Disable inetd and rpc.portmap.
You might also want to disable sendmail, sshd, etc... depending on your
configuration.
To check if there are any processes listening, do a:
netstat --inet -a
With lsof, you might also know which process opens which socket, etc...
Basically, if no process have a listening socket on your machine, then no one
will get in.
This is the only 100% safe (but drastic) solution.
