System Administrator FAQs
Q: What Administrator tools come with the Linux 2.4 kernel?
A: None. The kernel does not contain Admin tools, as these come from various open source sites and
are sometimes packaged as part of a Linux distribution. To conserve the t5515's memory space the
image utilizes BusyBox which is a consolidated utility binary.
BusyBox is a single small executable that combines many of the common Linux/Unix utilities. These
utilities are usually smaller versions with less options than their full-featured desktop utilities
counterpart. Because BusyBox has been written to optimize size and for limited resources it is an
excellent choice for an embedded Linux operating system. A good online source for BusyBox follows.

The image contains the following commands. Some are stand alone, and most are limited scope
versions provided via BusyBox)
Q: How are Users managed?
A: A System Administrator creates new user accounts and assigns the users to groups. The image
provides the System Administrator with standard command-line tools to manage users; all from the
Console command shell's BusyBox. Remember letter case matters when using command line names
and option switches.
