This is in response to all the iptables + strings mails, talking about
blocking such things as nimda and codered, etc.

The following link has two things. A tutorial on getting strings matching to
work (it is NOT enabled by default), and within that article there is a link
to my rejectstrings shell script which does exactly what you people want.

Enjoy, and pass the article around.
