Firewall Question

snatale1 · 08-13-2003, 03:37 PM

I've noticed alot of firewall questions, some from the very exp. (I'm guessing from # of posts) ya i'm new. anyways i'm running RH9 is the firewall that comes with the disrtro crap? If so what would be a good one to get I see alot of talk about GuardDog. Also I know (or have been told) that virus infection in Linux is impossible (or very rare) should I still have a scanner? if so any recomendations? Still trying to get all those years of windows out of my head, ya know?

THANX

Kernel 2.4.x has a firewall subsystem called iptables.
The firewall sofware for Linux are basically front-ends to iptables.

In RedHat 9, you can use Security Level (redhat-config-securitylevel).

Or you can try other GUIs like:
FireStarter
http://firestarter.sourceforge.net/
Shorewall

But if you want to learn how to set up iptables manually.
Netfilter has documentation and tutorials.

Computer viruses...

I did not know such a thing existed.

Unless you plan on setting up a mail server for windows clients, you don't need one.

But if you want one...

In the end, when you download an unknown or suspicious binary or script, don't run it as root (or at all for that matter).
