# nmap
|
|
|
|
> Network exploration tool and security / port scanner.
|
|
> Some features only activate when Nmap is run with privileges.
|
|
|
|
- Try to determine whether the specified hosts are up and what are their names.
|
|
|
|
`nmap -sn {{ip_or_hostname}} {{optional_another_address}}`
|
|
|
|
- Like above, but also run a default 1000-port TCP scan if host seems up.
|
|
|
|
`nmap {{ip_or_hostname}} {{optional_another_address}}`
|
|
|
|
- Also enable service detection, OS fingerprinting and traceroute.
|
|
|
|
`nmap -A {{address_or_addresses}}`
|
|
|
|
- Assume good network connection and speed up execution:
|
|
|
|
`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}}`
|
