"Nmap (Network Mapper) is a security scanner originally written by Gordon Lyon (also known by his pseudonym Fyodor Vaskovich) used to discover hosts and services on a computer network, thus creating a \"map\" of the network. To accomplish its goal, Nmap sends specially crafted packets to the target host and then analyzes the responses.The software provides a number of features for probing computer networks, including host discovery and service and operating system detection."@en . . . . . . .
