documentation questions

[streaps]

I have some questions that are not covered by the documentation:

Is port 9000 used for anything? (it shows up in netstat)

Do I need coturn or does kraken also work without a turnserver? https://github.com/MixinNetwork/kraken#quick-start doesn't mention a turnserver, but https://vec.io/posts/deploy-a-group-audio-conferencing-service does.

I'm running kraken inside a container with a local IP and and a reverse proxy on the public IP. Do I have to configure any additional port forwards? (UDP ports?)

[cedricfung]

9000 is for the default pprof endpoint for profiling. I should make it disabled by default and add an option to enable it.

TURN is not a requirement, but recommended for better connection.

I'm not familiar with container configurations, sorry.

I'm not familiar with container configurations, sorry.

I guess kraken is listening on some UDP port for the webrtc connection or how is the audio transmitted?

[cedricfung]

If you don't use turn, then you should open as many UDP ports as possible

[cedricfung]

I use turn server so that I could only open one port to the public, the the turn server connect with kraken via vpc

[streaps]

If you don't use turn, then you should open as many UDP ports as possible

I cannot forward all 65535 UDP ports to kraken. With other voip software you usually can configure a range of UDP ports. It's not clear which port range is used by kraken.

[cedricfung]

I will try to add some configurations for port range.

[streaps]

Thanks for the port range configuration commit. I'm still not sure how to use kraken and kraken.fm without a turn server.

I'm running kraken in an LXC container on a local IP, ports are forwarded from the public IP to the local IP. What should I put in TURNSERVER in kraken.fm/index.js or should I comment out iceServers and iceTransportPolicy?

I also don't know what the error message means:

Hi,

I am facing same issue while running the server and client on local.

Were you able to solve the issue?

[cedricfung]

To run the client and server in local, please do this modification in index.js

   const configuration = {
-    iceServers: [{
-      urls: TURNSERVER,
-      username: "webrtc",
-      credential: "turnpassword"
-    }],
-    iceTransportPolicy: 'relay',
+    iceTransportPolicy: 'all',

[streaps]

it's still not working for me.

I wonder if it has to do with the non-public IP that kraken is using. Is there a way to configure/set the public IP?

[cedricfung]

Maybe change the interface name in the configuration? I'm not familiar with container, maybe you could try something without container at first?

[streaps]

The interface name is correct (eth0). I just tested it without a container and it seems to work fine. I guess all it needs to work inside a container is a configuration option to set the IP address.

I'm running a webrtc proxy for Mumble and it works fine insider a container with NAT. https://github.com/Johni0702/mumble-web-proxy#firewalls-or-nat

[cedricfung]

Please try the new configuration.

looks good :). no errors in the log and audio works between mobile and desktop browser.
