# 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.

# stateful inspection directive
# no arguments loads the defaults (timeout 30, memcap 8MB)
# options (options are comma delimited):
#   keepstats [machine] - keep session statistics, add "machine" to get them
in
#                         a flat format for machine reading
#   noinspect - turn off stateful inspection only
#   noalerts - turn off alerts from the stateful inspector
#   timeout [number] - set the session timeout counter to [number] seconds,
#                      default is 30 seconds
#   memcap [number] - limit stream4 memory usage to [number] bytes

preprocessor stream4 noalerts
                     ^^^^^^^^--- This should do the trick.

Or is there any way to disable that particular type of alert from the
stream4 preprocessor?
