[Galene] doc auto-hébergement serveur Galène (in french)

[Galene] doc auto-hébergement serveur Galène (in french)

[Nicolas Mesnier]

Dear all,

I have just written (in french) a small step by step tutorial to set-up
a home Galène server (behind a NAT) in a VM with a reverse proxy.

    http://nmesnier.free.fr/galene.html

It is dedicated to newbies like me wishing to self-host their Galène
server among other services. It is also a way to share the precious
help Juliusz Chroboczek gave me.

If it can help...
Nicolas

Hi,

Great job !

As far as I can see it will work only with IPV6 .... I suspect you have a freebox :-)

To check : 
Deactivate the ipv6 on your VM and connect from outside (for example with a 4g connexion) or simply type /relay-test in the chat.

May be the script I did write might help : https://gitlab.Inria.fr/rouillie/visio

All the best

Hi,

Thanks for your interest.

I'm behind a Livebox 5 and the set up is intented to be IPv4.
It works with cell phones over 4G connexions.

It seems it is just ufw's config that enable IPv6 by default. I've disable
it setting "IPV6=yes" to "IPV6=no" in "/etc/default/ufw", reloaded ufw,
restarted nginx and having a conf call with a friend over Galène and
everythings works execpt the "/relay-test" which is still "timeout"...

Bests,
Nicolas

If /relay-test is timeout then the turn is not used and you are still in ipv6 if it works.

Connect with firefox from outside with your 4G connexion , 
switch on your webcam, open a tab and type about:webrtc <about:webrtc>  as url, you will then get the information about ICE.

If you want to disable IPV6, then connect into you VM and type :

sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1

Then check your network interface as no IPV6 access by typing :

Ifconfig

Once you have disabled IPV6 to the test with firefox again and try to switch on a webcam using again firefox ….

Bests,

Fabrice.

Many thanks for helping.
Indeed, you're right: my set up only works with IPv6!

1. I've seen in firefox, as you expected, an IPv6 connexion for ICE...
2. I've then try to disable IPv6 on my VM

        # sysctl -w net.ipv6.conf.all.disable_ipv6=1
        # sysctl -w net.ipv6.conf.default.disable_ipv6=1

   then reload Galène and observed the connexion was now IPv4
   but I can't share audio nor video
   and the /relay-test is still timeout...

Discussions about your installation script suggest to install a coTURN
server. I've tried the method you described but without any success...

As a newbie, I don't figure what's the problem of such IPv6 configuration,
since it seems accessible via "standard" IPv4. Is that a lack of
compatibility with all devices/connexions?

No doubts real tests with my students back from holidays on the 26th
will reveal me (part of) the problem...
It would be a pleasure if someone can help me to avoid such a situation!

This confirms that the turn is unreachable.

You did apply exactly the documentation ? (Strange since we have exactly the same installation …)
Be careful : you need to open much more ports as you did before ...

With IPV6 there is no NAT so that the turn is useless.

Your turn is simply not working.

Not necessarily since it suffice that they all have IPV6 connexions.

A good test might be for a 4G connexion using SFR which has almost no IPV6 or also Free mobile who activated IPV6 only recently.

Please, try this with a fresh VM following line by line the instructions :

Hi,
I followed your script
https://gitlab.inria.fr/rouillie/visio/-/tree/master/galene
to install and configure a coTURN server on port 1194/tcp.

A key point to get my config working as full IPv4 was to disable IPv6
connectivity on the Livebox 5.

Now the tchat /relay-test is successful.
Isn't it a good indicator of IPv4 connexion, as well as ICE informations
got with about:webrtc in firefox?

Anyway, I've updated my tutorial http://nmesnier.free.fr/galene.html.

Thanks a lot for your help!
Nicolas
