TCP CONNECT MODE
-p port_spec, --dest-port port_spec (Target ports)
This option specifies which ports you want to try to connect
to. It can be a single port, a comma-separated list of ports
(e.g. 80,443,8080), a range (e.g. 1-1023), and any
combination of those (e.g. 21-25,80,443,1024-2048). The
beginning and/or end values of a range may be omitted,
causing Nping to use 1 and 65535, respectively. So you can
specify -p- to target ports from 1 through 65535. Using port
zero is allowed if you specify it explicitly.
-g portnumber, --source-port portnumber (Spoof source port)
This option asks Nping to use the specified port as source
port for the TCP connections. Note that this might not work
on all systems or may require root privileges. Specified
value must be an integer in the range [0–65535].
