Metaname DNS Record Update Script

A small Python script to update a single A record on Metaname's servers. Configuration variables are loaded in from a local .env file, and a template service file for use with systemd is included.

Configuration

In order to configure the script, you may copy the .env.template file into .env and populate the fields within. Here's a breakdown of the variables:

Name	Description
ACCOUNT_REFERENCE	The 4 digit code used to uniquely identify a Metaname account.
API_KEY	The API key provided to you by Metaname.
RECORD_NAME	The name of the A record to be updated on Metaname.
LOGGING_FILE	The name of the file to log to.
IP_STORE_NAME	The name of the file to store the last known IP in.
DOMAIN_NAME	The domain whose DNS table is being updated.

Usage

Using the script is simple. You may run the script manually, or you can configure the script to run on boot via systemd. For either usage, passing the -s or --silent parameters suppresses logging.

Manual

To run the script manually, simply execute via the command line:

chmod +x metanameUpdateScript.py
./metanameUpdateScript.py

On Boot

If you wish to execute the script on boot alongside other systemd services, then you can use the metaname-update-script.service.template included in the repository. It looks like this:

[Unit]
Description=Updates Metaname DNS Record with Public IP
After=multi-user.target

[Service]
Type=idle
ExecStart=/usr/bin/python3 /path/to/script.py
WorkingDirectory=/path/to/
User=<user>

[Install]
WantedBy=multi-user.target

You're going to want to fill out /path/to/script.py with the absolute path on your machine to where the metanameUpdateScript.py script is located. You also need to replace <user> with the name of the user account who will be executing the service. Then, simply enable it like you would any other systemd service:

systemctl enable metaname-update-script
