Sadly there are few who know about the excellent continuation of the original and stale but popular Barnyard code.
The great guys who manage Securix Live and NSM Now! Opensource projects have taken on updating and improving on the original Barnyard code.
Some of the new features are bug fixes, Unified2 support, support of Snort 18.104.22.168 and a slew of output plugins (mysql,postgres,syslog,cef,tcpdump,prelude,etc)
If you are a user of the old Barnyard code for high performance Snort log processing then I very highly recommend you give Barnyard2 a spin...
