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).莱斯利希望能在国家公园管理局的一块土地上中标，但面临着包括她的新死敌罗恩·斯旺森在内的一个团体的竞争。同时安迪和阿普里尔是m。yakubd.cc担心他们现在又老又无聊。There is also a sense of belonging that cannot be found in Huang Weiping.
