晚上好好睡一觉，明早起来就会轻松好些。啪啪……沈飞敲着键盘，准备回帖，这时夜水灵风又发言道。So let's explain the rules of iptables in a common way. There was an analogy before, Each "chain" is a "checkpoint", Every message passing through this "level" must match the rules on this level. If there is a match, The message is processed correspondingly, For example, you and I are like two "messages" at the moment. Both of you and I are going to enter the customs at this moment. But the duke has a life, Only the imposing person can enter the customs, Those who do not meet this requirement are not allowed to enter the customs. So the soldiers guarding the customs followed the "rules" formulated by the duke. I began to look at you and me. In the end, you entered the customs smoothly, and I was rejected. Because you met the standard of "dignity", you were "released", while I did not meet the standard, so I was not released. In fact, "dignity" is a kind of "matching condition", "release" is a kind of "action", and "matching condition" and "action" form the rules.马丁·贝伦斯为德国联邦情报局工作。一天，他从他的一个联系人那里得到信息，导致无人驾驶飞机对一个被扎希里斯坦政府通缉的恐怖分子发动袭击。几天后，恐怖分子袭击慕尼黑一家餐馆，报复无人机袭击，他的生活迅速失控。马丁试图找出谁是这次袭击的责任人，并了解到答案就在离家不舒服的地方。A class has only one instance and instantiates itself and provides this instance to the entire system.
