Except that the X forwarding doesn't work! It should work as expected if you just skip the tunnel and use two ssh connections: imadev:~$ ssh -t -X vandev ssh -X arc1 xdpyinfo RSA host key for IP address '10.76.142.101' not in list of known hosts. wooledg@vandev's password: Warning: No xauth data; using fake authentication data for X11 forwarding. Password: name of display: localhost:11.0 version number: 11.0 vendor string: Hewlett-Packard Company vendor release number: 600000 ... Of course you'll need xauth(1) on all three machines, and X11Forwarding in the sshd_config files on all but "hal". The -t option on the first ssh is so that there's a terminal in which the sshd on box #2 (vandev in my example) can ask for a password. This shouldn't be needed if you use keys.
