IFN507 Network Systems
Assignment 01 – Practical Problem Solving Tasks (25 Marks)
Document Version 1.0 on Tuesday 23 July 2019 (Week 1)
Assignment Due: 11:59pm Sunday 8 September 2019 (Week 7)
This is a Group-of-Three assignment. While group-of-two is also acceptable, an individual attempt needs to be well justified and approved in advance by the unit coordinator. This assignment is worth 25 marks.
The assignment requires your research and practice. The objective of the assignment is to solve network problem tasks by using your knowledge and experience acquired from your research as well as the first six weeks of IFN507 lectures, tutorials and practicals. The outcome of the assignment is a report on your solutions to the given tasks.
Submit an assignment report of no more than 30 A4 pages through theBlackboard. With a cover page and a table of contents, the report should be in pdf format. The assignment is due:
11:59pm Sunday 8 September 2019 (Week 7).
1. Problem Solving Task 1: Remote Desktop (8 Marks)
What do you need for this task?
Two computers remotely interconnected over computers.
What to do?
Sub-Task 1).    Set up Remote Desktop Connection between the two computers;
Sub-Task 2).    Design some scenarios for remote desktop operation; and
Sub-Task 3).    Operate the remote computer from the local computer for the designed scenarios.
For sub-task 1), there are different scenarios depending on what operating systems you use on the two computers. Possible operating systems are Windows 7, Windows 10, Linux (e.g., Ubuntu), and Mac OS. Identify the operating system/s used on the two computers, and find the way for Remote Desktop Connection.
In Windows 7, there is a “Remote Desktop Assistance” graphic interface”, and also a “Remote Desktop Connection” program. Find out how to use them.
In Windows 10, there is a “Quick Assist” to use for remote desktop assistance.
In Mac computers, you may use Remote Desktop client for Mac with Windows apps, resources, and desktops from your Mac computers.
To access a Linux server from Windows, you may try Xming + PuTTY, or other solutions. Find out how to do it. 
Then, set up remote desktop connection, record and report the process (with some photos or screenshots preferably).
For sub-task 2), scenarios you may design are: copy or move a file from one folder (directory) to another; create a file, edit a file, open an image, write an email and send it, etc.
For Sub-task 3), operate the remote computer from the local computer, record and report the process (with some photos/screenshots preferably). 
2. Problem Solving Task 2: Remote Connection (5 Marks)
What do you need for this task?
Two computers interconnected over networks.
What to do?
Sub-Task 1):     Set up remote connection of the two computers for file operations (You may try SSH, for which there are some app clients with a graphical interface, e.g., PuTTY);
Sub-Task 2):    Conduct file operations through this remote connection
Move (push) a file from the local computer to the remote computer;
From the local computer, rename a file on the remote computer;
Download a file from the remote computer to the local computer;
From the local computer, delete a file on the remote computer.
Record and report the processes of these file operations (with some photos/screenshots preferably).  
3. Problem Solving Task 3: Virtual Machine (5 Marks)
What you need for this task?
            A computer with Internet access.
What to do?
            Sub-Task 1):     Set up a Virtual Machine (VM) using Oracle VirtualBox, and show it works.
Sub-Task 2):    Set up a small network using several virtual machines.
For sub-task 1), If you have already set up such a VM (or another type of VM), retrieve and report your VM settings, and show evidence that the VM works. The evidence could be some photos/screenshots with descriptions.
If you do not have a VM on your computer, set up such a VM, report your VM settings, and show evidence that the VM works. The evidence could be some photos/screenshots with descriptions.
For sub-task 2), Copy the virtpc1, virtpc2, virtpc3 and virtpc4 from local machines in lab by going to C:VirtualBoxVM. Design some scenarios to set up a small network using the virtpc1-4. Record and report the processes of your network (with some photos/screenshots preferably).  You may get help from Week06 practical.
4. Problem Solving Task 4: IPv4 Subnetting (5 Marks)
Given a network address 129.99.0.0/16, develop a variable-length addressing scheme that best fits the requirements shown below in the table (AS: Autonomous System). Show your design process.
AS No.

5. Reflections (2 Marks)
Your report should include a separate section of reflections. In this section, each student is asked to write a paragraph in your report to reflect on what you have achieved so far from this unit, and specifically from this assignment. This gives you an opportunity to reflect on what you have learned and also what you think you need to improve. Your reflections are expected to be specific to yourself (not general to others).
