TCP is a reliable protocol, and messages will be retransmitted at this time. The default number of retries is 5. The interval time of retries is doubled from 1s to 1s + 2s + 4s + 8s + 16s = 31s respectively. After the fifth time is sent out, it will take 32s to know that the fifth time has timed out, so the total is 31 + 32=63s.Qinglan looked everywhere for health and apologized to him, but told her calmly and healthily to talk about them after Yishang's wedding.

Therefore, if C wants to forge the packet from A to B, it should fill in the above-mentioned IP header and TCP header with the source IP, source port, target IP and target port. Here B is the server, IP and port are open, A is the target we want to attack, IP certainly knows, but the source port of A is not clear, because it may be randomly generated by A. Of course, if we can find out the rule of generating source port for common OS such as Windows and Linux, we can still do it. In addition, we can step on the connection port of Car A through a large number of controlled hosts.
