Introduction
Congratulations on choosing
Linux For Beginners and thank you for doing
so.
There are plenty of books
on this subject on the market, thanks again for
choosing this one! Every effort was made to ensure it is full of as much
useful
information as possible, please enjoy it!
There are three ways to access a Linux system:
❖
Through a text console. In this method the user connects directly to
the computer that has Linux installed and then they can access it
through a non-graphic system
❖
From a graphical session manager (X Window).
Here the user
connects directly to the computer that has Linux installed and
accesses the system through a graphical program
❖
From a remote computer using telnet or secure shell.
In
any of the previous situations, the following will appear (more or less):
❖
Login: (Username is typed)
❖
Password: (The password is typed, which is not visible on the
screen)
For security reasons the
password must meet certain
conditions such as:
Contain at least six characters
Contain at least one numerical or special character
and two alphabetic characters
Be different
from the login name
The first time the system is accessed, the password used will be the one
provided by the administrator of the system. There are several ways to end
the work session in Linux, depending on whether we are in graphic mode or
text.
In-text mode:
1.
Press the d keys
2. Enter the exit command.
In graphic mode:
The output of X Window depends on the window manager that is running
and will be explained later.
