I have run the script on the Nagios server, and on the client system. When I ran the script on the server, the syntax I used was the following: /usr/local/nagios/libexec/check_nrpe -H hadron -c check_iptables The output of that command was: CHECK_NRPE: No output returned from daemon. I ran the script on the client using the following syntax: /usr/local/nrpe/libexec/check_iptables.sh The output of that command was: OK INPUT 20 rules<br>OK BLACKIN 497 rules<br>OK BLACKOUT 497 rules<br> When I ran the command on the client, I did so as the root user. The nagios user account exists on the client, but as a means of security it is set up with the /sbin/nologin shell. I confirmed with other administrators, as well as in practice, this should not intefere with operations. >> 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. I looked at the plugin, and I am not sure what the syntax is for entering the return codes. -----Original Message----- From: Assaf Flatto [mailto:nag...@flatto.net] Sent: Monday, January 17, 2011 4:24 PM To: Nagios Users List Subject: Re: [Nagios-users] CHECK_NRPE: No output returned with check_iptables.sh script Kaplan, Andrew H. wrote: > Hi there -- > > Thanks for your reply.

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.
