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.
