A site I work with uses PRTG for infrastructure monitoring and Zerto as part of the DR strategy. Unfortunately there are no native PRTG sensors available for monitoring Zerto.

This post is a little cheat sheet of common operations that I perform using OpenSSL.

A few years ago I was working on a project where we had to provide a reliable and high quality free to air broadcast signal to 70 TV’s for the Melbourne Cup. It ended up being quite complex with lots of AV and IT integration work being done however the important part of getting the signal to the TV’s reliably was done using MuMuDVB. This post will cover how to install and configure MuMuDVB on a Raspberry Pi 3.

I have worked on a variety of projects where a Raspberry Pi was the perfect hardware platform to host various services. They are very cheap, easy to configure, and there is a vast array of add on hardware available. This post will cover a basic installation of Ubuntu MATE 16.04.2 LTS onto a Raspberry Pi 3.

I like to use Raspberry Pis for a lot of my projects. Something I like to do is disable Bluetooth and WiFi as these are not generally things that I run on a server. There are probably a variety of ways to achieve this but this is how I do it.

I am a big fan of using Linux for various projects. There is a bit of a learning curve if you have only ever worked in the Windows or OS X worlds but Linux skills are definitely worth the time and effort to develop. This post will cover a basic installation of Ubuntu Server 16.04.2 LTS 64-bit.

Though most businesses these days are moving to cloud providers for their email services, there are still quite a lot of on premise installations of Exchange 2016 out there. When it comes time to apply Windows updates, upgrade your Exchange servers to the latest CU or just perform a reboot there is a procedure that you should follow to avoid disrupting client access.
