Step one: Open /etc/inetd.conf (make a backup first)
Step two: Find the shell, login, and exec entries and put a "#" in the first
column of them.
Step three: Save /etc/inetd.conf
Step four: run ps -ef to find out the PID of inetd.
Step five: kill -HUP [inetd PID]
You have just turned off the all the r-command servers on your box.
This is *very* worthwhile, as the r-commands are severely insecure.
Replace with opensshd if the functionality is still required.
