RAM is expensive on a VPS and many monitoring tools are memory hogs, but OSSEC's agents sound lightweight, so that's encouraging. I haven’t tried OSSEC.

I will then open up individually. i did it the other way around. instead of blocking and detecting the IP one at a time. i first block ALL countries IP, then allow only my country IP, if foreign IP is required.

A sudden large volume of registration attempts just almost brought my poor little server down. Initially I was blocking the IP addresses on my router (Fritzbox), but because this requires a reboot after every change, your method is much more helpful - at least till I find a method to do this on the router without the need for reboots Thank you for this great article.

Since memory is expensive on an VPS, this simple shell script is a lightweight solution.
