So, if you don't open that port, you will not be able to connect to your box via ssh. And with ssh you can also do fancy things like X11 forwarding. I like it. Nomad Nomad - openSUSE is great as well. Whatever, regards and good luck!

I agree, the x11 forwarding is very cool. I SSH into my campus machine all the time to run my Cadence VLSI tools(Im a student at UCSC, EE major).

Yast - Security and Users - Firewall - Allowed Services

In the drop box look for Secure Shell Server and select then click the add button, then next and thru to the finish.

Just wanted to mention. I also use a kde3 application, even now I am using it in kde4 and SUSE 11.2 which doesn't even come with kde3.
It's called kde3-kssh
And can be added from this repo in 11.1: Index of /repositories/KDE:/Community/openSUSE_11.1

Just enter the LAN IP the Server Username and password
It open a terminal which on the server. So for example, if you type in there firefox, it will open the FF browser from the Server in your remote machine.

X-forwarding is quite slow over GPRS and even 3G/UMTS.

If a GUI/desktop over Internet is interesting I think FreeNX is far the
best. It works fine over 3G and is usable even over GPRS.

It has come with openSUSE at least till version 11.0.
It seems to have been dropped in 11.2.
But it can be easily obtained in two versions, NoMachine and GPL

I can leave my KDE session on my desktop and then attach the same
session somewhere else with my laptop, anywhere I like.

So the same session can go on anywhere, anytime, with any machine
running the client.

to your note about NX, vahis. I was using it and very much liked it with R11.0 but it doesn't work in R11.1 i get some errors on the client when trying to connect which I was not able to resolve them. Not sure if you upgraded to 11.1 and still using it. If yes maybe a different thread would be better to continue our comments.
Sorry for changing the thread topic.

Worth mentioning that opening this service to the network (or, worse, the internet) creates a security problem as people can just keep guessing passwords as rapidly as they like.

You should as a minimum make sure 'root' is listed in 'deny users' part of sshd.config, and think seriously about something like sshdfilter or fail2ban to shut down connections that guess wrongly frequently.
