紧急求助：ssh登录时提示permission denied please try again

noted2011

移植了一个openssh到自己板子上（arm板），结果登录时，总是报permission denied please try again的错误。按照网上的办法，尝试了好多，但还是没有解决，紧急求助大家帮忙解决一下，深表感谢！
说明几点：
用户名和密码都是root,不存在密码错误，因为就是用root 账户登录的，无法登录成功。
防火墙(iptables)没有开启。
sshd已经开启。
[root@OK2440  /root]# ps | grep sshd
  942 root      3812 S    /usr/local/sbin/sshd

按照网上的说法，修改/etc/ssh/sshd_config文件，设置如下：
PasswordAuthentication yes
PermitRootLogin yes
UsePrivilegeSeparation no
但仍然没有解决问题。
清除/root/.ssh/known_hosts(rm –f /root/.ssh/known_hosts)也不行。
更改root 账户密码，重启sshd。不报permission denied please try again，但是报Your password has expired. You must change your password now and login again!

192.168.0.15是我自己板子的ip地址，是可以ping通的。


实在找不到原因，急切等待答案，求大侠们帮忙解决一下这个小问题。

下面是我的具体操作。
