TCPDUMP2XPLOT(1)	     General Commands Manual		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 dis-
     played (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 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/con-
     fig/tcpdump2xplot.pl> available, a much improved version.	The one included
     here is a slightly improved version of Eric's.
