Ruby Net :: SSH :: AuthenticationFailed：用户root @ xxxxxxxxx的身份验证失败

Question

我试图通过Rails控制台SSH到另一台服务器，但是，得到以下错误。我几乎尝试了我在网上找到的所有建议，但仍然得到同样的错误。我可以用SSH登录服务器没有问题ssh [email protected]。

    Net::SSH.start("xxx.xx.xx.x","root",:keys=> ["ssh-rsa ........"], :verbose => Logger::DEBUG) do |ssh| 
       puts ssh
    end

好吧，所以它与库/键或SSH本身无关，我试图从gitlab-rails c这样做，它在同一台服务器上的irb工作正常。
