[I]My problem is that, when I then try to ssh into n900 over the open reverse tunnel from an xp command prompt using: Code: ssh -p 19999 user@localhost my rsa key is being ignored and I get prompted for user@localhost's password - which I can't supply as there isn't one (but that's not the point, I don't understand why I'm even being asked for a password whren it should be authorising me via the authorized_keys entry).
ssh -p 19999 user@localhost
