TCPDUMP2XPLOT(1)       DragonFly 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
     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.


EXAMPLES


SEE ALSO

     tcpdump(1), xplot(1)


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/config/tcpdump2xplot.pl> available, a much
     improved version.  The one included here is a slightly improved version
     of Eric's.
