Since 2009 I’ve been working as a systems administrator. My primary focus is maintaining a secure infrastructure for a small radio and tv broadcaster. During my work I come across small and larger challenges in very broad field of interest. These challenges require solutions. I use this blog to keep track of my notes solving those challenges. I do not pretend all my posts contain original content. I did my fair share of searching the internet for a decent solution. If I failed to provide a reference and you think one is in order, please let me know.
