Это никогда не работало правильно, я не думаю. Я не могу вспомнить, просто вводил пароль все это время. Я управляю десятью серверами с балансировкой нагрузки, но я получаю к ним доступ через внутренний ip. Когда я ssh-copy-id мой ключ к удаленной системе, он выглядит, как будто он успешно аутентифицируется, но все равно запрашивает у меня пароль. Моя папка .ssh имеет perms 600, только known_hosts имеет 644, а другие серверы, на которых работают ключи, имеют такие же perms. /var /log /secure говорит, что это было принято. Все перми в /etc /ssh /* 644. Есть идеи? Заранее спасибо!
