[Snort-users] detection_filter not working

Hi,

Fatema, I tried it, but it didn't work. Joel gave me a suggestion that
maybe my version of Snort (2.9.8.3) has a bug with detection_filter. After
I finish working with my current project I will upgrade to 2.9.9 version
and check if the problem will be gone.
