Overview<\/h2>\n

First-time users who try to log in to WHM on newly-installed servers will frequently see a security warning. Newly-installed servers without a fully-qualified domain name (FQDN) as a hostname will automatically receive one from cPanel, L.L.C. The hostname will be a subdomain of cprapid.com<\/code>.<\/p>\n

Why do you need an automatically-issued hostname?<\/h2>\n

The first time a user tries to log in to WHM on a newly-installed server, they will see a security warning. It can be scary, especially for users on a trial license running cPanel & WHM for the first time.<\/p>\n

This happens because most modern browsers will display a warning whenever a user tries to visit a site or domain with an invalid or self-signed certificate.<\/p>\n

cPanel & WHM attempts to secure your server immediately after installation. First, it installs a self-signed certificate to secure the server. Then, it requests a free hostname certificate from our Certificate Authority to secure the server.<\/p>\n

However, sometimes a user does not set a resolvable FQDN as the server\u2019s hostname. So, the Certificate Authority cannot<\/strong> issue a certificate for the server. The self-signed certificate remains on the server, and the new user will see a warning when they try to log in to WHM.<\/p>\n

How it works<\/h2>\n

To allow the Certificate Authority to issue a certificate, we will automatically issue hostnames to newly-installed servers without a valid FQDN hostname.<\/p>\n

The installer script check the hostname of a newly-installed server. If the hostname does not resolve to the server\u2019s IP address, the script requests an automatically-issued hostname from cprapid.com<\/code> domain. The cprapid.com<\/code> nameservers will generate a new subdomain and point it at the server\u2019s primary IP address. The server will use that subdomain as a hostname to request a certificate from the Certificate Authority and install it.<\/p>\n

By the time the user logs in to WHM for the first time, the certificate is installed and ready, so no security warning appears.<\/p>\n

Limitations<\/h2>\n
    \n
  • \n

    The auto-issued hostname only issues a FQDN under the cprapid.com<\/code> domain and points it to the main IP address of the server.<\/p>\n<\/li>\n

  • \n

    You cannot<\/strong> manage the subdomain or delegate the subdomain to any other server.<\/p>\n<\/li>\n

  • \n

    To create subdomains for nameservers, you must<\/strong> set the server to use a hostname from a domain that you control. Nameservers under the cprapid.com<\/code> domain will not<\/strong> be fully functional.<\/p>\n<\/li>\n<\/ul>\n

    Taking flight<\/h2>\n

    We encourage users to replace the auto-issued hostname with an existing domain or purchase a new domain to generate a hostname. Using your own domain name and hostname will help establish your company\u2019s brand.<\/p>\n

    To change the server\u2019s hostname, use WHM\u2019s Change Hostname<\/em> interface (WHM >> Home >> Networking Setup >> Change Hostname<\/em>).<\/p>\n

    After a user changes the server\u2019s auto-issued hostname to their new hostname, the Certificate Authority will issue a new certificate for the server and the change should be seamless.<\/p>\n

    Caveats<\/h2>\n

    If a partner disables the free hostname certificate service for their customers Manage2\u2019s Update Company Information interface (Manage2 >> Dashboard >> Company >> Update Company Information<\/em>), the server will still use the self-signed certificate. Because of this, they will see the security warning when they try to log in to WHM.<\/p>\n

    Also, if a partner uses a post-installation script to assign a hostname to the server, the script will continue to work as expected. If partners use a pre-installation script to assign a hostname to the server, that hostname must be a FQDN that resolves to the server or it will be replaced by an auto-issued hostname.<\/p>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"
