I used Idswakeup to test these rules and none of alerts are firing. In snort forum, there was one thread related to this type of trouble with 2.6 version. I tested with -k none options and it didn't help me out.IDSWakeup is stateless. Snort 2.8 probably ignores the out-of-state packets it is producing. Stefano
Ftester on the other hand is stateful: http://dev.inversepath.com/trac/ftester but it's kinda old-fashioned now, it's waiting for a decent rewrite. The concept is still valid though. Cheers
