Я надеюсь, что не пропустил ответ, но пока кажется, что я бью кирпичную стену. Я использую VirtualBox на моем Mac OS X с гостевой системой Ubuntu 12.04. Хотя он отлично работает с аутентификацией по паролю, он не работает с ключами. Я просто не могу найти свою ошибку.
Я ценю любую помощь. Заранее спасибо!
Я получаю следующее:

До сих пор я сделал следующее:
0 post os install
$ adduser sshuser
1 backup config (remote host)
$ sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.backup
$ sudo chmod a-w /etc/ssh/sshd_config.backup
2. config (remote host)
$ sudo nano /etc/ssh/sshd_config

$ mkdir ~/.ssh
3. Generate and send keys (localhost)
if no .ssh dir:
$ mkdir ~/.ssh
$ chmod 700 ~/.ssh
$ ssh-keygen -t rsa -b 4096
$ ssh-add id_rsa
$ scp -P 3022 ~/.ssh/id_rsa.pub sshuser@localhost:/home/sshuser/.ssh/uploaded_key.pub
(remote host)
$ touch authorized_files
$ cat uploaded_key.pub >> authorized_files
$ chmod 600 authorized_files
$ sudo nano /etc/ssh/sshd_config
$ PasswordAuthentication no
$ sudo service ssh restart
(localhost)
$ ssh -p 3022 user@host
(where host = vboxeth ip 192.x.x.x)
