- ============
- Introduction
- ============
- This is the client VFS module for the SMB3 NAS protocol as well
- as for older dialects such as the Common Internet File System (CIFS)
- protocol which was the successor to the Server Message Block
- (SMB) protocol, the native file sharing mechanism for most early
- PC operating systems. New and improved versions of CIFS are now
- called SMB2 and SMB3. Use of SMB3 (and later, including SMB3.1.1
- the most current dialect) is strongly preferred over using older
- dialects like CIFS due to security reasons. All modern dialects,
- including the most recent, SMB3.1.1, are supported by the CIFS VFS
- module. The SMB3 protocol is implemented and supported by all major
- file servers such as Windows (including Windows 2019 Server), as
- well as by Samba (which provides excellent CIFS/SMB2/SMB3 server
- support and tools for Linux and many other operating systems).
- Apple systems also support SMB3 well, as do most Network Attached
- Storage vendors, so this network filesystem client can mount to a
- wide variety of systems. It also supports mounting to the cloud
- (for example Microsoft Azure), including the necessary security
- features.
- The intent of this module is to provide the most advanced network
- file system function for SMB3 compliant servers, including advanced
- security features, excellent parallelized high performance i/o, better
- POSIX compliance, secure per-user session establishment, encryption,
- high performance safe distributed caching (leases/oplocks), optional packet
- signing, large files, Unicode support and other internationalization
- improvements. Since both Samba server and this filesystem client support the
- CIFS Unix extensions, and the Linux client also supports SMB3 POSIX extensions,
- the combination can provide a reasonable alternative to other network and
- cluster file systems for fileserving in some Linux to Linux environments,
- not just in Linux to Windows (or Linux to Mac) environments.
- This filesystem has a mount utility (mount.cifs) and various user space
- tools (including smbinfo and setcifsacl) that can be obtained from
- https://git.samba.org/?p=cifs-utils.git
- or
- git://git.samba.org/cifs-utils.git
- mount.cifs should be installed in the directory with the other mount helpers.
