Cf Ddns.sh Save

A simple client for automatically updating CloudFlare DNS with your current IP address

Project README

cf-ddns.sh

cf-ddns.sh is a minimal, easy to use DDNS client for automatically updating CloudFlare's DNS service to point to your current IP. It was written with portability in mind, so it will run in most POSIX-like shells. (BASH, BusyBox, etc.) It can even work on many embedded systems, like consumer-grade routers.

cf-ddns.sh is based on v4 of the CloudFlare API.

Prerequisites

  • POSIX-ish environment (Linux, OS X, BSD, etc.)
  • curl (requires HTTPS support)

Install

Download to your system and create a cron job to run the script with your parameters on an interval.

cf-ddns.sh [OPTION] -e=EMAIL -a=APIKEY -z=ZONENAME -r=RECORDNAME
