Connecting to a Linux Instance

You can connect to Linux Instances via SSH sessions using passwords (less secure) or SSH key pairs (most secure)

Connect from a Windows Machine​

To connect to your Linux Instance from a Windows machine, you will need to use a small application called PuTTy, an SSH client.

  1. Download and install PuTTy.

  2. Launch PuTTy on your computer.

  3. Enter your Instance’s IP address in the Host Name (or IP Address) field.

    Putty

  4. Navigate to Connection > SSH > Auth.

    Putty

  5. Click the Browse button and select the private key file that you had already generated.

  6. Click Open at the bottom of the screen to open a connection to the Instance. PuttY prompts you to allow the connection to the host.

  7. Click OK to confirm and the terminal window will be displayed.

  8. Enter the default root user name (typically ubuntu for Ubuntu images and root for all other Linux OS images) and press Enter to authenticate against the server with your SSH key.

You are now connected to your Instance.

Connect from a macOS or Linux Machine​

  1. Open any terminal program.

  2. Enter the following command below into the terminal.

    important

    Make sure you replace <your_private_key> with the filename of your private key; <your_instance_ip> with the IP address of your Instance; and <username> with the default root user name (typically ubuntu for Ubuntu images and root for all other Linux OS images).

    ssh -i ~/.ssh/<your_private_key> <username>@<your_instance_ip>

  3. If/when prompted, allow connection to the host by typing yes, then press Enter.

    The authenticity of host 'myhost.ext (212.47.206.34)' can't be established.  
    RSA key fingerprint is 4f:ba:65:cf:14:64:a7:1e:b6:07:7c:00:71:95:21:fa.
    Are you sure you want to continue connecting (yes/no)?

    You are now connected to your Instance.
