When SMB2 was introduced it brought a number of benefits over SMB1 for third party implementers of SMB protocols. SMB1, originally designed by IBM, was reverse engineered, and later became part of a wide variety of non-Windows operating systems such as Xenix, OS/2 and VMS (Pathworks). X/Open standardized it partially; Microsoft had submitted Internet-Drafts describing SMB2 to the IETF, partly in response to formal IETF standardization of version 4 of the Network File System in December 2000 as IETF RFC 3010.[30]; however, those SMB-related Internet-Drafts expired without achieving any IETF standards-track approval or any other IETF endorsement. (See for historical detail.) SMB2 is also a relatively clean break with the past. Microsoft's SMB1 code has to work with a large variety of SMB clients and servers. SMB1 features many versions of information for commands (selecting what structure to return for a particular request) because features such as Unicode support were retro-fitted at a later date. SMB2 involves significantly reduced compatibility-testing for implementers of the protocol. SMB2 code has considerably less complexity since far less variability exists (for example, non-Unicode code paths become redundant as SMB2 requires Unicode support).
Apple migrated to SMB2 (from their own Apple Filing Protocol, now legacy) starting with OS X 10.9 "Mavericks".[31] This transition was fraught with compatibility problems though.[32][33] Non-default support for SMB2 appeared in fact in OS X 10.7, when Apple abandoned Samba in favor of its own SMB implementation called SMBX.[31] Apple switched to its own SMBX implementation after Samba adopted GPLv3.[34][35] MacOS also has supported the IETF Network File System (NFS) for many years (and continues to do so as of 2021).

(FN 1) Compliance Recording/Quality Management/Advanced Quality Management (CR/QM/AQM) are 32-bit applications. a. Support for the application client operation on Windows 7 64-bit machines is through WoW64 emulator mode. b. Desktop-based monitoring and recording is not supported in WoW64 mode.(FN 2) Cisco QM has direct dependencies upon Cisco Unified Communications Manager for CTI and SIP events. Therefore, QM compatibility with Unified CM is limited to the current Unified CM version at the time of release and at least one prior version. Previous versions of QM are not generally updated for compatibility with new versions of Unified CM. Therefore, when you plan an upgrade, consult the appropriate QM Installation Guide for Unified CM compatibility. See footnote on individual QM versions to identify the Unified Communications Manager versions that are supported by that QM.(FN 3) All associated Service Updates are supported with compatible versions of WFM.
This section lists the overall status of our FSMO roles. Although Samba does not implement all of them entirely, such operations that go through the FSMO may be quite rare, or in the case of only Samba, perhaps impossible. Not many people would be running (large) mixed domains in the long term and if they are, their domain should be primarily Windows or primarily Samba to avoid issues in compatibility but also with their expectations.
There are a number of functions that are required to be accepted asa Cinder driver. Rather than list all the required functionality in thematrix we include the list of required functions here for reference.
The legacy SMB1 client that is no longer installed by default in Windows 10 or Windows 2019 commercial editions had a more complex (i.e. bad) behavior based on the naïve idea that clients and servers should sign if they feel like it but that it was ok not to sign otherwise, known as "enabled", i.e. "if agrees". Signing is still possible in any case, nothing turns the signing code off. This is not a security model we follow anymore but everyone was wearing 1-strap undone overalls and baggy windbreakers at this point in the 90s and thinking they looked good. SMB1 also had the "required" setting, for those who wanted more strictness, and that will override the "if I feel like it" behavior as you'd hope. So we end up with this complex matrix. Again, it only matters for the SMB1 protocol that you are not supposed to be using.
The table below lists the compatibility of LedgerSMB versions with PostgreSQL versions. Products for which support has ceased due to End-of-Life date being reached are not listed and should not be used.
For real-time help try our Matrix (IRC like) room #ledgersmb - you will usually find most of the core team hanging out there. The most feature-full and commonly used client is Element. It is available as a web client (for computers) and also as Android and iOS clients from within the appropriate app stores. We suggest you create a matrix account as that will allow you to log back in later to see our response to your question.
Please keep in mind that the community (especially the people you may need help from) are scattered around the world and will likely be in a different timezone to you. This means that it can sometimes take quite a few hours before someone responds. (although these days on IRC there is someone around almost all of the time). For email lists this is not a big problem, but if you are using Matrix (directly or via a matrix guest session) you will need to stay connected until someone answers otherwise we have no way to contact you :-)
You can use a browser-based matrix client to join the channel.It defaults to guest access with reduced features, but it is trivial to sign up and get additional benefits like channel history and other things.
In each version of Windows, Microsoft provides an updated version of the Server Message Block (SMB) protocol. Windows Server 2016 and Windows 10 communicate via the new SMB 3.1.1, offering some new features in terms of performance and security. Of course, Windows Server 2016 and Windows 10 can still use SMB to talk to older Windows versions and to Linux without problem (see the "Linux and SMB 3.1.1" box), although you must use an SMB version from the oldest system present. In this article, I introduce the use of SMB 3.1.1 and examine its compatibility issues.
As mentioned before, Windows Server 2016 and Windows 10 can communicate with older versions of Windows; however, you must use SMB version 3.0.2 or earlier for compatibility reasons. The earlier versions do not have the security features, or the (potential) performance gains offered by SMB 3.1.1. Incidentally, this is also true for use with Windows Server 2012 R2 and Windows 8.1. As soon as a server with Windows Server 2016 communicates with a Windows 8.1 client, it uses SMB 3.0.2; likewise, it uses SMB 3.0 for Windows 7 and Server 2012. Significant features for fast and secure data exchange on the network are missing; for example, the opportunity to use multiple parallel access via SMB (SMB Multichannel).
All parameters are filled in from the PRINTER_INFO_2 structure sent by the Windows NT/2000 client with one exception. The "Windows 9x driver location" parameter is included for backwards compatibility only. The remaining fields in the structure are generated from answers to the APW questions.
This option is mainly used as a compatibility option for Visual C++ when used against Samba shares. If oplocks are enabled on a share, Visual C++ uses two different time reading calls to check if a file has changed since it was last read. One of these calls uses aone-second granularity, the other uses a two second granularity. Asthe two second call rounds any odd second down, then if the file has atimestamp of an odd number of seconds then the two timestamps will notmatch and Visual C++ will keep reporting the file has changed. Settingthis option causes the two timestamps to match, and Visual C++ ishappy.
Note that the SMB protocol allows setting attributes whose value is 64K bytes long, and that on NTFS, the maximum storage space for extended attributes per file is 64K. On some filesystem the limits may be lower. Filesystems with too limited EA space may experience unexpected weird effects. The default has changed to yes in Samba release 4.9.0 and above to allow better Windows fileserver compatibility in a default install.
This option is mainly used as a compatibility option for Visual C++ when used against Samba shares. Visual C++ generated makefiles have the object directory as a dependency for each object file, and a make rule to create the directory. Also, when NMAKE compares timestamps it uses the creation time when examining a directory. Thus the object directory will be created if it does not exist, but once it does exist it will always have an earlier timestamp than the object files it contains.
This parameter allows the administrator to configure the string that specifies the type of filesystem a share is using that is reported by smbd(8) when a client queries the filesystem type for a share. The default type is NTFS for compatibility with Windows NT but this can be changed to other strings such as Samba or FAT if required.
The default has changed to no in Samba release 4.9.0 and above to allow better Windows fileserver compatibility in a default install. In addition the default setting of store dos attributes has been changed to Yes in Samba release 4.9.0 and above.
If this parameter is set Samba attempts to first read DOS attributes (SYSTEM, HIDDEN, ARCHIVE orREAD-ONLY) from a filesystem extended attribute, before mapping DOS attributes to UNIX permission bits (suchas occurs with map hidden and map readonly). When set, DOSattributes will be stored onto an extended attribute in the UNIX filesystem, associated with the file ordirectory. When this parameter is set it will override the parameters map hidden,map system, map archive and map readonly and they will behave as if they were set to off. This parameter writes the DOS attributes as a string into the extendedattribute named "user.DOSATTRIB". This extended attribute is explicitly hidden from smbd clients requesting anEA list. On Linux the filesystem must have been mounted with the mount option user_xattr in order forextended attributes to work, also extended attributes must be compiled into the Linux kernel.In Samba 3.5.0 and above the "user.DOSATTRIB" extended attribute has been extended to storethe create time for a file as well as the DOS attributes. This is done in a backwards compatibleway so files created by Samba 3.5.0 and above can still have the DOS attribute read from thisextended attribute by earlier versions of Samba, but they will not be able to read the createtime stored there. Storing the create time separately from the normal filesystem meta-dataallows Samba to faithfully reproduce NTFS semantics on top of a POSIX filesystem.The default has changed to yes in Samba release 4.9.0 and above to allow better Windowsfileserver compatibility in a default install. 2ff7e9595c
