What is it?
netscanner is a terminal-based network scanner and diagnostic tool built in Rust with a text user interface. It lets you list hardware network interfaces, switch the active interface used for scanning and packet capture, and view nearby WiFi networks with signal strength charts.
For IPv4 networks, it pings a CIDR range and reports hostname, OUI vendor and MAC address for each host, scans TCP ports, and captures packets for TCP, UDP, ICMP and ARP, with start/pause control and log filtering. IPv6 packet dumping covers ICMPv6 only, and IPv6 scanning is listed as a pending TODO.
Scanned IPs, ports and packets can be exported to CSV, and the tool also counts traffic and looks up DNS records. It needs root privileges to run, and on Windows it requires Npcap.
Key features

Use cases
- Checking which devices are on a local subnet and identifying their vendors
- Inspecting WiFi signal strength when choosing a location or channel
- Debugging traffic on a host by capturing and filtering packets in a terminal
