nmap is a powerful network scanner that provides port scanning, OS and service identification, and more.
After installing the package, nmap will be available at Diagnostics >
nmap as well as in the shell (SSH or Console).
The nmap package also installs an OUI database that is used by the pfSense® webGUI to display manufacturer names on pages that list MAC addresses, such as the :doc:`ARP Table </monitoring/arp-table>`, and :doc:`DHCP Leases </dhcp/dhcp-leases>`.
