How do I get the value for gen_id, sig_id from the Base output to put in threshold.conf file?

  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?

        Two links about the alerts copied from Barnyard2:
