pfSense Authentication Monitoring System – Get Login Alerts via Email (Gotify Optional)
Hey folks!

I just released a lightweight monitoring solution for pfSense authentication events:
pfSense Authentication Monitoring System

Features:
Tracks successful and failed login attempts

Sends email notifications using pfSense’s built-in SMTP system

Optional: Sends Gotify push notifications if configured

Avoids duplicate alerts by tracking processed log entries

Easy to customize and set up

️ How it works:
A shell script scans /var/log/auth.log for new login entries

When an event is detected, it sends an email (and Gotify message if configured)

Can be run every few minutes using a cron job

Requirements:
pfSense with shell access

SMTP settings configured under System > Advanced > Notifications

Optional: Gotify server for push alerts

️ Installation:
Drop in two simple shell scripts, set a cron job, and you’re good to go.
