While WHM provides the functionality needed to run a web hosting company, it will also adapt to a host’s existing infrastructure needs. Feel free to discuss your needs with our sales team, so they can refer you to the APIs, hooks, and scripts available for extending the functionality of WHM and cPanel.

As we mentioned above, WHM allows web hosts to:

• Create and modify new accounts, and
• Create and apply hosting plans (we call them packages).

Web hosts can also:

• Control which features are available to specific users,
• Customize the page displayed when an account is suspended,
• Email all the hosting customers on the server,
• Move accounts to a different hard disk, and
• Modify content within a new account when it is first provisioned on the server.

By default, users do not have shell (command line) access to the server. However, server administrators can grant limited or full permissions for any account.

As a web hosting company grows, it may begin to have multiple servers running cPanel and WHM. Fortunately, it’s easy to transfer accounts among WHM servers. If a company needs to migrate an account from another control panel application, WHM can handle that as well. Server administrators can also restore account backups made by new customers migrating from another web host. This allows the customer to bring the website back online far quicker than would be possible with a manual migration.

With WHM, hosts can allocate large blocks of resources to reseller accounts. Reseller accounts are hosting accounts that have access to the account management functionality of WHM. They do not have full access to the server, only the access necessary to manage multiple hosting accounts. Resellers and server administrators can completely brand the appearance of the cPanel interface for their customers. We use industry standards such as CSS to make this process easy.

Hosts looking for a billing automation solution should feel free to contact our friendly sales team. They can refer you to solutions that work well with our software.

Before system administrators began using WHM, services run by a server could be down for hours or days before the administrator was notified. With WHM, if any server software fails, WHM will automatically restart that software and let the administrator know via IM, pager, email and/or SMS (phone). This allows the administrator to investigate the cause immediately, potentially averting a catastrophic server failure.

WHM will also notify the system administrator if there’s a lack of available hard disk space. It offers a tool for administrators to monitor hard disk utilization so they better understand what corrective actions should be taken. Server administrators can also monitor server load via WHM, as well as review daily reports of processor utilization, pinpointing which processes are using the most processor power.

Server reliability also requires preventing the server from being compromised. WHM’s Security Center allows administrators to implement powerful security measures with a click of a mouse. Our software offers a wide variety of functionality, from brute force to spam protection.

Using outdated web applications is a common cause of security weaknesses for web servers. Our cPAddons framework will notify hosting customers when their web applications are out-of-date, if they installed them via cPanel. Server administrators can also use WHM to forcefully upgrade out-of-date web applications.

With WHM, server administrators can easily control the technologies their servers employ. Using our exclusive EasyApache utility, server administrators can, with a few clicks:

• Support new web technologies (including security measures such as suPHP and suEXEC),
• Change the web server software powering the sites on the server, and
• Install new software modules to give web developers the tools they need for custom scripts.

In the Service Configuration section of WHM, administrators can manage the configuration for FTP, email and web services, and more.

WHM offers robust control over email. Server administrators can choose to automatically block spam before it ever reaches the server. Administrators can also let the server automatically tap into a pool of knowledge regarding which servers are sending spam, so the mail server software knows not to accept spam from those servers.

If a server administrator finds a useful application or programming language module, he or she can very easily install it via the WHM interface.

WHM can automatically update the server’s cPanel and WHM software package, as well as other server software cPanel and WHM rely on. The administrator can choose to update the server frequently with the newest version available, or only use thoroughly tested versions of the software. Automatic updates can also be disabled.

WHM automatically handles the formerly mundane and repetitive task of creating the necessary DNS entries for every new hosting account; however, administrators can customize the DNS zone templates that WHM uses. They can also set up custom shell scripts to execute before or after certain tasks are completed (for example, whenever a new account is created).
