Check out:

http://cvs.snort.org/viewcvs.cgi/*checkout*/snort/doc/README.frag3?rev=HEAD&content-type=text/plain

There are a couple of references in the frag3 section of the manual (first
link above) that are worth following. Also, a google search for
"fragmentation attacks" should give you some info.


Cheers,
Justin
