Describe your issue

Hello there,

For a little while, my Mumble Server on my Yunohost stopped listening on IPv4.
It was only reachable in IPv6.

If you are in this particular case as well, here is a quick and dirty fix:

1. make sure that this is the right problem:

root@yunohost:~# sudo ss --listening --processes --udp --numeric | grep murmurd
UNCONN 0      0               [::]:64738         [::]:*    users:(("murmurd",pid=51966,fd=42))

If you have a line with 0.0.0.0:64738 0.0.0.0:*, then your mumbleserver is listening on its port with IPv4.
My post is no help to you ; otherwise:

2. identify the configuration file for mumbleserver:

root@yunohost:~# grep "ExecStart" /etc/systemd/system/mumbleserver.service
ExecStart=/usr/sbin/murmurd -ini /var/www/mumbleserver/mumble-server.ini

Here, mine is /var/www/mumbleserver/mumble-server.ini.

3. edit this file and modify the host parameter so that it is set to "0.0.0.0 ::".
   Let’s verify:

root@yunohost:~# grep "^host" /var/www/mumbleserver/mumble-server.ini
host="0.0.0.0  ::"

4. reload or restart the mumbleserver service

root@yunohost:~# sudo systemctl restart mumbleserver.service

5. verify that mumbleserver is listening on both IPv4 and IPv6:

root@yunohost:~# sudo ss --listening --processes --udp --numeric | grep murmurd
UNCONN 0      0            0.0.0.0:64738      0.0.0.0:*    users:(("murmurd",pid=51966,fd=42))
UNCONN 0      0               [::]:64738         [::]:*    users:(("murmurd",pid=51966,fd=43))

Hope this helps,
