I am trying to establish a TCP connection with a server. I added a firewall rule in the server to drop the TCP packets in order to check how the TCP client terminates.
Client retransmits SYN multiple times and will not receive SYN+ACK and finally the client terminates. I could only see SYN retransmissions in the tcpdump and there was no FIN or any indications on how it closed. So, does the client terminate silently without sending out any closure packet in this case?
And how many times a TCP SYN is retransmitted?
