 Server Message Block - Wikipedia, the free encyclopedia
SMB is also used as the basis for Microsoft's Distributed File System implementation.
SMB was originally invented by IBM to turn DOS "Interrupt 33" local file access into a networked file system, but the most common version is modified heavily by Microsoft.

 IBM SMB: Server Message Block protocol
SMB is a client server, request-response protocol, which provides a method for client applications in a computer to read and write to files on and to request services from server programs in various types of network environment.
Server Message Block (SMB) protocol is an IBM protocol for sharing files, printers, serial ports, etc. between computers.

 Server Message Block
SMB was developed by Intel, Microsoft, and IBM in the early 1980s.
There are SMB servers and clients for Unix, for example Samba and smbclient.
Microsoft have developed an extended version of SMB for the Internet, the Common Internet File System (CIFS), which in most cases replaces SMB.

 Security Pipeline Web Sites Running On Windows NT At Risk
SMB is used by Windows to share files, printers, and serial ports, and to communicate between computers, particularly between servers and client desktops.
The bug in a key Windows protocol, Server Message Block (SMB), was patched for Windows XP, Windows Server 2003, and Windows 2000 in February, but because NT 4 had reached the end of its support lifecycle December 31, 2004, no public fix was issued by Microsoft.
More information on how to turn on SMB signing can be found on Microsoft's Web site.

 Server Message Block Protocols
SMB is a combination of NFS, lpd, a security system like Kerberos and a little more.
Like NFS, SMB allows a file system to be shared across a network.
Where NFS is limited to file system sharing, SMB also implements the sharing of printers and other services as well as simple network messaging.

 Server Message Block Protocol
SMB requires a transport /session protocol and the early versions of IBM's implementation were closely linked with NetBIOS.
SMB is very analogous to the NetWare Core Protocol (NCF); there are numerous functions available for accomplishing various tasks.
Despite having released a version of SMB to the X-Open organization, Microsoft continues to develop the protocol as a proprietary protocol and details of some of the more recent versions have not been made freely available.

 Chapter 19: Samba - The Server Message Block Protocol (SMB)
SMB is the protocol by which a lot of PC-related machines share files, printers, and network information such as lists of available files and printers.
You can access file systems located on Windows machines from your Linux boxes and mount file systems exported by a Linux server on your Windows workstation.
Packages that achieve the same result are available for DOS, other versions of Windows, VMS, Unix of all flavors, MVS, and more.

 Server Message Block-Based File Services
Additionally, with NFS, there is less of a burden on the server because much of the NFS processing is performed on the local workstation.
CIFS is based on the Windows NT LM 1.2 revision of the SMB protocol and is being championed by Microsoft and other vendors as an Internet version of SMB.
To test performance, we used Network Computing's FileMetric benchmark utility, which performs both reads and writes to the server using two NT clients (3.51 and 4.0) with a Windows95 workstation as the control workstation.

 The Server Message Block protocol
Under Windows, SMB is referred to as "Microsoft Networking".
You probably need to be running an SMB service if you want to make files and printers available to Windows systems, although there are other protocols they can use.
It is a general maxim of computer security that the fewer network services you run the more secure your system will be.

amba, an open-source implementation of Microsoft's Server Message Block protocol that facilitates file-sharing between Unix or Linux systems and Windows clients and servers, is not immune to interoperability problems with Windows 2000.
"The main reason for using Samba is that it does what we need from a central point--one server on the Unix box--as opposed to buying a Network File System program or license for every PC that needs access to the Unix file system," says Dave Oberholzer, manager of data services for Measurisk.com.
Oberholzer says his IT organization ran Samba with no problems until Microsoft modified its interface for Server Message Block in Windows 2000.
