NAME

       tcptrace - a TCP connection analysis tool

SYNOPSIS

       tcptrace [options] filename

DESCRIPTION

       tcptrace  takes  a tcpdump file specified on the command line (or from standard input) and
       produces a summarization of the connections.

OPTIONS

       Output format options

       -b   brief output format

       -l   long output format

       -r   print rtt statistics (slower for large files)

       -W   report on estimated congestion window (not generally useful)

       -q   no output (if you just want modules output)

       Graphing options

       -T   create throughput graph[s], (average over 10 segments, see -A)

       -R   create rtt sample graph[s]

       -S   create time sequence graph[s]

       -N   create owin graph[s] (_o_utstanding data on _N_etwork)

       -F   create segsize graph[s]

       -G   create ALL graphs

       Output format detail options

       -D   print in decimal

       -X   print in hexadecimal

       -n   don't resolve host or service names (much faster)

       -s   use short names (list "picard.cs.ohiou.edu" as just "picard")

       Connection filtering options

       -iN  ignore connection N (can use multiple times)

       -oN[-M]
            only connection N (or N through M).  Arg can be used many times.   In  N  is  a  file
            rather than a number, read list from file instead.

       -c   ignore non-complete connections (didn't see syn's and fin's)

       -BN  first segment number to analyze (default 1)

       -EN  last segment number to analyze (default last in file)

       Graphing detail options

       -C   produce color plot[s]

       -M   produce monochrome (b/w) plot[s]

       -AN  Average N segments for throughput graphs, default is 10

       -z   zero axis options:

       -z   plot time axis from 0 rather than wall clock time (backward compat)

       -zx  plot time axis from 0 rather than wall clock time

       -zy  plot sequence numbers from 0 (time sequence graphs only)

       -zxy plot both axes from 0

       -y   omit the (yellow) instantaneous throughput points in tput graph

       Misc options

       -Z   dump raw rtt sample times to file[s]

       -p   print all packet contents (can be very long)

       -P   print packet contents for selected connections

       -t   ┬┤tick' off the packet numbers as a progress indication

       -v   print version information and exit

       -w   print various warning messages

       -d   whistle while you work (enable debug, use -d -d for more output)

       -e   extract contents of each TCP stream into file

       -h   print help messages

       -u   print minimal UDP information too

       -Ofile
            dump matched packets to tcpdump file 'file'

FILES

       Dump File Names
       Trailing (unrecognized) arguments are taken to be one or more filenames.  The files can be
       compressed, see compress.h for configuration.  If the dump file name is 'stdin',  then  we
       read from standard input rather than from a file.
