nwcm -s console_device=/dev/fd/1
Since NetWare Services operates as a set of daemons, input to the system is
not possible through the console device. All maintenance and server
commands are executed through appropriate utilities (for example,
“NetWare Server Status” and “Directory Services Repair”).
Related utility: “nwcm” (Utilities Reference).
Server protocol
Procedures that a NetWare server follows to accept and respond to
workstation requests.
See “NetWare daemon.”
Service Advertising Protocol (SAP)
A protocol that provides a way for service nodes, such as NetWare servers,
print servers, NVT2 servers and gateway servers, to register their services
and addresses on the IPX internetwork. Clients can then query these tables
for available services and their IPX address.
Routers and servers maintain a server information table and can be referred
to as SAP agents. The Server Information Table contains, among other
fields:
• Server name
• Server type
• IPX internet address
• Hops to server
Servers advertise their services with SAP, allowing SAP agents (SAs) to
create and maintain a database of current internetwork server information.
SAs send periodic SAP broadcasts to keep all SAs on the internetwork
synchronized. SAs also send SAP update broadcasts whenever they detect a
change in the internetwork configuration.
Workstations can query the network to find a server by broadcasting SAP
request packets. When a workstation logs in to a network, it broadcasts a
“Get Nearest Server” SAP request and attaches to the first server that replies.
