The SSH protocol provides secure remote login between machines. It supports connections to Gcore Virtual Machines running Linux. Two authentication methods are available:
  • With SSH keys
  • With a password
The second method is available only if a password was configured during VM creation using the initial setup options.
The VNC console in the Gcore Customer Portal provides an alternative browser-based connection method.

SSH connection steps

Complete the steps below in order. 1. SSH keys: Create a key pair — a public key stored in the Customer Portal and a private key stored locally. 2. (Optional) Key conversion: Convert SSH keys from .pem to .ppk format — applies only to PuTTY users (a separate SSH client for Windows; skip if connecting via terminal or Command Prompt). 3. Security group: Configure inbound and outbound rules to allow SSH connections on the instance. 4. SSH connection: Authenticate using the recommended method for the operating system.
