What is "Tcpillust"?

Tcpillust is an X11 based graphical analysis tool for tcp connection. It takes tcpdump file(s) specified at the command line and draws pictures like figures in the ``TCP/IP Illustrated'' series.

Tcpdump files fed to by tcpillust should contain only data for a single TCP connection. If other data are contained in the tcpdump files, tcpillust can't generate results or the results will be inaccurate.

When tcpillust takes a single tcpdump file, it guesses transmit time and receive time on the remote host. When tcpillust takes two tcpdump files, it regards them as tcp-client side file and tcp-server side file, and generates the results from them. If you want precise analysis, you should use two tcpdump files.
