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.蒯彻轻轻摇头：有可能，但是不绝对，齐王虽然没有和别人提及，但是只要有心人到齐王的家乡去仔细打听，也能查到一些东西，会不会有别人……可是谁有这个动机呢？韩信突然间心头一动，想到些什么，难道会是他？想起自己是如何ún到今天的局面，也是他一手促成的。A1.1. 7 Autonomic nerve examination影片讲述李连杰饰演的广东武术名家洪熙官被官府赶尽杀绝，他只好带著独子洪文定浪迹天涯，被陈松勇饰演的富翁收留为护院师父。另一方面，老千母女叶得娴与邱淑贞也对富翁打主意，跟洪熙官父子展开了一段化敌为友的关系。1979年深秋的一个晚上，在孔雀坝插队的上海知识青年林放和陆静，因为一个意外事件，在民兵追赶下逃进了中缅边境的山林，慌乱中他们误入中甸境内的黑风谷……黑风谷是中缅边境上一个具有神秘色彩的翡翠采石场，这里是缅甸翡翠王温沙的地盘，任何人不得随便出入。林放和陆静被当成奸细，按照黑风谷的规矩，装进麻袋，就要扔进大江里……在这紧急关头，温沙听出林放和陆静的上海口音，他出人意料地留下了这两个年轻人…… 　　经过一系列的考验，温沙觉得林放是个非常正直，且又十分重义气的人，他决定派林放去上海，把十块价格昂贵的翡翠毛石交给一个叫金子荣的人。可是，他却把即将分娩的陆静扣留在黑风谷当人质…… 　　林放背着十块价格昂贵的翡翠毛石，历尽千难万险，终于回到了上海，可谁知金子荣又偷渡去了台湾……Okay, I haven't passed 132 yet.
