I'd disagree that there's absurdity from Erik. But either way, I added
the var to the BS rules, not Erik. I'm the person to talk to about it.
Erik just proposed sigs, I edited them, approved them and committed
them. It was me 4 days later that removed the var crutch from the sigs
assuming after 2 business days folks would have either seen the 2
announcements on the site and the mailing lists, or seen it in the diff
emails sent to both lists.

That'd be a good thing if ossrc gets rolling. It's not there now, and
may be a while. I'm not willing to suppress very useful rules in the

Ummm.. Why?  Can't you add it? If you need help with vi let me know.  :)

Already been done. Waiting on a response.

I wish the subject would die off here. We added a var. If you don't like
it then don't use those sigs. They're very easy to disable in any rule

if you're pushing rules without reading them and not tailoring the
changes to fit your needs then you're going to have more problems than a
new var.

If your customers (and anyone else for that matter) had a snort crash I
hate to hear that. I don't ever want to drive anyone away from snort or
bleeding snort for any reason. But this is a simple fix. Add the var,
restart. We're talking minutes at the most out of your day. And
hopefully a lesson learned not to trust anything blindly when you're
dealing with your own security.

I do hope folks trust us, but you should still check us. Not just
sometimes, but *every* time. If that doesn't make sense you shouldn't be
in this field.
