What is tcpflow
tcpflow is a program that captures data transmitted as part of TCP connections (flows), and stores the data in a way that is convenient for protocol analysis or debugging. A program like ’tcpdump’ shows a summary of packets seen on the wire, but usually doesn’t store the data that’s actually being transmitted.
