Easy Apache (EA)

• It is a part of cPanel WHM. It is meant to
  install, modify and validate the Apache web
  server, PHP and other components of a user.

• Whoa! Thats a big number, arent you
  proud?

Elliptic Curve Digital Signature Algorithm
(ECDSA)

• It is a variant of the Digital Signature
  Algorithm. Elliptic-curve cryptography (ECC) is
  used by it. Equivalent security is provided by
  ECDSA to RSA keys, using smaller key sizes.
• ECDSA provides equivalent security to RSA keys
  that are using smaller key sizes. Hence, smaller
  certificates are generated by ECDSA keys. The
  result is faster connections and website loading
  times, owing to smaller certificates.

7
Email Deliverability

• It refers to the ability of a system to deliver
  email to recipients. It can frequently gauge the
  success of email campaigns. It also aids in
  identifying mail-related DNS problems. A user can
  view email deliverability information in the
  Email Deliverability interface in cPanel, by
  clicking on cPanel -gt Home -gt Email -gt Email
  Deliverability.
• In the context of Internet, it is imperative to
  mention websites. The files of websites are

• These features might not work with other settings
  or features and are not effective controls with
  regard to security.

13
Extended Fourth Filesystem (ext4)

• It is a filesystem that is journaled and is often
  used by Linux servers. All cPanel WHM
  installations require ext4.
• ext3 filesystem is the predecessor of ext4.

14
Extended HELO (EHLO)

• It is an Extended Simple Mail Transfer Protocol
  (ESMTP) command. It is sent by an email server or
  client. Its purpose is to identify the email
  server or client when it establishes a connection
  with another email server. The process of sending
  an email is initiated by this command, which is
  followed by the server sending its domain name.
  The receiving server or client is notified by the
  esmtp command that ESMTP extensions are supported
  by the sending server.

15
Extended SMTP (ESMTP)

• It is an extension of the original SMTPs (Simple
  Mail Transfer Protocol) protocols. An
  EHLO request is sent by ESMTP to an email server
  or client. This is done to identify the servers
  supported protocol. A list of the servers
  available ESMTP commands are returned by it.

16
Extended Validation (EV) Certificate

• It refers to a digital certificate
  for SSL/TLS verification. A comprehensive
  identity validation process is used by the
  certificate authority (CA) to verify the control
  of the applicant over the DNS domain. HTTPs are
  enabled by these certificates on the web browser
  address bar of a user. These state the name of
  the verified owner. The most secure level of
  domain validation is offered by these

  server can be selected in the FTP Server
  Selection interface in WHM, by clicking on WHM
  -gt Home -gt Service Configuration -gt FTP Server
  Selection. It can be configured in the FTP
  Server Configuration interface in WHM, by
  clicking on WHM -gt Home -gt Service Configuration

  on cPanel -gt Home -gt Files -gt FTP Accounts.
• To digress, websites are hosted on the servers
  that are provided by web hosting companies. These
  companies are often known as the Best Windows
  Hosting Company or as Cloud Hosting Company in
  India or even as Website Hosting Companies in
  India.

19
Filesystem

• It is the system that is used by the operating
  system in order to manage files and directories.
  If multiple partitions are used by a users
  server, then a different filesystem might be used
  by each of those partitions.

20
Filter

• It is that tool in cPanel which processes email
  based on the users preferences. WHM users can
  set up many types of filters.
• A user can apply filters to a domains main email
  account by using the Global Email
  Filters interface by clicking on cPanel -gt Home
  -gt Email -gt Global Email Filters.
• Filters can be customized for individual accounts
  by using the Email Filters interface. The path
  for achieving that is, cPanel -gt Home -gt Email -gt
  Email Filters.

21
Firewall

• It refers to a security application that is meant
  to protect servers from attacks initiated by
  hackers.

22
Firewalld

• It is a firewall tool that is meant for Linux
  operating system. Network and firewall zones are
  managed dynamically by it. Additionally, it
  defines trust levels.

23
Forceful Reboot

• It refers to one of the two methods that can be
  used by a user to restart his/her server. The
  server is forced to restart by this method,
  irrespective of the errors that are encountered
  by it.
• Its use is recommended only in those situations
  where a graceful reboot doesnt work. That is
  because it can cause data loss. Both, forceful
  and graceful reboots can be performed in the WHM
  interface.

24
Forwarder

• It is a tool that enables a user to forward a
  copy of every email message that has been
  received by him, to some other address. Even if a
  forwarder is present, the user will still
  continue to receive mail at the original
  recipient address.
• In the scenario where a forwarder is created by
  the user prior to the creation of the original
  address, the messages will be forwarded by the
  system to the end address and not to the original
  address as it is not in existence. Forwarders can
  be created and managed in the Forwarders
  interface in cPanel, by clicking on cPanel -gt
  Home -gt Email -gt Forwarders.

25
Fully Qualified Domain Name (FQDN)
