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(8). 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(7), under the service identifier:

svc:/network/slp


Administrative actions on this service, such as enabling, disabling,
or requesting restart, can be performed using svcadm(8). The
service's status can be queried using the svcs(1) command.
