• After saving and exiting restart sshd service

  sudo service ssh restart
  
          
          
  

• Query ip address

  
          
          
  ifconfig
  Or #
  ip addr show eth0
          
          
  

  Then this problem will not happen again, according to ip connection. The first time you connect the prompt will appear, whether to save the key, select Yes!

The connection is successful ???

• 保存并退出后重启sshd服务

  sudo service ssh restart
  
      
      
  

• 查询ip地址

  
      
      
  ifconfig
  # 或者
  ip addr show eth0
      
      
  

  然后根据ip连接就不会再出现此问题了。第一次连接会出现该提示，是否保存key，选择Yes！

连接成功了···
