An SCO Technical White Paper Version 2.1.2 the danger of a single point of failure if a server housing the database went down. NDS provides direct and managed access to all network resources regardless of where they are physically located. This presents a single information system to users and administrators. One of the many benefits of NDS is that users no longer must log into each server they wish to access. Users log directly into the network as a whole and will have automatic access to servers, printers and volumes that the network administrator allows them to see. This broader view of the network is much easier to manage since network objects can be manipulated graphically using the standard NetWare 4.1 administration tools. The directory consists of objects, which are the elemental pieces of the network. Examples of objects would include users and printers but would also include print queues, disk volumes and even NetWare servers. There are numerous different objects types and these are differentiated by the types of properties these objects have. Object properties define what an object is and, to an extent, how it acts within the network. The nature of specific objects is held in the object’s values. So, for example, when a new user is added to the network, a new object of type “user” is added to the NDS database, some of the user object’s properties would include user name, phone number and FAX number and the new user object would be assigned appropriate values for the name, phone number and so on. NetWare 4.1 File Services With NetWare 4.1 File Services, NWS provides network storage capabilities for standard NetWare clients. NetWare clients would notice no difference between a native NetWare 4.1 server and NWS in the normal operations of saving and retrieving files over the network. Files reside on standard SCO UnixWare file systems and can be manipulated using standard UNIX tools as well as NetWare client tools like ndir and ncopy. NetWare uses name spaces to support native file services for a variety of different clients. This is necessary because of the different file storage requirements of the different NetWare clients. For instance, DOS only supports file names of 8 characters with a 3 character extension, while UNIX technology allows 256 character names and Macintosh ® supports long names with embedded spaces. NWS supports names spaces for DOS/Windows 3.1, Macintosh, UNIX and OS/2 systems (note: Windows 95 and Windows NT use OS/2 name space).Access Control to NWS volumes can be handled by either the SCO UnixWare system or by the NetWare mechanism. This is configurable through the NetWare Volume Setup desktop tool that is installed with the system. NetWare 4.1 Print Services NetWare 4.1 print services are totally integrated with native UNIX print services. SCO UnixWare 2.1 users can utilize standard NetWare print services including print servers, print queues and printers. Print Servers are processes running either on SCO UnixWare or on NetWare that route print requests to the correct queues and printers. Print Queues are temporary holding areas where print jobs reside before they are sent to a printer. Because NWS provides standard NetWare 4.1 printing, users have access to printers anywhere they reside on a NetWare or a SCO UnixWare server. This was accomplished by implementing the NetWare NPrinter process on SCO UnixWare 2.1. And because of the NDS features within NWS, NetWare administrators can use standard NDS tools to add new printers to the SCO UnixWare environment and control user access to those printers. 28
Graphical Administration of NWS SCO UnixWare 2.1 The administration of NWS is accomplished by standard NetWare 4.1 administrative tools like Nwadmin as well as a number of easy to use tools on the SCO UnixWare desktop: NetWare_Setup - provides a single view of all NetWare-related administrative capabilities on SCO UnixWare 2.1. It includes the ability to administer parameters relating to IPX/SPX, NWS, NUC, network management and Print Server functions. NWS_Status - shows operating status of NWS and allows administrators to turn the server on and off, and send messages to NetWare client screens NWS_Volume_Setup - allows users to create, delete, repair, optimize and get detailed information about NWS volumes DS_Install - allows administrators to install or remove NDS databases in NWS. DS_Repair - allows standard NetWare repair facilities to be run on the NDS tree created on NWS systems. NWS_Licensing - allows for adding or deleting user license upgrades for NWS client access. NetWare_Client_Disks - allows users to create standard NetWare 4.1 client disks for DOS/Windows and OS/2 clients. NetWare 4.1 Volume Management NetWare volumes are analogous to UNIX partitions. Volumes contain the root of the NetWare file system and a single NetWare server can have up to 64 volumes. NWS utilizes the NetWare Portable File System (NPFS) to implement NetWare volumes on SCO UnixWare. The NPFS is a software layer that allows native SCO UnixWare file systems (like vxfs and ufs) to act as NetWare volumes. NPFS keeps track of NetWare specific filesystem (volume) features and emulates those features on top of the UNIX file system. NWS volume management is done using the NWS_Volume_Setup desktop utility. This utility allows administrators create, delete, repair and optimize NWS volumes. By default, NWS allows up to 10 volumes to be specified although the system can be tuned to allow up to 64 (the current NetWare 4.1 limit). NWS User Management NWS introduces the concept of Hybrid User which provides a linkage for users wanting to access files both as NetWare clients and UNIX users. The hybrid user function handles situations of assigning file and directory ownerships when a user exists in both the SCO UnixWare and the NetWare environments. Administration of this feature is done through the SCO UnixWare 2.1 graphical administration tools. Users will have normal, native access to files and directories in both environments. NWS Backup and Restore All files and components of the NWS environment can be backed up using standard UNIX backup technologies that have been enhanced to take NetWare extended file attributes into account. NDS can also be backed up and restored using tools supplied with the system. SCO UnixWare 2.1 Installation Installation of the SCO UnixWare 2.1 system is fast and largely automatic. Designed to be easy, intuitive and flexible the installation process features: • Installation is Fast and Easy - installation of the system can be accomplished in under an hour without extensive training or even UNIX system experience. Easy menus and graphics walk the user through the install while still allowing expert user a great deal of flexibility. 29
