1. Obtain the instance's public IP or public DNS. You can find this information in the EC2 console by selecting your instance and checking the "IPv4 Public IP" or "Public DNS (IPv4)" field.
2. Open your preferred terminal or command prompt and navigate to the directory where your private key pair file (.pem file) is located.
3. Set the permissions of the private key file to be accessible only by the owner. You can use the following command:

1

chmod 400 your-key-pair.pem

1. Connect to the EC2 instance using SSH with the following command, replacing your-key-pair.pem with the name of your private key file, and your-instance-public-ip with the public IP address or public DNS of your instance:

1

ssh -i your-key-pair.pem ec2-user@your-instance-public-ip

For Amazon Linux instances, the default username is ec2-user. If you are using a different Linux distribution (e.g., Ubuntu), use the appropriate username (ubuntu, centos, debian, etc.) instead of ec2-user.

1. When prompted, type 'yes' to confirm the connection and add the EC2 instance's fingerprint to your known hosts.
