- Removed get_local_subnets() and scan_subnet() — no longer needed
- Added read_arp_cache() to read kernel ARP table from /proc/net/arp
- Added fallback to 'ip neigh show' if /proc/net/arp unavailable
- Added lookup_oui() to query system /usr/share/hwdata/oui.txt for vendor names
- Removed subprocess nmap call and re import (no longer needed)
- run() now directly reads ARP cache instead of scanning subnets
- Zero active network traffic — purely passive monitoring
- Removed sudo requirement
Parse nmap vendor name from MAC Address line (filtering out 'Unknown').
Fall back to socket.gethostbyaddr for IPs nmap didn't resolve a hostname
for. Alert label is now: 'hostname (vendor)' | 'hostname' | 'vendor' |
'unknown', in that priority order.
urllib's default Python-urllib user agent is flagged by Cloudflare Bot
Fight Mode (error 1010) when m.example.org homeserver sits behind
Cloudflare. Add a browser-like User-Agent to Matrix PUT/POST requests so
Cloudflare passes the traffic through.
