------
by default, telnet server daemon is not turned on in RH 7.1 / 7.2

the first thing you should do is ipchains -L and iptables -L - to see
what ports are blocked.

then you should netstat -an to see what ports are listening

and finally, you can install nmap - if you don't find it on the cd's
distributed by RH - which I am too lazy to check right now, you are
certain to find it on freshmeat.net or
ftp://ftp.redhat.com/pub/contrib/libc6/i386/
