Explore the world of Linux with clear, approachable guides. Whether you’re just starting out or looking to sharpen your skills, you’ll find something to brew your interest here.
I’ve been running my own homelab for years, and I’ve learned the hard way that a solid backup strategy is crucial. After trying out various backup tools in 2025, I kept coming back to rsync due to its flexibility and reliability. This year, I’ve been focused on fine-tuning my backup scripts to achieve consistent snapshot rotation. Don’t bother with overly complex backup solutions - rsync is a powerful tool that can get the job done.
I’ve been using Linux for years, and one thing I’ve learned is that managing jobs is crucial, especially when running long-running commands. You don’t want to keep your terminal open for hours, waiting for a command to finish. That’s where nice, ionice, and nohup come in - they’re essential tools for managing and prioritizing Linux jobs. In this article, I’ll share my experience with these commands and how to use them effectively.
I’ve seen this go wrong when you’ve got a bunch of resource-intensive tasks running in the background, slowing down your entire system. In my experience, using nice and ionice can be a game-changer. These two commands let you control the priority of processes and disk I/O, which is especially useful for homelab servers or small machines.
The nice command is all about setting the priority of a process. By default, Linux gives every process a nice value of 0. You can adjust this using the nice command, where negative values mean higher priority and positive values mean lower priority. For example, if you’ve got a command that’s hogging all your resources, you can run it with a lower priority like this:
I’ve been running my own homelab for years, and like many of you, I’ve had my fair share of DNS resolution issues. Last year, I decided to ditch my router as a DNS server and set up Unbound and systemd-resolved on my Linux machines instead. The goal was to improve DNS resolution speed and security, but as you can probably guess, it wasn’t all smooth sailing.
[Read More]I’ve been using SSH for years, and one thing that’s always been a bit of a hassle is managing SSH keys and connections when working with multiple servers or jump hosts. That’s where SSH-Agent and key forwarding come in - they can simplify your SSH workflow and make it easier to access remote systems. In this article, I’ll cover how to use these features to improve your SSH experience.
[Read More]I’ve been running a homelab for years, and one thing I’ve learned is that managing background tasks is crucial. Whether it’s backups, video encoding, or other long-running tasks, they can quickly eat up system resources if not managed properly. That’s where nohup and ionice come in - two tools that have saved me a lot of headaches.
nohup is a simple yet powerful command that lets you run a process in the background, ignoring hangup signals. This means you can log out of your terminal without interrupting the process. To use nohup, just prefix your command with nohup and append an ampersand (&) at the end:
I’ve been there - your Linux system won’t boot, and you’re left staring at a black screen. This can happen due to a variety of reasons, such as a faulty kernel update, a corrupted boot loader, or even a simple mistake during system configuration. That’s where a USB rescue shell comes in - it can be a lifesaver. In this article, I’ll walk you through the process of recovering a borked Linux boot using a USB rescue shell and chroot.
[Read More]As someone who’s spent years running a homelab, I’ve found myself dealing with a multitude of background tasks on a daily basis. These tasks can range from simple scripts to complex services, all of which need to be managed and monitored. I’ve seen this go wrong when a task is left to run without proper management, so I’ve learned to rely on tools like screen and tmux to keep my tasks running. However, I’ve recently started using nohup and systemd to manage my background tasks, and I have to say, it’s been a game-changer.
I’ve spent years managing Linux systems, and I’ve learned that a well-configured fstab file is crucial for reliable mounts and easier disk management. In this article, I’ll share my experience with fstab, including practical examples, caveats, and troubleshooting notes to help you improve your Linux workflow.
The fstab file, typically located at /etc/fstab, is a configuration file that defines how disk partitions, block devices, and network shares are mounted on a Linux system. It’s a simple text file containing a list of entries, each representing a mount point. The general format of an fstab entry is:
As someone who’s spent years running Linux systems, I’ve learned that managing background jobs is crucial for maintaining system performance. Whether you’re running a homelab, self-hosting services, or just using your Linux machine for everyday tasks, it’s essential to keep resource-intensive jobs in check. In this article, I’ll dive into how to use nice and ionice to tame these jobs and keep your system responsive.
The nice command is a simple way to set the priority of a process. By default, Linux gives all processes a nice value of 0, which is normal priority. You can adjust this value using the nice command, with values ranging from -20 (highest priority) to 19 (lowest priority). To use nice, just prefix your command with the nice command and the desired nice value. For example:
