bring an uncompromised "netstat" on the machine and when you run "netstat 
-anp|grep LISTEN" you'll see that a shell has been bound to the ports listed 
above. Connecting to those an attacker can gain root access on your machine 
without authorization.

You can use LSOF (grab the RH6.2 RPM for i386 and bring it onto the machine) 
to find out which processes are responsible for this.

But I'd look at the following places:

/etc/inetd.conf
/etc/rc.d/rc.local
/etc/rc.d/rc.sysinit

If that search turns out blank, then check the rest of the init scripts in 
/etc/rc.d/init.d/ for suspicious additions.

Does chkrootkit show that any of the system binaries has been replaced?
