When a client accesses a server's web service, The client sends a message to the network card, The tcp/ip stack is part of the kernel, Therefore, the client information is transferred to the web service in user space through the kernel's TCP protocol, At this time, the destination destination of the client message is on the socket (IP: Port) that the web service is listening for. When a web service needs to respond to a client request, The destination destination of the response message sent by the web service is the client, At this time, The IP and port that the web service listens on becomes the origin instead, As we said, Netfilter is the real firewall, It is part of the kernel, Therefore, if we want the firewall to achieve the goal of "fire prevention", You need to set up checkpoints in the kernel. All incoming and outgoing messages have to pass through these checkpoints. After checking, those that meet the release conditions can be released, while those that meet the blocking conditions need to be blocked. As a result, input checkpoints and output checkpoints appear. These checkpoints are not called "checkpoints" but "chains" in iptables.中国首部反渎职电视剧《良心》由实力派演员郑晓宁担纲男一号出演反渎局局长宋子龙，王奎荣出演检察院检察长，吕凉出演市长。这也是中国荧屏上第一部以反渎职为题材的电视剧……Therefore, the essence of deliberate practice is to buy SSD hard disks, not to sell coolies, not to help best-selling authors market, shouting warm-blooded slogans: 10,000 hours, today, do you insist?二十年代末，上海公共租界巡捕探长方鹏因系列连环凶杀案，卷进了一个复杂的案件之中。国民政府实业部长孔培之派心腹手下杜鹃深入上海滩，企图破坏刚刚由地质学家萧安邦领导的铁矿开采计划，意图囤积居奇，抬高铁矿价格，达到中饱私囊的目的。不料，这个大铁矿的发现引起了英、美、日等多国列强的垂涎，各方不择手段，企图夺取铁矿开采权。方鹏抽丝剥茧，逐渐找到意图夺取铁矿的最大黑手原来是日本人。最终方鹏在钱菲菲等一群爱国志士的帮助下，揪出了中饱私囊的孔培之，击杀了实为日本人的杜鹃，保护住了铁矿。刘小念前脚刚被带走，孟小蔷后脚就投奔到了黄家，还被安排在刘小念的卧室。点开几个帖子，陈启顿时了然。谢陛下。
