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 simple understanding is that photometry is in charge of the light and shade distribution of the whole photo, with the central focus on photometry and uniform light and shade of the photo. The spot metering is more suitable for shooting the actors on the stage, that is, taking the actors as metering spots, and the photos taken are based on the brightness of the actors, rather than the shady scenes around the actors.

Fu Confucian Temple is located in Pan Palace, Zhongshan Road, Licheng District. Founded in the early years of Taiping and Xingguo in the Northern Song Dynasty (976 A.D.), it moved back to other places. Daguan moved back to its original place for reconstruction in the third year (1109 A.D.). The existing building still remains the original appearance of the early Qing Dynasty. It is the largest existing Confucius Temple in China and was listed as a national key cultural relic protection unit by the State Council in 2001. The main building, Dacheng Hall, is the main hall for offering sacrifices to holes. It has seven rooms in width and five rooms in depth. It is a typical Song Dynasty double-eaved temple style, with a beam-lifting wooden frame, overlapping arches, vertical and horizontal beams, and carved with little dragons, birds and animals, flowers and vegetation. The pillars of the temple are all stone, with a terrace in front, a handrail on the wings, and a tunnel on the lower side to worship the court. Panchi outside the court is built with a stone bridge of Yuan Dynasty. The bridge deck is paved with 72 rectangular stones, representing 72 of Confucius' favorite pupils. The east and west are two verandahs, the front is Dacheng Gate and Jinsheng Yuzhen Gate. Minglun Hall on the east bank is the main existing subsidiary building of Confucian Temple. The front of the hall, the open court, Panchi and the stone bridge are all well preserved. In the west, there are more than ten Pangong, Xiangxian Minghuan Temple and Zhuangyuan Temple. The display materials in the temple are very rich. In the center of the main hall of Dacheng Hall, Confucius' holy image is enshrined, and four matching and twelve philosophers are enshrined on the east and west sides. More than 500 cultural relics such as sacrificial vessels, musical instruments and relics of Quanzhou celebrities of past dynasties are displayed. Lingxing Gate is adjacent to Tumen Street. It was originally in the category of Fu Confucian Temple buildings and was later used for other purposes. In order to completely protect the Confucian Temple complex, in 2000, the Municipal Party Committee and the Municipal Government, as a key project, invested 120 million yuan to relocate the vegetable market and three enterprises and institutions to build the Confucian Temple Square, which not only effectively protected the site, but also became a place for citizens to relax and exercise.
