6.2 Sys Admin vs. root access

The System Administrator (sys admin) has the ability to run the sysadmin functions of the

system. In order to run the Setup command, the System Administrator must change to the root

user. Below is a list of commands accessible by the different admin levels:

The Sys Admin must sign on, and then switch to root level (requires root password) so that they

may run the Setup command. The default root password is 'root'. This root password should be

changed as soon as the System Administrator has gained access to the system.

To Change the root-level password of the SCS3230, follow the steps below.

1. Log in as sysadmin (you see the bash prompt) = sysadmin@SCS3230 /tmp$

2. su to root level; you must enter the existing root password (default = root)

3. After password is accepted, notice root level = root@SCS3230 /var/tmp#

4. Use passwd to change root level password

5. After successful, 'authentication tokens updated' message is displayed. You are

returned to the root level prompt = root@SCS3230 /var/tmp#

6. Use exit to leave root level (sysadmin@SCS3230 /tmp$)

7. Use logout to log out of the system

If you lose the root password, there is no 'back door' password or higher-level access. The

Flash memory device would have to be replaced in order to regain access to the system. Your

existing data on that Flash device would be inacessible.

Only the root level password has access to the SAVE feature which can invoke permanent

changes to the system's memory and features. Turn the system power off without using SAVE

will cause any system changes to be lost.
