This will make it work but will most likely also make it possible to query the host from any other server on the network. -- Andreas Ericsson [EMAIL PROTECTED] OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 - Take Surveys.

[Nagios-users] Return Code 127
I am attempting to monitor a remote HP-UX 11.11 client but I am confronted with the following error message: Return code of 127 is out of bounds - plugin may be missing. The log files add the following: Make sure the plugin you're trying to run actually exists. I checked the nrpe.cfg file on the remote client, and the check commands do have the complete path to the plugins. I manually ran one of the commands to confirm it could run. I then went to the Nagios server and verified the check_nrpe plugin was in the same directory as the others. I noticed that I could not start the nrpe daemon as root, but I was able to do so as a sudo user. The version of nagios I am running is version 2.6. While the nrpe client on the remote host and the check_nrpe plugin on the server are 2.5.1. What do I need to do to correct this? Thanks. - Take Surveys. Earn Cash.

Re: [Nagios-users] Return Code 127
I checked that out and I confirmed that the nagios user could execute the plugin by manually running check_nrpe by itself and getting the help information printed onscreen. I confirmed the permissions on the file were 775, while the user and group owners are nagios:nagios. The location of the directory for the plugin is /usr/lib/nagios/plugins, and is owned by user and group root:root with the permissions 775. The parent directory, /usr/lib/nagios, is also owned by user and group root:root with the permissions 755. Do I need to change the ownership on the two parent directories to user and group nagios:nagios with permissions 775, or is there something else that I should do? -Original Message- From: Andy Shellam (Mailing Lists) [mailto:[EMAIL PROTECTED] Sent: Monday, December 18, 2006 11:36 AM To: Kaplan, Andrew H. Cc: Nagios Users mailinglist Subject: Re: [Nagios-users] Return Code 127 This usually means Nagios cannot execute the plugin (on the server). If it was NRPE client-side it would give a different error. You need to be able to execute your plugin as the Nagios user, so check that first and any preceding directories above where that plugin is. Andy.

It's a bit more likely that your check command has an error in it. The messages you're seeing nearly always mean you're trying to run a plugin that isn't there. What does your check command look like? If it uses variables, make sure they're set to what you think they are. - Take Surveys. Earn Cash.
