Announcing Libero GNU/Linux 1.1 - A New Admin CD Release
I'm excited to share the release of Libero GNU/Linux version 1.1, a specialized i486 Admin CD built on Gentoo Linux foundations. This release represents months of development focused on creating a lightweight, powerful administration and installation environment.

Server monitoring 101
I have been running a @yunohost server for ~5 years now, but there is one question I have never been able to answer: how loaded is my server? 👀
I know, I am a terrible sysad (actually, I am not a sysad, at all), because I have no idea how to determine:
- if my server is running smoothly
- if the server is under stress, and why
- what applications are the heaviest
- if there is the possibility of installing more apps
- when peaks of stress are happening and what is causing them
In general, I would like to understand the fundamentals of server monitoring: what are the most critical metrics and what do they mean? What parameters do I have to keep an eye on?
I installed Prometheus and Grafana, but then I realized I have absolutely no idea what to do next… Do you have any suggestions?
I thought about watching some video tutorials, but I would not really know how they would relate to YunoHost installations.
Please, if possible reply in this thread of the YunoHost forum, so that we can keep track of this useful information also for others in the future. 🌻
Once I will have learned the basics, I would be very happy to write some pointers about this in the documentation, or an essential YunoHost Monitoring tutorial.

Evi Nemeth - Just learned in 2013 she (and six others) disappeared while traversing the Tasman Sea in a vintage yacht 🤯
Knew she had retired to her boating life, but had not heard about the disappearance. Rest in Power 🌟
The green Linux Administration Handbook was (still is?) a wonderful resource

Control groups, SSH, and magic attention keys are the go-to items here.
But add to them: TUI log-on on a third kernel virtual terminal (or terminal log-on on a serial or parallel port for maximum street cred), OOM score adjustments, and something that simply logs process statistics at regular intervals so that you can do some post-restart analysis.

Fehler „Operation not permitted“ beim Bearbeiten von resolv.conf. Eine Lösung.
Einige von uns haben sicher schon mal versucht, manuell DNS-Server auf einem Linux-System zu setzen – zum Beispiel in der Datei /etc/resolv.conf. Das klingt erstmal einfach: reinschreiben...
