Hi all, I'm working on a project and I'm trying to figure out a way to have my device phone home and open up a terminal when connected to the internet. I'm unsure as to how to go about this properly. I've looked into AutoSSH but it doesn't seem like exactly what I need (I could be wrong here). Thanks in advance.

Have you looked into using a tertiary server that you could have a home computer connected to and SSH into that?

i.e. Have home server A connect to a cloud server B on a cron interval. Then have your device (when mobile) connect to server B. While on server B, ssh -p [port] where port is the current port that server A is ssh'd on.

wait open a terminal on your computer at home as soon as it's on the internet?

if so, use this

Code

@echo off
:here
if not %ERRORLEVEL%==0 goto terminal
::this will keep loopning until its connected to the internet
goto here

:terminal
::okay so lets say it has connected to the internet, it should start your terminal now
::idk which terminal you use, so i'll use Putty as example?
echo Device is connected to the internet
start C:\Program^ Files\PuTTY\putty.exe
pause & exit

I think this is what you're looking for?

What device are you using to "phone home", E.T.?

I'm an idiot for leaving out something that important. Device is a Pi 3.

Well the plan was to have the Pi 3 phone to a permanent home server and use it as an intermediary. However I didn't know that you can forward through the tertiary server like that. I looked up as much as I could during my research but apparently I didn't research well enough. I'm going to give that a try. And I'll report back.

Did you every get this successfully working? This is basically a reverse tunnel over a tertiary server and is used a lot in practice in security and system administration.
