IT 477 Converge networks Illinois State University School of information technology Spring 2021 Lab 1

Name: Yashika Mhatre

Part I: Hands-on Lab Procedure 1. Create a AWS account a. Go to https://aws.amazon.com/

b. Click on Create a Free Account

c. You might be asked to enter credit card information. You will not be charged as long as you follow the instructions to use “Free tier eligible” services as you will see. d. Your phone number will be asked for to verify identity e. Select BASIC support plan f. After Signing Up, you should see the following page.

2. Creating a Linux Instance a. Sign in to aws.amazon.com(Under “My Account”, Click “AWS Management Console” b. You should see a console displayed like this

c. Under “Compute”, Click “EC2” d. On the following page, click “Launch Instance”

e. On Step 1, select “Amazon Linux AMI 2017.03.0 (HVM), SSD Volume Type - ami3883a55d” (the string 3883a55d after “ami” is dynamically generated by AWS)

f. On Step 2, select the Free-tier Eligible Instance Type

g. For Steps 3, 4, 5 go with the default Options and click Next h. On Step 6 “Configure Security Group”, click “Add Rule” and From the drop down menu choose “Type” as HTTP.

i. On Step 7, after clicking Launch a dialog box should pop up asking to create key pair.

j. Click Create Key Pair. k. Enter a name (e.g., IT276) for the new key pair in the Key pair name field of the Create Key Pair dialog box as shown above, and then click Download Key Pair.

The private key file “.pem” (e.g., IT276.pem) should be downloaded and should be saved in a safe place. Please remember the file location!

l. You can now click “Launch Instance” and then click again “view instances”.

m. You can now click “connect” to access your instance. You can either use Putty (a SSH client) from a Windows OS machine, or directly use “terminal” from a mac or Linux machine. A screen like below should assist you in connect with your VM

Save the DNS name of your Linux instance. E.g., ec2-52-15-67-53.us-east-2.compute.amazonaws.com

3. Getting into your VM a. Windows(Use Putty) i. Use this link to see how to use putty to connect to your instance http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/putty.html Once you log in, you should see the putty access window as below:

4. Traceroute a. From your Linux VM, enter the following command traceroute www.google.com b. You should get results similar to this

5. Running a Web Server from your VM a. b. c. d.

Make sure you’re connected to your instance Within your VM, type the following: Update instance by typing: sudo yum update –y Install the Apache Web server with PHP software: sudo yum install -y httpd24 php56 php56-mysqlnd

e. Start the web server: sudo service httpd start

f. You can test that your web server is properly installed and started by entering the public DNS name of your EC2 instance in the address bar of a web browser, for example: http://ec2-42-8-168-21.us-west-1.compute.amazonaws.com. If your web server is running, then you see the Apache test page

Part II What to hand in The goal of this lab is to introduce you to one cloud service AWS. The following questions will demonstrate that you’ve been able to get this lab done: 1. All screenshots (similar to the web page screenshots in this documents) demonstrate you have successfully created a Linux VM instance in AWS. 2. Show the DNS name of the created VM instance (e.g., ec2-52-15-67-53.us-east-2.compute.amazonaws.com)

3. A screenshot shows your successful SSH access to the VM instance. Type the command “date” and show the screenshot. (similar to the one below)

4. A screenshot shows the results of THREE times traceroute from the instance to google.com. What are the three RTTs of this test? Are these three RTT the same? Why?

Since traceroute sends in three signal packets in a single ping there are 3 RTTs(round trip time) for each ping. However, as can be seen from the screenshot above the RTTs are not the same for any pings at all. This is because RTTs also help us understand the consistency of the pings and also to check for any latency in the network transmission.

5. A screenshot shows the successful Web access to the web server in the instance. Please note, the DNS name as highlighted below should be clearly readable.
