Providing a dual stack service behind a native ipv6 and carrier-grade NAT ISP
Monday, May 1, 2017
Suppose, you have an ISP that provides you with native ipv6 connectivity. This means, you have
been assigned a globally routeable IP version 6 address -yay!! However, this comes with a cost:

Using DisplayLink with Dell D3100 dock and Intel Sky Lake Graphics card on Debian
Monday, September 26, 2016
Getting DisplayLink to work on a fresh installed Debian testing took more time than expected.
One reason for this was for sure my lack of knowledge about the output providers infrastructure

After upgrade to Ubuntu 16.04 it still was working, but the internal sound card of my system wasn’t - and
sometimes the soundcard of my docking station only was working after a replug. That was the situation,
where I thought: A reinstall of the system would be great - and I simply choose Debian, it usually works.
