Re: Stable Snort Rules fails?

It sounds like Juan is using one of the rule management tools that has an unfortunate 'feature' in it's default mode.

I forget the name of the tool offhand, and in a quick search i could not find the information I needed, however as I recall there is a rules management tool that will by default uncomment all rules in the downloaded set prior to merging it with the existing set. There's a commandline switch to inhibit this behavior.

I recall this being discussed on-list several months ago, the author of the tool had commented on-list that he wished he had made the "don't uncomment rules" behavior the default.

Errr...  I just grabbed the same file.  That rule is #19, and it's commented
out along with #20.

Usually if a rule is commented out in the rules distro, it was done for a
reason. :)
