How To Configure Samba Share on Debian 11 / Debian 10

Normally when you launch the system’s file manager on Linux/Windows system, you will see network shares advised on your network. These shares are only allowed if remote users are connected to the machine.

Samba is a free software that enables one to share files across the network using the SMB(Server Message Block) protocol. This tool was developed by Andrew Tridgell in December 1991 and January 1992.Vorlage:Anchor Vorlage:Anchor

The cool features associated with Samba are:* It is easy and quick to deploy

• It offers secured data transfer
• Multichanel technology
• Message signing-with digital signing – users who receive the data packets are assured of the origin point authenticity.
• Allows concurrent operations.(simultaneous access to the files)
• It offers good performance under heavy loads.
• Samba supports POSIX extensions for CIFS/SMB
• Supports NetBIOS over TCP/IP (NBT)
• It supports the NT-style printing service (SPOOLSS)

Samba is supported on various platforms such as Windows and Unix operating systems i.e Solaris, Linux, AIX, and BSD variants.Vorlage:Anchor Vorlage:Anchor

This guide will equip you with the required knowledge on how to configure Samba Share on Debian 11 / Debian 10.

Step 1 – Install Samba on Debian 11 / Debian 10

We will start off by installing Samba on Debian 11 / Debian 10. This is easy since it is available in the default Debian repositories.Vorlage:Anchor Vorlage:Anchor

sudo apt install samba smbclient cifs-utils

Dependency tree:

The following additional packages will be installed:

 attr ibverbs-providers keyutils libcephfs2 libgfapi0 libgfrpc0 libgfxdr0

The following NEW packages will be installed:

 attr cifs-utils ibverbs-providers keyutils libcephfs2 libgfapi0 libgfrpc0
 libgfxdr0 libglusterfs0 libibverbs1 librados2 librdmacm1
 python3-cffi-backend python3-cryptography python3-dnspython python3-gpg

0 upgraded, 29 newly installed, 0 to remove and 0 not upgraded. Need to get 24.4 MB of archives. After this operation, 84.7 MB of additional disk space will be used. Do you want to continue? [Y/n] y

Step 2 – Set the Samba Global settings

The Samba configuration file is located under /etc/samba/smb.conf. In this file, there are several changes we need to make. Although Debian is intelligent enough to provide default configurations, it is also good to verify this.

Open the file using a preferred editor.

sudo vim /etc/samba/smb.conf

In the file, make make adjustments as you deem fit, example for workgroup.

workgroup = WORKGROUP

Step 3 – Create Shared Samba Directory

Here, you can share both public and private directories. So we will create the two directories as below.

sudo mkdir /public sudo mkdir /private

Now edit the Samba conf and add the two directories.

sudo vim /etc/samba/smb.conf

At the end of the file, add the shares and authentication methods to access it.Vorlage:Anchor Vorlage:Anchor

[public]

  comment = Public Folder
  path = /public
  writable = yes
  guest ok = yes
  guest only = yes
  force create mode = 775
  force directory mode = 775

[private]

  comment = Private Folder
  path = /private
  writable = yes
  guest ok = no
  valid users = @smbshare
  force create mode = 770
  force directory mode = 770
  inherit permissions = yes

Step 4 – Create Samba Share User and User Group

We need the Samba share user group to access the Private share as specified in the conf above. So we will create the group as below.

sudo groupadd smbshare

Add the necessary permissions for the private share.

sudo chgrp -R smbshare /private/ sudo chgrp -R smbshare /public

Set the right directory permissions.

sudo chmod 2770 /private/ sudo chmod 2775 /public

In the above command, the value 2 at the beginning, stands for the SGID bit. This allows newly created files to inherit the parent group.

Next, create a no login local user to access the private share.

sudo useradd -M -s /sbin/nologin sambauser

Add the user to the Samba share group created above.

sudo usermod -aG smbshare sambauser

Now create an SMB password for the user.

sudo smbpasswd -a sambauser

Enable the created account:

sudo smbpasswd -e sambauser

Step 5 – Verify the Samba configuration

Once changes have been made to the config file, it is recommended that you test it using the below command:

sudo testparm

Execution output:

Load smb config files from /etc/samba/smb.conf Loaded services file OK. Weak crypto is allowed Server role: ROLE_STANDALONE

# Global parameters [global]

       interfaces = 192.168.205.0/24 eth0
       log file = /var/log/samba/log.%m
       logging = file
       map to guest = Bad User
       max log size = 1000
       obey pam restrictions = Yes
       pam password change = Yes
       panic action = /usr/share/samba/panic-action %d
       passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
       passwd program = /usr/bin/passwd %u
       server role = standalone server
       unix password sync = Yes
       usershare allow guests = Yes
       idmap config * : backend = tdb

..... [public]

       comment = Public Folder
       force create mode = 0775
       force directory mode = 0775
       guest ok = Yes
       guest only = Yes
       path = /public
       read only = No

[private]

       comment = Private Folder
       force create mode = 0770
       force directory mode = 0770
       inherit permissions = Yes
       path = /private
       read only = No
       valid users = @smbshare

The above output shows that everything is configured appropriately. Now proceed as below.

Vorlage:Anchor Vorlage:Anchor Create demo files in the Samba shares:

sudo mkdir /private/demo-private /public/demo-public sudo touch /private/demo1.txt /public/demo2.txt

Restart the Samba service for the changes to apply.

sudo systemctl restart nmbd

If you have a firewall running, you need to allow remote access from the specified IP range:

sudo ufw allow from 192.168.205.0/24 to any app Samba

Step 6 – Access the Shares from the Client.

This guide demonstrates how to access the Share files using both Windows and Linux systems.

First, try accessing the share from your local machine.

Vorlage:Anchor Vorlage:Anchor $ smbclient '\\localhost\private' -U sambauser Enter WORKGROUP\sambauser's password: Try "help" to get a list of possible commands. smb: \> ls

 .                                   D        0  Tue Feb  8 01:31:42 2022
 ..                                  D        0  Tue Feb  8 01:25:51 2022
 demo1.txt                           N        0  Tue Feb  8 01:31:42 2022
 demo-private                        D        0  Tue Feb  8 01:31:32 2022

               39987708 blocks of size 1024. 32647972 blocks available

smb: \> exit

Now proceed as set up clients.

1. Setup a Windows Client

To access the share from Windows, browse using the IP address of the Samba share system as below.

Vorlage:Anchor Vorlage:Anchor Open a run box using Win+R and proceed as shown.

"How To Configure Samba Share on Debian 11 Debian 10 1"

The shared folders should appear as below.

"How To Configure Samba Share on Debian 11 Debian 10 1 1"

Open one of the folders and create a file.

Vorlage:Anchor Vorlage:Anchor "How To Configure Samba Share on Debian 11 Debian 10 6"

The file should be visible on the Samba server machine.

"How To Configure Samba Share on Debian 11 Debian 10 7 1"

Now mount the Samba share permanently on your Windows system. Click on This PC->Map Network Drive

"How To Configure Samba Share on Debian 11 Debian 10 2"

Provide the Path details as below.

Vorlage:Anchor Vorlage:Anchor "How To Configure Samba Share on Debian 11 Debian 10 3"

Enter the Samba user credentials.

"How To Configure Samba Share on Debian 11 Debian 10 4"

You will have the share available as shown.

"How To Configure Samba Share on Debian 11 Debian 10 5"

2. Setup a Linux client

To set up a Linux client, you will need Samba packages:

sudo apt install samba-client cifs-utils

Once installed, navigate to File manager->Other locations and add your share using the syntax below.

smb://servername/Share_name

For example:

"How To Configure Samba Share on Debian 11 Debian 10 8"

Enter the credentials for the samba user.

"How To Configure Samba Share on Debian 11 Debian 10 9"

That is it! You have your Samba share as below.

Vorlage:Anchor Vorlage:Anchor "How To Configure Samba Share on Debian 11 Debian 10 10"

Voila!

I hope you enjoyed this guide on how to configure Samba Share on Debian 11 / Debian 10. Now you can easily share files over a network between Windows and Linux systems.
