Device tunneling for beginners

In this guide, we will walk through the process of using Spacebridge for inbound communication with to your Hologram SIM. We will be using a Raspberry Pi in this example, but you can securely tunnel into any device that gives you port level access.

Creating a secure device tunnel

1. you'll want to make sure your end device has an open data session. Using a Raspberry Pi, you have a variety of choices on how to do that, for example ModemManager + NetworkManager, ChatScript, or the tool of your preference.
2. Follow the instructions in this guide. Note: if you have already uploaded your keys (required once), then only creating the tunnel is needed.
   
   
3. Once your tunnel is set up you can SSH into the device. In this case, it is a Raspberry Pi.
   
   
4. To close the tunnel, cancel the ssh command from the linked guide (ctrl+c).
