# nmap
> Network exploration tool and security / port scanner
> Network exploration tool and security / port scanner.
> Some features only activate when Nmap is run with privileges.
- scan open ports of a single host
- Try to determine whether the specified hosts are up and what are their names.
`nmap {{192.168.0.1}}`
`nmap -sn {{ip_or_hostname}} {{optional_another_address}}`
- discover hosts in the 192.168.0.X area (no port scan)
- Like above, but also run a default 1000-port TCP scan if host seems up.
`nmap -sn {{192.168.0.1/24}}`
`nmap {{ip_or_hostname}} {{optional_another_address}}`
- faster scan of a single host (scans for common ports)
- Also enable service detection, OS fingerprinting and traceroute.
`nmap -F {{192.168.0.1}}`
`nmap -A {{address_or_addresses}}`
- faster scan of a subnet (scans for common ports)
- Assume good network connection and speed up execution:
`nmap -F {{192.168.0.1/24}}`
`nmap -T4 {{address_or_addresses}}`
- Scan a specific list of ports (use -p- for all ports 1-65535)
`nmap -p {{port1,port2,...,portN}} {{address_or_addresses}}`
- Perform TCP and UDP scanning (use -sU for UDP only, -sZ for SCTP, -sO for IP):
`nmap -sSU {{address_or_addresses}}`
