If you’ve got a desktop 3D printer, there’s an excellent chance you’ve heard of OctoPrint. This web front-end, usually running on a Raspberry Pi, allows you to monitor and control the printer over the network from any device that has a browser. But what if you’ve got two printers? Or …read more

I’m running Arch Linux on a desktop. I am not using Kerberos or Microsoft NTLM. sshd_config has this option set:
GSSAPIAuthentication no
I am not sure why the gssproxy.service is active or why it was started, but it is sta… Continue reading Can I disable GSSAPI Proxy Daemon without consequences? (Linux desktop)
Home directories have been a fundamental part on any Unixy system since day one. They’re such a basic element, we usually don’t give them much thought. And why would we? From a low level point of view, whatever location $HOME is pointing to, is a directory just like any other …read more

Getting a home music streaming system off the ground is typically a straightforward task. Using Apple devices with Airplay makes this task trivial, but if you’re a computing purist like [Connor] who runs a Linux machine and wants to keep it light on extra packages, the task gets complicated quickly. …read more

In an earlier installment of Linux Fu, I mentioned how you can use inotifywait to efficiently watch for file system changes. The comments had a lot of alternative ways to do the same job, which is great. But there was one very easy-to-use tool that didn’t show up, so I wanted to talk about it. That tool is entr. It isn’t as versatile, but it is easy to use and covers a lot of common use cases where you want some action to occur when a file changes.
The program is dead simple. It reads a list of file …read more
Security researchers have discovered three vulnerabilities in Systemd, a popular init system and service manager for most Linux operating systems, that could allow unprivileged local attackers or malicious programs to gain root access on the targeted s… Continue reading New Systemd Privilege Escalation Flaws Affect Most Linux Distributions
If you started using GNU/Linux in the last 10 years or so, there’s a very good chance your first distribution was Ubuntu. But despite what you may have heard on some of the elitist Linux message boards and communities out there, there’s nothing wrong with that.

If you would rather take the “easy” route, who is anyone else to judge?
Having said that, such options have not always …read more
