Administering SCO IPX/SPX

How IPX/SPX works

SCO IPX/SPX provides interoperability between DOS Workstation NetWare clients and SCO OpenServer systems over the NetWare network. It also provides the transport protocols used by SCO Gateway for NetWare to communicate with NetWare file and print servers. It eliminates the need for multiple protocol stacks in a Novell network, providing greater efficiency and lower administrative overhead. SCO IPX/SPX consists of the three components: kernel, user, and DOS.

Kernel component

This component is comprised of the following drivers:

User component

This component includes the following protocols by which the SCO OpenServer system can advertise itself to NetWare clients:

DOS component

This component consists of an executable that allows a DOS client to establish a connection to the UNIX server. The NVT.EXE executable is a terminate-and-stay-resident program (TSR) and acts as a network redirector, allowing a DOS end user to establish a connection with an NVT server. For more information about installing the DOS component and using NVT.EXE, see ``Installing and using the DOS component''.

In addition to NVT.EXE, the DOS client must be running a NetWare protocol support module to provide the IPX protocol support and the device driver for the LAN card used in the DOS client machine. Currently, there are two prevalent IPX protocol modules and a terminal emulator provided by Novell:
