In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).
At first I thought Zhao Mingkai's memory was almost over, I didn't think the real "climax" had just begun, Compared with what he later said, The previous two attacks were just "appetizers", When he said this, there was a very representative action. It is to put the cigarette end that has been smoked to the end and not put it out in the ashtray in front of you. But threw it hard at the ground, With his feet, his eyes became combative from the regret when he remembered Zhou Xiaolin just now. Although I didn't know what he was going to say at that time, I could have a premonition from his facial expression that the contents were at least serious to him and even to the more than a dozen soldiers on the entire 142 position.

Because the attribute income is linear and does not decrease, when someone smashes a huge amount of resources to pile up the defense, low-percentage characters such as Blowing Snow will be the first to hit single-digit damage.
