Accessing HPC Systems via SSH and VPN

High-performance computing (HPC) clusters offer immense computational power, but accessing them securely is the first and most critical step for any researcher or data scientist. This text-based course guides you through the foundational concepts and practical steps required to establish secure, remote connections to HPC environments from Linux, Windows, and macOS. You will transition from a beginner with no remote command-line experience to a confident user capable of managing secure keys and navigating remote terminal sessions safely. What you'll learn: - Understand foundational HPC architecture, network security zones, and remote access principles - Configure off-campus VPN client connections to safely reach secure academic and corporate clusters - Generate and manage SSH cryptographic key pairs across different operating systems - Establish passwordless SSH authentication to streamline your remote login workflow - Apply modern security best practices, including SSH config file optimization and multi-factor authentication concepts - Troubleshoot common connection, permission, and network timeout issues independently This course begins with essential networking definitions and security fundamentals before walking you through step-by-step configuration guides for terminal environments. You will read clear explanations, study configuration file examples, and practice setting up your own local SSH environment. This course is designed specifically for beginners, researchers, and students who are new to high-performance computing and remote server administration. No prior command-line experience is required.
