This guide explains how to configure samba server in OpenSuse 13.2 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.

1 Preliminary Note

I have fresh installed OpenSuse 13.2 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 OpenSuse 13.2 server. My OpenSuse 13.2 server have hostname server1.example.com & IP as 192.168.0.100

You can have your OpenSuse 13.2 server installed from the starting five chapters of the 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	opensuse 	

2 Anonymous samba sharing

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

zypper install samba samba-client

It will ask for your input

server1:~ # zypper install samba samba-client

Problem: patterns-openSUSE-minimal_base-conflicts-13.2-13.6.1.x86_64 conflicts with samba-client provided by samba-client-4.1.6-3.18.1.x86_64
 Solution 1: Following actions will be done:
  do not install samba-client-4.1.6-3.18.1.x86_64
  do not install samba-4.1.6-3.18.1.x86_64
 Solution 2: deinstallation of patterns-openSUSE-minimal_base-conflicts-13.2-13.6.1.x86_64

41 new packages to install, 1 to remove.
Overall download size: 11.1 MiB. After the operation, additional 32.4 MiB will
be used.
Continue? [y/n/? shows all options] (y): <--y

It will install samba with Version 4.1.6-3.18.1-3208-SUSE-oS13.2-x86_64

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

cp /etc/samba/smb.conf /etc/samba/smb.conf.bak
cat /dev/null  > /etc/samba/smb.conf

Further give the entries like this

vi /etc/samba/smb.cnf

[global]
      
workgroup = WORKGROUP
passdb backend = tdbsam
server string = Samba Server %v
netbios name = opensuse 
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

Next add the services in boot, and start the service as:

systemctl start smb.service
systemctl start smb.service

Note: we need to allow the services to get beyond the Firewall, so we will add the services in yast2 as:

yast2

Allow the services override in firewall for Samba Client and Samba Server.

Now you can access the OpenSuse 13.2 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.

ls -l /samba/

server1:~ # ls -l /samba/
total 0
drwxr-xr-x 1 root root 0 Nov 11 09:41 anonymous
server1:~ #

To allow anonymous user give the permissions as follows;

cd /samba
chmod -R 0777 anonymous/
ls -l

server1:/samba # ls -l
total 0
drwxrwxrwx 1 root root 0 Nov 11 09:41 anonymous
server1:/samba #

Now anonymous user can browse & create the folder contents.

You can cross check the content at server also.

ls -l anonymous/

server1:/samba # ls -l anonymous/
total 0
-rwxr--r-- 1 nobody nobody 0 Nov 21 14:10 anonymous_test.txt
server1:/samba #

3. Secured samba server

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

groupadd smbgrp

useradd srijan -G smbgrp

smbpasswd -a srijan

server1:~ # smbpasswd -a srijan
New SMB password:
Retype new SMB password:
Added user srijan.
server1:~ #

server1:/samba # smbpasswd -a srijan
New SMB password: <--srijanpasswd
Retype new SMB password: <--srijanpasswd
Added user srijan.
server1:/samba #

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

systemctl restart smb.service

Further to cross-check the settings check as follows:

testparm

server1:~ # 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

[global]
    netbios name = OPENSUSE
    server string = Samba Server %v
    map to guest = Bad User
    dns proxy = No
    idmap config * : backend = tdb

[Anonymous]
    path = /samba/anonymous
    read only = No
    guest ok = Yes

[secured]
    path = /samba/secured
    valid users = @smbgrp
    read only = No
server1:~ #

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/

ls -l /samba/secured/

server1:~ # ls -l /samba/secured/
total 0
-rwxr--r-- 1 srijan users 0 Nov 21 14:16 secured_test.txt
server1:~ #

Cheers now we have a successfully configured samba server over OpenSuse 13.2 :)
