To access the Linux virtual machine you will have to download the following software:
First, we need to convert the private key from the PEM format to the PPK format.
Open the PuttyGen software, access the Conversions menu and select the Import key.
After importing the PEM file, you need to set a password to protect your private key.
Click on the Save private key button to generate a file with the PPK extension.
In our example, a file named TEST.PPK was created.
Open the Putty software, select the SSH option and enter the username ubuntu@ followed by the IP address of the AWS virtual machine.
In our example, we used email@example.com.
Access the SSH authentication tab, click on the Browse button, locate the PPK file and click on the Open button.
An SSH connection will be started with your Ubuntu virtual machine.
Use the following command to become the root user on the Ubuntu virtual machine.
