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. ?1946年底，国民党军在豫南地区包围了我解放军某独立团。为延缓敌人的进攻，确保人民群众安全转移，我情工人员决定用假情报迷惑敌人，邓远达和叶淑婷被派往郑州执行这项特殊任务，邓远达成功打入敌人内部，在叶淑婷的配合和帮助下，与情报处处长费思清为首的特务斗智斗勇，出色地完成了一个又一个任务。通过不断的战斗历练，邓远达日趋成熟，最终成长为一名出色的情报工作者。而他和叶淑婷之间，也由最初的难以沟通逐渐转变为相互了解、信任、相知、相爱。就在他们完成任务准备撤离的最后关头，叶淑婷英勇牺牲,邓远达在完成任务后，带着二人共同的理想，继续走向新的战场在国际禁毒组织的严厉打击之下，金三角地区的毒源渐趋枯竭，大毒“深山猎人”为研制新型毒品冰 毒，来代替罂粟，秘密潜回家乡，使波澜不惊平原市一时暗潮汹涌…… 　　深夜，两伙贩毒份子为抢夺毒品在山区公路展开火拼，造成重大人员伤亡。为了巨额利润，贩毒组织又斗胆在迪厅交易，却被刑警队长艾强的女儿无意中发现，得到情报的缉毒支队队长李浩率队员及武警战士迅速赶到现场包围了迪厅但贩毒梁虎生却神秘失踪；然而，在逃脱警方的追捕后，梁虎生却又不明不白的被毒杀，数百公斤的冰 毒，在警方的严密布探之下偷偷运出市区，接着，大豪药业集团的副总慕在发现冰 毒的秘密后，又在一夜之间不明去向......利用发达的现代通讯技术和互联网科技，贩毒他子通过手机留言和网上E-mail展开源源不断的贩毒活动，甚嚣尘上，其间交织着毒品、凶杀、网恋、爱恨情仇，究竟谁是幕后元凶？其中又隐藏着什么重大匿情？现在总算是来到江陵城下，只要攻陷城池，天大的功劳便拿在手中了。黄豆笑道：这个什么素姑娘真是好心机：挑了这么个日子晕倒，又挑了这么个场合来报信，然后全京城人都知道我们田翰林有一位素姑娘了。Set the position and quantity.2. The coupling between the publisher and the subscriber is reduced. The publisher only publishes a message, and it does not care how the message is used by the subscriber. At the same time, the subscriber only monitors the event name of the publisher. As long as the event name of the publisher remains unchanged, it does not care how the publisher changes. Similarly, the seller (publisher) only needs to tell the subscriber (buyer) about the arrival of shoes, regardless of whether the buyer buys or not, or whether he buys other sellers. As long as the shoes arrive, the subscriber can be notified.
