An Article about Rubenshof - Linux Mint Unattended Installer

Every year we set up some devices for our students at school. This year we had the situation of delayed deliveries, because a donation of notebooks took longer than expected. So we have to get faster with setting the devices up. I took this challenge and created a unattended Workstation setup for our school.

Virtualized School IT Lab

This Lab environment was created for a showcase at a local school. The school, a small community-driven institution based on Montessori principles, serves approximately 70 children and teachers. Open Source and Free and Open-Source Software (FOSS) are valued by some of the teaching staff, and they requested assistance with certain aspects of the school’s infrastructure. Considering this preference, a cloud solution was deemed unsuitable.

Important Note: This is solely a LAB environment and should not be used for production purposes. It lacks critical security measures, including data protection, backups, encryption, network isolation, and other essential elements required for production environments. This lab is intended for demonstration and educational purposes only.

Use the power of automation

I really like to automate things. So I also automate the creation and provision of base images for a datacenter environment.

There are some tools which solve this. In my case I prefer packer.io.

Why? Because it is opensource, supports a lot of different technologies, runs on different platforms and so on and so on. And it is simple and lightweight.

So with packer you can, build and provision images in cloud environments but also local with kvm, virtualbox or even hyper-v.

Get Fibre Channel HBA adapter metrics

Since I deal with Fibre Channel, I have to deal with new tools as well. Today for example we had some issues on a Linux Server with Fibre Channel HBA setup. In fiber optic network you are looking for Rx/Tx power metrics, which I also get from the SAN switches. But to detect issues it’s good to see the RX/TX power also from the host side. The Linux support inside the company told me, that they can’t find metrics inside the system. So I tried to get some more knowledge about that topic.
