I am attemtping to SSH my home PC from another PC. Before I even get to the command line, I need to know my IP address. But I'm getting confused. If I use ifconfig, I get a a load of "inet" numbers for eth0. If I go onto any of the dozens of "test your IP" websites they all point to an address that is actually the address of my ISP. So what should I use when I want to use SSH?
I'm using Linux.
