IGMPproxy failed MRT_INIT failed; Errno(92): Protocol not available

[bclevering]

I've got a problem to get IPTV (KPN) to work.

The big problem is that i got a new device (UDW (Unifi Dream Wall)) in early access... (looks very nice)

i found out that the ip address (WAN ethernet port is eth18 or should i use ppp0?) but it's still not working:

Please share the following output with the developers:
=== Configuration ===
WAN Interface: eth18
WAN VLAN: 4 (dev iptv)
WAN DHCP: true (options "-O staticroutes -V IPTV_RG")

Based on the following log:

MRT_INIT failed; Errno(92): Protocol not available

It looks like the Linux kernel on the UniFi Dream Wall does not have multicast routing enabled. You'll have to ask Ubiquiti to enable this feature for newer firmware releases or try to port udm-kernel-tools to that platform.

[fabianishere]

It uses a cross-compiler, so you should build it from your development machine.

sounds like a lot of work? I could try this, but i think i need some help setting things up and letting it work for the Dream Wall...

Can someone help?

[bclevering]

@fabianishere i tried compiling the kernel but it keeps saying that ssh-proxy cannot be found...

Looks like it's an issue because "unifi-os shell" also isn't working because i go straight into the shell...

[fabianishere]

The firmware is probably similar to the UDM SE where there is not a container anymore and the controller runs directly on the root filesystem.

[bclevering]

@fabianishere looks like it indeed;

Should I try this solution I found on tweakers.net? https://github.com/mories76/udmprose-iptv

[fabianishere]

Thats based on an old version of this project and also requires kernel support for multicast routing, so it won’t work probably.
