Questions tagged [ssh-tunnel]

An SSH tunnel leverages the SSH protocol to transport unencrypted data through an encrypted connection.

An SSH (secure shell) tunnel provides a secure connection through which unencrypted data can be sent.

This technique can be useful for:
- Providing security for insecure network protocols.
- Hiding one's true location (ip).
- Circumventing blocked ports in firewalls.
