Why? It's a home computer, it doesn't need any firewall or host-based
packet filter.

are you being cynical?

[compton ~]$ netstat -tuan
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 192.168.14.12:3228 198.18.97.142:119 ESTABLISHED
[compton ~]$

The _only_ thing "open" on this system is a connection to the news server.
As there is nothing else open, there is nothing to exploit - thus there is
no absolute _need_ for a firewall. ("netstat" is a UNIX command - windoze
has a similar command, but uses different syntax. Try "netstat /ano" for
the XP imitation.)

Most people "need" a firewall because they have no idea what their computer
is running - and by default windoze comes with a lot of stuff enabled because
microsoft thinks it may be useful to a few, and that no one knows or wants to
know how to enable it. Thus, it's available to be exploited by default. If
people learned how to disable the garbage, there wouldn't be a need for a
personal firewall, anti-virus, anti-spyware, and the rest of that mess.
Contrary to what you may believe, there isn't a "Mal-ware Fairy" that comes
around and installs bad stuff on your computer. It gets installed by the user
who has no idea what they are doing.
