Understand SSH

SSH is a required tool for anyone looking to interact with their cloud instances and services securely. By understanding and utilizing SSH, you can ensure that your interactions with the cloud are secure, reliable, and efficient.

What is SSH?

SSH (Secure Shell) is a network protocol that enables secure communication between a client and a server over an unsecured network. It is widely used for remote administration of systems and for securely transferring files.

Key features of SSH

  • Encryption: SSH encrypts all data exchanged between the client and the server, ensuring that sensitive information remains confidential and protected from eavesdropping.

  • Authentication: SSH supports various authentication methods, including password-based authentication and public key authentication, which provides an additional layer of security.

  • Integrity: SSH uses cryptographic hash functions to ensure the integrity of the data transmitted, preventing tampering and unauthorized modifications.

  • Port forwarding: SSH can forward network ports, allowing for secure tunneling of network connections and services.

Using SSH in Rumble Cloud

  • Access instances: SSH is used to access and manage virtual machines (instances) in the Rumble Cloud. You can connect to your instances via SSH to perform administrative tasks, install software, and configure settings.

  • Key pair management: You can create and manage SSH key pairs in Rumble Cloud. A key pair consists of a public key and a private key. The public key is added to the instance, while the private key is kept secure on the user's local machine.

  • Transferring files: SSH can be used in conjunction with SCP (Secure Copy Protocol) or SFTP (SSH File Transfer Protocol) to securely transfer files between your local machine and instances in the cloud.

Tips for using SSH

  • Use key-based authentication: Instead of using passwords, opt for key-based authentication for added security.

  • Protect private keys: Keep your private keys secure and set appropriate file permissions to prevent unauthorized access.

  • Regularly update SSH: Ensure that your SSH client and server are up-to-date with the latest security patches and features.

  • Limit access: Use security groups and firewalls to restrict SSH access to your instances from trusted IP addresses only.
