I think filters/firewalls are useful. I believe every computer should have one.
Firewalls are a patch to broken network application architechture. If your applications would have been properly designed, you would not have the need for firewalls. They are for perimeter defence only anyway.
The important wording here is "every computer should have one"; indicating that it is the host that protects itself. This said, I do agree that properly written operating systems not even need this. One free Unix-clone I happen to run manages to reach this level of properness; so it is definitely possible. -- Måns Nilsson Systems Specialist +46 70 681 7204 KTHNOC MN1334-RIPE We're sysadmins.
