Hi..

First of all.. Don't remove stuff from /etc/services.. thats not the
way to go!!!! If you have a backup of the original services file
i suggest you replace the one you modified with the orginal.. or simply copy it from
another box running the same OS and version...

Please tell me what os you are running ! That really helps..
To check for open ports try: netstat -a |grep LISTEN (should work
on most unixes)

you should check the /etc/inetd.conf
for services and comment them out.. example:

pop3 stream tcp nowait root /usr/sbin/popa3d popa3d

line in /etc/inetd.conf will enable POP3 mail services..
just comment it out to disable it with a
# sign in front like this!

#pop3 stream tcp nowait root /usr/sbin/popa3d popa3d

then find out the pid of inetd and run kill -HUP <PID_OF_INETD_HERE> or simply reboot the server...

You should also check your startup files f�r services (depends on OS and init type where to find them.. please tell me what os you are running. This could be done with the command: uname -a)

You could also checkout if there is a free firewall available for your unix/linux if you want more control of what to let in and out of a server.

Hope this helps some..
