Cloudflare

From cloudflare we need to generate an API token which we will use later for dynamicly update the our public IP for the A record for the selected domain

Create API token

Open cloudflare dashboard, go to the “API Tokens” section your Cloudflare profile to create a token.

Your new token needs to have:

• the Zone:DNS:Read permission (not automatically granted in the Write permission)
• the Zone:DNS:Write permission
• the “All zones from an account” scope

Save the token as you will need it in the following steps

Linux

Setup a basic linux server or vm, I will carry on with a debian setup

Install the latest version of ddclient

Run the following commands

2

apt update
apt install -y ddclient

Configuration

ddclient is controlled by ddclient.conf which we will need to modify

Update “$EMAIL”, “$PASSWORD” and “$HOST” in

“PASSWORD” is the API Token we generated before

/etc/ddclient.conf
