hi people 

does anybody know of a s/w or a program which will
send packets and recieve packets and also note down
the time 
at which the packet is sent and time at which the
acknowledgement for that packet is received the
program thus should work in timestamp fashion also
when we talk of packets it needs to be using tcp not
udp ( otherwise i would have used ping) so basically
any service like ping is required here so as to know
the round trip time 
of the packet / data .


                           thanks in advance 

                                        nikhil
