This lab is to configure the prompt of each VM with a new hostname and practice basic Linux commands and symmetric-key encryption and decryption. All the data needed for this lab is uploaded to the Dropbox as a ciphertext using AES. You need to decrypt the file to get the data. The key and IV used in the encryption of the data can be found in Step 2 of Task4.

Task 1: Configuring the prompt

For each VM, add the hostname to the prompt by following Slide 2-3 of Lecture2: Linux Basics.

Attach three screenshots of prompts of three VMs
