If you do use those tools, beware of Snort's stream4 preprocessor,
which does not log an alert until a complete three-way handshake has
completed. This eliminates noise from snot, stick, and other
variants. You all may also want to check out IDS Informer. This is a
software package designed to create a large number of alerts. It
actually simulates the victim host and completes the three-way
handshake. It is commercial and is available from Blade Software
(http://www.bladesoftware.net/prod_ids.html)

Disabling/commenting out stream4 should do the trick.. I'm sure
others may have a different method but this does seem to work for me
when needing to light Snort up.


# stream4: stateful inspection/stream reassembly for Snort

# Use in concert with the -z [all|est] command line switch to defeat
stick/snot
# against TCP rules. Also performs full TCP stream reassembly,
stateful
# inspection of TCP streams, etc. Can statefully detect various
portscan
# types, fingerprinting, ECN, etc.
