解决Generating SSH1 RSA host key: [FAILED]

出现这个错误的原因是没有权限,

su - root

输入密码.
重新执行:

/etc/init.d/sshd start
Generating SSH1 RSA host key:                              [  OK  ]
Generating SSH2 RSA host key:                              [  OK  ]

Starting sshd:                                             [  OK  ]
