Introduction to DNS Resolution Issues

I’ve been running my own homelab for years, and like many of you, I’ve had my fair share of DNS resolution issues.

The goal was to improve DNS resolution speed and security, but as you can probably guess, it wasn’t all smooth sailing.

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.

As someone who’s spent years running a homelab, I’ve learned that managing background tasks can be a real challenge. You’ve got scripts and commands that need to keep running, even after you’ve logged out of your system. In my experience, nohup and systemd have been the two most useful tools for getting this done.

What is nohup?

nohup is a simple command that lets you run a process in the background, ignoring the SIGHUP signal that’s sent when the controlling terminal closes. This means you can start a process with nohup, log out, and the process will just keep on running. Here’s an example:
