It depends on what you do on the net. For example, some irc servers
(irc.prison.net is one of tehm) require for you to run ident in order to
connect to them.
Obviously, you wnat to turn off useless ports...discard, daytime, time,
finger, etc.
Just go into /etc/inetd.conf and comment out services you don't want inetd
to listen for. Like telnet.....if you want to have outside access into
machine, use ssh (port 22).
So really you can have all ports closed off, that can be closed
with inetd, but you will still need ipchains to secure other ports lke
6000 (X).
To see the list of ports open on your machine, netstat or nmap yourself.
