Hello I have a VPS with Ubuntu 16.04 / PHP 7 on Sydney (Vultr), 2 GB ram. I install Webmin, manually some weeks ago (apt-get install was not possible at this time for Webmin on Ubuntu 16.04).
Some problem with hostname and DNS. When I check the configuration in Virtualmin :
Your system has 1.95 GB of memory, which is at or above the Virtualmin recommended minimum of 256 MB.
BIND DNS server is installed, and the system is configured to use it. However, the default master DNS server vtr01 is not a fully qualified domain name.
I know that the hostname was not FQDN. I change it in Webmin / Networking / Network configuration / Hostname and DNS client :
I replace hostname "vtr01" by "vtr01.mydomain.ovh" . So, now the hostname is a FQDN :
But when I try to check the Virtualmin configuration, always the same error :
"However, the default master DNS server vtr01 is not a fully qualified domain name."
Why ? Thanks for your help ;-) Didier
