Step 1
We need a user account with sudo previlege. If you are using an ubuntu machine you can use ubuntu
You can also create a new user using https://violetstreamstechnology.blogspot.com/2020/10/how-to-create-new-user-in-ubuntu-18.html
For this lab we will use ubuntu user account. Please launch a target ec2 instance. ubuntu 16.04
Step 2:
Create a password for ubuntu
i. Login to the target ec2 machine
ii. Switch to root
sudo su
iii. Create password for ubuntu
passwd ubuntu
When prompted enter admin for the password
iv. Create password for
root user
passwd root
when prompted enter admin for the password
v. Make sure you enable password login Authentication:(skip this step if you have already done it)
