NAME

SYNOPSIS

DESCRIPTION

takes tcpdump file(s) specified on the command line and draw pictures like figures in the ``TCP/IP Illustrated'' series.

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

When takes a single tcpdump file, it guesses transmit time and receive time on the remote host. When 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

Specify data packet delay. This value is used to guess transmit time and receive time for data packets on the remote host. When takes two tcpdump files, this value has no effect. 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 takes two tcpdump files, this value has no effect. Set the size and location of the window. Display the usage and exit. Display the Tcpillust version and exit. Be verbose. Generate debugging output to standard output.
