  1. Network clients Unit objectives • Describe the network clients that are available to connect DOS-, Windows-, and Macintosh-based computers to a network

  2. Topic A • Topic A: Network client review

  3. Network client review • Network clients provide the connectivity between the server and the individual workstations in any client/server network configuration • The choice of which client to use is driven by the choice of which operating system is being used

  4. DOS clients • DOS is an operating system that doesn’t provide for network connectivity • A DOS-compatible client must be installed to provide connectivity from the DOS workstation to the server • DOS is limited to having only onereal-mode client loaded at any one time • Note that “real-mode” is the older mode that x186 processors used, when a maximum of 1MB of memory was available. “Protected mode” was introduced with the x286s, in the late 80s.

  5. Windows 3.x clients • Windows 3.x doesn’t support protected-mode network clients • This means that only one 3.x client can operate at any one time; the different clients would otherwise be competing for the same memory space. • Some Windows 3.x clients are: • Artisoft LANtastic • Novell NetWare • Banyan VINES • Microsoft Network Client

  6. Windows for Workgroups 3.x clients • Windows for Workgroups 3.x is a peer-to-peernetworking version of Windows 3.x • Network client optionsinclude: • Artisoft LANtastic • Novell NetWare • The Banyan VINES client • The Microsoft Network Client • Same as the clients

  7. Windows for Workgroups 3.x • The evolution of Windows operating systems is a story of moving slowly away from a DOS-based kernel. • In 3.x, this process had barely begun, if at all. • 3.x is really a DOS OS with a simple GUI on top or it. • This being the case, it has the same networking limitations that DOS has. • The evolution with 3.x, however, lies in its ability to be configured to support external clients. (See the list on the previous slide) • There is also a peer-to-peer version of 3.x.

  8. Windows 95 clients • Windows 95 supports both the newer, protected-mode network clients and older, real-mode ones. • Clients include: • Banyan VINES DOS/Windows 3.1 client • FTP Software NFS client (InterDrive 95) • Microsoft’s Client for Microsoft Networks • Microsoft’s Client for NetWare Networks • Novell NetWare Workstation Shell 3.x • Novell NetWare Workstation Shell 4.0 and above (VLM) • SunSoft PC-NFS (5.0)

  9. Network components • From “Client” you can add either of 95’s two protected-mode clients: • - “Client for Microsoft Networks” • - “Client for NetWare Networks”

  10. Windows 98 clients • Includedprotected-mode clients: • Client for Microsoft Networks • Client for NetWare Networks • Microsoft Family Logon • A number of 3rdparty, protected-mode clients also can be added – IBM, Banyan, etc. • Includedreal-mode clients: • Banyan DOS/Windows 3.1 client • FTP Software NFS Client • Novell NetWare (NETX) • Novell NetWare ( VLM)

  11. Windows NT/2000/XP clients • Windows NT/2000/XP: • Provides built-in support for Microsoft and Novell NetWare networks • Compared with Windows 95 or 98, the support for multiple types of networks isn’t as robust • Doesn’t provide inherent support for real-mode network clients • (probably because they are very old apps that can hardly run on a system with newer hardware; this support simply isn’t needed any more) • The connectivity to Windows-based networks is installed by default • The book describes how to configure different NOSs and versions to connect to each other: page15-8ff.

  12. The Network utility in Windows NT

  13. Adding a client in Windows 2000/XP

  14. Activity A-1 page 15-9 Discussing Windows network clients

  15. Macintosh clients • Apple Macintosh computers come fully equipped with their own networking software, AppleTalk • With the network software, Macs can easily be networked together • Majority of the Macintosh clients in the business world participate in a Windows NT or Novell NetWare environment • Macs are much more fully-integrated with Windows and other OSs than they used to be. They share printers and files without extensive user configuration.

  16. Macintosh clients • OS X and AppleShare use different methods to interact with other OSs. • AppleShare has it’s own client for connections with itself, Windows, etc – AppleShare Client. • OSX uses Samba, which uses Server Messenger Blocks (SMB). Wikipedia on Samba: • Samba provides file and print services for various Microsoft Windows clients and can integrate with a Windows Server domain, either as a Primary DomainController (PDC) or as a domain member. • It can also be part of an Active Directory domain. Samba runs on most Unix and Unix-like systems, such as Linux, Solaris, AIX and the BSD variants, including Apple's Mac OS X Server(which was added to the Mac OS X client in version 10.2).

  17. Novell NetWare clients • Novell offers a network client that can be installed and configured on a workstation for network connectivity • The Novell Client provides a graphical utility to log in from Windows and the capability to access network files and printers through Windowsdialog boxes • NetWare and Macs have a number of utilities to help them to interact: • “NetWare Client for Macintosh has a login to take you directly to the Mac functions • “Print Chooser” and “Volume Mounter” are just a couple of several convenient utilities

  18. Novell NetWare clients • Novell Client offers access to: • All Novell releases, from 2.x to 6.x • Windows OSs from 3.x and DOS to XP and Vista • Novell Client gives you 32-bit functionality • It can connect simultaneously to both the older directory, NDS (Novell Directory Services) and the current standard, eDirectory.

  19. Activity A-2page 15-12 Macintosh and Novell NetWare clients

  20. Unit summary • Described the network clients that are available to connect DOS-, Windows-, and Macintosh-based clients to a network
