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).

咸丰十一年帝崩，传位于年仅六岁之小皇子载淳。帝崩前授命肃顺、载坦等八人为顾命大臣，于是慈禧遂与恭亲王奕密谋诛肃顺，定为“辛酉政变”。之后，慈禧与慈安两宫垂簾，并由恭亲王奕诉为议政王，把持政务的六岁小皇子储立为帝，改为同治年号。同治登位年仅六岁，一切政务皆由生母慈禧太后和恭亲王主持。慈禧本是一位极有野心之妇人，两宫垂簾后，便以太后身份，在政事上每加意见，干预朝政，恭亲王早就看出其政治野心和权力欲望，故在处理政事时明争暗斗，冲突遂起。同治因慈禧专注于政事上，加上慈禧之专横，在缺乏生母关怀下，同治更加亲近宅心仁厚的慈安太后，因此慈禧与同治之间的母子感情便日渐疏离。
