Dear Sir: I'm new to network security and this is my first time to use iptables, when I run a firewall script, I got the following error: + /sbin/iptables -A INPUT -m limit --limit 3/minute --limit-burst 3 -j LOG --log-level DEBUG --log-prefix 'IPT INPUT packet died: ' iptables: Invalid argument I also tried -m owner option, it give me same error: "iptables: Invalid argument". But I don't get error for -m state. I can use iptables -L to see other rules except the error commands. I have the follow modules listed when I run lsmod: ipt_owner 3976 0 ipt_MASQUERADE 4960 1 ipt_REJECT 8520 1 ipt_state 2688 4 ipt_limit 3488 0 ipt_LOG 8288 0 iptable_nat 35162 2 ipt_MASQUERADE iptable_mangle 5248 0 ip_conntrack 62332 3 ipt_MASQUERADE,ipt_state,iptable_nat iptable_filter 4888 1 ip_tables 25088 9 ipt_owner,ipt_MASQUERADE,ipt_REJECT,ipt_state,ipt_limit,ipt_LOG,iptable_ nat,iptable_mangle,iptable_filter Can anyone help me how to solve the error? Thanks in advance, Susan
