How to Use SSH on AWS

Secure Shell (SSH) is a network protocol that enables secure communication between two networked devices. When it comes to Amazon Web Services (AWS), SSH is an essential tool for managing your EC2 instances. In this article, we will discuss how to use SSH on AWS and connect to your EC2 instances securely.

Before we get started with SSH on AWS, you'll need to have a few things in place:

  • An AWS account with access to EC2 instances.
  • A running EC2 instance that you want to connect to.
  • A public key associated with your AWS account.

Step 1: Generate a Public/Private Key Pair

The first step in using SSH on AWS is to generate a public/private key pair. You can do this using the ssh-keygen command on your local machine. Open a terminal window and type the following command:
ssh-keygen -t rsa
This will generate a public/private key pair and save it to your home directory under the .ssh directory.

Step 2: Add Your Public Key to AWS

Once you have generated your key pair, you need to add your public key to AWS. To do this, navigate to the EC2 dashboard in the AWS Management Console and select "Key Pairs" from the left-hand menu. Click on the "Create Key Pair" button and give your key a name. Then, paste your public key into the "Public Key" field and click "Create."

Step 3: Connect to Your EC2 Instance

Now that you have your public key added to AWS, you can use SSH to connect to your EC2 instance. Open a terminal window and type the following command:
ssh -i /path/to/private/key.pem username@ec2-instance-ip
Replace /path/to/private/key.pem with the path to your private key file, username with the username of the user you want to log in as, and ec2-instance-ip with the IP address of your EC2 instance.

Step 4: Use SSH for Other Tasks

SSH can also be used for other tasks on AWS, such as transferring files between your local machine and your EC2 instance. To transfer a file from your local machine to your EC2 instance, use the following command:
scp -i /path/to/private/key.pem /path/to/local/file username@ec2-instance-ip:/path/to/remote/directory
To transfer a file from your EC2 instance to your local machine, use the following command:
scp -i /path/to/private/key.pem username@ec2-instance-ip:/path/to/remote/file /path/to/local/directory

SSH is a powerful tool for managing your EC2 instances on AWS. By following the steps outlined in this article, you can use SSH to connect to your EC2 instances securely and perform various tasks. Remember to always use best practices when using SSH, such as disabling password authentication and keeping your private key secure.
