    NAME
         dtspcd - CDE Subprocess Control Service
    
    SYNOPSIS
         dtspcd    [ -debug ] [ -log ] [ -auth_dir directory ]      [
         -timeout num_minutes ] [ -mount_point mount_point ]
    
    DESCRIPTION
         The daemon for the CDE 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 CDE 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 CDE 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 CDE 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.
