DT-6061 User's Manual - Platform (Build 16.0)
11/12/04 Datatek Applications Inc. 22
The rule for most U.S. time zones (and the default for START and STOP) is:
START=1SunApr2:00 STOP=5SunOct2:00
which declares that daylight savings starts on the first Sunday of April at 2 a.m. and ends on the
last Sunday of October at 2 a.m.
6.5 CHANGE PASSWORD
Syntax: chgpass OLD=<old> NEW=<new> CONFIRM=<new>
The chgpass command is used to change a user password on the system console. The
command is only allowed if the user is logged in.
All three parameters can be given on the same line as the command. None of those entries are
echo-suppressed. However, if parameters are omitted from the command line, the console will
prompt for them, and the responses will be echo-suppressed. (Previous versions of the DT-6061
used PASSWD and NEWPASS instead of OLD and NEW; the old variations are still supported.)
If the current password is valid and the two entries for the new password match, the password is
changed to the new value.
6.6 RESET PASSWORD
Syntax: rstpass
The DT-6061 has a user changeable password that is used to gain access to the console. If the
password should become misplaced, console access would not be available for configuration and
administration. The user may recover from this situation using the rstpass command. This
command is always available regardless of whether the console is logged in or not. The rstpass
command displays unique identification about this particular device along with a specially
constructed access code and then prompts for the key. The user may then contact the
manufacturer with the device information and access code to obtain the software key.
The software key is an eight character alphanumeric that is valid one time only for this particular
DT-6061. If a valid key is entered the user password is reset to the original value of initial. If an
invalid key is entered the message "key is not valid for this system" is generated.
6.7 SYSTEM PARAMETER CONFIGURATION
Syntax: ipaddr <d.d.d.d> (ip address)
submask <d.d.d.d> (subnet mask)
gateway <d.d.d.d> (gateway router address)
The above commands configure, or verify, the addressing and routing parameters of the DT-
6061. When one of these commands is invoked without its argument, it will display the current
configuration of the unit. When invoked with its argument, the current configuration is changed
accordingly.
The gateway must belong to the same subnetwork as the module. That is, the part of the
gateway address corresponding to the non-zero part of the submask must match the
corresponding part of the ipaddr. If it is necessary to reconfigure a DT-6061 to a new
subnetwork, first set the gateway to none, then change the ipaddr, then set the new gateway.
Changes to these system parameters do not become effective until after the next reboot.
