Samba Team Releases Samba 2.0
World's Fastest Windows Server Software
Canberra, Australia, January 1999. The Samba Team is pleased to announce Samba 2.0, a major new release of the award winning Open Source UNIX® file and print server suite for Microsoft Windows ® clients.
World's Fastest Windows File Server
Samba 2.0 has been benchmarked using the Ziff-Davis NetBench ® benchmarking suite as the world's fastest Windows server, achieving 193 megabits per second file serving performance on a Silicon Graphics Origin 200 ® server with 60 Windows clients.
Integration into Windows NT Domains
Samba 2.0 features the first non-Microsoft implementation of the Windows NT Domain authentication protocols, allowing a Samba 2.0 server to be seamlessly integrated into an existing Windows NT Domain. Samba 2.0 is free from client license fees and is the perfect way to add additional high performance Windows file servers using existing UNIX or low cost Linux® machines.
New Easy to use Administration
Samba 2.0 features the Samba Web Administration Tool (SWAT) allowing a Samba 2.0 server to be easily administered via any Web browser from any client. SWAT features an integrated help system and the ability to change user passwords on any Samba or Microsoft Windows NT ® server.
Award Winning UNIX and Windows Integration
Samba won the Windows NT Systems Magazine 1998 "Exceptional Products in Systems Management" award for Unix Connectivity Tools. In the January 1999 awards issue Samba received the following praise :
"Samba is solid, well documented, and feature rich. It is proof that commercial quality software can be had for free."
The Leading Choice for Windows Connectivity
Samba has been adopted by Silicon Graphics ® as a supported product, Samba for IRIX. Silicon Graphics said of Samba :
"Samba for IRIX provides the best combination of features, performance, and data integrity among the available software solutions for serving files via the SMB/CIFS protocol from UNIX."
Samba is also the leading choice of "Thin Server" vendors, who integrate Samba in their products to provide file service to Windows desktops. Samba is used by leading vendors such as Cobalt Networks Inc. in their Cobalt Qube ® microserver, Whistle Communications ® in their Whistle InterJet ® Internet connectivity solution, Corel Computer Corp. ® in their NetWinder ® GS server, and by Realm Information Technologies ® in their REALM ® Universal Server product. Realm Information Technologies said of Samba :
"REALM chose SAMBA for numerous reasons: it was Open Source, very well supported, easily available and cost effective. Little did we know that we were getting incredible performance and stability. Our choice of SAMBA provides our customers with file services that are some of the fastest available on the market today."
Open Source Robustness and Flexibility
As an Open Source product, Samba 2.0 comes with the complete source code to all components of the software. This leads to the legendary Open Source software stability and complete customer flexibility demanded in today's high availability file serving environments. In addition, Samba 2.0 is commercially supported by a worldwide list of corporations and consultants, competing to provide the customer with world class customer support. A listing of support options is available at http://www.samba.org/
Year 2000 Compliant
Samba 2.0 is fully Y2K compliant.
Customer Testimonials
Here's what some of our customers have to say about Samba.
Daniel Petzen of Ericsson Microwave Systems (a wholly owned subsidiary of Ericsson) writes :
We've been running Samba for about a year and a half. We have approximately 700 simultaneous users on 5 UNIX servers serving different NT domains. On our main domain Samba-server we have approximately 500 users and more than 900 connections during the main part of working hours. The server (a Sun E450) is humming along with an average workload of 0.15. None of the servers have ever crashed or failed to function properly due to Samba. Needless to say: We're quite, quite impressed over here. Thank you for a wonderful program.
Dr. Curtis J. Hoff, President, Hoff and Associates, Inc., says :
"Samba is the critical component enabling Hoff and Associates to successfully migrate from an all Unix environment to a mixed NT workstation / Unix compute server environment. Ease of use, performance, robustness and, of course, cost are some of Samba's many strengths."
David Wolf, President, Computer Planet, says :
"As RedHat's only Hardware Partner in Canada, we rely on Samba to provide us with stable, secure, fast and error free communications between our exclusive line of Linux servers and our customer's legacy Windows systems. Samba is perhaps the finest product we have encountered in a long, long time. It does what it says it does--in fact, it works better and faster than the native Windows NT file sharing capabilities!"
Chris Peck, Computer Systems Engineer and Tripp Parks, Student Network Student Engineer, College of William & Mary, Williamsburg, VA say :
"The College of William and Mary began testing Samba in the Spring of 1998. Our test worked out so well that we decided to implement it throughout the campus in time for the Fall semester of 1998. The combination of Unix and Samba has more than met our goals of providing an extremely flexible and robust environment. We are currently using Samba to serve 10755 users on 2800 client machines."

-----------------------------------------------------------
Issues fixed between Beta5 and 2.0.0
------------------------------------
1). Fixed problems with SIGCLD causing infinite looping of
smbd on Solaris in password changing code.
2). Fixed compile problem with mmap for HPUX.
3). Fixed issues with setreuid code not being used in preference
to seteuid code.
4). Added capability to return the same NT ACL that NT does
when queried on a DOS FAT filesystem. This fixes the "not
implemented" error message for GetSecurityDescriptor() calls
that was causing some NT apps to fail.
5). Fixed nmbd strange name loop problem.
6). Added fix to show full pathname for locked files.
7). Re-added FTRUNCATE_NEEDS_ROOT code and autoconf test for
older systems.
8). nmbd now reloads smb.conf in main loop rather than in
signal handler.
9). Re-wrote changenotify tests to do directory scan. Needed
for Visual C++ to work correctly.
10). Re-wrote directory handle code to eliminate handle leak
and allow infinite (well 4096) simultaneous handles using
bitmap code.
11). Fixed bug where MS-Office wouldn't report file in use.
12). Caused timeout processing to be done correctly on timestamps,
not on bogus counter.
13). Cause timeout processing to be done on receipt of SMBecho.
14). Added code to cope with NT bug where it's sending 64 bit
lock ranges to a server that only handles 32 bit ranges.
15). Allows %S substitution to be used in force user.
16). Fixed autoconf test for setreuid.
17). Fixed bug in testparm with password changing parameter.
18). Fixed SWAT bug - now remove 'commit' button from areas where
user doesn't have write access.
-----------------------------------------------------------
Issues fixed between Beta4 and Beta5
------------------------------------
1). Recuse directory bug with NT and smbtar fixed. smbtar now
recurses through all directories correctly.
2). Subtle bug fixed with the SIGCLD eating process status values
in cases where they are needed.
3). Fixed autoconf detection and handling of the different
setresuid/seteuid/setuid calls on different UNIXs.
4). Wrapped readdir64 for large file support.
5). Fixed --with-nisplus compile for Solaris.
6). Fixed wildcard bug with 16 bit clients. Also got closer
to NT wildcard semantics.
7). Allowed seek fails with EPIPE when doing client seeks to
allow Windows clients to communicate with UNIX processes via
fifo's (worked on 1.9.18, was broken in 2.0.0beta1-4).
8). Fixed compile bug with slow share mode code.
9). Fixes for QNX compiles.
10). Fixed recursion bug in nmbd if WINS server returns an
error at a bad time :-).
11). Log AFS auth fail.
12). Fixed Digital UNIX enhanced security problem with SWAT.
13). Updated SID generation code to produce NT compatible SIDs.
14). Fixed bug with ENOSPC on close() calls. This should now
be detected and returned to the client.
15). NT transact parameters weren't being zeroed out before use.
16). Fixed lockread bug where it was asking for a read-only
lock. It should be using a write lock (however strange this
seems :-).
17). Many SWAT printer fixes from Herb Lewis.
18). SWAT parameters now grouped in a more logical way.
19). Changed main smbd select loop to 60 seconds, smb.conf checks
to every 120 seconds to reduce load on large servers.
-----------------------------------------------------------
Issues fixed between Beta3 and Beta4
------------------------------------
1). More sanity checks in testparm code to help diagnose smb.conf
problems.
2). Ensure log header not written before log rotated.
3). Fix getrlimit number of file descriptors problem with AIX.
AIX supports the call but always returns infinity. This was
causing smbd to try and allocate a large amount of memory.
4). Fixed name lookup in lmhosts to match the documentation for
name type lookup.
5). Removed need to link password database code into nmbd.
6). Stop nmbd sending broadcast name refresh requests, use
permanent TTL on broadcast interfaces.
7). Flag "PRINTER" and "SHARE" parameters so SWAT can display
them correctly.
8). Fix SWAT so that it can display auto-generated printer list.
9). Added AFS and DCE auth includes back.
10). Added workaround to Windows NT redirector bug where it sends
64 bit lock requests to systems that don't support 64 bit offsets
(eg. Linux).
11). Fixed name mangling cache bug.
12). Fix smbpasswd bug where a missmatched password could be mis-interpreted
when adding a user.
13). Updates to SWAT to display "commit" button if user has write
access to smb.conf.
14). Fixed to autoconf for HPUX systems to work around broken
HPUX shadow.h include file.
-----------------------------------------------------------
Issues fixed between Beta2 and Beta3
------------------------------------
1). New parameters added :
"add user script"
"delete user script"
Designed to allow Samba servers to be set up with
no UNIX users and to allow them to create the needed
UNIX users on the fly. See the smb.conf documentation
for more details.
2). Autoconf issues including fixes for large file support for
Solaris and SINIX, and stat64 tests on SVR4 systems.
3). Code dealing with dos pathnames and native pathnames split
to be explicit about when Samba is accessing which type of
name.
4). Fix for missing PRINTCAP define under HPUX.
5). Added Samba specific strtoul().
6). Fix for reverse filename mapping with ISO8859-5 filenames.
7). Fix for nmbd not starting correctly sometimes due to pid
locking file.
8). Check for error returns in file descriptor limit checking code.
9). Kernel oplock code bugfix.
10). Restored client retarget code.
11). Fix for potential stack overflow in Digital UNIX crypt check.
12). Explicitly test for negative uids in smbpasswd file.
13). Fix for NT username in Domain logon code.
14). Patch from Scott Moomaw scott@bridgewater.edu to correctly
return "Invalid Info level" to Win95 printer clients.
15). Fix to allow NT printer clients to add printers (as 1.9.18
code would allow).
16). Fix to prevent ".." being used in servicename.
17). New SWAT icons.

-----------------------------------------------------------
WHATS NEW IN Samba 2.0.0
========================
This is a MAJOR new release of Samba, the UNIX based SMB/CIFS file
and print server for Windows systems.
There have been many changes in Samba since the last major release,
1.9.18. These have mainly been in the areas of performance and
SMB protocol correctness. In addition, a Web based GUI interface
for configuring Samba has been added.
In addition, Samba has been re-written to help portability to
other POSIX-based systems, based on the GNU autoconf tool.
Major changes in Samba 2.0
--------------------------
There are many major changes in Samba for version 2.0. Here are
some of them:
=====================================================================
1). Speed
---------
Samba has been benchmarked on high-end UNIX hardware as out-performing
all other SMB/CIFS servers using the Ziff-Davis NetBench benchmark.
Many changes to the code to optimise high-end performance have been made.
2). Correctness
---------------
Samba now supports the Windows NT specific SMB requests. This
means that on platforms that are capable Samba now presents a
64 bit view of the filesystem to Windows NT clients and is
capable of handling very large files.
3). Portability
---------------
Samba is now self-configuring using GNU autoconf, removing
the need for people installing Samba to have to hand configure
Makefiles, as was needed in previous versions.
You now configure Samba by running "./configure" then "make". See
docs/textdocs/UNIX_INSTALL.txt for details.
4). Web based GUI configuration
-------------------------------
Samba now comes with SWAT, a web based GUI config system. See
the swat man page for details on how to set it up.
5). Cross protocol data integrity
---------------------------------
An open function interface has been defined to allow
"opportunistic locks" (oplocks for short) granted by Samba
to be seen by other UNIX processes. This allows complete
cross protocol (NFS and SMB) data integrety using Samba
with platforms that support this feature.
6). Domain client capability
----------------------------
Samba is now capable of using a Windows NT PDC for user
authentication in exactly the same way that a Windows NT
workstation does, i.e. it can be a member of a Domain. See
docs/textdocs/DOMAIN_MEMBER.txt for details.
7). Documentation Updates
-------------------------
All the reference parts of the Samba documentation (the
manual pages) have been updated and converted to a document
format that allows automatic generation of HTML, SGML, and
text formats. These documents now ship as standard in HTML
and manpage format.
=====================================================================
NOTE - Some important option defaults changed
---------------------------------------------
Several parameters have changed their default values. The most
important of these is that the default security mode is now user
level security rather than share level security.
This (incompatible) change was made to ease new Samba installs
as user level security is easier to use for Windows 95/98 and
Windows NT clients.
********IMPORTANT NOTE****************
If you have no "security=" line in the [global] section of
your current smb.conf and you update to Samba 2.0 you will
need to add the line :
security=share
to get exactly the same behaviour with Samba 2.0 as you
did with previous versions of Samba.
********END IMPORTANT NOTE*************
In addition, Samba now defaults to case sensitivity options that
match a Windows NT server precisely, that is, case insensitive
but case preserving.
The default format of the smbpasswd file has also been
changed for this release, although the new tools will read
and write the old format, for backwards compatibility.
=====================================================================
NOTE - Primary Domain Controller Functionality
----------------------------------------------
This version of Samba contains code that correctly implements
the undocumented Primary Domain Controller authentication
protocols. However, there is much more to being a Primary
Domain Controller than serving Windows NT logon requests.
A useful version of a Primary Domain Controller contains
many remote procedure calls to do things like enumerate users,
groups, and security information, only some of which Samba currently
implements. In addition, there are outstanding (known) bugs with
using Samba as a PDC in this release that the Samba Team are actively
working on. For this reason we have chosen not to advertise and
actively support Primary Domain Controller functionality with this
release.
This work is being done in the CVS (developer) versions of Samba,
development of which continues at a fast pace. If you are
interested in participating in or helping with this development
please join the Samba-NTDOM mailing list. Details on joining
are available at :
http://lists.samba.org/listinfo/samba-ntdom/
Details on obtaining CVS (developer) versions of Samba
are available at:

If you have problems, or think you have found a bug please email
a report to :
samba-bugs@samba.org
As always, all bugs are our responsibility.
