Reset authentication takes advantage of the reliability of TCP protocol, and DDOS protection system responds to syn first. When the protective device receives syn, it responds to syn_ack and sets the Acknowledge number to a specific value (recorded as a cookie). When the real client receives this message and finds that the acknowledgement number is incorrect, it will send a reset message with a sequence number of cookie + 1. The source of the forgery will not have any response. In this way, we can add the real client IP to the white list. ?********皇宫，乾元殿偏殿内，永平帝靠在御座上，眼神空洞地仰望殿顶那珍禽异兽的雕饰花纹，心中默问神龟：为什么？为什么朕都认错了，还是不消停？这张家和郑家的事，什么时候是个头？才一日工夫，白虎将军的婚事尚未解决，就又出事了。天地伊始，万象皆新，巫族所镇守的九转玲珑石，集天地之气运，能颠倒日夜乾坤，其中的月华石更是有活生魂，药死人的奇效。28.

For example, what is determined at each middle-level regular meeting is transmitted to the middle-level. So, how is it implemented in the middle after the meeting? Do you need supervision and follow-up? How? Will supervision become a mere formality? How to feedback after the problem is implemented? Is the feedback true? Such issues need to be considered.如此做也是有些冒险了，尹旭之前心中也是忐忑不已，要是一举不能成功，那付出的代价可就大了。　　监狱里有一支由狱警们所组成的足球队，一天，典狱长（戴维·海明斯 David Hemmings 饰）找到了心灰意冷的丹尼，希望他能够成为球队的代理教练，帮助球队获得季度比赛的冠军。然而，丹尼却提出了一个令典狱长惊讶的要求，他希望亲自挑选犯人，重组球队。历险新片《地心历险记2：神秘岛》，源于17岁的肖恩·安德森（乔什·哈切森饰）收到的一组发自无人知晓的神秘岛密码求救信号。因为无法劝阻肖恩追踪信号来源，肖恩的继父汉克（道恩·强森饰）只能陪着他一起踏上这段南太平洋之行。而他们最终的目的地，是一座没几个活人亲眼见过的岛屿。那里风光旎丽，鸟语花香；珍禽异兽，应有尽有；金山火山，叹为观止；是座无奇不有的神秘天堂。他们俩只找到一个，愿意跟他们铤而走险的直升机驾驶员，嘎巴托（路易斯·古兹曼饰），和他美丽，坚强的女儿凯兰尼（瓦妮莎·哈金斯饰），四人一起踏上了这段寻岛之旅。一路上他们不仅仅拯救了岛上唯一的人类居民，更在地震冲击波淹没岛屿，埋葬其无限宝藏之前，逃出生天。这一切的一切，都发生在《地心历险记2：神秘岛》上，这是继2008年全球大获成功的《历险之旅1：地心游记》后，另一段惊心动魄的历险故事。
