nmap

Nmap ("Network Mapper") is a free and open source  utility for network discovery and security auditing.

| Ubuntu manpage | cheat sheet |

Install nmap with CLI:

sudo apt install nmap

Scan network, list machines that respond to ping.

nmap -sP 192.168.0.0/24

Full TCP port scan using with service version detection - usually my first scan, I find T4 more accurate than T5 and still "pretty quick". Replace target with hostname or ip:

sudo nmap -p 1-65535 -sV -sS -T4 target

Scan port with TCP:

nmap -p 22 example.org

Scan port with UDP:

sudo nmap -sU -p 10001 192.168.0.1
