Hopefully the barnyard folks will see this thread and comment on their code.

It looks like there is a lot of code reuse between barnyard2 and snort. Decode.c and spo_database.c are used in both and the versions appear to be very similar. Although the unified2 output is correct, the problem then propagates into barnyard. I still get an invalid pcap from base. Thanks to both of you for the fast response.
I see tha the main issue is the way base reconstruct a pcap file from whats is logged. This being said, there is not mutch we can do for now to make this work since theses pieces of codes (spo_databases) that uses the ACID schema haven't changed since nearly a decade. A simple and easy solution would be to hex the packet payload and log it directly and when the process is ready to make a pcap for selected event, it only have to wrap the hexed payload to generate the pcap file. This is probably something that will come along in a new proposed schema but meanwhile i do not see any simple fix since for now barnyard2 spo_database and the ACID schema will probably stay like they are until they are depricated in barnyard2. -elz ------------------------------------------------------------------------------ uberSVN's rich system and user administration capabilities and model configuration take the hassle out of deploying and managing Subversion and the tools developers use with it.
