ssh密钥认证排错

sshd配置文件没问题；

目录权限设置也没问题；

但是 ssh -vvv 提示：

debug3: no such identity: /Users/user/.ssh/id_rsa,/Users/user/.ssh/id_dsa: No such file or directory

之后查看，auth.log发现：

sshd[18063]: Authentication refused: bad ownership or modes for file /root/.ssh/authorized_keys

查看authorized_keys的owner不对，修改即可。
