Description of my issue:

Hi Support,

One of my site has a big amount of visits, sometimes there is a robot or a stanger IP come to my site and visits dozens of times in 1 min. It makes site has a huge server overload like 20+ for several minutes. At that time, other visitors can not see the site and it shows 500 error.

Does AdminTools has function that can ban the IP which like visit site 10 tims in 1 minute?


Cheers,
Dennis

Hello Dennis,

No, Admin Tools doesn't have such a feature and, quite frankly, I don't think it should have. By the time Admin Tools gets the chance to run your server has already allocated a big chunk of RAM and spent significant amounts of CPU time. I'd recommend talking with your host about the possibility of implementing a flood protection system directly on the web server. For instance, the ever-popular and personal favourite mod_security2 Apache filter/firewall can be configure for flood protection. The OWASP ModSecurity Core Rule Set Project already has this feature baked into their rule set. Since you're using RackSpace, where each site is its own virtual server, I guess that this kind of implementation is perfectly possible as it won't affect any other customers.

Hi Nicholas,

Thank you for your suggestion.

Now I am using the dedicated server. I will ask them for help install mod_security2 Apache filter/firewall.

Cheers,
Dennis

On a dedicated server it's certainly possible :) In fact, I'd say it's absolutely advisable to have a fine tuned mod_security2 rule set. It's one of the basics I have in my security presentation.
