Profile

Hi HN!I'm excited to share a project I’ve been working on: *BroadcastDetector* – a lightweight tool for real-time detection of *switch loops*, *network loops*, *ARP spoofing*, and *broadcast storms*.It passively analyzes your network for unusual patterns using `tcpdump` and `pyshark`, identifies loops and spoofing attacks, and alerts you before they cause real damage.Key features: - Detects broadcast storms and switch/network loops - Monitors and alerts on ARP spoofing activity - Logs events to CSV (MAC, VLAN, timestamp, etc.) - Web dashboard for live traffic & alerts - Designed for Linux, optimized for Raspberry Pi 4/5 - Runs fully local – no cloud, no external APIUse cases: - Homelabs & da

BroadcastDetector – Detect Network Loops and ARP Spoofing in Real-Time is positioned in show hn launch, a segment that rewards a clear, focused offering.

The company is listed at the Show HN launch stage of development.
