TCPILLUST(1)

NAME
tcpillust - a graphical TCP connection analysis tool

SYNOPSIS
tcpillust [-Vhv] [-d data packets delay] [-s syn packets delay] [-g geometry] file [file]

DESCRIPTION
tcpillust takes tcpdump file(s) specified on the command line and draw pictures like figures in the ``TCP/IP Illustrated'' series. Tcpdump files used 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 generate the results from them. If you want precise analysis, you should use two tcpdump files.

Options

-d data packets delay
    Specify data packet delay. This value is used to guess transmit time and receive time for data packets on the remote host. When tcpillust takes two tcpdump files, this value has no effect.

-s SYN packets delay
    Specify SYN or ACK packet delay. This value is used to guess transmit time and receive time for packets which do not contain data(like SYN packets) on the remote host. When tcpillust takes two tcpdump files, this value has no effect.

-g geometry
    Set the size and location of the window.

-h  Display the usage and exit.

-v  Display the Tcpillust version and exit.

-V  Be verbose. Generate debugging output to standard output.
