Configure Network Share via Samba CLI

Here we will learn how to create a network share via Samba using the command line interface in a easy, simple detailed way for network administrators targeting Windows users.

Procedures

Note: All commands must be done via root by using “sudo” in front of the command

  • Install Samba
    • sudo apt-get update
      sudo apt-get install samba
  • 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=

  • Create a directory to be shared
    mkdir /home/<user_name>/<folder_name>
  • 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 ~
  • 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>
      valid users = <user_name>
      read only = no

      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.

  • Restart the samba:
    sudo service smbd restart
  • Once Samba has restarted, use this command to check your smb.conf for any syntax errors
    testparm
  • To access your network share
          sudo apt-get install smbclient
          # List all shares:
          smbclient -L //<HOST_IP_OR_NAME>/<folder_name> -U <user>
          # connect:
          smbclient //<HOST_IP_OR_NAME>/<folder_name> -U <user>

    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".
