A little rough around the edges

I had the same problem as Cipher, where the script would bail at line 13. Turns out the problem is that this script has hardcoded a path for the check_nt script (CHNT variable) it depends on (I believe it was the default location for debian-based systems), and in my case (running on CentOS), that script didn’t exist in that location. After modifying the path, there was another error that came up, this time the error was in the OKVMS & CRITVMS variables–my particular NSClient machines require a password, and this wasn’t supplying one. So adding a -s to the end of those variables fixed it, and the script now works.
