    I got 100 mails notification about failed login attempts to accounts.

    It didn't ban IP.

    Please check whether the IP is whitelisted in the server

    I am having the same problem, but thousands of attempts with no blocking. I am having to manually block.

    Not sure, but.....

    Am I reading this wrong or are these all within about 10/11 seconds time? It may take a little longer for the system to get the block in place?

    I have mine set to suspend people for 10 minutes after 5 login failures, but since the update I am seeing the same thing. I'll see 25 attempts in 2 minutes so it does not appear to be suspending them after 5 attempts, and I had one IP try over 100 attempts before I blocked it manually at the firewall. Anyone know what's up with cPHulk? It was working before the update, I wonder if something changed?

    We had the same problem and posted a ticket. The first class support team of cpanel solved the issue after a while and the fix will be included in next release according to them.
    The protection seems to work ok, but you get a message for each (or x number of ) attempts also after the IP is blocked.

    I too get this type of mails from cpanel. most of the attempt tries are from china and Indonesia. here are the ips for example

    67.23.139.33 Reverse DNS: vz2-33.netfirms.com (China)
    202.137.21.99 Reverse DNS: docsis1-99 (Indonesia)

    Hello,

    You can block the IP's using country code. The issue is that all the valid and invalid IP's of the countries specified in CSF will be blocked.

    In Firewall configuration (CSF), scroll down to CC_DENY and add the country code which you needs to block.

    Eg : Add CN for China in CC_DENY, that should block all IPs from China.
