Hi all, please find enclosed my contribution that allows snort to be activated over NetFlow. Basically snort can now act as a NetFlow v5 collector (add -5 <port> to tell snort to wait incoming flows on the <port> [note that -i has no effect if -5 is specified]) and run the signatures over the incoming flows. The main difference between runnins snort over NetFlow with respect to pcap is that with NetFlow you have no payload access so basically all the payload signatures are not activated. So you can detect a portscan but you cannot detect a SSH exploit.
