My friend has a little trouble getting around his new Linux system. I'm fairly knowledgeable in that topic so I want to SSH into his machine to take a look for myself.
Problem is he lives in a student hall, so he can't simply forward a port in the router. My idea was to create a Android WifiHotspot, connect his computer and forward port 22 to his local address. I tried that at home but none of the apps really work or want to do what I want (I don't want to SSH into my phone, I want to forward a port in my phone to a computer) and the questions asked to the topic are mostly 'opening ports for games' or 'SSH into my phone from my computer' but not really what I want. There us the app 'Port Forwarder' that seems to do what I want but it didn't really work. On the flip side, I couldn't even ping my phone, so there might be something more wrong.
Can someone help?
