In the interconnected world of computers, sharing files and printers across different operating systems is a common necessity. Samba, a free software re-implementation of the SMB/CIFS networking protocol, provides seamless file and print services to SMB/CIFS clients, making it an ideal solution for networking between Linux and Windows systems. This beginner’s guide will walk you through installing and configuring Samba on Ubuntu, setting up shared directories, and securing them for different user access levels.

Installing Samba on Ubuntu

Before diving into the configuration, the first step is to install Samba on your Ubuntu system. This process is straightforward and can be accomplished with a few commands in the terminal.

1. Update Your System: Ensure your system’s package database is up to date:

   sudo apt update

2. Install Samba: Install the Samba package using apt:

   sudo apt install samba

3. Verify Installation: Check if Samba is installed and running:

   sudo systemctl status smbd

You should see that the smbd service is active and running.

Configuring Samba

With Samba installed, the next step is to configure it to share files and directories on your network.

1. Backup Original Samba Configuration: It’s a good practice to back up the original configuration file before making changes:

   sudo cp /etc/samba/smb.conf /etc/samba/smb.conf.backup

2. Edit Samba Configuration: Open the Samba configuration file in your preferred text editor:

   sudo nano /etc/samba/smb.conf

Here, you can define your shared directories, printers, and administrative settings. For a basic shared directory, add the following to the end of the file:

   [ShareName]
   path = /path/to/shared/directory
   read only = no
   browsable = yes

Replace ShareName with a meaningful name for your shared directory and /path/to/shared/directory with the actual path to the directory you want to share.

3. Create the Shared Directory: If the directory you want to share doesn’t exist, create it:

   sudo mkdir -p /path/to/shared/directory

4. Set Directory Permissions: Adjust the permissions of the shared directory to ensure users can read, write, and execute within it:

   sudo chmod -R 0770 /path/to/shared/directory

5. Restart Samba Services: Apply the changes by restarting Samba’s services:

   sudo systemctl restart smbd nmbd

Managing Samba Users

Samba uses its own set of user accounts and passwords, separate from the Linux system accounts. To grant access to the shared directories, you must add users to Samba.

1. Add Linux User: First, ensure the user exists on your Linux system. If not, add them:

   sudo adduser username

Replace username with the desired username.

2. Add User to Samba: Then, add the user to Samba and set up a password:

   sudo smbpasswd -a username

Follow the prompts to set the Samba password.

Securing Shared Directories

To refine access to shared directories, you can adjust your Samba configuration to limit access based on user groups or individual users.

• Restrict Access to a Group: To allow only members of a specific group to access a shared directory, add the following to the directory’s configuration block in smb.conf:

  valid users = @groupname

• Restrict Access to Specific Users: Similarly, to restrict access to specific users, use:

  valid users = username1, username2

After making these changes, remember to restart the Samba services to apply them.
