'''tcpflow''' is a tool that captures data transmitted as part of TCP connections, and stores the data in a way that is convenient for protocol analysis, keyword searching, etc.

== Overview ==

tcpflow stores all captured data in files that have names of the form
: 128.129.130.131.02345-010.011.012.013.45103
where the contents of the above file would be data transmitted from host ''128.129.131.131'' port ''2345'', to host ''10.11.12.13'' port ''45103''.

== Limitations ==

tcpflow does not understand IP fragments.

 '''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 and debugging. Each TCP flow is stored in its own file. Thus, the typical TCP flow will be stored in two files, one for each direction. tcpflow can also process stored ‘tcpdump’ packet flows.
-tcpflow is similar to ‘tcpdump’, in that both process packets from the wire or from a stored file. But it’s different in that it reconstructs the actual data streams and stores each flow in a separate file for later analysis.
+tcpflow is similar to ‘tcpdump’, in that both process packets from the wire or from a stored file. It's also similar to WireShark, in that both allow analysis of network traffic. But unlike either tcpdump or WireShark, tcpflow reconstructs thousands (or millions) of TCP connections at a time and saves the results in ordinary files, making it easy to analyze the data with conventional tools.
 tcpflow understands sequence numbers and will correctly reconstruct data streams regardless of retransmissions or out-of-order delivery.
 Jeremy Elson developed the first version of tcpflow in 1999 but stopped maintaining it in 2003. In 2006 Simson Garfinkel took over maintenance of the program and added:

 tcpflow is based on the LBL Packet Capture Library (available from LBL) and therefore supports the same rich filtering expressions that programs like ‘tcpdump’ support. It should compile under most popular versions of UNIX; see the INSTALL file for details.
