也没那么容易。地主二代，好歹得有点土豪劣绅的气势。香儿点头道：嗯，是不能攻。是一部以「職場騷擾」「性騷擾」「孕婦騷擾」等「騷擾」為主題展開的故事。唐澤飾演經營超市的老字號公司內「企業規章制度部門」的室長，以自己獨特的手法和視點解決來自大家的難題和奇怪問題。在アガステア作为研究人员工作的黑井津灯香和佐田卷博士一起渡过了许多难关打倒英雄的怪人能做得好吗！？这个人太厉害了，这种情形下，居然还能利用各方形势……他说了一半，就停住，闭上眼睛，仿佛在整理思绪。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.
