Abstract This redbook provides information about the key components of the IBM OS/2 Warp Server product. Following on the heels of OS/2 Warp Connect, the integrated OS/2 client operating system, OS/2 Warp Server combines the refreshed OS/2 Warp and LAN Server with a wealth of functional enhancements in TCP/IP, Remote Access Services (LAN Distance), systems management (SystemView), backup and recovery and advanced print function. Each service or function can be selectively installed, allowing users to customize OS/2 Warp Server to meet their specific needs. This redbook describes hints and workarounds for various installation scenarios. The major enhancement to TCP/IP is the dynamic IP introduction. OS/2 Warp Server is the first product which has implemented Dynamic DNS (Domain Name System) together with DHCP (Dynamic Host Control Protocol). This redbook discusses the detail of this protocol and implementation on server and clients. Remote Access Services is equivalent to the existing LAN Distance connection server product but with several enhancements. This redbook describes not only the enhancements but also the basics of remote access services. This redbook intends to provide guidance on planning, installation and customization of the core components of OS/2 Warp Server. The components discussedinthisredbookaretheFileandPrintSharingfunctionwithOS/2and DOS/Windows/Windows 95 client, Adapter and Protocol Services, TCP/IP Services and Remote Access Services. For information on SystemView in OS/2 Warp Server, Backup and Recovery, and Advanced Print Services see the upcoming redbook, Inside OS/2 Warp Server, Volume 2: Using SystemView, Backup/Recovery and Advanced Print which is planned to be available in May/1996. Readers are assumed to have some knowledge of OS/2 Warp, IBM OS/2 LAN Server 4.0 and basics of TCP/IP protocol and products.

  • Configuring DNS

    Configuring DNS

    Configuring DNS The Domain Name System (DNS) is a distributed database in which you can map hostnames to IP addresses through the DNS protocol from a DNS server. Each unique IP address can have an associated hostname. The Cisco IOS software maintains a cache of hostname-to-address mappings for use by the connect, telnet, and ping EXEC commands, and related Telnet support operations. This cache speeds the process of converting names to addresses. Note You can specify IPv4 and IPv6 addresses while performing various tasks in this feature. The resource record type AAAA is used to map a domain name to an IPv6 address. The IP6.ARPA domain is defined to look up a record given an IPv6 address. • Finding Feature Information, page 1 • Prerequisites for Configuring DNS, page 2 • Information About DNS, page 2 • How to Configure DNS, page 4 • Configuration Examples for DNS, page 13 • Additional References, page 14 • Feature Information for DNS, page 15 Finding Feature Information Your software release may not support all the features documented in this module.

    Chapter 1. Origins of Mac OS X

    1 Chapter 1. Origins of Mac OS X "Most ideas come from previous ideas." Alan Curtis Kay The Mac OS X operating system represents a rather successful coming together of paradigms, ideologies, and technologies that have often resisted each other in the past. A good example is the cordial relationship that exists between the command-line and graphical interfaces in Mac OS X. The system is a result of the trials and tribulations of Apple and NeXT, as well as their user and developer communities. Mac OS X exemplifies how a capable system can result from the direct or indirect efforts of corporations, academic and research communities, the Open Source and Free Software movements, and, of course, individuals. Apple has been around since 1976, and many accounts of its history have been told. If the story of Apple as a company is fascinating, so is the technical history of Apple's operating systems. In this chapter,[1] we will trace the history of Mac OS X, discussing several technologies whose confluence eventually led to the modern-day Apple operating system. [1] This book's accompanying web site (www.osxbook.com) provides a more detailed technical history of all of Apple's operating systems. 1 2 2 1 1.1. Apple's Quest for the[2] Operating System [2] Whereas the word "the" is used here to designate prominence and desirability, it is an interesting coincidence that "THE" was the name of a multiprogramming system described by Edsger W. Dijkstra in a 1968 paper. It was March 1988. The Macintosh had been around for four years.

    1. Introduction

    Network Operating Systems Partha Dasgupta Department of Computer Science and Engineering Arizona State University Tempe AZ 85287-5406 USA [email protected] [Note: Written in 1997, Appeared in Encyclopedia of Electrical Engineering] 1. Introduction Network Operating Systems extend the facilities and services provided by computer operating systems to support a set of computers, connected by a network. The environment managed by a network operating system consists of an interconnected group of machines that are loosely connected. By loosely connected, we mean that such computers possess no hardware connections at the CPU – memory bus level, but are connected by external interfaces that run under the control of software. Each computer in this group run an autonomous operating system, yet cooperate with each other to allow a variety of facilities including file sharing, data sharing, peripheral sharing, remote execution and cooperative computation. Network operating systems are autonomous operating systems that support such cooperation. The group of machines comprising the management domain of the network operating system is called a distributed system. A close cousin of the network operating system is the distributed operating system. A distributed operating system is an extension of the network operating system that supports even higher levels of cooperation and integration of the machines on the network (features include task migration, dynamic resource location, and so on) (1,2). An operating system is low-level software controlling the inner workings of a machine. Typical functions performed by an operating system include managing the CPU among many concurrently executing tasks, managing memory allocation to the tasks, handling of input and output and controlling all the peripherals.
