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.
