About Linux firewalls


Recommended Posts

Hello everybody.



I am currently looking for a Linux firewall that behaves just like Zone Alarm for Windows. I know about firestarter and mandriva's own interactive firewall, but what I need is something that immediately warns me of a program trying to connect to the internet so I can block it, for example.


Do you know of any way to achieve this with Linux?

To be honest, I’ve never heard of such a program on Linux, although it should be possible to do… Good luck. I’d be interested in an answer too, even if I have no use for it myself.

Well, I have found two interesting things. But I do require your help because both apparent solutions are beyond my abilities:




1 - http://tuxguardian.sourceforge.net/index.php


2 - http://ubuntuforums.org/showthread.php?t=1188099



Solution 1 seems to be an easy-to-use program, but I didn't find it for Mandriva 2010, and I'm not sure if I can get the dependencies to install it by compiling since I use KDE4 and it requires QT3.


Solution 2 is nice, it's not exactly what I expect (that would be solution 1), but I could make do with it if I just understood what it's about.



Can somebody help me?

I had a look at TuxGuardian. It seems to be a nice program, and it should be feasible to install it. So… as daniewicz said, “I could try to walk you through option #1. Give me some specific questions.†;-)

I'm sorry for the incredibly late reply. I "lost" the Linux machine I wanted to try this on, but here I am again.


Firewall3d, thank you for your suggestion too. I'll see which of these suits me better.



Thank you everybody




Update: I'm getting this error when I try to launc lpdflower via terminal:

Any Ideas?
