I too run tunnels, as in: [EMAIL PROTECTED]> ssh 5902:localhost:5901 [EMAIL PROTECTED] Where I am telling it to pass the local (to nassau) port 5901 to 5902 at kushana. Yes, I am running vnc in the above example and I have the same username in both machines. I am lazy! ;) BTW, I do not know if it is important but I do have AllowTcpForwarding enabled in my sshd_config in nassau.
