Opening a port on SuSe Firewall

Hockeyfan · 10-11-2005, 02:45 PM

How do I open a port on a Suse 9.3 firewall? Also How do I find out all ports that are in use on my computer? I've done it before with a comand, I think it was nstat but I'm not sure.

Using YaST's firewall config program is the easiest way.

Try

Code:

netstat -atun

This will show you listening tcp and udp ports, and active network connections.

If you want to know which ports are open to your network, though, you'll want to run nmap against it from another machine on the same network.

can you not use:

nmap -v -sS -O 127.0.0.1

That's the example given at the bottem after typing simply "nmap." That's what a friend of mine suggested, so I did that on my machine, and it showed me which ports were open. I took measures to close them and nmap reflected the changes.
