What is Samba ??
Samba is an Open Source Suite, that provides seamless file and print services to SMB/CIFS clients.
With Samba, you can share a Linux file system
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
Samba is essentially a TCP/IP file and print
server for Microsoft Windows clients
It can support any SMB/CIFS-enabled client
SMB/CIFS?
SMB is Server (or Session) Message Block
Common Internet File System (CIFS) is
Windows File Sharing
(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 NT, OS/2, and Linux
SMB was originally developed to run over
NetBIOS (Network Basic Input Output System) LANs in the mid-1980
SMB was originally for MS-DOS and PC-DOS
Operates as an application-level network protocol
Applied to shared access to Files,
printers, serial ports, and miscellaneous communications between nodes on a
network
Provides an authenticated Inter-process
communication mechanism
Most usage of SMB involves computers
running Microsoft Windows
Microsoft environments users often know it
simply as "Microsoft Windows Network“
When discussing SMB, one should distinguish:
SMB the protocol
SMB services that run on the protocol
NetBIOS
DCE/RPC services that use SMB as an
authenticated Inter-process communication channel (over named pipes)
"Network Neighborhood" protocols
which primarily (but not exclusively) run as datagram services directly on the
NetBIOS transport
Common
Internet File System (CIFS)
CIFS is a network file system plus a set of
auxiliary services supported by a bunch of underlying protocols
Most of which are not particularly well documented
by Microsoft.
CIFS is "Microsoft's way of doing
network file sharing“since about 1996
There is no RFC number for SMB or CIFS
Microsoft's implementations are the de
facto CIFS standards
Network
File Sharing
SAMBA is an SMB/CIFS file sharing daemon
that runs on UNIX hosts.
Clients make SMB requests on the network
Samba accepts SMB file requests from
clients and uses UNIX calls to obtain requested file from disks.
Samba returns SMB file information to the
client.
SAMBA is free.
TotalNet is another solution which performs
the same function.
TotalNet is a commercial product.
Dave” performs the same function for MacOS.
(Free)
Xinet is a commercial product that performs
the same function.
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
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
[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.
Sharing
files and print services:
Example of directory or file share:
[jacksdir]
comment
= remote source code directory
path
= usr/local/src
valid
users = abc
browseable
= yes
public
= no
writeable
= yes
Example of printer sharing:
[vals_lp]
print
ok =yes
printer
name = lp_mine
path
= /home/everyone
valid
users = user@server.co
browseable
= yes
Available
permissions
The following Access Control List permissions
can be granted:
Lookup (l)
allows a user to list the contents of the
AFS directory, examine the ACL associated with the directory and access
subdirectories.
Insert (i)
allows a user to add new files or
subdirectories to the directory.
Delete (d)
allows a user to remove files and
subdirectories from the directory.
Administer (a)
allows a user to change the ACL for the
directory. Users always have this right on their home directory, even if they
accidentally remove themselves from the ACL.
Permissions that affect files and
subdirectories include:
Read (r)
allows a user to look at the contents of
files in a directory and list files in subdirectories. Files that are to be
granted read access to any user, including the owner, need to have the standard
UNIX "owner read" permission set.
Write (w)
allows a user to modify files in a
directory. Files that are to be granted write access to any user, including the
owner, need to have the standard UNIX "owner write" permission set.
Lock (k)
allows the processor to run programs that
need to "flock" files in the directory. See the UNIX man page for
"flock" for more details.
