(We are trying to see how long the system waits before a SYN gets retransmitted.) When a SYN is sent, a keepalive timer is set with using the TCPTV_KEEPALIVEINTVL = 75hz (??ms - escapes me at the moment). So an ack must be received in this time frame??? This isnot the usual dynamic tretransmission timmer which might make sense for SYN packts. It seems like a retransmission timer should be set?? That's why I'm posing the question.
