About Me

Thomas Preissler

My name is Thomas Preißler [praɪslɐ] and I was born in Germany some years back. I worked in Germany as a sysadmin then relocated to UK. I have run all sorts of standard services on a number of different Linux distributions.

I don't shy away from a challenge, because I want to learn something new and widen my horizon. This blog is an attempt of documenting my own development, understanding and experiences with various bleeding-edge technologies, e.g. IPv6 or DNSSEC. The underlaying server is also my playground for trying out new technology, new security paradigms and standards.

Please share with me your experiences or ask questions on a number of topics.
