  11. NetWare File System • Novell Storage Services (NSS): • 64-bit interface • Files or directories up to 8 TB • A trillion files in single directory • File compression • User and directory space restrictions • Advanced fault-tolerance techniques • Efficient use of memory • Browser-based volume management • Split volumes over multiple storage devices Network+ Guide to Networks, 4e

  12. NetWare File System (continued) • NSS-based system may have up to four partitions • One must be a DOS partition • Primary boot partition • Unlimited volumes on each partition • Volumes are basis for organizing files and directories • NSS can combine free storage space from multiple storage devices into a storage pool • Provides flexibility • iManager: GUI tool used to manage objects Network+ Guide to Networks, 4e

  13. NetWare File System (continued) Figure 10-3: A storage pool in Novell Storage Services Network+ Guide to Networks, 4e

  14. eDirectory • NetWare 6.5’s directory database • System for organizing and managing multiple servers and their resources • Similar to Active Directory in Windows Server 2003 • Treat every networked resource as separate object with distinct attributes • Objects belong to classes • eDirectory information stored in database that supports LDAP • Compatible with other NOS and Internet directories Network+ Guide to Networks, 4e

  15. eDirectory (continued) Figure 10-4: eDirectory objects Network+ Guide to Networks, 4e

  16. eDirectory (continued) • Schema: defined set of object classes and their properties • Base schema: simple schema installed by default with eDirectory • Extended schema: changes made to base schema • Trees and OUs: • Hierarchical organization • Tree can have one root • Tree Object Network+ Guide to Networks, 4e

  17. eDirectory (continued) • Trees and OUs (continued): • Below root is an organization object • Branches out in hierarchical arrangement of OUs • A user is a leaf object • Naming Conventions: • Each eDirectory tree object has a context • Indicates where object belongs in the tree • Consists of object’s OU names, arranged from specific to general, plus organization name • Typeful and typeless contexts Network+ Guide to Networks, 4e

  18. eDirectory (continued) Figure 10-5: A simple eDirectory tree Network+ Guide to Networks, 4e

  22. Planning for Installation • Poor planning results in more work for installer, potential downtime for users, and headaches for whomever supports server after installation • Critical preinstallation decisions: • Where does the server fit in the eDirectory tree? • After server’s context established, cannot change it • What name will the server have? • How many and what kinds of NICs will the server use? • What protocols and network services should the server use? Network+ Guide to Networks, 4e

  23. Planning for Installation (continued) • Critical preinstallation decisions (continued): • What will the Administrator password be? • What kind of disk controllers does the server have? • How many, how large, and what kind of volumes will the server require? • Initially all free space on hard disk assigned to default volume, SYS • What server pattern, or type, will the server be? • What kind of license do I have? • How can I remember all of this information? Network+ Guide to Networks, 4e

  24. Installing and Configuring a NetWare 6.5 Server: The Installation Process • Installed from CD or another server on network • Installation tasks: • Select language • Select regional settings • Accept License Agreements • Choose Default or Manual installation • Prepare boot partition • Choose pattern • Select components to install (Manual installation) • Copy files Network+ Guide to Networks, 4e

  25. The Installation Process (continued) • Tasks to set up server: • Name server • Enable cryptography • Specify network protocols for each network adapter • If TCP/IP, specify server’s IP addressing information • Enter server’s host and domain name • New eDirectory tree or add server to existing tree? • Enter eDirectory information • Choose an Administrator ID and password • Select login method Network+ Guide to Networks, 4e

  26. Establishing Users and Groups • Need to add objects—including user objects—to eDirectory tree • Use ConsoleOne, Remote Manager, or iManager • To run ConsoleOne, computer must have ConsoleOne client installed • Running same protocols as server • To run Remote Manager, point Web browser to IP address of server management interface • By default, port 8008 on server Network+ Guide to Networks, 4e

  27. Establishing Users and Groups (continued) • To start iManager, point browser to /nps/imanager.html page on server • After eDirectory objects created, may want to change properties • Home directory: directory in which user can store files • By default, users have full access privileges to files and subdirectories within their home directories Network+ Guide to Networks, 4e

  30. Client Services • Several ways for different types of clients to access server and its resources • Traditional client access • Native file access • Browser-based access Network+ Guide to Networks, 4e

  31. Traditional Client Access • Clients running Windows, Macintosh, and UNIX-type of OSs traditionally connected via a Novell client specifically designed for that client • Client must have appropriate protocol suite installed • May require additional client software • Novell provides utilities to automatically install client software (and updates) on all clients Network+ Guide to Networks, 4e

  32. Traditional Client Access (continued) Figure 10-10: Novell Login dialog box Network+ Guide to Networks, 4e

  33. Native File Access • NetWare capable of providing clients with direct access to NSS using clients’ native file access protocols • Users can browse folders and directories as if connected to server running same file access protocols • All file access protocols installed by default • Network administrator must set up network share for each protocol • Via iManager Network+ Guide to Networks, 4e

  34. Native File Access (continued) • Client must run same protocols and software normally used to connect to a server natively running its file access protocols • NetDrive: When installed on Windows clients, allows access to directories on NetWare 6.5 server • Uses IPs such as HTTP and FTP Network+ Guide to Networks, 4e

  35. Native File Access (continued) Figure 10-11: NetDrive connection dialog box Network+ Guide to Networks, 4e

  36. Browser-Based Access • Users can navigate directories and manage files via Novell’s NetStorage tool • Only need to have TCP/IP protocols installed and configured • Uses standard Internet application protocols • Users connect to URL on server • By default, server’s IP address (or host name) plus /NetStorage Network+ Guide to Networks, 4e

  37. Internetworking with Other Operating Systems • Novell has adopted LDAP directory standards • DirXML:Novell’s tool for integrating eDirectory and Windows Active Directory or Windows NT domain data • Can synchronize Windows and Novell server’s directories • Can configure so that Active Directory or eDirectory is authoritative source for directory information Network+ Guide to Networks, 4e

  38. Internetworking with Other Operating Systems (continued) • Nterprise Linux Services: Simplifies NetWare access for users running Linux NOS • Client tools for accessing eDirectory • Development tools for integrating Linux servers with DirXML • Browser-based file and print services • Novell purchased two companies that write and distribute Linux software • NetWare 7.0 will combine NetWare and Linux kernels • Full compatibility Network+ Guide to Networks, 4e

  39. Summary • With NetWare 6.x, Novell has maintained its NOS’s traditional file- and print-sharing strengths while adding browser-based management tools; popular open source Web development tools; a fast, efficient file system; and flexible methods for managing multiple servers, volumes, and storage objects • The NetWare Integrated Kernel is responsible for overseeing all critical NetWare server processes • NLMs are routines that enable the server to run a range of programs and offer a variety of services Network+ Guide to Networks, 4e

  40. Summary (continued) • Using ConsoleOne, administrators can manage servers, volumes, disks, and eDirectory objects • iManager is the primary means of managing eDirectory objects in NetWare 6.5 • NSS offers many advantages over traditional file systems, including faster access, more efficient use of memory, file compression, support of files or directories as large as 8 TB, support for sharing a single application over multiple servers, capability to limit user directory and volume size, and browser-based management tools Network+ Guide to Networks, 4e

  41. Summary (continued) • eDirectory is NetWare 6.x’s system for organizing and managing multiple servers and their resources, including storage devices, users, volumes, groups, printers, and so on • The word “schema” refers to eDirectory’s defined set of object classes and their properties • eDirectory follows a tree structure • Each object has a context that indicates where that object belongs in the eDirectory tree • NetWare recognizes two naming conventions for a user’s context: typeful and typeless Network+ Guide to Networks, 4e

  42. Summary (continued) • User and Group objects can be created through ConsoleOne, Remote Manager, or iManager • Clients can connect to a NetWare 6.5 server, browse directories, and manage files in one of several different ways • NetWare 6.5 uses the DirXML tool to share data between eDirectory and Active Directory or Windows NT domains • Nterprise Linux Services integrates NetWare and Linux clients and servers Network+ Guide to Networks, 4e
