Route53 Dynamic DNS

Route53 dynamic dns updater written in Python

If you are using Amazon's Route53 DNS Service and want to connect a box at home, this one is for you. The script will determine your current IP address and update your Route53 hosted zone record if necessary.

It will also create a new record if non exists under the hostename. If no hostename was configured it will by default use the systems hostname.

Dependencies

The updater is using the Boto project, a python interface to Amazon Web Services. Please download and install Boto from here: https://github.com/boto/boto

How to set it up

Clone it on your system:

git clone https://github.com/slot/r53dd

Configure AWS keys and hosted_zone etc. in r53dd/updater.cfg (see documentation inside file)

Alternatively this file can be placed under /etc/r53dd.
