Abstract: You wish to configure your Raspberry Pi (Wheezy or Jessie) so that it automatically connects to different wireless networks.

So, you decided to start with an Raspberry Pi. For example for a small Nagios monitoring server. This short howto will explain you how to start with  Raspberry Pi.

Abstract: This short howto explains how you can install a very basic Debian (jessie) installation on VMWare (e.g. Workstation, ESXi, ...).

If you wish to implement a own DNS blacklist (e.g. because you wish to import one from the lists you found), then this could be build for some users (not a big company) based on an Raspberry PI. Setting them up required only 15 minutes.
