Students Tutorial – Samba Filesharing Between Windows 10 and Ubuntu 16.10

Here’s a simple tutorial that shows students and new users how to share file between Windows 10 and Ubuntu 16.10 via Samba.

Samba is an open source software that provides seamless file and print services to SMB/CIFS clients. Since Windows uses CIFS services, Samba can be a great tool to enable file and print sharing between Windows and Linux systems.

This tutorial assumes you have both Windows and Ubuntu machines on the same subnet. For this tutorial, our subnet is going to be

The Windows machine will have IP address and the Linux machine

Both machine will also be in the same local workgroup. You can name the workgroup whatever you want, but for this post, our workgroup will be the default Windows workgroup called WORKGROUP

Windows IP address ===========>
Ubuntu IP address ============>
Workgroup Name ============> WORKGROUP

Both the Windows and Ubuntu machines will be member of the local workgroup called WORKGROUP

Step 1: Find Windows Workgroup name

The first thing we’ll want to do is to find the Windows computer workgroup name. We’ll then add Ubuntu to the same local workgroup. To find out that info on Windows machine, open the command prompts and type the commands below

net config workstation

When you run the commands above, you should see your current computer workgroup.

windows computer workgroup

Step 2: Add Ubuntu machine IP to Windows local host file.

Since we’re not going to be using a DNS systems, let’s add Ubuntu IP address and server name to Windows host file so we can reference the Ubuntu computer via its name. To do that, open Windows command prompts as administrator, then run the commands below to open the host file.

notepad C:\\Windows\System32\drivers\etc\hosts

Next, type the info for the Ubuntu machine.              ubuntu1610.localhost     ubuntu1016

Save your changes and you’re done.

Step 3: Install Samba on Ubuntu 16.10

At this point, you should know your Windows workgroup name and have the Ubuntu machine IP address and hostname in Windows machine local host file.

Next, logon on to the Ubuntu machine to install Samba. To install Samba, run the commands below.

sudo apt-get install samba samba-common python-glade2 system-config-samba

After installing Samba, go and config Samba.

Step 4: Configure Samba Public share

Now that Samba is installed, run the commands below to backup its default configuration file.

sudo cp -pf /etc/samba/smb.conf /etc/samba/smb.conf.bak

Next, open Samba configuration file by running the commands below.

sudo nano /etc/samba/smb.conf

Then make the changes as highlighted below. Important: comment out [# or ; ]  all lines except highlighted lines in red shown below:

To create a public share where everyone has access, include the highlighted section in the file and save.

# Sample configuration file for the Samba suite for Debian GNU/Linux.
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which 
# are not shown in this example
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
#  - When such options are commented with ";", the proposed setting
#    differs from the default Samba behaviour
#  - When commented with "#", the proposed setting is the default
#    behaviour of Samba but the option is considered important
#    enough to be mentioned here
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic 
# errors. 

#======================= Global Settings =======================


## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of
   workgroup = WORKGROUP

# server string is the equivalent of the NT Description field
   server string = Samba Server %v

# Security
   security = user

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
#   wins support = no

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
;   wins server = w.x.y.z

   name resolve order = bcast host

# This will prevent nmbd to search for NetBIOS names through DNS.
   dns proxy = no

#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
;   interfaces = eth0

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself.  However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
;   bind interfaces only = yes

#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine
# that connects
   log file = /var/log/samba/log.%m

# Cap the size of the individual log files (in KiB).
;   max log size = 1000

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
#   syslog only = no

# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.
   syslog = 0

# Do something sensible when Samba crashes: mail the admin a backtrace
;   panic action = /usr/share/samba/panic-action %d

####### Authentication #######

# Server role. Defines in which mode Samba will operate. Possible
# values are "standalone server", "member server", "classic primary
# domain controller", "classic backup domain controller", "active
# directory domain controller". 
# Most people will want "standalone sever" or "member server".
# Running as "active directory domain controller" will require first
# running "samba-tool domain provision" to wipe databases and create a
# new domain.
;   server role = standalone server

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using.  
;   passdb backend = tdbsam

;   obey pam restrictions = yes

# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
;   unix password sync = yes

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<> for
# sending the correct chat script for the passwd program in Debian Sarge).
;   passwd program = /usr/bin/passwd %u
;   passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.
;   pam password change = yes

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections
   map to guest = bad user

########## Domains ###########

# The following settings only takes effect if 'server role = primary
# classic domain controller', 'server role = backup domain controller'
# or 'domain logons' is set 

# It specifies the location of the user's
# profile directory from the client point of view) The following
# required a [profiles] share to be setup on the samba server (see
# below)
;   logon path = \\%N\profiles\%U
# Another common choice is storing the profile in the user's home directory
# (this is Samba's default)
#   logon path = \\%N\%U\profile

# The following setting only takes effect if 'domain logons' is set
# It specifies the location of a user's home directory (from the client
# point of view)
;   logon drive = H:
#   logon home = \\%N\%U

# The following setting only takes effect if 'domain logons' is set
# It specifies the script to run during logon. The script must be stored
# in the [netlogon] share
# NOTE: Must be store in 'DOS' file format convention
;   logon script = logon.cmd

# This allows Unix users to be created on the domain controller via the SAMR
# RPC pipe.  The example command creates a user account with a disabled Unix
# password; please adapt to your needs
; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u

# This allows machine accounts to be created on the domain controller via the 
# SAMR RPC pipe.  
# The following assumes a "machines" group exists on the system
; add machine script  = /usr/sbin/useradd -g machines -c "%u machine account" -d /var/lib/samba -s /bin/false %u

# This allows Unix groups to be created on the domain controller via the SAMR
# RPC pipe.  
; add group script = /usr/sbin/addgroup --force-badname %g

############ Misc ############

# Using the following line enables you to customise your configuration
# on a per machine basis. The %m gets replaced with the netbios name
# of the machine that is connecting
;   include = /home/samba/etc/smb.conf.%m

# Some defaults for winbind (make sure you're not using the ranges
# for something else.)
;   idmap uid = 10000-20000
;   idmap gid = 10000-20000
;   template shell = /bin/bash

# Setup usershare options to enable non-root users to share folders
# with the net usershare command.

# Maximum number of usershare. 0 (default) means that usershare is disabled.
;   usershare max shares = 100

# Allow users who've been granted usershare privileges to create
# public shares, not just authenticated ones
;   usershare allow guests = yes

#======================= Share Definitions =======================

# Un-comment the following (and tweak the other settings below to suit)
# to enable the default home directory shares. This will share each
# user's home directory as \\server\username
   path = /samba/public
   browseable = yes
   writable = yes
   guest ok = yes
   read only = no
   force user = nobody

# By default, the home directories are exported read-only. Change the
# next parameter to 'no' if you want to be able to write to them.
;   read only = yes

# File creation mask is set to 0700 for security reasons. If you want to
# create files with group=rw permissions, set next parameter to 0775.
;   create mask = 0700

# Directory creation mask is set to 0700 for security reasons. If you want to
# create dirs. with group=rw permissions, set next parameter to 0775.
;   directory mask = 0700

# By default, \\server\username shares can be connected to by anyone
# with access to the samba server.
# Un-comment the following parameter to make sure that only "username"
# can connect to \\server\username
# This might need tweaking when using external authentication schemes
;   valid users = %S

# Un-comment the following and create the netlogon directory for Domain Logons
# (you need to configure Samba to act as a domain controller too.)
;   comment = Network Logon Service
;   path = /home/samba/netlogon
;   guest ok = yes
;   read only = yes

# Un-comment the following and create the profiles directory to store
# users profiles (see the "logon path" option above)
# (you need to configure Samba to act as a domain controller too.)
# The path below should be writable by all users so that their
# profile directory may be created the first time they log on
;   comment = Users profiles
;   path = /home/samba/profiles
;   guest ok = no
;   browseable = no
;   create mask = 0600
;   directory mask = 0700

;   comment = All Printers
;   browseable = no
;   path = /var/spool/samba
;   printable = yes
;   guest ok = no
;   read only = yes
;   create mask = 0700

# Windows clients look for this share name as a source of downloadable
# printer drivers
;   comment = Printer Drivers
;   path = /var/lib/samba/printers
;   browseable = yes
;   read only = yes
;   guest ok = no
# Uncomment to allow remote administration of Windows print drivers.
# You may need to replace 'lpadmin' with the name of the group your
# admin users are members of.
# Please note that you also need to set appropriate Unix permissions
# to the drivers directory for these users to have write rights in it
;   write list = root, @lpadmin

Save your change

Step 5: Create the Public folder to share

Now that Samba is configured and the share folder block is added, go and create the folder you want to share. To do that, run the commands below.

sudo mkdir -p /samba/public

Set the permissions so that everyone can read and write to it.

sudo chown -R nobody:nogroup /samba/public
sudo chmod -R 0775 /samba/public

Restart Samba and open Windows File Explorer to view the shared location on Ubuntu

sudo service smbd restart

Now go to your Windows machine and you should see the shared Public folder on Ubuntu from the Windows machine.

ubuntu samba share

Everyone should have access there.

Step 5: Configure Samba Private Share

Now you know how to create Samba public shares, let’s go and create private and protected shares. Only users that are member of a group will be able to access the secure location with passwords.

First create a samba group called smbgroup for the share.. only members will have access. To create a groups in Ubuntu, run the commands below.

sudo addgroup smbgroup

Then add a user to the group by running the commands below

sudo adduser richard -G smbgroup

Finally, all users who need to access a protected samba share will need to type a password. To add a user to samba password database, run the commands below for each user.

sudo smbpasswd -a richard

The user will be prompted to enter and confirm a password. This password will be used to access the protected samba shares.

Next, go and create a protected share in the /samba directory.

sudo mkdir -p /samba/protected

Then give only root and members group access to this share.

cd /samba/
sudo chown -R root:smbgroup protected
sudo chmod -R 0770 protected

When you’re done creating the protected share, go and share it in the smb.conf file.

The add configuration block below into smb.conf file just below the one above

  path = /samba/protected
  valid users = @smbgroup
  guest ok = no
  writable = yes
  browsable =yes

Save your changes and you’re done.

Restart Samba and test your changes.

sudo service smbd restart

You should now see two folders… one is protected

samba windows shares

Many more shares can be defined using the format above.
