Don't understand these errors with logdrop target

[Steve Comfort <steve@4Dllc.com>]

Hi All,

Below is a snippet from my setup script :

        echo 1

        $IPTABLES -N LOGDROP
        $IPTABLES -A LOGDROP -j LOG --log-level debug
        $IPTABLES -A LOGDROP -j DROP

        echo 2

        $IPTABLES -P INPUT LOGDROP
       
        echo 3
       
        $IPTABLES -P OUTPUT LOGDROP
       
        echo 4
       
        $IPTABLES -P FORWARD LOGDROP

        echo 5

When this is run, I see the output below (the echo's are just to zone in 
on the exact rule(s) generating errors):

1
2
iptables: Bad policy name
3
iptables: Bad policy name
4
iptables: Bad policy name
5

The question is : Why does using LOGDROP as a policy cause these errors?

(I have CONFIG_IP_NF_TARGET_LOG set BTW).

Best regards
