I have a question regarding the 3-way tcp handshake. Where does the fault lies when the sender does not send back an ACK? This is the situation that I am currently getting. We have two sender, A and B.
A --> B [SYN]
B --> A [SYN, ACK]
A --> B No response
Does this mean that A did not get the [SYN, ACK] from the second phase of the handshake? Or did "A" block the third phase? Can someone clarify this for me. As always, thank you for your time on this matter...it is always appreciated.
