DynDNS

Exceedingly stupidly simple script to run inside your network to keep your home-hosted site online when your ISP changes your IP for some reason.

Setup

Create an IAM user in the AWS console with at least { "Effect": "Allow", "Action": "route53:ChangeResourceRecordSets" } permissions, and create an access key, then:

cp example.envrc .envrc
${EDITOR:-nano} .envrc  # Fill in your details here.

Running

./src/main.py

This will grab the IP you're currently on from ifconfig.co, and set it as the A records specified in your environment variables, then exit.

Installation.

Install python and python-virtualenv.

Assuming you have systemd, run

cd /path/to/which/to/install/
git clone [email protected]:Asday/dyndns.git
make install

If you don't have systemd, run

cd /path/to/which/to/install/
git clone [email protected]:Asday/dyndns.git
make

Then figure out how to run src/main.py with the virtual environment on your own.
