`nmap` - Port Scans
|
|
-------------------
|
|
|
|
`nmap` is designed to allow system administrators to scan large
|
|
networks, to determine which hosts are up and what services they
|
|
offer. You can use nmap to test your firewall settings, for example,
|
|
to see if the required ports are open.
|
|
|
|
