Hi, I’m Stefan Thierolf and this is my web site. I’m an IT specialist system integration (Fachinformatiker Systemintegration) and work as Global IT Analyst - Network for a global automotive supplier. I lived in the United States (New Hampshire) for about five years and moved back to good old Germany end-of-2018.

I like to blog about Information Technology, Network, Linux and Security, therefore most of my blog posts are of “technical” nature.

I’m building networks for more than 20 years. With networks I mean computer networks. In most cases I’m dealing with Cisco hardware like switches, wireless controller and access points as well firewalls. And I’m doing other things like looking for innovations and IT security. I’m also writing technical documents and guides. Sometimes I develop source code and smaller software projects - So I might be a something like a devop - But I prefer to call it “automate things”…

Some of my interests:

  • Cisco (Switches, Router, Firewalls, Wireless)

  • Linux and Unix

  • Digital Model railroads

  • Reading (mostly IT books)

  • E-Sports (Skyrim, Fallout, Gothic, Risen)

Some of my certifications:

I’m running the domain thierolf.org and love the free internet. Therefore I am not on the typical US social networks.

German laws demand to have an Impressum (imprint) on a web site.

I have a DSGVO (german) and a GDPR (english) on my web site.

Feel free to take a look in my website history
