coTURN unable to do a handshake in Mozilla Firefox

coTURN unable to do a handshake in Mozilla Firefox - udp

I have a web and standalone applications that use WebRTC.
I have my own coturn server on Amazon EC2. I configure everything based on that article (maybe it was a mistake?). I test my apps with this stun/turn server and everything works just fine for Chrome, Edge, Safari, but does not work for Mozilla Firefox (Offer and Answer were generated). I received the following error in a console:
ICE failed, your TURN server appears to be broken, see about:webrtc for more details
I assume that I misconfigure something, so this is why it doesn't work.
EC2 machine I used:
2x private IP,
2x public IP (Elastic IP),
tier: T2.micro,
UDP/TCP ports are open.
Configuration of coturn (/etc/turnserver.conf file):
listening-ip=0.0.0.0
external-ip={publicIP}:{privateIP}
external-port=3478
fingerprint
realm={publicIP}
lt-cred-mech
user={username}:{password}
log-file=/var/tmp/turn.log
verbose
Stun/Turn server configuration in a code:
RTCConfiguration.Create([|
RTCIceServer.Create([|
"stun:{publicIP}:3478"
"turn:{publicIP}:3478"
|], {userName}, {password}, RTCIceCredentialType.Password)
|])
And the transport policy set to all.
And the whole turn.log for only this request from Mozilla:

Any tips what I possibly do wrong would be appreciated!

You should double-check your internal routes defined in AWS for an EC2 instance and some global one about inbound traffic.
Mozilla Firefox would be the only one that would fail to do the "handshake" if the stun/turn server is not available outside of the internal network.
Chrome, EDGE, Safari would work in such a situation and establish a P2P (srflx) connection.
In my situation, there was some additional definition of inbound traffic to all of the AWS instances, which were blocking the traffic to the stun/turn server. I realize that when I was trying to test the WebRTC from one computer (connected to a VPN) to another (not connected to a VPN) and it fails while doing a "handshake".

packer: ssh communicator ignores "ssh_port"

I am working on building a VirtualBox VM with type "virtualbox-iso" and OpenSUSE 42.3 as the guest OS.I am specifying host and port that the ssh communicator should use during the build but it looks like packer is ignoring the port specification.
I am overwriting the default settings for host and port in my "builders" section. This is an excerpt of my json file:
"builders": [
{
"type": "virtualbox-iso",
"communicator": "ssh",
"ssh_host": "192.168.1.5",
"ssh_port": "22",
"ssh_username": "some_user",
"ssh_password": "some_password",
"ssh_timeout": "20m",
"ssh_handshake_attempts": "1000",
Packer is unable to connect to the VM because packer is ignoring the port I am providing with "ssh_port".
This is the debug output (enabled with PACKER_LOG=1):

Is this expected behavior or am I doing something wrong?

This is because of how VirtualBox NAT networks work. From the host you can't reach the guest VM directly. Packer solves this by setting up port forwarding rule. A random port between ssh_host_port_min and ssh_host_port_max is forwarded to the guest VMs ssh_port.
If you want to turn this of set ssh_skip_nat_mapping to true, but then you have to ensure that you have a network setup where Packer can reach the guest.

It is because you are doing "22" instead of 22. The config is looking for an int, not a string.

Why my WebRTC connection doesn't works at some networks?

I've customized Apprtc project (android version).
assume we have four internet connection (from different network connections):
NetA -- NetB
NetC -- NetD
I can connect from NetA to NetB, but i can't connect from NetC to NetD!
I have set turn server and stun server but i don't know what is wrong.

EDIT :
Thanks to all. I found my problem is from my turn server. I can connect in any situation when using appr.tc ice servers (google turn servers). but i can't connect with my turn server. please check question about my turn server at this page :
Why my turn server doesn't work?

Take a look at this article Introduction to WebRTC protocols.
You need to set up STUN and TURN server, to pass the firewall. If peer is behind a firewall or a router, by connecting only to IP address you will hit router not the requested peer device. etc etc.

I would begin to test my TURN server if it is really working.
Disable direct links on your firewall (between NetC and NetD or just block the peer IP) to see if it is working via TURN. If not, then fix your TURN server or it's configuration.

Kurento RTSP to webRTC

Im a developping a Samsung Smart TV app with Samsung's TOAST and Caph-angular. I am on Windows 10.
When I call our server, I get an RSRP url encoded with H264 but, on smart TVs, RSRP is not supported. Then I have to "transform" the RSRP url to some webRTC one (I know very little about all this so sorry if the terms are incorrect).
I searched here and there and found Kurento which seems to be able to answer my needs.
Before trying Kurento within my app, I wanted to test it on a few demos.
I was able to test one2many example without any problem but I am having trouble running rtsp2webrtc demo.
I git cloned kms-windows and https://github.com/lulop-k/kurento-rtsp2webrtc and tried to run the demo but the player is not displaying anything.
1) I double-click kms-windows\bin\kurento-media-server
2) I launch http-server in kurento-rtsp2webrtc
3) I reach http://localhost:8080/, type my sample rtsp url (rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov) and click on "start"
No error seems to happen, see console logs:

Player playing ...
oniceconnectionstatechange -> connected
icegatheringstate -> complete
oniceconnectionstatechange -> completed
icegatheringstate -> complete
But the player does not display anything. I still see the spinner.
I tried adding a STUN server (not sure what it is or if I even need one, just saw this in docs or other stackoverflow issues) and it did not solve anything.
Could you please help me?
Did I do anything wrong or forget something?
And, in the future, when I want to implement this into my tv web app, will I only need to include kurento-client.js and kurento-utils.js files or will there be other things to take care of?
Thanks in advance

Stun server cannot traverse symmetric NAT's so for that purpose if your server is behind NAT then you should try using TURN server

if you Kurento server is behind the NAT - you need to use TURN server for it

Apache HTTP Server port doesn't respond

I'm forging a packet to start a TCP connection with port 80 (so I'm sending a TCP-SYN) and the HTTP Server does not respond at all.
I've ran netstat -natu during the all process and no change on the port 80 state:
Active Internet connections (servers and established)

The port is always on LISTEN state, and upon receiving a TCP-SYN it should change to SYN_RECV right?
If it helps, a Wireshark capture of the packet I send:
So I can't seem to see what the problem is.

Have you noticed that you're using tcp6 (mean IPv6) but trying to open up the session using IPv4?
I guess that's why it's not opening the session. Try to align to IPv4.

Apache Not Starting

I can't seem to start Apache 2.2 on Windows7 listening on ports 80 and 8443.
I get the following error:
(OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : make_sock: could not bind to address 0.0.0.0:8443 .
This error is usually caused by another app listening on the same port but I definitely don't have another application listening on port 8443.
I get this error no matter what port I tell ssl to listen on.
Any ideas?

it cetainly looks that way .. now this is a long shot,, but check your /etc/services and see if the 8443 port is defined?
pcsync-https 8443/tcp # PCsync HTTPS
pcsync-https 8443/udp # PCsync HTTPS
pcsync-http 8444/tcp # PCsync HTTP
pcsync-http 8444/udp # PCsync HTTP

I was told by this:
If you are using the latest Skype, go to Tools -> Options -> Advanced -> connection. Disable the 'Use port 80 and 443 for alternatve.. '
Sign Out and Close all Skype windows.
Thanks for the advice. It Worked!!!
