Puppet: Dipping my toes in the water

A need has arisen to get to grips with Puppet, a configuration management tool aimed at simplifying the management of large clusters of servers by creating a 'template' that's then applied to multiple devices, rather than making configuration changes manually to each server.

The tutorial below is heavily drawn from Melissa Anderson's Digital Ocean tutorial here, but I tend to find writing something down helps it stick, so here goes.


A Raspberry Pi Based ADS-B receiver (Aeroplane Tracker)

I recently purchased a 868/916 MHz Antenna which allegedly has a frequency range of 800 - 2500 Mhz. It's my intention to use this with a UKHASnet node, but this will require some planning and construction.  Rather than waiting I thought I'd put it to use, and some members of the London Hack Space have been playing with PiAware, a software image that allows a Raspberry Pi and RTL-SDR dongle to receive ADS-B  location data from Aeroplanes and forward it to, a popular site for viewing live Aeroplane locations and additional information.

As I had all the required bits, I thought I'd give it a go.
