What this skill does
Network Scanner Discover and identify devices on local or remote networks using nmap. Gathers IP addresses, hostnames (via reverse DNS), MAC addresses, and vendor identification. Requirements nmap - Network scanning (apt install nmap or brew install nmap) dig - DNS lookups (usually pre-installed) sudo access recommended for MAC address discovery Quick Start Configuration Configure named networks in ~/.config/network-scanner/networks.json: Then scan by name: Commands Output Formats Markdown (default): JSON (--json): Use Cases Device inventory: Keep track of all devices on your network Security audits: Identify unknown devices Documentation: Generate network maps for documentation Automation: Integrate with home automation to detect device presence Tips Use sudo for accurate MAC address detection (nmap needs privileges for ARP) Configure your local DNS server for better hostname resolution Add to cron or heartbeat for daily inventory updates Extend MACVENDORS in the script for better device identification
