Debian: change hostname - so it'll work

You can change the host name under Debian during operation or permanently.

• To change the hostname during operation, enter the command "hostname" in the terminal and the new name after it. So the command is "hostname NEWER_NAME".
• If you want to change the host name permanently, you can edit it with any editor. The hostname is in the "/ etc / hostname" file.
• To be able to make the change immediately, simply use the script that is also executed when the system is started. To do this, enter "/etc/init.d/hostname.sh" in the terminal.
