Cisco TelePresence ISDN Link

Contents

Introduction

Password protection

The system is password protected in the following ways:

• The ISDN Link is password protected. You always need to

enter a username to sign in to the command line interfaces.

• You can protect the file system of the ISDN Link by setting

a password for the root user. The root user is disabled by

default.

NOTE:

Make sure to keep a copy of the password in a safe

place. If you have forgotten the password and cannot access

the system, you need to do a factory reset via the boot monitor.

If you do not know how to do this contact Cisco support.

Getting started

Configuration examples

Changing the system password

The system is delivered with a default user account with

username admin and no password set. This user has full access

rights to configuration of the system.

NOTE:

We strongly recommend that you set a password for the

admin user to restrict access to system configuration.

Changing the password using the command line interface

If a password is currently not set, use a blank current password;

to remove a password, leave the new password entries blank.

1. Connect to the ISDN Link through the network or serial port.

2. Sign in to the unit with your current password.

3. Run the following API command and when prompted enter the

current password and the new password, and confirm the new

password:

systemtools passwd

The password format is a string with 0–64

Setting a root password

If you sign in to the command line interface as root, you can

access the file system on the unit.

The root user is disabled by default. You can check if root is

enabled or disabled by entering the following API command:

systemtools rootsettings get

The command will respond with On if already enabled.

Perform the following steps to activate the root user and set a

password:

1. Connect to the ISDN Link through the network or serial port.

2. Sign in to the system with the username (admin) and

password.

3. Run the following API command:

systemtools rootsettings on [password]

characters.

Where [password] is the password (optional) you want to

set.

NOTE:

Although password is optional we strongly

recommended that a password is set and some record made

of this password. Having no root password, if root user is

enabled, poses a serious security risk.
