Configuring a Remote Support Modem
2-14
MP-RAS Remote Support
In this case, call-back passwords are required for security reasons.
Console redirection should be ENABLED by default and the modem set
for auto-answer with one or more call-back numbers defined.
A user can then dial into the modem, enter the password, receive the call-
backs and perform necessary remote debug, configuration and update tasks. In
addition, if more expert support is required, you can define a call-through
password remotely.
You can use the following methods to define a call-through password:
•
The “Set Remote Password” Diagnostic Partition or Platform CD-ROM
menu option
•
An operating system application that transmits manually entered modem
(AT) commands to COM1 or COM2
Refer to the “Using a Remote Password” section later in this chapter.
Note: Enable call-through passwords only for the minimum time necessary to
debug and correct a system problem.
Other Modem Security Issues
The modem provides many different features. The “Remote Support” utilities
do not use some of these features.
Predefined Telephone Numbers
One of the features that is not used is the ability to store predefined telephone
numbers within the modem. This represents a security risk for your system.
The modem stores pre-defined phone numbers in the same data space as call-
back and call-through passwords. Therefore, a predefined telephone number is
also interpreted as a valid password.
It is recommended that you not store telephone numbers in the modem.
