Try finding the line in the file /etc/inet.conf and comment it out for the
services that you don't want to run. You may have to reboot then, or try
restarting the internet superserver - try a "/etc/init.d/inetd restart". You
might have to kill a few other processes or just stop them using their scripts
in /etc/init.d/.
Hope this helps
