Huh. Don't know what happened but now the command Code: cat ~/.ssh/id_urpo | ssh user@computer 'cat >> ~./ssh/authorized_keys/id_urpo' worked just fine. I guess I misspelled it. I have the id_urpo now on my MacBook Pro, now what?
cat ~/.ssh/id_urpo | ssh user@computer 'cat >> ~./ssh/authorized_keys/id_urpo'
If I try to browse from the N900 to find the original id_urpo, I can't find it, thanks to the fact that I can't browse to the /root.
