Programmer [Security - Linux] Paying 50 USD for this job (PayPal)

[bolero]

I used this commands:

iptables -N conn-flood
iptables -I INPUT 1 -p tcp –syn -j conn-flood
iptables -A conn-flood -m limit –limit 7/s –limit-burst 20 -j RETURN
iptables -A conn-flood -j DROP
iptables -A INPUT -p icmp -m limit --limit 1/s --limit-burst 1 -j ACCEPT
iptables -A INPUT -p icmp -j DROP

I need write this command's already too?

iptables -I INPUT -p tcp -m state --state NEW,ESTABLISHED -m recent --set -j ACCEPT
iptables -I INPUT -p tcp -m state --state NEW -m recent --update --seconds 3 --hitcount 20 -j DROP

Or it's the same? x]

And after that, I have to restart something that? starts to work?
