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.
