Details
Gaia uses the Domain Name Service (DNS) to translate host names into IP addresses. To enable DNS lookups, you must specify the primary DNS server for your system. You can also specify secondary and tertiary DNS servers. When resolving host names, the system consults the primary name server. If a failure or time-out occurs, the system consults the secondary name server, and if necessary, the tertiary.
Rationale:
The purpose is to perform the resolution of system hostnames to Internet Protocol (IP) addresses.
Solution
Run the following command to set DNS server.
CLI:
Hostname> set dns primary
Hostname> set dns secondary
Hostname> set dns tertiary
GUI:
Navigate to Network Management > Hosts and DNS > DNS
Set Primary, secondary and tertiary DNS server address.
Default Value:
Not Configured
