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).　　仲間の場所を知っているというエネコの案内で向かった先は、行き止まりの地下水路。しかも、壁にあったおかしな柱のパズルを影片改编自Garth Stein所著同名畅销小说，聚焦一只名叫恩佐的狗狗，和他的主人——职业赛车手Denny Swift，恩佐跟着Denny学会了很多生活哲学。可是我没有技术啊。
