If an attacker sends a large number of SYN requests with fake source addresses, the server side will consume a lot of resources to handle this semi-connection, and saving traversal will consume a lot of CPU time and memory, not to mention retrying SYN + ACK on IP in this list. The end result is that the server has no time to ignore the normal connection request-denial of service. If you look at the SYN_RECV status on the server with the netstat-an command, you can see that there are a large number of connection states that are "SYN_RECEIVED"

Sun Tzu said: The art of war is of vital importance to the State. It is a matter of life and death, a road either to safety or to ruin. Hence it is a subject of inquiry which can on no account be neglected. Therefore, the classics are based on five (things), and the schools are based on their plans, and their feelings are asked: one is Tao, the other is heaven, the third is earth, the fourth is generals, and the fifth is law. The Tao makes the people and the people agree, so they can (to) die with it, and they can (to) live with it, instead of (fear of danger) (paradox). Heaven signifies night and day, cold and heat, times and seasons. Earth comprises distances, great and small; danger and security; open ground and narrow passes; the chances of life and death. The Commander stands for the virtues of wisdom, sincerely, benevolence, courage and strictness. Dharma, music system, official way, the main use also. All these five will be heard, those who know will win, and those who do not know will be defeated.

The policy pattern defines a series of algorithms and encapsulates each algorithm so that they can be replaced with each other, and the changes in the algorithms will not affect the customers who use the algorithms. It is necessary to design an interface to provide a unified method for a series of implementation classes. Multiple implementation classes implement the interface, design an abstract class (optional, belonging to auxiliary class), and provide auxiliary functions. The diagram is as follows:

"No one in position 149 was completely unstung, I am no exception, He got several times during the fight, But I'm lucky, None of them stung the key parts, Two big flying wasps stung me in this area of my chest. Luckily there was a bullet bag hanging on it, The bullet bag was stuffed with four shuttles (note: the shuttle here refers to the magazine of an automatic rifle). Four shuttles covered the whole chest, So it blocked the two poison needles directly, No matter how severe the poison needle is, of course it cannot penetrate the shuttle. Just pierced the canvas on the bullet bag, It was hung on it, but although it could not be tied through the shuttle, it could still pass through the slightly thinner metal, because I had been hit several times in my head. When the battle was completely over, I had five poisonous needles on my head, each of which was the front tip already stuck in and the back half was exposed. I was wearing a helmet at that time! Even helmets can be tied up. No wonder several comrades with cloth hats have their skulls nailed through.
