SYNOPSISdtspcd [ -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.
