During the establishment of a tcp connection, If the server returns syn and ack messages, The client does not confirm it for some reason. This is because the server needs to retransmit the syn + ack message and wait for the client's confirmation message until the tcp connection timeout. This state of waiting for the client to confirm the connection is usually called a half-open connection. The half-open connection will be kept in the connection table of the server until the connection is disconnected.

How should we defend against this attack? First of all, as users, we try our best to download APP from regular channels and surf the Internet in a civilized manner, and try our best not to make broilers. Secondly, as a service manufacturer, when the server is attacked by DDoS, we try our best to improve the processing capacity of the server. When the processing capacity of our server is greater than that of the attacker, these attacks are nothing to the server. Finally, under normal circumstances, the processing capacity of our server is generally lower than that of the attacker. In view of this situation, there are currently the following methods: 1. Violent methods, such as setting an access frequency threshold, and rejecting when the number of accesses per IP unit time exceeds this threshold; For a certain service, if the instantaneous request is too large, choose to directly refuse to ensure the normal operation of other services; This method may result in normal users not being able to use it. 2. Verification code. In order to prevent normal users from being injured by exposure methods, at present, service providers will send verification codes to "users" when receiving a large number of requests. If it is a real user, it will input verification codes, but if it is a broiler, it will not. Through this method, the real user and the broiler will be distinguished.
The host is the most important. People input data to the host computer through keyboard, mouse and other input devices. After data processing by the host computer, the results are output to us through output devices such as displays and printers. The main components of the host include: memory, hard disk, motherboard, graphics card, sound card, optical drive, floppy drive, etc. Now many graphics card-like components can be integrated into the motherboard. CPU is also called central processing unit. CPU is the abbreviation of Central Processing Unit in English. As important as people's brains. It directs and dispatches all the work of the computer. Usually we refer to the CPU model when we say Ben 2, Ben 3 and Ben 4.

范增咳嗽几声道：真正的事情还是要靠我们自己，那些墙头草诸侯们起不到多大的作用。
5-3 attacks 7-2 end up together, because although the 5-3 monster has a higher life value, the opponent's attack power exceeds the 5-3 life value (3 points), so 5-3 will be destroyed. On the other hand, 7-2 has only 2 blood, so the 5-attack will destroy him.
