pseudo:
in Debian Etch it seems Firefox is a "transition of Iceweasel"..whatever that means..
in Debian Sarge the package is definitly named firefox...I guess it's a copyright issue or something like that.

well, if you use the box as simply desktop system a firewall is not really necessary, but imo a Linux user should know how to setup/use one because you don't have this great opportunity in Windows (at least not in such an easy way). I recommend not to use graphical firewall apps, the best way is the good old shell:
to view your firewall rules:
as you can see there you have 3 so-called chains: INPUT, FORWARD and OUTPUT.
you can set different POLICIES for each chain: ACCEPT or DROP
ACCEPT means everything is allowed if it is not forbidden by a rule, DROP means everything is blocked if it is not allowed by a rule.
let's create a rule which drops all ICMP traffic (ping for example):
Code: Select all
iptables -I INPUT - p icmp -j DROP
or another example, let's drop all requests to port 3306:
Code: Select all
iptables -I INPUT -p tcp --dport 3306 -j DROP
it might look a little confusing at the beginning, but when you have tested a little you will be able to use the basic stuff soon...
here are some other basic commands which will be useful:
this flushes all rules
if you want your firewall rules to be loaded automatically on bootup you need to save them first:
when done the rules will be read from the file at when booting, you can also do it manually by
there are so many possibilities that I could just give a first look, here's a nice reference I use too:

have fun, if you have further questions about firewalls just ask..
