Hi
I am a Snort user. I used the latest version 2.3.3 and found the rule 499 is not able to detect the ping of death attaks in the 1998 DARPA training data, whose link is :
http://www.ll.mit.edu/IST/ideval/data/1998/training/week6/thursday/tcpdump.gz
the labeled information is
http://www.ll.mit.edu/IST/ideval/data/1998/training/week6/thursday/tcpdump.list.gz


I know rule 499 is supposed to detect such kind of attacks. I even tried various values of 'dsize' in the rule. It seems the rule could not work as expected. I cannot explain the results. So I report my issue and hope you can check it. Thanks very much for your attention.

Regards!
