(Return code of 13 is out of bounds : (No output on stdout)

[mhedtcke]

I've searched all over these forums and the internet and I cannot seem to figure out a solution to this. I am getting this error on every thing I have set up in Nagios.

(Return code of 13 is out of bounds : (No output on stdout) stderr: execvp(/usr/local/nagios/libexec/check_em01, ...) failed. errno is 13: Permission denied))

or

Info: (Return code of 13 is out of bounds : (No output on stdout) stderr: execvp(/usr/local/nagios/libexec/check_ping, ...) failed. errno is 13: Permission denied))

I've reset the plugins. I've checked the permissions. I made sure there were no temp files restricted to the root account.

Any thoughts or assistance is appreciated.

it looks like a permissions thing to me, please show the output of the following

Code: Select all

ls -al /usr/local/nagios/libexec/check_ping
ls -al /usr/local/nagios

Here is a screenshot of the command and output.

ya, check_ping isn't executable

run

Code: Select all

chmod +x /usr/local/nagios/libexec/*
chmod u+s /usr/local/nagios/libexec/check_dhcp
chmod u+s /usr/local/nagios/libexec/check_icmp

AWESOME! That worked. I am pretty new to nagios and a linux novice. Can you explain to me what that did?

Sure thing. this command took all the file in /usr/local/nagios/libexec/ and made them executable by all

Code: Select all

chmod +x /usr/local/nagios/libexec/*

There are 2 special plugins though that need different permissions do this command allows the plugins the be setuid root (I'll spare you what that means, but basically the plugins can run as root)

Code: Select all

chmod u+s /usr/local/nagios/libexec/check_dhcp
chmod u+s /usr/local/nagios/libexec/check_icmp
