In earlier Win32 versions of Snort (prior to 2.0 rc3 or so?!), the '-s' parameter (at least in Win32) was somewhat busted, but I understand that it's been fixed. I also seem to remember posts on this list about '-s' being busted in non-Win32 platforms, but again, I think it's now fixed. As a FYI: I patched my 1.8.7 and 1.9.0 versions so that '-s' didn't override the output plugin statements in snort.conf. So, are you still getting duplicate (dual) alerts in ACID and syslog or is everything straight now? - Christopher -----Original Message----- From: David Markle [mailto:davidmarkle () comcast net] Sent: Monday, April 14, 2003 6:57 PM To: L.

I was under the impression that the command line argument for syslog overrides the snort.conf file settings, therefore strayed from that approach. Although working you your suggestion, I (had) the following: output alert_syslog: LOG_local1 LOG_ALERT output database: alert, mysql, user=root password=mypwd dbname=snort host=localhost In my local syslog.conf, I have remote logging to another host from the local1 facility. I bit convoluted, but functional. -----Original Message----- From: L.

I run two Snort sensors in a Win32 environment. Both sensors "log" to MySQL and also alert to two separate end-points: syslog and a text file. My output statements in snort.conf look like: output alert_fast: alert.ids output database: log, mysql, host=somehost port=3306 dbname=snortdb user=snort password=somepassword sensor_name=sensor1 encoding=hex detail=Full output alert_syslog: LOG_AUTHPRIV LOG_ALERT My syslog server is a remote server, and I specify the address of that server using the '-s ipaddr:514' command line parameter for Snort. I get no duplicate alerts. So what are the exact output statements you're using in snort.conf, and what is the command line you're using to start Snort? - Christopher -----Original Message----- From: David Markle [mailto:davidmarkle () comcast net] Sent: Sunday, April 13, 2003 9:44 PM To: snort-users Subject: [Snort-users] Dual Alerts ? I would really like to have TWO working OUTPUT PLUGINS: (Databases and Syslog). From what I have determined, two Syslog FACILITIES are used (auth.notice and daemon.notice). The auth.notice (which is configurable in the snort.conf) is used for alerts and daemon.notice is used for snort start/stop etc. Both output plugins are important because I want Syslog to a remote host and the database output plug for ACID. The problem is, I'm getting dual alerts in both ACID and Syslog and do not know why, (other than two output plug entries in the .conf file - duh). Can't the output plugs fork the data independently ? Is this a limitation of the product or my knowledge ?? Thanks in advance.
