I'm using cloudflare with my litespeed installation and have been getting hit with a DDOS lately. I have the server setup so that it only allows 7 dynamic requests from a user per second. My logs show a number of ips requesting the same file several times a second (over 10). I suspect since I'm using cloudflare and have those IP's whitelisted, that the DDOS ips aren't being blocked. In addition, is there a way to block IPs without going through the interface, such as using a ssh command?
