Nagios Support Forum

Hi
I install http://assets.nagios.com/downloads/ncpa ... .amd64.deb in my Ubuntu 12.04.2 LTS bit.
and use the default config file except modifing token to 123 .


When I visit https://192.168.56.2:5693/api/?token=123
It redirects me to https://192.168.56.2:5693/error/Referen ... ot%20exist.
The web shows me ：
{
"error": "Referencing node that does not exist."
}


The listener log shows:
2014-03-21 12:55:57,282 2160 ERROR [Errno 13] Permission denied

Does anyone know what does it mean?
Thank you

When accessing:
Are you able to log in with the token you set? Or does it still error out?

Can you provide us with your ncpa.cfg in an attachment?

Yes , I can login the web using token 123 without any error.
But after login ,it shows error when I click "config " menu.

The web shows:
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

this is ncpa.cfg

It looks like this might be Ubuntu-specific:

The dev who wrote NCPA will be in tomorrow. I made a note to ask him about it then.
