In this tutorial we are going to learn how to configure a subdomain to a different IP address through the WHM control panel. Usually, it is mostly used by the online websites having a shopping cart.

For example: If example.com is you main site hosted on server “ABC” and the shopping cart “shop” is hosted on the server “XYZ”, and if you wish to show example.com is also hosted on the dedicated server “XYZ”, you will need to setup a subdomain pointing to a separate IP address.

Requirements for Setting up a Subdomain to a Different IP Address:

• Cpanel Control Panel Access
• WHM Access
• Different IP Address or Hostname

Step 1: Log in to your WHM control panel. In the left pane, under the DNS Fuctions, click on the Edit DNS Zone option as shown in the image below.

Step 2: Now, scroll the page and come to the section “Add New Entries Below this Line”. Here we are going to “Add the A Record”. In order to create a new A record, type “shop” in the first box under the “Add New Entries Below this Line”. From the dropdown menu select “A” as record type. Once you select the A record it will show another box infront of the drop down menu. Enter the IP Address or hostname to in order to mask/point it. (See image below)

Step 3: Make sure that subdomain with similar name doesn’t exists in the users account or the mask will not work as it should.

In the CDP 3.0 version, the Backup Scheduler is known as “Policy”. The policy feature allows you to schedule policy in two different ways. You can either schedule recurring policies or create one-time policy. In order to schedule a policy (backup) in CDP 3.0 follow the instruction given below:

There are three important things (Agent, Volume and Disk Safe) which must be already created before you proceed with the steps below. If you don’t know how to create them, check out the following CDP 3.0 tutorials:

How to Create an Agent in CDP 3.0 Enterprise Edition ?
How to Create a Volume in CDP 3.0 Enterprise Edition ?
How to Create a Disk Safe in CDP 3.0 Enterprise Edition ?

Let’s proceed. We assume that you have already logged in to the CDP 3.0 server.

Step 1: Click on the “Policy” option listed in the Dashboard menu. (see image below)

Step 2: Next, click on the “Create New Policy” located in the top left pane. (see image below)

Step 3: When you click on “Create New Policy” a new popup window will appear. (see image below)

Hard Quota – Backup place size

Groups:

Here you can assign a group(s) to the volume. Select a group from the drop-down menu and hit the “Add” button.

Users:

Here you can assign user(s) to the volume. Select a user from the drop-down menu and hit the “Add” button.

Step 5: Once you are done with the Volume settings, click on the  “Create” button at the bottom of the window to create a new volume to the system.

Step 6: If the folder doesn’t exist, it will come up with a notification window. You will need to confirm your request by clicking on the “OK” button. (see image below)

Step 7: When you click on the “OK” button, after a few moments you will be informed by a notification window, if the Volume is created successfully. (see image below)

Step 8: Hit the “OK” button on the notification window and the Volume will appear in the “Volumes” list.

Step 5: For this particular agent, you can set the Group’s special permissions. However, the groups’ permissions can only be changed when:

• Adding an Agent
• Editing an Agent
• Adding a Group
• Editing a Group

Step 6: Select a group of your choice and define the special permissions for it. When you select a group you will see several boxes in the “Groups”:

• Full Control – gives you the ability to control everything mentioned below.
• Editing agent’s settings
• Browsing agent’s recovery points
• Manipulating disk safes for agent
• Editing agent’s users
• Manipulating policies for agent
• Viewing agent’s task in the task history console
• Restoring files from agent’s recovery points

If you want to remove a group from the agent properties window, simply click on the “X” icon shown in the red color.

Step 7: Same way as “Groups”, you can set special permissions for the “Users”.

Step 8: Once you are done with all the settings, click on the “Create” button at bottom of the window.

Step 9: After a moment you will see a notification window showing “Successfully created agent” message. Click on the “OK” button.

Once the Agent is created it will appear in the Agents list and the Operating System (OS) of your dedicated hosting server will be detected automatically.

That’s it!

What is Leech Protection ?

The Leech Protect utility available in cPanel enables users with preventing users from disclosing the passwords to a restricted area of a website publicly and restricting the number of times a user can log in to the areas. The site administrators get the capability of redirecting the accounts to preferred pages incase of such violations. Hence protecting the breach into the system.

cPanel control panel allows the capability to manage leeching by redirecting or potentially suspending the user. A maximum number of logins can be set according to your preferences, while the default value is set to 2 hours. If incase the limitations tend to exceed, the user is assumed to be offering other users the login details.

Inorder to enable this feature, one must login to your cPanel control panel. You may refer the following links to learn the ways to access cPanel :

• cPanel For Beginners
• Ways to access Cpanel (control panel)

How to Enable Leech Protection ?

Step 1 – Look for the Leech Protect icon located in the Security section of cPanel home screen for accessing the Leech Protect Menu

Step 2 – Browse and Click the folder for which you intend assign protection

Step 3 – Assign the number of times you intend to allow a user to login during a window period of 2 hours.

NOTE: A value of 4 can be considered to be ideal, anything below might suspend a genuine user who would probably have carried out attempts to connect due to failure of internet connectivity. Though, if the login attempts are made through the same network or even a subnet, suspension of the accounts doesn’t occur.

Step 4 – You must update the URL of the website where you intend to send the users that are violating the accessibility criterion’s and the set number of login attempts.

NOTE: You may encounter an internal server error message if the updated URL isn’t something other that of the leech protected area.

Step 5 – You also have an option to receive notifications for leeching attempts. Check the box besides “Send Email Alert” and update the email address in the field titled “Send Email Alert to” for receiving instant alerts on possible leeching attempts.

Step 6 – For suspending a particular account, you only need to click box besides the option titles “Disable Compromised Accounts”

NOTE: If user is caught in violation for accessing the leech protected areas, the account is suspended and the password disabled. For reactivating a particular account you are required to reset the password for that particular account.

Step 7 – You may now click on Enable for enabling leech protection. After which a Leech Protect Confirmation screen would appear.

How to Disable Leech Protection ?

Disabling Leech Protection is simple process. You only need to click the Disable button after which you’d be see a confirmation statement.

You may reconfirm whether the changes to have been implemented by going back by clicking the link provided on that page. If you don’t notice the leech icon against the directory which you had previously protected that means it has been successfully disabled, else you may attempt the same procedure.

How to Manage the Users in Leech Protected Directories ?

Upon accessing the leech protected directory, you would observe an option titled Manage Users in the form of a button (you must scroll down to the end of the page to view). Then you’d be shown with the Password Protected Directories configuration area for the particular directory. You may wish to check the Password Protect Directories document to know more on the topic.
