10/3/2023 0 Comments Smb linux![]() ![]() The "Server" service (ID: LanmanServer) is in charge of serving shared resources. In Microsoft Windows, two vaguely named Windows services implement SMB. On NetBT, the server component uses three TCP or UDP ports: 137 (NETBIOS Name Service), 138 (NETBIOS Datagram Service), and 139 (NETBIOS Session Service). SMB originally operated on NetBIOS over IEEE 802.2 - NetBIOS Frames or NBF - and over IPX/SPX, and later on NetBIOS over TCP/IP (NetBT), but Microsoft has since deprecated these protocols. The SMB server component uses TCP port 445. ![]() This combination allows file sharing over complex, interconnected networks, including the public Internet. SMB relies on the TCP and IP protocols for transport. SMB serves as the basis for Microsoft's Distributed File System implementation. Server Message Block (SMB) enables file sharing, printer sharing, network browsing, and inter-process communication (through named pipes) over a computer network. Microsoft has since discontinued use of the CIFS moniker but continues developing SMB and making subsequent specifications publicly available. Microsoft's proposal, however, remained an Internet Draft and never achieved standard status. It supports symbolic links, hard links, and larger file size, but none of the features of SMB 2.0 and later. CIFS was compatible with even the earliest incarnation of SMB, including LAN Manager's. In 1996, Microsoft published a version of SMB 1.0 with minor modifications under the Common Internet File System ( CIFS / s ɪ f s/) moniker. It uses NTLM or Kerberos protocols for user authentication. ![]() SMB implementation consists of two vaguely named Windows services: "Server" (ID: LanmanServer) and "Workstation" (ID: LanmanWorkstation). SMB over QUIC was introduced in Windows Server 2022. Later, Microsoft implemented SMB in Windows NT 3.1 and has been updating it ever since, adapting it to work with newer underlying transports: TCP/IP and NetBT. In 1987, Microsoft and 3Com implemented SMB in LAN Manager for OS/2, at which time SMB used the NetBIOS service atop the NetBIOS Frames protocol as its underlying transport. It also provides an authenticated inter-process communication (IPC) mechanism. Feigenbaum at IBM and intended to provide shared access to files and printers across nodes on a network of systems running IBM's OS/2. Server Message Block ( SMB) is a communication protocol originally developed in 1983 by Barry A. Network communication protocol for providing shared access to resources ![]()
