to kurento

Just a quick note before we get started here. I have removed all references to IP addresses, usernames, passwords and even some ports in the post for security reasons so if you see something that says "hostname" or "ipaddress" then this is why.

The installation of the server was pretty simple. I did it manually as I wanted to use my own stun and turn servers instead of the coturn stuff on their AWS template.

My server is installed on AWS but I won't be able to answer many questions about that process as my IT guy set up the server and installed everything for me. Follow these

instructions to install - Installation Documentation.

One thing to note is that if you run this command:

sudo netstat -tupan | grep kurento

and you don't see anything come back then check your logs to make sure that the KMS started correctly. Now onto other issues and solutions...

The first issue was this:

kurento-client.js:54826 WebSocket connection to 'wss://hostname:8433/kurento' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED
ws @ kurento-client.js:54826
index.js:70 reconnect to server 0 100 undefined
kurento-client.js:54826 WebSocket connection to 'wss://hostname:8433/kurento' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED
ws @ kurento-client.js:54826
WebsocketStream @ kurento-client.js:54716
WebsocketStream @ kurento-client.js:54699
(anonymous) @ kurento-client.js:47551
attempt @ kurento-client.js:47455
EventEmitter.emit @ kurento-client.js:19730
Backoff.onBackoff_ @ kurento-client.js:4307
index.js:70 reconnect to server 1 100 undefined

I found that this issue can be caused by many things. The first of which is that you don't have the correct port open on the KMS 8433.

The biggest thing that caused me issues is not knowing how to combine the .crt .csr .key files into a .pem if your certificate authority doesn't provide you with one. With

help from my IT guy we figure out that the KMS REQUIRES the .pem file to be formatted like this:

chainfile + cert file + key file = my_cert.pem

If this step isn't done correctly then you may get errors like this in your logs:

Error while setting up tls use_private_key_file: no start line
Error while setting up tls use_private_key_file: key values mismatch

Also see Kurento Websocket Connection Failed for some more information about Kurento and certificates.

Also be sure to see Kurento Securing Apps Documentation for securing client side applications. If you are using the JavaScript client like I am then

make sure that it is being run as HTTPS otherwise WebRTC doesn't like to work properly.

Once you have made sure the port is open and your .pem file is assembled correctly; another reason you can get this error is if the KMS does not have permissions to either the folder that the .pem file is in or if it doesn't have permissions to the .pem file itself. So make sure that wherever you put your .pem cert file that you give the KMS permissions to access that file.

This is what your kurento.conf.json file should look like if you are setting it up on a remote server:

{
  "mediaServer" : {
    "resources": {
    //  //Resources usage limit for raising an exception when an object creation is attempted
    //  "exceptionLimit": "0.8",
    //  // Resources usage limit for restarting the server when no objects are alive
    //  "killLimit": "0.7",
        // Garbage collector period in seconds
        "garbageCollectorPeriod": 240
    },
    "net" : {
      "websocket": {
        "port": 8888,
        "secure": {
          "port": 8433,
          "certificate": "my_cert.pem",
          "password": ""
        },
        //"registrar": {
        //  "address": "ws://localhost:9090",
        //  "localAddress": "localhost"
        //},
        "path": "kurento",
        "threads": 10
      }
    }
  }
}

One of the biggest things that helped me determine some of these issues was looking at the log files. They are located at /var/log/kurento-media-server. Just be weary that

that when you are looking at the logs if you restart your KMS that it will generate an ENTIRELY new log file so if you end up restarting the service and you aren't getting any logs

then that is why.

I hope this helps others out as I have literally spent 2 days weeding through the internet and log files trying to understand why the Tutorials wouldn't connect to a remote media server.

I still haven't gotten the tutorial to fully work with a remote KMS and external Stun and Turn Servers. The logs tell me the loopback connects but nothing shows up.

I have my WebRtcEndpoint.conf.ini configured like this:

; Only IP address are supported, not domain names for addresses
; You have to find a valid stun server. You can check if it works
; usin this tool:
;   http://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/
stunServerAddress=<stun server ip>
stunServerPort=<stun port>


; turnURL gives the necessary info to configure TURN for WebRTC.
;    'address' must be an IP (not a domain).
;    'transport' is optional (UDP by default).
turnURL=username:password@turnip:turnport


;pemCertificate is deprecated. Please use pemCertificateRSA instead
;pemCertificate=<path>
;pemCertificateRSA=<path>
;pemCertificateECDSA=<path>

These are the logs I am getting from the KMS when I click start on a tutorial:

As you see it shows that Loopback has been established but all I get is a continuous loading screen for the "Remote Stream"

I'm going to keep working through this and hopefully I can get this to work. If anyone has any suggestions on how to fix this last issue that would be extremely welcome. I hope that

all of my other information can help others struggling with the same situations I have been.

to kurento

Also when I run these commands this is what I get back. I assume this is correct? it looks almost identical to the documentation.

ps -ef | grep kurento-media-server

sudo netstat -tupan | grep kurento
