NAME
slpd - Service Location Protocol (SLP) Daemon
SYNOPSIS
configuration_file] registration_file] log_file] pid_file]
DESCRIPTION
The daemon provides the functionality of the Directory Agent and Service Agent for the Service Location Protocol ("SLP") version 2. SLP
provides a scalable framework that allows the networking applications to discover the existence, location and configuration of networked
services in the enterprise networks.
provides the functionality of the following services:
This agent collects service advertisements from the service agents or applications providing the services and caches them in its memory.
The DA then provides this services information to the clients (user agents) trying to discover the service information. Directory agents
advertise their presence through directory agent advertisements.
This server registers the service information of all the services that are advertised by the corresponding service agents to this server.
It then answers the queries from the user agents about the information on the services that were registered with this server by the ser-
vices agents. It also forwards the registrations to any Directory Agents that may be present in its scope.
also provides a option whereby the existing services which are not slp enabled can advertise information by storing this information in a
static registration file. See below for the options. reads this file and provides the information to the user agents.
can be either started as an SA server or DA by setting to either false or true in the configuration file. In both the cases, runs as a
daemon listening for SLP requests. When is acting as a DA, it registers the services coming from within the host acting as a SA server and
acts as DA for the User Agents (UAs) running on the remote machines.
can be configured to provision services within a scope that is configured by the administrator by setting in the configuration file. SLP
daemon will answer to requests only if it falls within this scope. This feature of scoping of SLP daemon provides provisioning of services
in an Enterprise network based on administration needs, geographical needs or department needs and also provides scalability.
See RFC2608 for more information on the Service Location Protocol. Without any arguments, reads the default configuration file,

To restart the daemon, send it a signal.
To kill the daemon, send it a signal.
The command can also be used for sending signals to the server process (see the slpdc(1M) manpage).
DIAGNOSTICS
Any errors encountered by in the registration or configuration file or in normal operation are logged in the log file, which is the default
file. To change this log file, use the command.
