无密码SSH不工作 – 密钥被复制并设置权限

我知道这个问题已经被问到，但我确定我已经做了所有其他答案的build议。

机器A：

使用keygen -t rsa创buildid_rsa.pub〜 / .ssh /
将机器A的id_rsa.pub复制到机器B用户的主目录
取得了id_rsa.pub 600的文件权限

机器B

将Machine A的pub key添加到authorised_keys和authorised_keys2：cat〜 / id_rsa.pub >>〜/ .ssh / authorised_keys2
做了id_rsa.pub 600的文件权限

我也确保了.ssh目录在A和B两台上都有权限700 。

如果我尝试从机器Alogin到机器B，系统会要求input密码，而不是ssh密码短语。

我有两台机器上的root用户使用无密码的ssh进行对话，但是我不能让一个普通的用户来这样做。

用户名必须是双方相同的？还是有一些其他的地方我错过了。

机器A是在Windows 7 PC上的VirtualBox内部运行的Ubuntu 10.04虚拟机，机器B是专用的Ubuntu 9.10服务器

更新：我已经运行ssh选项-vvv ，它提供了许多输出行，但这是最后几个命令：

使用ssh-copy-id复制你的密钥; 它会创build任何必要的文件/目录，并修复任何中断的权限。

文件名必须是： authorized_keys2 ，它应该是chmod 600 。

 ~/.ssh (700) ~/.ssh/authorized_keys2 (600) ~/.ssh/id_rsa (600) ~/.ssh/id_rsa.pub (644)

*更新* ：提供以下输出（来自远程服务器）：

 ls -ld ~/.ssh ~/.ssh/authorized_key*

SELinux是否启用？（使用： getenforce ），你得到Enfrocing或Enfrocing ？
