Samba and IP Forwarding

Samba can be used to share file and printer between linux to linux, linux to Unix and Linux to windows.

Service Profile

Type            :        System V Manage
Package       :        Samba, samba-common, samba-client
Daemon       :       smbd, nmbd
Script           :        smb
Port             :        167,168,169
Configuration file    :        /etc/samba/smb.conf
                                             /etc/samba/smbpasswd

Edit the file smb.conf

#vi /etc/samba/smb.conf

Workgroup = CORP

Server String = Samba

Host allow = 172.24.254.254/255.255.0.0

Then copy last 8 line

[jeet]

Path = /data

Valid users = jeet Deepak

Public = no

Writeable = yes

Browse able = yes

Save and exit

Now create a Users

#adduser jeet

#adduser Deepak

#smbpasswd –a jeet

#smbpasswd –a Deepak

Start the service

#service smb restart

#chkconfig smb on

On client side

#smbclient //172.24.254.254/jeet –U jeet

GUI

Smb://172.24.254.254

Mounting share folder

#smbmount //172.24.254.254/data /mnt –o username=Deepak

 IP Forwarding:-

In Linux, we can’t use a computer with two network interface to route between two or more subnet. To be able to do this we need to make sure that we enable IP forwarding. We should make sure that module is loaded. To check type

#cat /proc/sys/net/ipv4/ip-forward

If forwarding is enabled, the number 1 is returned. If forwarding is not enabled, the number 0 is returned.

To enable IP forwarding

#vi /etc/sysctl.conf

Line no.7

Net.ipv4.ip_forward = 1

Save and exit

To activate permanently

 #sysctl –p

Or another method is

#echo 1 >/proc/sys/net/ip_forward

This work for temporary use till system is ‘ON’

Now for the first network

#netconfig

            IP address                   :          172.24.254.254

            Subnet                         :           255.255.0.0

            Default Gateway         :           172.25.254.254

            Primary server            :           172.24.254.254

Second network

#netconfig –d eth0:1                          (-d : virtual)

IP Address                    :         172.25.254.254

Subnet                           :         255.255.0.0

Default Gateway           :         172.24.254.254

            Primary Server             :         172.24.254.254
