VNC 4.1.2 Binary Distribution for Unix platforms

This software is distributed under the GNU General Public Licence as published by the Free Software Foundation. See the file LICENCE.TXT for the conditions under which this software is made available. VNC also contains code from other sources. See the Acknowledgements section below, and the individual files for details of the conditions under which they are made available.

There are six programs here:

vncviewer - this is the VNC viewer, or client, program for X.

Xvnc - this is the X VNC server - it is both a VNC server and an X server

         with a "virtual" framebuffer.  You normally use the vncserver script
         to start Xvnc.

vncserver - this is a wrapper script which makes starting an X VNC server

              (i.e. desktop) more convenient.  It is written in Perl, so to use
              the script you need that.

vncpasswd - this program allows you to change the password used to access

              your X VNC desktops.  The vncserver script uses this program when
              you first start a VNC server.

vncconfig - this program is used to configure and control a running instance

of Xvnc.

x0vncserver - this is an inefficient VNC server which continuously polls any

                X display, allowing it to be controlled via VNC.  It is
                intended mainly as a demonstration of a simple VNC server.

In addition to these standalone programs, on Linux platforms this distribution can also be used to turn a native XFree86 version 4 X server into a VNC server. This is done using a module loaded at run-time. On other platforms, VNC support can only be added by replacing the native X server binary - you must build from the source distribution if this is what you want.

You need a reasonably recent version of the X window system installed. This come as standard with most unix machines. If you don't have it installed, see http://www.xfree86.org or http://www.x.org

You should copy the programs to some directory which is in your PATH environment variable, such as /usr/local/bin. You can use the vncinstall script to do this for you:

% ./vncinstall /usr/local/bin

This will also attempt to install the manual pages in an appropriate directory. You can specify an alternative directory as a second argument to vncinstall:

% ./vncinstall /usr/local/bin /usr/local/man

It will also try to install the vnc.so XFree86 version 4 module if appropriate. This will be copied to the /usr/X11R6/lib/modules/extensions directory and can be enabled like any other module by adding a Load "vnc" line to the Module section of XF86Config. The parameters listed in the Xvnc manual page can be set as options in XF86Config e.g. Option "passwordFile" "/root/.vnc/passwd". Note that for some reason options cannot be set in the Module section of XF86Config - try the Screen section.

If you want to use the Java VNC viewer, you should copy the files from the java directory to some suitable installation directory such as /usr/local/vnc/classes:

% mkdir -p /usr/local/vnc/classes
% cp java/* /usr/local/vnc/classes

We recommend that you use the vncserver script to run Xvnc for you. You can edit the script as appropriate for your site. Things you may need to change include:

The location of Perl - if Perl is not installed in /usr/bin you'll need to edit the "#!/usr/bin/perl" first line of vncserver.
Xvnc's font path and color database. If you have an installation of X which is not in the standard place you may need to add arguments to the Xvnc command line to set these. These should be appended to the $cmd variable at the comment "# Add font path and color database...".
$vncJavaFiles - this specifies the location of the files for the VNC viewer Java applet. The default is /usr/local/vnc/classes.
