303.1 File Share Configuration (weight: 4)

Introduction #

In this tutorial, we will dive into setting up and configuring CIFS (Common Internet File System) file shares using Samba on a Linux system. Samba is a free software re-implementation of the SMB networking protocol, and provides file and print services to SMB/CIFS clients. It allows the Linux system to interact with Windows clients and act as a server for files and printers.

Prerequisites #

A Linux system with administrative privileges.
Samba installed on your Linux system.
Basic knowledge of Linux command line and file permissions.

Key Knowledge Areas #

Installation and configuration of Samba.
Management of Samba users.
Creation and configuration of CIFS file shares.

Utilities #

smb.conf
smbpasswd
testparm
smbclient

Step-by-Step Guide #

Step 1: Installing Samba #

To install Samba on a Debian-based system, use the following command:

sudo apt-get update
sudo apt-get install samba

For Red Hat-based systems, you can use:

sudo yum update
sudo yum install samba

Step 2: Configuring Samba #

The main configuration file for Samba is /etc/samba/smb.conf. You need to edit this file to set up your file shares.

Backup the original configuration file:

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

Edit the configuration file:

Open the file with your favorite text editor, for example:

sudo nano /etc/samba/smb.conf

Add the following configuration to set up a simple share:

[global]
    workgroup = WORKGROUP
    server string = Samba Server %v
    netbios name = linuxbox
    security = user
    map to guest = bad user
    dns proxy = no

[shared]
    path = /srv/samba/shared
    writable = yes
    guest ok = yes
    guest only = yes
    read only = no
    force user = nobody

This configuration does the following:

Sets the workgroup and server name.
Configures the server to use user-level security.
Defines a share named [shared] that is accessible by guests.

Check the configuration for errors:
```
sudo testparm
```

Step 3: Adding Samba Users #

To access the Samba shares, users must be added to the Samba user database.

Create a new Linux user (if necessary):
```
sudo adduser samuser
```
Add the user to Samba:
```
sudo smbpasswd -a samuser
```
When prompted, enter and confirm the password for the Samba user.

Step 4: Managing Samba Service #

Start, stop, and restart the Samba service as needed:

sudo systemctl start smbd
sudo systemctl stop smbd
sudo systemctl restart smbd

Use smbclient to access the share from the command line:

smbclient //localhost/shared -U samuser

Enter the password when prompted, and you should have access to the shared directory.

Conclusion #

In this tutorial, you’ve learned how to set up and configure a Samba server to provide CIFS file shares. You’ve installed Samba, configured a file share, managed Samba users, and accessed the share using smbclient. This setup is fundamental for creating a file-sharing network in a mixed environment with Windows and Linux systems.
