[nmglug] Remote Desktop Tunneling

[Andrew Farnsworth]

Oh, and just to be clear, the portion of the line below which is 
"username at host1$" is the prompt at your local machine, it is not 
something you type.  The command you want is the "ssh -L 
5901:localhost:5900 username at host2"  which will connect you to the 
machine host2 over ssh.
