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).民国初，山东济南武林高手“燕子李三”被官府斩杀。李三师弟李显隐退江湖，将绝世轻功传与徒弟李云飞、李云馨、李云龙。十年后李显师徒回到济南，与日本武士对决抗争，名声大振.百姓称，燕子李三回来了。抗战时期，李显师徒投入到全民抗战的洪流中。三徒弟李云龙薄弱的内心和膨胀的私欲，使他最终成为了彻头彻尾的走狗，不得善终。二徒弟李云馨开武馆，传授武艺。大徒弟李云飞体会到，凭借武林气节，单打独斗，不可能真正救国，毅然加入抗战。
