3472In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. 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).说完推李敬文，小声道：你也说两句。让你多看，每一事件都要吃透了。讲述了男女主人公关于对婚姻的承诺，对爱情的忠贞，对生活的热爱等永恒的生活主题。通过他们的故事告诉人们，“生活永远在回报那些热爱生活的人”。 继为三台制作“妒心密友”之后，Polyplus公司又准备开机拍摄另一部剧，计划安排Dome Pakorn与Mew Nittha合作。至于剧名如何，还须耐心等待片刻。剧情由@www.jijiv.com编辑，转载请注明。　　随即他对天真展开了热烈的追求，在社会上屡屡遇挫的天真逐渐被他的真诚所感动。同是二婚的两人，以为马上可以拥有简单温馨的婚姻。却不想遭到了郑现实家里的强烈反对。与此同时，天真的花心前夫成铭（王亚楠 饰）和女儿虫虫（刘宸希 饰）都希望天真能够回心转意，回到从前的家。一不做二不休的天真索性偷偷和现实领了结婚证，引起了一场又一场的家庭大战…… ©豆瓣If the wolf's King Jin does not let go, it will really be useless.
