.Sh NAME
.Nm tcpdump2xplot
.Nd converts tcpdump output to xplot input for analysis
.Sh SYNOPSIS
.Nm tcpdump2xplot
.Op Ar -?
.Op Ar -c
.Op Ar -help
.Op Ar -list[filename]
.Op Ar -plot[filename]
.Op Ar -q
.Op Ar -r
.Op Ar -s
.Op Ar -t
.Op Ar -w
.Sh DESCRIPTION
.Nm tcpdump2xplot
takes the output of 
.Dl tcpdump -tt -S ...
and plots it in terms of sequence-number versus time, with other info
displayed (e.g., the TCP window, acks, etc.).
.Sh OPTIONS
.Ar -?,
.Ar -help
prints a help message.
.Ar -c, 
``cumulative'', adds all the data coming from a server.
.Ar -list[filename] 
prints the list of generated plot files to filename.
.Ar -plot[filename]
plots the packets from 
.Ar filename.
The filename may be built out of a hostname and port number, e.g.:
.Pa abc.def.com:1234.  
The default is 
.Dl fromhost:fromport-tohost:toport.xplot
where 
.Ar fromhost,
.Ar fromport,
.Ar thost,
.Ar toport
are extracted as conversations from the 
.Nm tcpdump
data.
.Ar -q 
means "quiet" --- no visible output.
.Ar -r 
means use relative sequence numbers.
.Ar -s 
means break up conversations on TCP syns.
.Ar -t 
convert time to decimal number of seconds.
.Ar -w 
plots the TCP window.
.Sh EXAMPLES 
.Sh SEE ALSO
.Xr tcpdump 1 ,
.Xr xplot.org 1
.Sh BUGS
.Nm tcpdump2xplot
may not deal properly with output from tcpdump that is not TCP.
Either filter to only tcp or be careful.
.Sh HISTORY
The 
.Nm tcpdump2xplot
has been contributed by
.Nm 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.
