Notes

Additional software: Bitdefender - Proxy for updates

The virus pattern updates are carried out according to a set cycle. For the pattern update of the Bitdefender virus and spam filter, the use of an http proxy is currently not possible.

Additional software: Bitdefender - pattern update after start-up

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

GUI: Running Jobs Hang Sporadically

The progress of the configuration jobs is displayed in the upper right corner of the web administration. In the case of extensive changes in the area network, especially in the area of country locks (geo-ip), the job display of the activation can hang in rare cases and lead to a timeout. For updates up to release 7.2.14, the message “ipset v7.11: Set cannot be destroyed: it is in use by a kernel component” also appeared. which could lead to uncertainty. The changes are all correctly applied and this is only a cosmetic problem. Until the error is completely fixed, you can help yourself by reloading the browser window.

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

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

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