About

Check the DNS Record matches the current IP and alert when it's not.

Getting Started

Prerequisites

• pfsense 2.7.2
• Uptime Kuma

In Uptime Kuma create a Push Monitor and note the Push URL.

Installation

Download script to your pfsense home directory

wget https://github.com/hhanzo1/check-tunnel/blob/main/check-ddns-record.sh
chmod +x check-ddns-record.sh

Replace the domain in the BASE_URL and DOMAIN.

Usage

Test the script is running as expected by running manually, then scheduled via cron.

Enable the check script

# Run every hour

If the Push URL does not receive a HTTP request within Heart Beat internal (default 60 seconds), an alert can be triggered.
