[Pkg-utopia-maintainers] Bug#653920: avahi-daemon: Avahi can't communicate between hosts with iwl3945 and skge interfaces unless one interface is in promiscuous mode

[Sam Morris]

Package: avahi-daemon
Version: 0.6.30-5
Severity: normal

I have a Samsung Q45 laptop with the following wireless interface:

02:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
	Subsystem: Intel Corporation PRO/Wireless 3945BG Network Connection
	Kernel driver in use: iwl3945

and a desktop with the following ethernet interface:

00:0a.0 Ethernet controller: Marvell Technology Group Ltd. 88E8001 Gigabit Ethernet Controller (rev 13)
	Subsystem: ASUSTeK Computer Inc. Marvell 88E8001 Gigabit Ethernet Controller (Asus)
	Kernel driver in use: skge

Both are amd64 systems running Linux 3.1.

Neither system can resolve the name of the other (tested with
avahi-resolve-host-name -4).

If I run tshark on the laptop, I can see the MDNS queries being
received, and the responses being transmitted; the desktop just ignores
the responses.

If I run tshark on the desktop, both machines start being able to
find each other, so it appears that putting the skge-using interface
into promiscuous mode prevents further diagnosis of the problem on the
desktop end.
