File sharing in Linux

SAMBA SERVER SETUP

2. Samba Server Setup
Samba Service
File and Printer Sharing from LINIX to Windows
Uses smb Daemon
service smb start/stop/restart

3. Samba Server Setup
What is Samba??
Samba is an Open Source Suite, that provides seamless file and
print services to SMB/CIFS clients.
• Samba is freely available.
• With Samba, you can share a Linux files ystem with
Windows and vice versa.
• You can also share printers connected to either Linux or a
system with Windows.
• Samba enables a Linux or Unix server to function as a file
server for client PCs running Windows software.

4. Samba Server Setup
What is Samba??
What is SMB?
• SMB stands for – Server Message Block.
• It is a protocol by which a lot of PC-related machines
share files and printers and other information such as
lists of available files and printers.
• Operating systems that support this natively include
Windows, OS/2, and Linux.
What is CIFS?
• CIFS – Common Internet File System is a protocol
that is basically an updated SMB.

5. Samba Server Setup
Components of SMB
smbd daemon: This provides the file and print services to SMB
clients such as Windows NT or other Linux or Unix clients.
• smb.conf: This is the configuration file for smbd.
• nmbd daemon: This daemon provides NetBIOS
nameserving and browsing support.
• smbclient: This is an smb client program that implement a
simple FTP-like client on a Linux or Unix box.
• smbmount: This mounting program enables mounting of
server directories on a Linux or Unix box.

6. Samba Server Setup
Components of SMB
• testparm: This utility is used to test the smb.conf
configuration file.
• smbstatus: This programs lists the current Samba
connections.
• SWAT: Swat allows a Samba administrator to configure the
smb.conf file via a Web browser.
• smbpasswd: This allows the user to change the password
used for their SMB sessions.

7. Samba Server Setup
Installation and Setup
The Samba Server package can be downloaded from the
Samba website.
• The file needs to be untared and then configured using
a ./configure command in the source directory.
• Then the smb.conf file should be created. The smb.conf file
has three separate sections:
[global] : This section controls parameters for the entire SMB
server. It also provides default values for the other sections.
Examples: workgroup = MYGROUP
server string = Samba Server

8. Samba Server Setup
Installation and Setup
Continued…
hosts allow = 192.168.1 127.
printcap name = /etc/printcap
load printers = yes
guest account = pcguest
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
[homes]: This section allows network clients to connect to a
user’s home directory without having an explicit entry in the
smb.conf file.
Examples:
[homes]
browseable = no
writeable = yes

9. Samba Server Setup
Installation and Setup
Continued…
[printers]: This section is used to specify which printers
are available.
Examples:
[printers]
print ok = yes
printer name = lp_mine
path = /home/everyone
The testparm program helps in testing the smb.conf
file once it is configured.

10. Samba Server Setup
Samba Server Configuration
Use GUI Applications  Server Settings  Services  SMB
Configuration File: /etc/samba/smb.conf
Configuring File and Directory Sharing
[share_name]
comment = Fred's Home Directory
path = /home/fred
valid users = fred
public = no
writable = yes
printable = no

11. Samba Server Setup
Samba Server Configuration
Configuring Printer Sharing
[printer_share_name]
comment = Fred's Printer
valid users = fred
path = /var/spool/samba
printer = freds_printer
public = no
writable = no
printable = yes

12. Samba Server Setup
Authentication Methods
Use local username/password (stored in
/etc/samba/smbpasswd)
To add a local user: smbpasswd –a fred (fred should be a
user in /etc/passwd)

13. HOW TO CONNECT LINUX TO WINDOW
Step 1st. First we check there is samba server package is installed or not. We find package
samba* not installed. Then we install samba* package with help of yum server.
Here samba server is installing

14. Here samba* installation is completed.

15. Step 2nd. We have to create a DIRECTORY on / which one has to be shared. Then we create
a valid user who has been shared the directories.
1.4
Directory (/manoz) and valid (AARAV) user has been created.

16. Step 3rd. Now we get the knowledge of our system’s IP address and who has been made by us is being connecting or not.
1.5
Now we got system’s IP address. But there is error in connection. Now we have to
troubleshoot this connection error for this valid user.

17. Step 4th. In the next step we open the samba server configuration file.
Command: vim /etc/samba/conf/smb.conf
1.6
This is configuration file.

18. 1.7
This is also a part of configuration file.

19. Step 5th. Last page of configuration file we make some changes here.
1.8
After saving changes safely we came out from this configuration file.

20. Step 6th. Now we check the context of directory (/manoz).
Command: ls –lZ /manoz
1.9
Context of the directory is default now we make it samba because directory is shared by particular Samba server.

21. Step 7th. For changing the context of the directory we have to set boolians of the samba server.
1.10
Using getsebool command we can turn on the Booleans of samba.

22. Step 8th. Now we set context of directory as samba.
Command: chcon –R –t samba_etc_t /manoz
1.11
Context changed of directory successfully.

23. Step 9th. Now we try to connect the user.
Command: smbclient //192.168.0.12/manoz –U AARAV
1.12
Connection is successfully done.

24. Step 10th. Check the shared directory.
Command: ls
1.13
Shared directory is there.

25. Samba Server Setup
Samba Client Configuration
Share the Samba Directory on Windows machine
Share the Samba Filesystem on Unix machine by
specifying in /etc/fstab
server1:/smbdata /users/smbdata smbfs defaults 0 0
or use
smbmount //server1/smbdata /users/smbdata –o
username=fred

26. Samba Server Setup
Samba Basic Configuration
# mkdir santosh
# cd santosh
# ls
# touch a b c d (touch – blank file creation)
# ls

27. Samba Server Setup
Samba Basic Configuration
# nano /etc/samba/smb.conf
(Go to end of config file i.e from public and remove the comments)
Make following ammendment
[santoshshare] (by replacing [public])
Comment = My share files
Path = /santosh
Public = yes
Browseable = yes
Valid users = santosh
Writable = no
Hosts allow = 192.168.1. (only 3 octets)
(save and exit)

28. Samba Server Setup
Samba Basic Configuration
# smb passwd –a santosh
Passwd : abc123 (any password)
Retype passwd : abc123
# service smb restart
Go to windows – run – and type
– 192.168.1.111(samba server ip)

29. Samba Server Setup
Samba Basic Configuration
(Disable iptables)
# iptables –L (wiil display iptables)
# iptables – F (wiil flush iptables)
# service iptables save
# service iptables stop
# set enforce 0 (enforce policy)
(now go to run in windows and type 192.168.1.111)
