    The domain-name and hostname appear to have been compromised.  Use the
netconfig tool to rebuild both as you require, and ensure that the IP
address is also
intact (I suspect it isn't).  Since both name and/or IP are involved in
received telnet,
rlogin, etc., this is almost certainly why you can't communicate with the
machine.

    I would recommend in the future trying to telnet to both the IP and
host-domainname
for your server, as only the DNS stuff may be inactive [i.e; the resolv.conf
file in /etc is
whacked and/or your /etc/hosts file is gone].

    Good luck!
