    1. Review your configuration under Summary and click Launch Instance.

    Screenshot 2023-09-27 at 10.12.01 AM.png

    Your instance will now start, which may take a moment. You will be shown the Launch Status page with the message Successfully initiated launch of instance.

    1. On the lower right of the page click on View all Instances to view the list of EC2 instances. Click on your instance. It will go through an initialization process. Once your instance has launched, you will see your Linux server as well as the Availability Zone the instance is in, and the publicly routable DNS name.

    SSH into an EC2 instance

    The operating system of your local computer determines the options that you have to connect from your local computer to your Linux instance. Here are directions to connect from Windows Using PuTTY or OpenSSH, From Linux & MacOS-X using ssh client and from Windows Subsystem for Linux (WSL) using ssh client.

    Note: The premade CHENLAB-PUBLIC AMI is Ubuntu, so your username will be “ubuntu”

    Connecting from Windows using PuTTY

    We will now use the private .ppk file of the key pair generated earlier to open a SSH session to the EC2 instance.

    1. Start the PuTTy application.

    2. Enter in the IP address of the EC2 instance in the Host Name (or IP address) field.

    3. To save the session (so we dont have to repeat the configuration everytime) provide a name in the Saved Sessions field.

    4. In the left navigation pane under Connections clickon SSH and next click on Auth.

    5. In the Private key file for authentication field click Browse and browse in the .ppk file downloaded when creating the key pair earlier.

    6. Next in the left navgation pane click on Session (scroll up if you need to) and and further click on Save to save the session.

    7. Next click on Open to start the SSH session.

    8. PuTTy will now attempt to start an SSH Session.

    NOTE: You will get a security Alert The Servers host key is not cached in the registry, click on Yes to continue.

    1. You will now be presented with the login as prompt.

    2. At the login as prompt type ec2-user if your image is Amazon Linux OS or ubuntu if your image is Ubuntu Linux OS and hit enter.

    You would have now logged into the EC2 instance on AWS.

    Connecting from Windows using MobaXterm

    We will use the private .pem key pair to open an SSH session to the EC2 instance.

    1. Start the MobaXterm application.

    2. To open a session, click on Session in the top-left corner, then click SSH.

    3. Enter in the IP address of the EC2 instance in the Host Name field.

    4. To the right, select username and enter your username for the session.

    NOTE: Username to be used here is ec2-user if your image is Amazon Linux OS and ubuntu if your image is Ubuntu Linux OS.

    1. Below, click on Advanced Settings, and select private key (use your .pem file).

    2. Click Ok.

    MobaXterm will have logged you in to your EC2 instance.

    Connecting from Windows using Windows Subsystem for Linux

    We will now use the private .pem file of the key pair generated earlier to open a SSH session to the EC2 instance.

    1. Copy the private key from Windows to WSL - In a WSL terminal window, copy the .pem file (for the key pair that you specified when you launched the instance) from Windows to WSL. Note the fully-qualified path to the .pem file on WSL to use when connecting to your instance.
    cp /mnt/<Windows drive letter>/path/my-key-pair.pem ~/WSL-path/my-key-pair.pem
    1. In a terminal window, use the ssh command to connect to the instance. You specify the path and file name of the private key (.pem), the user name for your instance, and the public DNS name or IP Address.

    NOTE: Username to be used here is ec2-user if your image is Amazon Linux OS and ubuntu if your image is Ubuntu Linux OS.

    sudo ssh -i /path/my-key-pair.pem ubuntu@<ip-address>

    you will see the following response

    The authenticity of host '<ip-address>'
can't be established.
RSA key fingerprint is 1f:51:ae:28:bf:89:e9:d8:1f:25:5d:37:2d:7d:b8:ca:9f:f5:f1:6f.
Are you sure you want to continue connecting (yes/no)?
    1. Enter Yes

    you will now be logged into the EC2 Instance.

    Connecting using SSH on Linux & MacOS and OpenSSH on Windows

    We will now use the private .pem file of the key pair generated earlier to open a SSH session to the EC2 instance.

    1. In a terminal window, use the ssh command to connect to the instance. You specify the path and file name of the private key (.pem), the user name for your instance, and the public DNS name or IP Address of your instance.

    NOTE: Username to be used here is ubuntu if your image is based on the Ubuntu Linux OS and ec2-user if your image is based on Amazon Linux OS. (See this page which covers many of the common AMI OSs.)

    ssh -i /path/my-key-pair.pem ubuntu@<ip-address>

    You see a response like the following:

    The authenticity of host 'ec2-198-51-100-1.compute-1.amazonaws.com (198-51-100-1)' can't be established.
ECDSA key fingerprint is l4UB/neBad9tvkgJf1QZWxheQmR59WgrgzEimCG6kZY.
Are you sure you want to continue connecting (yes/no)?
    1. Enter Yes

    You will now be logged into the Instance.

    NOTE: you might need to change the permissions of the key file by running the chmod command as follows. Edit to match your path and key pair name.

    sudo chmod 600 /path/my-key-pair.pem

    For detailed directions on these please have a look at the following links:

    PuTTY, Windows Susbsystem for Linux, MacOS-X ssh Client, Linux ssh client
