Facing TCP's three-way handshake protocol, how should attackers launch attacks? The attacker first intentionally initiated a handshake packet. After receiving it, the server puts it into the waiting queue and returns an acknowledgement. Secondly, the attacker will no longer send the third acknowledgement packet, thus the server will make multiple retransmissions (the Linux system configures the number of retransmissions through tcp_synack_retries), consuming a lot of extra overhead, and the waiting queue will be occupied, even the waiting queue will be full, eventually causing the server to be unable to receive the client's request. This is the attack.

I remember that after resisting the fifth attack, the Vietnamese army stopped there. It did not launch any new attack for a long time. Until more than 3 pm, the Vietnamese army actually "let dogs bite"! I was so impressed by the way the dog looked, The appearance is about the same as that of the domestic dog in my hometown. But there was no hair all over her body. The two eyes are still very far apart, The key is to run very fast. There was some grass in front of the position, and craters were everywhere bombed by the subsequent shelling. The 152-meter shell was a large crater with a diameter of 5 or 6 meters. However, this kind of "dog" can easily cross one with one jump, and there is no need to slow down in continuous jumping. The speed of impact is definitely not comparable to that of human beings. "
