secureCRT连接服务器报错：Unable to authenticate

用secureCRT连接远程服务器时报错：

1 The client has disconnected from the server.Reason:
2 Unable to authenticate using any of the configured authentication methods.

把key粘贴到其他用户是可以登陆的，说明本身key不存在问题，但是一直报错用户名或者key错误

登陆服务器查看auth.log

1 cat auth.log

解决办法：chmod 600  /home/user/.ssh/authorized_keys
