About

Quick about me

My name is Johnny. I am a person in a good mood and do not take myself too seriously. I like talking to people and can from time to time be considered talkative. My humor may not be considered good, but then it does not take much to make me laugh.

I've always been the person who likes to disassemble things to see how they work. Over the years, I have improved and at times manage to repair things that have stopped working.

More about me

Interests

It can be said that I am above average interested in technology. At home I have two small racks with a mix of single board computer's, PC and network equipment. Here I run assorted services and programs I want to test or improve myself on.

Programming is also something I am interested in. Python is the language I am most interested in. Some of the reasons are that it can be used for everything from simple sensor and motor control to machine learning and everything in between. I have used it mostly on Raspberry PI and nodemcu (ESP32 and similar). I have also used Arduino a bit but have prioritized other things over this.

I also like being able to work with my hands. Whether it is a small project where I solder and put something together or work on a car.

Technology

On the computers I have I am running Proxmox and ESXI. These are operating systems designed to run virtual machines stably and without consuming many resources. They fall under the category of type 1 hypervisor. On these machines I virtualize several services.

I have ESXI mostly to keep up to date on it. Here I try a little different from time to time to see what is different from Proxmox.

What I use most is Proxmox which is a real joy to work with. Here I have virtual machines of Linux and Windows running. I have also set up my "gaming" PC with Proxmox. Should I want to play something, I have passed the video card to a virtual Windows 10 installation. It was not used much for gaming and needed to be reinstalled, so I thought why not.

Services and operating system locally

• Proxmox Virtual Environment: For virtualization.
• Proxmox Backup Server: To back up all virtual machines I do not want to lose.
• VMware ESXI: For virtualization.
• pfSense: Router for own server lan.
• Windows server 2019: For those who do not work on Linux.
• Windows 10: Nice to have.
• Ubuntu client: Also, nice to have.
• Ubuntu server: I have several of these for different tasks such as web server and Docker. Okay not to have everything on one machine when I destroy something.
• Kemp loadmaster: I use this for the reverse proxy functionality.
• Kubernetes (k3s): This is on a Raspberry PI cluster.
• Openmediavault: For NFS storage.
• GNS3: So that I can play with networks without having a lot of equipment physically available.
• Ranches: To manage the cubes (k3s) and Docker.
• Portainer: Docker on a Raspberry pi.
• 3CX pbx: I set this up since I had access to some Cisco phones and wanted to see if I made them work. It works, but only locally online at home.
• Iperf3: Fun to test local speeds.

Services and operating system External

• Oracle Linux 8.5: To practice on a branch of Red Hat Linux.
• Ubuntu server: Various testing.
• Plex: Movies and series.
• Kasm: For the ability to open insecure pages and files without being afraid of viruses.
• Proxmox Virtual Environment: Set up with someone with fiber to run some services.
• Apache web server: This page.

Career

Current

Today I am currently a system administrator at a high school in Viken. The days are spent on some user support, but also project work in modernization and new construction. My tasks also involve making sure that AV and IT systems work as they should. Where I have time, I try to be proactive and make sure that equipment and rooms are being updated before there are any problems. I am also the supervisor for the apprentices we have in IT. This is something that is incredibly fun when things are going well but can also be time-consuming.

Where we previously used Active Directory, we now use Azure Active Directory to manage all teachers and students. For managing PCs, Microsoft Intune is used in the backend of an internally developed tool.

Being a system administrator at a high school in Viken can be compared to being deployed with a customer. We have a central department we can turn to, but then there are usually bigger things or if something must be done in a system we do not have access to.

Previous experience

I had a short trip to TDC (now absorbed into Telia) where I worked with setup, configuration and network cleanup. The equipment I worked with here were Cisco switches and routers as well as some Juniper.

Before TDC, I was an IT consultant at Datametrix (now absorbed into Telenor). In the years I worked at Datametrix, I have been able to work with a lot of different assignments. From small assignments to replace a device to month-long projects to replace entire systems in both network and telephony. Telephony quickly became smaller, but fun to have come across. The time I worked in telephony is the time I traveled the most, but there was also traveling on network projects. I traveled mostly around in Scandinavia, but I have also been to India to assist. I worked with a lot of different things over the years I was in Datametrix and will not list everything, but I was in two primary areas:

• In networking, I worked with Cisco switches and routers.
• Telephony also worked in Cisco, but this also included some work on Windows server and VMware ESXI.
