Easy Samba server installation on CentOS 6.5

Samba is a client/server system that implements network resource sharing for Linux and other UNIX computers. With Samba, UNIX files and printers can be shared with Windows clients and vice versa. Samba supports the Session Message Block (SMB) protocol. Nearly all Windows computers include SMB support with their internal network subsystems (NetBIOS in particular).
With an appropriately-configured Samba server on Linux, Windows clients can map drives to the Linux filesystems. Likewise, the Samba client on UNIX can connect to Windows shares by their UNC name. Although differences among various operating systems (such as filesystem naming conventions, end-of-line conventions, and authentication) can limit interoperability, Samba offers a generally serviceable mechanism for resource sharing on a heterogenous network.

Install Samba on CentOS 6.0/6.1/6.2/6.3/6.4/6.5

To install the samba package,enter the following command:

# yum install samba samba-client samba-common

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

# smbd --version
Check Samba version
Check Samba version

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

# chkconfig smb on
# chkconfig nmb on

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

# iptables -I INPUT 4 -m state --state NEW -m udp -p udp --dport 137 -j ACCEPT
# iptables -I INPUT 5 -m state --state NEW -m udp -p udp --dport 138 -j ACCEPT
# iptables -I INPUT 6 -m state --state NEW -m tcp -p tcp --dport 139 -j ACCEPT
# service iptables save

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

# cp /etc/samba/smb.conf /etc/samba/smb.conf.bak
# rm /etc/samba/smb.conf
# touch /etc/samba/smb.conf
# nano /etc/samba/smb.conf

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

#======================= Global Settings =====================================
workgroup = WORKGROUP
security = share
map to guest = bad user
#============================ Share Definitions ==============================
path = /home/samba/share
browsable =yes
writable = yes
guest ok = yes
read only = no

Save the smb.conf file and restart the service:

# service smb restart
# service nmb restart

Change permission for samba share:

# chmod -R 0777 /home/samba/share

Access the samba share from windows (where ip address of my samba server):

Access to Samba share
Access to Samba share
Successfully access to Samba share
Successfully access to Samba share

Add and manage Samba users and groups

Add a group in your CentOS server:

# useradd smbuser
# groupadd smbgrp
# usermod -a -G smbgrp smbuser
# smbpasswd -a smbuser

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

# cd /home/samba/
# mkdir secure
# chown -R smbuser:smbgrp secure/
# chmod -R 0770 secure/

Edit the smb.conf file:

# vi /etc/samba/smb.conf

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

path = /home/samba/secure
valid users = @smbgrp
guest ok = no
writable = yes
browsable = yes
Create new samba share
Create new samba share

Restart the samba service:

# service smb restart
# service nmb restart

Check the syntax error with testparm:

# testparm

Testing from Windows Machine:

Test samba sharing
Test samba sharing

  2. Hi Rasho, great post.

    I’m a Linux novice, and I have created a share called Ativos, its path is /var/www/html. My environment is a Windows Server 2012 Standard domain. Using the command wbinfo I am able to get all users/groups of Windows domain, but when I try to access the created share through a Windows desktop, it returns me access denied.

    In Webmin, I put a Windows valid group in the valid gropus and read/write groups fields, but still cannot access this share.

    Where should I doing it wrong?

    Thanks in advance.
