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).其实我倒想看看《天河魔剑录》到底是什么鬼，我家天启几回合能把紫月剑打得屁滚尿流……喂，就没有人想看看天启本人，这个记者不是说天启年少潇洒、风度翩翩。士兵们重复着这个流程，已经不去想是否能击中对方，也不去想自己会不会被击中。徐建诚惶诚恐道：谨遵大王诏令。
