=LEARNING ABOUT YOUR MATRIX SERVER ACCOUNT=
===Main Objectives of this Practice Tutorial===
:* Understand the purpose of the '''Matrix server''' and the <u>'''advantages'''</u> of combining Linux servers to form a '''cluster'''.
:* List the steps to connect to your Matrix server account in the <u>'''computer labs</u> at Seneca College'''.
:* List the steps to connect to your Matrix server account from a computer <u>'''outside</u> of Seneca College'''.
:* Working with the Linux '''Command Prompt''' (Linux '''shell''')
:* Changing your Matrix Account '''Password'''

:* Performing '''Review Questions''' for Additional Practice
===Purpose of Having a Matrix Account===
While attending Seneca College, you will be using many different computer systems to perform various operations.
Some of these servers include:
{|width="100%" cellspacing="0"
|-
| style="padding-left:0px;width:10%" |'''my.senecacollege.ca'''

[[Image:cli-prompt.png|thumb|right|150px|A '''shell''' is simply an interface / interpreter to allow a user to communicate with the Linux computer system. ]]
Although you need to study concepts throughout this course, you will also need to learn to '''issue and memorize simple as well as more advanced Linux commands'''. This requires that you practice issuing Linux commands on a frequent basis to become more comfortable when working the Unix and '''Linux command-line environments'''.
Just like with other operating systems like MS Windows, it is important to learn how to '''open a command prompt in order to issue Linux commands to perform common Linux OS tasks'''. In Unix/Linux, a '''shell''' is simply an interface / interpreter to allow a user to communicate with the Linux computer system (server). Linux shells have evolved (improved) over a period of time. You will be using the '''Bash Shell''' which is considered to be user-friendly.
The '''Matrix''' server has been configured to allow users to '''only interact with the Linux OS by issuing commands'''. There are various reasons for this, but the main 2 reasons are to '''force students to learn how to issue Linux commands''' as well as '''limitations to remote access to a graphical Linux serve'''r due to large number of users (students).
Later in the course, your instructor may discuss other ways of accessing '''graphical versions of Linux''', and how to launch a shell terminal.
===Layout of the Matrix Server===
[[Image:matrix-layout.png|thumb|right|350px|The Matrix server consists of several Virtual Computers all connected together to form a '''cluster'''. A cluster is a cost effective alternative to larger servers. ]]
The Matrix server consists of '''several Virtual Computers connected together''' to form a '''cluster'''. A cluster is a cost effective alternative to buying larger servers.
All registered students in this course have access to an account on the Matrix server.
You will be using this account for the following reasons:
:* Issuing '''Linux commands'''
:* Becoming productive using the Linux '''command prompt''' ('''shell''')
:* Performing '''Linux Practice Tutorials'''
:* Performing '''Linux Assignments''' ('''3''')
:* Practice Issuing '''Linux Command Review Questions'''
In the next section, you will learn how to '''connect''' to and '''login''' to your Matrix server account both at a '''college lab workstation''' and from a remote computer such as your '''home computer''' or your '''laptop computer'''.
=INVESTIGATION 1: ACCESSING YOUR MATRIX LINUX ACCOUNT=
In this section, you will learn how to access your Matrix Linux account by two different methods:
:* From a workstation '''within''' a '''Seneca College lab'''
:* From your <u>own</u> computer '''within''' or '''outside''' '''Seneca College'''
===Part 1: Accessing your Matrix Account from a Seneca College Lab ===
x
:'''Perform the Following Steps:'''
# Start your workstation in your lab and login to your Seneca Windows account.
# Make certain that the MyApps browser is open (if not, double-click on the MyApps icon on the desktop to launch)
# In the MyApps window, click on the search area and type the word: ssh
# Several SSH applications will appear. All of these applications allow you to connect to your Matrix account. We will use the application called SSH Client for this practice tutorial.
===Part 2: Access your Matrix Account From your own computer within or outside Seneca College ===
x
:'''Perform the following steps:'''
# Select from the installation menu: '''Install CentOS 7'''.
# Next, you will be prompted for a language. In the first screen, select language '''English''' with subselection '''English-Canada''' and then click the '''Continue''' button on the bottom right-hand screen.

= LINUX PRACTICE QUESTIONS =
The purpose of this section is to obtain extra practice to help with your assignment #1, quizzes, your midterm, and your final ezam.
Here is a link to the MS Word Document of ALL of the questions displayed below but with extra room to answer on the document to
simulate a quiz:
https://ict.senecacollege.ca/~murray.saul/uli101/uli101_week1_practice.docx
Your instructor may take-up these questions during class. It is up to the student to attend classes in order to obtain the answers to the following questions. Your instructor will NOT provide these answers in any other form (eg. e-mail, etc).
'''Review Questions:'''
# What is a “Linux Cluster”? What is an advantage of using a Linux cluster?
# List three unique server names at Seneca college and briefly explain the purpose of that server.
# List the steps to connect and login to your Matrix Linux server account from a workstation on one of your labs at Seneca College.
# List the steps to connect and login to your Matrix Seneca College account on your home computer.
# List 3 unique ways to log out of your Matrix account (not including closing the SSH window or application).
# List the steps to change your Matrix password.
# What is the difference between a Linux command and an argument?
# What character(s) can separation between commands and arguments?
