This is still under construction, sorry! I started this website with articles in german only, my legacy website was written in german and english back then. The articles will be translated over time, currently I am busy with stuff like:

  • debops
  • ansible
  • OpenLDAP
  • PKI, OpenSSL
  • Icinga 2, Icinga Director
  • Graylog
  • Prometheus Monitoring, Grafana
  • Nextcloud
  • pfsense (CARP HA)
  • Samba
  • Debian 11
  • Amanda Backup
  • packer
  • … and way more

I offer support, online and offline, for all of this, my expertise of nearly 30 years with Linux and other technologies might help you and your business to improve and secure your IT as well!

Feel free to contact me, I am looking forward to it …
