Assuming you have a telnet daemon running on all the *nix machines and each
machine displays the /etc/issue file (some distros use /etc/issue.net).  You
could use regex to extract the hostname.

You could also use nmblookup to get *nix machine names if each machine has
samba installed and running nmbd.

Anyways, this is not the list to discuss such topics.
