alcanfw - A Linux Client Application+Netfilter FireWall

This was just something that has been up in my head for a long time.

Some times Im super paranoid, and I just want to make sure the right

stuff only talks on to the network. This is not as flexible and cool

as I dreamt of, but rather a quick script made in 2-3h that will work

at least for me for now.

This probably wont work on a high traffic host, as this is written

quick and dirty in an high level programming language... (perl).

I might write it in C one day :)

Install on Mr. Ubuntu 12.04.1 :

$ apt-get install libnetpacket-perl libiptables-ipv4-ipqueue-perl

$ sudo perl alcanfw.pl --verbose
