Just wanted to see if anyone had any comments about this. In order to get check_disk_smb to work on hidden shares such as C$ and D$, you have to provide a windows Administrator password in the nagios config files. That means anyone who gets access to the nagios config files will be able to see the windows Administrator password in cleartext. Security here is problematic. It looks like the nagios config files have to be well protected. Any suggestions about dealing with this?
