Hi, I want to know how the limit match works. When we are trying to restrict the number of packets sent by a particular IP to, say, 3 / hour, we use a iptable rule like iptables -A INPUT -s 127.0.0.1 -m limit --limit-burst 5 I want to know how and where the count is stored. Are they checked for previous entries using netfilter log? Also, Can you please tell me the .c file in the netfilter source code which deals with handling various match and target extensions. If you can send me a link to any tutorial that deals with linux network programming then that will be great.
