In 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).汪正松肃然道：此乃本官分内职责。刘邦这才坐回原地，但是心情却是无比的沉重，事实却是如此。柳垠渽（李诗英 饰）是棒球队“蓝色海鸥”的忠实球迷，某日，在一家KTV里，柳垠渽一家人意外邂逅了球队“红梦人”的球员朴茂烈（李栋旭 饰），要知道，如果不是朴茂烈，“蓝色海鸥”才不至于在比赛中落败，失去得到冠军的机会。一想到这个就气不打一处来的柳垠渽向朴茂烈发起了挑衅，引起了一场混战，这“壮观”的场面被录了下来传到了网络之上，一时间，朴茂烈的人气大跌。 为了挽回朴茂烈的声誉，他的经纪人召开了记者招待会，宣布柳垠渽即将成为朴茂烈的贴身保镖。就这样，一对冤家硬是被撮合到了一起，整天吵吵闹闹的生活就此展开，还时不时地碰撞出小小的火花来。作为一位深知保密价值的爱国者，爱德华·威尔森(马特·达蒙饰)因童年的悲剧在心底根植入荣誉的情愫。1939年，正在耶鲁大学就读的热情而敏感的威尔森被秘密社团“骷髅会”看中，将他招募为会员。这是一个与美国政界、商界和教育界密不可分的学生组织，3位美国总统以及多位联邦大法官和大学校长都出自“骷髅会”。该组织之所以吸收威尔森，是因为他头脑敏锐、履历无暇，并且对国家非常忠诚。而在前方等待威尔森的，是即将开始的谍报生涯。桐山涟#主演4月东京电视台广井王子原案新作的深夜剧《CODE：M コードネームミラージュ》，要润、佐野ひなこ、武田真治、萩原圣人、石丸谦二郎共演。4月7日开始每周五深夜1：23播出~Temple of Heaven
