Проблемы с SSH без пароля

Я пробовал настроить SSH без пароля для кластера MPI, над которым я работаю. Я генерирую ключ RSA на главном узле и отправляю открытый ключ моему клиентскому узлу. Он отправляет, но отказывается подключаться через открытый / закрытый ключи и возвращается к подключению с помощью пароля, когда я пытаюсь подключиться через SSH без пароля. Вот вывод из файлов отладки и журналов, любая помощь будет принята с благодарностью!

client /var/log/auth.log
