install the ddclient to update dynamic DNS


sudo apt-get update

sudo apt-get install ddclient libjson-any-perl libdata-validate-ip-perl

wget https://files.pimylifeup.com/portforwarding/ddclient-3.9.0.tar.gz tar -zxvf ddclient-3.9.0.tar.gz

sudo cp -f ddclient-3.9.0/ddclient /usr/sbin/ddclient

sudo mkdir /etc/ddclient

sudo mv /etc/ddclient.conf /etc/ddclient

sudo nano /etc/ddclient/ddclient.conf

Add the following to below the commented header in the file, also remove anything else in the file. We will add more to the file later on with our guides on using No-IP or Cloudflare.

use=web, web=checkip.dyndns.com/, web-skip='IP Address' ssl=yes


NO-IP offers free subdomains

CloudFlare you need to own a domain name

Cloudflare also offers more protection such as free SSL anonymized IP DDOS protection



protocol=cloudflare

server=api.cloudflare.com/client/v4

login=your_email

password=your_api-key

zone=your_domain.com


anything.your_domain.com


sudo /etc/init.d/ddclient restart

You may need to turn off the Cloudflare proxy


Running ddclient as a Daemon


sudo nano /etc/default/ddclient

run_daemon="true"

run_dhclient="false"

run_ipup="false"


sudo service ddclient start


sudo service ddclient status

sudo nano /etc/cron.weekly/ddclient

  1. !/bin/sh

/usr/sbin/ddclient -force


sudo chmod +x /etc/cron.weekly/ddclient
