The PATHWORKS for SCO UNIX software allows Intel 386/486-based com- puters running the SCO UNIX System V/386 operating system (SPD 32.52.xx), or SCO MPX operating system (SPD 32.74.xx), or SCO Open Desktop op- erating system (SPD 32.57.xx) to provide network services to DOS and OS/2 users. PATHWORKS for SCO UNIX works in conjunction with PATHWORKS for DOS and PATHWORKS for OS/2 client software to integrate personal computers into the Digital computing environment. 2 PATHWORKS for SCO UNIX server can offer file, print, and management services to personal computer users. It allows users to share appli- cations, data, and valuable computing resources. Information can be accessed from local and remote systems, and that information can be applied to DOS and OS/2 applications. PATHWORKS for SCO UNIX supports the DECnet (Phase IV), TCP/IP, and Net- BEUI network transports. DECnet and TCP/IP offer both local area net- work (LAN) and wide area network (WAN) environments, while NetBEUI of- fers only a LAN environment. The SCO UNIX server supports multiple trans- ports at the same time. See the System Support Addendum for the de- tails regarding Network Interface Cards supported and the restrictions regarding the use of concurrent multiple transports. Features PATHWORKS for SCO UNIX provides the following services for personal computers running PATHWORKS for DOS and/or PATHWORKS for OS/2 client software: o Network transport support o NetBIOS[TM] interface support o LAN Manager V2.2 API support o File services o Printer services o Mail services o Server management and control o Domain support o Network logon services o Replication services o Remote boot services 3 Network Transport Support PATHWORKS for SCO UNIX supports DECnet, TCP/IP, and NetBEUI network transport software. One or more of the transport stacks can work con- currently on the server. Any restriction on the use of multiple trans- ports is described in the System Support Addendum (SSA 42.85.01-x). When DECnet for SCO UNIX (SPD 34.21.xx) network transport software is used in conjunction with PATHWORKS for SCO UNIX, personal computer clients can access servers in both LANs and WANS. Both DOS and OS/2 clients are supported by PATHWORKS for SCO UNIX by means of the DECnet net- work transport running on the server and the DECnet transport running on the DOS or OS/2 clients. The TCP/IP transport is provided through the use of SCO TCP/IP soft- ware (SPD 32.56.xx). SCO TCP/IP software does not come as part of SCO UNIX or SCO MPX and has to be separately purchased. TCP/IP software comes as part of ODT. Customers using PATHWORKS for SCO UNIX in the DECadvantage system en- vironment are required to employ traditional UNIX security and must use TCP for DECadvantage (SPD 42.11.xx) on top of SCO UNIX or SCO MPX. ODT is not supported under DECadvantage platform. Client support for the TCP/IP transport is currently available for PATH- WORKS for DOS and OS/2 clients. Some DOS and OS/2 client functional- ity is not supported under TCP/IP. Refer to PATHWORKS for DOS (SPD 55.07.xx), PATHWORKS for DOS (TCP/IP) (SPD 33.45.xx), PATHWORKS for OS/2 (SPD 55.24.xx), and PATHWORKS for OS/2 (TCP/IP) (SPD 36.58.xx) for detailed informa- tion on supported features. NetBEUI transport software comes as part of the PATHWORKS for SCO UNIX software. The NetBEUI transport for the DOS client is available as LAN Manager V2.1 Add-On kit for PATHWORKS for DOS (QA-0TLAG-(HB or H7)) and can be used along with PATHWORKS for DOS V4.1A. NetBEUI transport for the OS/2 client is included in PATHWORKS for OS/2 V2.0 or higher. Using NetBEUI transport, DOS and OS/2 clients can access the server in the LAN for file and print services. 4 Refer to the SOFTWARE REQUIREMENTS section of this document for in- formation on required network transport software. NetBIOS Interface Support PATHWORKS for SCO UNIX supports the NetBIOS interface in DECnet, TCP /IP, and NetBEUI networks. NetBIOS support under TCP/IP includes a B- node RFC 1001/1002 implementation. NetBIOS interface support includes the support of multiple transport stacks on one or more network con- trollers. LAN Manager V2.2 API Support PATHWORKS for SCO UNIX supports the full set of LAN Manager V2.2 Ap- plication Programming Interfaces (API) including Named Pipes and Mail- slots. This allows the development and support of distributed appli- cations. File Services PATHWORKS for SCO UNIX file shares provide DOS and OS/2 clients with a remote file system that appears as a transparent extension of the client system's local computing environment. PATHWORKS for SCO UNIX file shares are based on Microsoft LAN Manager Extended SMB (Server Message Block) protocols. Each DOS or OS/2 file stored in a file share is stored as a SCO UNIX file. The files stored in a file share are accessible to personal com- puter clients, SCO UNIX users, and to applications that can interpret the contents and the organization of the file as written by the client application. The server also allows client applications to read files written by a SCO UNIX user or application. Multiple DOS and/or OS/2 clients can concurrently access files stored on the server through the file access modes and byte range locking sup- port that is provided by the SCO UNIX Operating System. Because PATH- WORKS for SCO UNIX supports the native SCO UNIX Lock facility, it is 5 possible to develop SCO UNIX-based applications that share data files with personal computer-based applications. PATHWORKS for SCO UNIX file shares are supported on NFS[R] (Network File System), allowing remote NFS files to be shared by PATHWORKS for DOS or PATHWORKS for OS/2 clients. The NFS files can be made avail- able to PATHWORKS clients by means of a PATHWORKS for SCO UNIX file service. Further information on controlling access to server resources is pro- vided in the Server Management and Control section of this SPD. Printer Services PATHWORKS for SCO UNIX software allows DOS, OS/2, and SCO UNIX users to share printers connected to Intel 386/486-based servers. Printer shares are available in LAN and WAN environments. PC clients can print files from the DOS and OS/2 operating systems as well as from PC ap- plications. The system administrator can assign a printer service name to an SCO UNIX printer class. The PATHWORKS for DOS and PATHWORKS for OS/2 client software redirects printer output from a client printer logical name to the defined printer share. The PATHWORKS for SCO UNIX server administration utility (pwmgr) can be used to create printer shares. Printer queues can also be set up using native SCO UNIX utilities. Refer to the System Support Adden- dum (SSA 42.85.01-x) for a list of supported printers. Shared Client Printers PATHWORKS for SCO UNIX support access not only to printers connected to the server, but also to printers connected to DOS clients. These printers are called shared client printers. 6 Once designated as a shared client printer, a client printer can print jobs sent by users from any kind of client. This feature provides ad- ditional flexibility in configuring the LAN, allowing shared print- ers to be put close to users. Mail Services PATHWORKS for SCO UNIX includes PCSA mail support with this release. To use PCAS mail, the SCO UNIX mail system must be installed and con- figured on the SCO UNIX system. The mail server software that is part of PATHWORKS for SCO UNIX pro- vides DOS and OS/2 clients with the ability to send and receive elec- tronic mail messages. A mail account is established on the SCO UNIX server for each PC user. Mail can be sent to this account by other per- sonal computer users as well as users of UNIX and VMS mail software. The PATHWORKS for SCO UNIX mail server provides the personal computer user with folder, local and remote distrubution lists, and delivery capabilities. Realtime notification of new messages can be optionally enabled by the client. Server Management and Control Four styles of server management interfaces are supported by PATHWORKS for SCO UNIX: 1. A simple menu-driven utility called pwmgr at the server console 2. A command line net interface at the server console, or at enhanced DOS client, or at OS/2 client 3. A window-based client interface for enhanced MS-DOS[R] clients run- ning Microsoft Windows called netadmin interface for Windows[TM] 4. A full-screen, menu-based program available for Microsoft OS/2 clients call the net admin interface pwmgr 7 The pwmgr is a simple task-oriented interface that prompts the user to select one of the many relevant tasks. It requires no knowledge of the SCO UNIX Operating System commands for use. The pwmgr utility al- lows the system administrator to: o Manage file and printer shares, user accounts, and groups o Display and control server resources currently in use, such as ac- tive sessions, connections, services, and server statistics o View context-sensitive Help for each menu item and prompt The system administrator can limit the number of simultaneous client connections to a particular share. This allows the system administra- tor to control access to DOS and OS/2 applications that are stored on the server to ensure compliance with vendor licensing agreements. Other restrictions on the use of the server can be imposed to help meet per- formance and security goals. File share access may be controlled through username, password, and group permission. In addition, the pwmgr utility is used to modify the server configuration. Command Line net Interface In addition to the pwmgr utility, a command line net interface is pro- vided to perform all server management tasks from the SCO UNIX sys- tem prompt at the server console or from system prompts at the DOS or OS/2 terminal emulation window. These net commands may be used to add or delete file shares, stop the file server. They may also be used in script files. You must have PATHWORKS for SCO UNIX administrative priv- ileges to use this interface. netadmin Interface for Windows The netadmin interface for Windows provides yet another alternative for controlling the server functions from a client environment. This is a full-screen, windows-based administration program available on PATHWORKS clients running the enhanced redirector and Microsoft Win- dows. This interface is shipped as part of the PATHWORKS for SCO UNIX software and is available in the DOSUTIL share. 8 net admin Interface The net admin interface is a full-screen, menu-based administration program available on PATHWORKS for OS/2 clients. Domain Support PATHWORKS for SCO UNIX allows you to subdivide the network into ad- ministrative groupings of servers and clients called domains. A do- main is a group of servers and clients on a LAN. Domain is the basic unit of network administration and each server running PATHWORKS for SCO UNIX can be a member of a single domain. A user can have accounts in multiple domains, but can logon to only one domain at a time. Domain lockout occurs after a configurable number of unsuccessful lo- gon attempts. The user account is disabled and administrative action is required at the primary domain controller to re-enable the user ac- count. Network Logon Services Running the netlogon service forces the validation of users' logon re- quests. The logon server that processes the request checks its copy of the domainwide user accounts database for the user name and pass- word supplied in the logon request. Each server running the netlogon service has one of the three roles: 1) primary domain controller, 2) backup domain controller, or 3) member server. The netlogon service ensures that each backup domain controller's and member server's copy of the domainwide user accounts database is always identical to the master copy on the primary domain controller. A server running the user- level security without logon validation is called a standalone server. The standalone server does not participate in a domain and has its own user accounts database, which is administered individually. A user logged on a standalone server cannot access the domain's servers that are run- ning the netlogon service, except by using a guest account. The net- logon service is limited to the LAN. Replication Services 9 PATHWORKS for SCO UNIX provides a file replication mechanism that al- lows a set of files to be selectively replicated. The replication ser- vice ensures that any updates to the replicated files are propagated in a timely manner to all servers that are maintaining replicas of the information. The replication service provides: 1) replication of a di- rectory tree or set of directory trees from any server to any set of servers and/or workstations, and 2) capability to dynamically add or delete from the set of directory trees being replicated or to add or delete servers. Remote Boot The PATHWORKS for SCO UNIX Remote Boot service is based on Microsoft's LAN Manager Remoteboot service. The LAN Manager implementation is, in turn, based on the Remote Program Load (RPL) protocol and the NetBEUI protocol. With PATHWORKS for SCO UNIX, you can also remote boot work- stations that use the MOP protocol. The Remote Boot service, running on a PATHWORKS for SCO UNIX server, supports DOS and Windows workstations that boot using the server's hard disk instead of their own local hard disks. Each participating work- station has a network adapter card that retrieves startup and config- uration software from the PATHWORKS for SCO UNIX server when the work- station boots. The PATHWORKS for SCO UNIX Remote Boot service supports the following remote boot workstations: 10 o Workstations with network adapters with RPL ROM chips that use the RPL protocol o Workstations that use Digital's DEPCA and EtherWORKS adapters (but not the EtherWORKS III adapters) with MOP ROMS o Workstations that use Digital's DEPCA, 3Com 3C503 and 3Com 3C523 adapters that use floppy remote boot diskettes HARDWARE REQUIREMENTS Intel 386/486-based systems as specified in the System Support Adden- dum (SSA 42.85.01-x).
