Automated script for IoT devices reverse SSH tunnels

[siliconhippy]

Nice explanation !

Now how would you configure to manage multiple Linux boxes ( NATed servers) from a single client running in a VPS via secure (SSH enabled) VNC?

Or which is the same, write an automated bash script to run automated reverse SSH script on each IoT device so the VPS remote server uniquely identifies each IoT device? Perhaps set up a port number pool on the remote server, and assign a port # to each incoming tunnel request ?

By that I mean multiple Linux boxes behind firewalls that can connect to a public IP server ( VPS.)

Can the keygen be done on the remote server, and the public key copied to each IoT device at install time, for simplicity and automation with no password?

I ask because most IoT devices become inaccessible after first “factory” configuration including say some bash scripts and VNC/reverse SSH install on each of these devices. Then we need to make sure these devices are accessible over the Internet remotely, but we should expect minimal intervention by IoT device users except boot and reboot and maybe typing in a username/ password at first boot setup.

What kind of simple script can we use on the IoT devices and remote server?
