I doubt that the server would be denying service to my computer in particular
since the one next door with a similar IP and DNS connects fine via ssh.
I cannot look at the host files under /etc. Is it possible that the
server is conigured to deny service to all hosts that do not have
DNS lookup? Where would I find such a setting?

Thanks,

Neil
