Are all your NRPE clients going to be using port 5669? If so, you could edit commands.cfg and add the parameter "-p 5669" to the check_nrpe command. If you have a mixture of clients using port 5666 and 5669, then I would suggest updating the command to use something like "-p $ARG2$" and you would then modify the service's definition to specify the port. Check out https://assets.nagios.com/downloads/nag ... e/NRPE.pdf starting on page 8 for examples.

thank you
