If you look in the gen-msg.map (it's in the distribution, look for it) you will find:

133 || 34 || dcerpc2: Connection-oriented DCE/RPC - Fragment length on non-last fragment less than maximum negotiated fragment transmit size for client

Then if you look in the doc directory (it's in the distribution, look for it) you will find the document that accompanies this event, it is named 133-34.txt. (I thought the gid-sid.txt naming convention might be helpful)

Also, you might want to enable the preprocessor rules, then you might get the classification as well.

Oh, and one more thing, the events, for the fifty-hundred-billionth time, the format is [GID:SID:REV] so the event you have would be GID 133 (look in the gen-msg.map again for the pre-processor that gives the event), SID 34, REVISION 0. -- Nigel Houghton Head Mentalist SF VRT http://vrt-sourcefire.blogspot.com && http://www.snort.org/vrt/ ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
