Cool VL Viewer forum

As far as I know, I have no rules at all. Certainly I didn't put any myself:

Try with Wireshark: it should give you the necessary clues for what is going wrong...

I failed to understand how Wireshark works, to my shame.

However, looking through the web, I found this comment. I tried it, toggled voice and… it connected. How? Why? What does one have to do with the other? Will I have problems seeing and listening media if "Media and stream audio filtering" is off?

Err... It got strictly nothing to do with voice.

The media filter only applies to media (parcel media, parcel music, media on a prim), not to voice (which is not even connecting to the server via the viewer, but instead via SLVoice, itself having no relation whatsoever with the media filter code) !

This however could be some weird interaction with your DNS stack (faulty/buggy DNS cache daemon): try re-enabling the filter and disabling "Lookup IP address for filtered domains". Maybe this could cause your DNS cache to stay stuck, somehow...

No, but you loose the filter protection...

I did it and voice connects. What do I lose by disabling "Lookup IP address for filtered domains"? How important is it?

What DNS cache/proxy are you using ? Avahi, dnsmasq, something else ?

You could try and right out disable that cache/proxy (this is totally dispensable), and see how it fares then.

Without it, the media filter will only work on domain names: if the domain is changed (e.g. to evade such filters) but still points on the same server, the filter won't detect it.

I do not. Avahi is installed, as dependency of many things, but I never enabled the service. I'm not a network security person. I do office (xelatex etc mostly), secondlife, movies etc and, since 2020, conferences (zoom, jitsi etc).


I'll research further into that.

Here again Wireshark would tell you what is happening (just watch the DNS requests to resolve the voice server name).

You could also short-circuit the DNS for the voice server, by adding an appropriate entry in /etc/hosts
