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.影片以汪星人的视角展现狗狗和人类的微妙情感，一只狗狗陪伴小主人长大成人，甚至为他追到了女朋友，后来它年迈死去又转世投胎变成其他性别和类型的汪，第二次轮回狗狗变成了警犬威风凛凛，再次转轮回，又成了陪伴一位单身女青年的小柯基犬。在经历了多次轮回之后，最终回到最初的主人身边。The second method: recovery in case of key failureIf we don't have a Computer class, then CPU, Memory and Disk will hold instances and generate relationships with each other, which will cause serious dependence. Modifying one class may bring about modifications to other classes. This is not what we want to see. With the Computer class, the relationship between them will be placed in the Computer class, thus playing a decoupling role. This is the appearance mode!2. 5. Artistic Performance
