ssh localhost: Permission denied (publickey) Ubuntu on WSL2

У меня проблемы с подключением к localhost и отказом в разрешении. Я пробовал все, от root или с помощью sudo.

У меня проблемы с подключением к localhost и отказом в разрешении. Я пробовал все от root или с помощью sudo.

Выполнил следующее:

ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
cat /root/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 0600 ~/.ssh/authorized_keys
ssh localhost

Как пользователь root я также сделал следующее на случай, если я использую любого пользователя, и каталоги перепутались:

cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys
cat /home/shervleradvm/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys

Первый раз было потому, что служба не работала. Итак, я выполнил sudo service ssh start
Я также отключил ufw для теста. sudo ufw disable
разрешения на чтение / запись для файлов ключей:

drwx------ 2 shervleradvm shervleradvm 4096 Nov 21 23:15 .
drwxr-xr-x 6 shervleradvm shervleradvm 4096 Nov 21 23:25 ..
-rw-r----- 1 shervleradvm shervleradvm 1146 Nov 21 23:23 authorized_keys
-r-------- 1 root         shervleradvm 2610 Nov 18 13:17 id_rsa
-r-------- 1 shervleradvm shervleradvm  577 Nov 18 13:17 id_rsa.pub
-rw-r--r-- 1 shervleradvm shervleradvm  444 Nov 18 15:05 known_hosts

В файле sshd_config отсутствует следующее, поэтому я добавил и протестировал каждое из них и их комбинации:

• AllowUsers: добавлено shervleradvm
• AuthorizedKeysFile: добавлено ~ / .ssh / authorized_keys /root/.ssh/authorized_keys

Затем я немного изменил свой конфигурационный файл после прочтения Пожалуйста, объясните полные шаги, необходимые для установки сервера OpenSSH на Ubuntu , так что теперь он выглядит например:

 # $ OpenBSD: sshd_config, v 1.103 2018/04/09 20:41:22 tj Exp $

 # Это общесистемный файл конфигурации sshd-сервера.  Видеть
 # sshd_config (5) для получения дополнительной информации.

 # Этот sshd был скомпилирован с PATH = / usr / bin: / bin: / usr / sbin: / sbin

 # Стратегия, используемая для параметров в sshd_config по умолчанию, поставляемом с

 # возможно, но оставьте их прокомментированными.  Опции без комментариев имеют приоритет над

Я не уверен, что еще я могу попробовать. Я застревал на этом несколько дней, и я прочитал все другие вопросы, касающиеся ssh.

ОБНОВЛЕНИЕ 3 :

Я только что попробовал ssh -i id_rsa localhost из каталога ~ / .ssh пользователя shervleradvm, чтобы попытаться определить private_key использовать. Это не сработало. Итак, я сделал touch config && vim config , затем определил закрытый ключ для localhost:

Host localhost
        HostName localhost
        User shervleradvm
        IdentityFile ~/.ssh/id_rsa

и затем запустил ssh localhost . Ошибка сохраняется.

ОБНОВЛЕНИЕ 4 : Я изменил владельца закрытого ключа на shervleradvm и дал следующие разрешения:

-rw------- 1 shervleradvm shervleradvm 2610 Nov 18 13:17 id_rsa
-r-------- 1 shervleradvm shervleradvm  577 Nov 18 13:17 id_rsa.pub

не помогло.
