This script is no use!

a) Package “sudo” is required
b) Dangerous settings in /etc/sudoers are required
b) User “nagios” needs shell like /bin/bash
c) Selinux complaints, gosh why could that be xD
d) Script it self needs fiddling until it works

Don’t use this script if you don’t want to compromise your system security!

Try using the official check_ide_smart plugin!

Sorry, only my opinion.

Anyway thanks to the creator of this script for investing time.
