I do succeed in connecting to ririu. Except that the X forwarding doesn't work!
It should work as expected if you just skip the tunnel and use two
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.
Warning: No xauth data; using fake authentication data for X11 forwarding.

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.
