iptable reports bad argument state

["J. Bakshi" <bakshi12 () gmail com>]

Dear list,

Here are some rules ( collected from net ) to prevent distributed ( from different machine) port scan.


``````````````````
IFACE=eth0
iptables -A INPUT -p tcp -i $IFACE -m state --state NEW -m recent --set
iptables -A INPUT -p tcp -i $IFACE -m state --state NEW -m recent \
--update --seconds 30 --hitcount   10 -j DROP
iptables -A FORWARD -p tcp -i $IFACE -m state --state NEW -m recent --set 
iptables -A FORWARD -p tcp -i $IFACE -m state --state NEW -m recent \
--update --seconds 30 --hitcoun  10 -j DROP
`````````````````````````````

But whenevr I insert these rules in my existing iptables rule it reports  "bad argument state"
The version of iptables is  1.4.4-2

Any clue ?
thanks
