DDOS Check !

A quick and usefull command for checking if a server is
under ddos is:

netstat -anp |grep 'tcp\|udp' | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n

cPanel/WHM cannot be accessed using IP/whm and IP/cpanel

The reason for this issue due to missing some lines in httpd.conf.


1) Open the apache configuration file(httpd.conf) in your favorite editor.

2) Add the following lines in the httpd.conf.

3) Now restart the httpd service in the server.

WHM locked out – cphulkd

cPHulk Brute Force Protection prevents malicious forces from trying to access your server’s services by guessing the login password for that service. BUT sometimes it becomes troublesome when you are accessing the cPanel with incorrect password and cPanel assuming you as attacker blocks you with below message :

This account is currently locked out because a brute force attempt was detected. Please wait 10 minutes and try again. Attempting to login again will only increase this delay. If you frequently experience this problem, we recommend having your username changed to something less generic.

To get out of such situation you can disable cphulkd protection :

login via ssh and disable cphulkd using the command below.

# /usr/local/cpanel/bin/cphulk_pam_ctl –disable

This should allow you to login to WHM and double check your cphulk settings.

You can view IP addresses that have been blocked via the WHM interface: WHM -> Security -> Security Center -> cPHulk Brute Force Protection in the Brutes table. On that screen, you can also customize brute force protection settings.

Flush DB will remove all blocked IPs:

WHM >>  Security Center >> cPHulk Brute Force Protection >> Click on Flush DB

Well the other way to this is to remove the IP’s blocked by cPHulk from its database .

ssh to the server login as root and type the following at the prompt

[root@server:] mysql

mysql> use cphulkd;

mysql>BACKUP TABLE  brutes TO ‘/path/to/backup/directory’;

mysql> SELECT * FROM brutes WHERE `IP`=’xxx.xxx.xxx.xxx’;

mysql> DELETE FROM brutes WHERE `IP`=’xxx.xxx.xxx.xxx’;
