When it comes to encapsulation, the behavior of the encapsulated object is generally preferred over the state of the object. But the opposite is true in state mode, The key to the state mode is to encapsulate each state of the thing into a separate class, and the behaviors related to this state are encapsulated inside this class, so when button is pressed, only the request needs to be delegated to the current state object in the context, and the state object will be responsible for rendering its own behaviors. At the same time, the state switching rules can be distributed in the state classes in advance, thus effectively eliminating a large number of conditional branch statements that originally existed.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.
