True, but are the scans TO several systems or just one or a few... while 
clearly you can't ignore all the external nameservers which are "scanning" 
you, can you possibly exclude your "internal" systems which are being 
"scanned" from the group of systems which spp_portscan is watching aver, or 
would that simply mean your entire network, and thus disabling spp_portscan
