Can't connect to RoonServer on Linux

Support
1

Hi,

I just installed RoonServer on a Fedora 22 machine. Check.sh reports all OK and the install script reports success. Systemctl shows the service running, but no joy seeing it from the client on my Mac.

I have an instance of RoonServer on a Kubuntu virtual machine running on the same Fedora 22 box. That one works fine. Curious.

Any ideas?

Thanks - Carl

I can’t see an error in the status.
So I’d start to check the networking basics.
Fedora 22 is not running in a vm, right?
Can you check the IP address of all relevant devices? Any firewall involved?

Thanks for the quick response!

No, the Fedora instance is on the hardware.

And yes, there is a firewall involved. I just stopped it and lo and behold: a connection.

Now the question becomes configuring the firewall to allow the connection. I vaguely remember seeing something that said that Roon uses a gizmillion noncontiguous ports. I’ll have to wait a while before I try to configure it because right now the collection is importing (it’s on another server) and I’ll need to turn the firewall back on to use the configuration tool or test if I use the conf files. Any idea how I should proceed when I am able?

Yes, definitely the firewall.

Now, does anybody know the ports, so I can attempt to write a firewall rule?

It’s not a deal breaker if I can’t get the firewall sorted. That machine is already behind a firewall at the router and threats from inside my own network are minimal. But still …

I can remember that it was recommended somewhere to use an application layer firewall and to exclude RoonServer from it. But I can’t find the post where I have read about it…

Indeed.

Yeah. I have such a firewall on a Windows machine. You tell it the path of a program and anything that program calls for is okeedokey. That and 50 cents…, as they say.

firewalld, on the other hand, seems to be more of a “you tell me exactly what ports you want and that’s that” sort of affair. Bad news for a basically ignorant manpage and trial and error kind of guy like me. Especially since I don’t know the port ranges and I vaguely remember seeing a post here that said Roon wasn’t as simple as just specifying a port range anyway.

Hmmm. [shuffles off to see if there are any third party fancy firewalls for Linux…]

And…

A bit of Google searching reminded me that SELinux is the application layer firewall for Fedora. It’s there. It’s a PITA. And it’s not causing this particular problem.* It’s its counterpart that’s bedeviling me.

*I suspended SELinux right off the bat when Roon couldn’t communicate. Did no good. When I stopped firewalld, the problem vanished. Thus, I’m convinced that firewalld is the bad actor.
