My website has been under extensive ddos attack for about a month now. I haven't paid much attention to it as it wasn't important but some other websites on the server started experiencing the same attack so I have moved them to another server with managed wordpress hosting (they offer ddos protection).
I have no way of finding out if the attacks have really been blocked or is it just the attacker taking a break.
I tried a DOS attack software and it seems to be blocked OK but the attack I was undergoing earlier was of a different nature (new IP with every single request but same use agent). My question is: how can I find a software that lets me emulate the ddos attack of the nature I have mentioned above. Here's a screenshot of my visitor log on old server:
