tcptrace arguments

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 normal output (useful to just see what modules have to say)

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]
-G
create ALL 3 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
only connection N (can use multiple times)
-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 packets
-P
print selected packets
-t
'tick' off the packet numbers as a progress indication
-v
print version information and exit
-w
print various warning messages
-e
extract contents of each TCP stream into a file
-fEXPR
output filtering (see -hfilter)
-u
print minimal UDP information too
-Ofile
dump matched packets to tcpdump file 'file'
-d
whistle while you work (enable debug, use -d -d for more output)
+[v]
reverse the setting of the -[v] flag (for booleans)
