The SSH protocol is a method for secure remote login from one server to another. You can use SSH to connect to Gcore Virtual Machines running Linux. The connection can be established in two ways: 1. With SSH keys 2. With keys and a password The second option is available only if you set up a password while creating your VM. Learn how to set up a password for Linux in our guide about customizing the initial setup of your VM.
InfoIf you want to connect to your VM via the Gcore Customer Portal, follow the instructions in our guide about connecting to a VM.

Steps to establish an SSH connection

1. Configure and manage SSH keys: Create and set up a pair of keys: a public key stored in the Gcore Customer Portal and a private key stored in your local storage. 2. (Optional). Convert your keys to .ppk format: If you generated SSH keys via PuTTY, convert the keys to the supported .ppk format. 3. Configure firewall settings: Set up the necessary protocols in firewall settings to allow outgoing and incoming connections to an instance. 4. Establish an SSH connection with an instance: Authenticate a VM using the recommended method for your operating system.
