http://serverfault.com – iptables -A INPUT -p udp -m state --state NEW -m recent --set --name alimit --rsource iptables -A INPUT -p udp -m state --state NEW -m recent --update --seconds 1 --hitcount 5 --name alimit --rsource -j DROP it gives unknown error because cat /proc/net/ip_tables_matches udp tcp owner state length ttl tcpmss multiport multiport limit tos icmp Is there any alternative, since its disabled in my vps?
