This chapter describes how the system administrator and users gain access to
the system and the functions permitted for each role. It includes the following
topics.

System Administrator Functions 7-1
User Access and Functions 7-3
System Administrator Functions
The system administrator specifies settings such as user IDs, device
configuration, and terminal and access rights to suit the application. The system
administrator is also responsible for configuring the system to work in your
network.
The system administrator initially uses Telnet or a terminal to access and
configure the SCS, and may choose to use the Web-based interface to update
the configuration.
Note: Please see the Configuration chapter for instructions on logging
on and logging out as the system administrator.
Security and Passwords
The SCS uses Linux/UNIX commands to administer the system. The system
administrator and the users access the system using a shell interface, which
limits what they can affect in the operating system.
Note: This guide discusses applicable Linux commands only.
The shell offers the appropriate level of administration while maintaining the
integrity of the system. The system administrator should change passwords upon
installation to protect the system.
The sysadmin programming level is as close to “root” as is required to administer
the SCS, but it is not the most senior root level. The most senior root level is
intentionally removed from the shell; however, it exists in the system and the
system administrator must change its password to protect against unauthorized
access or changes.
Changing the Sysadmin Password
The system administrator must change the password for the sysadmin level
before connecting the SCS to a network or making it accessible to others. The
passwd command is discussed in the Commands chapter.
