How to Install and Configure Samba Server on Linux for File Sharing

Samba makes it easy to share files and folders between Linux and Windows systems over a network. Whether you need a simple shared folder for home use or secure file sharing for multiple users, Samba provides a flexible solution.

In this tutorial, you’ll learn how to install Samba on Linux, create shared directories, configure user access, and manage permissions. The guide includes both guest-access and authenticated user setups, making it suitable for beginners and advanced users alike.

Prerequisites

Before you begin, make sure you have:

• A Linux system with administrative (sudo) access
• An active network connection
• Basic familiarity with the terminal
• A firewall configured to allow Samba traffic if needed

Step 1: Install Samba on Linux

Most Linux distributions include Samba in their official package repositories, making installation quick and straightforward.

Install Samba on Ubuntu and Debian

First, update your package list:

sudo apt update

Then install Samba:

sudo apt install samba

Verify the Installation

Check the installed Samba version:

smbd --version

If the command returns a version number, Samba has been installed successfully.

Note: Updating your system before installing new packages can help avoid dependency-related issues.

Install Samba on RHEL, CentOS, or Fedora

Run the following command:

sudo dnf install samba samba-client samba-common

After installation, verify it with:

smbd --version

Step 2: Configure a Basic Samba Share

Samba settings are stored in the configuration file:

/etc/samba/smb.conf

The following example creates a shared folder that can be accessed over the network.

Create the Shared Directory

Create a directory for sharing:

sudo mkdir -p /srv/samba/shared_folder

Set directory permissions:

sudo chmod 2775 /srv/samba/shared_folder

Configure ownership for guest access:

sudo chown nobody:nogroup /srv/samba/shared_folder

Edit the Samba Configuration File

Open the Samba configuration file:

sudo nano /etc/samba/smb.conf

Scroll to the end of the file and add:

[SharedFolder]
path = /srv/samba/shared_folder
browsable = yes
read only = no
guest ok = yes

Configuration Explained

• path specifies the shared folder location.
• browsable = yes allows users to see the share.
• read only = no enables file modifications.
• guest ok = yes allows access without authentication.

Important: Guest access is convenient but less secure. For production environments, use authenticated users instead.

Restart Samba Services

Apply the configuration changes:

sudo systemctl restart smbd

Enable Samba to start automatically after reboot:

sudo systemctl enable smbd

Allow Samba Through the Firewall

If UFW is enabled, allow Samba traffic:

sudo ufw allow 'Samba'

This ensures other devices on the network can access the shared folder.

Step 3: Access the Share from Windows

Open File Explorer on the Windows system.

In the address bar, enter:

\\<IP-address-of-Linux-machine>\SharedFolder

Example:

\\10.228.12.83\SharedFolder

If the Samba configuration is correct, the shared folder should open immediately.

Step 4: Add and Manage Samba Users

For secure file sharing, Samba can require users to authenticate before accessing shared resources.

Create a Linux User

Every Samba user must first exist as a Linux user account.

Create a new user:

sudo adduser sambauser

Follow the prompts to set a password and complete the account creation process.

Add the User to Samba

Create a Samba password for the user:

sudo smbpasswd -a sambauser

Enable the account:

sudo smbpasswd -e sambauser

Note: The Samba password can be different from the Linux account password.

Step 5: Create a Secure Samba Share

To restrict access to specific users, update the share configuration.

Open the configuration file:

sudo nano /etc/samba/smb.conf

Replace or add the following section:

[SecureShare]
path = /srv/samba/shared_folder
valid users = sambauser
guest ok = no
writable = yes
browsable = yes

What This Configuration Does

• Restricts access to sambauser
• Disables guest access
• Allows reading and writing files
• Makes the share visible on the network

Save the file and restart Samba:

sudo systemctl restart smbd

Test the Secure Share from Windows

Open File Explorer and browse to:

\\10.228.12.83\SecureShare

When prompted, enter the Samba username and password created earlier.

Managing Samba Users

The following commands are useful for user administration:

Add a Samba User

sudo smbpasswd -a username

Enable a User

sudo smbpasswd -e username

Disable a User

sudo smbpasswd -d username

Delete a Samba User

sudo smbpasswd -x username

Advanced Samba Sharing Options

Once basic file sharing is working, you can customize access permissions to better match your requirements.

Create a Read-Only Share

A read-only share allows users to view files without modifying or deleting them.

Share Configuration

[ReadOnlyShare]
path = /srv/samba/readonly
valid users = sambauser
read only = yes
guest ok = no
browsable = yes

Create and Configure the Folder

sudo mkdir -p /srv/samba/readonly
sudo chown -R root:sambauser /srv/samba/readonly
sudo chmod -R 755 /srv/samba/readonly

Note: Ensure the directory exists and has the correct permissions before accessing it through Samba.

Configure Group-Based Access

Group-based permissions simplify management when multiple users need access to the same share.

Create a Group

sudo groupadd sambashare

Add Users to the Group

sudo usermod -aG sambashare sambauser

Create the Shared Folder

sudo mkdir -p /srv/samba/groupfolder

Set ownership and permissions:

sudo chown -R :sambashare /srv/samba/groupfolder
sudo chmod -R 770 /srv/samba/groupfolder

Configure the Share

[GroupShare]
path = /srv/samba/groupfolder
valid users = @sambashare
writable = yes
guest ok = no
browsable = yes

Apply the changes:

sudo systemctl restart smbd

Assign Different Permissions to Different Users

You can grant write access to some users while giving others read-only access.

[MixedAccess]
path = /srv/samba/mixed
valid users = user1 user2
read list = user2
write list = user1
guest ok = no
browsable = yes

In this example:

• user1 can read and write files
• user2 has read-only access

Hide or Block Specific Files

Samba can hide files from users or completely prevent access.

Hide Files

hide files = /secret.txt/*.bak/

Block Access to Files

veto files = /secret.txt/*.bak/
delete veto files = yes

• hide files prevents files from appearing in directory listings.
• veto files blocks access to matching files entirely.
• delete veto files = yes allows deletion of vetoed files when applicable.

Conclusion

Samba provides a reliable way to share files between Linux and Windows systems. By installing Samba, creating shared directories, and configuring user permissions, you can build anything from a simple guest-access file share to a secure multi-user file server.
