DNS Service is not starting.

[Fattur]

I have ubuntu 14.04 vps. And when I write service bind9 start it says :
 * Starting domain name service... bind9

   ...fail!


and when i write named -g it says permission denied on sentora config file. I made  chmod 775 yet it was no solution after all. Output of named -g is:
