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.Http://www.jiemian.com/article/2145181.html　　在家里，高小点一直被老爸逼着吃他亲手做的的蛋糕。在学校里，他是一个安份守纪的孩子，老师从不批评他，可是也从不表扬他，老师还常常忘记他的名字。在朋友圈子里，他梦想成为朋友心目中的超人，打败作恶的怪兽。但他这个愿望似乎从未实现过，扮演超人角色的真正孩子王永远是牛飞天，而他始终扮演着被超人打的怪兽。他一直期盼着生活能出现一点激情，哪怕只是一点点，他就心满意足了。可是就是那么一点点，老天也不给他。他的生活还是一复一日的一复一日。Unfortunately, it has already,一定要洗白，不洗白，永远只是海盗，再强的海盗，也有被剿灭的一天。田中哲朗是一个稍嫌平庸的普通高中生，因为某些特定的原因而转入了只有女生的五光学园。尽管比规定的时间整整晚了一个月，但哲郎还是心安理得的过起了看上去非常普通的生活。不久，超出其常识的事情就一次次接连发生在哲朗的身边，原本以为只是大脑秀逗的学园美少女战队“KOI KOI7”竟然扬言其使命是保护世界和平和保证哲朗的安全，更奇怪的是这个7人战队的成员根本只有6个人。然而在更多人眼中，能不时瞅到草莓短裤和被女生簇拥，哲朗的学园生活还是充满了让人羡慕的地方。本作没有深入讨论什么“宿命”之类的沉重话题，而是完全将轻松欢快的气氛带给大家。Attackers actively try to shift the learned boundary between abuse and reasonable use to their advantage.
