Some time ago I asked my self the question if it is better to kickstart systems or working with ESX templates when deploying RHEL as ESX guests.

This brought me to the idea to test the OTRS change management module in order to propose OTRS as a replacement for the currently used software for the Change- Incident- and Problem Management. Incident- and Change Management integration I ….Read More
Lets celebrate 25 years of DNS
Today, we can celebrate 25 years of DNS. Can we really celebrate? Is the age of /etc/hosts really over? No, /etc/hosts will last for ever. Why?

Thanks! Thanks to all those people that designed and operated DNS until today and in ….Read More
