NAME    [Toc]    [Back]

     sdpd - Session Directory Server Daemon

SYNOPSIS    [Toc]    [Back]

     /usr/OnRamp/bin/sdpd [-a mcast_addr] [-p mcast_port] [-r root_dir]	[-d]

DESCRIPTION    [Toc]    [Back]

     sdpd listens for multicast	announcements on the network (as observed by
     the server), maintains an updated list of these announcements, and	makes
     them available to clients through the use of the .sdr mime	type suffix.
     sdpd also maintains a list	of locally created announcements, broadcasting
     the information periodically.  The	sdpd server supports Mbone
     announcements of type SPD V1, SPD V2, and SGI Radio.

OPERATION    [Toc]    [Back]

     sdpd listens on multicast address 224.2.127.255 and port 9876 for SDP
     V1.0, multicast address 224.2.127.254 and port 9875 for SDP V2.0, and
     multicast address 239.7.7.0 and port 58002	for SGI	Radio announcements.
     The V2.0 address can be altered with the -a and -p	options	(see below.)

     Locally created announcements are broadcast every 15 minutes on multicast
     address 224.2.127.254, port 9875.

     sdpd is launched at system	startup	time.  The operation of	the server is
     controlled	by the setting of the chkconfig	sdpd option.  The
     /etc/init.d/run-sdpd {start,stop} script is provided to allow one to stop
     or	start the server manually after	the chkconfig sdpd option is
     appropriately set.

OPTIONS    [Toc]    [Back]

     -a	  mcast_addr specifies multicast IP address to listen on for version 2
	  announcements.  (The default value is	224.2.127.254.)

     -p	  mcast_port specifies UDP port	to listen on for version 2
	  announcements.  (The default value is	9875.)

     -r	  root_dir specifies the root directory	for the	two subdirectories,
	  sdpd-send and	sdpd-out, containing the locally created announcements
	  and the received announcements respectively.	(The default value is
	  /usr/ns-home/httpd-gateway/docs/webface/apps.)

     -d	  Process runs in debug	mode.  Process does not	daemonize.  Network
	  information is sent to stderr.
