The Samba Team is proud to announce the release of Samba 3.2, a
major new release of the award-winning Free Software file and print
server suite for Microsoft Windows clients.
The Evolution of the Samba Platform
Samba 3.2 builds upon the success of Samba 3.0 by modernizing
and enhancing the code whilst still retaining compatibility with
all existing Samba installations. Samba is the leading technology
choice for Windows file serving on UNIX platforms and in embedded
Network Attached Storage (NAS) solutions. Samba is used by vendors
selling NAS solutions ranging from high end clustered
business-critical systems, to low end consumer devices, and
everything in between.
Clustered File Server Support
Samba 3.2, in conjunction with the ctdb libraries and a back-end
distributed file system such as Sun's Lustre, IBM's GPFS or Red
Hat's GFS, can provide a fully clustered file server solution.
Every node is able to simultaneously serve an identical, consistent
view of the exported file system. Not just a simple "fail-over"
high availability solution, Samba 3.2 with ctdb provides a scalable
clustered file server solution with full Windows file sharing
semantics. Samba and ctdb are already being shipped in production
file serving products to some of the most demanding customers in
the world in fields such as animation and video production.
Samba 3.2 introduces a 'registry' based configuration system.
This allows vendors embedding Samba in an appliance to more easily
manage Samba configuration via the supplied commands or library
functions without having to write scripts to modify a text
Improved Integration with Microsoft Windows
Samba 3.2 has been designed and tested to integrate with the
latest Microsoft Windows clients and servers, such as Windows Vista
service pack 1, and Windows server 2008.
Encrypted Network Transport
An innovation created by the Samba Team, Samba 3.2 has extended
the CIFS/SMB protocol to allow transport encryption. File system
shares may now be marked as "encrypted" and all access to these
shares is now encrypted over the network. Standard GSSAPI
encryption techniques are used to safeguard the data. This
extension to the CIFS/SMB protocol is open and available for other
vendors to adopt without requiring patent licenses or other
Reduced Memory Requirements
The memory footprint of Samba has been reduced by the use of the
Samba developed "talloc" library, in order to allow greater use of
Samba in embedded devices with limited memory requirements. All
restrictions on file name lengths have been removed.
The networking functions have been re-written to ensure Samba
3.2 is fully IPv6 compliant. Customers may now use Samba in an
IPv6-only network, and it has been tested to work with Microsoft
Windows (R) IPv6 implementations as well as UNIX (R) IPv6
New Library Code
Samba 3.2 begins the migration of Samba from a monolithic
application to a more modular architecture comprised of library
functions which can be used to control and configure the Samba
environment. The new libnetapi library to control domain membership
is one of the first examples of this new approach.
New Release Manager
Samba 3.2 marks the debut of Karolin Seeger as our new release
manager, funded full time to work on Samba releases by SerNet GmbH. The Samba Team is happy to
welcome Karolin as a Team member, and we hope that Karolin will be
driving our release process for many years to come.
Now Licensed Under the GNU GPLv3
The Samba Team has adopted the Version 3 of the GNU General
Public License for the 3.2 and later releases. The GPLv3 is the
updated version of the GPLv2 license under which Samba is currently
distributed. It has been updated to improve compatibility with
other licenses and to make it easier to adopt internationally, and
is an improved version of the license to better suit the needs of
Free Software in the 21st Century.
