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).　　故事从一紧张而忙碌的早晨拉开序幕：连续的案件让刑警队的侦察员们应接不暇；自杀、他杀、抢动、盗窃……谁也想不到，表面上毫无关系的件件案子，却串联掩盖着一个将震撼整个城市的大阴谋！就在破案的紧急关口，当地首富葛振海的一百万现金忽然被人从股市里划走，取款人当天被杀，年青的侦察员丁晓雷奉命调查此案，在艰难的侦察中发现嫌疑人李少非竟敢是葛振海三十多年前被父亲抛弃的亲兄弟。就在丁晓雷意欲揭开这层面纱的将破未破之际，风云顿起……广告公司的小老板，刑警队长钟爱的女友，被追辑的逃犯，戴着面具的摇滚歌手，最后还有丁晓雷心爱的女朋友肖肖，全部卷入此案，以种种面目出现着，扮演着种种角色，在一次次的山穷水尽，进退维谷中，丁晓雷身不由已地陷入漩涡中……追踪办案的刑警大田被暗杀，案件惊动了国家最高公安机关，上亿元的期货投资诈骗案在阴谋的掩护下冠冕堂皇地招摇过市；女公安局长的独生女与被灭口的取款人在银行碰面，录像带被神秘的幕后人拍下；每一个人都在陷害别人的过程中被人陷害。欲望编就了无数尔虞我诈的阴谋，欲望培育出靓女俊男Has the landlord summed up
