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.

"In order to bring back these three children, I built ten official seals alone. I can hardly remember how many people I dealt with back and forth." Liu Eryong recalled that the three children were practicing weightlifting in a sports school in Guangxi at that time, but they were slow to achieve results. It is time to leave school when they are old. For those who have not achieved results, the greatest possibility is to go directly to the society to work to earn money and bid farewell to weightlifting completely. Seeing that the three children actually have potential and meet the requirements of small levels, he proposed to introduce the three children back to Qingdao. "The introduction of children is not a trivial matter. In case they come to become champions, Guangxi Sports Bureau will hold the local coaches accountable. Therefore, the leaders of the Sports Bureau found the five coaches of the three children to sign and stamp their respective signatures to express their willingness to give up the children. The Municipal Sports Bureau and the Provincial Sports Bureau instructed them to sign and enter Shandong after the release. If the three children cannot practice, we will also bear certain responsibilities. Finally, we will cover ten chapters and have been busy for more than a month. The three children will be brought back. " Today, Liu Eryong also thinks that it was a very successful aid for them. Three Guangxi children came to Qingdao to study hard.
