Hello,

I have followed the tutorial till the end, the ports are opened and forwarded 
to the openmeeting server, the cisco ASA is the entry point of the datacenter 
and I cannot directly manage it, I must ask the datacenter provider to do it 
(it is not wireless, it connected to my server “directly” by optical fiber)…

I have 5 external ip address, the one that I use is used (actually) for several 
services, let’s call the domain abc.com



Internet <----> cisco ASA <----> Abc.com forwarded do DMZ1 <----> firewall port 
443 <----> service 1

                                                                                
                                     <----> firewall port 5443 and other port 
as described in the doc <----> openmeetings/coturn

When entering to the meeting room and starting cam and/or mic, I have the error 
below :

Failed to start broadcast: Object 
'35699e5c-f2d5-45bd-b50f-b02f66b5fe27_kurento.MediaPipeline' not found 
(Code:40101, Type:null, Data: {"type":"MEDIA_OBJECT_NOT_FOUND"})

Directly on the server, I test the kurento server websocket avability on the 
openmeetings server and it is OK  :

curl -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" -H "Host: 
127.0.0.1:8888" -H "Origin: 127.0.0.1" http://127.0.0.1:8888/kurento

HTTP/1.1 500 Internal Server Error

Server: WebSocket++/0.7.0



I have the same result if I attack the server directly without passing by the 
firewall, so in my understanding of openmeetings architecture it is the “coturn 
server” wich doesn’t act properly…

PS : in the configuration step of 
/opt/open504/webapps/openmeetings/WEB-INF/classes/applicationContext.xml I must 
fill p:turnUrl= with the external ip of the server so I put the public ip of my 
domain (1.1.1.1 for example), so I have :

<!-- Kurento -->

        <bean id="kurentoHandler" 
class="org.apache.openmeetings.core.remote.KurentoHandler" init-method="init" 
destroy-method="destroy"

                        p:kurentoWsUrl="ws://127.0.0.1:8888/kurento"

                        p:checkTimeout="10000"

                        p:watchThreadCount="10"

                        p:turnUrl="1.1.1.1:3478"

                        p:turnUser="kurento:PasswordKurento"

                        
p:turnSecret="c3fa61a921f7589249529ecad861b5c5bdae1a5b4f720eb79b6459ca908c87a7"

                        p:turnMode="rest"

                        p:turnTtl="60"

                        p:objCheckTimeout="200"

                        p:flowoutTimeout="5"

                        />

My kurento server version is 6.13.0

Hello,

Just follow the tutorial till now he end. Open said ports on firewall as well 
as your router. It will start working.

Is Cisco your accesspoint? Is it wireless?

If so that could be a problem with the server. Have you done DCHP address 
registration of your wifi card on the cisco?



Thanks.

Hello,

I haven’t fully understood where in my infrastructure I must install the Coturn 
server :

Openmeetings and coturn server (DMZ) <------> firewall (2nd NAT) <------> Cisco 
ASA (provider, 1rst NAT) <------> internet

I have install and configured openmeetings 5.0 M4 has described in the doc, 
configure my ssl key for my domain but webrtc and mic doesn’t work so I suspect 
that the kurento server doesn’t fully work with the cotrun server (according to 
the doc I have install the cortun server on the same server as the openmeetings 
and use the internet ip of my domain for configuration)…

The whiteboard functions are OK but web conf doesn’t work at all…

Thank’ for advices..

Best regards

Alain
