OpenVPN comes with example-scripts to update /etc/resolv.conf using "resolvconf" or systemd-resolvconf. I don't use one of them therefore I modified the script so that it simply changes /etc/resolv.conf directly. I placed a variable "IMMUTEABLE" in this script. If IMMUTEABLE is set to 1, this script will change the fileattribute of /etc/resolv.conf to immuteable. In that way it is possible to prevent other programms like dhcp-clients to change /etc/resolv.conf while openvpn is running.
This year I want to send you merry christmas by creating a blog-entry for a raspberry pi christmas project. The "christmas-machine" displays merry christmas and wishes for the "christkind" on a tft display for the raspberry. It is possible to send christmas wishes using a web applications that can be accessed via wifi. I placed this installation at the coffee-kitchen in the office and it was very nice to see that my colleges had a lot of fun with it.
Blesses for "Brother Patrick" who spent me that wonderful Joy-IT TFT display.

I started this blog five years ago. In the beginning I wrote mostly articles about sysadmin and programming. Now its also filled with security related stuff. It's fascinating for me to have a history of my interests. It's sadly that my spare time got rare and so it happens that I don't write much lately. My intention for the next 5 years is, to be more consequent with writing articles.
