SSH Tunneling
SSH tunneling, also known as SSH port forwarding, is a method of securely transmitting network data through an encrypted SSH connection. It creates a secure tunnel between a local and remote machine, allowing users to forward traffic from one port to another, bypass firewalls, or access restricted services. This technique is commonly used for secure remote access, database connections, and web service proxying.
Developers should learn SSH tunneling when they need to securely access internal services (like databases, APIs, or web servers) from a remote location, bypass network restrictions, or encrypt unencrypted traffic. It's particularly useful for connecting to development environments, accessing production resources securely, or creating temporary secure channels for debugging and testing.
