Teach you to troubleshoot the reason why the external network cannot access the internal network server through the public network IP The relocation of the company has resulted in the loss of the function of accessing the internal network from the external network. Today, we are here to check the problem. The problem analysis is that the router configuration is good (I checked to make sure it is normal, just in case) because the hardware is usable before, the hardware has not been replaced, and the broadband account network has not changed. Because it is a relocation, and then the hardware has an optical cat+switch+router+server, it is speculated that the IP allocated is different because of different levels. To confirm whether your network IP is really the process of public network IP troubleshooting, because you don't know anything about it, you first checked the configuration of the router, took the opportunity to sneak in and see how the boss configured it. After confirmation, it is found that there should be no shortage of configurations. Then I confirmed the routing level of the server. After logging in to the server through the intranet ssh, I found that it was possible to log in. Then I confirmed that it should not be a level problem (because I didn't go to the company and operated remotely). The last thing that was most unlikely was the problem of public IP, because according to my original idea, the company had public IP before, but only moved the environment, The account is old, so there should be no problem. When I opened ip138.com, I found that my IP address was the old public IP address (which confirmed my belief that the public IP address was still old, indicating that it should be a hardware problem), Then query that the IP address on the router is an intranet IP address (this is different from the one queried in 138, which has already explained the problem. If this is different from the one queried in 138, it means that the IP address is not a public IP address, but I didn't realize it at the time). I started to look at the hardware level again. It seems that there should be no problem. So I plan to confirm from the beginning and contact the broadband provider first, but I can't get in touch. So I contacted the router manufacturer and got in touch. The router manufacturer said: In most cases, if there is a public IP, the router IP must be a public IP. It happened that Telecom contacted me and asked Telecom. Telecom said that the public IP was lost because of your relocation, and then asked them to give it a new IP and restart the router, On the router page, it is the public IP again. So far, the problem has been solved. The above is my idea of solving the problem, for reference only. Tips You don't have to worry about whether the router has received your external network request, because as long as the virtual host is set up, as long as the router receives the request, it will automatically forward it to your internal network server. The wan ip displayed on the router's home page (that is, the ip displayed on the router) must be your current ip to the external network. If it displays an internal ip, it must be the internal network. Don't hesitate to call customer service directly. About the second point. Sometimes, there are some configurations on your optical cat, such as multi-level and multiple routers, so the optical cat will configure your router with an intranet IP address. At this time, you should confirm whether the optical cat has a configuration. I didn't understand what this was about at first, but later I learned that because the public IP keeps changing, the router will report your real-time public IP address to the dynamic domain name provider, and then the dynamic domain name will change your domain name resolution address to the latest IP reference https://service.tp-link.com.cn/detail_article_2576.html Virtual Host Settings https://m.300.cn/itzspd/385162.html Dynamic domain name binding -
About php xdebug debugging thinkphp on vscode Sharing experience - novice installation experience This article is a companion to the previous one. If you are a Xiaobai who has never used it at all, it is recommended that you first read the first article: novice installation of xdebug. The purpose of this article is to install xedebug and debug thinkphp. This article mainly shares the problems encountered during installation to enlighten readers. Problem encountered in the body: After installing xdebug, vscode cannot listen to the browser. Currently, xdebug has two versions and three versions. If you don't know your own version, it is recommended to configure version 3 first, and then change it to version 2 if you are sure that it is not enough # Add it in php. ini (this is version 3) xdebug.mode = debug Xdebug. start_with_request=yes # Added in php.ini (this is version 2) xdebug.remote_enable = 1 xdebug.remote_autostart = 1 Xdebug. remote_port=9000. You can try both configurations. Maybe you can. If your English is good, you can read vscode for xdebug directly: -

[Notes] The native js returns to the top or bottom of the page manually Foreword When browsing the Enshan Forum, the author always has some posts to pull to the bottom to reply, and the most extreme is that the posts are very long, and I don't want to pull them by hand, so I wrote this code (the code obtained from the search) # This code is applicable to the chrome browser, and can be used after copying, pasting and saving to the bookmark javascript:(function() { #Determine whether the scroll bar is at the top. If it is, go to the bottom 10000 if (document.documentElement.scrollTop == 0) { window.scrollTo('10000','10000'); #Determine whether the scroll bar is at the bottom. If it is, go to the top 0 } else if (document.documentElement.clientHeight +document.documentElement.scrollTop +50> document.documentElement.scrollHeight) { window.scrollTo('0','0'); }else { #In other cases, go to the bottom to reply window.scrollTo('10000','10000'); } })(); Precautions are only applicable to the hidden content of the page conclusion that is not loaded like the Ajax asynchronous request.
