ssh-tunneling

To set up local port forwarding in Go, you establish an SSH connection and map a local port to a remote destination using provided code patterns. This Skill supplies the structural logic for tunneling data safely through the configured port.

SSH key authentication with passphrases in Go requires loading the encrypted private key and supplying the passphrase to decrypt it. The provided patterns configure client options to safely verify host keys during the connection handshake.

Parsing SSH config files in Go extracts host configurations and tunnel parameters to reproduce them in code. This approach dynamically loads connection settings, port forwarding rules, and key paths directly from standard SSH config syntax.

Implementing automatic reconnection for SSH tunnels in Go uses exponential backoff logic to retry failed connections. Keep-alive pings maintain the active session, ensuring the tunnel persists and recovers from network interruptions automatically.

Safe host key verification in Go validates the server's public key against known hosts before establishing the SSH connection. This process prevents unauthorized access by ensuring the remote server matches the expected cryptographic identity.
