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)
|
|
is strongly preferred over using older dialects like CIFS due to
|
|
security reaasons. 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 all modern versions of Windows (including Windows 2016
|
|
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 in the future 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.
