OK, that raises yet another ?. How do you close ports?
Deactivating the network service you do not need. For example by editing /etc/inetd.conf and commenting out everything you do not need, or just turning of inetd from within yast2. You can configure inetd from within yast2 any way. You could also stop every standalone service you do not need, for example apache (web server), or ssh, using the runlevel editor. Next question (I guess): what is a runlevel? You should read "man inittab" and /etc/inittab only (Do not edit /etc/inittab if you do not know what you are doing!). A runlevel is a "level" of the system. If you are in one runlevel, some services are on, if you move on another runlevel, some other services are on. Still about security: netstat -a let you know what ports are listening. Moreover: there is a script called hardensuse, that should disable EVERY service, so you need ot turn on those you really need.
