I used raw socket to build a tcp client program on machine A to reproduce tcp 3-way handshake with a simple regular tcp server on machine B
I captured packets on the client host and server host, and got the captured file as below
there are 3 packets, SYN, SYN/ACK, AKC on the client side, the wireshark interace shows that this is a normal tcp 3-way handshake, but on the server side, it shows : tcp port numbers reused, what is wrong with this?
but when I use
I see the tcp connection has been established what is wrong with this? thanks!
