Homelab

What's actually running at my place

This isn't a theory showcase — these are services I set up myself, that throw real errors I have to fix. That's exactly where I learn the most.

Running

Proxmox Cluster

Several nodes running VMs and LXC containers. My virtualization playground — every other service in the home lab starts life here.

  • Proxmox VE
  • QEMU/KVM
  • LXC
Running

Monitoring with Checkmk

Watches services, network interfaces, and system time — and emails me the moment something's wrong. It's caught real problems before I ever noticed them myself.

  • Checkmk
  • SMTP alerts
Running

My own DNS zone & filtering

BIND9 answers for my internal zone, Pi-hole filters ads across the whole network — plus a wildcard TLS certificate of my own.

  • BIND9
  • Pi-hole
  • TLS
Running

Internal mail relay

Postfix and Dovecot deliver system and monitoring messages internally — so alerts never disappear into thin air.

  • Postfix
  • Dovecot
  • msmtp
Running

Automation with Ansible

Recurring tasks run as playbooks, keeping configuration consistent across every host — no more typing the same thing by hand on each machine.

  • Ansible
  • SSH keys
  • Inventory
Repo

Subnetting calculator

A small Python tool for practicing IPv4 subnetting — built because I needed it myself while studying.

  • Python
