As said in the title, I bought a "Duet", and while I am getting more and
more intimate with it, I don't know who goes wrong here, the Controller
or the Receiver.
The problem is simple: the Duet in bridged mode does not wake my SC
server. It never did.
Isn't the *Receiver* supposed to send the WOL packets over the network
? I see bugs filed (and resolved...) about the Controller being able to
send WOL packets but nothing much about the Receiver.
Anyone in bridged mode with a server that wakes-up ? Is this issue in
the radar already ?
This is a test trace:
Code:
--------------------
1) Setup a listening host on my lan sudo tcpdump -vvv -x -i 1 -n -t -l -s
256 "(multicast or broadcast) and udp"
tcpdump: WARNING: eth0: no IPv4 address assigned
tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 256
bytes
2) Sleep SC 7.2 server, music playing.
3) On some host: wol -vvv 00:17:31:38:46:c8
Waking up 00:17:31:38:46:c8 with 255.255.255.255:40000...
Reads this on listening host:

Server wakes-up
4) Sleep SC server
5) Squeezecenter classic, playing until buffer is empty, looses server and
goes black screen, remote control a bit numb, then able to do right arrow to
reconnect. Says "Waking-up SqueezeCenter":

Server wakes-up
6) Duet bridged mode, playing, immediate blue fan on the Controller,
Controller keeps responding to inputs (not being able to pass them on to the
server), then displays a "Wait" message.
Reads this:

This is the Controller (.251) trying to wake the Receiver (.250)...
The Recever never sends a WOL packet to the server, hence the server does not
wake-up. It sends frames however, but they don't exactly look like WOL packets
and I can't see my servers MAC in it:
The most often seen are like this:
IP (tos 0x0, ttl 64, id 1267, offset 0, flags [none], proto: UDP (17),
length: 46) 192.168.1.250.3483 > 255.255.255.255.3483: [udp sum ok] UDP, length
18
0x0000: 4500 002e 04f3 0000 4011 b32a c0a8 01fa
0x0010: ffff ffff 0d9b 0d9b 001a 7116 6400 072f
0x0020: 0000 0000 0000 0000 0004 2016 2582
And from time to time this longer one:
IP (tos 0x0, ttl 64, id 1238, offset 0, flags [none], proto: UDP (17),
length: 107) 192.168.1.250.17784 > 255.255.255.255.32772: [udp sum ok] UDP,
length 79
0x0000: 4500 006b 04d6 0000 4011 b30a c0a8 01fa
0x0010: ffff ffff 4578 8004 0057 c2b4 0002 0000
0x0020: 0000 0000 0001 0004 2016 2582 0001 c001
0x0030: 0000 0100 0100 090c 0f77 6169 745f 736c
0x0040: 696d 7365 7276 6572 0b02 3037 0a04 3030
0x0050: 3035 0902 3437 030a 7371 7565 657a 6562
0x0060: 6f78 0207 416e 7469 6265 73
Reconnect fails. Controller "forgets" the SC server, game over.
And then the Controller said "battery empty". Sure, I can fix that.
