Interesting. I'll look at that in detail tonight and see if it does what I want. One of the features I'm really looking for is some kind of notification, like "program XYZ wants to connect to the internet - allow/deny?". Programs like this are pretty annoying when you first install them, but once they've run for a while, they can be damned useful in identifying things that you didn't think were accessing the net, but are.

I'm not aware of any Linux software that does the pop-up thingy.

Typically you would set up your rules then monitor your log files while trying out each program that you want to allow access. Any DENY or BLOCK statement you see means you missed something.

Once you have everything allowed that you want to allow you shouldn't have to fool around with your firewall rules any more.

Something like KSystemLog (KDE) or System Log (Gnome) will do the job.
