If you're managing Linux servers, encountering systemctl is inevitable. This utility has become the de facto standard for controlling system processes across most modern distributions. Let's explore how to leverage this tool effectively and avoid common pitfalls when working with system services.
This guide walks through cron fundamentals, scheduling syntax, and the mistakes that commonly derail otherwise well-planned automation.
DirectAdmin is a convenient and lightweight control panel suitable for administering sites, domains, mail and other server tasks. Unlike other solutions, installation of DirectAdmin requires manual license activation. Inside is a step-by-step installation guide.
An error has occurred in the IP address module. The IP address “x.x.x.x” is already in use. Sound familiar?
In this article, we will look at how to quickly fix the error and get back to work.
When you're setting up a server for your specific tasks, you want it to run fast and clean — without extra stuff getting in the way. But here's the catch: many modern Linux distributions, especially those using systemd, automatically start a bunch of services by default. Even the ones you don’t need. These background services can quietly eat up system resources — and sometimes even become security risks. Let’s go over how to find and disable services you don’t actually need on popular Linux distros like Fedora, CentOS, Ubuntu, and Debian.
If you’ve ever plugged a USB stick into a Linux system and suddenly realized you can’t copy, delete, or change anything because the drive is mounted as read-only — you’re not alone. This is a pretty common issue among Linux users, whether you're on Ubuntu, Fedora, Arch, or another distro.
If you are just starting out with a VPS or VDS, it is important to think about security right away. One simple and reliable way to limit unwanted connections is to configure a firewall. This guide will show you how to do this with UFW, a lightweight utility for managing network rules on Ubuntu.
If you’ve ever played old floppy disk games or typed commands into a black screen, you probably remember DOS. And if you missed that era — this is a great way to experience it. FreeDOS brings back that retro vibe, and Linux with QEMU makes it easy to set up without much hassle. All you need is a bit of free time, a few terminal commands, and either some nostalgia or curiosity. In this guide, I’ll show you how to get FreeDOS up and running on your Linux machine so you can relive the past with classic software and games.
Sometimes, it's much more convenient to control your smartphone directly from your PC rather than reaching for it. Scrcpy does this perfectly — it's a lightweight, free, and cross-platform program. It allows you to mirror and control Android devices over Wi-Fi or cable.
These days, when deploying websites, a common question arises: how can you set up a reliable, secure, and easy-to-manage infrastructure? In this article, we’ll walk you through setting up Caddy — a modern web server and reverse proxy that’s perfect for small to medium-sized projects, especially if you don’t want to spend hours configuring Nginx or Apache.
We’ll cover how to install Caddy on Ubuntu, create a configuration file for serving static files and PHP applications, and connect a custom SSL certificate — a particularly relevant topic when using proxies like Cloudflare.
