NAME
slpd - 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 service 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 maintains 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
FILES
/etc/inet/slp.conf The default configuration file
slpd.reg The proxy registration file

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 ser-
vice's status can be queried using the svcs(1) command.
