Hi!

[First of all, I have posted this question already on the FreeBSD
forum -- so far without replies -- and now my hope is that the set of
subscribers here and those of the forum do not completely coincide.]

I have installed FreeBSD 9.1 on my server (it's a virtualized qemu/kvm
environment, in case that matters) and during boot the following
messages appear:

    ntpd[766]: ntpd 4.2.4p5-a (1)
    ntpd[767]: bind() fd 23, family AF_INET6, port 123, scope 2, addr fe80::216:36ff:fe74:2076, mcast=0 flags=0x11 fails: Can't assign requested address
    ntpd[767]: unable to create socket on re0 (3) for fe80::216:36ff:fe74:2076#123

This happens with a GENERIC kernel. I have not touched any IPv6
related configuration after install, so everything should be in the
default state. Neither have I changed the ntp/ntpd configuration.

Although I could find some threads where people were discussing the
same problem, none of the mentioned suggestions fixed this for me.

In particular I tried setting

    ipv6_activate_all_interfaces="YES"

in rc.conf -- didn't fix the problem.

According to ifconfig, my interfaces, re0 in particular, have IPv6
addresses associated to them. So why would it fail that a process
tries to bind to it? Note that I'm rather unexperienced wrt IPv6.

Would be great if somebody could give me a hint into the right
direction. Anybody else experiencing this? Thank you very much!
