Barnyard is a critical tool for the parsing of Snort's unified binary files, processing and on-forwarding to a variety of output plugins. Unfortunately it has not seen an updated in over 4 years and is not going to be maintained by the original developers. With the new version of the unified format (ie. unified2) arriving we need something to bridge this gap.

To quote directly from the Snort FAQ:

"Barnyard is an output system for Snort. Snort creates a special binary output format called unified. Barnyard reads this file, and then resends the data to a database backend. Unlike the database output plug-in, Barnyard is aware of a failure to send the alert to the database, and it stops sending alerts. It is also aware when the database can accept connections again and will start sending the alerts again."

The SXL team love barnyard. So much so that we want it to stay and have been tinkering around with the code to give it a breath of new life. Here is what we have achieved to far for this reinvigorated code base:

  • Parsing of the new unified2 log files.
  • Maintaining majority of the command syntax of barnyard.
  • Addressed all associated bug reports and feature requests arising since barnyard-0.2.0.
  • Completely rewritten code based on the GPLv2 Snort making it entirely GPLv2.

This is an effort to fuse the awesome work of Snort and the original concept of barnyard giving it a fresh update along the way. We've come a long way so far and have a very stable build that we've integrated into our NSMnow framework. If you have any feature requests, bugs or gripes then send them our way.
