I need an advice on Red Hat 9 firewall

zebra90210 · 11-29-2003, 02:02 AM

Hi.

I've just installed the Red Hat 9. It's a nice system, and the installation went pretty easily, without any hiccups. LOL
I've tested the system firewall and it had two leaks, on ports 0 and 1.
Can somebody advice me how to fully stealth these two ports? I use GRC.com/shieldsUp to test the system.
I've used the Madrake for three years ( me happy, me likee! no more Windblows! ) and I just wanted to try a different 'flavor' of Linux. I liked the Red Hat but these leaks in the firewall were not acceptable.

Help!

Just download Guarddog here. Best thing I ever did and it has an excellent help file and tutorial. Shields Up! reports all ports stealthed.

The Linux built-in firewall subsystem is called iptables.
You can get many HowTOs and documention at netfilter/iptables.

Or you can use a GUI interace.
