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 DiscoverThis 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 ATTRIBUTES

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. SunOS 5.10 23 Aug 2004 slpd(1M)
