在机器上直接登录，问题显示如下：

/var/empty/sshd must be owned by root and not group or world-writable.

问题：

Linux上的SSH无法启动

报告/var/empty/sshd must be owned by root and not group or world-writable.

解决办法：

首先通过物理终端进入到linux上，手工检查ssh发现没运行

-bash-2.05b# /etc/init.d/sshd status

sshd is stopped

手工启动服务，发现报告权限错误。

-bash-2.05b# /etc/init.d/sshd start

Starting sshd:/var/empty/sshd must be owned by root and not group or world-writable.

[FAILED]

-bash-2.05b#

使用rpm -V 命令可检查到ssh的软件包正常，但某个目录的属主错误。

-bash-2.05b# rpm -V openssh-server

S.5….. c /etc/ssh/sshd_config

…..U.. /var/empty/sshd

-bash-2.05b#

经查看发现这个目录的属主不是root，所以启动ssh报错

-bash-2.05b# ls -ld /var/empty/sshd/

d–x–x–x 2 vu00106 root 1024 Feb 2 2005 /var/empty/sshd/

-bash-2.05b#

修改为root属主，启动成功

-bash-2.05b# chown root /var/empty/sshd/

-bash-2.05b# /etc/init.d/sshd start

Starting sshd: [ OK ]

-bash-2.05b#

至此问题修复。

另外，还可以尝试：

这个是权限的问题

可采取以下两步解决

chown -R root.root /var/empty/sshd

chmod 744 /var/empty/sshd

service sshd restart
