First, sorry for my bad english. I’m spanish.
I need a similar system iptables for my private server. My PS works fine and correctly, but in some moments obtain too much HTTP requests per seconds and produce a DoS, too much zombie process (PHP5 [defunct]) and fall out server.
Actually, I block this requests with “deny from” in .htaccess, but this isn’t sufficient.
I need a similar system such as iptables, for block this requests without arrive to apache server, and avoid denial service.
