AWS Permission denied (publickey)

Question

Я пытаюсь подключиться к своему экземпляру EC2 и получить следующую ошибку.

Command Я бегу: SSH -v -i key.pem убунту @ [мой экземпляр адрес]

Я изменил разрешения на файле ключа 600, как я видел в других потоках, но не решила проблему.

выход я получаю:

Answer 1

удалось решить путем редактирования/и т.д./ssh_config (на OSX) и добавив следующую строку:

ChallengeResponseAuthentication yes 

Answer 2

Обязательно проверьте:

1. SSH пары ключей файл

2. Имя пользователя. Например: root, ec2-user, ubuntu, ...

3. Имя хоста вашего сервера. Например, если вы остановите свой экземпляр, он получит новый IP-адрес.

Если вы используете Ubuntu Cloud Гостевая официальное изображение, вы можете проверить Ubuntu EC2 Starter's Guide.
