Question

我正在尝试通过Rails控制台SSH到另一台服务器，但是，出现以下错误。我几乎可以尝试所有可以在网上找到但仍然遇到相同错误的建议。我可以使用SSH顺利登录ssh root@xxx.x.xxx.x服务器。

    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/密钥或def update(self, surface) self.data=surface.get_buffer().raw self.image=QtGui.QImage(self.data,w,h,QtGui.QImage.Format_RGB32)本身无关，我正在尝试从SSH进行此操作，在同一服务器上从gitlab-rails c可以正常工作。
