Easy way to test TURN server
I'm looking at this site, which is supposed to be table to test a TURN server (according this this answer).
plugin.temasys.com.sg/demo/samples/web/content/peerconnection/trickle-ice/index.html
I put in my server info, but couldn't find anything to determine if the server is working. The ice candidates section looks the same even its there's no server chosen.
My TURN server is installed on Amazon EC2. I followed the install instructions from the coturn repository here:
github.com/coturn/coturn/blob/master/INSTALL
The following is what I get in my server when I do the command to start the TURN server, from here:
RFC 3489/5389/5766/5780/6062/6156 STUN/TURN Server
Version Coturn-4.2.1.2 'Monza'
0:
Max number of open files/sockets allowed for this process: 4096
0:
Due to the open files/sockets limitation,
max supported number of TURN Sessions possible is: 2000 (approximately)

It appears to be working, but how do I know? I apologize for my ignorance, I've been reading so many docs on this I can't keep track of it all.
EDIT: Well something is happening :)
I'm receiving these on my turn server now whenever use the site mentioned above:
64: ERROR: check_stun_auth: Cannot find credentials of user <ubuntu>
64: session 000000000000000004: realm <realm> user <ubuntu>: incoming packet message processed, error 401: Unauthorised
EDIT 2: I removed the ubuntu portion, and am now receiving what appears to be successful responses. Still don't really know what it means, but it's a start :)

Answer
If you have a test app with WebRTC.
You can force the TURN on Firefox.
Tab: about:config
Search: media.peerconnection.ice.relay_only
Set it to true
At this moment Firefox only use TURN relay.
