Craig,

Do you have an entry for the remote host you are login in from
in your /etc/hosts file?

telnet hangs if it can't get reverse dns on a host.

Try "nslookup remotehost" and see what you get.

Yes I do have it in the hosts file.  Would this cause me not being able to telnet to my machine from my machine?
