You have a small network at home that is connected to the internet. On your home network, you have a server with the IP address of 192.168.55.199/16. You have a single public address that is shared by all hosts on your private network. You want to configure the server as a web server and allow Internet hosts to contact the server to browse a personal Web site. What should you use to allow access?

Learning Objectives

After successfully completing this assignment, students will be able to:

  • Configure, run, and test a linux server in AWS' EC2
  • Configure, run, and test a Windows server in AWS' EC2
Requirements
  1. Create an Ubuntu 20 LAMP server in EC2 like we did in class.
  2. Verify your that Apache was installed by opening your browser and enter the public dns of your server in the address bar. If it does not connect either you did not add HTTP to the Security Group, or the install did not work properly. Take a screenshot and save it (for submission below).
  3. The default location of html and php files is /var/www/html. Change to that directory. Now, using your favorite text editor use sudo to run your editor and create a file in that directory named info.php. For example, sudo nano info.php Then enter the following in that file to show information about the PHP installation: <?php phpinfo(); ?> Save the changes to the file and exit the editor.
  4. Now in your browser, enter the public dns of your server in the address bar / info.php. For example, my public dns was ec2-54-89-230-235.compute-1.amazonaws.com, so I enter  as the url. Take a screenshot and save it (for submission below).
  5. Create a Windows 2016 Server, like we did in class.  
  6. Login to it using Remote Desktop.  Take a screenshot of Remote Desktop connected to your Windows Server and save it (for submission below).
Clean Up

Now that you have completed the assignment, stop or terminate your EC2 instances. Stopping them means that it is now longer running, but your data is saved. That means you will not accrue charges on your running server. Terminating will both stop and delete the instances (also not accruing charges).

What to Submit
  • Screenshot of Apache page on your server shown in your browser
  • Screenshot of the PHP info page on your server shown in your browser
  • Screenshot of Remote Desktop session to your Windows Server

29. Recall that some IP addresses are reserved for private use (e.g., in a home, small business, or portions of a larger network). An example are addresses 10.0.0.0 to 10.255.255.255, used for private networks. All IP packets have a source IP address and a destination IP address. Then a Network Address Translation (NAT) is used so that a) Packets passing from private network to public network have their destination addresses modified. b) Typically packets passing from the private network to the public network have their source addresses modified while packets passing from the public network back to the private network have their destination addresses modified. x c) Packets passing from public network to private network have their source addresses modified. d) Typically packets exchanged between private and public networks have both their source and destination addresses unchanged. e) All of the above

Hi. You should write a Java program to meet the specification shown below. 

In this game(dice poker), the computer rolls two standard six-sided dice and you bet on the outcome. The outcome is the configuration of the numbers rolled (explanation below). The input/output should utilise a graphical user interface (input and message boxes).

 

1.1 Game flow

You start with some money in your bank. You play a number of rounds, where for each round you place a bet and the computer rolls the dice, checks results and modifies your bank balance. After certain conditions, the game ends and you're presented with some final information shown as a message box.

 

1.2 Placing bets

Before the computer rolls the dice, you can bet some money from your bank.

ˆ If the numbers are sequential (e.g. 1 and 2, 5 and 4, etc. Not 6 and 1), you earn double your bet.

ˆ If the numbers are identical (rolling doubles), you earn triple your bet.

ˆ Otherwise, you win nothing therefore you lose the amount of money you bet.

Before placing a bet, the computer should inform you of your current bank balance.

 

1.3 Starting Game- Game rules

When the game starts you are given £6 in your bank. Each bet costs £1 and you are allowed to make up to five bets before the game ends. The game will end if you run out of money, or you have no more attempts left (you made all five bets). At the end of the game, you will be told which of these conditions has ended the game.

 

1.4 Results display

Once the game has finished (all bets have been placed or you ran out of money) the computer will collate and display the results in a single message box, comprised by:

ˆ On row per bet, displaying your bet, the numbers rolled, the amount of money earned or lost for that bet.

ˆ One row at the end, displaying the amount of money that you have remaining in your bank at the end of the game.

 

1.5..Variable bet amount

Allow the user to change how much they would like to bet and change the amount you win accordingly. Allow bets between £1 and 4£ (integers only)

 

1.6.High score table

Create a high score table. The more money you have remaining in your bank at the end of the game the higher up the table you will be. In order to implement this, players will have to enter their name before they play. The high score table should be displayed as a separate message box after the results have been displayed at the end of the game(1.4)

Not1: Please use JoptionPane class instead of scanner class. 

Not2: Also If possible explain the description of your classes: what each does and how they relate to each other. And if possible, program should be extensible. E.g. Is it easy to change the number of dice? The number of rounds to play? The sides of the dice?Etc.
