The Slowloris attack exploits a vulnerability in the web server (or an unreasonable parameter configuration) and directly causes a denial of service. Slowloris is an attack method proposed by famous Web security expert RSnake in 2009. Its principle is to send HTTP requests to the server at a very low speed. Since the Web Server has a certain upper limit on the number of concurrent connections, if these connections are maliciously occupied and not released, all connections of the Web Server will be occupied by malicious connections, thus new requests cannot be accepted, resulting in denial of service.打了一个车，没有一会儿，陈启就来到了一个有些老旧的小区。她感觉身边少年正低头审视她，便仰起脸，看着他的眼睛，先轻唤一声：哥哥……少年对上她纯真的目光，犹豫了一下，微叹了口气，将要问的话吞了回去。很多人也开始重新审视这个大结局。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.此剧讲述被领养到美国的宝美，在数十年后重回故乡孔多利村里定居后，因不适应农村生活而发生冲突，与渐渐融入纯朴的农村生活的故事。/v flee
