About 65 million people took part in the First World War, killing more than 10 million and injuring 20 million.胡钧看见他，急忙站起来，目露奇异之色，正要将打叠好的一番温柔言语来宽慰他，让他安心，就听黎章冷哼道：胡兄弟先请回。1 枪男* * Can you finish it depends on fate * *These parts are Wang Yanzhang's tail (130,000 copper coins), which was changed after a hundred refined outfits were changed. The jade spirit and hole position can be obtained by fighting in the battlefield, while the fourth-level Lantian jade is saved.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.
