Recently, I wrote an article about How to scan your Linux-Distro for Root Kits.
Now that the machine is... clean! I think, a good thing TO-DO, is to test my Firewall (AGAIN !!!)
The good news are that we can use the free tool FTester.
The bad news are that FTester needs to be configured right...
So... Let's get to work !
What is FTester ?
The Firewall Tester (FTester) is a tool designed for testing firewalls filtering policies and Intrusion Detection System (IDS) capabilities.
The tool consists of two perl scripts, a packet injector (ftest) and the listening sniffer (ftestd).
