/Etc/init. d/sshd status
Sshd is stopped

Manually start the service and report permission errors.
/Etc/init. d/sshd start
Starting sshd:/var/empty/sshd must be owned by root and not group or world-writable.
[FAILED]

Run the rpm-V command to check that the ssh software package is normal, but the owner of a directory is incorrect.
Rpm-V openssh-server
S.5...... c/etc/ssh/sshd_config
... U.../var/empty/sshd

It is found that the owner of this directory is not root, so an error is reported when the ssh service is started.
Ls-ld/var/empty/sshd/
D -- x 2 vu00106 root 1024 Feb 2 2005/var/empty/sshd/
Changed to root owner. started successfully.
Chown root/var/empty/sshd/
/Etc/init. d/sshd start
Starting sshd: [OK]
