SSH Tunnel command
Command to setup the tunnel
ssh -N -p 11000 firstname.lastname@example.org -L 5901/localhost/5900
To view from Local computer
So the first command sets up the tunnel from the local machine to the remote computer using port 11000. The 5901 port on the local machine is forwarded to the 5900 port on the remote machine. Now when you use your local machine to connect to port 5901 on the localhost this allows you to connect to the vnc server on the remote machine via the port 11000 tunnel.
