I am trying to set up an SSH tunnel into a small Lubuntu server that I have created, and I am unsure about how to actually find the IP address that I will use to connect to it from my laptop. The SSH service is 100% running on the server. I have total root access to the server, so I can find anything that I need.
I have found numerous resources online, but with all of them, as soon as I type "ssh USERNAME@IP_ADDRESS" (filling in the information obviously) the terminal just creates a blank new line and nothing happens past that, so I assume that I am using the wrong IP. The server is connected via Ethernet to a different network as my laptop is connected to via WiFi.
I have tried using the IP address from ifconfig, but that doesn't work. I have tried using the public ip address from "curl ipinfo.io/ip" and that didn't work either.
Any help would be appreciated.
