Windows Console App to allow dynamic updates to a DNS entry in Linode.
.NET Framework 4.5.2+
Open a command prompt and run the executable with the parameter "setup" to go through an initial setup process.
LinodeDynamicDns.exe setup
There is no validation, so don't goof around.
This will write the settings to the file settings.json for later reference.
After the initial setup has been done, simply run the executable to update the DNS to point to the IP of the machine you're running it from.
I would suggest to use Windows Task Scheduler to have this executable run on a schedule.
