Description Andres Rodriguez 2009-04-27 17:35:36 UTC
Description of problem:

From avahi bug tracker: In the case where you have a system connected to a hub which returns packets to the sender, autoipd always lists every IP address as taken, even when it isn't. The attached patch fixes this problem by ignoring conflicts when the packet is generated by the local address. I cannot think of any downsides to this approach. 

Please see for the patch: http://avahi.org/ticket/265


How reproducible:


Steps to Reproduce:
1. Create qemu with multicast networking
2. Try to assign IP with avahi-autoipd on the machines using the qemu mcast networking
3. Address will never be assigned since it *thinks* someone already has the IP address that autoipd is trying to assign.

Comment 1 Bug Zapper 2009-06-09 14:39:44 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

Comment 2 Karel Volný 2010-01-11 16:15:22 UTC
resetting the version to 'rawhide' as the upstream tracker says it is going to be fixed in Avahi 0.6.26 and we still have just 0.6.25 available
