Welcome to my personal web site. Here you’ll find useful information and resources that I’ve written over the years.

I am an IT Consultant working in the Auckland, New Zealand, area with a passionate interest in all things relating to Networks and Security. I also do a lot with Linux, Virtualisation, and Cloud systems during my day job. You’ll also find a few odds and ends here relating to other things that I’m doing such as flying small airplanes when time and the weather permit.

Note that I’m still working on some of the content for this site – it’s actually a complete rebuild of the old site which was manually coded HTML. I’m still importing stuff from the old site such as the Logsurfer info and the aviation check lists. Please bear with me for the next couple of weeks – or let me know if there’s something missing that you’re looking for.
