NetInfo

Last updated

NetInfo was a distributed network configuration database in NeXTSTEP and Mac OS X versions up through Mac OS X Tiger (10.4). NetInfo stored network-wide configuration information, such as users and groups, in a binary database consisting of directories that could optionally be obtained from a domain server. NetInfo replaced many Unix system configuration files, though they are still present for running the machine in single user mode; most Unix APIs wrapped NetInfo instead.

History

NetInfo was introduced in NeXTSTEP version 0.9, and replaced both the Unix system configuration files and Sun Microsystems' Network Information Service (Yellow Pages) on NeXT computers. It immediately caused controversy. Not only was NetInfo unique to NeXT computers (although NeXT later licensed NetInfo to Xedoc, an Australian software company who produced NetInfo for other UNIX systems), DNS queries went through NetInfo. [1] This meant basic tasks such as translating a UNIX UID to a user name string could stall because NetInfo was stuck on a DNS lookup. At first, it was possible to disable NetInfo and use the Unix system files, but starting in NeXTSTEP version 2, this disabled DNS support. Thus, NeXT computers became notorious for locking a user out of everyday tasks because a DNS server had stopped responding.

The Mac OS X version of NetInfo remedied this (and many other problems), but by this time popular alternatives had emerged. Apple moved away from using NetInfo towards LDAP.. Mac OS X Tiger (10.4) was the last version to support NetInfo. Beginning with Mac OS X Leopard (10.5), NetInfo was completely phased out and replaced by a new local search node named dslocal, which uses standard property list files in /var/db/dslocal/. [2]

Files

The NetInfo Database was stored in /private/var/db/netinfo/local.nidb/, and could only be accessed by root. It could also be viewed and modified through its application programming interface, the NetInfo Manager utility, or command line tools such as niutil.

As NetInfo was completely removed from Mac OS X Leopard (10.5), the NetInfo utilities have been phased out and replaced by other tools.

Data

NetInfo had directories for the following data:

The history of the graphical user interface, understood as the use of graphic icons and a pointing device to control a computer, covers a five-decade span of incremental refinements, built on some constant core principles. Several vendors have created their own windowing systems based on independent code, but with basic elements in common that define the WIMP "window, icon, menu and pointing device" paradigm.

NeXTSTEP is a discontinued object-oriented, multitasking operating system based on the Mach kernel and the UNIX-derived BSD. It was developed by NeXT Computer, founded by Steve Jobs, in the late 1980s and early 1990s and was initially used for its range of proprietary workstation computers such as the NeXTcube. It was later ported to several other computer architectures.

Mac OS X Server is a series of discontinued Unix-like server operating systems developed by Apple Inc. based on macOS. It provided server functionality and system administration tools, and tools to manage both macOS-based computers and iOS-based devices, network services such as a mail transfer agent, AFP and SMB servers, an LDAP server, and a domain name server, as well as server applications including a Web server, database, and calendar server.

Darwin is the core Unix-like operating system of macOS, iOS, watchOS, tvOS, iPadOS, audioOS, visionOS, and bridgeOS. It previously existed as an independent open-source operating system, first released by Apple Inc. in 2000. It is composed of code derived from NeXTSTEP, FreeBSD, other BSD operating systems, Mach, and other free software projects' code, as well as code developed by Apple.

OpenStep is an object-oriented application programming interface (API) specification developed by NeXT. It provides a framework for building graphical user interfaces (GUIs) and developing software applications. OpenStep was designed to be platform-independent, allowing developers to write code that could run on multiple operating systems, including NeXTSTEP, Windows NT, and various Unix-based systems. It has influenced the development of other GUI frameworks, such as Cocoa for macOS, and GNUstep.

The history of macOS, Apple's current Mac operating system formerly named Mac OS X until 2011 and then OS X until 2016, began with the company's project to replace its "classic" Mac OS. That system, up to and including its final release Mac OS 9, was a direct descendant of the operating system Apple had used in its Mac computers since their introduction in 1984. However, the current macOS is a UNIX operating system built on technology that had been developed at NeXT from the 1980s until Apple purchased the company in early 1997.

A/UX is a Unix-based operating system from Apple Computer for Macintosh computers, integrated with System 7's graphical interface and application compatibility. It is Apple's first official Unix-based operating system, launched in 1988 and discontinued in 1995 with version 3.1.1. A/UX requires select 68k-based Macintosh models with an FPU and a paged memory management unit (PMMU), including the Macintosh II, SE/30, Quadra, and Centris series.

A home directory is a file system directory on a multi-user operating system containing files for a given user of the system. The specifics of the home directory are defined by the operating system involved; for example, Linux / BSD (FHS) systems use /home/⟨username⟩ or /usr/home/⟨username⟩ and Windows systems since Windows Vista use \Users\⟨username⟩.

The Dock is a prominent feature of the graphical user interface of macOS. It is used to launch applications and to switch between running applications. The Dock is also a prominent feature of macOS's predecessor NeXTSTEP and OPENSTEP operating systems. The earliest known implementations of a dock are found in operating systems such as RISC OS and NeXTSTEP. iOS has its own version of the Dock for the iPhone and iPod Touch, as does iPadOS for the iPad.

In computing, a directory service or name service maps the names of network resources to their respective network addresses. It is a shared information infrastructure for locating, managing, administering and organizing everyday items and network resources, which can include volumes, folders, files, printers, users, groups, devices, telephone numbers and other objects. A directory service is a critical component of a network operating system. A directory server or name server is a server which provides such a service. Each resource on the network is considered an object by the directory server. Information about a particular resource is stored as a collection of attributes associated with that resource or object.

Mac OS is the series of operating systems developed for the Macintosh family of personal computers by Apple Computer, Inc. from 1984 to 2001, starting with System 1 and ending with Mac OS 9.
