On this page you will find how to install and configure a Kurento Media Server environment.
Requirements
Hardware
Minimum hardware requirements are:
2 cores - CPU
4GB di RAM
40GB di HDD
Software
Recommended operating system is Ubuntu Linux 18.04 LTS Server.
Network
On your firewall you will have to enable these ports in order to have your Kurento Media Server working:
Inbound
8888/TCP
50000-65000/UDP (RTP stream)
For security reasons, port 8888/TCP has to be opened specifying IP 35.180.105.193 as source address, that corresponds to our API server IP address.
Regarding RTP stream ports, you have to open these ports to any (0.0.0.0/0) or, if users connects from a VPN or specific IP, just open that IP address source.
Outbound
50000-65000/UDP (RTP stream)
Outbound stream needs to comprehend in its destination networks the same networks specified as source on inbound rule; this rule can be opened to “any” without causing any security issue.
Install kurento media server
Once you install the operating system, run the following commands in order to install Kurento:
| Code Block |

sudo apt-get update && sudo apt-get install --no-install-recommends --yes gnupg
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 5AFA7A83
source /etc/upstream-release/lsb-release 2>/dev/null || source /etc/lsb-release
sudo tee "/etc/apt/sources.list.d/kurento.list" >/dev/null <<EOF

sudo apt-get update && sudo apt-get install --no-install-recommends --yes kurento-media-server

Configure kurento media server
Here you find the file paths and the changes to apply.
In order to configure RTP stream ports you have to modify the file:
/etc/kurento/modules/kurento/BaseRtpEndpoint.conf.ini
Modify minPort and maxPort rows entering selected RTP range, for example:
minPort=50000
maxPort=65000
| Info |
|---|
These ports are the same ports that you have to open in your firewall inbound rules |
In order to configure STUN and external address, modify file:
/etc/kurento/modules/kurento/WebRtcEndopoint.conf.ini
Modify stunServerAddress and stunServerAddress values indicating selected parameters, for example:
stunServerAddress=stun.l.google.com
stunServerPort=1932
| Info |
|---|
It's possible to use a public STUN as reported in the example or, if present, you can specify an internal STUN server; always keep in mind that Kurento’s IP must be enabled to reach your STUN server. |
externalAddress=15.237.148.189
| Info |
|---|
Insert your public IP address; this IP must be communicated to our staff in order to enable inbound stream on our firewalls. |
