Отказано в доступе, когда я пытаюсь SSH на сервер


0

У меня проблема, когда я пытаюсь подключиться к моему серверу с помощью закрытого ключа RSA. Я получаю ошибку «Отказано в доступе», за которой следует «Слишком много ошибок аутентификации для [пользователя]».

Примечание. Ключ rsa id_linux имеет разрешения 600.

Вот вывод оболочки:

Вот как выглядит мой файл ssh_config.

Host comics
    HostName [site]
    IdentityFile ~/Desktop/Storage/id_linux
    IdentitiesOnly yes
    PubkeyAuthentication yes
    User [user]
    Port 2222

Я пытался создать новый ключ, но это не сработало. У меня все еще та же проблема.

Спасибо за вашу помощь!

РЕДАКТИРОВАТЬ: Вот ключевой заголовок.

-----BEGIN RSA PRIVATE KEY-----
Proc-Type: 4,ENCRYPTED
DEK-Info: DES-EDE3-CBC,A9C39F2105CA158B

EDIT2: Вот вывод комиксов ssh -vvv. Примечание: я использую putty для доступа к Linux-машине, с которой я работаю. Кроме того, я создал новый ключ, чтобы убедиться, что я использовал правильную фразу-пароль.

ты скопировал свой id_linux.pub в ~/.ssh/authorized_keys файл на целевом хосте?
Serge

Что /home/ryan/Desktop/Storage/id_linux (Заголовок)? Разве это не замазка формата ключа? - Якудже вчера
Jakuje

@Serge Ключ был создан на целевом хосте и скопирован на компьютер, который я использую.
nryan

@Jakuje Я разместил заголовок моего ключевого файла.
nryan

Ты не ответил на мой вопрос. Что у вас есть в файле ~/.ssh/authorized_keys на хосте вы подключаетесь?
