For spoofing attacks, the first thing to consider is to choose the address. For the attack to succeed, the host on the spoofed IP address must not respond to any SYN-ACK packets sent to them. A very simple method that an attacker can use is to disguise only one source IP address, and this IP address will not respond to SYN-ACK packets, perhaps because there is no host on this IP address at all, or because some configuration has been made to the address or network properties of the host. Another option is to disguise many source addresses, and attackers will assume that hosts on some of these disguised addresses will not respond to SYN-ACK packets. To implement this method, you need to recycle the addresses on the list of source IP addresses that the server wants to connect to, or make the same modifications to hosts in a subnet.(three) the summary table of the registered fire engineers, the qualification certificate of the registered fire engineers and the photocopies of their social insurance certificates and identity cards;关于时装品牌拉尔夫·劳伦的起源和成长的纪录片改编自浩克威尔同名小说《大只佬和马叼丁》，讲述一名居身幕后，深藏功名的网络掮客（大熊）的小人物江湖故事：一日，多年分道扬镳的合作伙伴阿德上门寻求帮助，声称卷入走私和借贷纠纷。大熊因为早年阿德的失信行为，而对阿德的言论嗤之以鼻，打发他离开。不久，在拍档阿渡的介绍下，大熊认识了一名背景未知的 大哥木爷。木爷邀请大熊替他捧红旗下的一名网红直播梵一清，而一清正是阿德的亲妹妹。都市各方势力暗流涌动，谁能全身而退未尝可知。一桩20年未破解的少女谋杀谜案在20年后同样案件再度发生，它唤起了似乎已经平静的小城人们的记忆，曾经年少的山峰（宋洋饰演）成长为警察回到小城。因无法抹去的痛苦记忆让山峰再度追凶，在他寻求真相的过程中发现不仅仅自己，所有当年牵涉其中的人都因这桩20年前的谜案产生了翻天覆地的变化。江边小城夜色如水，雾气弥漫的追凶路上，一次次人性的拷问，一场场预想不到的危机与答案。Name of key parts, location, nature of use, construction area, fire resistance grade, presence or absence of fire fighting facilities, name of responsible person, ID card number and telephone number.本作讲述了泡沫经济时期傲慢的大小姐，却变成了孤独的中年流浪汉的二之宫小百合和她高中时代的同级生故事？以尾上慎二为中心展开的故事。有一天，小百合遇到了一本叫做《银计划的推荐》的书，知道了“人生中最重要的只有三件事”。之后在公园被不良少年扔石头，失去意识，小百合在高中时代穿越了。那里是同班同学？有慎二的身影。在剧中，小百合反省过多乱搞乱搞的高中时代，按照银色计划重新开始高中生活。
