Samba

Disable SELinux

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:

# 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 =====================================

[global]

workgroup = WORKGROUP

security = share

map to guest = bad user

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

[MyShare]

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 192.168.1.15 ip address of my samba server):

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:

[Secure]

path = /home/samba/secure

valid users = @smbgrp

guest ok = no

writable = yes

browsable = yes

Restart the samba service:

# service smb restart

# service nmb restart

Check the syntax error with testparm:

# testparm
