VNC (an abbreviation for Virtual Network Computing) is a great client/server
software package allowing remote network access to graphical desktops. With
VNC, you can access your machine from everywhere provided that your machine
is connected to the Internet.

Installation of tightvnc
Install tightvnc by running the following commands:
xmkmf
make World
cd Xvnc
/configure
make -s
./vncinstall /usr/vnc/bin /usr/vnc/man
mkdir /usr/vnc/classes
cp classes/* /usr/vnc/classes

Configuring kdm
Important NOTE:: Files may be in a different location. It depends on your
installation.
Config files
/etc/X11/xdm/xdm-config
Comment out the entry "DisplayManager.requestPort: 0" by adding a !.
The line should look like this "! DisplayManager.requestPort: 0".
/opt/kde3/share/config/kdm
Locate the line XDMCP and change it from false to true.
/etc/X11/xdm/Xaccess
Uncomment out the entry "# * #any host can get a login window" by remove the
first #. The line should look like this " * #any host can get a login window".
----
Configuring gdm
Important NOTE:: Files may be in a different location. It depends on your
installation.
Config files
/etc/X11/xdm/xdm-config
Comment out the entry "DisplayManager.requestPort: 0" by adding a !.
The line should look like this "! DisplayManager.requestPort: 0".
Run gdm-config
Start gdmconfig. Select Expert Mode. Ensure that Enable XDMCP is
checked
Locate the line XDMCP and change it from false to true.
/etc/X11/xdm/Xaccess
Uncomment out the entry "# * #any host can get a login window" by remove the
first #. The line should look like this " * #any host can get a login window".

Final Step
Reboot the machine. After reboot go to another computer and try the following.
You will need to load the vncviewer on another computer to test. There are clients
for Windows and Unix. The java viewer is not supported under this configuration.
To connect to your server you will need to start the vncviewer. Enter in the IP address
or the FQDN of the service with the last two numbers of the port you want to connect
to. In our suggested installation here is a list of the ports and associated desktop
configurations.
Example: vnc.server.com:60
Would connect to vnc.server.com at 640x460 16 bit color
