Nagios Support Forum

Hello,

I don't know if this is the right list for NDO, but i'll learn it on the hard way, though.
I installed NDO into a CentOS, and when i started Nagios i received the following message at nagios.log:

ndomod: Could not open data sink! I'll keep trying, but some output may get lost...

I figured out that nagios' user couldn't access NDO configuration file due to a permission issue. It took me some time to discover the source of the problem, so i thought that maybe an accurate error message can help on this.

I've applied the patch below against ndoutils-1.4b9.
