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).常识告诉我们事情越多,麻烦也越多;好吧，我知道了，季木霖看了眼表，那麻烦你了，我争取买到15号的飞机票。外表冷艳的吴志贞（桂纶镁 饰）身上散发着熟女的魅力，这对于男人来说是一种致命的诱惑，对于与她曾有过一面之缘的警察张自力（廖凡 饰）来说更是如此。他-妈的，他哪知道。
