   nmap 7.94 (network scanner)

   Nmap (Network Mapper) is an open source utility for network
   exploration or security auditing. It was designed to rapidly scan
   large networks, although it works fine against single hosts. Nmap
   uses raw IP packets in novel ways to determine what hosts are
   available on the network, what services (ports) they are offering,
   what operating system (and OS version) they are running, what type
   of packet filters/firewalls are in use, and dozens of other
   characteristics.
