[Snort-devel] IP Blacklisting for Snort

Hi everyone,

I wrote a patch for Snort that implements IP blacklisting as a preprocessor in Snort over this past weekend. We talked about this last week on the mailing list in regards to trying to implement blacklisting using regular Snort rules and how well that doesn't work. :)

This code has been tested against Snort only. I've tested builds on OS X, Ubuntu and Fedora so far. It requires libdnet (or dumbnet-dev for those of you on Debian-based distros) to build properly. Check the README file that comes with it for instructions on patching it into your codebase. It supports inline blocking and alerting but not Flexresp-style TCP reset session shootdowns.

Have a look and let me know what features you'd like or bugs you find.

This code is purely EXPERIMENTAL, this is just me spending some of my spare time doing a fun coding project so if your machine sprouts legs and refuses to work until it receives part of the TARP bailout it's not my fault.
