OT: Centos 6 question

[Mauricio Tavares]

I wrote a shell script that is called by the network interface when it
comes up. What it does is first wipe the old firewall and then starts
populating it; it makes it much easier to set it up and try it out.
Among other things, I can add comments and use variables all over the
place.
