The SPX driver's link to IPX is created and held together by the NetWare Protocol Stack Daemon (NPSD). If NPSD dies, the architecture that links IPX and SPX is destroyed; SPX then reports errors and drops all outbound data. Disconnect indications are generated to all local endpoints. Use the streams trace command, strace(ADM), to monitor errors.
The SPX driver is a STREAMS driver that you must link into the kernel. You must also install:
NPSD must be running to enable the use of SPX. NPSD reads the NPSConfig file as it initializes. That file contains a flag that tells NPSD whether or not to activate SPX. The flag should be set to "active" so that NPSD activates SPX and links SPX to the stack. If NPSD is not running and the flag is not set to ``active'', the t_open call that opens SPX fails.
The SPX driver is accessed through two devices:
There is no read/write interface for SPX.
The tunable parameters for SPX
are in a file called spx_tune.h.
These parameters are described in the
Networking Guide .
