⁠dyndns53

Tool for updating your Amazon Route53 DNS A records to the current external IP of a running machine.

⁠Configuration

There are two configurations that are needed for this tool to work properly:

• AWS credentials which need to be provided via environment variables AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY. Make sure that you have access to modify the DNS records.
• A tool's configuration text file which needs to reside in ~/.dyndns53

⁠~/.dyndns53 configuration file

The configuration file should contain blocks of the following format:

[bar.com]
subdomains: foo
root: True

Each section is a domain. subdomains option need to include all the subdomains for which this tool will update the A record. The root option needs to be boolean and will determine if the tool will update the record for the root domain too.

Example:

[bar.com]
subdomains: foo www
root: True

[test.com]
root: True

The above configuration will update the A record of the following fully qualified domain names to the current external IP address:

• foo.bar.com
• www.bar.com⁠
• bar.com
• test.com
