Tcptrace command

 
NAME
	Tcptrace - analyzes and inspect network packets and generates gnu plots

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 cwin graph[s] (data on _N_etwork)
  -F      create segsize graph[s]
  -G      create ALL graphs
Output format detail options
  -D      print in decimal
  -X      print in hexidecimal
  -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
  -fEXPR  output filtering (see -hfilter)
  -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      perform (minimal) UDP analysis too
  -Ofile  dump matched packets to tcpdump file 'file'
  +[v]    reverse the setting of the -[v] flag (for booleans)
Dump File Names
  Anything else in the arguments is 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
