Changelog: Naksu 2 Server Management Tool

Version 5.4.1 (2026-04-17)

Changes to the Naksu 2 application/underlying tool ytl-linux-digabi2-examnet:

Ensure certificate can always be retrieved when using exam network mode, even if KTP is using another exam network KTP as DNS, which would previously prevent certificate retrieval
Further fixes to bugs that prevent uploading logs to Abitti support; log files are now copied to a temporary directory for uploading to avoid interference

Changes to the Naksu 2 application/underlying tool ytl-linux-digabi2-examnet:

A new, more reliable mechanism for the custom server name feature has been added under the hood; this mechanism is much less likely to be disrupted by variances in network and client device configuration posture
- For this change to take effect, currently existing network settings must be saved again
Updated open network certificate retrieval system for better speed and reliability; the same IP address and same API key will now receive the same certificate for as long as it is valid
Naksu will now bind the Abitti 2 server to listen only on the selected (internal) network device, not all network devices
Fixed an issue that would cause Naksu 2 to be unable to upload logs to Abitti support
Fixed a bug that caused the warning about an expiring certificate to be shown even though the certificate had already been renewed
When a network interface’s IP address changes, the selected network interface is reset

Changes to the Naksu 2 application:

Changes to the Naksu 2 application:

Fixed an issue where certificate download would fail due to incorrect file permissions
Fixed an issue which could potentially cause fetching network devices to hang in certain conditions
Updated instruction links to point to the correct pages in the reworked abitti.fi

Changes to Naksu 2 application:

Fixed an issue where the UI would display incorrect or outdated network interfaces when removing exam network settings
In exam network mode, the server certificate is automatically refreshed on server restart when certificate is expiring in the next 14 days
Fixed a localization issue that caused some buttons to show text in the previous language when language was switched
The old UI has been removed, along with the “Beta” menu

Changes to the Naksu 2 application:

New Naksu 2 UI is shown by default.
Dialogs are always correctly shown on top of all other elements. Dialogs can be closed with Esc button or by clicking outside of them.
Fixed an issue where sending logs to Abitti support would fail if a file could not be read, and where Naksu would try to upload partially synchronized server logs, causing this issue.

Changes to the underlying YTL Linux:

Fixed an issue where Windows clients were unable to resolve the correct IP address for server friendly names.

Changes to the Naksu 2 application:

Allow setting internal network device to one that does not have an IP address in exam network mode; this is common in Abitti exam networks that are set up entirely empty, without any DHCP servers etc.
Starting the server is now also allowed when exam network settings have been modified in the UI
Fixed a bug that prevented generating open network certificates if exam network settings had been created
If starting the server takes too long, a “Stop server” button will now be displayed after a certain time
Fixed an issue that caused button busy spinners to not render in the application
The application will now display a warning when the server certificate is about to expire within 14 days

Changes to the underlying tool ytl-linux-digabi2-examnet:

Correctly detect and stop exam network settings creation if certificate is invalid
Fixed an issue where a misconfigured exam network could not be reconfigured
Fixed an issue where exam network could not be configured when the certificate directory was missing
Fixed an issue where removing exam network configuration did not remove all relevant configurations, leaving the system in a partially broken state
