What makes DA unique

A modern control panel's primary purpose is to effectively facilitate the routine management of your hosting infrastructure and present these tasks simply and intuitively to both the user and to you as the administrator.

While many available control panels claim to do just that, DirectAdmin offers many features that you just won't find elsewhere, making the DirectAdmin experience truly unique.

From a technical perspective, let's delve into more of the features that you'll love with DirectAdmin.

Nginx Unit

We've been working hard to bring you Nginx Unitopen in new window! A dream come true for polyglots, the Nginx Unit application server supports the following languages:

  • Perl
  • PHP
  • Python
  • Ruby
  • Java

Upcoming:

  • Go
  • Node.js

Nginx Unit allows you to run different versions of the same language, can deploy configuration changes without interruptions to services, and can run alongside any webserver. Several popular frameworks and web applicationsopen in new window run seamlessly with Nginx Unit, including frameworks such as Django, Express, Flask, and Laravel, and webapps including WordPress, Joomla, Drupal, Jira, phpBB, and MediaWiki amongst several others.

We use Nginx Unit to support multiple languages, while the competition usually utilizes Phusion Passenger for this purpose. Nginx Unit offers features that just aren't available with Passenger. Some of the benefits of Nginx Unit when compared to Phusion Passenger include:

  1. Multithreading (applications can use multiple cores)
  2. Native support for many languages not supported by Passenger (Java, Go, Assembly, Perl, and PHP).
  3. Support of Linux namespaces and chroot natively to isolate the users/applications from each other. Namespace and file system isolationopen in new window is available for operating systems that support it. You also have a choice between static or dynamic process managementopen in new window. More information hereopen in new window.
  4. Feature-rich. Nginx Unit as a standalone server supports routing, proxying and some other 'common webserver' features, such as HTTP/2 support. HTTP rewrites are planned. Proxyingopen in new window requests and load balancingopen in new window by defining upstream servers is also possible. You can even serve Nginx in front of Unitopen in new window to secure the Unit Control Socket (if you require the Control Socket to be accessible remotely, that is).
  5. ASGI support for Python. With ASGI, processing becomes asynchronous in Python. It lets you achieve high throughput in IO-bound contexts. Additionally, it fully supports WebSockets,which are bidirectional, low-latency, persistent connections between the server and the client that allows either participant to send messages at any time without the overhead of HTTP. Websockets are supported currently for Node.js, Java, and Python. Websocket support is planned for Ruby, Go, Perl, and PHPopen in new window.
Nginx Templates for shared webhosting

Nginx has no support for .htaccess, thus friendly-URLs do not work automatically. DirectAdmin officially supports Nginx Templates to support most common CMS (content management system) applications with a single click. Select "WordPress", "Drupal" or some other CMS from drop-down, save the selection and that's it! It also has an API available, so, plugins like Installatron or Softaculous could have it integrated easily and make it work automatically after the installation of a new application.

OpenLiteSpeed webserver support

OpenLiteSpeed is the Open Source edition of LiteSpeed Web Server Enterprise. OpenLiteSpeed contains all of the essential featuresopen in new window found in LiteSpeed Enterprise, including LiteSpeed cache support for common content management systems like WordPress, Joomla or OpenCart. See some benchmarks hereopen in new window conveying how well LScache performs. It offers .htaccess support for URL rewrites, and DirectAdmin offers a way to re-load OpenLiteSpeed automatically if any .htaccess changes are detected.

Nginx FastCGI cache for WordPress

Looking for an alternative to LScache (LiteSpeed cache)? We have it covered! You may use WordPress+FastCGI cache with your Nginx installation on your DirectAdmin server. Just select the WordPress+FastCGI cache template, install the WordPress Nginx Helper pluginopen in new window, and you have your blazing-fast WordPress site ready!

Feature sets

Customizable or built-in feature sets, which allow the control over which features are allowed in the account per package or account. Default Feature Sets may include the following:

  • DNS Only
  • E-Mail Only
  • Tickets
  • View Domain
  • Core Functions
Plugins as package items

Did you ever want to include more premium plugins with your premium plans only? The 'plugins as package items' feature lets you do it easily!

Rspamd, the Rspamd GUI, and many other email features

Rspamd support is offered as an alternative to SpamAssassin and provides better functionality. Rspamd is a drop-in replacement, so you'll notice that from within the user panel, the control options are unchanged. The same user_prefs syntax and settings are supported in Rspamd as with SpamAssassin. Rspamd also supports the addition of modules such as greylisting and Redis cache.

Other email features include : RBL blockingopen in new window, EasySpamFighter and Blockcracking SpamBlocker modules, Exim filters, Pigeonhole Sieve language filtering support, Dovecot Full Text Search (FTS) with fts-xapian, Managesieve Roundcube sieve support, Whitelists/Blacklists, Daily per-user/per-account/global Email Limitsopen in new window, and so much more!

Real Time Performance Monitoring at a glance with Netdata

Netdata offers stunning visualizations and detailed graphs in real time to help you troubleshoot, monitor, and understand your server's performance and resource usage. While extremely detailed, the display couldn't be more alluring. It offers tons of software integrationsopen in new window, too. Enough said... check out a preview hereopen in new window!

MX templates

DirectAdmin includes, by default, some popular MX Templatesopen in new window for a faster MX record configuration. ‥Google Suite MX”, ‥Microsoft 365” and ‥Zoho Mail” are all offered as pre-configured choices. Other remote mail servers' MX records could be included in the MX template choices available by an admin if needed. Changing a mail server for the domain is as easy as selecting mail provided from the list, no more mess with DirectAdmin DNS record control for your end-customers!

Security

Login Keys

Users can create login keys that will essentially function like a second password for that username. The key can be set to:

  • only be allowed to run certain commands (similar to commands.allow and commands.deny)
  • have an expiry date
  • have a limited number of executions (e.g., 1, 2+, or unlimited)
  • allow only the specific IPs or IP ranges listed to use that key.

Login keys are useful for many reasons, such as remote API calls, for example. You could create a login key that allowed access only to CMD_DNS* and CMD_API_DNS* functionality for a dynamic DNS script that makes calls to the server to update your local machine's hostname A record when the machine's IP has changed, for example. Another example of when this would be useful, you could create an admin login key restricted to your support team's IP addresses, and then provide this to your support team in lieu of your admin password.

Bubblewrap/JailShell

Better security is provided by using a bubblewrap for PHP, SSH, and crons, which actually does 'lock' a user in their own file system. This serves as an alternative solution to CageFS for those not using CloudLinux.

Direct CSF/LFD integration, the DirectAdmin BruteForce Monitor, and ModSecurity

Direct integration with CSF and BFM was implemented in DirectAdmin. This ensures that these security resources work together optimally to provide multiple layers of protection and prevent unauthorized access. BFM now also monitors ModSecurity logs(https://directadmin.com/features.php?id=2861)! So, you can have all three resources working together to ensure attackers are blocked.

User controlled per-domain ModSecurity flags

This featureopen in new window enables Users to skip some mod_security rules, or fully disable them when needed. This can be disabled if desired by the root user.

Automatic Disabling of Spam Scripts

This featureopen in new window will automatically chmod 000, thereby disabling, scripts that have exceeded email limits via PHP's mail() function. There is also a hook scriptopen in new window for this function, which can be used to rename the spam script if so desired (useful for flagging spam scripts as malicious, or for preventing accidental re-enabling of spam scripts that haven't been removed when running commands to fix permissions en masse).

Multi-Server Setup

Supporting DNS, email, and accounts, the Multi-Server Setup feature offers scalability and centralized management by allowing multiple DA servers to communicate with one another. While mostly used for DNS clustering (zone transfer), it can also sync email accounts and user accounts.

IP Linking

The multi-IP system allows having a website on multiple IPs and the fine tuning of IPv6 to IPv4 relationships. Automatically add an IP to certain areas (Apache/DNS) based on the selection of another IP, seamlessly link LAN IPs to external IPs, and/or link IPv6 IPs to IPv4 IPs with this feature.

Customizations

Many users find that they need to customize these necessary features, and the extent to which that can be done varies greatly depending on what panel you use. You'll discover that DirectAdmin is immensely flexible in this area.

DirectAdmin Configuration Options

The directadmin.conf allows you to easily enable/disable numerous features. You can even configure the DirectAdmin GUI to run via whatever available ports (SSL and non-SSL) you want! Take a look at all of the directadmin.conf options here.

CustomBuild

CustomBuild was named aptly so because it allows one to customize the versions of software installations, flags used at compile time so that one can include custom modules and settings with PHP and Apache, for example, custom hook scripts to run with CB after a certain software upgrade, and more. See the extent to which CustomBuild facilitates customizations here.

Control Panel Skin Customizations

Advanced evolution skin customization, which includes not only colors but also full sectioning, custom icons and custom URLs to any resource. The skin comes including Light and Dark modes out of the box. Custom scriptingopen in new window is even supported in the skin templates! You can customize the login page and have custom per reseller/user widgets.

Custom Package/Domain Items

The custom package and custom domain items allow you to customize packages and domains. Linking custom package items to hook scripts, you can perform certain tasks for certain packages only. For example, let's say you wanted a certain feature available on one package only, then you'd use this feature to accomplish that. Let's say you wanted to have an option available to display a checkbox for "In Active Development" when creating a domain. You could link this to a hook script that would then have a custom "Coming Soon!" index.html page placed in the site's docroot, replacing the index.html put in place by DirectAdmin. You wouldn't want to do this for all domains, though, because of production domains that you may migrate in. That is just one example of how you could use this feature. The custom package/domain items offer a higher level of customization on a per package/per domain basis.

never_commands

The featureopen in new window allows you to add any CMD_ to this variable, colon separated, so it can never be used. For example, if you want to fully prevent the creation of any new Admin account, you can add this to the directadmin.conf:

never_commands=CMD_ACCOUNT_ADMIN:CMD_API_ACCOUNT_ADMIN

This is similar to the per user commands.allow and commands.deny files, but never_commands is a global setting applicable to all users on the server.

commands.allow and commands.deny

The commands.allow and commands.deny files let you specify which commands you wish to allow and/or deny for a User. Use these to limit access to certain features, or grant access to only certain features on a per-User basis. For example, you could prevent a user's access to the API by adding CMD_API* commands to commands.deny for that user.

Custom Templates

You can customize the any of the templatesopen in new window that DirectAdmin uses, located under the directory /usr/local/directadmin/data/templates. These include DNS, Vhost, user notifications, and many other templates. These templates are tokenized (exampleopen in new window), meaning that variables are used, which permit a staggering degree of flexibility. Custom scripting is even allowed in the templates! For example, see thisopen in new window and this. For anything you wish to customize with DirectAdmin, you would just copy the file to the appropriate custom directory and make your changes to the file there. It's that easy!

DirectAdmin permits the use of their documentation via your URI.

You don't have to worry about spending the time, effort and money to provide your clients with general documentation for this panel's GUI. The documentation is available for licensed users to use under their own domain! The documentation available is served via https://www.site-helper.com/evo/sitehelper.phpopen in new window, but you can duplicate the content under your documentation URI, then change the URIs shown via the help buttons within the DirectAdmin panel. The help button URIs are controlled by user_helper, reseller_helper, and admin_helper in the DA configuration (/usr/local/directadmin/conf/directadmin.conf). Now, when users click the help buttons, they'll be directed to DA documentation loading under your domain!

Updates via CustomBuild

CustomBuild handles the software installations, removals, and updates for DirectAdmin. CustomBuild is unique to DirectAdmin alone and builds software from source, which allows it to support the latest software and versions as well as permit the highest degree of customization by allowing one to specify alternative versions to install (downloading your own even faster than it's added to the repos), custom compilation flags, and more. The only downsides are that it takes some time to build and can consume some CPU. However, being the first to run a highly anticipated software/feature makes it quite worthwhile.

An Internal Ticketing System, a Messaging System, Demo mode, and more to support reselling

Stellar accommodations are available for reseller hosting, including demoopen in new window mode for attracting new clients, an internal ticketing systemopen in new window for managing client issues, and a message systemopen in new window for communicating with all users (notifications about upcoming upgrades, for example). Resellers can have their own nameservers, their own IPs, and more.

The following describe features that are useful for those who resell hosting and have root access, so the term 'reseller' in the following does not describe the "Reseller" access level, but rather one who resells hosting.

Users, resellers, and domains can also be customized via user.conf, reseller.conf, and domain.conf files, respectively, which allows a reseller with root access to adapt and customize accordingly for each user/reseller/domain as their needs evolve. These files, which require root access to edit, are located under /usr/local/directadmin/data/users/(both the user.conf and the reseller.conf) and /usr/local/directadmin/data/users/<USERNAME>/domains/,and allow one to enable/disable certain features on a per-user/per-reseller/per-domain basis.

A nifty tool for resellers with root access is the login hash generatoropen in new window. You can log in as the root user, and generate a login URL for your users. Since this is based off of login keys, you can control what IPs can use it, how long and how many uses it is valid for, and what commands are allowed. This would allow you to configure passwordless root SSH access to the server, but also be able to generate a login URL so that you can log into your users' DirectAdmin GUIs without the need to inquire about or reset their passwords.

The option to combine all access levels for a single user server

Some clients may not be interested in reseller hosting and only need to run a single busy site on their server via a single user. DA accommodates this as well by eliminating the need to toggle between admin/reseller/user access levels. DirectAdmin permits one to combine all access levels into a single interface, allowing one to access all features from within one page. Select the checkbox "Merge Access Levels" to use this feature.

Multiple users with admin privileges

DirectAdmin allows you to create multiple Admin usersopen in new window. This way, if you have multiple individuals trusted to administer the server, you can track who logged in and made what changes since they can have their own unique login with admin privileges as opposed to having multiple trusted individuals sharing a single login.

Common Must-have features

Some baseline "Must-Have" features for any modern control panel include:

  • Server users (including quotas, packages and limits, access permissions)
  • Domain Name System
  • Web Service (a webserver with MultiPHP support and SSL certificates)
  • Database Service
  • E-Mail Service (including mailboxes themselves, aliases, forwarders)
  • Spam protection
  • Antivirus protection
  • Statistics and logs
  • Backups/Restorations
  • Service Monitoring
  • An API, hook scripts, plugins and widgets
  • Demo mode

DirectAdmin exceeds these minimum requirements with the following industry-leading software implementations:

Note that this list is not anywhere near completely inclusive of the features offered by DirectAdmin. DA brings so much more than this to the table as your hosting panel provider.

You may have noticed that some of the features listed above may include implementations that are unique to DA, such as BFM (their own Bruteforce Monitor).

Why DirectAdmin Will Always Be Unique

This is a quick look at the what makes DirectAdmin unique from a non-technical perspective. So, what is it that has allowed DirectAdmin to be unique thus far?

Because the company is comprised of people who truly love hosting, software, innovation, development, and the community... that's why.

It isn't hard to see this for yourself by perusing the forums. Whether it's smtalk posting custom written code in response to an issue a client has, or John pushing a fix to a bug discovered just an hour before, it's evident that these are committed people that love what they do.

This is also why DirectAdmin will always be unique. While other panels seem to be driven by the bottom dollar, DirectAdmin remains motivated by a passion for providing great software. While DirectAdmin cannot promise that there will never be a price increase simply due to the way business works, we can promise that we'll always do our best as your panel provider and do so at a rate within reason.
