Getting Started
Once your DNS server has been deployed, the following links explain how to connect to a Linux VM:
- How to connect to a Linux VM on Azure
- How to connect to a Linux VM on AWS
- How to connect to a Linux VM on GCP
Once connected and logged in, the following section explains how to start using BIND9 DNS / Webmin.
Access Webmin
The server has Webmin installed, allowing you to manage the server via a web portal.
First you need to update the miniserv.conf file
From your SSH terminal run the following command:
sudo nano /etc/webmin/miniserv.conf
Then scroll down to ‘SSL=1‘ and change it to ‘SSL=0‘
This is so you dont receive SSL errors when accessing the Webmin portal.
Press Ctrl+O to save and then Ctrl+X to exit the config file
Run the following command to restart the Webmin services
sudo /etc/init.d/webmin restart
Now access the following URLs to access the Webmin portal using the servers IP:
http://PublicIP:10000
Or
http://PrivateIP:10000
Login using the root user and password.
Using BIND9 DNS Server
You can manage the DNS server via Webmin or via your SSH terminal.
Manage DNS via Webmin
If you login via Webmin you can manage DNS as per the following screenshot:
Browse to the Servers tab – BIND DNS server.
Click on ‘Create Master Zone’ if you want to create your first DNS Zone
Under Domain name / Network add the name of this DNS zone you want to create. Add email address in the email address filed and then hit ‘Create’
When you return to the zone list you will see the different options on creating DNS entries. Under ‘Address’ is where you would normally add entries.
When you have finished, press the apply changes button on the top right.
