To do it we have to add the –transient option on the hostnamectl command. It will only be active until we restart the system. However, we can define a temporary Hostname. When we establish a Hostname using the command hostnamectl or by editing the file /etc/hostname it becomes our static Hostname – it does not change. To do this, run the following command: hostnamectl Static, Transient and Pretty Hostnames Now, we have to verify that everything is working.

However, in the case where the computer has access to the Internet, it has to be combined with a domain. There are no restrictions on placing a Hostname on a private network. These identifiable names are called “Fully Qualified Domain Names” (FQDN) and include the name of the computer and the domain name associated with that computer. In this case, server1 is the hostname of the computer we want to access, and example is the domain. This indicates which “mini zone” of the Internet it is on. In public networks such as the Internet, the hostname has to be combined with the domain name. Therefore, the hostname is an identifier designed to make work easier for people, not for the computer.Īlthough it is a simple concept to learn, many people are often confused by it.
