/etc/services is a listing of services,

/etc/inetd.conf or /etc/xinetd.conf is probably where you want to
edit out services that are acuatlly listening...

inetd listens on the open ports and starts the daemon required for
the job on demand. to turn off the unwanted ports, you need to use

 netstat -an 

to see what ports are open, then refer to /etc/services to see what
service the port number refers to, and comment it out in /etc/[x]inetd.conf
