Both machines have (192.168.1.x) IP addresses - handed out by dhcp
running on the router, both have
255.255.255.0 netmasks. iTunes on the
XP machine can see the share music from rhythmbox on the Linux box so I
think the network is ok. I don't have a firewall installed
on the Linux box (to the best of my knowledge) but how would I go
about verifying that there isn't some bit of code somwhere doing some
blocking? From the lack of activity in the avahi-daemon log it would
suggest that these UDP broadcast packets are being filtered somewhere
in the Linux boxe's network stack.
Thanks for all the help so far, hope I'm not boring people,
Barney
