3AVE THE FILE AND CHECK THE SYNTAX OF YOUR FILES BY RUNNING
$ sudo named-checkconf
)F EVERYTHING IS CORRECT YOULL GET NO OUTPUT AND NO ERRORS #HECK THE CONFIGURATIONS FURTHER WITH named-checkzone:
$ sudo named-checkzone tiny.lab /etc/bind/zones/db.tiny.lab
$ sudo named-checkzone 128.10.in-addr.arpa /etc/bind/zones/db.10.128
9OULL SEE h/+v IF EVERYTHING CHECKS OUT )F NOT EDIT THE FILES ,EAVING OFF THE TRAILING h v IS A COMMON MISTAKE
Restart bind to get it up and running:
$ sudo service bind9 restart
7HEN bind9 RESTARTS DO A QUICK CHECK WITH THE dig utility, or simply open a browser and navigate to your mirror server at http://mirror.tiny.lab:
$ dig mirror.tiny.lab
FEATURE: The Tiny Internet Project, Part III
)F YOU SEE IN THE dig output, you’ve succeeded. DNS is working. You can complete your DNS setup by deploying a second 6- OR INSTALLING bind9 on a physically separate machine on your tiny internet network, but it’s not strictly necessary at this point. You also CAN SET THIS 6- TO START AUTOMATICALLY WHEN YOUR 0ROXMOX HOST STARTS so you have DNS running whenever your tiny internet is up.
