The local people of my age pondered for a moment and said this sentence:
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).

In a real story, some workers stole it and asked for 80 yuan per pair. The original factory quantity was very small and involved all kinds of powerful relationships. Stance became more and more popular in China. Prices have also gone up, from an average price of 50 in the first half of the year to 80 ~ 100 + now. There are also factories that have good tags, but this is indeed a thing that has been sold by Haitao.
