# DynuIPRefresher
A lightweight C++ application to setup a service for refreshing a dynamic IP to the Dynu servers. 
Dynu.com is a free DDns service and provides an API.

## Installation
Download the latest Release at [Release_Page](https://github.com/Lukas-Heiligenbrunner/DynuIPRefresher/releases).
I'm providing executables for Debian/Ubuntu (.deb) and RHEL/Debian (.rpm). 
But you can still compile the code my your own (see build section).

## Configuration
There is a configuration file `/etc/iprefresher.cfg` where you have to specify the DYNU API key (get it from their homepage), the domainid and your domain.
Furthermore, you can optionally specify a Telegram API key and a Chat ID if you want to be notfied when your local ip changes.
