Info

tcpflow addresses important “real-world” capture problems.When we capture in the real-world, we see:• 1-sided captures (from asymmetric routing)• Missing packets (no SYN)• Duplicated packets• Out-of-order delivery• Hostile packetstcpflow handles these situations.24
tcpflow understands packets so you don’t have to.We think of TCP as a stream-based protocol:HTTP Request“GET /hello.txt HTTP/1.1”HTTP responseHTTP headersHTML contentBut connections are made up of packets:1SYN :80:58221 ACK234SYN/ACK :80“GET /hello.txt HTTP/1.1”DATA :80TCP 3 wayhandshake:58221resp5:58221“Hello World!”FIN67FIN :8025
