[Sheflug] Firewalls and port scanners

[Craig Andrews <nospam [at] fishbot.org.uk>]

Hi all,

I have been messing around with ipchains to make a simple firewall for
internet use. I have used shields-up! at www.grc.com, but I vaguely
remember some talk about alternative, more generic (shields up is
intended to test windows machines primarily. It has a lot of NetBIOS stuff
there) port scanners.

As I do not wish to have any publicly open ports at this time, would
blanket-rejecting anything on ppp-in be acceptable?

Finally, I have been messing with gfcc, a Gnome/GTK+ firewall config
program which has several templates and can output shell scripts in an
instant. It makes the whole process much more pleasant.

Cheers,

Craig Andrews

Life would be so much easier if we 
could just look at the source code.
