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.
