System Administrator

6-2
How are users managed?
A System Administrator creates new user accounts and assigns users
to groups. The image provides the System Administrator with two
different methods to manage users:
■
The User management utility, accessible by clicking Settings >
User management.
■
Standard command-line tools to manage users - all from the
Console command shell's BusyBox. Letter case matters when
using command line names and option switches.
How do you prevent a user account that is set to
auto logon from being logged in?
Shift
Press the left key as soon as the login screen displays.
How are groups created using BusyBox?
The System Administrator uses the
new group on the t5525.
The /etc directory and the "group" file contain a list of defined
addgroup
groups. The
addgroup [-g GID] group_name [user_name]
"-g GID specify Group ID (gid)
How are file permissions handled using
BusyBox?
The Linux operating system uses file permissions as its basis for
security. A Linux operating system considers all resources and
directories as files within the security structure. File permissions
determine each file's read, write, and execute permissions for all users
and groups on the system. Under Linux permissions, these are in
three groups - owner, group, and others. Each group has three
permission options - read, write, and execute.
