Hello Lennart, Thanks for your response. I have the dump from wireshark, I'm attaching it. This error was while implementing qemu mcast networking and using avahi-autoipd to obtain network address. The implementation of qemu networking is the following: -net nic,vlan=1,macaddr=52:54:00:12:34:01,model=virtio -net socket,vlan=1,mcast=<a href="http://230.0.0.1:1234/" target="_blank">230.0.0.1:1234</a> Thanks for your help. <div class="gmail_quote">On Tue, Apr 21, 2009 at 12:43 PM, Lennart Poettering <<a href="mailto:lennart@poettering.net" target="_blank">lennart@poettering.net</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div>On Tue, 21.04.09 11:46, Andres E.

Try wireshark to find out if there actually are conflicting ARP packets sent out. <div> > > [root@localhost ~]# avahi-autoipd eth1 > Found user 'avahi-autoipd' (UID 499) and group 'avahi-autoipd' (GID 499). > Successfully called chroot(). > Successfully dropped root privileges. > Starting with address 169.254.2.176 > Callout BIND, address 169.254.2.176 on interface eth1 > Received conflicting normal ARP packet. > Callout CONFLICT, address 169.254.2.176 on interface eth1 > Trying address 169.254.189.32 > Callout BIND, address 169.254.189.32 on interface eth1 > Received conflicting normal ARP packet. > Callout CONFLICT, address 169.254.189.32 on interface eth1 > Trying address 169.254.39.206 > Callout BIND, address 169.254.39.206 on interface eth1 > Received conflicting normal ARP packet. > Callout CONFLICT, address 169.254.39.206 on interface eth1 > Trying address 169.254.66.131 > Callout BIND, address 169.254.66.131 on interface eth1 > Received conflicting normal ARP packet. > Callout CONFLICT, address 169.254.66.131 on interface eth1 > Trying address 169.254.223.251 > > And so on. > > Thanks for yor help > </div>> _______________________________________________ > avahi mailing list > <a href="mailto:avahi@lists.freedesktop.org" target="_blank">avahi@lists.freedesktop.org</a> > <a href="http://lists.freedesktop.org/mailman/listinfo/avahi" target="_blank">http://lists.freedesktop.org/mailman/listinfo/avahi</a> Lennart -- Lennart Poettering Red Hat, Inc. lennart [at] poettering [dot] net ICQ# 11060553 <a href="http://0pointer.net/lennart/" target="_blank">http://0pointer.net/lennart/</a> GnuPG 0x1A015CC4 _______________________________________________ avahi mailing list <a href="mailto:avahi@lists.freedesktop.org" target="_blank">avahi@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/avahi" target="_blank">http://lists.freedesktop.org/mailman/listinfo/avahi</a> </blockquote></div> -- Andres E.
