In addition to solving the port problem of A, the serial number problem also needs to be paid attention to. The serial number corresponds to the sliding window. The fake TCP packet needs to be filled with the serial number. If the value of the serial number is not in the sliding window of B when it is sent to B before A, B will actively discard it. So we need to find the serial number that can fall into the sliding window between AB at that time. This can be solved violently, because the length of a sequence is 32 bits, and the value range is 0-4294967296. If the window size is like 65535 under Windows I caught in the above figure, I only need to divide, and I know that at most I only need to send 65537 (4294967296/65535=65537) packets to have a sequence number fall into the sliding window. The desired value can be calculated quickly by exhaustion on multiple control hosts.　　马田为求早日脱身，遂制造机会，让警方尽快把尊逮捕归案，瓦解黑帮，可是警方以证据不足为由释放了尊，致使马田的处境变得岌岌可危。Home Before Dark is a new Apple Original about a nine-year-old journalist who helps solve a murder.
