System Management: Minibus

A new component, the Minibus, has been introduced under the hood. This ensures that system tasks only run in parallel when doing so is possible without conflicts. It is a locking system with batch processing. This has become necessary because an increasing number of Docker containers can be active on a single system. It is important that they are started in a specific order and cannot interfere with other processes during startup.

Two-Factor Authentication: Error Displaying 2FA QR Code

When importing a 2FA secret key in the File Export > Web Server menu, the QR code could not be displayed after unchecking the “Local User” box, entering a username, and generating a random key. This issue has been resolved, so the QR code is now generated and displayed correctly.

Additional Software: Bitdefender - Proxy for Updates

Updates to the virus signatures (patterns) of the Bitdefender virus and spam filter will continue to be performed according to a scheduled cycle. Pattern updates can now be performed using an HTTP proxy through the implementation of a new Bitdefender SDK.

Notes

Additional software: Bitdefender - pattern update after commissioning

After starting up the Collax Antivirus powered by Bitdefender module, it may take a few minutes for the current virus patterns to be downloaded. If you click on Update Bitdefender in the virus scanner form during this time, you will receive an error message “Error connecting to server at /opt/lib/bitdefender//bdamsocket: -3”, because the background process has not yet been fully executed.

GUI: Sporadic hangs during running jobs

The progress of configuration jobs is displayed in the top right-hand corner of the web administration. In the case of extensive changes in the network area, especially with country locks (geo-ip), it can happen in rare cases that the job display hangs during activation. As of release 7.2.28, you will now receive the message “Network connection has been interrupted: Messages may be lost until the connection can be re-established.” informs you about such situations.

VPN: Fix for IKEv2 with Microsoft Windows crashes after 7.6 hours

VPN connections with IKEv2 and the on-board tools of Microsoft Windows are interrupted after interrupted after exactly 7.6 hours. The error occurs because Microsoft Windows proposes different algorithms during the IKE re-encryption than during the first connection. The problem can be solved with a registry fix by the value “NegotiateDH2048_AES256” under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\Parameters to 1 is set.

Under the following link you will find a REG file (registry entry) that adds the registry key. Collax accepts no liability for system errors resulting from this.
