SLPD(1M)SLPD(1M)NAMEslpd - Service Location Protocol Daemon
SYNOPSIS
/usr/lib/inet/slpd [-f configuration-file]
DESCRIPTION
The slpd daemon provides common server functionality for the Service
Location Protocol ("SLP") versions 1 and 2, as defined by IETF in RFC
2165 and RFC 2608. SLP provides a scalable framework for the discovery
and selection of network services.
slpd provides the following framework services:
Directory Agent
This service automatically caches service advertisements from ser‐
vice agents to provide them to user agents, and makes directory
agent advertisements of its services. This service is optional.
slpd does not provide directory agent service by default. Directory
agents are not databases, and they do not need to be maintained.
Service Agent Server
All service agents on the local host register and deregister with
this server. This service responds to all requests for services,
and forwards registrations to directory agents. By default, slpd is
a service agent server.
Passive Directory Agent Discovery
This service listens for directory agent advertisements and main‐
tains a table of active directory agents. When a user agent wishes
to discover a directory agent, it can simply query slpd, obviating
the need to perform discovery by means of multicast. By default,
slpd performs this service.
Proxy Registration
This service can act as a proxy service agent for services that
cannot register themselves. slpd reads the proxy registration file
for information on services it is to proxy. By default, no services
are registered by proxy.
All configuration options are available from the configuration file.
slpd reads its configuration file upon startup.
Stop and start the slpd daemon using svcadm(1M). Use the command
svcadm enable network/slp to start the slpd daemon. Use the command
svcadm disable network/slp to stop it.
The file /etc/inet/slp.conf must exist before the slp service can start
the daemon. Only the example file /etc/inet/slp.conf.example is present
by default. To enable SLP, copy /etc/inet/slp.conf.example to
/etc/inet/slp.conf.
OPTIONS
The following options are supported:
-f configuration-file
Specify an alternate configuration file
EXAMPLES
Example 1 Stopping the slpd daemon
The following command stops the slpd daemon:
example# svcadm disable network/slp
Example 2 Restarting the slpd daemon
The following command restarts the slpd daemon:
example# svcadm restart network/slp

NOTES
The slpd service is managed by the service management facility, smf(5),
under the service identifier:
svc:/network/slp
Administrative actions on this service, such as enabling, disabling, or
requesting restart, can be performed using svcadm(1M). The service's
status can be queried using the svcs(1) command.
