There is a new version of this tutorial available for Ubuntu 16.04 (Xenial Xerus).

Samba Server Configuration in Ubuntu 14.04 LTS

This guide explains how to configure samba server in Ubuntu 14.04 with anonymous & secured samba servers. 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.

I do not issue any guarantee that this will work for you!

1 Preliminary Note

I have fresh installed ubuntu14.04 server, on which I am going to install the samba server. Off-course you need to have one windows machine to check the  samba server that must be reachable with the ubuntu server. My ubuntu server have hostname server1.example.com & IP as 192.168.0.100

You can have your ubuntu server installed from the starting eleven chapters of this tutorial.

Note:

• The Windows machine must be on same workgroup. To check the value in windows machine run the command at cmd prompt

net config workstation

It will be like this

• To make the windows machine reachable in windows proceed like this. In the run terminal & add  the entry of your server IP address

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

In my case it was like this, just save the values.

[...]
192.168.0.100 	server1.example.com	ubuntu	

2 Anonymous samba sharing

First I will explain the methodology to install the samba with the anonymous sharing. To install samba run,

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

It will install samba with version 4.1.6-Ubuntu.

Now to configure samba edit the file /etc/samba/smb.cnf before making changes I will make the backup of original file as  /etc/samba/smb.cnf.bak

mv /etc/samba/smb.cnf /etc/samba/smb.cnf.bak

Further give the entries like this

vi /etc/samba/smb.cnf

[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

mkdir -p /samba/anonymous

service smbd restart

Now you can access the ubuntu sharing in windows as follows:

From windows machine just browse the folder& try to create a text file, but you will get an error of permission denied.

Check the permission for the shared folder.

[email protected]:~# ls -l /samba/
total 4
drwxr-xr-x 2 root root 4096 May 27 18:17 anonymous
[email protected]:~#

To allow anonymous user give the permissions as follows;

[email protected]:~# cd /samba
[email protected]:/samba# chmod -R 0755 anonymous/
[email protected]:# chown -R nobody:nogroup anonymous/
[email protected]:/samba# ls -l
total 4
drwx-xr-x 2 nobody nogroup root 4096 May 27 18:17 anonymous
[email protected]:/samba#

Now anonymous user can browse & create the folder contents.

You can cross check the content at server also.

[email protected]:/samba# ls -l anonymous/
total 0
-rwxr--r-- 1 nobody nogroup 0 May 27 18:30 test_samba.txt
[email protected]:/samba#

3. Secured samba server

For this I will create a group smbgrp & user srijan to access the samba server with proper authentication

addgroup smbgrp

adduser srijan -G smbgrp

smbpasswd -a srijan

[email protected]:~# smbpasswd -a srijan
New SMB password:
Retype new SMB password:
Added user srijan.
[email protected]:~#

Now create the folder viz secured in the /samba folder & give permissions like this

mkdir -p /samba/secured
cd /samba
chmod -R 0770 secured/

Again edit the configuration file as :

vi /etc/samba/smb.conf

[secured]
 path = /samba/secured
 valid users = @smbgrp
 guest ok = no
 writable = yes
 browsable = yes

service smbd restart 

Further to cross-check the settings check as follows:

[email protected]:~# 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

Now at windows machine check the folder now with the proper credentials

You will again face the issue of permissions to give write permission to the user srijan do:

cd /samba
chown -R srijan:smbgrp secured/
