1. install Samba 
    sudo apt-get update
sudo apt-get install samba
  2. Set a password for your user in Samba 
    • sudo smbpasswd -a <user_name>
      • Note: Samba uses a separate set of passwords than the standard Linux system accounts (stored in /etc/samba/smbpasswd), so you'll need to create a Samba password for yourself. This tutorial implies that you will use your own user and it does not cover situations involving other users passwords, groups, etc...

         

        Tip1: Use the password for your own user to facilitate.

         

        Tip2: Remember that your user must have permission to write and edit the folder you want to share.
Eg.:
sudo chown <user_name> /var/opt/blah/blahblah
sudo chown :<user_name> /var/opt/blah/blahblah

         

        Tip3: If you're using another user than your own, it needs to exist in your system beforehand, you can create it without a shell access using the following command :
sudo useradd USERNAME --shell /bin/false

You can also hide the user on the login screen by adjusting lightdm's configuration, in /etc/lightdm/users.conf add the newly created user to the line :
hidden-users=

         

  3. Create a directory to be shared [optional] 
    mkdir /home/<user_name>/<folder_name>
  4. Make a safe backup copy of the original smb.conf file to your home folder, in case you make an error 
    sudo cp /etc/samba/smb.conf ~
  5. Edit the file “/etc/samba/smb.conf” 
    sudo nano /etc/samba/smb.conf
    • Once "smb.conf" has loaded, add this to the very end of the file:

[<folder_name>]
path = /home/<user_name>/<folder_name>
available = yes
valid users = <user_name>
read only = no
browseable = yes
public = yes
writable = yes

       

      Tip: There Should be in the spaces between the lines, and note que also there should be a single space both before and after each of the equal signs.

       

  6. Restart the samba: 
    sudo service smbd restart
  7. Once Samba has restarted, use this command to check your smb.conf for any syntax errors 
    testparm
  8. To access your network share

    To access your network share use your username (<user_name>) and password through the path “smb://<HOST_IP_OR_NAME>/<folder_name>/” (Linux users) or “\\<HOST_IP_OR_NAME>\<folder_name>\” (Windows users). Note that “<folder_name>” value is passed in “[<folder_name>]”, in other words, the share name you entered in “/etc/samba/smb.conf”.

    • Note: The default user group of samba is "WORKGROUP".
  9. Now from GUI go to any directory.
  10. Right click on it > go to Properties.
  11. Click “Local Network Share” > Click “Share this folder” > click “Create share” at the right bottom.
  12. Now it is done.
  13. Go from any network PC and hit the ip address.
  14. Use user/pass (samba) and happy Browsing!! đŸ™‚
