sudo dnf install samba
The above command installs Samba along with its dependencies. The `dnf` package manager will handle the download and installation process. After the installation completes, it is important to start and enable the Samba service, so it starts automatically on boot:
sudo systemctl start smb
sudo systemctl enable smb
The first command starts the Samba service immediately, while the second command ensures that the Samba service will start automatically every time the system boots. To verify that the Samba service is running correctly, you can use the following command:
sudo systemctl status smb
This command provides a status report of the Samba service, showing whether it is active and running without issues. If any errors are reported, refer to the system logs for more detailed information.
After ensuring that the Samba service is running correctly, it is essential to adjust the firewall settings to allow Samba traffic. Use the following commands to add Samba services to the firewall rules:
sudo firewall-cmd --permanent --add-service=samba
sudo firewall-cmd --reload
The first command adds the Samba service to the firewall’s permanent rules, while the second command reloads the firewall to apply the changes. With these steps completed, you have successfully installed and configured the Samba Server on AlmaLinux 9 and Rocky Linux 9. This setup allows file sharing across different operating systems within the same network.
Configuring Samba Server
After successfully installing the Samba Server on AlmaLinux 9 and Rocky Linux 9, the next crucial step is configuring it to meet your specific needs. The primary configuration file for Samba is smb.conf, typically located in the /etc/samba/ directory. This file controls various aspects of Samba’s behavior, including shared directories and access permissions.
To begin, open the smb.conf file using a text editor of your choice, such as nano or vi:
sudo nano /etc/samba/smb.conf
In the smb.conf file, you will notice several sections, but the most critical ones for basic configuration are [global] and [share]. The [global] section contains settings that apply globally to the Samba server, while the [share] section defines specific shared resources.
In the [global] section, you may configure the following common settings:
workgroup = WORKGROUP server string = Samba Server %v netbios name = samba
The workgroup parameter sets the Windows workgroup name. The server string parameter provides a description of the server, and netbios name allows you to specify the NetBIOS name for the server.
Next, define a shared directory in the [share] section. For example, to share a directory named shared located in /srv/samba/, you can add the following configuration:
[shared] path = /srv/samba/shared browsable = yes writable = yes guest ok = no valid users = @smbgroup
Here, path specifies the directory to be shared, browsable allows the share to be visible in network browsers, and writable enables write access. Setting guest ok to no restricts guest access, and valid users specifies allowed users or groups.
Ensure to create the shared directory and set appropriate permissions:
sudo mkdir -p /srv/samba/shared sudo chown -R :smbgroup /srv/samba/shared sudo chmod -R 2770 /srv/samba/shared
After making these changes, restart the Samba service to apply the new configuration:
sudo systemctl restart smb nmb
With these configurations, your Samba server should be effectively set up to share directories with defined access permissions, tailored to your specific requirements.
Creating Samba Users
Creating and managing Samba users is a crucial step in setting up a Samba server on AlmaLinux 9 and Rocky Linux 9. Proper user management ensures that shared resources are accessible only to authorized individuals, maintaining both security and efficiency.
To add a new Samba user, you first need to ensure that the user exists on the system. You can create a new system user using the following command:
sudo useradd -m <username>
Next, set a password for the new user:
sudo passwd <username>
Once the system user is created, the next step is to add the user to the Samba database. This is done using the smbpasswd command:
sudo smbpasswd -a <username>
You will be prompted to enter and confirm a password for the Samba user. This password can be different from the system user password, providing an additional layer of security.
To manage existing Samba users, you can use the smbpasswd command with different options. For example, to disable a Samba user, use:
sudo smbpasswd -d <username>
To re-enable the user, use:
sudo smbpasswd -e <username>
User permissions play a vital role in securing shared resources. You can assign appropriate permissions by configuring the smb.conf file, typically located in /etc/samba/. Here, you can specify which users or groups have access to specific shared directories. For instance:
[shared_folder] path = /srv/samba/shared_folder valid users = <username>
Best practices for user management include regularly updating passwords, monitoring user activity, and removing obsolete users from the system to prevent unauthorized access. Proper user management not only enhances security but also helps in maintaining an organized and efficient Samba server environment.
Testing Samba Configuration
After configuring your Samba Server, it is crucial to test the setup to ensure it is functioning correctly. Proper testing involves verifying that the server is running, examining log files for any errors, and testing access from both Linux and Windows clients.

sudo systemctl status smb
sudo systemctl status nmb
These commands will display the current status of the Samba services. Both services should be active and running. If they are not, you may need to start them using:
sudo systemctl start smb
sudo systemctl start nmb
Next, examine the log files for any errors. The Samba logs can provide valuable insight into any issues that may arise. You can find the logs in the following directory:
/var/log/samba/
Check the log.smbd and log.nmbd files for any error messages or warnings. Address any issues noted in the logs by adjusting your configuration files accordingly.
Once you have verified that the Samba services are running and there are no errors in the logs, proceed to test access from a Linux client. Use the following command to list the shared directories:
smbclient -L <your-server-ip> -U <your-username>
Replace <your-server-ip> with the IP address of your server and <your-username> with your Samba username. You should see a list of shared directories if the configuration is correct.
To test access from a Windows client, open the Run dialog by pressing Win + R and enter:
\<your-server-ip>
Again, replace <your-server-ip> with your server’s IP address. You should be able to see the shared directories and access them if the configuration is correct.
