Linux mDNSResponder on two interfaces

Hello Rendezvous list:

We are still having difficulties running Apple's Posix mDNSResponder
on a small embedded Linux box with two interfaces. We are now using
the latest version from CVS and still it does not work on the second
interface. The box has both wired (eth0) and wireless (eth1) interfaces.
It is advertising an http service and an ssh service. It works great on the
wired interface eth0. I can watch the Rendezvous bookmark appear in
Safari. But the same does not happen on the wireless interface eth1.
Currently, eth0 is connected into a managed network with DHCP server,
and eth1 initializes to a link-local address. The network itself seems OK
as I can surf to it wirelessly using an IP number. Both interfaces are
being registered, see log below. The log reports some ignored packets
from both interfaces but I'm not sure this is significant. I've dug into
the code but have not found a "smoking gun". Interestingly enough,
occasionally, the Rendezvous bookmark will appear, usually with some
delay, but I can never surf to it. I get no response from the browser.
Could the problem be a routing issue internal to the Linux box?
Any help is greatly appreciated.
Richard
