In computer networking, Server Message Block SMB, one version of which was also known as Common Internet File System CIFS, ,12 operates as an application layer network protocol3 mainly used for providing shared access to files, printers, and serial ports and miscellaneous communications between nodes on a network. It also provides an authenticated inter process communication mechanism. Most usage of SMB involves computers running Microsoft Windows, where it was known as Microsoft Windows Network before the subsequent introduction of Active Directory. Vray Crack Torrent. Corresponding Windows services are LAN Manager Server for the server component and LAN Manager Workstation for the client component. FeatureseditSMB can run on top of the session and lower network layers in several ways The SMB Inter Process Communication IPC system provides named pipes and was one of the first inter process mechanisms commonly available to programmers that provides a means for services to inherit the authentication carried out when a clientclarification needed first connects to an SMB server. Some services that operate over named pipes, such as those which use Microsofts own implementation of DCERPC over SMB, known as MSRPC over SMB, also allow MSRPC client programs to perform authentication, which overrides the authorization provided by the SMB server, but only in the context of the MSRPC client program that successfully makes the additional authentication. SMB signing Windows NT 4. Service Pack 3 and upwards have the capability to use cryptography to digitally sign SMB connections. The most common official term is SMB signing. Other terms that have been used officially are SMB Security Signatures, SMB sequence numbers7 and SMB Message Signing. SMB signing may be configured individually for incoming SMB connections handled by the Lan. Man. Server service and outgoing SMB connections handled by the Lan. Man. Workstation service. The default setting from Windows 9. And to fall back to unsigned SMB if both partners allow this. The default setting for Windows domain controllers from Windows Server 2. The feature can also be turned on for any server running Windows NT 4. Service Pack 3 or later. This protects from man in the middle attacks against the Clients retrieving their policies from domain controllers at login. The design of Server Message Block version 2 SMB2 aimscitation needed to mitigate this performance limitation by coalescing SMB signals into single packets. SMB supports opportunistic lockinga special type of locking mechanismon files in order to improve performance. SMB serves as the basis for Microsofts Distributed File System implementation. HistoryeditSMB CIFS SMB1editBarry Feigenbaum originally designed SMB at IBM with the aim of turning DOSInterrupt 3. Microsoft has made considerable modifications to the most commonly used version. Microsoft merged the SMB protocol with the LAN Manager product which it had started developing for OS2 with 3. Com around 1. 99. Windows for Workgroups c. Windows. SMB was originally designed to run on top of the Net. BIOSNet. BEUI API typically implemented with NBF, Net. BIOS over IPXSPX, or NBT. Since Windows 2. 00. SMB runs, by default, with a thin layer, similar to the Session Message packet of NBTs Session Service, on top of TCP, using TCP port 4. TCP port 1. 39a feature known as direct host SMB. Windows Server 2. NAS devices use SMB1CIFS natively. SMB1CIFS is an extremely chatty protocol, in that it makes inefficient use of networking resources, particularly when transported over expensive WAN links. While Microsoft estimates that SMB1CIFS comprises less than 1. Enterprise network, that is still a significant amount of traffic. One approach to mitigating the inefficiencies in the protocol is to use WAN Acceleration products such as those provided by Riverbed, Silver Peak, or Cisco Systems. A better approach is simply to eliminate SMB1CIFS by upgrading the server infrastructure that uses it. This includes both NAS devices as well as Windows Server 2. The most effective method in use currently to identify SMB1CIFS traffic is to use a network analyzer tool such as Wireshark, etc., to identify SMB1CIFS talkers and then decommission or upgrade them over time. Microsoft also provides an auditing tool in Microsoft Server 2. SMB1CIFS talkers. In 1. 99. 6 when Sun Microsystems announced Web. NFS,1. 3 Microsoft launched an initiative to rename SMB to Common Internet File System CIFS,1. TCP port 4. 45 without requiring Net. BIOS as a transport a largely experimental effort that required further refinement. Microsoft submitted some partial specifications as Internet Drafts to the IETF,1. SMB 2. 0editMicrosoft introduced a new version of the protocol SMB 2. SMB2 with Windows Vista in 2. Although the protocol is proprietary, its specification has been published to allow other systems to interoperate with Microsoft operating systems that use the new protocol. SMB2 reduces the chattiness of the SMB 1. It has mechanisms for pipelining, that is, sending additional requests before the response to a previous request arrives, thereby improving performance over high latency links. It adds the ability to compound multiple actions into a single request, which significantly reduces the number of round trips the client needs to make to the server, improving performance as a result. SMB1 also has a compounding mechanismknown as And. Xto compound multiple actions, but Microsoft clients rarely use And. X. citation needed It also introduces the notion of durable file handles these allow a connection to an SMB server to survive brief network outages, as are typical in a wireless network, without having to incur the overhead of re negotiating a new session. SMB2 includes support for symbolic links. Other improvements include caching of file properties, improved message signing with HMACSHA 2. The SMB1 protocol uses 1. K. SMB2 uses 3. 2 or 6. Windows VistaServer 2. SMB2 when communicating with other machines also capable of using SMB2. SMB1 continues in use for connections with older versions of Windows, as well various vendors NAS solutions. Samba 3. 5 also includes experimental support for SMB2. Samba 3. 6 fully supports SMB2, except the modification of user quotas using the Windows quota management tools. When SMB2 was introduced it brought a number of benefits over SMB1 for third party implementers of SMB protocols. SMB1, originally designed by IBM, was reverse engineered, and later became part of a wide variety of non Windows operating systems such as Xenix, OS2 and VMS Pathworks. XOpen standardized it partially it also had draft IETF standards which lapsed. See http ubiqx. Intro. SMB2 is also a relatively clean break with the past. Microsofts SMB1 code has to work with a large variety of SMB clients and servers. SMB1 features many versions of information for commands selecting what structure to return for a particular request because features such as Unicode support were retro fitted at a later date. SMB2 involves significantly reduced compatibility testing for implementers of the protocol. SMB2 code has considerably less complexity since far less variability exists for example, non Unicode code paths become redundant as SMB2 requires Unicode support. Apple is also migrating to SMB2 from their own Apple Filing Protocol, now legacy with OS X 1. This transition was fraught with compatibility problems though. Non default support for SMB2 appeared in fact in OS X 1. Apple abandoned Samba in favor of its own SMB implementation called SMBX. Apple switched to its own SMBX implementation after Samba adopted GPLv. The Linux kernels CIFS client file system has SMB2 support since version 3. SMB 2. 1editSMB 2. Windows 7 and Server 2.
