Hi all- Here's the problem I'm having: I have a client site that has two physical connections from its ATM switch that connect to two different providers. The ATM switch uses both connections all the time (not set up as a failover.) The ATM switch at the site will not let me mirror the ports so I can't sniff there... and after the two providers, the connection is too fast for my equipment. I am using Snort 2.3.2 on PowerEdge 1750's. If I place a sniffer at both provider A and provider B, is there a way I can reassemble the traffic so I can see complete sessions? The two providers are on different sides of town.
Chris, If your using Linux, try channel bonding both interfaces into one that you run snort against.
