Hi,
I recommend you install both iptables and Bastille. Avdven, gave you a link to the iptables tutorial by Str34m3r. I recommend you peruse it well. This link is your friend. www.rpmfind.net. I wouldn't recommend that you try to install any programs that you have to compile right now. Look for the rpm versions if available. If iptables and Bastille didn't come with the downloaded version of Mandrake 8.2, you might be able to find them at www.rpmfind.net. iptables is the Linux firewalling program for the 2.4 series kernel (which Mandrake 8.2 uses.). It works. To install iptables, open Software Manager. You will have to supply your root password when it comes up. Put iptables in the Software Manager search engine, and hit search. If it doesn't come up, you'll have to find it on the internet. Software Manager is pretty straightforward to use. After you install the iptables rpm, open a terminal (use Konsole with KDE). Login as root. At the command prompt type su root , then when the password prompt comes up, type your root password. You have to be logged in as root to work with iptables. Find the link to Str34m3r's iptables tutorial. He walks you through how to set them up. To make it easier for you, I recommend just allowing all outbound connections. So for the Output rules, the command you would enter would be iptables -P OUTPUT ACCEPT After you enter each command you need to hit the ENTER button. Also, this is important, you need a way to make sure you have a way to make sure your iptables firewall starts up at boot. After you enter all your rules, do this: enter this at the command line: iptables-save> /etc/iptables.conf This will create a file in your /etc directory containing your iptables rules. Ok, next do this. Go to your rc.local file. in the /etc directory. Find rc.local, and open it with a text editor. In your rc.local file, underneath the very last entry, type this: iptables-restore /etc/iptables.conf (Type it exactly like this. Do not use the > that you used with the save command.) Save your changes and close the text editor. Reboot your computer. If you did everything exactly like this, your firewall should be in effect. Go to www.grc.com and take the ShieldsUp port scan test. If it works, the tested ports should be stealthed. To see a list of your rules, type: iptables -L at the command line while logged in as root. This should bring up a list of the rules you have in effect.

Just a couple of brief pointers regarding Linux: Read! Read ! Read! Don't Give up! Don't give Up! Don't Give up!
