Comment out any services you don't absolutely need in /etc/inetd.conf and create an /etc/hosts.allow and /etc/hosts.deny file and make them as restrictive as you can. You also might want to install tripwire and run it and save it's output to a removable media for future reference should you find you have been or might have been cracked.
I would also add that you might want to not receive mail using sendmail (unless you want to do *quite a bit* of very hefty reading. Also, if you need telnet and ftp, use ssh instead. Cheers, Dennis "Custard pies are a sort of esperanto: a universal language." --Noel Godin
