Changing your DNS provider

Amahi defaults to providing DNS forwarding through OpenDNS.

If you would like to change that to your router or your ISP or some other provider, follow the guidance below:

Amahi 7 or greater (Fedora)

Log in to your dashboard as your 1st admin user, the accomplish the following:

• Verify Advanced Settings is enabled.
• Select Network tab, then Settings.
• Choose desired DNS provider:
  • Preconfigured (Google Public DNS, OpenNIC DNS, or OpenDNS)
  • Custom
    • Enter the IP addresses for the DNS provider.
    • Select Update DNS IPs

NOTE: You may need to renew the DHCP lease on your clients to use the new DNS provider.

Amahi 6 (Ubuntu 12.04.x)

This has to be done via command line. Issue this command, provided you have two IP addresses of the providers:

hda-change-dns FIRST_DNS_IP SECOND_DNS_IP

For instance, if you would like to use Google's Public DNS service, you would do:

hda-change-dns 8.8.8.8 8.8.4.4

To revert back to the default OpenDNS settings use:

hda-change-dns 208.67.222.222 208.67.220.220

In some cases you may need to use the full path for hda-change-dns

example: /usr/bin/hda-change-dns 208.67.222.222 208.67.220.220
