NAME
     dtspcd - TED Subprocess Control Service

SYNOPSIS
     dtspcd    [ -debug	] [ -log ] [ -auth_dir directory ]	[
     -timeout num_minutes ] [ -mount_point mount_point ]

DESCRIPTION
     The daemon	for the	TED Subprocess Control service,	dtspcd,
     is	not intended to	be started directly by the user, rather
     it	should be started automatically	by the inetd daemon (see
     inetd(1M))	in response to a TED client requesting a process
     to	be started on the daemon's host.

OPTIONS
	-auth_dir  directory
		       The default authentication directory is
		       the user's $HOME	directory.  This option
		       allows the system administrator to use a
		       different directory.  Note that directory
		       must be exported	to hosts wishing to use
		       the dtspc service.
		       directory - the name of the directory to
		       use for authentication.

	-timeout  minutes
		       By default, the dtspcd process will ter-
		       minate if it does not have any activity
		       (process	start or process stop) for 10
		       minutes and dtspcd has no child processes
		       running.	 To change the timeout,	set
		       minutes to the desired number of	minutes.
		       To force	the daemon to not use a	timer,
		       set minutes to -1.
		       minutes - the number of minutes for the
		       timer.

	-mount_point  mount_point
		       The file	system's mount point is	named
		       mount_point.  For example, mount_point
		       could be	"/net" or "/nfs".  The daemon
		       sets the	environment variable DTMOUNTPOINT
		       to the value of mount_point.  This value
		       of DTMOUNTPOINT will override all other
		       definitions of DTMOUNTPOINT.

	-log	       This option turns on logging of status
		       information to the file
		       /var/dt/tmp/DTSPCD.log.	The information
		       logged includes the name	of the client
		       host, the client's username, error

		       messages	and the	name of	the file used for
		       authentication.	The default is to not do
		       any logging.

	-debug	       This option turns on logging of dtspc pro-
		       tocol to	the file /var/dt/tmp/DTSPCD.log.
		       The protocol information	logged includes
		       the name	of the protocol	and number of
		       bytes in	the request.  The default is to
		       not log the protocol.

AUTHENTICATION
     When a TED	client attempts	to connect to a	dtspcd daemon,
     the client	sends the daemon its username.	The daemon uses
     the username to determine the user's home directory on the
     daemon's host.  The home directory	is used	during authenti-
     cation and	it must	be readable by the daemon and writable by
     the client.  Therefore, the user's	home directory on the
     daemon's host must	be mounted to the client host.	If the
     user's home directory is not readable and the -auth_dir com-
     mand line option is not used, the directory /var/dt/tmp will
     be	used.

     To	use a directory	other than the user's home directory for
     authentication, use the -auth_dir command line option.

CONFIGURATION
     The dtspcd	daemon is an Internet service that must	be
     registered	in the file /etc/services as follows:

	  dtspc	     6112/tcp

     and in the	file /etc/inetd.conf as	follows:

	  dtspc	 stream	 tcp  nowait  root  /usr/dt/bin/dtspcd/usr/dt/bin/dtspcd

ENVIRONMENT VARIABLE MANAGEMENT
     The TED Subprocess	Control	service	allows the user	and sys-
     tem administrator to create files of environment variable
     definitions to be placed in the processes environment before
     a remote process is started.  See dtspcdenv(4M) for more
     information.

OPERATING SYSTEM DEPENDENCIES
     On	HP-UX, the file	/usr/adm/inetd.sec may be used to control
     access to the dtspcd daemon.  See inetd.sec(4) for	more
     information.
