You don't have an _external_ hardware firewall (like a cable/dsl router), do
you? Those will block all incomming traffic by default... (Probably a dumb
question.)
Failing that, are you using xinetd for sshd as well? On my system, I simply
disable it and run it as a daemon. It should be possible to run it thru
xinetd, but I'm not sure why you would. If you do, you may need an
/etc/hosts.allow entry like:
sshd: ALL
(Not sure if/how having it on port 80 will affect things... But make sure
that there are no conflicting services (like apache) bound to port 80.)
Also, have you tried looking for the relevant log files? There should be an
xinetd.log somewhere--according to the man page at least... If nothing else,
try "grep -r xinetd *" and "grep -r sshd *" from the /var/log directory.

The vermine is a small black and white relative of the lemming, found in
the cold Hublandish regions. Its skin is rare and highly valued, especially
by the vermine itself; the selfish little bastard will do anything rather
than let go of it.
