Just a stand alone server. The user on a Windows 7 user logs into a local Windows account. The username and password are the same on both the Ubuntu server and the Windows client.

This brief tutorial shows you how to uninstall or delete packages on Ubuntu 18.04 16.04 systemsIf you’re a student or new user looking for a Linux system to start learning on, the easiest place to start is on Ubuntu Linux OS.

The author selected the to receive a donation as part of the program. Introductionis an open-source implementation of the used in Windows environments for shared services such as file and printer access and Active Directory. Samba can also be used to create cross-platform file shares in a configuration called a standalone server.In this guide, you will install and configure a standalone Samba server to provide networked file stores or shares for a hypothetical small organization called Example.com. This organization has several requirements for their file shares: 1. Every employee needs a personal, private file share; 2. All employees should have read and write access to a common file share; 3.

An administrative user should have read and write access to all personal shares and ownership of the common share.Your Samba server will meet all of these requirements. You will also learn how to access the shares from Windows, Linux, and macOS. PrerequisitesBefore you begin this guide you’ll need the following:.An Ubuntu 16.04 server with a non-root sudo user. Please refer to the guide for more information. Samba has modest RAM and CPU requirements and will function well on a 1GB server. You are more likely to run out of storage space, so this should be your primary consideration when choosing your server size.Incoming TCP connections allowed on port 445.

If you are using the firewall, please refer to for guidance. If you are using a different or external firewall, please refer to the relevant documentation.Step 1 — Installing SambaLet’s start by installing Samba using Ubuntu’s package management system.Before installing new packages, let’s update the local package index to include the most up-to-date versions from the Ubuntu repositories:. sudo apt-get updateNext, install Samba:.

sudo apt-get install sambaThis command will install and start both the Samba server smbd and the Samba NetBIOS server nmbd. Nmbd is not required for this tutorial, so in the interests of security you can stop and disable it with systemctl:. sudo systemctl stop nmbd.service.

sudo systemctl disable nmbd.serviceThe sudo systemctl disable nmbd.service command will produce the following output when run. Output1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:002: eth0: mtu 1500 qdisc pfifofast state UP mode DEFAULT group default qlen 1000link/ether 02:21:2c:03:ef:e2 brd ff:ff:ff:ff:ff:ffThis output indicates that lo is the loopback interface and eth0 is the external network interface, though your external interface may differ. Take note of both: you’ll include them with the interfaces directive in the global section of the smb.conf file.Let’s begin editing this file with nano or your favorite editor:. sudo nano /etc/samba/smb.confThe global section of this file will define the server’s name, role, and other details, including network interfaces. /etc/samba/smb.conf globalserver string = sambaserverserver role = standalone serverinterfaces = lo yournetworkinterfacebind interfaces only = yesdisable netbios = yessmb ports = 445log file = /var/log/samba/smb.logmax log size = 10000These directives specify the following:.

server string - This is the identifying information that will be supplied to users during connections. You can use sambaserver or another name that will identify your server. Throughout this tutorial, you will see the string samba.example.com to denote the Samba share for the organization Example.com.

server role - This defines what type of Samba server will be created. In this case it is a standalone server, i.e.

A file share. Other server types include domain member servers and domain controllers. interfaces - These are the network interfaces that Samba will bind to. Lo is the loopback interface (127.0.0.1) and is required. You will also need to include the external network interface you outputted earlier. This is usually eth0. bind interfaces only - This ensures that Samba only binds to the interfaces listed on the interfaces line.

As a security measure, this causes Samba to ignore packets that do not correspond to the specified interfaces. disable netbios - This disables all NetBIOS functions that are not needed in a standalone server.

Doing this simplifies the server name resolution process and the transport of SMB traffic. smb ports - This sets the port that Samba will listen on. Port 445 is the standard port for Samba.

log file - This sets the name and location of Samba’s log file. max log size - This sets a size limit on the log file. The number listed is in bytes and equals 10MB. Some things to keep in mind when setting this size limit: When it is reached, Samba will generate a new log file and move the old contents to a duplicate with an.old extension. If the limit is exceeded again, the existing.old file will be destroyed.

This prevents disk/partition space from being overwhelmed with the contents of a single log file. You should therefore define a file size that makes sense for your system resources.If you want more detailed logging while you are setting up the server, append the following line to the global section. /etc/samba/smb.conf log level = 3 passdb:5 auth:5This sets the log level to 3 (info), increasing the granularity of log information from the default setting of 1. The higher setting of 5 for the passdb and auth debug classes provides more information related to user authentication.Save and close the file when you have finished creating this section.Whenever you edit smb.conf, you should run the Samba utility testparm to check that there are no syntax errors:. testparmRunning the testparm command on the smb.conf file produces the following output.

Output# Global parametersglobalserver string = sambaserverinterfaces = lo yournetworkinterfacebind interfaces only = Yesserver role = standalone serverlog file = /var/log/samba/smb.logmax log size = 10000smb ports = 445disable netbios = Yesidmap config.: backend = tdbIf testparm reports Loaded services file OK., then there are no syntax errors that would stop the Samba server from starting.Configuring the global section is all that’s required to start the Samba server. However, its functionality will be limited without share configurations. A share is comprised of two parts, a user and a directory, both of which must be created and configured to allow logins and testing. The next section will explain how to create users that can access the shares.

Step 3 — Creating UsersIn this step, we will create users that can access the shares. They will need access as Samba and system users in order to authenticate with the Samba server when they log in and read and write to the file system.In the hypothetical company Example.com there are four employees who need to be added to the Samba server and created as users on the Linux system: david, mike, jane, and lucy.

In addition to these four, there will be an admin user who will be able to access and administer the personal shares. This user will also own the common shares that everyone can access.The first step to adding system users is creating home directories for each of them. Rather than using the standard home directories at /home/user, the Samba directories and data will be located at /samba/. Keeping Samba data in a single location and separated from other user data will make future management tasks such as backups easier.Note: The users created in this guide are not intended to have SSH logins. If your users already have accounts on the server, you should create a dedicated Samba user for them in order to follow this guide.The next section will explain the process to add the first user, david, but you will need to repeat this process for mike, jane, and lucy.The first step is to create the directory where the Samba data will be stored, at the root of the file system. /etc/samba/smb.conf. sharenamepath =browseable =read only =force create mode =force directory mode =valid users =These options include:.

sharename - This is the name of the share that you will use when logging in. path - This is the absolute path to the share in the filesystem. browsable - This sets whether or not other users are able to see the share. Enabling this option only allows other users of the Samba server to see the existence of the share. It does not confer any read or write permissions. read only - This sets whether the valid users are able to write to the share. force create mode - This forces the permissions for any file written to the share.

force directory mode - This forces the permissions for any directory created in the share. valid users - This is a list of the users who have access to the share. This setting can take usernames or system groups such as admins. Groups must be listed with an @ in front e.g. @admins.Add the following share configuration block for david, defining his home directory, the permissions for this directory’s group ownership, and the users that should have access to his share. /etc/samba/smb.conf davidpath = /samba/davidbrowseable = noread only = noforce create mode = 0660force directory mode = 2770valid users = david @adminsNote that the directory permissions set the group ownership to that of the parent directory.Create a share block for mike, jane, and lucy.

Change only the share name, path, and valid users to reflect each of the user’s names.The everyone share will differ from the others in both name, path, valid users, and browsable options, and will look like this. OutputLoad smb config files from /etc/samba/smb.confrlimitmax: increasing rlimitmax (1024) to minimum Windows limit (16384)Processing section 'david'Processing section 'jane'Processing section 'mike'Processing section 'lucy'Processing section 'everyone'Loaded services file OK.Server role: ROLESTANDALONEPress enter to see a dump of your service definitionsWith the configuration check complete, let’s start the Samba server with systemctl:.

sudo systemctl start smbd.serviceThe Samba server is now running and ready to accept logins. The next step is to log into the Samba server to test that it is working as expected. The following section will cover logging into the Samba server from Windows, Linux, and macOS.

Step 5 — Logging Into the Samba ServerIn this section, we will cover how to access the Samba shares we created from Linux, Windows, and macOS. Linux — The Command LineYou can use a tool called smbclient to access Samba from the command line. This package is not included by default on most Linux distributions, so you will need to install it with your local package manager.On Debian and Ubuntu servers install smbclient with the following command:.

sudo apt-get update. sudo apt-get install smbclientOn Fedora systems, use the following:. sudo dnf update.

sudo samba-clientAnd on CentOS:. sudo yum update. sudo yum install samba-clientNote: On some Linux distributions smbclient will fail with the following error message. Outputsmbclient: Can't load /etc/samba/smb.conf - run testparm to debug itIf you see this error message, check to be sure that you have created the file at /etc/samba/smb.conf.smbclient uses the following format to access Samba shares:. smbclient // yoursambahostnameorserverip/ share -U usernameYou can use either your server’s IP or the hostname you defined in /etc/samba/smb.conf to access the share. This example uses the hostname samba.example.com to access david’s share on the Samba server you created in the previous steps:.

smbclient // samba.example.com/ david -U davidIf david wants access to the common share ( everyone), change the command to:. smbclient // samba.example.com/ everyone -U davidAfter running the smbclient command, you will be prompted for the Samba password and logged into a command line interface reminiscent of the FTP text interface: smb: This interface is most useful for testing usernames and passwords and read-write access. For example, you can create a directory and list its contents as follows:. mkdir test.

lsYou should see the following output. D 0 Fri Feb 2 14. D 0 Wed Jan 24 12:test D 0 Fri Feb 2 14:Remove the directory by typing:. rmdir testManaging data in a share is often easier with a GUI tool. The next section will look at the built-in GUI tools for KDE. Linux — KDE with DolphinDolphin is the default file manager in KDE and has built-in functionality to access Samba shares.After opening Dolphin, take the following steps:. Select Network from the Places list.

Click on Add Network Folder. Select the Microsoft Windows network drive option. Click Next. Enter the details for the Samba share:. Name - This is a memorable name that will be displayed as a bookmark in Dolphin for the share. Server - This is the hostname or IP address of the Samba server.

In this example it will be samba.example.com. Folder - This is the name of the share that was set in smb.conf. Click Save & Connect. Enter the username and password for the user you are going to access the Samba share with. Click OK.Dolphin will now connect and open the Samba share which will look like this:You can now use the Samba share as if it were a local directory to copy, delete, and rename files and directories. The share will also appear as a permanent bookmark in the Network places. MacOS — The Command LineMacOS comes pre-installed with command line tools you can use to access a Samba share.

Open the terminal with Launchpad by clicking on the Terminal icon.This will open a command line terminal in your home directory. To mount the Samba share, you can create a new directory that will act as the mount point for the share. A mount point is the location where two file systems are joined: in this case, your local file system and the remote Samba file system.Create a new directory called samba:. mkdir sambaNext, mount the Samba share under the new samba directory.

This command has the form:. sudo mountsmbfs // username@ yoursambahostnameorserverip/ share./ mountpointSubstituting the details from Example.com with user david looks like this:. sudo mountsmbfs // david@ samba.example.com/ david./ sambaThe samba directory will now show the contents of the david share on the Example.com Samba server. Files and directories can be manipulated with the normal tools such as ls, rm, and mkdir; however, the samba directory will be owned by root after the share has been mounted. You will therefore need to use sudo to access the samba directory and its contents.To unmount the Samba share, run the umount command from the same directory where you ran the mkdir command:. umount sambaThe next section will look at accessing a Samba share using the desktop GUI application in macOS. OutputEnter the user name for ' samba.example.com': davidEnter the password for samba.example.com:The command completed successfully.You will now be able to browse the Samba share in File Explorer and manipulate the files and directories as if they were local to your computer.The next section will look at using Windows GUI tools to access a Samba share.

Windows 10 — DesktopWindows 10 also has the native ability to connect to a Samba share. The following steps will connect you to your Samba share and keep it as a bookmark using Windows File Explorer. Begin these steps by opening File Explorer:. Right click on This PC.

Click on Add a network location and then Next on the page that follows. Click on Choose a custom network location. Greyhound skill crane manual online. Click Next. Enter the Windows style address of the Samba server and the share name. Windows uses the following form of a Samba URL: yoursambahostnameorserverip share.In the example image the server name is samba.example.com and the share name is david: samba.example.com david. Click Next.

Enter the username and password for the user. Decide whether or not you want Windows to remember the password. Click OK.File Explorer will now connect to the Samba share. Once the connection has successfully completed, a new location will be created under This PC in File Explorer:You will now be able to use this folder to manage files and folders in the Samba share as if it were a local folder. ConclusionIn this article, you have created cross-platform online file shares using the Samba server.

You have also accessed these shares from Windows, Linux, and macOS.Samba shares have become so common that many applications are able to access the data stored in them. These applications can extend the functionality and usefulness of your Samba shares. For example, the mobile version of the media player can connect to and stream music and video from your Samba share. To access it, select open MRL and use the standard Samba URL: smb:// username@ yoursambahostnameorserverip/ share. You can also use a Samba share as the destination for your backups with the cross-platform backup utility.In addition to acting as a simple file share, Samba can work with Windows Active Directory as either a domain controller or a member of a domain.

The Samba Wiki contains more information on how to do this.
