Using plesk, impossible to connect to SSH

Lately for a client I managed his Plesk 9.5 server (Centos 5.4)

But impossible to connect it using SSH.

Of course I searched everywhere in the plesk panel :

Ok - SSH is enable for the domain administrator and so on

Finally I tried to restarted ssh using the schedule task.

Firstly don't forget to change in the properties the address to recieve the crontab message and Eureka I got :

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

Just make another schedule task to apply the good rights and restart sshd :

chown root:root /var/empty -R && /etc/init.d/sshd restart

And everything is fine now
