Linux Essential

Linux Basics. It could boring learning the basics of linux as we pore through the command sets, but is important to play around the commands to get use to it. Once we have some hands on and familiar how linux works (for e.g linux is all about plain text files that work together with scripts, daemons, etc), it becomes a useful skill when advancing to more advanced linux configuration. For a start, i would think basic linux training should at least include the following topics:

1. An appreciation topic to tell us why, how and where linux comes from and the need for Open Source OS, services, etc.

2. Some basic commands (or else u be staring at a prompt, not knowing what to do next!): - How to Log into the system, changing users and editing text files. - How to use built-in and online documentation to enhance your experience (those man pages and help files things) - how to browse the filesystem (especially important if u are too use to the GUI in windows)

3. Users, Groups and Permissions: This is important because it is different from dos/windows files. But linux file structure is flexible (e.g setting different kinds of permissions on a file) and stream-lined. Also to note are Advanced Topics in Users, Groups and Permissions (setUID, SetGID, etc). On top of this, learn a bit about partitions, inodes, linking and archiving tools.

4. Scripting. And this include knowing the bash shell, standard input/output aka I/O and pipes (which looks like this ), Text Processing Tools such as grep, cut, sed, sort, diff, patch, find, etc.

5. Know a bit about Vi editor (cos even if u like to use nano, u need to know how to navigate your way when using things like visudo which uses only the vi editor).

6. Linux processes, the cron schedular, etc. I like cron because it automate things nicely. on top of this, it is good to know how to setup networking, web browsing, email client, printing and date & time (use ntp). 7
. Basic System Administration Tools such as how to install linux, its packages, set up simple firewall using netfilter iptables and also how to secure your core using SELinux.

Information Technology Infrastructure Library v3

Introduction

• Information Technology Infrastructure Library (ITIL) is a set of concepts and policies for managing the IT services, developments and operations.
• ITIL gives a detailed description of a number of important IP practices with comprehensive checklists, tasks and procedures that any IT organization can tailor to its needs.

What we will learn in ITIL?

This course has 11 study units, with exercises and assignments spread throughout the course to reinforce the knowledge gained.

• Service Management as a practice
• Service Life cycle
• Generic Concepts & Definitions Key Principles & Models
• Processes
• Functions
• Technology & Architecture Implementation Considerations
• ITIL Qualification scheme Complementary Industry Guidance

Benefits of ITIL

• Increased user and customer satisfaction with IT services
• Improved service availability, directly leading to increased business profits and revenue
• Financial savings from reduced rework, lost time, improved resource management and usage
• Improved time to market for new products and services
• Improved decision making and optimized risk

Green Computing

Green IT refers to environmentally sustainable computing or IT. It is the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems such as monitors, printers, storage devices, and networking and communications systems efficiently and effectively with minimal or no impact on the environment.

• Use power management feature that helps to reduce cooling requirements, noise, operating costs for energy and cooling, and lower power consumption.
• Server Virtualization allows running multiple independent virtual operating systems on a single physical computer.
• VMware ESX Server abstracts processor, memory, storage, and networking resources into multiple virtual machines.
• VMware VMFS allows multiple installations to access the same virtual image.
• VMware Virtual SMP allows a single machine to use multiple processors simultaneously.
• Having a bigger drives help to conserve power to get rid all the older, smaller hard drives and install a new, bigger one. It also has a higher in storage density, which helps to reduce power consumption.
• If replacing 11 legacy drives with a modern, high-capacity drive, eventually get a 16% increase on capacity and use 81% less power. Furthermore, it can save 93% more floor space.
• Economizers that make use of “free cooling”.Going lights (mean improved security, improved response time) improves more than data center energy costs.Obviously the more you limit access, the less cooling escapes as doors are opened and less energy is used to maintain proper temperatures.
• Other less obvious lights out benefits include improved security, reduction in damaged cabling and equipment, less theft and misappropriations of equipment, lowered insurance costs, quicker response times, and better allocation of your IT talent.
• With remote bios level access to servers, the ability to do remote power "cold boots", and the ability to be notified when environmental thresholds are exceeded, IT Managers have the ability to draw on their best IT resources regardless of their physical location. Today's remote access hardware is OS independent and with virtual media enables you to remotely do major software updates and patches.

Conclusion,

Our project is to creating and developing complex network using Packet Tracer 5.2 to simulate in “real-life” network scenario. Even though we have the foundation of technical skill, is a best practice to implement ITIL life cycle to manage and organize the IT infrastructure to deliver more efficiencies and effectiveness to the services. Beside knowing how to manage them well, in the organization, we need to think of going green computing as it can helps to save cost, reduce energy consumption from the data center, going paperless, recycling of raw material.

Enterprise network have bring improvement in efficiency to many companies, as it enable computers in departments and workgroups to be connected to each other. This had in return enabled them to communicate with each other and sending document within the company by using it. As from this you can see that companies and organization are heavily replying on this to operate their work.

Advantage of Enterprise network:

• It helps employee within a company or organization to send or transfer data/document at faster speed.


• It helps to prevent leaking of information to unknown people.


• It improves efficiency on communication between departments within company or organization.


• Help the efficiency of distributing the information or files to the whole department in the shortest time needed

Project Life Cycle

They have adopted this framework as a guideline to run our project implementation throughout the Project Life Cycle (PLC). Every time when a new feature is

added in, it will go through these features and review it.

Project initiation:

We analyze and define the essential materials that are needed for this project. We define the project scope, work breakdown structure to start on our

projects. We also perform phase review (this is to ensure that our project is on track, we also prepared a backup plan for uncertainty risks).

Planning:
At this phase, we work out our project schedule, identified the project activities and determine the resources required. We plan our weekly activities carefully, so we can organize and stick to our project schedule, making sure that we do not lack behind.

Execution:
Execution of the activities that we have planned is done in this phase. This includes setting up of LAMP server and installation of moodle. Doing of Lab practical for CCNA3 and CCNA4 and preparing activity wizards for it.

Next Generation Network (NGN)

A common term used in emerging computer network architectures and technologies that
handles multiple types of traffic (such as voice, data,, multimedia)
convergence of service provider networks which include public switched telephone network, the internet data network and in some instances, the wireless network.
Offers key convergent multimedia services using shared network characterized by essential elements such as:

• A unique and shared core network for all type of access and services.
• A core network architecture which is divided into three layers: transport, control and services.
• Development of packet mode transport( IP flow transport native IP, or on ATM in short term with a progressive convergence to IP)
• Open and standardized interfaces between layers for control and services layer in order to allow third parties to develop and create services independent of the network.
• Support multiple applications (multimedia, real-time, transaction) adaptable of user and growing and varied capacities’ of access networks and terminals.

Benefits of NGN :
Allows the continuation of existing network as well as interoperability with the same network, well in parallel enabling the implementation of new capabilities.
Provides mobility which gives the user and devices the ability to communicate and access services from different locations and technical environments.
With an open architecture certain, service providers can now develop an in-depth expertise and come up with innovative offers.
Improvement in the area of implementation new services. Open technologies maked possible to change a component and to implement new service in a few months.

Technologies / Software used :
Packet Tracer 5.1

It is a Cisco Networking teaching and Learning Software .

Some Function :

Multi-user Capability -enable people that are using packet tracer in different PCs to be able to connect to each other by using it.
This will help to simulate more about Wide Area Network as learner can now ping outside of its own packet tracer instead of within it.

Activity-wizard - It enables teacher to create question and quiz to let learners to do it as a practice instead of just showing, teaching and giving out question through writing out or printing.This will help to improve the process in teaching and at the same time student are able to practice on packet tracer straight away instead of doing it on a piece of paper.

Linksys wireless router, it allow user to create a PC that connect to the router using wireless instead of wired. Since we are always using wireless in the campus when using of our laptops. This would enable student to experience how wireless works on the surface.

Ext. application, right now we still do not have any example for it yet. But it’s a platform where by users are allow to install any extension available for packet tracer to suit their needs.

Advantages of

• Able experience how to configure a switch or router in a vitural world


• A better view on what networking is all about


• Able to test a student knowledge on networking at a faster way, by giving them lab test and practical quiz.

PHP

PHP is a scripting language originally designed for producing web pages. It has been improved to include a command line interface capability. It can also be used in standalone graphical applications.

PHP originally stood for Personal Home Page. It was first started in 1994. The creator, Rasmus Lerdorf, initially created these PHP tools to replace a set a scripts he had been using to maintain his personal homepage. Released publicly on June 8, 1995. Since the first version, PHP has come a long way with new enhancements. With PHP 6 set to be released soon, things are looking bright for PHP.

PHP advantages

• Fast


• Stable


• Secure


• Easy to use


• Open source.

PHP code is inserted directly into the HTML that makes up a website. The code is executed when a visitor comes to the website.

PHP disadvantages
Would need to add JavaScript if he/she wants to do more than just HTML /CSS pags on the client

A little difficult because the way browser work makes handling data and coding program more interesting as the programmer would have to manage varaiables coming in and out and between pages

Open to Security Flaws due to unimplemented or unknown vulernerabilites

Moodle

Moodle is a free and open source e-earning software platform, also known as a course management system or learning management system. Moodle is designed to help educators to create courses with opportunities for rich interaction. Moodle is an open source license that people can develop additional functionality.

Many of our users love to use the many activity modules (such as Forums, Wikis, Databases and so on) to build richly collaborative communities of learning around their subject matter (in the social constructionist tradition), while others prefer to use Moodle as a way to deliver content to students (such as standard SCORM packages) and assess learning using assignments or quizzes.

Fedora

Fedora is a RPM-based, general purpose operating system built on top of the Linux.

It is developed by the Fedora Project and sponsored by Red Hat.
One of Fedora’s main objectives is not only to contain free and open source software, but
also to be on the leading edge of such technologies.

The Fedora Project was created in late 2003, after Red Hat Linux discontinued.
Red Hat Enterprise Linux branches its releases from versions of Fedora. The name of Fedora derives from Fedora Linux, a volunteer project that provided extra software for the Red Hat Linux Distribution.
Before Fedora 7, there were two repositories, Core and Extras. Fedora Core contained base packages that were required by the operating system. Fedora

Extras, the secondary repository that was included from Fedora Core 3, was community-maintained. Since Fedora 7, both repositories have been merged.
Prior to Fedora 7 being released, a third repository, Legacy, was released. However, Fedora Legacy shut down in December 2006.
Fedora 10, codenamed “Cambridge”, was released on November 25, 2008. Its features include faster startup using Plymouth, support of ext4 filesystem, Sugar

Desktop Environment, GNOME 2.24, KDE 4.1.2 and OpenOffice.org 3.0
