为什么启动iptables会出错!!!!

为什么启动iptables会出错!!!!

在/etc/sysconfig/目录下我有一个iptables,内容如下:
/sbin/iptables -A INPUT -s 172.16.68.22 -p icmp -j DROP

[root@qra-wls5 init.d]# ./iptables restart
Flushing all current rules and user defined chains: [  OK  ]
Clearing all current rules and user defined chains: [  OK  ]
Applying iptables firewall rules:
Bad argument `/sbin/iptables'
Try `iptables-restore -h' or 'iptables-restore --help' for more information.
[FAILED]
[root@qra-wls5 init.d]#

为什么会出错,多谢了!!!!!!!!
