[avahi] Getting avahi up and running

[Barney]

I have been trying to get avahi up and running on a laptop running
Debian/Linux but am not able to get it to see other devices on the network.
My aim is for rhythmbox to be able to see my iTunes shared music on an XP
machine (both are connected via a router). I have had success with the XP
machine seeing shared music on the Linux latop but not the other way round
(see thread at http://mail.gnome.org/archives/rhythmbox-devel/2005-November/msg00056.html
for background). When I run avahi-discover on the linux box I get the
following:

Browsing domain 'local' on any.0 ...
Browsing for services of type '_daap._tcp' (iTunes Audio Access) in domain
'local' on wlan0.2 ...
Browsing for services of type '_workstation._tcp' (Workstation) in domain
'local' on wlan0.2 ...
Found service 'laptop' of type '_daap._tcp' (iTunes Audio Access) in domain
'local' on wlan0.2.
Found service 'bunkerbay [00:12:17:bd:78:00]' of type '_workstation._tcp'
(Workstation) in domain 'local' on wlan0.2.
Service data for service 'laptop' of type '_daap._tcp' (iTunes Audio Access)
in domain 'local' on wlan0.2:
Host bunkerbay.local (192.168.1.67 <http://192.168.1.67>), port 3689, TXT
data: ['org.freedesktop.Avahi.cookie=3578020801']
Service data for service 'bunkerbay [00:12:17:bd:78:00]' of type
'_workstation._tcp' (Workstation) in domain 'local' on wlan0.2:
Host bunkerbay.local (192.168.1.67 <http://192.168.1.67>), port 9, TXT data:
['org.freedesktop.Avahi.cookie=3578020801']

where 192.168.1.67 <http://192.168.1.67> is the ip address of the linux
boxso there is no mention of the XP machine. This is while the XP machine is
on and running iTunes with sharing enabled. The XP machine can see and play
music from the laptop. Running tcpdump on the laptop produces output like:

bunkerbay:/home/bdalton# tcpdump ip multicast

all the packets seem to originate from the laptop
(192.168.1.67<http://192.168.1.67>)
and there is no log of packets coming from the XP machine
(192.1.67.64<http://192.1.67.64>
).

My ifconfig looks like:
bunkerbay:/home/bdalton# ifconfig -a

Anyone have any idea about what might be wrong or how I can diagnose
further?
Thanks
Barney
