DLDNS - Dinamic Linode DNS

DLDNS - Dinamic Linode DNS

About

I created this simple tool to automatically update DNS entries for domains hosted at Linode. Uses Linode API v4 to update domain records to a specified target. It's used in combination with cron to update IPs after they change.

How to install it

Download or clone this project. Rename .env.example file to .env. Make sure you set the LINODE_PAT to your Linode personal access token. Don't forget to run composer install.

How to obtain a Personal Access Token

Sign into the new Linode Manager. Go to My Profile and API Tokens.

Create a new Personal Access Token. Make sure to provide proper access level for Domains.

Get the token and put it in .env file.

Usage instructions

helper-domains.php

This script shows a table with all your Linode domains:

php helper-domains.php

E.g.:

helper-records.php

Lists all the records from a domain. Requires the domain ID provided as argument: domain_id=123456.

php helper-records.php domain_id=123456

E.g.:

update-record.php

Updates the target for a specified record. Requires domain ID (domain_id=123456) and record ID (record_id=9876543) provided as arguments. Also a target IP (target_ip=1.1.1.1) argument is optional. If provided sets the record target to the argument value. Otherwise obtains the system's public IP address and uses it as target:

php update-record.php domain_id=123456 record_id=9876543
php update-record.php domain_id=123456 record_id=9876543 target_ip=123.234.211.211
