---- Commands to set up a TURN Server -------

I have used:
1.Ubunto server 20.04 LTS.
2.Dedicated Public IP address or FQDN.

Step 1: install coturn.
# apt-get install coturn

Next enable coturn as service(use the editor of your choice):
# nano /etc/default/coturn

Uncomment the last line,save and close the file:
TURNSERVER_ENABLED=1

Let's config the coturn file,open the turnserver.conf with an editor.
# nano /etc/turnserver.conf

Change the Value of the following lines::
listening-port=3478
tls-listening-port=5349
listening-ip=YourTurnServerIPAddress
relay-ip=YourTurnServerIPAddress
realm=FQDNoftheTurnServer
total-quota=100

Uncomment the following lines:
fingerprint
lt-cred-mech
stale-nonce
no-multicast-peers
use-auth-secret
static-auth-secret=north

Save and close.

Let's paste this command to generate a secret string:
# openssl rand -hex 32

Copy the generated secret string and paste it into the turnserver.conf

Note :
Enabling “use-auth-secret” and setting a “static-auth-secret” will prevent
unauthorized usage of your TURN server and is highly recommended!

Now restart the coturn service.
# service coturn restart

- End -
