nmap Nmap is an open source program that is used to perform port tracing written originally. ===

There will be several tools that allow us to know the reachable devices on our local network.

nmap

nmap it's a program open source which is used to carry out port sniffing originally written by Gordon Lyon (better known by his alias Fyodor Vaskovich). It is used to evaluate the security of computer systems, as well as to discover services or servers on a computer network.
