The service discovery feature, also known as service scan, quickly detects active TCP services on a target host or network. Service discovery also gives its best with Ethernet-based networks, where TCP SYN scan technique can be applied to audit active services on any host in a few seconds.
You can scan a local or remote host but also entire networks. You may specify a maximum number of ports for the scan to make it faster:
<cmd> -s 192.168.1.1 # (single host)
<cmd> -s 192.168.1.1 -m 1000 # (single host with max ports)
<cmd> -s www.fing.io # (domain)
<cmd> -s www.google.com/24 # (entire network)
By default discovered services are reported on console as a plain text output, but you can choose between different output formats: like text, CSV, XML and HTML. So it is actually possible not only to use it as a command line administrative tool, but also integrated with your 3rd party applications.
