Welcome @stoeps.de, the blog of Christoph Stoettner
I work at Vegard IT GmbH as a senior consultant with a focus on collaboration software, Kubernetes, security and automation. I mainly deal with HCL Connections, WebSphere Application Server, Kubernetes, Ansible, Terraform and Linux.
Sometimes my daily work results in technical talks and blog articles, which you can follow here more or less regularly. You can find the presentations in the main menu under public speaking .
I created a list of tools I use regularly, most of which have been released under an open source license.
In my spare time I read a lot, test all kinds of technical software and gadgets and try to follow about 200 RSS feeds. Here you can find a collection of them.
This is my private blog, all opinions are my own.

In late 2023, I started exploring immutable operating systems, specifically Fedora Silverblue and Bluefin . If you’re curious about why I made this switch and want more technical details, check out my Froscon Talk on ‘Next-Gen Desktops’ or watch the video presentation below.

I attended Chemnitzer Linuxtage 2025 from Friday, March 21st to Sunday, March 23rd. It was my second time at the event, and I enjoyed it even more than last year. This time, approximately 3,500 people attended in person, with up to 250 parallel viewers joining the live streaming of lectures. You can find more details in the official blog post .

The last weeks I had twice the issue of a huge homepage database with HCL Connections. Both systems weren’t installed by me, but I reviewed them.
So I know this issues quite well since I faced it the first time years ago. This always happens when you migrate Connections environments side-by-side, and you forget to remove the old search nodes.

I had some issues with PDF export functionality in HCL Connections the last weeks.
The server became unresponsive multiple times due to high load from PDF exports. To quickly address the issue, the simplest solution is to disable the PDF export feature by configuring the icxt.pdfexport.access.requiredrole property in the Resource Environment Entries.
This week, I investigated an issue with the advanced profiles search in HCL Connections. I had a system which did not show any results in the advanced search for the department number of Connections profiles.
HCL support tried for three months to reproduce the issue, and the users missed the option to search for their teammates with the advanced profiles search.
In the last blogpost I showed how I use an instance of changedetection.io on a Raspberry Pi to monitor and track changes in a ServiceNow portal.
Meanwhile, I tweaked this a bit more and found a way how I can monitor the RSS Feed of my blog to post a toot on mastodon when I created a new blog post.
