So I have this GCP setup with IoT devices, but I want to SSH into devices that are geographically very far. Of course they are not on the same local network. My current idea is that I host a VPN and connect them through it while I am myself a client of this VPN. It works when I use a single device, however the autologin file (openvn.conf, user-locked) seems to only allow one connection and disconnect any other devices. Maybe I am misunderstanding how a VPN works, but how would one go about creating a new user automatically ? Is there anyway to have an autologin file that handles multiple devices ?

I am using OpenVPN Access Server v2.7.5 with a Debian Linux distribution on the devices.

Thanks in advance.

  • I don't know anything about OpenVPN, but VPN's in general usually allow only a single session per user account. Why not use an explicit user account for each device? You could use the device serial number, or some other unique identifier, as the username. – joeqwerty Feb 20 '20 at 17:52
  • Yes, but then how do I automate this user process ? These devices are built and configured at a third party so I don't have access to it before they are shipped unfortunately. – Charles Smith Feb 20 '20 at 17:57
  • If you don't have access to them how are you configuring them now? Are they preconfigured? If so, how about changing the "build" or configuration process? – joeqwerty Feb 20 '20 at 17:59
  • Currently I use the web interface on the go. I could go and check if OpenVPN as an API however. I am more wondering if VPN servers have mechanisms for this kind of use case. – Charles Smith Feb 20 '20 at 18:03
