Introduction In the daily use of Linux systems, especially for cloud host users with limited disk space, many people will encounter the situation where the disk space is gradually filled. There are many reasons for the shortage of disk space, such as a large number of log files generated by the system, Docker images occupying space, etc.

When we use Linux system, we often encounter the need to run commands (or scripts) at startup. This article takes the startup and running of tailscale relay server DERP on debian11 as an example to summarize the three most commonly used startup running commands (or scripts)...

Because Tailscale does not have an official relay server in China (you know why), although it can still be used (using foreign relays), the latency is very high, and from the bottom of my heart, public relay servers are not pleasant (do we all wear underwear together?). Want low latency...

I have previously written an article about how macOS can mount a shared SMB folder at startup (see: How to automatically mount a shared SMB network disk at startup in macOS), and this article will briefly explain how Debian 12 can mount an SMB folder at startup.

There are three ways of ssh remote login authentication: Password, Keyboard Interactive and Public Key. The first two methods are password authentication, but the first one does not require delivery, while the second one requires interaction. Generally…

Preface This article is mainly for record purpose, so as to save you from installing various software every time you install a new Debian virtual machine. Why mention Debian virtual machine? Because Debian LXC has already installed most of the basic software once it is newly created. The following…
