KompЯ чувствую себя довольно глупо, спрашивая об этом, но я работаю над этим уже пару дней (время от времени), и я не могу понять это. Я только что установил lubuntu на моей машине, и я могу ssh локально на него с помощью localhost и аутентификации по паролю, и я могу пинговать его с двух других машин отлично. Я пытаюсь ssh с любой из этих машин, и он продолжает не аутентифицироваться с моим паролем.
я переустановил openssh-server пару раз, и я просто не могу показаться понять это.
есть ли у кого-нибудь предложение о том, что проблема может быть?
Новая Информация:
Я создал нового пользователя, чтобы убедиться, что он не был связан с пользователем, и новый пользователь не мог войти в систему.

затем я скопировал обратно sshd_config.заводские настройки по умолчанию для sshd_config и имел те же проблемы его не принимает мой пароль.
обновление:
Я сдался. Казалось, что это была какая-то проблема с lubuntu, но это было, вероятно, что-то странное, что я сделал. Вместо этого я установил linux-mint, и все работало безупречно. Кто знает... Мне очень нравится хотя linux-mint!
