英布见他自信的笑意，知道尹旭素有奇谋妙计，顿感惊喜，问道：莫非东来你有办法？快快告诉为兄。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.A fundamental and universal problem closely related to this aspect is related to the use of open DNS parser to launch DDoS attacks against Switzerland, an anti-spam organization. The open parser does not validate the IP address of the sender of the packet before sending back the DNS reply. Therefore, after the attacker deceives the victim's IP address, he can send a large amount of attack traffic to the victim, and the ratio of attack traffic to request traffic reaches 100: 1. DNS amplification attacks such as these have recently been used by hacker activists, blackmailers and blacklisted website hosts with great success.2. Peel off the network cable batch to see how bright the copper wire is inside. Generally speaking, if the network cable is made of recycled waste copper, or the copper used contains more impurities, the brightness of the network cable will be a little gray, just like the phenomenon that copper is oxidized. If it is a genuine network cable, its luster will be very bright, and it is six copper wires, each of which is so bright.上古时代，为了应对大旱，中国古老的两个部落东夷和九黎从小和奶奶一块长大、乐观自信的林佑开，在26岁获得锁王争霸大赛的冠军，登顶成为新一代锁王，但就在颁奖现场，他的女友埃拉带着警察出现在现场，指证阿开正是自家保险柜失窃案的嫌疑人。埃拉是著名安保集团龙氏锁业的老板龙啸坤的小女儿，事发当晚，龙家只有埃拉和阿开，而龙家监控摄像头拍下了阿开开锁的全过程，而只有阿开知道，这本是他和女友一次打赌，赌他是否能在30分钟内把埃拉家的锁全部打开。阿开怀疑自己陷入一场阴谋中。埃拉却认为阿开接近自己另有所图。最令人惊奇的是，龙啸坤却向警方宣布他的保险箱其实空无一物，他并没有丢失任何东西，而他的大女婿却刚刚雇人从他的保险箱里拿到了价值千万的财物。因为化们是从大粱鸿沟一带动身的，所以赶在了尹旭前面。
