RE: format of unified log file?

The way that I figured it out was to look at the spo_unified.c, and parse out the various struct's within that. Yes, it's C, but it's not particularly complicated to logically parse out the structure. Look at these structures: UnifiedLogFileHeader, UnifiedLog, Event, SnortPktHeader. Basically, the log file starts with a UnifiedLogFileHeader, and then has a bunch of UnifiedLog's, which consist of an Event struct, 32 bits of flags, and a SnortPktHeader struct. (and then, I believe, caplen worth of actual payload data), followed by a new UnifiedLog. -Joe

I apologize if this has been covered before, but I am looking to write a utility to parse the binary unified log files produced by snort. According to the snort Users Guide the binary log file format is described in the spo_unified.h header file, however when I look at that file I don't see anything resembling a file format desc (in fact the file has < 30 including comments). Am I looking in the wrong place (src/output-plugins directory of the 2.3.0 distribution). Would I find the description in an older revision of this file (appears that I'm looking at v1.9), or where else might I find the documentation on how that file is layed out? I might be able to figure it out by looking at the input processors for mudpit and/or barnyard, but my C is terribly rusty so I'd prefer to have some documentation. If anyone can point me in the right direction it'd be greatly appreciated. thanx, </rob> --------------------------------------------------- Robert M.
