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).Netflix宣布续订刚刚播出的新剧《毒枭》第二季。韩信比谁都着急，西魏国是在自己的掌控之下，若是刘邦就此死了，汉国基本上也就完蛋了，自己的宏图伟业也将就此成为泡影。他们在神殿中发现一个战斗陀螺“索布莱兹”。“白色之心，带着天马之翼打开新时代的大门……这是我们亚特兰蒂斯的传说，创造的时刻已经到来。用它的力量建设我们新的乌托邦。”遵从领袖巴基姆的话，少年海利奥斯拿起了索布莱兹。2.
