John Kounis, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
** Description changed:
Binary package hint: ntp

- I believe this is a duplicate of bug
https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/569919, which has a status
of Fix Released
- But I have the fix, and the problem still occurs.
Every 5 minutes, ntpd complains about being unable
I can confirm that this bug is still present in 12.04 (new install, not
an upgrade).
The workaround is to add the following to the end of /etc/ntp.conf and restart
ntp:
# Prevent it flooding syslog with error messages:
interface ignore ipv6

ntp complains about ipv6 errors every 5 minutes
To manage
The problem does not resolve for me. I still get the following errors
(uptime is 3 days):
Apr 27 22:01:44 pgfs ntpd[2535]: bind() fd 24, family AF_INET6, port 123, scope
4, addr fe80::217:31ff:fef8:f63f, mcast=0 flags=0x11 fails: Cannot assign

Hi John
I've been reviewing all IPv6 related bugs associated with NTP; although
I could reproduce this in January I am now unable to get the same
results.
Are you still seeing this issue? I'm aware that there is an upstream
bug related to the interface being in a tentative state but that should
I am currently having this issue, but it might not be an ntp bug, but
rather a kernel bug.
If you assign an IPv6 address to a virtual device composed of real sub-devices
(e.g. to a bonding or bridge interface), the address will be wrongly detected
as duplicate (marked as tentative dadfailed).
(Setting importance to low since it has an easy workaround)

Marking Confirmed based on the linked bug reports.
However, the linked reports contradict each other.
http://bugs.ntp.org/show_bug.cgi?id=1134 suggests a simple workaround in
userspace. The redhat bug (and poster above) suggests there is a kernel
bug. So I've marked this as also affecting
Confirmed using the following setup:
qemu/libvirt vm running Maverick 10.10 i386 install; added two
additional network adapters and then bonded eth1 and eth2 using a fairly
standard bonding configuration (ifenslave as described above). ipv4
addressing works fine - however get the same error
Also noticed that even without bonding I get the same message every 5
minutes from ntp (but on the eth0 interface).
This could be related to bug 697592.

Are there any apparmor denied messages in kern.log for ntpd?

Correction - this only happens when the address is in 'tentative' state;
this resolves shortly after boot (see
https://bugs.ntp.org/show_bug.cgi?id=1134)
