If you restart service SSHd and get this error:

#service sshd restart
#touch: cannot touch `/var/lock/subsys/sshd': No such file or directory

You can following this solution :-

1) Check if the directory /var/lock/ exists or may be /var/lock/subsys
If it is not exist then create it

2) Make permission 755 for /var/lock/subsys and restated sshd services

This Command Line

 mkdir /var/lock/subsys
 chmod 755 /var/lock/subsys
 /etc/rc.d/init.d/sshd start
 /etc/init.d/sshd restart
