SCSxx05/SCSxx20 User Guide 7: System Administrator and User Functions

7-2

Changing the Root Password

The system administrator must also change the password for the root level.

Although users do not require root access, the system administrator can access

it using SSH. Make sure to know the root access password and be certain that it

has not been left as the common default value. This is especially important if

SSH is enabled, since SSH can offer the ability for root-level access by a remote

system (depending on sysadmin settings).

To change the root-level password of the SCS, follow the procedure below. It

uses the passwd command but with some changes for root level. The default

root password is root.

1. Log in as sysadmin. The command-line prompt displays.

2. Type bash to start a shell process (notice: sysadmin level = $).

3. su (switch user) to root level; enter the existing root password (default =

root). After the system accepts the password, notice that the root level =

sysadmin@SCSXXYY/#.

4. Type passwd to change the root level password. The “authentication tokens

updated” message displays.

5. Type exit to leave root level (sysadmin@ $).

6. Type exit to leave shell level (sysadmin>).

7. Type logout to log out of the system.

Note: Before you SAVE the system data, verify that your new root password is

correct. Repeat step 3, and when you are prompted for a password, enter the

new password.
