AirPiConsole remote access with ZeroTier

In the previous post of this AirPiConsole series (part1, part2) I used Autossh to create a reverse tunnel from the device to a cloud VPS to permit remote access. The VPS I use is cheap but unreliable so the tunnel was down most of the time so I started looking for a better alternative. The solution came from the Packet Pushers podcast episode PQ134 about ZeroTier. What is ZeroTier?

AirPiConsole part two

Welcome back to AirPiConsole blog post, this is part two. If you read part one and followed the configuration steps you should now have a fully working Raspberry Pi Zero W connected to your WiFi network. You should also be able to connect via Bluetooth to get a console connection without knowing the IP address of the Raspi. Now it’s time to move on and start to actually connect to the serial ports.

AirPiConsole part one

As a network engineer I spend a lot of time with my laptop connected via serial cable to various devices. Physical serial connection is needed for initial device setup and sometimes per customer’s security policy I can’t access the network, so I can only use out-of-band management. I also configure many devices at staging lab that I call the “Theory room” because you know, in theory everything works ;-)
