SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.

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.
IBM's Price agrees.

Originally, I played on the battlefield for a long time. Who hasn't smelled the blood? Who hasn't seen red brains, piles of intestines, broken arms and legs? Arguably, I should have adapted to this taste long ago. But that was different, It was blood, but it was very, very strong, so strong that those of us who used to smell it could not adapt to it. When I first smelled it, I was surprised. I felt that this smell was by no means emitted by human corpses. Later, I realized that this smell was emitted by the following something similar to the previous dog-like and non-dog-like things. " Zhao Mingkai paused here and probably wrinkled his nose instinctively, as if he had smelled the unforgettable and unpleasant smell of that year.
