[YLUG] ssh

[Tom Hayward]

I couldn't figure what the terms of using ssh.y.a.u were, the sns faq
says you can use ssh, the old? faq (or at least another one) says you
can use ssh via ssh.y.a.u, and then the server replies to an attempt
to connect with:

This machine is the offcampus gateway and is not available for use on campus
Connection to ssh.york.ac.uk closed.

so I really don't know what the actual policies are.

Is there a definite server that I can and may ssh to from here?
I'm happy to port forward, or even daisy chain port forwarding... but
I just don't know what goes.
