SSH-соединение с сервером: «Permission denied (publickey)». [дубликат]

Я пытаюсь подключиться к удаленному серверу AWS (Ubuntu) с помощью SSH и получаю сообщение об ошибке:

Permission denied (publickey).

На моем локальном компьютере в разделе ~ /.ssh / config У меня есть этот набор:

Host someserver
    User potatouser
    HostName serverone.mysite.com
    Port 22

Host dashboard
    User potatouser
    HostName ec2-66-66-66-666.compute666.amazonaws.com
    IdentityFile ~/.ssh/dashboard
    Port 22

Запуск в терминале: ssh someserver работает нормально, запрашивает пароль и подключает меня.

Попытка подключиться ко второму серверу с закрытым ключом.

-rwx ------ 1 potatouser potatouser 955 13 февраля, 16:49 панель управления

-rwx ------ 1 potatouser potatouser 398 13 февраля 17:13 dashboard.pub

На моем AWS На сервере под моим пользователем ~ / .ssh / есть файл с именем: authorized_keys , внутри которого есть что-то похожее на открытый ключ, выглядит примерно так:

ssh-rsa asdasfagdsasfafsafadsfafs..... 
....
...

• Я попытался создать новый общедоступный файл на моем сервере с именем dashboard.pub (с тем же содержимым), если он следует за именем файла (?).
• Я попытался добавить в свой конфигурационный файл параметр: IdentitiesOnly yes , поскольку у меня есть несколько файлов ключей (id_rsa, ключи репозиториев git).
• Я попытался отредактировать файлы / etc / ssh / ssh_config и / etc / ssh / sshd_config , установив PasswordAuthentication на yes ( + sudo service ssh restart ).
• Вместо этого я попытался изменить HostName в моем файле конфигурации на IP.

Я заметил следующее:

Может быть, это потому, что он ищет файл приборной панели вместо dashboard.pub ?
