Getting Roon core on Linux to look at all interfaces for network streamers

[JimU]

Core Machine (Operating system/System info/Roon build number)

Debian Linux, latest Roon.

Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet)

Wifi + Ethernet

Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)

Ethernet connected

Description Of Issue

On my Linux with Roon core, I usually use USB to connect to a dac.
Internet conneciton is via wifi.

But, I’ve just added another Roon-Ready streamer onto ETH0 attached to this Linux device, which I configured manually, along with a DHCP server running on this Linux box, so the attached devices get addresses.

The main network is via WiFi from this Linux box.
How do I get Roon Core to also look on ETH0 for my other devices?
Are there config files that drive which network interfaces Roon looks on?

Thanks, Jim

It already looks at all interfaces… At least it does on my CentOS 7 based Core.

If its not discovering things, make sure host-based firewall/etc isn’t interfering.

Thanks, I’ll look into the firewall question.

I verified iptables (firewall) is not active. Still no-go.

Managed switch with IGMP snooping enabled and no IGMP querier on the network? The core discovers RAAT endpoints via multicast.

Thanks!

So it was just a setting missing on my streamer, lol!

Hi @JimU,

Welcome to the forum! It sounds like you’re situated after @cwichura’s advise, but do confirm. I’ve also moved your thread over to the #tinkering section since it’s a bit more advanced than the typical Roon setup.

All set now, thanks!
