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.
The Linux operating system has long established itself as a reliable, flexible, and high-performance environment suitable for servers, workstations, and embedded systems alike. However, even such a stable system can slow down under heavy resource load. If your RAM is maxed out and the CPU is constantly running at full capacity, it not only impacts usability but can also lead to lags, freezes, and even crashes.
This becomes especially critical when using Linux in professional environments—such as data centers, corporate servers, or development setups. That's why it’s important to regularly optimize the system and monitor resource usage to maintain responsiveness and stability.
In this detailed guide, we’ll go over practical ways to reduce CPU and RAM load. We’ll talk about process monitoring, managing startup applications, kernel tweaks, lightweight software alternatives, and other tips suitable for both beginners and experienced users.
Using an SSH authentication key for a server is considered much safer than entering a regular password. In this article, we will explain all the advantages of this method in detail and show you how to set it up on your server.
