target host

• Since no host trust relationships have been formed , the first time you ssh into a new host , you will be prompted with a message saying that the authenticity of the target host cannot be established , and you will be asked if you would like to continue
  由于还没有形成信任关系，在第一次ssh到一个新主机时，您将看到一条提示消息，告诉您不能建立目标主机的认证，并且被询问是否要继续。
