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.月牙是乌善族人，她被王爷收养了十年。就在她与王爷之子逸辰成亲之时，军费紧张，王爷叫士兵寻找金矿，结果士兵中毒回来。说其他人被乌善族杀死了或活捉了。月牙的母亲也是中此毒而死，月牙心中的仇恨再被点燃。她来到百雀谷做卧底。开始月牙经历了重重磨难，终于得到了信任。当她被乌玛害时，乌沙救了她，原来当年就是乌沙放了她。乌沙原来早就爱上月牙。珍珠得了瘟疫，月牙为她熬药。后来大祭司也得了瘟疫了，月牙为她熬药，于是乌玛下药陷害月牙。月牙被关进了地窖。后来所有族人都得了瘟疫，月牙拼死拼活的救他们，自己累倒了。这是乌沙知道了真相，急忙救了月牙，当他要惩罚乌玛时，乌玛说她爱乌沙，她不想让月牙抢走乌沙。月牙叫乌沙放了乌玛。于是乌沙提议立月牙为圣女。（圣女要嫁给首领乌沙），在新婚之夜，月牙带着圣物跑了。乌沙愧对族人割脉自尽。但月牙知道王爷要攻打百雀谷后，及时出现，交出圣物，替乌沙包扎伤口，，此时月牙已经爱上了乌沙。但却把军队引来。逸辰和乌沙要决斗。月牙面对两个所爱之人，左右为难…。在香港街头，一群人在听一个说书人讲故事。一辆警车开来，以妨碍交通为名将说书人带回警局。有两个人为了继续听故事而跟警察动手，为的是能和说书人一起被带回警局。说书人说的是多年前一个著名的粤剧编剧南海十三郎的故事。十三郎生于广东南海，在家中排行十三，父亲是江太史公。在一次慈善舞会上，十三郎对上海女子莉莉一见钟情，并追随其到上海，但莉莉对他并无好感。影片讲述将犯罪组织成功转型成金融企业后，想要金盆洗手的黑帮二把手美玉(金惠秀饰)的故事。2018-03-05 11:42:07戚将军来了？这么快？胆大的士兵已登上城头，眼见鬼倭被围，立刻报信。
