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).六集诗选剧《零异频道：蜡烛湾 Channel Zero: Candle Cove》在10月11日首播，由Kris Straub所「着」的Creepypasta（转贴恐怖故事﹑都市传说）改篇，这剧讲述男主对一个80年代的神秘儿童节目十分偏执，因为他相信该节目引发了一连串的梦 魇及死亡事件。蜡烛湾是现实的都市传说，在当时一个美国论坛有人问一部诡异的儿童节目，名为《蜡烛湾 Candle Cove》，然后一群人指他们对这节目有记忆，而且还指发生了各种奇怪事件，但后来Kris Straub出来指这节目其实是他捏造的，然而不少人皆表示不相信，并质疑他是想隐瞒该节目的存在。特战大队队长金戈婚礼之日被日军所害，母亲惨死，新婚妻子柳文婷投河，金戈立志要为妻母报仇。共产党员戴金花奉命护送其去往敌后根据地。两人合力在敌后打响“抗日先锋第九大队”的名号。日军欲实施灭绝人性的“死海计划”，此时柳文婷意外出现，金戈年少好友钱柏豪也随之现身，两人竟以“夫妻”相称。种种谜团扑朔迷离，金戈与金花务必要赶在日军动手前破坏“死海计划”，一场争分夺秒的战斗就此展开……Score Category:胆小且温柔、出身于武士家庭的新海一马（冈田健史），剑术不行也拿不了刀，平日靠在私塾教普通百姓维持生计。小时候曾被妖怪救过的他，对妖怪存在一事，深信不疑，所以也坚持做着妖怪的研究。一日，他在一座废屋里，看到平日帮他管教其他学童的小雏正在和一个神奇的土器说话，当一马接过小雏给他的勾玉时，土器突然变化，跑出一名叫做天之邪鬼（本乡奏多）的妖怪。这一切，都因为小雏想见到亡母，并和她道歉。在小雏的拜托下，一马和天之邪鬼等其他妖怪一起行动，帮她如愿。It can be seen from the dribs and drabs of earthworms and customs that she is a good elder sister.
