你将/etc/ssh目录下的ssh_host*文件mv到别的目录,重新启动ssh服务,让他重新生成key,看看能登陆上不

也试过。。

1. 用fuser检查一下是否有其他进程占用/dev/tty；
2. 确认.ssh的目录是否是下面的权限；

drwx------. 2 root root 4096 Jun 17 21:17 .ssh

3. 检查端口22是否是LISTEN的状态，和iptable是否开放22端口：

# service iptables status | grep -i 22
4    ACCEPT     tcp  --  0.0.0.0/0            0.0.0.0/0           state NEW tcp dpt:22

do following:
/etc/init.d/xinetd stop

than SSH
if works, you xinetd config has problem

我觉得现在问题出在tty上。。。但新建了以后也不行啊
