If the IP is already dedicated to a domain/account you will have to first SSH to the server.

Then you want to edit the file /etc/domainips
Remove/delete the line that contains the IP and its current dedicated domain and save.

Next edit the file /var/cpanel/mainips/root
Add the IP you would like to share to a new line and save

At this point you should be able to go into WHM and assign the IP to multiple accounts.

See section “Shared Hosting with suexec”

In such an suexec configuration, the correct permissions scheme is simple to understand.

• All files should be owned by the actual user’s account, not the user account used for the httpd process.
• Group ownership is irrelevant, unless there’s specific group requirements for the web-server process permissions checking. This is not usually the case.
All directories should be 755 or 750.
• All files should be 644 or 640. Exception: wp-config.php should be 440 or 400 to prevent other users on the server from reading it.
• No directories should ever be given 777, even upload directories. Since the php process is running as the owner of the files, it gets the owners permissions and can write to even a 755 directory.

find /home/username/public_html -type d -exec chmod 750 {} \;

To chmod files recursively using find:

find /home/username/public_html -type f -exec chmod 640 {} \;

(for higher security on wordpress)

I run suExec so each account will run as the owner of the account.

CSF is the first culprit if you are locked out of your own server firewall after too many failed login attempts from a certain IP.

The block was in your firewall, not cpHulk.
The IP was listed in /etc/csf/csf.deny and /var/lib/csf/csf.tempip and /var/lib/csf/csf.tempban
You can whitelist the IP in your firewall by placing the IP in /etc/csf/csf.allow, then running csf -r

Next you can place your external IP in the whitelist of cPHulk:

WHM > Security Center > cPHulk brute force protection > White/Black list > Quick Add your current external IP to: White List (Trusted IP List)
