tcpflow understands sequence numbers and will correctly reconstruct data streams regardless of retransmissions or out-of-order delivery. However, it currently does not understand IP fragments; flows containing IP fragments will not be recorded properly.
tcpflow is based on the LBL Packet Capture Library and therefore supports the same rich filtering expressions that programs like 'tcpdump' support. tcpflow can also rebuild flows from data captured with 'tcpdump -w'.

Version 0.20 (February 26, 2001): * A bug was fixed that caused out-of-order reassembly to generate seemingly very large files on some systems (specifically, those that support fgetpos/fsetpos). * Bug fixed that caused the interface to be left in promiscuous mode after tcpflow terminated * The -r option was added, contributed by Jose M. Alcaide <firstname.lastname@example.org> * We now distribute tcpflow R more»
