i am new around here and I just installed kurent media server over a VPS in digitalocean.com
I have assigned a subdomain on dns server.
The served has a public IP and own domain with ubuntu 14.04 64bit.
1st question:
I had any problem installin kurent media server 6 and following the documentation, I undestand that i my case I don't need to install a turn and stun server ...it's correct?
2nd question: I tried the tutorial 3 and 4 but neither works for me ... before investigating further, let me know if you need to have installed a turn stun server.
Thank you
MaX

Hi Max,
Welcome to the list! Hope you have a good experience with Kurento :-)
About your question, if your server does not have a public IP, but a public and a private IP, and there is some NAT going on (most likely) you'll definitely need at least STUN. Here is a good post about WebRTC, STUN, TURN and signaling. Worth a read if you are starting! Getting those things right in the beginning will save you a lot of trouble later ;-)
One way to see in the logs if you need STUN, is if you KMS is generating candidates with the public IP from your server. You can just grep the log file for your IP, and see if something comes out.
Another thing that can be happening, is that you need to open certain ports. There are some posts in the list about that (this one, for instance), and will show you which ports you need to open.
Please let us know if you need STUN with your setup, as we've never worked with digitalocean :-)
Cheers,
Ivan Gracia

If I'm not wrong, DigitalOcean is based on OpenStack and the public IP is just a floating IP. If this is the case, a STUN server will be needed for certain.

Hi Ivan,
no, digitalocean vps have a real public IP. Here the ping to one o
server of mine where I'm testing Rocket.chat:
ping chat.XXX.XXX
PING chat.XXX.XXX (178.62.XXX.XXX) 56(84) bytes of data.
64 bytes from chat.XXX.XXX (178.62.XXX.XXX): icmp_seq=1 ttl=47 time=72.5 ms
64 bytes from chat.XXX.XXX (178.62.XXX.XXX): icmp_seq=2 ttl=47 time=89.0 ms
64 bytes from chat.XXX.XXX (178.62.XXX.XXX): icmp_seq=3 ttl=47 time=92.8 ms
as you can see, the IP is public, and I can have servers in europe,
usa, singapore.....
These VPS servers have only one IP (one distinct for server) and you
can connet with ssh and install the software as you need.
So... still I need STUN, TURN and signaling server?
I suspect that my testing doesn't works because I tried to install
kurento media server in the same vps where I'm testing Rocket.chat,
and the ports can be the sames.
regards

Where are you running that command from? I think it's not giving the information you think it's giving. As Luis says, if degitalocean is based on OpenStack they'll assign you a floating IP, and have an internal network with your server's IP. Then they'll route all the traffic from the floating IP to the server's internal network IP. I think you are going to need that STUN server.
Just to be sure, ssh to the machine, and do ifconfig. See what you get there. It's probably a 10.X.X.X IP, or other private address space IP.

Ok, so looks like you won't need STUN :-) In any case, you still need to open all UDP ports, as you are not going through STUN. After doing that, turn off your Rockket.chat app, just in case, and setup the hello-world tutorial. Once you have that, try to connect to the tutorial in http://178.62.239.231:8081/ Search in the KMS logs for your public IP, an see if you generate candidates with that IP.
Attach (don't paste, as they are quite big) your KMS log, along with your client logs.
