Changing the hostname
For Fedora Workstation, using the default GNOME desktop, open the Settings application and choose About.
GNOME Settings - About
You can replace the value in the Device name field with the name of your choosing. The effect of this field is as follows:
If you use a name that is shorter, contains only lowercase letters, numbers and/or dashes ("-"), this will set the host's static name, and the pretty name will be left blank.
If you enter a name that is more descriptive, contains mixed-case and other types of characters, this will set the pretty name, and a static name will be derived from that automatically.
You can see the effect of the change by using the `hostnamectl` command again:
Static hostname: emilys-2nd-dev-laptop
Pretty hostname: Emily's 2nd dev laptop
Icon name: computer-laptop
Chassis: laptop
Machine ID: 15fc9e69d007013025f31bc5272c4ed1
Boot ID: 41ac938872bae052294bcb277241ac93
Operating System: Fedora 33 (Workstation Edition)
CPE OS Name: cpe:/o:fedoraproject:fedora:33
Kernel: Linux 5.10.10-200.fc33.x86_64
Architecture: x86-64
In the previous example, "Emily's 2nd dev laptop" was entered via the Settings app, and the static hostname "emilys-2nd-dev-laptop" was set automatically.
Hostnames can also be set at the command line with the `hostnamectl set-hostname` command. For example:
sudo hostnamectl set-hostname --pretty "Emily's 2nd dev laptop"
sudo hostnamectl set-hostname --static emily-dev-2
