I think the correct answer about what services to run is *none*. Shut

use this command to see if you have anything listening:

netstat -taun [enter]

Running netstat -taun returns:

127.0.0.1 listening on ports 2544 (novell-zen) and 25 (smtp)
::1:25 listening on port 25 (smtp)

Can I, and if so, how do I, terminate these services?

Obviously I use e-mail, but I don't want suse to listen for smtp all the
time.

We need a Suse/Novell expert to explain exactly how to shut them
down. All I can suggest is to follow the details of the startup scripts
until you find out how they start.

On a debian machine, the startup scripts are all located in /etc/init.d so
I just go there and make the ones I don't want to run non executable like
this:

#chmod -x somescript

Then the startup/shutdown sequence will try to run the script and you will
see "permission denied" messages. Messy, but it works.

I don't know what "novell-zen" is and I don't know how to interpret
"::1:25". Can someone explain?
