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 net-
     work services.

     slpd provides the following framework services:

          Directory Agent
                This service automatically caches service  adver-
                tisements  from service agents to provide them to
                user agents, and makes directory agent advertise-
                ments  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  for-
                wards   registrations  to  directory  agents.  By
                default, slpd is a service agent server.

          Passive Directory Agent Discovery
                This service listens for directory  agent  adver-
                tisements  and maintains a table of active direc-
                tory agents.  When a user agent  wishes  to  dis-
                cover  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 ser-
                vices are registered by proxy.

     All configuration options are available from the  configura-
     tion file. slpd reads its configuration file upon startup.

     Stop and start the slpd daemon by using the startup  script:
     /etc/init.d/slpd.  Use the command /etc/init.d/slpd stop  to
     stop the slpd daemon. Use the command /etc/init.d/slpd start
     to start it.

     The file /etc/inet/slp.conf must exist  before  the  startup
     script   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# /etc/init.d/slpd stop

     Example 2: Restarting the slpd daemon

     The following command restarts the slpd daemon:

     example# /etc/init.d/slpd start

FILES

     /etc/inet/slp.conf
           The default configuration file

     slpd.reg
           The proxy registration file
