Samba is an open-source software suite that runs on Unix/Linux based platforms but is able to communicate with Windows clients like a native application. So Samba is able to provide this service by employing the Common Internet File System (CIFS). At the heart of this CIFS is the Server Message Block (SMB) protocol.
Here at LinuxAPT, as part of our Server Management Services, we regularly help our Customers to install Software on their Linux Servers.
In this context, we shall look into how to install and use Samba to share files on Ubuntu Linux distribution.
How to install Samba on Ubuntu 20.04 ?
Here, on your Ubuntu Server, log into your server as a root user with sudo privileges.

How to Share folders using Samba ?
Once the installation of Samba is completed, now we can share folders or directories graphically by using the default Ubuntu file manager tool 'Nautilus'.
Let's play a demo on how to share directories through the Nautilus file manager.
i. Go to the file manager and choose a folder that you want to share through your local network.
ii. Right-click on the required folder and then choose the 'Local Network Share' option from the displaying list items.
iii. The following folder sharing dialog will be displayed on the system. You need to mark the following checkboxes to share the directory.
iv. Check the 'Share this folder' checkbox and then, type the share name and you can also add a comment but, this is optional.
Only the owner of the share directory in the default Linux configuration can read or write to the files and directories in the Samba share.
v. Click on the 'Create Share' button.
vi. After that, you will see dialog box on your system. Click on the 'Add the permissions automatically'.
You will see that share is enabled now and ready to use. Now, close the folder sharing dialog by clicking on the cancel option.
Once you share a folder, the folder icon should be changed.
How to Create Samba users in Linux ?
If you are a guest user then, you don't need any user account authentication to access Samba shares directories. By using guest shares, everyone can access the sharing folder on the network. But, you need a Samba user account to allow access to Samba shares as an authorized person.
Note: you should know that local Linux server accounts are linked with the Samba user accounts. So, you can keep the same name of Samba users that matched with the local Linux server user's accounts.
For example, we are creating a Samba user named 'linuxapt' by running the following command:
$ sudo smbpasswd -a linuxapt
In the above command, the name 'linuxapt' is the name of my login user on Ubuntu.
Enter the new password for a user and press 'Enter'. Again, retype the new password and hit 'Enter'.
You will see on the terminal that the new Samba user is created successfully and a new password has been assigned to a newly created user.

$ sudo nano /etc/samba/smb.conf
v. Once the configuration file is loaded, add the following code at the end of the file:
path = /home/<user_name>/<folder_name>
valid users = <user_name>
read only = no
vi. Replace the user_name and folder_name with your own details.
