Ключ SSH не работает

У меня проблема с ключами ssh на моем сервере. Всякий раз, когда я пытаюсь подключиться, он говорит мне об этом (я хочу использовать ключ для аутентификации себя, а не для ввода пароля, но он по-прежнему запрашивает пароль после.) Из моего понимания из других статей он запрашивает у меня мой пароль, потому что аутентификация секретного ключа или что-то еще? Я запустил ssh -vvv user@ip и получил следующее:

Мой конфигурационный файл в sshd_config:

  • Откройте дверь SSH для нокаутирующего друга
  • iptables: нет цепочки / цели / соответствия этим именем - добавление правила SSH ATTACK
  • Как загружаются SSH-ключи, на которые ссылается имя?
  • Как запустить плазменный стол с SSH-консоли на настольной сессии?
  • Неспособность блокировать грубую силу ssh с помощью iptables
  • Могу ли я выполнять команды из полуночного командного ssh-соединения?

UsePAM yes 

    Я пытался сделать что-то другое. Всякий раз, когда я отключил установленную pam passwordauthentication а pam – нет, он сообщает мне:

     $ ssh user@ip Enter passphrase for key '/home/Aericio/.ssh/id_ecdsa': Permission denied (publickey). 

    FYI: Я использую cygwin64 для использования ssh. Благодарю.

  • Исключения для управления ssh ControlMaster
  • Разрешить доступ через sshkey к определенному chrooted пользователю
  • Есть ли способ узнать, сколько ssh-подчиненных подключений открыто при подключении master ssh?
  • .ssh config file / IdentityFile проблема, какой ключ для копирования?
  • Команда ssh с кавычками
  • разрешение отклонено после команды ssh, даже если пароль правильный
  • One Solution collect form web for “Ключ SSH не работает”

    Это соответствующая часть вашего файла журнала:

     debug1: Trying private key: /home/Aericio/.ssh/id_ecdsa Enter passphrase for key '/home/Aericio/.ssh/id_ecdsa': debug3: sign_and_send_pubkey: ECDSA SHA256:/nMfW17zQ9zoH1UCzlSmLWtN4Mh/ST62SE5sB9B7D24 debug3: send packet: type 50 debug2: we sent a publickey packet, wait for reply debug3: receive packet: type 51 

    SSH нашел один ключевой файл (id_ecdsa) – он попросил вас пароль, а затем передал его на целевой сервер. Целевой сервер не доверял вашему ключу, и ssh перешел к использованию следующего метода проверки подлинности.

    Что вам нужно сделать, это скопировать открытый ключ на целевой сервер в файл authorized_keys , наиболее легко с чем-то вроде следующего:

     ssh-copy-id <user>@<destination server> 

    Если у вас есть более одного ключа или у вас есть одна конкретная личность для копирования, вы можете добавить -i .ssh/id_ecdsa.pub в команду
