MP-RAS Remote Support

Disabling Modem Passwords and Access from UNIX
MP-RAS

From the UNIX MP-RAS environment, you can run the cu utility to disable
modem passwords and auto-answer mode. For more information on the UNIX
MP-RAS cu command, refer to your operating system documentation.

For information about using MP-RAS to define and delete modem passwords,
refer to the “Setting Modem Passwords in UNIX MP-RAS” section later in
this chapter.
