------- Comment #4 from evensky at dancer.ca.sandia.gov  2008-06-04 03:17 -------
Created an attachment (id=145)
 --> (http://www.nsnam.org/bugzilla/attachment.cgi?id=145&action=view)
simple two way tcp test program using what I guess is the current API.

I can't tell where the bug is in my code or ns-3-dev, the docs for Socket seems
to have disappeared from doxygen generated web pages. I think I'm using the API
correctly using the force (aka looking at the source), but I'm not sure. I
would like to see some sort of bi-direction test added to ns-3 distro so that
this sort of functionality gets tested.

This program should send bytes both ways, but it doesn't it only send bytes the
forward direction.

Output:

evensky at waltz$ ./tcp-tester 600 700

(size=536)|ns3::SocketRxAddressTag [0-536] address=00-00-00
TalkerApp::HandleRead(0x6333e0): Server
  64 bytes from 10.1.0.1 [02-06-0a:01:00:01:01:c0]  Payload
(size=64)|ns3::SocketRxAddressTag [0-64] address=00-00-00

What does the 02-06 part of the mac addr mean? What is the address tag in the
packet used for?

Thanks,
