Connecting to an Instance

Users can access Qumulus instances through various platforms without any obstacles in their workflow. Whether you're using Windows, macOS, or Linux, you can connect to your instances to effectively manage cloud resources.

Prerequisites

• SSH Key Pair: Qumulus demands key pairs for all new instances during their creation process. Check that you possess an existing key pair ready for use. If you don't have one, Refer to the Qumulus documentation(link) for instructions on generating key pairs.

• Public IP Address or Hostname: Obtain your instance's public IP address or hostname.

Steps to Connect

1

Retrieve Connection Information

Navigate to Compute > Instances:

• View the instance list by logging into the Qumulus Cloud Platform dashboard

View Instance Details:

• You can find the public IP address or hostname required for connection by opening the Instance Summary by clicking the desired instance.

2

Prepare Your SSH Key Pair:

Verify Key Association:

• Ensure your instance has a proper association with the correct SSH key pair.

Secure Your Key:

• The private key created during setup should be downloaded and kept in a safe storage location. The secure connection depends heavily on this key for its establishment.

3

Connect to Your Instance

Select the method that matches your operating system.

1. For Windows Users:

1.1 Using MobaXterm:

1. Download and install MobaXterm.

2. Start by opening MobaXterm and navigate to Session >SSH.

3. Enter your public IP address or Hostname into the "Remote host" input field.

4. Click "OK" to initiate the connection.

1.2 Using Windows PowerShell:

1. Open PowerShell.

2. Access the directory where your private key file is stored.

3. Enter this command, substituting path\to\your_private_key.pem and username@instance_ip_address with your instance details:

ssh -i path\to\your_private_key.pem username@instance_ip_address

2. For macOS and Linux Users:

1. Open the Terminal application.​

2. Check that your private key file possesses appropriate access permissions.

chmod 400 /path/to/your_private_key.pem

1. Connect to your instance using SSH:​

ssh -i /path/to/your_private_key.pem username@instance_ip_address

Replace /path/to/your_private_key.pem with the exact path to your private key file, username with your instance's username, and instance_ip_address with your instance's public IP address or hostname.

Additional Considerations

Before you connect, please ensure the following:

• Security Groups and Firewalls: Security Groups and firewalls must allow inbound SSH on port 22 for your IP address to connect to your instance

• Username: Your Qumulus instance uses default usernames which depend on its operating system (e.g., ubuntu for Ubuntu).
