tcpflow: tcpflow (TCP/IP session demultiplexer) tcpflow: tcpflow: tcpflow is a program that captures data transmitted as part of TCP tcpflow: connections (flows), and stores the data in a way that is convenient tcpflow: for protocol analysis or debugging. Each TCP flow is stored in its tcpflow: own file. Thus, the typical TCP flow will be stored in two files, one tcpflow: for each direction. tcpflow can also process stored ‘tcpdump’ packet tcpflow: flows. tcpflow: tcpflow: tcpflow:
