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).一个打扮得像贵族的男人手牵四只恶犬横行霸道，每一只恶犬都引出了一个可怕的故事。幼年时喜爱收集昆虫的男子成年后与一个女孩同居。逐渐的，他发现这个女孩体内居然寄生着他幼时所收集的昆虫，女孩把男孩捆在床上，而她体内的昆虫成为了男孩的饲主。脸上有胎记的女孩在学校饱受欺凌，就连在梦中也得不到片刻休息。某一日，当她从噩梦中挣扎着醒来时，她发现，现实变成了梦境的延续。一条鳄鱼吃掉了一个成年男子，人类终究有一天会被大自然反噬。一个男人杀掉了自己的妻子，却仍旧能感受到她残留的气息，为了寻找这气息，男子反而迷失了自己。
