[Pkg-utopia-maintainers] Bug#547974: avahi-daemon: Can't resolve names via ipv4

[Sam Morris]

Package: avahi-daemon
Version: 0.6.23-3lenny1
Severity: normal

For some reason that's beyond me, I can't get avahi on this particular system
to work with ipv4.

The system can resolve its own name fine, but anything else just
doesn't show up.

$ avahi-resolve-host-name durandal.local
durandal.local	fe80::21c:bfff:fe9c:776c

$ avahi-resolve-host-name -4 durandal.local
Failed to resolve host name 'durandal.local': Timeout reached

Unfortunately I don't see anything suspicious in the system logs.

Other systems are similarly unable to resolve the system's host name
via ipv4, but ipv6 works fine.
