[Pkg-utopia-maintainers] Bug#533233: avahi-autoipd should not overwrite route when other interfaces are configured

[Carnë Draug]

Hi

I'm facing the same problem on my new machine. The default
configuration makes it lose the internet connection soon after
startup.

Here's exactly what happens. The system has two interfaces, eth0 and
wlan0. Without an ethernet cable connected (standard since this is a
laptop), the wlan0 interfaces gets an IP address quickly from dhcp and
becomes the default route. Slightly after this (around 1 minute),
avahi seems to timeout after being unable to get an IP address for
eth0 (there's no cable after all) and gets an APIPA address for eth0
(and eth0:avahi) which then becomes the default route. But why is an
interface that is down even being added to the route? And why is it
"stealing" the default route from the properly configured interfaces?

Bringing eth0 down fixes it only temporarily. A few minutes after
running 'ifconfig eth0 down', that interface comes up again
automatically and becoming the default route (wrong). I have "fixed"
tis temporarily by commenting all the eth0 lines in
/etc/network/interfaces

Also, it appears that there's other people facing the same issue
(besides me and the two other that reported this first). This thread
[1] on the debian forums is likely to be the same bug.
