleration for an X display is 2 (see xset "m" option). "f" is a floating point number, e.g. 3.0. Use "fx+fy" if you need to supply different corrections for x and y. .IP Note: the default acceleration is 2.0 since it seems both X and qt-embedded often (but not always) use this value. .IP Even with a correct accel setting the mouse position will get out of sync (probably due to a mouse "threshold" setting where the acceleration doe not apply, set .IR xset (1) ). The option reset=N sets the number of ms (default 150) after which the cursor is attempted to be reset (by forcing the mouse to (0, 0) via small increments and then back out to (x, y) in 1 jump), This correction seems to be needed but can cause jerkiness or unexpected behavior with menus, etc. Use reset=0 to disable. .IP If you set the env. var X11VNC_UINPUT_THRESHOLDS then the thresh=n mode will be enabled. It is currently not working well. If |dx| <= thresh and |dy| < thresh no acceleration is applied. Use "thresh=+n" |dx| + |dy| < thresh to be used instead (X11?) .IP Example: \fB-pipeinput\fR UINPUT:accel=4.0 \fB-cursor\fR none .IP If the uinput device has an absolute pointer (as opposed to a normal mouse that is a relative pointer) you can specify the option "abs". Note that a touchpad on a laptop is an absolute device to some degree. This (usually) avoids all the problems with mouse acceleration. If x11vnc has trouble deducing the size of the device, use "abs=WxH". Furthermore, if the device is a touchscreen (assumed to have an absolute pointer) use "touch" or "touch=WxH". For touchscreens, when a mouse button is pressed, a pressure increase is injected, and when the button is released a pressure of zero is injected. .IP If touch has been set, use "touch_always=1" to indicate whenever the mouse moves with no button pressed, a touch event of zero pressure should be sent anyway. Also use "btn_touch=1" to indicate a BTN_TOUCH keystroke press or release should be sent instead of a pressure change. Set "dragskip=n" to skip n dragged mouse touches (with pressure applied) before injecting one. To indicate the pressure that should be sent when there is a button click for a touchscreen device, specify pressure=n, e.g. n=5. The default is n=1. .IP If a touch screen is being used ("touch" above) and it is having its input processed by tslib, you can specify the tslib calibration file via tslib_cal=<file>. For example, tslib_cal=/etc/pointercal. To get accurate or even usable positioning this is required when tslib is in use. .IP The Linux uinput mechanism can be bypassed and one can write input events DIRECTLY to the devices instead. To do this, specify one or more of the following for the input classes: direct_rel=<device> direct_abs=<device> direct_btn=<device> or direct_key=<device>. The <device> file is usually something like /dev/input/event1 but you can specify any device file or pipe. You must specify each one of the above classes even if they correspond to the same device file (rel/abs and btn are often the same.) Look at the file /proc/bus/input/devices to get an idea what is available and the device filenames. Note: The /dev/input/mouse* devices do not seem to work, use the corresponding /dev/input/event* file instead. Any input class not directly specified as above will be handled via the uinput mechanism. To disable creating a uinput device (and thereby discarding unhandled input), specify "nouinput". .IP Examples: .IP \fB-pipeinput\fR UINPUT:direct_abs=/dev/input/event1 .IP this was used on a qtmoko Neo freerunner (armel): .IP \fB-pipeinput\fR UINPUT:touch,tslib_cal=/etc/pointercal, direct_abs=/dev/input/event1,nouinput,dragskip=4 .IP (where the long line has been split into two.) .IP You can set the env. var X11VNC_UINPUT_DEBUG=1 or higher to get debugging output for UINPUT mode. .PP \fB-macnodim\fR .IP For the native MacOSX server, disable dimming. .PP \fB-macnosleep\fR .IP For the native MacOSX server, disable display sleep. .PP \fB-macnosaver\fR .IP For the native MacOSX server, disable screensaver. .PP \fB-macnowait\fR .IP For the native MacOSX server, do not wait for the user to switch back to his display. .PP \fB-macwheel\fR \fIn\fR .IP For the native MacOSX server, set the mouse wheel speed to n (default 5). .PP \fB-macnoswap\fR .IP For the native MacOSX server, do not swap mouse buttons 2 and 3. .PP \fB-macnoresize\fR .IP For the native MacOSX server, do not resize or reset the framebuffer even if it is detected that the screen resolution or depth has changed. .PP \fB-maciconanim\fR \fIn\fR .IP For the native MacOSX server, set n to the number of milliseconds that the window iconify/deiconify animation takes. In \fB-ncache\fR mode this value will be used to skip the animation if possible.

One can force not using any deprecated interfaces at compile time by setting \fB-DX11VNC_MACOSX_NO_DEPRECATED=1\fR in CPPFLAGS. Or to turn them off one by one: \fB-DX11VNC_MACOSX_NO_DEPRECATED_LOCALEVENTS=1,\fR \fB-DX11VNC_MACOSX_NO_DEPRECATED_POSTEVENTS=1\fR or \fB-DX11VNC_MACOSX_NO_DEPRECATED_FRAMEBUFFER=1\fR At run time, for testing and workarounds, one can disable them by using: \fB-env\fR X11VNC_MACOSX_NO_DEPRECATED=1 \fB-env\fR X11VNC_MACOSX_NO_DEPRECATED_LOCALEVENTS=1 \fB-env\fR X11VNC_MACOSX_NO_DEPRECATED_POSTEVENTS=1 or \fB-env\fR X11VNC_MACOSX_NO_DEPRECATED_FRAMEBUFFER=1 Note: When doing either of these for the mouse input not everything works currently, e.g. double clicks and wireframing. Also, screen resolution and pixel depth changes will not be automatically detected unless the deprecated framebuffer interfaces are allowed. .IP Conversely, if you are compiling on an older machine that does not have some of the newer interfaces, you may need to specify \fB-DX11VNC_MACOSX_NO_CGEVENTCREATESCROLLWHEELEVENT\fR \fB-DX11VNC_MACOSX_NO_CGEVENTCREATEMOUSEEVENT\fR or \fB-DX11VNC_MACOSX_NO_CGEVENTCREATEKEYBOARDEVENT.\fR Use \fB-DX11VNC_MACOSX_USE_GETMAINDEVICE\fR to regain the very old QuickDraw GetMainDevice() interface (rare...) .PP \fB-gui\fR \fI[gui-opts]\fR .IP Start up a simple tcl/tk gui based on the remote control options \fB-remote/-query\fR described below. Requires the "wish" program to be installed on the machine. "gui-opts" is not required: the default is to start up both the full gui and x11vnc with the gui showing up on the X display in the environment variable DISPLAY. .IP "gui-opts" can be a comma separated list of items. Currently there are these types of items: 1) a gui mode, a 2) gui "simplicity", 3) the X display the gui should display on, 4) a "tray" or "icon" mode, and 5) a gui geometry. .IP 1) The gui mode can be "start", "conn", or "wait" "start" is the default mode above and is not required. "conn" means do not automatically start up x11vnc, but instead just try to connect to an existing x11vnc process. "wait" means just start the gui and nothing else (you will later instruct the gui to start x11vnc or connect to an existing one.) .IP 2) The gui simplicity is off by default (a power-user gui with all options is presented) To start with something less daunting supply the string "simple" ("ez" is an alias for this). Once the gui is started you can toggle between the two with "Misc -> simple_gui". .IP 3) Note the possible confusion regarding the potentially two different X displays: x11vnc polls one, but you may want the gui to appear on another. For example, if you ssh in and x11vnc is not running yet you may want the gui to come back to you via your ssh redirected X display (e.g. localhost:10). .IP If you do not specify a gui X display in "gui-opts" then the DISPLAY environment variable and \fB-display\fR option are tried (in that order). Regarding the x11vnc X display the gui will try to communication with, it first tries \fB-display\fR and then DISPLAY. For example, "x11vnc \fB-display\fR :0 \fB-gui\fR otherhost:0", will remote control an x11vnc polling :0 and display the gui on otherhost:0 The "tray/icon" mode below reverses this preference, preferring to display on the x11vnc display. .IP 4) When "tray" or "icon" is specified, the gui presents itself as a small icon with behavior typical of a "system tray" or "dock applet". The color of the icon indicates status (connected clients) and there is also a balloon status. Clicking on the icon gives a menu from which properties, etc, can be set and the full gui is available under "Advanced". To be fully functional, the gui mode should be "start" (the default). .IP Note that tray or icon mode will imply the \fB-forever\fR x11vnc option (if the x11vnc server is started along with the gui) unless \fB-connect\fR or \fB-connect_or_exit\fR has been specified. So x11vnc (and the tray/icon gui) will wait for more connections after the first client disconnects. If you want only one viewer connection include the \fB-once\fR option. .IP For "icon" the gui just a small standalone window. For "tray" it will attempt to embed itself in the "system tray" if possible. If "=setpass" is appended then at startup the X11 user will be prompted to set the VNC session password. If =<hexnumber> is appended that icon will attempt to embed itself in the window given by hexnumber. Use =noadvanced to disable the full gui. (To supply more than one, use "+" sign). E.g. \fB-gui\fR tray=setpass and \fB-gui\fR icon=0x3600028 .IP Other modes: "full", the default and need not be specified. "\fB-gui\fR \fInone\fR", do not show a gui, useful to override a ~/.x11vncrc setting, etc. .IP 5) When "geom=+X+Y" is specified, that geometry is passed to the gui toplevel. This is the icon in icon/tray mode, or the full gui otherwise. You can also specify width and height, i.e. WxH+X+Y, but it is not recommended. In "tray" mode the geometry is ignored unless the system tray manager does not seem to be running. One could imagine using something like "\fB-gui\fR \fItray,geom=+4000+4000\fR" with a display manager to keep the gui invisible until someone logs in... .IP More icon tricks, "icon=minimal" gives an icon just with the VNC display number. You can also set the font with "iconfont=...". The following could be useful: "\fB-gui\fR \fIicon=minimal,iconfont=5x8,geom=24x10+0-0\fR" .IP General examples of the \fB-gui\fR option: "x11vnc \fB-gui",\fR "x11vnc \fB-gui\fR ez" "x11vnc \fB-gui\fR localhost:10", "x11vnc \fB-gui\fR conn,host:0", "x11vnc \fB-gui\fR tray,ez" "x11vnc \fB-gui\fR tray=setpass" .IP If you do not intend to start x11vnc from the gui (i.e. just remote control an existing one), then the gui process can run on a different machine from the x11vnc server as long as X permissions, etc. permit communication between the two. .IP FONTS: On some systems the tk fonts can be too small, jagged, or otherwise unreadable. There are 4 env vars you can set to be the tk font you prefer: .IP X11VNC_FONT_BOLD main font for menus and buttons. X11VNC_FONT_FIXED font for fixed width text. .IP X11VNC_FONT_BOLD_SMALL tray icon font. X11VNC_FONT_REG_SMALL tray icon menu font. .IP The last two only apply for the tray icon mode. .IP Here are some examples: .IP \fB-env\fR X11VNC_FONT_BOLD='Helvetica \fB-16\fR bold' \fB-env\fR X11VNC_FONT_FIXED='Courier \fB-14'\fR \fB-env\fR X11VNC_FONT_REG_SMALL='Helvetica \fB-12'\fR .IP You can put the lines like the above (without the quotes) in your ~/.x11vncrc file to avoid having to specify them on the x11vnc command line. .PP \fB-remote\fR \fIcommand\fR .IP Remotely control some aspects of an already running x11vnc server. "\fB-R\fR" and "\fB-r\fR" are aliases for "\fB-remote\fR". After the remote control command is sent to the running server the 'x11vnc \fB-remote\fR ...' x11vnc command exits. You can often use the \fB-query\fR command (see below) to see if the x11vnc server processed your \fB-remote\fR command. .IP The default communication channel is that of X properties (specifically X11VNC_REMOTE), and so this command must be run with correct settings for DISPLAY and possibly XAUTHORITY to connect to the X server and set the property. Alternatively, use the \fB-display\fR and \fB-auth\fR options to set them to the correct values. The running server cannot use the \fB-novncconnect\fR option because that disables the communication channel. See below for alternate channels. .IP For example: 'x11vnc \fB-remote\fR stop' (which is the same as \(aqx11vnc \fB-R\fR stop\(aq) will close down the x11vnc server. \(aqx11vnc \fB-R\fR shared\(aq will enable shared connections, and \(aqx11vnc \fB-R\fR scale:3/4\(aq will rescale the desktop. .IP To use a different name for the X11 property (e.g. to have separate communication channels for multiple x11vnc's on the same display) set the X11VNC_REMOTE environment variable to the string you want, for example: \fB-env\fR X11VNC_REMOTE=X11VNC_REMOTE_12345 Both sides of the channel must use the same unique name. .IP To run a bunch of commands in a sequence use something like: x11vnc \fB-R\fR 'script:firstcmd;secondcmd;...' .IP Use x11vnc \fB-R\fR script:file=/path/to/file to read commands from a file (can be multi-line and use the comment '#' character in the normal way. The ';' separator must still be used to separate each command.) .IP To not try to contact another x11vnc process and instead just run the command (or query) directly, prefix the command with the string "DIRECT:" .IP .IP The following \fB-remote/-R\fR commands are supported: .IP stop terminate the server, same as "quit" "exit" or "shutdown". .IP ping see if the x11vnc server responds. return is: ans=ping:<display> .IP ping:mystring as above, but use your own unique string. return is: ans=ping:mystring:<xdisplay> .IP blacken try to push a black fb update to all clients (due to timings a client could miss it).

Both of these programs are for 'pointer and keyboard' sharing between separate X displays. In general the two displays are usually nearby, e.g. on the same desk, and this allows the user to share a single pointer and keyboard between them. The user moves the mouse to an edge and then the mouse pointer appears to 'jump' to the other display screen. Thus it emulates what a single X server would do for two screens (e.g. :0.0 and :0.1) The illusion of a single Xserver with multiple screens is achieved by forwarding events to the 2nd one via the XTEST extension. .IP What the x11vnc bcx_xattach command does is to perform some pointer movements to try to INDUCE xattach/x2x to 'jump' to the other display. In what follows the \(aqmaster\(aq display refers to the one that when it has \(aqfocus\(aq it is basically doing nothing besides watching for the mouse to go over an edge. The 'slave' display refers to the one to which the mouse and keyboard is redirected to once an edge in the master has been crossed. Note that the x11vnc executing the bcx_xattach command MUST be the one connected to the *master* display. .IP Also note that when input is being redirected (via XTEST) from the master display to the slave display, the master display's pointer and keyboard are *grabbed* by xattach/x2x. x11vnc can use this info to verify that the master/slave mode change has taken place correctly. If you specify the "ifneeded" option (see below) and the initial grab state is that of the desired final state, then no pointer movements are injected and "DONE,GRAB_OK" is returned. .IP "str" must contain one of "up", "down", "left", or "right" to indicate the direction of the 'jump'. "str" must also contain one of "master_to_slave" or "slave_to_master" to indicate the type of mode change induced by the jump. Use "M2S" and "S2M" as shorter aliases. .IP "str" may be a "+" separated list of additional tuning options. The "shift=n" option indicates an offset shift position away from (0,0) (default 20). "final=x+y" specifies the final position of the cursor at the end of the normal move sequence; default 30+30. "extra_move=x+y" means to do one more pointer move after "final" to x+y. "dt=n" sets the sleep time in milliseconds between pointer moves (default: 40ms) "retry=n" specifies the maximum number of retries if the grab state change fails. "ifneeded" means to not apply the pointer movements if the initial grab state is that of the desired final state. "nograbcheck" means to not check if the grab state changed as expected and only apply the pointer movements (default is to check the grab states.) .IP If you do not specify "up", etc., to bcx_xattach nothing will be attempted and the command returns the string FAIL,NO_DIRECTION_SPECIFIED. If you do not specify "master_to_slave" or "M2S", etc., to bcx_xattach nothing will be attempted and the command returns the string FAIL,NO_MODE_CHANGE_SPECIFIED. .IP Otherwise, the returned string will contain "DONE". It will be "DONE,GRAB_OK" if the grab state changed as expected (or if "ifneeded" was supplied and the initial grab state was already the desired one.) If the initial grab state was incorrect, but the final grab state was correct then it is "DONE,GRAB_FAIL_INIT". If the initial grab state was correct, but the final grab state was incorrect then it is "DONE,GRAB_FAIL_FINAL". If both are incorrect it will be "DONE,GRAB_FAIL". Under grab failure the string will be followed by ":p1,k1-p2,k2" where p1,k1 indicates the initial pointer and keyboard grab states and p2,k2 the final ones. If GRAB_FAIL or GRAB_FAIL_FINAL occurs, the action will be retried up to 3 times; trying to reset the state and sleeping a bit between each try. Set retry=n to adjust the number of retries, zero to disable retries. .IP Examples: \fB-R\fR bcx_xattach:down+M2S \fB-R\fR bcx_xattach:up+S2M \fB-R\fR bcx_xattach:up+S2M+nograbcheck+dt=30 \fB-R\fR bcx_xattach:down+M2S+extra_move=100+100 .IP or use \fB-Q\fR instead of \fB-R\fR to retrieve the result text. .IP End of the bcx_xattach:str description. .IP The .IR vncconnect (1) command from standard VNC distributions may also be used if string is prefixed with "cmd=" E.g. 'vncconnect cmd=stop'. Under some circumstances .IR xprop (1) can used if it supports \fB-set\fR (see the FAQ). .IP If "\fB-connect\fR \fI/path/to/file\fR" has been supplied to the running x11vnc server then that file can be used as a communication channel (this is the only way to remote control one of many x11vnc's polling the same X display) Simply run: 'x11vnc \fB-connect\fR /path/to/file \fB-remote\fR ...' or you can directly write to the file via something like: "echo cmd=stop > /path/to/file", etc. .PP \fB-query\fR \fIvariable\fR .IP Like \fB-remote,\fR except just query the value of \fIvariable\fR. "\fB-Q\fR" is an alias for "\fB-query\fR". Multiple queries can be done by separating variables by commas, e.g. \fB-query\fR var1,var2. The results come back in the form ans=var1:value1,ans=var2:value2,... to the standard output. If a variable is read-only, it comes back with prefix "aro=" instead of "ans=". .IP Some \fB-remote\fR commands are pure actions that do not make sense as variables, e.g. "stop" or "disconnect", in these cases the value returned is "N/A". To direct a query straight to the X11VNC_REMOTE property or connect file use "qry=..." instead of "cmd=..." .IP ans= stop quit exit shutdown ping resend_cutbuffer resend_clipboard resend_primary

passwd viewpasswd .PP \fB-QD\fR \fIvariable\fR .IP Just like \fB-query\fR variable, but returns the default value for that parameter (no running x11vnc server is consulted) .PP \fB-sync\fR .IP By default \fB-remote\fR commands are run asynchronously, that is, the request is posted and the program immediately exits. Use \fB-sync\fR to have the program wait for an acknowledgement from the x11vnc server that command was processed (somehow). On the other hand \fB-query\fR requests are always processed synchronously because they have to wait for the answer. .IP Also note that if both \fB-remote\fR and \fB-query\fR requests are supplied on the command line, the \fB-remote\fR is processed first (synchronously: no need for \fB-sync),\fR and then the \fB-query\fR request is processed in the normal way. This allows for a reliable way to see if the \fB-remote\fR command was processed by querying for any new settings. Note however that there is timeout of a few seconds (see the next paragraph) so if the x11vnc takes longer than that to process the requests the requester will think that a failure has taken place. .IP The default is to wait 3.5 seconds. Or if cmd=stop only 1.0 seconds. If cmd matches 'script:' then it will wait up to 10.0 seconds. Set X11VNC_SYNC_TIMEOUT to the number of seconds you want it to wait. .PP \fB-query_retries\fR \fIstr\fR .IP If a query fails to get a response from an x11vnc server, retry up to n times. \fIstr\fR is specified as n[:t][/match] Optionally the delay between tries may be specified by "t" a floating point time (default 0.5 seconds.) Note: the response is not checked for validity or whether it corresponds to the query sent. The query "ping:mystring" may be used to help uniquely identify the query. Optionally, a matching string after a "/" will be used to check the result text. Up to n retries will take place until the matching string is found in the output text. If the match string is never found the program's exit code is 1; if the match is found it exits with 0. Note that there may be stdout printed for each retry (i.e. multiple lines printed out to stdout.) Example: \fB-query_retries\fR 4:1.5/grab_state .PP \fB-remote_prefix\fR \fIstr\fR .IP Enable a remote-control communication channel for connected VNC clients. str is a non-empty string. If a VNC client sends rfbCutText having the prefix \fIstr\fR then the part after it is processed as though it were sent via 'x11vnc \fB-remote\fR ...'. If it begins with neither 'cmd=' nor 'qry=' then 'qry=' is assumed. Any corresponding output text for that remote control command is sent back to all client as rfbCutText. The returned output is also prefixed with \fIstr\fR. Example: \fB-remote_prefix\fR DO_THIS: .IP Note that enabling \fB-remote_prefix\fR allows the remote VNC viewers to run x11vnc \fB-remote\fR commands. Do not use this option if they are not to be trusted. .PP \fB-noremote,\fR \fB-yesremote\fR .IP Do not process any remote control commands or queries. Do process remote control commands or queries. Default: \fB-yesremote\fR .IP A note about security wrt remote control commands. If someone can connect to the X display and change the property X11VNC_REMOTE, then they can remotely control x11vnc. Normally access to the X display is protected. Note that if they can modify X11VNC_REMOTE on the X server, they have enough permissions to also run their own x11vnc and thus have complete control of the desktop. If the "\fB-connect\fR \fI/path/to/file\fR" channel is being used, obviously anyone who can write to /path/to/file can remotely control x11vnc. So be sure to protect the X display and that file's write permissions. See \fB-privremote\fR below. .IP If you are paranoid and do not think \fB-noremote\fR is enough, to disable the X11VNC_REMOTE property channel completely use \fB-novncconnect,\fR or use the \fB-safer\fR option that shuts many things off. .PP \fB-unsafe\fR .IP A few remote commands are disabled by default (currently: id:pick, accept:<cmd>, gone:<cmd>, and rawfb:setup:<cmd>) because they are associated with running external programs. If you specify \fB-unsafe,\fR then these remote-control commands are allowed. Note that you can still specify these parameters on the command line, they just cannot be invoked via remote-control. .PP \fB-safer\fR .IP Equivalent to: \fB-novncconnect\fR \fB-noremote\fR and prohibiting \fB-gui\fR and the \fB-connect\fR file. Shuts off communication channels. .PP \fB-privremote\fR .IP Perform some sanity checks and disable remote-control commands if it appears that the X DISPLAY and/or connectfile can be accessed by other users. Once remote-control is disabled it cannot be turned back on. .PP \fB-nocmds\fR .IP No external commands (e.g. .IR system (3) , .IR popen (3) , .IR exec (3) ) will be run at all. .PP \fB-allowedcmds\fR \fIlist\fR .IP \fIlist\fR contains a comma separated list of the only external commands that can be run. The full list of associated options is: .IP stunnel, ssl, unixpw, WAIT, zeroconf, id, accept, afteraccept, gone, pipeinput, v4l-info, rawfb-setup, dt, gui, ssh, storepasswd, passwdfile, custom_passwd, findauth, crash. .IP See each option's help to learn the associated external command. Note that the \fB-nocmds\fR option takes precedence and disables all external commands. .PP \fB-deny_all\fR .IP For use with \fB-remote\fR nodeny: start out denying all incoming clients until "\fB-remote\fR \fInodeny\fR" is used to let them in. .PP These options are passed to LibVNCServer: .PP \fB-rfbport\fR \fIport\fR .IP TCP port for RFB protocol .PP \fB-rfbwait\fR \fItime\fR .IP max time in ms to wait for RFB client .PP \fB-rfbauth\fR \fIpasswd-file\fR .IP use authentication on RFB protocol (use 'x11vnc \fB-storepasswd\fR pass file' to create a password file) .PP \fB-rfbversion\fR \fI3.x\fR .IP Set the version of the RFB we choose to advertise .PP \fB-permitfiletransfer\fR .IP permit file transfer support .PP \fB-passwd\fR \fIplain-password\fR .IP use authentication (use plain-password as password, USE AT YOUR RISK) .PP \fB-deferupdate\fR \fItime\fR .IP time in ms to defer updates (default 40) .PP \fB-deferptrupdate\fR \fItime\fR .IP time in ms to defer pointer updates (default none) .PP \fB-desktop\fR \fIname\fR .IP VNC desktop name (default "LibVNCServer") .PP \fB-alwaysshared\fR .IP always treat new clients as shared .PP \fB-nevershared\fR .IP never treat new clients as shared .PP \fB-dontdisconnect\fR .IP don't disconnect existing clients when a new non-shared connection comes in (refuse new connection instead) .PP \fB-httpdir\fR \fIdir-path\fR .IP enable http server using dir-path home .PP \fB-httpport\fR \fIportnum\fR .IP use portnum for http connection .PP \fB-enablehttpproxy\fR .IP enable http proxy support .PP \fB-progressive\fR \fIheight\fR .IP enable progressive updating for slow links .PP \fB-listen\fR \fIipaddr\fR .IP listen for connections only on network interface with addr ipaddr.
