Welcome to our guide on how to install and configure Samba Share on Ubuntu 22.04|20.04|18.04 Linux system. Samba is an open-source implementation of the Server Message Block (SMB) and Common Internet File System (CIFS) protocols that provides file and print services between clients across various operating systems.
By configuring Samba server share on Ubuntu 22.04|20.04|18.04, you can easily share folders or files between Windows and Linux operating systems. In this context, the Windows machine will be used as a client to access Samba share on Linux.
Step 1: Install Samba Server on Ubuntu 22.04|20.04|18.04 LTS
To install Samba on Ubuntu 22.04|20.04|18.04, use the commands:
sudo apt -y update
sudo apt -y install sambaIf you’re using static IP address, answer no when asked to use WINS settings from DHCP.
Once the package is installed, proceed to step 2 where we will do the configuration and manage Samba service.
Step 2: Configure Samba Share on Ubuntu 22.04|20.04|18.04
Samba uses configuration file in /etc/samba/smb.conf. If you change this configuration file, the changes do not take effect until you restart the Samba daemon.
Let’s start by creating a directory to share via Samba. The directory must exist before it can be configured in smb.conf. We will create one under /home.
sudo mkdir -p /home/shareAccess to All without Authentication (Not recommended)
The directory should be readable and writable for all users.
sudo chmod 777 /home/share Configure Samba share on /etc/samba/smb.conf file.
$ sudo vim /etc/samba/smb.conf
[global]
# Configure correct UTP
unix charset = UTF-8
# Change this to the workgroup/NT-domain name your Samba server will be part of
workgroup = WORKGROUP
bind interfaces only = yes
# Set share configuration at the end
[Docs]
path = /home/share
writable = yes
guest ok = yes
guest only = yes
create mode = 0777
directory mode = 0777
Configuration details:
- Docs – Samba share name
- path = /home/share – Directory to share
- guest ok = yes – Turn on guest share
- guest only = yes – All protected as guests
- writable = yes – Set share directory as writable
- create mode = 0777 & directory mode = 0777 – Allow access to all
Configure Secure Samba Share (Recommended)
Set group ownership of Samba share directory to sambashare group.
sudo chgrp sambashare /home/shareCreate samba share users. Replace user1 with samba share user to create.
sudo useradd -M -d /home/share/user1 -s /usr/sbin/nologin -G sambashare user1
sudo mkdir /home/share/user1
sudo chown user1:sambashare /home/share/user1
sudo chmod 2770 /home/share/user1
Set the user password and confirm.
$ sudo smbpasswd -a user1
New SMB password:
Retype new SMB password:
Added user user1.Enable samba account after setting the password using the command:
$ sudo smbpasswd -e user1
Enabled user user1.We created a user’s home directory inside Samba share parent directory and set ownership to the samba share group. Let’s create another user.
sudo useradd -M -d /home/share/smbadmin -s /usr/sbin/nologin -G sambashare smbadmin
sudo mkdir /home/share/smbadmin
sudo smbpasswd -a smbadmin
sudo smbpasswd -e smbadmin
sudo chown smbadmin:sambashare /home/share/smbadmin
sudo chmod 2770 /home/share/smbadmin
Configure Secure Samba share.
[user1]
path = /home/share/user1
read only = no
browseable = no
force create mode = 0660
force directory mode = 2770
valid users = @user1 @sambashare
[smbadmin]
path = /home/share/smbadmin
read only = no
browseable = yes
force create mode = 0660
force directory mode = 2770
valid users = @sambashare @smbadmin
Restart samba daemon after making the changes.
sudo systemctl restart smbd nmbdConfirm that the service is running.
If you have an active firewall, run:
sudo ufw allow 'Samba'Step 3: Configure Samba Clients
To access a Samba share on the Linux system, you need to install and configure Samba client.
### Install Samba client on Ubuntu / Debian ###
sudo apt update
sudo apt -y install smbclient cifs-utils
### Install Samba client on CentOS / RHEL / Fedora ###
sudo yum -y install samba-client cifs-utils
sudo dnf -y install samba-client cifs-utilsAccessing Samba share – Temporarily
$ smbclient //sambaserver/share -U sambausername
Example:
$ smbclient //192.168.122.52/user1 -U user1
WARNING: The "syslog" option is deprecated
Enter WORKGROUP\user1's password:
Try "help" to get a list of possible commands.
smb: \> list

Current directory is \192.168.122.52\user1\You can mount a samba share to a directory in your local Linux system using the mount and cifs type option.
$ mkdir -p ~/mounts/shares
$ mount -t cifs -o username=user1 //192.168.122.52/user1 ~/mounts/shares
$ df -h

You can use fstab file to persist Samba shares mounting through system reboots. In my example, I have the following line added to the end of /ect/fstab file.
//192.168.122.52/user1 /mnt/shares cifs credentials=/.sambacreds 0 0Then I created a credentials file.
$ cat /.sambacreds
username=user1
password=password
domain=WORKGROUPTest:
$ sudo mkdir -p /mnt/shares
$ sudo mount -a
$ df -hT | grep cifs
//192.168.122.52/user1 cifs 9.2G 1.6G 7.6G 18% /mnt/sharesFor Windows Desktop machines, follow the standard process of mounting a Samba share on Windows. That’s all on how to Install and Configure Samba on Ubuntu 22.04|20.04|18.04.
