Today we will talk about how to obtain your own ASN through LIR in RIPE. First of all, some people may wonder: Why choose RIPE? Isn’t APNIC or ARIN a good choice? The author has two ASNs, one under RIPE and the other under APNIC. When the author makes changes to some whois information, RIPE allows direct web access to make changes, while APNIC requires sending emails… which is more troublesome (actually it’s about the same)....
In this article, we will share with you how to register MAINTAINER, PERSON/ROLE, and ORGANIZATION objects in the RIPE DataBase. These objects are also necessary to register ASN. If you want to apply for ASN, you can refer to this tutorial. First, we need to register for a RIPE account registration website here. After completing the registration, we enter the RIPE Database and click “Create an Object”. Then we select the first “role and maintainer pair”....
Hi everyone, today I’m going to share how to use WireGuard to build an internal network. Previously, I shared how to install WireGuard on Linux systems. This time, we will use WireGuard to build an internal network. Why Build an Internal Network? Why does the author call this an “internal network”? Because the author may be in different places and wants to use this opportunity to add them all to the same LAN....
The clock is a very important thing for computers. It is not just about displaying the time in the status bar (or taskbar). If the clock is not correct (deviates too much from the actual time in the real world), it may cause some strange phenomena on the computer, such as: unable to view web pages (certificate issues), and even cause software crashes if the time difference is too great. Timeout login of various programs is also easy to occur when the time deviation is too large....
Recently, I replaced my switch and to test the speed of the internal network, I found this tool - iperf3 It is a testing program that supports Windows, Linux, and macOS and is mainly operated through commands. I often use it to test the speed between two different servers in different locations. So, here’s how to install it: First, go to the iperf3 official website and find the corresponding system (choose Windows for Windows, macOS for macOS, and Linux for Linux)....
Many people have bought iPhones, iPads, iPod touches, or Macs, but they don’t know that the built-in Spotlight has many useful features. Let’s take a look! How to use Spotlight (the method may be different in earlier versions): On iOS/iPadOS, swipe down on the home screen; on macOS, click on the magnifying glass in the menu bar (top right corner), or press “command” + “space bar”. Note: The search function of Spotlight and Siri has improved with each version, so some older versions may not have certain features....
Xbox Game Bar is a feature of Windows 10 that offers recording and streaming, performance monitoring, Spotify music control, and more. It can also be pinned to the screen. The best part is that Game Bar focuses system resources on the game, so players with lower-end computer configurations can enjoy smoother gameplay! Note: The author used Windows 10 (version 2004) and Xbox Game Bar (version 5.420) as examples. Different versions may look different....
Mac has a “Time Machine” that can easily backup the entire computer, and Windows also has a similar function! In simple terms, it will backup the entire computer, disk drive or folder (depending on the settings). The first backup will be a complete backup, so it will take longer. After the first backup, it will only backup the files that have been modified or created since the last backup to save space and time....
When we open the terminal, we will see a string of characters that says “username@hostname”, for example, John@Johns-MacBook. The hostname can theoretically be changed from the “Sharing” section in System Preferences. However, for some reason, it may not work on some computers. After searching for a few days, I finally found the answer: we can change the hostname from the terminal. First, please open the terminal and enter the following command....
The author has an old PC with 1GB of memory and Windows XP, which is suitable for light document use (Windows XP only requires 128MB of memory to operate). It can handle browsing some websites, but some large websites take a long time to load or cannot be used normally. If it is a general article webpage, it can still be managed. The problem is that the author wants to use the Gmail web version to send and receive emails, but it takes nearly a minute to load the standard Gmail webpage when the internet is smooth, and scrolling through emails is a disaster....
