Zip is a command-line tool for compressing files and folders. Compression makes transferring and storing data faster and easier, and it’s handy for emailing. Unzip does the opposite—it extracts archives.
Linux provides a wide range of system services (such as process management, login, syslog, cron, and more), as well as network services (remote access, email, printing, web hosting, data storage, file transfer, DNS, DHCP, and so on).
In essence, a service is a process or a group of processes that run continuously in the background, waiting for requests—most often from clients.
Linux offers several ways to manage services: start, stop, restart, or enable them to launch automatically at boot. Nearly all modern distributions rely on the same process manager — systemd.
When you're working on a project as a team, Git is essential. It tracks changes, lets you work in parallel, compare versions, and roll back when needed. Most people use GitHub or other cloud-based platforms. But what if you can't—or don’t want to—store code outside your company? In that case, setting up a local Git server is the way to go. And yes, you can do it on Windows Server. One of the easiest tools for the job is Gitea — it’s lightweight, doesn’t require complicated setup, and runs great on Windows.
If your server has limited RAM and the disk isn’t particularly fast, ZRAM can help speed things up noticeably. It uses a portion of your memory as compressed swap space — meaning you can fit 2–3 times more data into RAM, and it's still faster than writing to disk. In this guide, we’ll show you how to enable ZRAM on Ubuntu 24.04, and how to combine it with a regular swap file if needed.
If you’ve ever tried installing Linux and ran into weird boot errors — especially when Secure Boot is involved — you’re not alone. In this article, we’ll break down what Secure Boot actually is, what shim files are, and why they sometimes get in the way of booting Linux — in simple terms, without diving too deep into technical jargon
When you want to check what’s going on with your system via terminal, the first command that comes to mind is usually top. But there’s a modern alternative — Btop++. It’s a powerful resource monitor for Linux that gives you detailed info about CPU usage, memory, disks, network activity, and running processes. Btop++ is written in C++ and is the successor to bashtop and bpytop, created by the same developer.
Sometimes you need to access files on a remote server as if they were right there on your computer. Maybe you want to back up some documents, upload vacation photos, or just have an easy way to work with files from different places. One of the simplest ways to do this is with WebDAV — a reliable, time-tested protocol that turns your server into a network drive. It works over standard HTTP or HTTPS and is supported on almost every platform out there. Let’s break down what WebDAV is, how it works, and how you can get it running — with examples for Windows, Linux, and mobile.
When a server receives hundreds of requests per second, it's critical that the system continues to run smoothly. That’s where a load balancer comes in — a tool that distributes incoming requests across multiple servers to keep everything fast and stable. In this article, we’ll look at what a load balancer does, how it works, the methods and algorithms used in real-world infrastructure, and why cloud-based solutions are increasingly replacing hardware-based ones.
Podman is a modern container management tool often seen as an alternative to Docker. It lets you run, manage, and group containers — but does so in a way that's simpler, more secure, and more flexible. Unlike Docker, Podman doesn’t rely on a background daemon. This means that if one part of the system fails, everything else keeps working. Another key feature is that containers can be run without root privileges, reducing system-level security risks. It’s also convenient that Podman is compatible with Docker — most familiar commands work in much the same way.
Your server is up, your website loads, everything works. But after a couple of months—problems start creeping in: vulnerabilities pop up, errors appear, some things stop working. Why? The answer is simple: you forgot to install updates.
Ubuntu servers, especially those with SSH access, are constantly being scanned and attacked by bots looking for vulnerabilities. If you skip updates, you’re risking data leaks, downtime, or even hidden crypto miners silently hijacking your resources.
Regular updates patch security flaws, fix bugs, and improve system stability. This is especially important on VPS plans with limited resources, where a small issue can quickly escalate into a major outage.
To avoid unnecessary risk, it's best to enable automatic updates right after setting up your server. Doing everything manually is slow and unreliable—especially if you're away or simply forget. That’s where unattended-upgrades comes in.
