[Snort-users] Portscan preprocessors

I've been running Snort with Acid for awhile now, and everything seems
to be working properly, except detection of portscans.  I'm using Snort
2.0 on RH8, and I'm logging to a MySQL database.  I tried enabling the
portscan preprocessor in the snort.conf file:  "preprocessor portscan:
$HOME_NET 4 3 /var/log/portscan.log".  I ran a few portscans to test the
preprocessor, but I didn't see anything happening in the ACID console,
though the scans appear in the /var/log/portscan.log file.


  Next I tried disabling this preprocessor, and enabling the
conversation preprocessor: "preprocessor conversation:
allowed_ip_protocols all, timeout 60, max_conversations 3000", as well
as the portscan2 preprocessor: "preprocessor portscan2: scanners_max
256, targets_max 1024, target_limit 5, port_limit 20, timeout 60".
After restarting snort, and running a few portscans, I'm still not
seeing anything in the ACID console.  Is there a parameter I'm missing
to get snort to log these portscans into the MySQL database?


Any help is appreciated,


Mike F.
