Issue 1 Contact your service provider or the company that gave you your IP numbers, ask them to set up reverse name service. Server is a Google Cloud Compute instance. The tutorial on google cloud https://cloud.google.com/compute/docs/instances/create-ptr-record talks about verifying the domain name... as part of that process it asks for one to place a verification file on the server webspace. How am i supposed to do that exactly? (This server doesnt have its own website, its used as a hosting platform for other client websites). Am i supposed to setup a website for the server so google can verify i own the domain? Issue 2 Also, just want to have someone check the following is correct...i read somewhere about ip address. Should it be included in the hosts file? when i enter hostname -f it returns server3.mydomain.com /etc/hosts file is as follows... 127.0.0.1 localhost ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6-allrouters xx.xxx.x.x server3.mydomain.com.au server3 #xx.xxx.x.x server3.c.googlename-1.internal server3 # Added by Google xxx.xxx.xxx.xxx metadata.google.internal # Added by Google Issue 3 Finally, my server doesnt have any file called /etc/hostname. Should i create one?
