Scott, I'm not sure. I based the portscan2 comment on a number of other posts I've seen claiming that it does work, but I haven't used portscan2 since I upgraded to snort-2.0. I do know for sure that flow-portscan will log into ACID if you set the pktkludge output option, but it's such a nasty mess formatwise, that I eventually disabled the portscan messages altogether. I've meant to go back and use portscan2, but never gotten around to actually digging out the required configuration options and reenabling it. One thing to check, though; Are you using 'log' rather than 'alert' on your database output plugin configuration line? The portscan2 plugin logs to the 'log' facility rather than to the 'alert' facility.

I didn't receive any alerts in acid, however, I did receive many entries in /var/log/snort/portscan2.log. Have I skipped a step here and left something out? -Scott ----- Original Message ----- From: "McCash, John" <John.McCash () andrew com> To: "Scott Elgram" <SElgram () verifpoint com>; <snort-users () lists sourceforge net>; <erek () snort org> Sent: Monday, August 16, 2004 12:10 PM Subject: RE: [Snort-users] Snort-2.1.3 Portscan Scott, This needs to go in the FAQ. Because Roman hasn't updated ACID in ages, it lacks support for flow-portscan. To get ACID to properly recognize portscans, you need to go back to portscan2, which is still implemented in the code, but no longer listed in the default conf file. There are a number of articles in the snort-users mailinglist archives that address this, including http://marc.theaimsgroup.com/?l=snort-users&m=109044048107572&w=2. On a side note, Roman is purportedly working on a major update for ACID in conjunction with other work, but it's apparently going slow. We're hoping for something in the Q1 '05' timeframe.

I have it all up and running just fine right now except for one thing. I can't seem to get anything to register in the port scan traffic section of Acid. I have looked through my Snort.conf for anything and found the flow-portscan preprocessor. I uncommented it and configured it as follows: -------------------------------------------------------- preprocessor flow-portscan: \ unique-memcap 5000000 \ unique-rows 50000 \ server-watchnet [192.168.0.0/24] \ server-learning-time 300 \ server-scanner-limit 50 \ alert-mode once \ output-mode msg \ tcp-penalties on -------------------------------------------------------- Even with this configuration I still can't seem to get anything to register in that particular section. I am using superscan and scanning various IP's on the network SNORT is watching. Have I configured this wrong maybe?
