external-ip-monitor

Monitors changes to external IP address. If the external IP has changed for a A Record specified in an environment variable DNSARECORD (e.g. example.com), then the address for that DNS A Record is changed at the OVH registry.

Login credentials to Ovh are stored in a file called ovh.conf located in the login directory of the user. This can be retrieved from example code from ovh .net client.
