PollCat NetLink II - User’s Guide
C. Administrator Functions and
User Functions
In order to restrict access to sensitive commands, NetLink II offers two
separate operating modes; Administrator Mode and User Mode.
Administrator Mode allows access to all command functions, including
those used to setup and configure the NetLink II unit. User Mode allows
limited access to command functions; users are able to invoke commands
to review status and read data, but are not allowed to change system
parameters.
C.1. Security Mode at Start Up
NetLink II will display a login prompt each time you attempt to access
command mode. The login name and password entered at this prompt
determine whether you will be allowed to invoke Administrator Mode
command functions, or if you will be limited to User Mode commands.
Login names and passwords are defined via a user account, as described in
Section 5.3.1.
In the default state, NetLink II provides one user account that permits
access to Administrator Mode (login/password = "SUPER"), and one
account that only permits access to User Mode (login/password =
"SMDR".) Note however, that you can also delete these two default
accounts and define new accounts via the User Directory function as
needed.
C.2. Dialback Security
The Dialback Security feature provides an additional level of protection
for modem access to command mode functions. When this feature is
configured and enabled, NetLink II will display a password prompt when
contacted via modem. If the caller enters a valid password, NetLink II will
hang up, and then dial the user-defined dialback number for the password
entered.
If desired, the Dialback Security feature can also be configured to re-display
the password prompt, and require the login information to be re-entered
when the user's modem answers the dialback call. For more information,
please refer to Section 5.4.4.1.
