Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

If you just want a firewall for an internet box and since you are using Mandrake, the easiest thing would be to go to Mandrake Control Center---type drakconf or mcc at a root prompt or click the icon if it is on the desktop and give your root password.
Anyway, once there, go to Security -> Firewalling and choose to configure the tinyfirewall. Again, if you are just surfing and not running a server, choose all the default, no server settings, choose to save settings on the last page.
This is what I do and the security scans at Steve Gibson's site or at dslreports both show "Stealth" for all ports scanned.
Thanks Aussie, but this is still way over my fragile little Linux newbie head.
I'm connecting to the web with a Mandrake8 box through (LAN) a w98se box by way of ICS. The w98se box runs ZA, and as for the Mandrake8 box, I have no idea if or how the firewall (Tiny?) is running.
What I wonder is which firewall will be the working one? Or would both of them be active?
I am a linux newbie too so I may not know what Im talking about, but it is my impression that the Mandrake "firewall" just consists of turning off servers that you dont use. If the server is off then the port is closed, it is not actually software you run but rather a wizard that turns off software you dont need.
Ipchains is the one that blocks incoming stuff by IP adress. (I think) and if you are using it then you should see a message that IPchains is being started when you boot.
scroll most of the way down and then
click on the Shields Up Banner, and this
conducts two tests...
1. Test My Shields
2. Probe My Ports
It's setup to check all ports on your PC, and try to access them, and then you geta report at the end as to the results of the probing, and then he gives you Xplainations for each result..check it out
it put my mind at ease
Ok, In mandrake Control Center >> Security >> Firewall sets up "Tiny Firewall" using ipchains if your using a 2.2.x kernel and iptables with the 2.4.x kernel. Both of those are quite secure and there are no virus's you can catch from email or surfing with linux. The main danger with a linux box is a phyiscal attack on your system leaving a "root exploit" behind. One of the first things that usually happens in a root exploit is "/sbin/ps" is replaced by a hacked version to hide any suspect deamons that the attacker might have left behind. A genuine "ps" should be around 60kb and a bad one would be around 10kb. I'd recomend you download portsentry on its own and set it up as per the default instructions in the "readme" and it will report all portscans to /var/log/messages as well as automagicly blocking the ip of the scanning computer.

trust me tho... you're not going to be needing linux anti-virus any time soon, if ever.
What about root kits? I here those are a problem for linux. What about spyware/adware?
