Hostname is the name of the computer, when we install Ubuntu where we have to enter the computer name. Sometimes we make the hostname appear in the terminal after the @ sign (@ hostname). When we want to change hostnames, there are several ways we should go between:
* Using GUI
* Command Line
By using these 2 ways. The way we can use in some os one of them in Linux Mint, Debian, and distros that are still a family, because for the same configuration.
Hostname is the name given to a computer on a network. hostname is just a name of the computer, the only use to identify a computer in the network. Hostname is also displayed in the terminal.
As you can see above, his username is a geek, while his hostname is Carddisk.
This hostname should uniquely identify a computer on the network. There are some rules defined for the hostname. Hostnames can only contain letters, numbers, and hyphens characters, and character periods. A hostname must start and end with a letter or number. hostname must be between 2 and 63 characters.
You can change your hostname as you wish, but you should not use the same hostname on two different computers on a network, as this may cause problems.
To change the hostname using GUI, the first step you should do is to open System Settings. Then select Details.
now we will see the column to change the device name. Change Device Name.
When we want to check the hostname in the terminal then it has changed.
If we want to change hostaname using terminal, here's how:
sudo nano / etc / hostname
Open the terminal. To change your hostname you will need to edit your / etc / hostname file, which Ubuntu, Mint and other Debian based distributions store the host name here.
We can change the name according to our wishes. To view the changes you need to restart the computer.
