Hi,

You can specify the port to use, in example NSClient++. Change the port=<portnumber> under the [NRPE] section in nsc.ini. NSClient will listen to the port you specified.

And when you issue the command ./check_nrpe -H <ipnumber> -p <portnumber> -c <command> it will connect to the port that you specify.

Hope this helps
