What is Hostname?
In this article, I will share how to change the computer name or hostname on linux. By default an OS will create a computer name or hostname, which is useful for distinguishing devices on the local network.
Basically the hostname is an IP address, but to make it easier for the user, it is converted to text. This is what can appear when you open the network and see the computers connected into it.
For information, I’m currently using the Pop OS Linux distribution, which is a derivative of Ubuntu Linux. Its use is very easy, stable and lightweight. It is suitable for those of you who are in programmer work.
You can also use the steps below on other Linux Operating System.
To check the computer name, you just need to use the terminal as shown below:
Or use a command in the terminal:
it will show the results like this:
neon@pop-os:~$ hostname pop-os
The result is “pop-os“.
Comand to change Hostname Linux
To change this name, simply edit the file called “hostname” which is in the “/etc” folder.
To do it, we have to open using a text editor in root state.
For example, I open the file using the text editor “gedit” so the command is:
sudo gedit /etc/hostname
The result will open a file like this:
Now change the text “pop-os” to something else. For example I want to change to the text “linux“, then I save the file.
now logout or reboot your linux distro.
Now, reload the terminal and you will see in the image that the hostname has become “linux”. Pay attention to the following picture:
