    Question How to change hostname from `localhost.localdomain` to something else?

    I using started working on React apps. When I try and start `npm start` it tries to run on `localhost.localdomain:3000`. `node` gets the name from `process.env.HOST`. I want to change the `hostname`. How do I do it? (I guess I can simply change the configuration files for the React apps but I have to do it for every app.)

    What I tried:

    ```
    > sudo hostname pc0

    > hostnamectl
    Static hostname: n/a
    Transient hostname: pc0
    ```

    Still node tries to start the server on `localhost.localdomain:3000` instead of desired 'pc0:3000'.

    YaST > System > Network settings. There is a tab there to set the hostname.
