Basics

The administrator is responsible for operation of the LCS60; this includes verifying connections, maintaining the network, monitoring the operation, collecting data, backing up and restoring files, starting and stopping protocols, and generating reports. All administration is done after the LCS60 is configured (see Chapters 3 – 7). Administration can be performed at the system console or from a remote terminal.

Logging On

The most powerful user is root, often referred to as the superuser. The superuser may access, alter, or remove any file on the system. Only the superuser has the freedom to do all of the tasks needed to administer an LCS60. To restrict the users with superuser privileges give the root password only to approved users.

Caution: To protect the system from unauthorized changes, it is strongly urged that only the system administrator, and a minimum number of other knowledgeable users approved by the system administrator (ideally this number is zero), be allowed access to the system as the superuser.

The administrator must log on as root to configure the system. (As shipped, the password is the Return key.) Change the root password whenever the security provided by the current password is suspected of having been compromised.

Only the superuser can change the password for root. To change the password, use the passwd root command.

Note: The commands in the Config and Manager directories require root permission and will initially prompt the administrator for the root pass- word. The symbol # will appear at the end of the prompt (e.g., Top>Config>#) once the administrator has root permission.

Note: root can only log on at the system console. The system can be administered remotely, however, as long as the administrator has the root password and the lcsadm remote administration feature has been enabled.
