I am using Etch with kernel 2.6.15-1-686.
To install the firestarter:
Code: Select all
apt-get install firestarter
There is an excellent documentation for Firestarter here (Read this first).
It is extremely easy to setup and use. As a default setting, all the inbound connections are blocked but you are freely allowed to established new connections. All the blocked connections with IP addresses are logged very clearly. You can even view currently active connections with all IP addresses and port numbers in use. You can configure more in-depth according to your needs later on. I must say that it is a very cool software. During last 3 hours, Firestarter has blocked 313 inbound connections which I don't authorize and out of 313, 303 is serious (uni campus LAN). These are the informations I got from the Status tab in Firestarter. No harm at all, you should try it if you are looking for a firewall solution.
