This chapter Arguments Quick Reference (QR), explains briefly the options supported by tcptrace .
Basic Arguments
The following options are first read from the file $HOME/.tcptracerc (if it exists), and then from the environment variable TCPTRACEOPTS (if it exists), and finally from the command line.
All the boolean options (options that do not take in an argument along with it) can be given with a ``+'' prefix that has the effect of negating the option. For example, you may give a ``+l'' to not print in the long output format. This can be useful if you store the options you always want tcptrace to use in the $HOME/.tcptracerc file or the TCPTRACEOPTS environment variable but want to turn-off an option for this invocation of tcptrace from command line.
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] -L create time line 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. If 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 Extended boolean options (unambiguous prefixes also work) --showsacks show SACK blocks on time sequence
