Learn how to – 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.
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.
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.
sudo apt install samba smbclient cifs-utilsDependency tree:
The following additional packages will be installed:

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.confIn the file, make make adjustments as you deem fit, example for workgroup.
workgroup = WORKGROUPStep 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 /privateNow edit the Samba conf and add the two directories.
sudo vim /etc/samba/smb.confAt the end of the file, add the shares and authentication methods to access it.
[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 = yesStep 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 smbshareAdd the necessary permissions for the private share.
sudo chgrp -R smbshare /private/
sudo chgrp -R smbshare /publicSet the right directory permissions.
sudo chmod 2770 /private/
sudo chmod 2775 /publicIn 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 sambauserAdd the user to the Samba share group created above.
sudo usermod -aG smbshare sambauserNow create an SMB password for the user.
sudo smbpasswd -a sambauserEnable the created account:
sudo smbpasswd -e sambauserStep 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 testparmExecution output:
Load smb config files from /etc/samba/smb.conf
Loaded services file OK.

# 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 = *Entersnews*spassword:* %nn *Retypesnews*spassword:* %nn *passwordsupdatedssuccessfully* .
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 = @smbshareThe above output shows that everything is configured appropriately. Now proceed as below.
Create demo files in the Samba shares:
sudo mkdir /private/demo-private /public/demo-public
sudo touch /private/demo1.txt /public/demo2.txtRestart the Samba service for the changes to apply.
sudo systemctl restart nmbdIf 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 SambaStep 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.
$ smbclient '\localhostprivate' -U sambauser
Enter WORKGROUPsambauser'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: > exitNow 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.
Open a run box using Win+R and proceed as shown.
The shared folders should appear as below.
Open one of the folders and create a file.
The file should be visible on the Samba server machine.
Now mount the Samba share permanently on your Windows system. Click on This PC->Map Network Drive
Provide the Path details as below.
Enter the Samba user credentials.
You will have the share available as shown.
2. Setup a Linux client
To set up a Linux client, you will need Samba packages:
sudo apt install samba-client cifs-utilsOnce installed, navigate to File manager->Other locations and add your share using the syntax below.
smb://servername/Share_nameFor example:
Enter the credentials for the samba user.
That is it! You have your Samba share as below.
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.
