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.
The mother's departure was even more hasty. A week after receiving the hospital in Shanghai, my mother died without being diagnosed.
I have also seen it spray on cars. The fuel burns to extinguish the flame for more than five minutes. When it finally went out, the whole car head was burned by more than half. Although I don't know the specific figure of the temperature, the comrades in the chemical defense class said it was at least 1300-1500 degrees Celsius, so I thought at that time, even the steel plate could melt into the flame of molten iron in a few minutes. It was not a piece of cake to burn this insect. Even if you are much bigger than the average wasp, may there be steel plates that are resistant to burning? After being ignited by the flame, it should be burned to ashes in an instant. But the result was not what I thought. After being ignited, the big wasp was quite resistant to burning. Actually flying around in the air for more than ten seconds before being burned, the air disintegrated and died. But this has become a good thing, It is precisely because it will burn to death for a while. So flying in the air with flames all over it must be either because of the sharp pain, Either they lost their direction because of something else, Anyway, it is flying around in the air, As a result, they hit many of their peers in the process of flying around. Then it ignited the same kind that was hit, If the ignited kind bumps into each other again, To ignite another kind, It just went through a couple of cycles, Most of the big wasps were set on fire, That will burn quickly. The sky is full of the sound of "crackling" burning meat, and there is a smell of barbecue burnt. The black corpses of wasps that have been burned apart and fallen and the corpses of wasps that have been smashed by bullets are piled up most. One foot is thick enough to reach the knee. That scene, I
This trip to the countryside gave me a deeper understanding of the basic situation in our country's countryside. We all went to places with high incidence of cancer, and personality is Shexian, the place with the highest adjusted mortality rate in the country. After investigation, the local environmental pollution is relatively serious. Although there are "Top Ten Well-off Villages" and more factories have brought economic benefits, they have also brought great pollution to the local environment. In the past, farmers had to drink polluted water. At the moment, deep wells have been drilled to drink clean and sanitary water. However, many factors in various fields still cause the high incidence of cardiovascular diseases and cancer in the area. Some families have seen the phenomenon of "poverty due to illness and returning to poverty due to illness". The implementation of the national new rural cooperative medical system has effectively relieved the economic pressure of patients' families. To a certain extent, it has curbed the phenomenon of returning to poverty due to illness and causing poverty due to illness, promoted the development of rural health services, promoted the change of farmers' concept of seeking medical treatment, and also enhanced the image of the Party and the government for private affairs. However, many farmers still do not know enough about this policy.

At this time, RST messages will be used to forcibly interrupt the connection.

In the Soviet Union, 26.8 million people died in World War II, Of these, 8.9 million (say 14 million) were killed by regular troops. The number of militias greatly exceeds this figure, The rest are civilians, The death toll of Soviet soldiers in World War II has always been a controversial issue. Because during the Great Patriotic War, many civilian men and women were temporarily incorporated into the Red Army, it was difficult to say whether they were regular soldiers or civilians or militiamen. Therefore, there were 8.9 million and 14 million soldiers killed. However, the West agreed with the former, with about 8.8 million soldiers killed in the Soviet-German battlefield. Less than 10,000 people died in the Soviet-Japanese battlefield. Nearly 90,000 people died in the battlefield of Sufen.
