   I had trouble measuring single RTTs, rather than the min, max, and
avg of the RTTs for a whole connection.
   When I use the command : tcptrace -r -l test1.dmp
   I only get the statistics of the RTTs for each connection, for example,
the min, max, and avg. But I need the RTT for each packet (or more
precisely, the RTT for each ACKed packet). Any help?
   Thanks!

P.S. The output of the command : tcptrace -r -l test1.dmp ===>

... ...

     RTT samples: 3
     RTT min: 95.3 ms
     RTT max: 99.6 ms
     RTT avg: 97.3 ms
     RTT stdev: 2.2 ms
... ...
