What You Get from cPanel® & WHM®
cPanel & WHM software provides hundreds of features to help you easily manage your website or server. We have developed what we believe is the ultimate feature matrix.
WHM® Software Features
The start-up wizard should properly assist you in configuring your server when you first install cPanel & WHM software. However, if you need to change any of the configuration options, you can do so by accessing the Server Configuration icon located on the home screen.
- Basic cPanel & WHM Software Setup
This feature allows you to configure some basic options for cPanel & WHM software. You can specify contact information, nameservers, and more.
- Change Root Password
This feature allows you to change the root password of your web server without the old password.
- Initial Quota Setup
This feature initializes a scan to ensure disk quotas are being used where your cPanel software users store their files.
- Server Time
This feature allows you to set your server’s time zone and synchronize its time with the time server. Your server’s time needs to synchronize with the time server for your license to work.
- Statistics Software Configuration
This area of WHM software allows you to view information about your server’s statistics and statistics software.
- Tweak Settings
On this page, you can configure a number of settings related to the functionality of cPanel, WHM software, and associated services.
- Update Preferences
This feature allows you to define an update configuration for WHM and cPanel software. For example, you can specify whether you would like the interfaces to update automatically or manually.
This area of WHM software allows you to determine how your customers will contact you for support, and provides cPanel and WHM® software support for you.
- Configure Customer Contact
Using this feature, you can specify how your customers should contact you with support requests.
- Support Center
The Support Center offers a number of links for accessing cPanel & WHM software support features. Change Hostname
- Resolver Configuration
This feature allows you access to a configuration wizard for editing the /etc/resolv.conf file. This file will contain the names of the nameservers that your server will query in order to convert, or‚ “resolve” domain names into IP addresses.
This section of the WHM software interface can be used to configure your server for use on the Internet.
- Change Hostname
This feature allows you to change your server’s hostname.
- Nameserver IPs
This feature allows you to add and remove nameserver IP addresses on your server. This is useful if you need to modify the nameserver configuration you already set up using the Basic cPanel & WHM Setup screen. This feature was moved to the DNS Functions section of the WHM software interface.
- Resolver Configuration
This feature allows you access to a configuration wizard for editing the /etc/resolv.conf file. This file will contain the names of the nameservers that your server will query in order to convert, or “resolve,” domain names into IP addresses.
Using the security functions, you are able to better secure your server. You may fix any insecurities with SuEXEC or CGI, as well as manage SSH keys, users, and more.
- Apache mod_userdir Tweak
The mod_userdir feature provides the ability to view websites on your server by typing your hostname followed by a tilde and the website owner’s username. (Example: http://host.example.com/~username) Restricting this type of access is desirable, as it allows users to circumvent bandwidth limits.
- Compiler Access
Many common attacks require a working C or C++ compiler on the server. Disabling these compilers will result in a more secure server.
- Configure Security Policies
This interface allows you to configure security measures for your server and your account.
- cPHulk Brute Force Protection
Brute force is an attack (hacking) method that involves using an automated system to guess the password to your web server or services. cPHulk helps defend your server against such attacks.

- Shell Fork Bomb Protection
This feature will prevent users with terminal access (SSH or Telnet) from using up the system’s resources and potentially crashing your web server via a malicious attack known as a fork bomb. Fork bombs work by starting a cascade of small processes that duplicate themselves until the server’s resources are depleted.
- SMTP Tweak
You may want to prevent users from bypassing your mail server to send mail. This is common practice for spammers. Use this feature to configure your server so that the mail transport agent (MTA), Mailman mailing list software, and root user are the only accounts able to connect to remote SMTP servers.
- SSH Password Authorization Tweak
This feature allows you to tweak your SSH authentication by enabling or disabling passwords. If passwords are disabled, users will be forced to use keys when using SSH to access your server.
- Traceroute Enable/Disable
The traceroute utility is a network tool that can be used to determine the route taken by information (packets) sent across the Internet. This often is the first step in pinpointing weaknesses for mounting an attack.

This area of WHM software allows you to configure a number of servers to share DNS information, and to create a trust key relationship between those servers.
- Configure Cluster (Documents the Configure Cluster screen)
A DNS cluster is a number of nameservers that share records. Clustering allows you to physically separate your nameservers so that in the event of, for instance, a power outage, you still have DNS functionality. This way, visitors can reach websites on your server more quickly after the web server comes back online.
- Setup Remote Access Key
This feature can be used to generate an access key. This access key can be used for automatic account creation scripts, external billing software, and allowing servers in your DNS cluster to exchange records.
The WHM® interface offers you two methods for rebooting your server. The method you should employ to reboot your server depends upon the events leading up to the reboot.
This method will shut down the computer regardless of what error(s) the server has encountered. It is preferable to reboot your system using this method versus using the physical reset switch (a hard reset). However, a graceful reboot is preferable to a forceful reboot as a forceful reboot can cause data loss.
These restart method is preferred to any other. This allows the server to close any user-level running processes before restarting, storing data as it does so. This reboot method will not result in data loss.
This set of features allows you to access several lists to view information regarding your server. This can be helpful when troubleshooting both hardware and software issues.
- Apache Status
Apache is a web server daemon (httpd). It is responsible for responding to HTTP requests, subsequently serving a web page.
- Daily Process Log (formerly CPU/Memory/MySQL Usage)
This feature displays information about your server’s consumption of processing power and memory, averaged over the course of the selected day.

For example, you can change the master password for an account, IP addresses associated with accounts, or primary contact email addresses. In order to access many of these functions you must click the edit icon.
- List Parked Domains
A parked domain is a domain that simply points to another domain. You may assign multiple domain names to point to your domain using parked domains. For example, cpanel.com is parked on cpanel.net, allowing users who type www.cpanel.com to reach cpanel.net.
- List Subdomains
Subdomains function as URLs for different sections of a website. For example, example.com may have the subdomain documents.example.com for its documentation section; this may be easier for visitors to remember than example.com/documents.

- Copy an Account from Another Server with Account Password
This feature will attempt to copy an account from a remote server without using the root account. However, this feature is only intended as a last resort. If the remote server does not have a working copy of Perl, have CGI enabled, and have an unmodified cPanel software configuration, it is unlikely that the transfer will succeed. You should not attempt to transfer accounts greater than 250 Megabytes using this feature.
- Copy Multiple Accounts/Packages from Another Server
This feature will attempt to copy multiple accounts and packages from a remote server. This can be useful when a reseller would like to move a number of accounts from one server to another.
- Review Copied Accounts
This feature allows you to review any accounts that have been copied to your server.
A theme in cPanel & WHM software is, ultimately, the skeletal frame on which the style, or “skin”, is placed. This area of WHM software allows you to manage cPanel software themes. Note: We do not currently support custom theme or localization efforts for WHM.
- Change WHM Software Theme
This feature allows you to select the theme your WHM software interface will use.
- Universal Theme Manager
The theme contains many underlying elements like HTML and CSS. We recommend that you use the x theme for WHM software and the x3/x3mail theme for cPanel software, as these are the most current themes supported by cPanel.
Packages are limitations on resources an account is allowed to use. For example, you may specify how much disk space an account is allotted. These limitations are bundled and saved so that they can be applied to accounts later. This streamlines setting up new accounts, since you can sell predefined packages to your cPanel software account holders or resellers.
- Add a Package
This feature allows you to create a new package that can be applied to any account hosted by your server.
- Delete a Package
This feature will remove existing packages from your server. You should exercise caution when deleting packages as they cannot be recovered; you will have to recreate them.

SSL and TLS are cryptographic schemes that allow a visitor’s web browser to communicate securely with a web server. All sensitive data (credit card numbers, login information, etc.) that is transmitted over the Internet should be protected by SSL/TLS. TLS is simply the more recent version of SSL. This area of WHM® software allows you to perform several functions to help secure your server.
- Generate a SSL Certificate and Signing Request
WHM® allows you to generate an SSL certificate for your website. The function will also generate a corresponding private key and certificate signing request (CSR).
- Install a SSL Certificate and Setup the Domain
When you use this feature, WHM® software will automatically install your SSL certificate and private key in the correct directories. You may either paste the certificate and key into the fields on the screen yourself, or allow WHM® software to retrieve them.
- Manage SSL Hosts
This area of WHM® lets you share SSL certificates, and manage certificates by domain and user.
- Purchase and Install SSL Certificate
This feature will allow you to purchase an SSL certificate for installation directly from WHM® software. Currently, Trustwave® is the only the certificate authority that you can purchase from using this method.
- SSL Key/Crt Manager
This feature lets you view all of the keys and certificates installed on your server. The SSL Key/Crt Manager table displays each key, certificate signing request (CSR), and certificate on your server.
Using this feature, you can restart a service (usually a daemon) on your web server. Daemons are small processes that run in the background of your server.
Storage Space/Disk Space
cPanel & WHM® software allows you to create hosting plans that allocate how much disk space each hosting plan is allocated
cPanel & WHM® software allows you to create hosting plans that allocate how much bandwidth each hosting plan is allocated.
- Domain Management
Allow clients to host either a single domain or multiple domains per accounts. Multi-Domain hosting allows unique domains to be parked on top of the primary domain or pointed to a specific folder.
- Sub-Domain Management
Allow hosting clients to create variations of their primary domain name. Example: store.yourdomain.com, portal.yourdomain.com, blog.yourdomain.com
- POP3/IMAP Accounts
Allow hosting clients create and manage their own POP3/IMAP email accounts. cPanel & WHM provides the ability to create these accounts.
- Mail Client Configuration
When you access an email account through a desktop email application such as Outlook® Express®, the email application will require specific information about your email account. You can use the auto-configure options below to attempt to automatically configure your email application. If the available options are not compatible with your application, you will need to use the Manual Settings information.
- Forwards and Aliases
Create forwards and aliases so they are mapped out to another email address, application or external email address.
Both web site owners and email owners can create and manage auto responders.
- Account Level Filtering
Account Level Filters allow you to control granular aspects of your email and apply rules to inbound email.
- Spam Assassin
Spam Assasin is a free of charge anti-spam tool that helps reduce the number of unsolicited emails.
BoxTrapper protects your inbox from spam by requiring all email senders not on your Whitelist reply to a verification email before you can receive their mail.
- Mailing Lists (Mailman, www.list.org)
Mailing lists can simplify sending messages to a large group of people. You can add a group of email addresses to a mailing list to avoid typing those addresses each time you send a message. This can be very useful when sending newsletters or other updates to large groups of people.

Webmail allows you to access your email from any computer with an Internet connection and a web browser. Please make sure to log out when checking your email on public computers so that other people cannot read your email.
- Delivery Reports
- Email Delivery Route
- Email Authentication – Featuring: SPF and DKIM
Email authentication is the effort to equip messages of the email transport system with enough verifiable information, so that recipients can recognize the nature of each incoming message automatically. Enabling email authentication will help fight the spread of spam. Both of the methods below work to prevent forged mail from going in and out of your server. The great benefit of enabling these methods is to prevent mail from looking like it is coming from your domain(s). When enabled, these methods should reduce the amount of bounce messages or unwanted emails received when spammers “spoof” one or more of your email addresses.
- MX Record
An MX (mail exchanger) entry tells a client which server receives mail sent to a domain name. Hosting clients have the ability to control this.
- Mass Email Account creation
This feature allows you to use 2 types of files to create multiple email address or email forwarders for your account simultaneously. You may use Excel spreadsheet files (.xls) or comma-separated values sheet, aka CSV file (.csv) to import the data. A CSV file is a plain text file that has been given a .csv extension.

Easily create databases, users and control permissions for mySQL
Create forwards and aliases so they are mapped out to another email address, application or external email address.
- PostgreSQL w/phpPgAdmin
Easily create databases, users and control permissions for PostgreSQL.
PostgreSQL Databases allow you to store lots of information in an easy to access manner. The databases themselves are not easily read by humans. PostgreSQL databases are required by many web applications including some bulletin boards, content management systems, and others. To use a database, you’ll need to create it. Only PostgreSQL Users (different than mail or other users) that have privileges to access a database can read from or write to that database.

- Anonymous FTP Controls
You can allow users to connect to your anonymous FTP directory without a password. This may be useful for making files publicly available for download. Please note that allowing anonymous users to access any part of your system may be considered a security hole.
The Web Disk feature is cPanel’s software implementation of the WebDav protocol. This feature allows you to manage files associated with your website. By creating an account and accessing your Web Disk, you can navigate, upload, and download files to and from your web server as though they were part of your personal computer.

These are not automatically scheduled backups. Automatically scheduled backups need to be enabled by the server owner/administrator.
- Disk Space Usage
The cPanel® Disk Usage Viewer provides an overview of the disk space that your account is using. It shows disk usage totals for your account’s directories and all of its databases rather than for individual files or databases.
