112. X.X.4In 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).从小就拥有杂技表演天赋的菲利普·帕特（约瑟夫·高登-莱维特 Joseph Gordon-Levitt 饰）在街头卖艺时，邂逅美丽的街头音乐女孩安妮（夏洛特·莱本 Charlotte Le Bon 饰）。偶然的机会，菲利普得知纽约世贸双子大厦即将竣工。从此，菲利普就萌生了在这两座摩天大厦间走钢索的的想法。然而这疯狂的“艺术犯罪”却遭到了一系列的质疑和误解，但这并没有击垮菲利普的坚定信念，他深入调查缜密部署，先后得到走钢丝经验丰富的鲁迪爸爸（本·金斯利 Ben Kingsley 饰）的执导，以及让-路易（克雷蒙·史鲍尼 Clement Sibony 饰）和杰夫（塞萨·多姆波伊 César Domboy 饰）等人的帮助。在110层412米的云中，菲利普开始了他的钢丝行走。幻雪帝国的皇子卡索，不喜欢过当上王而失去自由的生活，他的弟弟樱空释为了使自己的哥哥实现自己的愿望，就不顾一切地去争取，但是由于做法太极端，以至于在卡索不知情的情况下，将樱空释杀死了。卡索无奈就成了幻雪帝国的王，但随后他又知道了一切，万分后悔，便决定去幻雪神山复活樱空释。一路上艰难险阻，在战胜了东南西北四个护法之后，最后终于成功。但是，在卡索还没有见到樱空释的时候，圣战再一次的暴发了，火族的皇子率兵打败了冰族，而卡索也因绝望而自杀。但是谁知，那火族皇子见到卡索后恢复了所有的记忆，火族皇子就是卡索的弟弟樱空释……杨丞琳、郑人硕在《灵语》搭档演出因爱女失踪而伤心欲绝的父母，两人分别在《红衣小女孩2》演出母亲、《人面鱼：红衣小女孩外传》演出虎爷乩身。她的角色颇具「复仇」色彩，她现在靠着每天都盯着和女儿定装时拍摄的亲密照片入戏，将自己代入自己真的有一个可爱孩子的生活里。《灵语》预计在11月初杀青。　　本剧以一个佛头为契机，情节曲折离奇，悬念叠出，连带出许许多多有意思的人和故事，并力求在吸引人的前提下，对蕴藏在生活喜剧表面之后的一些社会问题做了一个文化意义上的思索，为观众从最近的距离讲述了一个老百姓自己的故事……As one of Germany's troika, BMW has always been a representative of the pursuit of extreme control.
