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.Replay被海昏刘贺强抢的美貌绝冠县令之女李静香，新婚之夜吞下私定终身叶孤航赠与的凤鸣石，变成厄难之体的她意外让刘贺之子惨死，被活埋千年之后被盗墓者们意外放出……FOX续订《嘻哈帝国》第四季。这是一部独特的家庭故事剧，以嘻哈乐（Hip-Hop）世界为背景。主人公Lucious Lyon（Terrence Howard）是一个迷人的、精明能干的乐坛超级明星，正准备带领自己的帝国娱乐公司上市。他从小在街头长大，养成了争强好胜的性格。为了保护自己的音乐帝国，他永远不会放弃任何一场战斗。但是现在和他争夺王位的是他前妻和三个儿子，他不可能再像以前那样不择手段。来来去去，却也成就了唐顺之，他有更多的时间去学习研究游历，终成一代心学大师，路过山阴的时候还收了徐文长。Http://www.jiemian.com/article/2173449.html
