Hello,
Sorry about the delay in response. May be you are still curious about
this problem?
tcptrace lists information on RTT samples on connection initiation phase
alone and prints it as "RTT from 3WHS" with the "-lr" options (which could be
partially helpful to you, I guess). But as yet
it can't do RTT stats from connection setup and life phases
separately. But tcptrace seems like *the* person to do this job :-) If you
are fairly conversant with tcptrace code, this should be reasonably easy
to do. I shall see if this can be added in next version of tcptrace.
