To access cPanel:
- Type: https://IP:2083 into your preferred Internet browser.
- IP is meant to stand for your website’s IP address.
- Approximately one week after setting up your website, you will be able to access your cPanel interface by replacing the IP address with your domain name.
- You will be greeted by a cPanel startup page on your first login. We strongly recommend completing the Getting Started Wizard.
Note: A colon symbol following an IP address or domain name denotes a specific port number. These port numbers are responsible for guiding data packets transmitted between 2 computers to specific processes taking place on either machine.
Changing the cPanel interface's language
As of cPanel 11.32, you can select the language in which the interface should appear from the login page. This change will only apply to the specific browser session. Selecting a new language from the login screen will not change your account's default language (set using the Change Language screen).
Note: If your browser's Accept-Language header is set, then the login screen will attempt to display the corresponding locale. If the locale requested by the browser header is not available, the login interface will appear in English.
The cPanel Home Screen
For cPanel version 11.36
The cPanel home screen provides access to all of your cPanel functions.
You can reach the cPanel home screen from anywhere in the interface by clicking the Home button () at the top left corner of the screen, or the Home link at the bottom of the screen. From the Home screen, you can reach any of cPanel's features.
You can change the order in which the feature-related boxes, such as Mail and Files, appear on your home screen. This can be useful for organizing the cPanel interface to better suit your needs. To change the location of a box:

cPanel & WHM GlossaryFor cPanel & WHM version 11.36
“A” (Address) Entry: A record, residing on your server, that contains your server’s hostname and IP address. The “A” entry is essential because it tells DNS servers the identity of your server, allowing visitors to find your server on the Internet.
Addon Domain: An additional domain name associated with a cPanel account. Each addon domain is stored in its own directory that can be configured by website owners. This allows website owners to manage multiple domains from a single cPanel account. Addon domains must be registered with a domain name registrar to properly function.
AIM (AOL Instant Messenger): A widely used instant messaging program. WHM can notify you via AIM if there is a problem with your server. More information about AIM can be found at http://dashboard.aim.com/aim.
Anonymous FTP: A process whereby visitors without FTP accounts may upload and download files to and from a website. Although it poses security risks, anonymous FTP can be convenient if the site owner wishes to make files publicly available for downloading. When setting up anonymous FTP, it is important to protect any sensitive information by changing file permissions and directory access permissions.
Apache Handler: A means of telling the Apache software how to process a given type of file. By default, Apache only handles certain file types. You can configure Apache handlers for other file types using cPanel. For more information, see Apache's handler documentation.
Authentication: A process for confirming the identity of someone with whom the server will share sensitive information. On the web, authentication usually involves either a username and password set or a public/private key pair.
Autoconfig: A process that sets up a user’s Outlook® or Outlook Express account to receive their cPanel email. You can enable or disable this feature using WHM's Enable/Disable Outlook® Autoconfig feature. This feature was not available in WHM version 11.34, but is available again in version 11.36.
Auto Responder: Auto responders allow you to automate replies to incoming email. In cPanel, this feature can be useful for confirming the receipt of mail, or for informing correspondents that the recipient is unavailable (for example, while on vacation).
AWStats (Advanced Web Statistics): A program that provides information about the visitors of a website. This information is presented in both graphical and statistical views. More information about AWStats can be found at http://awstats.sourceforge.net/.
Backscatter: Bounce email messages (or failed Delivery Status Notifications) erroneously sent to a domain whose name has been forged as the sender of spam. Using SPF on your mail server should reduce backscatter.
Bandmin: Bandmin is a set of Perl scripts that monitor and log bandwidth usage by IP. You can access Bandmin at the following location:
example.com is your domain name).
Bandwidth: The amount of data transferred to and from a server. Every time a visitor views a file (whether it’s a web page, image, video, or audio file), that file is transferred to the visitor’s computer. Bandwidth is the total size of all these files transferred to visitors’ computers. Hosting providers often limit a site owner's bandwidth, as it can affect the performance of the server.
Bayes Testing (aka Bayesian Spam Filtering): Bayesian spam filtering is a method of filtering spam based on statistics. This method uses tokens, generally words, found in emails to determine whether an incoming message is spam. This filtering technique relies on Bayesian statistics. Bayesian classifiers calculate a probability that an email is or is not spam by correlating the use of tokens with spam and non spam emails.
Blackhole: An option for handling mail received by the default or catch-all email addresses of cPanel users. The “blackhole” option discards mail after it is accepted; for this reason, it can result in more spam being sent to your users, and it places a larger load on your server than the “fail” option.
Blocker: A blocker is a check that is performed before a version change takes place. This check reviews your system for possible compatibility issues with a desired upgrade. This concept was introduced in 11.30.
BoxTrapper: An application included with cPanel that filters spam by requiring would-be senders to reply to a verification email (also known as challenge-response verification). The original email will only be accepted after the sender replies to the verification message.
BoxTrapper Blacklist: A list of email addresses from which incoming mail will be automatically blocked by the BoxTrapper application. cPanel automatically sends a configurable warning message upon receipt of mail from a blacklisted address. See also BoxTrapper Ignore List and BoxTrapper Whitelist.
BoxTrapper Ignore List: A list of email addresses from which incoming mail will be blocked. cPanel does not send a warning message upon receipt of mail from an address ignored by the BoxTrapper application. See also BoxTrapper Blacklist and BoxTrapper Whitelist.
Brute Force (Attack): A type of attack wherein the attacker enters a large number of combinations of characters, in an attempt to decrypt a key. WHM includes cPHulk, a protection system that lets you lock out brute force attackers after a specified number of failed attempts.
CA (Certificate Authority) Bundle: A file on your server that verifies that your public and private keys were issued by a trusted entity. If your Certificate Authority sent you a CA bundle file, you can install it to your server using WHM’s Install a SSL Certificate and Setup the Domain feature, or the Manage Service SSL Certificates feature.
Cache: A stored piece of information to which the server refers instead of accessing the information source, to save bandwidth and time. In WHM, you can configure caching of DNS records using the Edit DNS Zone feature. You can configure caching of disk usage data via the Tweak Settings page.
CGI (Common Gateway Interface): A protocol that lets a web server communicate with scripts and other software. cPanel’s CGI Center provides an array of CGI scripts that let website owners generate and manage useful features for websites, including a guestbook, clock, hit counter, countdown clock, and banner ads.
Character Set: (Also sometimes known as “charset”). A code that pairs a sequence of characters with a set of numbers, allowing a computer to store and transmit the characters. ASCII is one popular character set; several character sets exist for Cyrillic and Asian alphabets. More information about character sets can be found at http://en.wikipedia.org/wiki/Character_set.
CIDR (Classless Inter-Domain Routing): A routing method that assigns each Internet user to a four-part IP address, with each part separated by a decimal, followed by a slash and a number between 0 and 32.
Compiler: A computer program that translates source code written by people into a language readable by a computer. As a security measure, WHM allows you to disable your web server’s compilers for most users.
cPAddons: Pieces of software that website owners can install on a website through cPanel. cPAddons provide useful tools to a website. Common examples include bulletin boards, chat programs, and online shopping carts.
CPAN (Comprehensive Perl Archive Network): The main repository of Perl modules, pieces of Perl software. The CPAN library (located at http://www.cpan.org) contains over 12,000 modules, most of which are free of charge. cPanel allows you to search CPAN and install Perl modules.
CSR (Certificate Signing Request): A request, which you send to a certificate authority, for an identity certificate. cPanel can generate a CSR for you, but since authorities vary with regard to the information they require, you should check their requirements before applying for a certificate.
cupsd: Common Unix Printing System Daemon, used by the web server for printing. This daemon is disabled by the WHM Quick Security Scan feature. We strongly suggest disabling
cupsd as it is vulnerable to attacks.
CVE (Common Vulnerabilities and Exposures) System: An archive of publicly known security threats, vulnerabilities, and exposures. The CVE system assigns numbers, known as CVE identifiers. These identifiers provide a reference point when evaluating the coverage and effectiveness of security tools and services.
Data Center: A facility used to house servers. A data center is generally a safe place to keep a server as it typically includes backup power supplies, multiple communication connections, and environmental controls.
DNS (Domain Name System): The component of the Internet which acts as a “phone book,” converting human-readable domain names (such as
www.example.com) into computer-readable IP addresses (such as
18.104.22.168, in the case of
DNS Zone: An administrative space or portion of the Domain Name System. This space is responsible for directing web traffic to the correct location. An example is
example.com, a DNS zone whose servers direct its web traffic.
Domain Forwarding: A technique that allows you or your users to automatically send visitors to a domain when they access another domain. For example, a user may reach
example.com by typing
example2.com. See also redirect.
EIDE (Enhanced Integrated Drive Electronics): A method for connecting hardware to a computer. WHM’s Optimize EIDE Hard Drives? feature can speed up communications between your server and external hard drives connected by EIDE.
Environment Variables: Values that advanced administrators place within specific files on the server to change the behavior of Apache and PHP. More information about environment variables can be found here.
Error Pages: These pages display warning messages when visitors encounter problems while trying to access your site. cPanel lets you configure the error messages that display for your site. For an in-depth look at HTTP error codes, please visit our HTTP error codes documentation.
Filter: In cPanel, a tool that processes mail according to your preferences. For example, a filter can automatically discard spam or save mail from a specified sender to its own folder. In cPanel, filters can be applied to the main email account on a domain (Account Level Filters), or customized for each individual account (User Level Filters).
Forceful Reboot: 1 of 2 methods for restarting your server. This forces the server to restart regardless of what error(s) it may have encountered. You should only use a forceful reboot if you cannot reboot gracefully, as it may case data loss.
FormMail Clone: A piece of software that imitates the function of FormMail. FormMail is used to create an email message from data that a user enters into the text fields on a web page, and send the message to the intended recipient.
Forwarder: A tool that lets you forward a copy of every email message you receive to another address. When a forwarder is set up, you will still receive mail at the original recipient address. If, however, you create a forwarder without first creating the original address, messages will be forwarded to the end address without being sent to the original address, as it does not exist.
FQDN (Fully Qualified Domain Name): A name that uniquely defines a domain’s location. It is usually seen as
host.example.com. with a trailing dot. For the purposes of cPanel, including a final dot is not necessary, but the domain name must contain at least 2 dots. FQDNs must be written in lowercase letters.
FrontPage®: A Microsoft® application that allows site owners to edit a web page in WYSIWYG (“what-you-see-is-what-you-get”) format, rather than using raw HTML code and CSS. WHM provides FrontPage extensions, so site owners can publish their sites using FrontPage, allowing them to skip the FTP process.
FTP (File Transfer Protocol): A method of transferring files from one computer to another. cPanel & WHM comes equipped with an FTP server that can be configured to the website owner's preference. An FTP client must be installed on the local computer in order to send files to and receive files from the FTP server. Some FTP clients include FileZilla (for Windows®, Linux, and Unix), and Cyberduck (for Mac®).
Generators (web stats): Pieces of software that will compile statistics for your web server. For example, they can tell you how much bandwidth has been transferred per domain. 3 generators can be configured through WHM: Analog, AWStats, and the Webalizer.
gzip: A program which compresses files for disk space conservation, minimizing transfer times, and making the transfer of multiple files easier. The compressed files use the filename extension
.gz. In Unix and Linux systems,
gzip is often used with
tar to create a “tarball” file (which ends with
Home Directory: A cPanel account’s highest-level directory, which contains all the files and directories used by websites managed by the account. Files placed in a home directory are not viewable online unless they reside in the
public_html directory or a subdirectory of
