I have another sudo /etc/nagios/plugin and that works. Also, su-ing to nagios and then running the command by hand works. so I'm still stuck.... <pre class="moz-signature" cols="72">Hari Sekhon </pre> Andy Shellam (Mailing Lists) wrote: <blockquote cite="mid45DC5FA5.1000201@mailnetwork.co.uk" type="cite"> <meta content="text/html;charset=ISO-8859-1" http-equiv="Content-Type"> I had this problem, and had to put the full path to sudo (/usr/bin/sudo) in nrpe's config.

I have the plugin in the configuration of nrpe and execute /usr/nagios/libexec/check_nrpe -H hostname -c check_plugin NRPE: Unable to read output The definition of the command call in nrpe.cfg is as follows: command[check_plugin]=sudo /etc/nagios/check_plugin and I have the following line in /etc/sudoers: nagios ALL=(ALL) NOPASSWD: /etc/nagios/check_plugin NRPE is running as the nagios user. When logged in as root I can do su - nagios sudo /etc/nagios/check_plugin OK: test passed so I don't understand why it is saying no output. I tried changing the nrpe.cfg to have > /tmp/output.log 2>&1 at the end of it but the file /tmp/output.log was not created so I assume that there really was no output when run from the check_nrpe command. This works on all my other servers (most of which are Gentoo) and this one is RHEL4. SELinux is disabled. I can execute all other nrpe checks correctly on this server including another one which also uses sudo. The difference in Distro is the only thing I can think of but it even works from the command line. I am using nrpe 2.6. I have racked my brains but can't think of anything else. Any ideas on this? -h </pre> </blockquote> <pre wrap=""> ------------------------------------------------------------------------- Take Surveys. Earn Cash.
