I have a Mac running Lion at home. I disabled password ssh login; I just want to use public key.
I generated private/public key pair, but now I'm confused. I start a new job tomorrow, and want to login to my home machine from work. Every guide I see says "first copy the (local) public key to the (server) ... using a password."
But how do I do that from a new location if I've disabled password login?
Is there some way to access my home machine from anywhere if I take one of the keys with me?
I thought that if I just copy the home-machine public key into home machine 'authorized_keys', and then use the home-machine private key from my laptop, it would work...
