When you run it manually - how do you do it ? check_nrpe -H <host> -c
check_iptables from the nagios server ? or local on the client ?
If you have not put in return codes how do you expect nagios to know
what was the exit status of the script ? how will it know if it finished
running or failed - those are not covered from NRPE but determined in
the plugin.
