Linux上的SSH无法启动

Linux上的SSH无法启动，
报告/var/empty/sshd must be owned by root and not group or world-writable

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。
