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.Judo5 窨井Source authentication and resource isolation, that is, when the client and the server establish a reply, the source of the request is authenticated as necessary, and the authentication results are formed into a reliable white list or blacklist, thus ensuring the effectiveness of the server in processing services. If there are enough hackers and broilers and the authenticity of forged data packets is high, a better countermeasure effect can only be achieved by improving the processing speed and traffic throughput of the server.《杨光的夏天》又名《杨光的快乐生活第九部》是“60%的室内戏加40%的室外戏”，剧中的每一集就像一个相声段子，线索虽然单一人物却众多。45分钟的故事是独立成章的，但一集集下来就体现出了主人公性格的各个侧面。这个贯穿全剧、趣事多多的男一号就是杨光，是一个善良、淳朴、爱吹牛，一片好心总办坏事，想干坏事又常常干成了大好事的喜剧人物，因此围绕他发生的故事也非常有趣。CJ1, …
