How to install Samba server on CentOS 6

Part 1: Configuring anonymous share with samba server

To install the samba package,enter the following command:

sudo yum install samba samba-client samba-common

Check the version of installed samba software by using this command:

smbd --version

Configure the samba service, so that, it will start automatically at boot time:

sudo chkconfig smb on

sudo chkconfig nmb on

Disable the SELinux:

sudo nano /etc/selinux/config

Change SELinux from enforcing to disabled:

SELINUX=disabled

Add these Iptables rules, so that samba will work perfectly:

sudo iptables -I INPUT 4 -m state --state NEW -m udp -p udp --dport 137 -j ACCEPT

sudo iptables -I INPUT 5 -m state --state NEW -m udp -p udp --dport 138 -j ACCEPT

sudo iptables -I INPUT 6 -m state --state NEW -m tcp -p tcp --dport 139 -j ACCEPT

sudo service iptables save

Restart the Server!!!

Go to your Windows machine and use this command in order to check the WORKGROUP name:

net config workstation

It will show the output, something like this:

Backup the smb.conf file, then delete it and create the new one:

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

sudo rm /etc/samba/smb.conf

sudo touch /etc/samba/smb.conf

sudo nano /etc/samba/smb.conf

Add these lines, in your smb.conf file (or change it according to your requirement):

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

[global]

 workgroup = WORKGROUP

 security = share

 map to guest = bad user

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

[MyShare]

 path = /samba/share

 browsable =yes

 writable = yes

 guest ok = yes

 read only = no

Save the smb.conf file and restart the service:

sudo service smb restart

sudo service nmb restart

Access the samba share from windows (where centos is the name of my samba server):

wao, we are able to access the samba share successfully 

Let’s try to create something, inside the share folder:

Error, we cannot create anything inside the share folder 

Check the current permission on the samba share:

cd /samba/

ls -l

Change it, in such a way that everyone can read and write it(Check it, that it is allowed in your environment or not):

sudo chmod -R 0777 share

ls -l

Try to create something again, inside the share folder:

Verify the newly created file on samba server:

cd share/

ls -l

Part 2: Add and manage users and groups

Add a group in your CentOS server (in my case smbgrp):

sudo groupadd smbgrp

Create a new share, set the permission on the share:

cd /samba/

sudo mkdir secure

sudo chown -R arbab:smbgrp secure/ 

ls -l 

sudo chmod -R 0770 secure/

ls -l

Add the user to the samba group and create samba password:

sudo usermod -a -G smbgrp arbab

sudo smbpasswd -a arbab

Edit the smb.conf file:

sudo nano /etc/samba/smb.conf

Add the newly created samba share in smb.conf file:

[Secure]

path = /samba/secure

 valid users = @smbgrp

 guest ok = no

 writable = yes

 browsable = yes

Restart the samba service:

sudo service smb restart

sudo service nmb restart

Check the syntax error with testparm:

sudo testparm

Testing from Windows Machine:

Verification from CentOS server:

cd /samba/secure/

ls -l
