I was just thinking that a nice addition to iptables would be the
ability to pull in an external file of address:ports to allow/block.
Something like:
iptables -I INPUT -s @fileofbadpeopleips -j DROP
and have it resolve that file into a single rule with multiple matches.
A big OR list of addresses.
Hmm. Time to write Rusty.
While I'm at it, I'll put in the request for a -name flag. Having rules
(some at least) named make modifying that one rule easier.
<run script to update bozo list from apache log>
iptables -D INPUT -name "bozo web list"
iptables -I INPUT -name "bozo web list" -s @bozoweblist -j DROP
Of course, I would also like to see a new target: -j FLOG
It sends the IP address to a userspace app that finds the lat/long of
the moron and sends in a small mob of drunken sailors with an attitude
problem...
