If you got multiple nics, the -s = will help you originate the packets from that particular interface using = ip though not name. You need someone at the other end to do the same and then you may have a = complete turnaround path for that moment in time!

Basically so if I am multihomed and I leave one way = and come back through a different circuit it will show both paths. Unfortunaly I could = not find an option with this. Does anyone know of a different version of traceroute or = maybe a different program or an option with traceroute that I do not know of ?
