[Snort-users] Why Gibson scans don't register?

The site you're talking about is http://grc.com

He does a scan of known/common services/ports only and I think he executes
his scan kinda slow. It may fall within the threshold set in the scan
preprocessor assuming you're using it. If you're not using it, then that
would also explain the lack of alerts. If you tested the shields you'd get a
NetBIOS probe. I think there's a rule for that but it would trigger like
crazy anyway. NetBIOS probes are for windows like.... farts are for people.
