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
