Не может заставить SSH работать

Я пытался настроить соединение SSH с помощью ключа RSA, но я не могу получить его работа. Мои полномочия в порядке, я установил в sshd_configfile, что он должен использовать открытый ключ для аутентификации, я, конечно, создал ключ и добавил его к ~/.ssh/authorized_keys.

Что не так? Я уже пытаюсь зафиксировать эту половину дня. Это - мой вывод, когда я пытаюсь соединиться:

Я уже перезапустил своего sshd демона и ssh сервис много, он не работал.

В моей системе мне пришлось открывать порты, используя gufw (графический интерфейс пользователя для несложного межсетевого экрана), также, если вы пытаетесь получить доступ к хосту из нелокальной сети, вам также потребуется настроить межсетевой экран вашей локальной сети, чтобы разрешить и направлять трафик. к конкретной машине и порту.

Напомним, что если вы планируете открыть свою локальную сеть для внешнего мира, не используйте порт 22, так как это порт по умолчанию для ssh, и он, вероятно, будет постоянно проверяться и подвергаться атакам.

Я использовал эту справку сообщества ubuntu.com SSH для помощи в настройке моей. но получил помощь настройки брандмауэра в другом месте. Надеюсь, это немного поможет.

Клиент SSH не очень помогает, когда что-то не так.

Я предлагаю вам SSH на сервер (я предполагаю, что у вас есть какой-то другой способ получить доступ к оболочке) и изучите /var/log/auth.log.

Если здесь нет полезной информации, попробуйте увеличить LogLevel в sshd_config до VERBOSE или DEBUG, а затем перезагрузите сервер SSH, используя sudo service ssh reload.
