IIRC this is the the FAQ or the manual

var SPECIFIC_PORT 21
include port_list.rules

var SPECIFIC_PORT 110
include port_list.rules

um, false. The second variable definition would override the first, which would leave you with the equivalent of:
alert tcp any 110 -> any any blah blah
which is not what you want.

you can't do a list of ports, the best you can do is something like
---snort.conf----
var SPECIFIC_PORT 21
var SPECIFIC_PORT 110
then in your rule
alert tcp any $SPECIFIC_PORT -> any any blah blah.

Hello,
How can i define a list of ports? eg. 25,110 doesn't work... Now
i know snort can do
port ranging, but how about a specific list of ports only.
please help..thanks
