Windows SSH Setup

The steps to enable both SSH and tunneling/port forwarding are as follows:

1. Open Settings > Update and Security > For Developers.
2. Click on the radio button for Developer mode; this will open up your system's port 22 and allow the SSH broker to start listening for incoming connections.
3. If you just switched to Developer mode, restart your computer, and then follow step 1 again.
4. Under Device discovery turn on the option labeled Make your device visible to USB connections and your local network.
5. Under Device discovery turn on the option labeled User OpenSSH (Beta) server for remote deployment.
