Show HN: NetSentinel – a local network security scanner and connectivity monitor

A Google Nest speaker was winning the STP root bridge election on my network and knocking out DNS every 45 seconds. Took five separate tools to find it.

I started NetSentinel one Sunday afternoon out of frustration. Thought I would be done the same evening. But I was off by about 2 months. Every time I hit a problem that lived in yet another tool, I just added it.

Available on Windows (MS Store), macOS and Linux.

Testers with different HW are welcome.
