Websocket server only listening on tcp6

[kewalaka]

Hi

I’m trying to use 4head on Android as a remote to OSMC (RaspPI 3), and it is unable to connect to the websocket server, I’m running the latest build offered via OSMC update.

Despite trying various things (see below), it is still only listening on tcp6:

osmc@pi:~$ sudo netstat -ntlp | grep kodi

tcp6       0      0 :::36667                :::*                    LISTEN      323/kodi.bin

My latest attempt was to use connmanctl to turn off ipv6, as suggested here:

[Solved] IPv6 not disabling on eth0 during Pi2 boot

I have used the following commands in sysctl.conf to disable IPv6: net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 net.ipv6.conf.eth0.disable_ipv6 = 1 Running sysctl -p correctly activates these changes on both local and eth0. However, if I reboot the system, eth0 is assigned an inet6 address according to ifconfig. eth0 also gets an inet6 address if I disconnect and then re-connect the network cable after running sysctl …

(noting the dev says this is off by default now).

I’ve also tried editing /etc/sysctl.conf, just in case, with these settings:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

I’ve rebooted the PI a few times now…

Is it necessary to enable ipv6 to get the websocket server to work, or is there another way?
