Knox E-FOTA On-Premises 23.12 release notes

Last updated December 14th, 2023

Support for Red Hat Enterprise Linux 9.2

Starting with the 23.12 release, Knox E-FOTA On-Premises now supports Red Hat Enterprise Linux 9.2 in addition to 8.4.

Support for Red Hat Enterprise Linux High Availability Add-on

Knox E-FOTA On-Premises previously only supported high availability technologies on Ubuntu. Additionally, high availability technologies were only supported with an application layer through dfm-core and dfm-console.

Starting with the 23.12 release, Red Hat Enterprise Linux High Availability Add-on is now fully supported with HAProxy, DB, and minIO storage servers. The full-stack High Availability Add-on is also supported.

Improvements to polling cycles of firmware versions

Before the 23.12 release, you had to wait for the next polling cycle — configured to either every hour or every 24 hours — before the device could proceed to the next step in a campaign.

To help you deploy firmware at a shorter cadence, the waiting time between steps can now be configured. Updates now shorten previously established polling cycles and instead update whenever available.

During sequential updates, devices also reboot and update accordingly. For the first installation of a sequential update, a firmware installation notice displays for 30 seconds by default. The waiting time can be adjusted to any value from 1 to 7200 seconds in the dfm_conf.json file.

Tooltip for invalid firmware

Previously, there was no way to verify whether enrolled devices had official Samsung firmware installed.

Knox E-FOTA On-Premises 23.12 can now detect unofficial firmware versions. If the console detects unofficial firmware, a warning icon displays beside the firmware version, and a tooltip shows when you hover over the corresponding firmware version on the Devices page.

Default server URL in the client app

From Knox E-FOTA On-Premises 23.12 onward, the client app can now work with a predefined server URL. If there’s no efota_config file configured after installation, the Knox E-FOTA On-Premises agent app sets a default server URL —

If you uninstall the agent app from a device and reinstall it afterward, any custom server URLs aren’t kept. However, the agent app will still work with the default server URL.

If you’ve configured an efota_config file, the server URL specified takes precedence over the default server URL.

See Create a configuration file for more information.
