Logging in

Accessing the Cluster

• Cluster URL: hpc.cambercloud.com
• Login node access via: ssh user@hpc.cambercloud.com

SSH Key Setup

Option 1: Generate New Key Pair

1. Log in to the Camber Cloud web portal
2. Navigate to Profile > Security and Access > SSH Keys
3. Click “Generate New Key”
4. Download the private key file (.pem) immediately
   • Important: This is your only chance to download the private key
5. The public key is automatically registered with the cluster

Option 2: Use Existing Key Pair

1. Generate a key pair on your local machine if needed:

   # Using ED25519 (recommended):
   ssh-keygen -t ed25519
   
   # Or using RSA:
   ssh-keygen -t rsa
2. Log in to the web portal
3. Click “Add new key”
4. Enter a descriptive name
5. Copy and paste your public key contents (from *.pub file)

Connecting to the Cluster

# With a generated key from Option 1:
ssh -i /path/to/downloaded/private-key.pem user@hpc.cambercloud.com

# With existing key from Option 2:
ssh -i ~/.ssh/id_ed25519 user@hpc.cambercloud.com  # for ED25519
# or
ssh -i ~/.ssh/id_rsa user@hpc.cambercloud.com      # for RSA

Important Security Notes

• Keep your private key secure
• Only upload the public key to the portal
• Supported key formats: ssh-ed25519 and ssh-rsa
• If you lose your private key, generate a new key pair
