I have installed Slimrio, and it will not connect to my Slimserver.

Wireshark tells me it is trying to connect to udp port 18678, rather than the slimp3 broadcast for a server address I would expect.

Slimrio appears to have booted correctly - the console screen says "No connection to slimserver".

Any ideas? Am I missing something obvious?

Cheers

Tim

I'm making no progress on this, in spite of having spent several hours investigating :-(

Slight correction to the symptoms - once booted, the device sends no packets - it is the Audio Manager software that is trying to connect on udp 18678.

Telnetting to port 5000 gets rather random results - sometimes the chars echo, sometimes not, and I can't get the simplest of commands (e.g. ls or pwd) to run. This leads me to believe that slimrio simply isn't working properly, unless I am doing something wrong? Has anyone used the port 5000 interface? Do you need to do anything special to make it work?

Cheers

Tim

PS I have tested it using the original Rio software - works perfectly

If it's getting to the "No connection" screen, you've already done all the hard work since we know the networking is up and able to run NFS. At that point, slimrio will be repeatedly sending out UDP broadcasts to port 3483; I can't imagine why you wouldn't see them unless perhaps there's some funny switch or firewall in the way.

Were you connecting to port 5000 from the same machine that served it the NFS image? If not, give that a try. Can you ping it from there?

What are you using to give it a DHCP address? Could it have been given the same address as another host on the network?

I've used telnet---but nc (netcat) is safer because it doesn't try to do any fancy quoting or negotiation like telnet can.

Thanks very much for the response Robin.

I am making some progress, but it still doesn't work :-(

I have tried simplfying the network (Windows Server 2003 (dhcp, audio receiver manager, wireshark), ddar, hub) - no improvement.

Tried using nc instead of telnet, and I can now get a sensible console session.

Killing slimrio and restarting with -v gets the message:

=> sending discovery request
sendto: Network is unreachable

Repeating with the -s flag and the ip of the slimserver gets:

=> sending discovery request
<= discovery response from <ip address>
No connection to slimserver

Wireshark shows the discovery requests & responses.

I'm baffled; so much works, yet it doesn't work!

Can you suggest any diagnostics I could do now I have a console session?

In particular how can I check the network configuration - I see busybox doesn't have ifconfig?

Thanks in advance.

Cheers

Tim

I have now got a full boot log (posted below) - again pretty baffling, it all looks clean, no error messages to speak of. The only thing I don't like is the gw=ffffffff line(s).

Is anyone in a position to compare it with a working log?

Cheers

Tim

Not me. But you're right that gw=ffffffff looks wrong. Check your DHCP server configuration on host 192.168.0.14 -- is it handing out a bogus gateway address?

Peter

Just what I've been checking. It has option 003 (Router), and it is set to exactly what you would expect - 192.168.0.1

:-(

I've solved this.

Turns out to be a combination of "features" of the DHCP code in the server and the client. The client includes a Vendor Class (empeg:mercury) in the DHCP request. The server (Windows Server 2003) returns a DHCP lease _without_ including option 3, (router / default gateway - I assume it does this because of the presence of a Vendor Class - it shouldn't do according to the specs, but it does). The client, not receiving the expected option 3, uses the really useful default of 0xffffffff. When Slimrio loads, this default causes the IP stack to crash.

Now all I need to do is knock up a utility to provide the correct DHCP response, and coexist with my current DHCP setup and I'll be laughing.

Cheers

Tim
