VNC over SSH

VNC over SSH is one of the secure ways to remotely access computer desktop.

At the server side (the remote computer which you want to log to):
vncserver :64 -geometry 1024x768 -depth 16 -name user

At the viewer side (the local computer you are using now):
vncviewer -via 192.168.1.2 localhost:64

192.168.1.2 is the server' IP.

After you finish, kill the process at server:
vncserver -kill :64
