        ....so let me understand this.  My current setup is:

         

        /usr/local/bin/oinkmaster.pl -C
/usr/local/etc/snort/oinkmaster.conf -o /usr/local/etc/snort/rules

        /usr/local/bin/create-sidmap.pl /usr/local/etc/snort/rules >
/usr/local/etc/snort/sid-msg.map

         

        I need to:

        Create separate directories for the two rulesets

        Change the above to reflect:

         

                /usr/local/bin/oinkmaster.pl -C /usr/local/etc/vrt.conf
-o /etc/snort/rules/vrt

                /usr/local/bin/oinkmaster.pl -C /usr/local/etc/et.conf
-o /etc/snort/rules/et

         

                cp /etc/snort/rules/vrt/*.* /etc/snort/rules

                cp /etc/snort/rules/et/*.* /etc/snort/rules

        Create two new oinkmaster conf files, the vrt.conf containing
what's in the attachment in the original post of the 410 rules.

        Modify create-sidmap.pl line 101 to reflect:

         

                next if ($single =~ /^\#/);

         

        Have I missed anything?  Thanks Jason

        ET and VRT are publishing duplicate rules.

         

        Read the "The New Rulesets are Ready!!" thread here

         

        
http://lists.emergingthreats.net/pipermail/emerging-sigs/2010-October/th
read.html

         

        Not sure if you use Oinkmaster but I posted a solution in that
thread.

                I sent this to snort-sigs a few days ago, but it got
moderated into oblivion.  Here's a pruned down one in hopes it will make
it:

                 

                I am seeing the below with grabbing these rulesets:

                A grand total of 409 dup messages are seen even as of
this morning.  Maybe this one will make it through...
