UNIX is a multitasking, multiuser operating system. This means that
|
|
there can be many people using one computer at the same time, running
|
|
many different applications. (This differs from MS-DOS, where only one
|
|
person can use the system at any one time.) Under UNIX, for users to
|
|
identify themselves to the system, they must <b>log in</b>, which
|
|
entails two steps: Entering your <b>login name</b> (the name which the
|
|
system identifies you as), and entering your <b>password</b>, which
|
|
is your personal secret key to logging into your account. Because only
|
|
you know your password, no one else can login to the system under your
|
|
username.
|
|
<P>
|
|
On traditional UNIX systems, the system administrator will assign you
|
|
a username and an initial password when you are given an account on the
|
|
system. However, because you are the system administrator, you must
|
|
set up your own account before you can login---see
|
|
Section <A HREF="node96.html#seccreateaccount">3.2.1</A>, below. For the following discussions,
|
|
we'll use the imaginary username ``<tt>larry</tt>''.

|
|
In addition, each UNIX system has a <b>hostname</b> assigned to it.
|
|
It is this hostname that gives your machine a name, gives it character
|
|
and charm. The hostname is used to identify individual machines on
|
|
a network, but even if your machine isn't networked, it should have a
|
|
hostname. In Section <A HREF="node190.html#secsethostname">4.10.2</A> we'll cover setting your
|
|
system's hostname. For our examples, below, the system's hostname is
|
|
``<tt>mousehouse</tt>''.
