The principle is that syn messages are first responded to syn_ack by DDOS protection system. With a specific sequence number (recorded as a cookie). The real client returns an ack and the Acknowledge number is cookie+1. The fake client will not respond. In this way, we can know that the clients corresponding to those IP are real and add the real client IP to the white list. The next access passes directly, while other forged syn messages are intercepted. The following is a schematic diagram of protection:?

Since the 1920s, the influx of Western journalists into China has been like crucian carp crossing the river, but as far as the social status at that time is concerned, no one can expect Aban to match it. Aban is naturally competitive and can't compete for emergencies in the front line, but his real advantage lies in his extensive upper-level relations. The top level of the Chinese government and the top level of Japan, the United States, Britain, the Soviet Union and other countries in China are full of his personal friends. At the beginning, the national government wanted to expel him from the country, but later, all four families took him as their guest of honor. Japan attaches more importance to the fact that the top leaders of various factions and departments in civil and military affairs are eager to break through his threshold. The Soviet Union was also interesting. While setting off a wave of criticism of Aban, it sent an ambassador to talk with him in secret and entrusted him with conveying high-level meanings. As for the United States and Britain, it goes without saying. The importance of Aban lies in the fact that his role has completely gone beyond that of a mere reporter. To the U.S. Government, he is an unpaid senior intelligence agent, providing top secret information free of charge, weighing more than any official spy. To the rest of the governments, he is a supernumerary U.S. Diplomat, and his role is often beyond the reach of U.S. Ambassadors. Therefore, between Japan and the United States, between China and the United States, and between the United States and the United States, he has to send messages frequently. As for the infighting among various countries, they should also reveal their secrets to him so that they can be published in the New York Times and confuse each other. For example, before Japan officially joined the Axis, because of the confrontation between the two factions at the highest level, some people secretly told each other the news, which made him get a global super scoop for no reason. All this, of course, depends on the golden signboard of the New York Times and its inexhaustible resources.
