LIS 525 - Samba
What Is Samba?
Samba is a suite of programs
that allows Windows clients to access
a Unix/Linux server's filespace and printers.
This means, for example,
that you can connect to UNIX/Linux disks and printers
from Windows clients.
Samba uses the SMB and CIFS protocols.
SMB (Server Message Block) is a client server, request-response
for sharing files, printers, serial ports, and communications
(such as pipes) between computers.
All Windows (95 or better) machines are capable of running SMB.
CIFS (Common Internet File System)
is a specification based on SMB
for a file access protocol for the Internet.
The two key programs in Samba
are smbd (SMB Daemon)
which implement the four basic CIFS services:
Name resolution and browsing basically involve
management and distribution of lists of NetBIOS names.
For name resolution,
a machine may broadcast a call for a service with a given
and wait for that machine to answer with an IP address
or it may use an NBNS (NetBIOS Name Service)
(called WINS, Windows Internet Name Service, in Windows) server,
where machines can have left their name and IP address.
Browsing refers to a browsable list of services (file and print
offered by the computers on a network.
One machine on a LAN is designated as LMB (Local Master
whose job is to keep a list of available services.
- file & print services (smbd);
- authentication and authorization
(requiring passwords, smbd);
- name resolution (nmbd);
- browsing (nmbd).
One of the utilities that is included in Samba is
which can be used to find NetBIOS names on a network,
look up their IP addresses,
and query a remote machine for its list of names.
Accessing a Samba Server
a common way of accessing a samba server is through drive mapping.
This mapping should occur automatically for the UWO Samba server
when MLIS students log in to the FIMS LAN.
Otherwise the following method can be used.
Select "Map Drive"
in Control Panel or Windows Explorer;
type \\ + the server name + \ + your user name
in the "Path" box
and click on "OK";
if this is your first access to the Unix area
in this session,
enter your password and click on "OK".
You can drop this kind of connection
by selecting "Disconnect"
in Control Panel or Windows Explorer,
selecting the virtual drive from the list,
and clicking on "OK".
There are at least two conditions
to making this kind of access work.
- Your user name
(though not your password)
should be the same on both the Windows machine
and the Unix/Linux machine
(this is the normal FIMS setup,
but user names might be different
if you are trying to access a Samba server elsewhere).
- For older Samba servers
Windows 98 needs to be set to allow unencrypted passwords.
One way to do this is to run Regedit.exe
and change the EnablePlainTextPassword
value under "VNSETUP" to 1;
but note that there is a potential security risk.
Unix/Linux and DOS/Windows plain text files differ very slightly.
The Unix/Linux convention is to end each line
with just a line feed character
in DOS/Windows each line ends with
a carriage return plus line feed sequence
(ASCII #13 plus ASCII #10).
Some Windows programs,
such as PFE,
will recognize which kind of file they are dealing with,
and PFE will even allow you to choose
which convention to follow.
Other Windows programs, however,
such as Notepad,
read Unix/Linux files more literally.
This means that,
if you open a plain text file created in Unix/Linux
in Windows using Notepad,
all the lines will appear jammed together
as a single line
(or paragraph, if Word Wrap is on),
sometimes with little black squares between them.
