Samba services how work with Ubuntu 20.04 LTS, this is what we will learn today. Let’s begin.

What you will learn:

1. Installing the package, with examples.
2. How to configure services.
3. Finally, how to mount and use samba shares.

Pre Requisites:

1. An Ubuntu 20.04 LTS Machine.
2. Also, MS Windows Desktop.
3. Samba packages, of course for Ubuntu.
4. Good internet connectivity.

Get Samba File share services ready:

Let’s get the Server ready first. Go and download Ubuntu OS. Second, install all required software as well.

Make required file changes

Update system

apt update

Install samba packages

#apt install samba

Let’s have a look is samba services are running proper or not?

# systemctl status smbd

Let’s see which files are visible in Samba default directory, will look something like below:

#cd /etc/samba/ && ls
gdbcommands smb.conf tls

Edit smb.conf file, it is recommended to take a backup of original file first.

Create a shred directory which you would be using to get accessed from MS Windows client, in our example we created folder named as “sambashare”.

# mkdir /home/ubnt/sambashare

Let’s edit /etc/samba/smb.conf file, Make required changed as per below, add changes at bottom of the .conf file:

# nano /etc/samba/smb.conf  
[Samba-Windows-Share]  
comment = for windows share
path = /home/ubnt/sambashare
read only = no
browsable = yes

Press ctrl+o followed by ctrl+x to save and exit from file.

Allow samba on firewall and start service.

#ufw allow samba
Rules updated
Rules updated (v6)

#service smbd restart

Setup Samba password and access shared folder

As, samba do not use default user’s password. Let’s defile samba password for existing user, in our case user is ubnt.

# sudo smbpasswd -a ubnt

Change file permissions for shared folder, so that end user can add or remove files, defile permissions as per your need.

# chmod 777 /home/ubnt/sambashare/

Now, Samba server is ready, lets switch to MS Windows and see. Open Run and provide Samba server IP Address. In our scenario that IP address was 192.168.1.239.

press enter, shared folder creds which we have created in previous step is visible:

Give user id and password created recently with smbpasswd command, in my scenario first attempt login didn’t work, but don’t worry, give another try. it will work.

Lets try to create folder or file and see, whether that file is visible in Linux Machine or not. I have created Test_Folder and Test_File.

Lets have a look in Ubuntu Samba server, if these files are visible or not.

Bingo! we have created and tested samba server successfully. Give a try!!

The post Configure Samba File share Services with Ubuntu 20.04 LTS appeared first on Linux Windows and android Tutorials.

Installation of Samba

login to your server from root user.

Use below command to install samba with necessary packages.

dnf install samba samba-common samba-client -y

Before configurations, make sure Windows machine is in same workgroup.
open the cmd prompt in Windows machine and run the following command

> net config workstation

Samba Configuration

before configuration rename samba default configuration file /etc/samba/smb.conf as backup.

# mv /etc/samba/smb.conf /etc/samba/smb.conf.default

Samba Anonymous File Sharing

Now create a shared folder on the server where all files/folders will be stored and set appropriate permissions on it and allow SELINUX for the samba configuration.

Run below commands

mkdir -p /srv/samba/anonymous
chmod -R 0755 /srv/samba/anonymous
chown -R nobody:nobody /srv/samba/anonymous
chcon -t samba_share_t /srv/samba/anonymous

Now make following changes in new samba configuration file.

# vi /etc/samba/smb.conf

[global]
workgroup = WORKGROUP
server string = Samba Server %v
netbios name = rhel8
security = user
map to guest = bad user
dns proxy = no

[Anonymous]
path = /srv/samba/anonymous
browsable =yes
writable = yes
guest ok = yes
read only = no

Run below commant to verify samba configurations

testparm

Start and Add Samba Services in firewall

Run below command to add samba service in firewall

firewall-cmd --permanent --add-service=samba
firewall-cmd --reload

start and enable samba services

systemctl start smb.service
systemctl enable smb.service
systemctl start nmb.service
systemctl enable nmb.service

Access Samba Share Path

Now open Run prompt by pressing win + r key on your keyboard then type \\rhel8 and press enter key.

You will see Anonymous folder like below

Now you can add files/folders in this folder to share with other users.

Create samba secure share 

Create a secured share on the server where only allowed user can login and set appropriate permissions on it and allow SELINUX for the samba configuration.

Create group for samba users

groupadd securedgroup

Create samba user with securedgroup

useradd demo -G securedgroup

Now create secure share folder for samba users and set necessary permissions.

mkdir -p /srv/samba/secured
chmod -R 0770 /srv/samba/secured
chcon -t samba_share_t /srv/samba/secured
chown -R root:securedgroup /srv/samba/secured/

Add user to samba database and set its password

smbpasswd -a demo

Now add following lines in samba configuration file.

vi /etc/samba/smb.conf

[secured]
path = /srv/samba/secured
valid users = @securedgroup
guest ok = no
writable = yes
browsable = yes

Then restart samba

systemctl restart smb.service

Now access secured share from Windows

Now you can access the RHEL 8 secured folder from windows, open Run prompt by pressing win + r key on your keyboard
Then type \\SAMBA-SERVER-IP and press enter key.

My samba server IP is 192.168.130.152 so i will use \\192.168.130.152

Now Click on secured folder and it will ask you to enter samba user login details to access the folder.

You will see secured folder like below, Now you can add files/folders in this folder to share with other samba users.

Mount and access Samba secure share from Linux

I am going to use Ubuntu to access RHEL 8 Samba secure share.
Login to Ubuntu, open terminal and run below command.

First install samba client

apt-get install samba-client -y

Now use below command to verify Samba Share is accessible.

smbclient --user=demo -L //192.168.130.152

Command Syntax:
smbclient –user=samba-username -L //Samba-Server-IP

Access/Mount Samba share

smbclient //192.168.130.152/secured -U demo

Command Syntax:
smbclient //Samba-Server-IP/share-name -U samba-username

That’s it you have accesses the samba shared from Windows and Linux successfully.
