How do I start a network service in Ubuntu?

To start a network service in Ubuntu, you can use the "systemctl" command with the "start" option and the name of the service. The "systemctl" command is a utility that allows you to control the system services and daemons on a Ubuntu system. It can be used to start, stop, restart, and enable or disable services.

To start a network service in Ubuntu, follow these steps:

1. Open a terminal window.

2. Check if the service you want to start is already running by using the "systemctl" command with the "is-active" option and the name of the service. For example:

systemctl is-active service-name

This will display the status of the service. If the service is already running, it will display "active". If the service is not running, it will display "inactive".

3. If the service is not running, start it by using the "systemctl" command with the "start" option and the name of the service. For example:

systemctl start service-name

This will start the service.

4. To check if the service is now running, use the "systemctl" command with the "is-active" option again. For example:

systemctl is-active service-name

This should display "active" if the service is now running.

With these steps, you should be able to start a network service in Ubuntu using the "systemctl" command. Consult the documentation of the "systemctl" command and the specific service for more information on how to control and manage services on a Ubuntu system.
