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.本作品以街上的公园为舞台，是一部讲述带着柴犬的三位中年男性喋喋不休的对话剧。在他们的公寓里，有一个共同点。虽然每天散步见面，但是彼此的名字都不知道，以适当的距离感继续交往着。……苏樱一路漫无目的的走着。有内服的，有外敷的，包了一大包给他，并告诉他如何用。　　樊洪之女 樊梨花 对 薛丁山 一见钟情，不惜和家人反目，献关投薛。 薛丁山 却听信谄言，误以为 樊梨花 是杀父害兄的不义之人，将 樊梨花 赶出唐营。后来在 程咬金 等人的撮合帮助下，上演了“三休三请 樊梨花 ”的动人故事。最终几经离合， 薛丁山 和 樊梨花 终于结为夫妻。在他们的共同努力下，唐军终于平定了 西凉 之乱。与上次在大梁相见时薄姬式的端庄相比，又多了几分不同。　　北宋末年，宋微宗昏庸无道，宦官当政，民不聊生。山东郓城以宋江为首的三十六人等楸起了风起云涌的农民起义，他们杀富济贫，行侠仗义，令统治阶级闻风丧胆，令广大百姓拍手称快。义军不断挫败官兵的围剿，兵马粮饷不断充实壮大。
