This guide explains the installation and configuration of a Samba server on Ubuntu 16.04 (Xenial Xerus) with anonymous and secured Samba shares. Samba is an Open Source/Free Software suite that provides seamless file and print services to SMB/CIFS clients. Samba is freely available, unlike other SMB/CIFS implementations, and allows for interoperability between Linux/Unix servers and Windows-based clients.
1 Preliminary Note
I have fresh installed Ubuntu 16.04 server, on which I am going to install the samba server. As Samba client system, I will use a Windows Desktop to connect to the samba server and check the setup. The Windows Desktop should be in the same network so that it is able to reach the Ubuntu server. The hostname of my Ubuntu server is server1.example.com and the IP is 192.168.1.100
If you don't have a Ubuntu server already, follow this tutorial to get a minimal server setup as the basis for this tutorial.
Note: The Windows machine must be in the same workgroup. To check the value in the Windows machine run the following command at cmd prompt:
net config workstation
The output will be like this:
Your Windows machine must be in the same Workstation domain as the Ubuntu server, i.e. WORKGROUP in my case.
To make the windows machine reachable in Windows by its hostname, proceed like this. Open a Windows terminal in administrator mode (you can reach the administrator mode by doing a right-click on the Terminal icon in the program menu) and run the following command to open the Windows hosts file:
There you add the following red line and save the file:
192.168.1.100 server1.example.com server1
The following steps have to be run as root user. Run:
on the shell of your Linux server to become the root user.
2 Anonymous Samba sharing
Samba is available in the Ubuntu repositories. The first step is to install the Samba Server and its dependencies with apt.
apt-get install -y samba samba-common python-glade2 system-config-samba
It will install the Samba version 4.3.9-Ubuntu.
To configure samba, edit the file /etc/samba/smb.conf. I will use nano as editor and make a backup of the original file before I start to change it. The backup file is named /etc/samba/smb.conf.bak
cp -pf /etc/samba/smb.conf /etc/samba/smb.conf.bak
cat /dev/null > /etc/samba/smb.conf
Open the Samba configuration file with nano:
And add the following lines.
[global] workgroup = WORKGROUP server string = Samba Server %v netbios name = ubuntu security = user map to guest = bad user dns proxy = no
#============================ Share Definitions ==============================
[Anonymous] path = /samba/anonymous browsable =yes writable = yes guest ok = yes read only = no
force user = nobody
Then I'll create a directory for the anonymous share.
mkdir -p /samba/anonymous
Set the correct permissions.
chmod -R 0775 /samba/anonymous
chown -R nobody:nogroup /samba/anonymous
And restart Samba to apply the new configuration.
service smbd restart
Now you can access the Ubuntu sharing in Windows by entering "\\server1" in the windows search field of the menu or use the network browser of the Windows file explorer to connect to the share.
Try to upload a file by Drag&Drop to the share to see if it is working correctly.
You can cross check the content at server also.
ls -la /samba/anonymous/
[email protected]:/samba/anonymous# ls -la /samba/anonymous/
drwxrwxr-x 2 nobody nogroup 4096 Jun 1 18:46 .
drwxr-xr-x 3 root root 4096 Jun 1 18:39 ..
-rwxr--r-- 1 nobody nogroup 7405 Jun 1 18:42 test.odt
3 Secured Samba server
For the password-protected share, I will create a group smbgrp and user till to access the Samba server. I'll use "howtoforge" as password in this example, please choose a custom and secure password on your server.
useradd till -G smbgrp
smbpasswd -a till
Now create the folder with the name "secured" in the /samba folder and give permissions like this
mkdir -p /samba/secured
chmod -R 0770 secured
chown root:smbgrp secured
Edit the Samba configuration file and add the following (red) lines at the end of the file:
[secured] path = /samba/secured valid users = @smbgrp guest ok = no writable = yes browsable = yes
service smbd restart
To cross-check the settings, run this command:
[email protected]:/samba# testparm
Load smb config files from /etc/samba/smb.conf
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)
Processing section "[Anonymous]"
Processing section "[secured]"
Loaded services file OK.
Server role: ROLE_STANDALONE
Press enter to see a dump of your service definitions <-- Press Enter
# Global parameters
netbios name = UBUNTU
server string = Samba Server %v
security = USER
map to guest = Bad User
dns proxy = No
idmap config * : backend = tdb
path = /samba/anonymous
force user = nobody
read only = No
guest ok = Yes
path = /samba/secured
valid users = @smbgrp
read only = No
At the Windows machine, open the "\\server1" network device again, it will request a username and password now. Enter the user details that you created above. In my case, the values were user=till and password=howtoforge.
We can check the file at the Ubuntu server like this:
ls -la /samba/secured/
[email protected]:/samba# ls -la /samba/secured/
drwxrwx--- 2 root smbgrp 4096 Jun 1 19:25 .
drwxr-xr-x 4 root root 4096 Jun 1 18:49 ..
-rwxr--r-- 1 till till 7405 Jun 1 18:42 test.odt
Now we have a successfully configured Samba server with an anonymous and a secured share on Ubuntu 16.04 :)
