How does CIFS work? CIFS uses the client-server model to share files across distinct network systems: A client sends a request to a server. Each packet usually contains a simple request. After that, the client parses the response packet to see if the original request was accurate.

Microsoft operating systems are the most frequent users of the CIFS protocol. Remote disc operations, searching, authentication, and remote printer services all use Common Internet File System in Microsoft operating systems.

Ajay Sarangam 17 Mar A single client can connect to multiple servers and, if needed, can connect to the same server multiple times. Client Access to Services: The protocol does not restrict the types of resources to which clients can bind. CIFS clients will bind to shared directories, called streams, print queues, and other services simultaneously. Context of Security: The protocol does not impose a particular security context on the client.

If required, multiple protection contexts may be used over a single connection. Furthermore, file sharing is a server operating system feature, and CIFS does not enforce file locks. This ensures that a file can be accessed by several clients at the same time. Interprocess Communication through Named Pipes: Common Internet File System permits the use of named pipes as a communication channel between the client and the server.

Although its main purpose is file sharing, additional Microsoft SMB Protocol functionality includes the following: Dialect negotiation Determining other Microsoft SMB Protocol servers on the network, or network browsing Printing over a network File, directory, and share access authentication File and record locking File and directory change notification Extended file attribute handling Unicode support Opportunistic locks In the OSI networking model, Microsoft SMB Protocol is most often used as an Application layer or a Presentation layer protocol, and it relies on lower-level protocols for transport.

These packets can be broadly classified as follows: Session control packets Establishes and discontinues a connection to shared server resources. File access packets Accesses and manipulates files and directories on the remote server.

General message packets Sends data to print queues, mailslots, and named pipes, and provides data about the status of print queues.
