Roon Bridge x86 Linux Debian not showing up?

Roon Software Discussion Linux
1

All,
Was fooling around and installed the x86 version of Roon Bridge on a small computer. The install went well I plugged a DragonFly into the USB port and alsa set that up just fine. If I run the start.sh again I get the error about exclusive access so I figure it’s running. I see the mono-sgen running when I run top in ssh terminal.

But I don’t see the Bridge on either macOS setups I have running. One of them is on the same Ethernet Switch the other is on another line. But I can access the system through ssh from either computer meaning that the Bridge should show up as well on either.

I can see that the DragonFly is setup under alsa and there is also a HD Audio port on the mother board.

Any ideas? I might try this with Ubuntu and see if that makes a difference, though Debian seems to be a little better on this system.

Thanks,
Gordon

Does a netstat -g show it joining 239.255.90.90?

Using top I only see this mono-sgen which does appear in the working folders under RoonBridge, but I really don’t see anything else.

Anyone got any ideas?

Ok thought I would ping the damn thing and sure enough it works fine, pretty quick through my router and bridge.

Just a quick update… I upgraded Debian from 8 to 9 stretch and installed the Roon Bridge, same problem.

@debian:~$ netstat -g

eth0 1 ip6-allnodes
eth0 1 ff01::1st_place_medal:

So I can see the mono is running and the virtual ip address being generated and I can ping that address just fine at any byte length but nothing under my macOS roon for network except air play from my Airport express. I am ssh into the Debian right now and I can ping it from any machine on that switch or here in my office.

I have 845MB of ram available of the 1GB installed.

Any ideas?

Silly question, but you haven’t accidentally set it to a private zone? I ask because I did that myself once.

Also I have a dragonfly red running off a debian headless system and have no issues.

Chris,
Private Zone? I don’t see that in the desktop setup anywhere. The bridge code would have to be customized to create a private zone I would think. I do see my airport express on the net on the same ethernet switch that my x86 is on.

Thanks,
Gordon
