Some time ago, I started to set up the “Network UPS Tools” (NUT) for my uninterruptible power supply (UPS) “Eaton 3S”. It’s a UPS which can be connected to a computer via USB cable.
I found a NUT-package in the “testing”-repository of “Alpine Linux”. Unfortunately, I was unable to create a working setup using this package. After some research, I found the reason for my problems: A missing dependency to the
hidapi-package. I wanted to submit a merge request to get around the problem permanently.

I bought an “Eaton 3S” uninterruptible power supply (UPS) some time ago. It is supposed to support my servers with power in case of a power loss. I also wanted to get notified about those “power down” events, so I looked for an open-source software to monitor the UPS hardware. I found the “Network UPS Tools” (NUT). In this article, I describe some of the pitfalls I came across.

I have been used to have a server running under my desk for years now. It serves “Nextcloud” for internal data sharing and “GitLab CE” for hosting my internal “git” repositories. Unfortunately this year was quite a hot one in terms of temperature. I was forced to shutdown the server multiple times due to the heat in my home office. As a result I started a research in order to find a solution about how to setup a much smaller system which does not heat up the room that much. This article describes my search to get it up and running with “Alpine Linux” in “diskless mode”.
