... Or by spoofing the source IP address in the SYN, it makes the server send the SYN-ACK to the falsified IP address, and thus never receive the ACK. In both cases, the server will wait for the acknowledgement for some time, as simple network congestion could also be the cause of the missing ACK. In su ...
