Not sure when logging of reassembled packets was removed -- maybe 2.2 or even earlier.... Its been a good while, for sure. ;) Snort is only designed to write out the original packets in pcap form -- and not the reassembled packet or arbitrary normalized data that was never actually seen on the wire. This keeps the pcap log as a record of actual on-wire traffic. The unified2 extra data record type was created for the purpose of logging relevant data from the event so it would be useful to analysts. For example, Snort can log the normalized HTTP URI, SMTP filenames, email recipients, etc. Almost sounds like using unified2 logging might better serve your purpose...

The only output method that supports this (differently mind you) is unified2. If you log to unified2 it will log the event and the packet(s) that made up the event. In your case these should be the packets that created the reassembled pseudo packet.Interesting. Do you know of a particular date this might have happened around? I'd like to go dig into CVS and maybe re-integrate the code and try it out. Could've been a problem with it initially that forced the removal. I haven't played with unified2 that much. I typically just log to straight libpcap files and analyze them in WireShark.
