OX Drive
In OX App Suite, Open-Xchange provides a cloud storage called OX Drive. It provides file- and folder synchronization across multiple devices in the simplest way for the end user, fully optimized for each device type. This article explains how to set up the server-side components for OX Drive, as well as details about the app setup.
Key features
- Native Apps for Windows, Mac OS, iOS and Android
- Easy and attractive upsell properties (e.g. Upsell based on Quota limitations)
- Apps are specially designed for the devices they run on taking into account limitations such as battery life, screen limitations, bandwidth etc.
- Controlled synchronization of files across devices
- Storage management (e.g. quota control, upload limits)
- Connection type recognition and adaptation (e.g. Wi-Fi, cell network)
Availability
OX Drive is a combination of two components:
- OX Drive in OX App Suite
- OX Drive Apps (optional native apps for synchronization)
OX Drive is available as native app for the following operating systems:
- OX Drive for Windows
- OX Drive for Mac OS
- OX Drive for iOS
- OX Drive for Android
Requirements
You will find the requirements under OX Drive App and Platform Requirements
Server-side Installation and Configuration
This chapter describes how the backend components of OX Drive are installed and configured on the server.
Prerequisites
- Open-Xchange Server v7.4.2 and above (open-xchange-core)
- Grizzly HTTP connector (open-xchange-grizzly), see AppSuite:Grizzly for details, with Comet support enabled in grizzly.properties
- Valid Push-Certificates / API keys for cloud-based notifications, see configuration below
- Enabled Hazelcast for inter-OX-communication, see AppSuite:Running_a_cluster for details
Available packages
Open-Xchange Drive is available with the following backend packages:
- open-xchange-drive - The main server components for OX Drive
- open-xchange-drive-comet - Provides the Push interface via long-polling for the desktop apps
- open-xchange-drive-help-* - Online help in various languages for the OX Drive applications (these were called open-xchange-appsuite-help-drive-* in versions earlier than Open-Xchange Server v7.6.2)
- open-xchange-drive-restricted - Restricted components, including prerequisites for cloud-based push notifications
Installation on the server varies depending on the underlying distribution, details are available in the following chapters.
OX Drive for Windows
Additionally OX Drive for Windows can be provided to users by installing additional packages. However there are significant differences between 7.8.0 and earlier releases and 7.8.1 and later ones:
7.8.1 and later
With OX App Suite 7.8.1 and OX Drive for Windows 2.0.0, the app is able to update itself and can be downloaded from the Web UI directly via the App Onboarding Wizard. Therefore the wizard must be installed and configured for OX Drive users. Besides the client onboarding feature you need the following packages:
- open-xchange-drive-client-windows - The main server component to provide the app
- open-xchange-drive-client-windows-generic - The package providing the final binary files to be installed on users machines.
To make the app download available via the app onboarding wizard, you need to enable the according scenario. Edit /opt/open-xchange/etc/client-onboarding-scenarios.yml and get to the drivewindowsclientinstall section, where you have to set the enabled property to true.
Please note that there still exists a compatibility layer between the old Updater-based approach and the new direct install and self-update one. If you start providing OX Drive for Windows with 7.8.1 or later you MAY decide to enable that compatibility by installing open-xchange-updater-drive, however we advice not to do so. If you already provided OX Drive for Windows with 7.8.0 or earlier, you MUST install this package and further provide the Updater. Otherwise the apps out there will not be able to be updated to the 2.0.0 version, which is then self-update capable.
Custom branded apps
OX Drive for Windows can be purchased with a custom theming. In such cases, the according binary files need to be installed on the middleware servers. Instead of the open-xchange-drive-client-windows-generic package, a package containing the branded binaries will be provided as open-xchange-drive-client-windows-<brand-name> and needs to be installed. You MUST then set the property com.openexchange.drive.update.branding in /opt/open-xchange/etc/drive-client-windows.properties to <brand-name> accordingly.
It is also possible to provide multiple brands of the app via the same OX App Suite deployment, multiple open-xchange-drive-client-windows-<brand-name> packages can be installed in parallel. Which brand is available for a certain user is determined by the com.openexchange.drive.update.branding property, which can be overwritten via Config Cascade therefore.
App brands can be managed via command line tools. The tool /opt/open-xchange/sbin/listdriveclients lists all installed brands. After updating a certain brand by installing a newer package version or installing an additional one, no server restart is necessary. Instead /opt/open-xchange/sbin/reloaddriveclients can be executed to refresh the internal server state.

OX Server Edition / App Suite for UCS
If you have purchased the OX Server Edition / App Suite for UCS, the OX Drive is part of the offering and after the installation/update available. The necessary package for push, is available with a valid license and can be installed via the Univention App Center.
- The new license is already registered at the LDB after purchase.
- Log on at the Univention Management Console (UMC)
- Make sure, that the correct LDB account has been selected in the UMC module "OX License Management"
- Click on "App Center" at the UMC und switch to the tab "Repository Settings"
- Within the component list, select "Open-Xchange Drive" and press the "Install" button
Configuration
The following gives an overview about the most important settings to enable file synchronization via OX Drive, especially when it comes to real-time Push notifications for the apps.
All settings regarding the OX Drive backend component are located in the configuration file drive.properties. The default configuration should be sufficient for a basic "up-and-running" setup (with the exception of defining the Push certificates and API keys for cloud-based app notifications, see next chapters). Please refer to the inline documentation of the configuration file for more advanced options.
OX App Suite v7.10.2 and later
With OX App Suite v7.10.2, most properties located in configuration file drive.properties are now config-cascade aware. Therefore all settings can be set per user, per contextSet or per context. If there is no configuration per user, per contextSet or per context, the configuration in drive.properties will still be used as server-wide fallback.
When installing 7.10.2 from scratch, the configuration file drive.properties is no longer shipped, as the default values are used. For more details, find an overview of configurable settings here.
If no Push certificates and API keys are defined but cloud-based app notifications are enabled, the Push certificates and API keys from package open-xchange-drive-restricted are used as fallback, if this package is installed.
Push via Firebase Cloud Messaging (FCM)
The OX Drive application for Android devices is able to receive Push notifications from the Open-Xchange Server via Firebase Cloud Messaging (FCM). To issue those Push messages, the backend needs to be provided with a suitable API key for the corresponding Android app application. The API key is included in the restricted components installation package open-xchange-drive-restricted for the "vanilla" Android app. Alternatively, the key can be specified directly in the drive.properties configuration file:
# Specifies the API key of the server application. Required if # "com.openexchange.drive.events.gcm.enabled" is "true" and the package # containing the restricted drive components is not installed. com.openexchange.drive.events.gcm.key=
Push via FCM can be enabled via:
# Enables or disables push event notifications to apps using the Google # Firebase Cloud Messaging (FCM) service. This requires a valid configuration for the # FCM API key, see options below. Defaults to "false". com.openexchange.drive.events.gcm.enabled=true
Please note that push via FCM needs to be enabled explicitly - also if open-xchange-drive-restricted is installed.
Push via Apple Push Notification service (APNs)
The OX Drive application for iOS and Mac OS devices is able to receive Push notifications from the Open-Xchange Server via Apple Push Notification service (APNs). To issue those Push messages, the backend needs to be provided with a suitable keystore container file (PKCS #12) containing the APNs certificate and keys. Note that the Mac OS desktop app and the iOS mobile app are served separately with different certificates, so that both needs to be configured independently. The required certificates are already included in the restricted components installation package open-xchange-drive-restricted for the "vanilla" iOS and Mac OS applications. Therefore no additional configuration is needed. Alternatively, an external certificate can be specified directly in the drive.properties configuration file (the following only shows the setup for iOS). First, the path to the PKCS #12 container file needs to be specified at:
# Specifies the path to the local keystore file (PKCS #12) containing the APNS # certificate and keys for the iOS application, e.g. # "/opt/open-xchange/etc/drive-apns.p12". Required if # "com.openexchange.drive.events.apn.enabled" is "true" and the package # containing the restricted drive components is not installed. com.openexchange.drive.events.apn.ios.keystore=
This file is opened by the backend using the password as supplied via:
# Specifies the password used when creating the referenced keystore containing # the certificate of the iOS application. Note that blank or null passwords # are in violation of the PKCS #12 specifications. Required if # "com.openexchange.drive.events.apn.enabled" is "true" and the package # containing the restricted drive components is not installed. com.openexchange.drive.events.apn.ios.password=
Configuration also allows to switch between development and production environments, however, this setting should be true normally:
# Indicates which APNS service is used when sending push notifications to iOS # devices. A value of "true" will use the production service, a value of # "false" the sandbox service. Defaults to "true". com.openexchange.drive.events.apn.ios.production=true
The OX backend contacts the APNs servers from time to time to get informed about apps no longer reachable apps where the applications was uninstalled. The interval can be defined with the following setting:
# Configures the interval between queries to the APN feedback service for the # subscribed iOS devices. The value can be defined using units of measurement: # "D" (=days), "W" (=weeks) and "H" (=hours). Defaults to "1D" (one day). # Leaving this parameter empty disables the feedback queries on this node. # Since each received feedback is processed cluster-wide, only one node in the # cluster should be enabled here. com.openexchange.drive.events.apn.ios.feedbackQueryInterval=1D
Please note that if you have multiple backend nodes in the cluster, it's recommended that only one node is configured to contact the feedback query service. Finally, Push notifications via APN for iOS can be enabled via:
# Enables or disables push event notifications to apps using the Apple Push # Notification service (APNS) for Mac OS devices. This requires a valid # configuration for the APNS certificate and keys, see either options below, # or install the restricted components packages for drive. Defaults to # "false". com.openexchange.drive.events.apn.ios.enabled=false
As stated above, configuration for Push notifications via APN for the Mac OS desktop application is configured similarly, the relevant options are prefixed with com.openexchange.drive.events.apn.macos. Please also note that push via APNS needs to be enabled explicitly - also if open-xchange-drive-restricted is installed.
Further Configuration
- The backend component of OX Drive supplies the apps with various hyperlinks, e.g. deep-links to files and folders in the groupware webinterface or an URL to the online help. In order to point to the suitable web interface, please ensure that the correct UI web path is configured via com.openexchange.UIWebPath located in server.properties.
- As already mentioned above, the backend relies on the Comet component of the Grizzly http connector for sending push notifications to the desktop apps. Therefore, com.openexchange.http.grizzly.hasCometEnabled needs to be set to true in grizzly.properties.
Enabling OX Drive for Users
OX Drive is enabled for all users that have the capability com.openexchange.capability.drive. Please note that users need to have the infostore permission set to use drive. So the users that have drive enabled must be a subset of those users with infostore permission. Since 7.6.0 we enforce this via the default configuration. You can also enable this cabaility globally with the following setting in the drive.properties configuration file:
# Enables or disables the "drive" module capability globally. The capability # can also be set more fine-grained via config cascade. Per default it is only # enabled for users that have the "infostore" permission set. This is configured # in /opt/open-xchange/etc/contextSets/drive.yml. com.openexchange.capability.drive=false
More details about capabilities can be found at AppSuite:Capabilities. Furthermore, this capability can be defined in a more granular way using the Config Cascade as described at ConfigCascade.
Installation of the Apps
Installation of Mac OS X Desktop App
The OX Drive for Mac OS X is provided via the Apple App Store:
Enabling the Finder Extension on Mac OS X
In order to be able to use the Finder to open documents or share objects on a Mac OS X workstation, you need to enable the Drive Finder Extension.
How to enable the Drive Finder Extension on a Mac OS X workstation:
- Open the System Preferences. In the System Preferences window, select Extensions.
- In the Extensions window, select Finder. Enable Drive Finder Extension.
Installation of Windows Desktop App
See OX Drive for Windows.
Installation of Mobile Apps
The OX Drive App is available via the different App Stores:
App Configuration and Deployment
The user needs to enter the server URL and provide his username and password to log in. Afterwards, app-specific synchronisation settings may be configured. More information is available in the online documentation which is accessible from within the app.
After the initial synchronization is completed, all further changes are synchronized instantly across all devices.
Note: Version v7.10.3 of the OX App Suite introduced optional multifactor authentication, see https://documentation.open-xchange.com/7.10.3/middleware/security_and_encryption/multifactor_authentication.html. The OX Drive apps do not support this yet. If activated on the server, you will not be able to connect with the apps anymore.
