If you're trying to run the plugin locally as root then try as the nagios user instead (or whichever user nrpe runs as). I.e.: > su nagios -c 'usr/local/nagios/libexec/check_openvpn -H 127.0.0.1 -p 1195 -P mypwd -n' I doubt it would be caused by the missing newline, but if you think so you can certainly add one in the plugin since it's written in perl... Which version of Nrpe are you using?
