In a nutshell, you port forward some port near 5900 (the vnc port) on the local machine to port 5900 on the machine running the vnc server. This is done in your ~/.ssh/config file. For example: LocalForward 5925 192.168.0.5:5900 You then run: vncclient localhost:25 and it will connect through the secure tunnel to port 5900 on the target machine. In the example 192.168.0.5 For X, the task is even easier. Run: ssh -X -Y remote_machine.my.domain (where remote_machine.my.domain is the other machine) and X will be forwarded back to the local machine. If this does not work, check the /etc/ssh/sshd_config to make sure X11 tunnelling is allowed. (search for X11 in the file). Bob Styma
