A combination of ignorehosts and ignoreports-from has cut down on my false positives considerably. Thanks!

It wasn't clear to me how I might go about filing an enhancement request. Can someone point me in the right direction?

If not, other than: preprocessor portscan2-ignorehosts: preprocessor portscan2-ignoreports-to:
  preprocessor portscan2-ignoreports-from:

and preprocessor portscan-ignorehosts:
I'm not aware of any other mechanism that meets your needs.  Well, except
BPF filter on the command line. Cheers!

Subject: [Snort-users] portscan target filter ?



Hi There,

I would like to filter out a list of port scan target ip's as well as source ip's. I don't see an easy way to do this with either of the two portscan preprocessors. Has anyone come up with a way to do this? I'm running 2.0.0.

thanks for any help,

-charles
