Adding a USB GPS Receiver to Direwolf to create an APRS Tracker

I recently posted a tutorial on Installing Direwolf on a Raspberry Pi to run an APRS node. The included direwolf.conf example assumed the node was operating as a static iGate or Digipeater, so the location (In Longitude and Latitude) was hard coded, however Direwolf also supports connecting to a GPS receiver for real time location tracking.

As I have a handheld radio with inbuilt GPS / APRS support I don't have an immediate need to use Direwolf as an APRS tracker, but curiosity got the better of me and I ordered a Cheap USB GPS receiver from Amazon (Apparently I ordered the last one, but any standard USB GPS receiver outputting NMEA formatted data should work). Its now up and running so I thought I'd document the processes.

APRS - Installing Direwolf 1.5 on a Raspberry Pi running Raspbian Lite

I've previously written a blog post about setting up an APRS Digipeater with a Tait 8105. Almost a year has passed since then and the latest release of Direwolf now natively supports the CM108 Sound Fobs, so we can ditch Hamlib. This makes configuration much simpler.

The following is a quick and dirty guide to getting Direwolf setup as a Digitpeater on Raspbian. For more detailed instructions on getting a Tait radio configured see the previous blog post.

Configuring Sendmail to use Amazon's Simple Email Service (SES)

Well it's been around 6 months since I last made a blog post - turns out babies are pretty time consuming.

I hate email server configuration with a passion so I offload what I can to Amazon's Simple Email Service or SES for short. This is a quick post guiding you how to get Sendmail to work with SES.

Disclaimer: I am by no means an email expert. The configuration below is working, but may not be optimal. Use at your own risk. That said, most of the configuration below was lifted straight from the AWS Docs so you'd hope that it would be reasonable.
