Thursby DAVE

Last updated

DAVE was a commercial grade Microsoft Windows file and print sharing SMB/CIFS software for Apple Macs from Thursby Software Systems [1] .

Microsoft Windows is a group of several graphical operating system families, all of which are developed, marketed, and sold by Microsoft. Each family caters to a certain sector of the computing industry. Active Windows families include Windows NT and Windows Embedded; these may encompass subfamilies, e.g. Windows Embedded Compact or Windows Server. Defunct Windows families include Windows 9x, Windows Mobile and Windows Phone.

DAVE was first introduced in 1996. Microsoft DFS support was added in 2002.

Distributed File System (DFS) is a set of client and server services that allow an organization using Microsoft Windows servers to organize many distributed SMB file shares into a distributed file system. DFS has two components to its service: Location transparency and Redundancy. Together, these components improve data availability in the case of failure or heavy load by allowing shares in multiple different locations to be logically grouped under one folder, the "DFS root".

Thursby co-wrote the Mac SMB/CIFS standards with Microsoft in 2002. [2]

Although it is true that Mac OS X does have Samba support, the built-in SMB support with early OS X versions had limitations that DAVE attempted to overcome, offering better compatibility & performance for enterprise environments and specifically in networked use of Mac apps such as Final Cut Pro, Creative Suite, Avid and Office. [3]

Samba is a free software re-implementation of the SMB networking protocol, and was originally developed by Andrew Tridgell. Samba provides file and print services for various Microsoft Windows clients and can integrate with a Microsoft Windows Server domain, either as a Domain Controller (DC) or as a domain member. As of version 4, it supports Active Directory and Microsoft Windows NT domains.

The ADmitMac and ADmitMac PKI products build on DAVE, adding enhanced support for Microsoft Active Directory and US government Public-key infrastructure systems. [4]

Active Directory (AD) is a directory service that Microsoft developed for the Windows domain networks. It is included in most Windows Server operating systems as a set of processes and services. Initially, Active Directory was only in charge of centralized domain management. Starting with Windows Server 2008, however, Active Directory became an umbrella title for a broad range of directory-based identity-related services.

In 2017, Thursby announced [5] that DAVE and ADmitMac were now end-of-life products, writing:

Thursday, July 27, 2017 (Arlington, TX) - Today Thursby Software Systems, Inc. (Thursby) announced the end-of-life for both their legacy DAVE® and ADmitMac® products for the Apple Macintosh.
DAVE was first introduced in 1996, 21 years ago, as the first Microsoft SMB file-sharing client on the Mac. In 2003, Thursby introduced ADmitMac as the first Active Directory solution for the Mac.
Since that time, Apple has continued to improve their operating system by inclusion of their own SMB and Active Directory technology, in part with the help of Thursby. With the recent announcement of the High Sierra operating system, Thursby believes that Apple has finally culminated a total Microsoft file systems to the quality that eliminates the need for either DAVE or ADmitMac.
Thursby will continue to support customers under contract, but does not expect any enhancements for the next operating system release. Legacy licenses with 30-day configuration support will continue to be available to all customers.

The final versions were DAVE v13 [6] and ADmitMac v10 [7] .

The resource fork is a fork or section of a file on Apple's classic Mac OS operating system, which was also carried over to the modern macOS for compatibility, used to store structured data along with the unstructured data stored within the data fork.

In computer networking, Server Message Block (SMB), one version of which was also known as Common Internet File System, operates as an application-layer network protocol mainly used for providing shared access to files, printers, and serial ports and miscellaneous communications between nodes on a network. It also provides an authenticated inter-process communication mechanism. Most usage of SMB involves computers running Microsoft Windows, where it was known as "Microsoft Windows Network" before the introduction of Active Directory. Corresponding Windows services are LAN Manager Server and LAN Manager Workstation.

Mac OS 8 operating system

Mac OS 8 is an operating system that was released by Apple Computer, Inc. on July 26, 1997. It represents the largest overhaul of the classic Mac OS since the release of System 7, approximately six years before. It emphasizes color more than prior versions. Released over a series of updates, Mac OS 8 represents an incremental integration of many of the technologies which had been developed from 1988 to 1996 for Apple's overly-ambitious OS named Copland. Mac OS 8 helped modernize the Mac OS while Apple developed its next generation operating system, Mac OS X.

Connectix company

Connectix Corporation was a software and hardware company, noted for having released innovative products that were either made obsolete as Apple Computer incorporated the ideas into system software, or were sold to other companies once they become popular. It was formed in October 1988 by Jon Garber; dominant board members and co-founders were Garber, Bonnie Fought, and close friend Roy McDonald. McDonald was still Chief Executive Officer and president when Connectix finally closed in August 2003.

AppleShare was a product from Apple Computer which implemented various network services. Its main purpose was acting as a file server, using the AFP protocol. Other network services implemented in later versions of AppleShare included a print server using the Printer Access Protocol (PAP), web server, electronic mail server, and SMB / CIFS server to support file sharing to Microsoft Windows clients.

HFS Plus or HFS+ is a file system developed by Apple Inc. It replaced the Hierarchical File System (HFS) as the primary file system of Apple computers with the 1998 release of Mac OS 8.1. HFS+ continued as the primary Mac OS X file system until it was itself replaced with the release of the Apple File System (APFS) with macOS High Sierra in 2017. HFS+ is also one of the formats used by the iPod digital music player. It is also referred to as Mac OS Extended or HFS Extended, where its predecessor, HFS, is also referred to as Mac OS Standard or HFS Standard. During development, Apple referred to this file system with the codename Sequoia.

Microsoft Visual SourceSafe (VSS) is a discontinued source control program, oriented towards small software development projects. Like most source control systems, SourceSafe creates a virtual library of computer files. While most commonly used for source code, SourceSafe can handle any type of file in its database, but older versions were shown to be unstable when used to store large amounts of non-textual data such as images, and compiled executables.

The Apple–Intel architecture, or Mactel, is an unofficial name used for Apple Macintosh personal computers developed and manufactured by Apple Inc. that use Intel x86 processors, rather than the PowerPC and Motorola 68000 ("68k") series processors used in their predecessors. With the change in architecture, a change in firmware became necessary; Apple selected the Intel-designed Extensible Firmware Interface (EFI) as its comparable component to the Open Firmware used on its PowerPC architectures, and as the firmware-based replacement for the PC BIOS from Intel. With the change in processor architecture to x86, Macs gained the ability to boot into x86-native operating systems, while Intel VT-x brought near-native virtualization with Mac OS X as the host OS.
