I have a mac mini running OS X Server (Mavericks, 10.9.1 - latest Server.app) and I keep getting these error messages in them system logs every few minutes. I am not sure if there is a real problem or not.

Jan 22 08:20:54 myosxserver.com ntpd[???]: unable to create socket on en0 (????) for ipv6here

Is there really something wrong? or can I disable ntpd from logging these?

  • did you change anything in the ntp.conf? Do you have ipv6 disabled on the ethernet interface? – dfc Jan 22 '14 at 22:15
  • no I have not, and I just checked and it seems to have the europe apple server as expected (?) in one line as: server time.euro.apple.com. I believe the ipv6 is enabled on the ethernet as it has an ipv6 address when I look in the network pref. – Kash Jan 22 '14 at 22:56
  • I take it ipv6here was the ipv6 address? did you replace something with (????)? What is the output of sudo lsof -n -i UDP:123 – dfc Jan 22 '14 at 23:47

I believe I corrected this by using this in the terminal:

sudo ntpdate -u time.euro.apple.com
  • ntpdate is now deprecated. If /etc/ntp.config contains "time.euro.apple.com" then sudo ntpd -q does the same thing and is the recommended alternative. – Tony Williams Jan 25 '14 at 12:22
  • Thanks, I had done that too, I guess this one must have done the trick. – Kash Jan 25 '14 at 15:39

I fixed this issue by adding the following line to /etc/ntp.conf

interface ignore ipv6

and then restarting ntpd
