Re: How to Ignore certain alerts

["Daniel Qian" <daniel.qian () supracanada com>]

I am also on command line for the snort part where the alerts are output to unified2 format before barnyard2 parses 
them into Mysql database for Base to display.

By the way, is there a Linux version of Sourcefire interface?

  Maybe someone that uses the BASE interface can answer for you.  I haven't used anything but the command line and 
Sourcefire's interface for about 4 years.

      You should place the suppressions in the threshold.conf file.  Make sure that the file is also uncommented in the 
snort.conf file.  (It's at the very bottom of the stock file)

          Check out "suppression" in the Snort manual.

            I am having nearly 10000 Microsoft SQL server related alerts produced by
            Snort for our /23 network block. But most of our systems are not even
            Microsoft. I am trying to make Snort send these alerts for only a couple
            servers. so I have tried putting

            var SQL_SERVERS [x.x.x.x/32,y.y.y.y/32]

            in snort.conf but it doesnt do anything for me. What is the best approach to
            achieve that result?
