TCPDUMP2XPLOT(1)
NAME
tcpdump2xplot -- converts tcpdump output to xplot input for analysis
SYNOPSIS
tcpdump2xplot [-?] [-c] [-help] [-list[filename]] [-plot[filename]] [-q] [-r] [-s] [-t] [-w]
DESCRIPTION
- tcpdump2xplot takes the output of
- tcpdump -tt -S ...
- and plots it in terms of sequence-number versus time, with other info
displayed (e.g., the TCP window, acks, etc.).
OPTIONS
- -?, -help prints a help message. -c, ``cumulative'', adds all the data
coming from a server. -list[filename] prints the list of generated plot
files to filename. -plot[filename] plots the packets from filename. The
filename may be built out of a hostname and port number, e.g.:
abc.def.com:1234. The default is - fromhost:fromport-tohost:toport.xplot
- where fromhost, fromport, thost, toport are extracted as conversations from the tcpdump data. -q means "quiet" --- no visible output. -r means use relative sequence numbers. -s means break up conversations on TCP syns. -t convert time to decimal number of seconds. -w plots the TCP window.

BUGS
tcpdump2xplot may not deal properly with output from tcpdump that is not
TCP. Either filter to only tcp or be careful.
HISTORY
- The tcpdump2xplot has been contributed by xplot.org users. Thanks to
Garret Wollman for contributing the original tcpdump2xplot.pl script and
thanks to Eric Prud'hommeaux (@ w3.org) for making
<http://www.w3.org/pub/WWW/config/tcpdump2xplot.pl> available, a much
improved version. The one included here is a slightly improved version
of Eric's.
