Для тестов разработки мне нужно настроить SFTP-сервер. Поэтому я хочу знать, можно ли использовать одну и ту же машину в качестве клиента и сервера. Я пробовал и продолжаю получать эту ошибку:
> Permission denied (publickey).
> Connection closed
и запустив ssh -v agharroud@localhost я получил :

Есть идеи по поводу проблемы? Спасибо !
Да, это возможно и должно работать из коробки (если у вас есть ssh и sshd, что похоже на то, что вы делаете).
Не глядя на вашу конфигурацию, я бы предположил, что либо ваша аутентификация по паролю отключена, либо ваш закрытый ключ имеет неправильные разрешения. /home/agharroud/.ssh/id_rsa и /home/agharroud/.ssh/id_dsa должен иметь 600 разрешения, если они есть.
