To keep workstations from attaching to a server, network supervisors can
turn off the “Get Nearest Server” SAP option.
By default, an SA sends SAP packets to each of its connected network
segments every 60 seconds.
Related utilities: “nwsapinfo(1M)”; “nwsaputil(1M)”.

Service Advertising Protocol daemon (SAPD)
A daemon that performs the functions of the SAP agent that are independent
of NetWare services.
When created by the NPS daemon, the SAP daemon opens a stream to IPX
and sends a request to all SAP agents to send their server information.
From the response packets, the SAP daemon forms a Server Information
Table. The SAP daemon then maintains that table, adding, deleting, and
modifying server information as services are added, deleted, or rerouted on
the network.
UNIX system services can advertise their availability by sending the SAP
daemon a periodic broadcast packet. The SAP daemon adds these services to
its Server Information Table, informs other SAP agents that a new service is
available, and then responds to all queries about these services.
The services remain in the table as long as the services send the SAP
daemon a broadcast every 60 seconds. When a service informs the SAP
daemon that it is going down, the SAP daemon removes the service from its
table, informs other SAP agents that the service is going down, and then
quits responding to queries about the service.
