Cphulkd error

[Gagan]

Can Anyone let me know what is the meaning of following error:

Brute force detection active: 400 Unable to connect to database backend: Failed to connect to mysql db: cphulkd

Hello

This error message suggests that MySQL is not accessible. Are you able to verify if MySQL is running on this server? You can check this with a command such as:

mysqladmin processlist;

Also, if it's running, try running the following command to see if the database is corrupted:

mysqlcheck cphulkd

Thank you.

Actually we checked and mysql was down. Our server is Apache on CentOS. I checked on the internet for this and found that I should whitelist the MYsql DB ip in cphulk database. After doing this much again the server went down and we got the following error from logs:
Brute force detection active: 580 LOGIN DENIED - TOO MANY FAILURES - IP TEMP BANNED

What can be root cause ? and what does this error means ?

 

[cPanelMichael]

You should not have to whitelist the IP address of your server in cPHulkd. Were you able to get MySQL started again?

As far as cPHulk, it's normal for it to block brute force login attempts. More information on cPHulk is available at:

cPHulk Brute Force Protection - Documentation - cPanel Documentation

You may also find this document helpful if you want to manage it via the command line:

Thank you.

Both domains work but not on the cPanel ports.

 

[Gagan]

Till today morning both were working and we did not apply any new changes. How we can solve this issue ?

You might check your firewall to insure you've got the proper ports added. You can find the list here:
How to Configure Your Firewall for cPanel & WHM's Services - cPanel Knowledge Base - cPanel Documentation

 

[Gagan]

CSF firewall is enabled on our server and I have checked proper ports are added also. Please let me know what else I can do to make the Cpanels working ?

Following I am pasting from my server:

>>>>>

TCP_IN = "20,21,22,25,53,80,110,143,443,465,587,993,995,2077,2078,2079,2080,2082,2083,2086,2087,2095,2096"

# Allow outgoing TCP ports
TCP_OUT = "20,21,22,25,37,43,53,80,110,113,443,587,873,993,995,2086,2087,2089,2703"

# Allow incoming UDP ports
UDP_IN = "20,21,53"

# Allow outgoing UDP ports
# To allow outgoing traceroute add 33434:33523 to this list
UDP_OUT = "20,21,53,113,123,873,6277,24441"

Thanks.
