Lucent Technologies 7820-0802-003 manual Changing the Admin password, Securing the serial port

Performing Basic Configuration

Recommended basic security measures

Changing the Admin password

A user who knows the password to the Admin level can perform any operation on the

TAOS unit, including changing the configuration. The Admin password is set to Ascend by default. Lucent recommends that you assign a secret password immediately to prevent unauthorized users from gaining access to the unit by means of the default password.

Following is an example of changing the Admin password:

default> auth admin Password: Ascend

admin> read user admin

USER/admin read

admin> set password = secret

admin> write USER/admin written

Note that the Allow-Password permission is set to No in the Admin login. Although this setting protects the unit’s passwords, it also prevents the Save command from storing passwords in a configuration file. To save passwords in a configuration file, you can set Allow-Password to Yes in the Admin profile, or you can create another User profile for the purpose of backing up the unit and set Allow-Password to Yes in that profile.

Securing the serial port

By default, when users connect to the serial port on the shelf controller, they are logged in with the Admin User profile. To secure the serial port with a username and password, proceed as follows:

1Read the Serial profile:

admin> read serial { 1 17 2}

2Set the User profile to null: admin> set user =

3Set Auto-Logout to Yes:

admin> set auto-logout = yes

This setting automatically logs out the current User profile if the Data Terminal Ready signal (DTR) is lost on the serial port.

4Write the profile: admin> write

Now users connecting to the serial port must supply a valid username and password for access to the TAOS unit through the serial port.

Assigning a Telnet password

Lucent recommends that you assign a Telnet password, which can be up to 21 characters in length, to prevent unauthorized Telnet sessions. A user who opens a Telnet session to the TAOS unit is prompted to supply this password.
