# Common services

## Samba

**Samba** is an open-source software suite that enables file and print sharing across different operating systems. It allows **Unix** and **Linux** systems to communicate seamlessly with **Windows** systems by implementing the **SMB/CIFS** protocol, which is the primary protocol used for file and print services in **Windows** networks.

Update the system package source:

```bash
sudo apt update && sudo apt upgrade -y
```

Install **Samba**:

```bash
sudo apt install samba -y
```

Check the status of **Samba** service:

```bash
sudo systemctl status smbd
```

If the service is not running (displayed as **inactive**), you can use the following command to start it:

```bash
sudo systemctl start smbd
```

And set it to start automatically on boot:

```bash
sudo systemctl enable smbd
```

Configure **Samba**:  
  
The configuration file for **Samba** is usually located at **/etc/samba/smb.conf**. You need to edit this file based on your network environment and sharing requirements.

Restart **Samba** service:  
  
After making changes to the configuration file, restart the **Samba** service to apply these changes:

```bash
sudo systemctl restart smbd
```

After completing the above steps, **Samba** service will be installed and running on the **Debian** system. You can now proceed to configure shared folders and user access permissions.
