Проблема с общими ключами SSH
Я установил аутентификацию по ключу паба между двумя серверами. Все должно работать, но меня все еще спрашивают пароль.
Вот части моего конфигурационного файла sshd, который я не изменил после настройки системы.
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile %h/.ssh/authorized_keys
Авторизованный ключевой файл существует и все. Я делал эту процедуру с открытыми ключами на многих машинах и никогда не было этой проблемы. Что бы вы предложили сделать?
Отладочный вывод дает мне следующее:

Изменить: мой файл закрытого ключа выглядит примерно так:
-----BEGIN RSA PRIVATE KEY-----
key goes here
-----END RSA PRIVATE KEY-----
Я сгенерировал его с помощью ssh-keygen -t rsa . Мои версии клиента и сервера:
OpenSSH_4.7p1 Debian-8ubuntu1.2, OpenSSL 0.9.8g 19 Oct 2007 (client)
OpenSSH_5.1p1 Debian-5, OpenSSL 0.9.8g 19 Oct 2007 (server)
Это структура каталогов на клиенте:
root@xxx:~/.ssh# ls -lha
total 20K
drwx------ 2 root root 4.0K 2010-10-19 18:00 .
drwxr-xr-x 8 root root 4.0K 2010-10-17 00:01 ..

-rw-r--r-- 1 root root 1.6K 2010-10-19 18:02 known_hosts
И это на сервере:
