CDE
NAME
  dtspcd - CDE Subprocess Control Service

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

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 terminate 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 protocol 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.

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(8)) in response to a CDE
  client requesting a process to be started on the daemon's host.

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 authentication 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 command 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 system administrator
  to create files of environment variable definitions to be placed in the
  processes environment before a remote process is started. See dtspcdenv(4)
  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.

DIAGNOSTICS
  Use the command line options -log and -debug (described above) to get
  diagnostic information.
