LAN Device Scanner

LAN Device Scanner is a Linux alternative to Advanced IP Scanner. It discovers
the devices on your local network using real network probes and shows their IP,
MAC address, host names and open services.

FEATURES (all implemented with real sockets, no sample data):
• Auto-detects your local subnets from /proc/net/route and the interface addresses
• Parallel discovery: unprivileged ICMP echo (when the kernel allows it), non-blocking
TCP connect probes on configurable ports, plus the kernel ARP cache for MAC addresses
(also finds hosts that drop every probe but answer ARP)
• Names: reverse DNS, NetBIOS name table query (UDP 137) and mDNS unicast PTR query
• Services: HTTP/HTTPS page titles and Server header, SSH/FTP/Telnet/SMTP banners,
SMB 445, RDP 3389 and other open TCP ports
• MAC vendor names are shown only when a real IEEE OUI file exists on the host
(e.g. the ieee-data package); no built-in vendor list
• Favourites with live re-check, Wake-on-LAN magic packets, CSV export
• Open a device in the browser (http/https) or the file manager (smb://) via xdg-open
• Interfaces, routing table and ARP/neighbour cache viewer

NOTES: ICMP ping needs net.ipv4.pinggrouprange to include your group (default on
Ubuntu); otherwise TCP + ARP discovery is used. Opening smb:// links depends on the
desktop's URL handler; the link is always copied to the clipboard.
