Flowbits esentially allow you to set flags and check for them.   For
instance, you could set a flag on for every nimda attempt, and then add
a check for that flag in a rule that matches the response from a
vulnerable server.  Thus giving you true notification of something bad.
I believe someone posted to the -dev or -users group with the specific
syntax recently.

hi.
I'm a newcomer in this mailing-list and I have recently upgraded my
Snort. There are several new keywords in rule files, which are not
explained in Snort manual. What is meaning of flowbits?
Thanks for your time and attention.
