Re: [sonrt-user]About rule options

[Mayur Patil <ram.nath241089 () gmail com>]

Hello Russ Sir,

     I am able to implement text rules with above said options but my
problem is *"Parsing Rules from the Rule generator "* because I

     want to generate the shared object rules.
http://labs.snort.org/cgi-bin/sorules.cgi

     I want to use count, seconds. Whenever I use detection_filter in a
rule, I am getting error while parsing rules from rule generator

     "no valid rules for generation".

      *So is there any option present which I can parse from rule generator
with attributes count,seconds to generate shared

       object rules??*

      Seeking for guidance,

      Thanks !!

**Cheers,
**Mayur*.
