Nmap

Network scanner and host-discovery tool.

Nmap ("Network Mapper") probes a target host or network for open ports, running services, and operating-system fingerprints. It supports TCP, UDP, SCTP, and IP-protocol scanning, with a scripting engine (NSE) that extends it to vulnerability detection, service discovery, and protocol-specific probes.

It is one of the oldest and most widely used security tools on Linux and ships in every distribution's repositories.
