Infomaniak Dynamic DNS Client

iddns is an easy-to-use dynamic DNS updater for the Infomaniak Dynamic DNS service written in bash.

Install

Make sure curl is available and installed on your system. make is also required if you want to use the Makefile for installing the script automatically.

Either clone or download this repository.

$ git clone https://github.com/nhedger/iddns
cd iddns
make install

Run make uninstall from the same directory if you want to completely remove iddns from your system.

Usage

iddns [options] HOSTNAME

Option	Expected value	Description
-s	None, it's a flag	Silences all output
-t	None, it's a flag	Prefixes all output with a timestamp. Useful when logging
-c	Path to configuration file	Custom configuration file. See below for more information
-u	Username	Dynamic DNS username, as configured in your Infomaniak Manager
-p	Password	Dynamic DNS password, as configured in your Infomaniak Manager
-i	IPv4 or IPv6	The IP address to update the Dynamic DNS record with
-g	URL	Custom API endpoint that returns only your public IP address as text-only
-v	None, it's a flag	Displays the version
HOSTNAME	Valid FQDN	The hostname for which the record must be updated

Using a configuration file

Sometimes, using a configuration file instead of exposing all your options on the command line is preferable. On such occasions you may pass the -c parameter followed by the path to your configuration file.

$ iddns -c /path/to/config/file example.tld

iddns will also try to load automatically a default configuration file named $HOME/.iddns if it exists and no alternative configuration file was passed on the command line.

Valid configuration options

Option	Expected value	Description
IDDNS_SILENT	true/false	Silences all output
IDDNS_TIMESTAMPS	true/false	Prefixes all output with a timestamp. Useful when logging
IDDNS_USERNAME	Username	Dynamic DNS username, as configured in your Infomaniak Manager
IDDNS_PASSWORD	Username	Dynamic DNS password, as configured in your Infomaniak Manager
IDDNS_IP	IPv4 or IPv6	The IP address to update the Dynamic DNS record with
IDDNS_GRABBER	URL	Custom API endpoint that returns only your public IP address as text-only

WARNING : Options declared on the command line have a higher priority so they will override any of these values when set.

You'll find a example configuration file in this repository.

Scheduling updates

You may automate your updates by setting up a cron job for iddns.

Create a configuration file that holds your credentials:

IDDNS_USERNAME="example"
IDDNS_PASSWORD="password"

Create a /etc/cron.d/iddns file with the following contents (replace with the path to your config file and hostname) :

0 * * * * root /usr/local/bin/iddns -t -c /path/to/config example.tld >> /var/log/iddns.log 2>&1

This will run iddns every hour and log its output to /var/log/iddns.log.
