Thanks all!

If you ban it using "csf -dr IP" , that IP never could login ssh, or httpd..

you can check it using: iptables -nL |grep IP

With that command, you will see that IP has been banned.

Thank for your reply!

Because many IP come from China try to login SSH, how can I only block the IP from China to login SSH? There are many different IP, I cannot only set the IP. Can I block it by country?
