why udp client work when wirshark capture?
- by herzl shemuelian
I have two machine A,B windows 7 os .I connect them end to end
and try run a performance test by using tcpreplay.
step 1) I check conectivity between to point by netcat
In A i run
nc -lvup 5432
when I run on B
nc -u 1.2.3.4 5432
I can send data from B to A
step 2) when in I run tcpreplay in B
tcpreplay -i %0 myudp.pcap
in A I don't recevice any data . when I open wireshark in A then my nc can read data
why?
I check dst mac and dst ip in pcap file they are correct.
is importan udp src mac or src ip for udp how that I open udp server ?
