Disable ports

john.s · 06-04-2006, 01:18 AM

I have redhat fc4. I've been using it for about 4 days now and I'm still not convinced about the security. I haven't even checked my email yet with linux haha.

Security comes first, right? Anyway....

I need some help disabling ports 111(sunrpc), 631(IPP), 55555, and 5335.

So instead of using iptables to block the above, is there another way to block it?

iptables is how you block ports, there are GUI frontends like Firestarter and Guarddog but they just run iptables commands in the background.

May I suggest rather than blocking the ports, why not stop the services that are running on those ports? Then you have not only added security but it'll ease up on your system resources.

Why? What's wrong with blocking ports with iptables?

Yes I tried to disable the services, but I just couldn't find them. I googled but couldn't find the right information. If you or someone can help me find and disable the rpc services then that would be great.

What is the command to find rpc services that are running on my system(redhat fc4)

Oh yea by the way, the command chkconfig doesn't seem to work for me. Did I type something wrong?
