I am trying to give IPv6 support for NTP server in my ntp scripts.

Yet i have set the IPv6 NTP server directly by giving its IP in ntp.conf and restart the ntpd .

Now in the logs of ntpq flash value become 1600 and stratum is set to 16 but the original stratum of this server is 4.

Then i tried whether ntpdate is running or not....and found that the ntpdate is not running.

Now how i can run ntpdate command or how i can correct the flash value..

Thanks in advance

    ntpdate is not a daemon that runs all the time, it's intended for interactive use or in scripts to poll an NTP server once. ntpd is the daemon process you need to look for. – Sven Apr 30 '16 at 10:37
  • Thanks for your response. Yes i know ntpdate is not a deamon its a command to quickly sync with ntp server..... Now back to the question,stratum of ntp server is 16 which might be due to flash=1600 in ntpq logs....now what can i do to be in sync with that NTP server – ajay Apr 30 '16 at 10:51
  • You cannot sync to a server at stratum 16, as it is itself not synced. – MadHatter Apr 30 '16 at 10:55
  • Thanks MadHatter sir for your response... The actual stratum of that server is 4....i confirmed it when i set that server by using its IPv4 address and when i am trying to set the same server using IPv6 then it is giving stratum = 16 which might be due to flash =1600 – ajay Apr 30 '16 at 11:02
  • So it's your client that's at stratum 16, when (and only when) you try to bind over ipv6? If so, are you sure you've got end-to-end v6 connectivity? There's no firewall on the server blocking v6 connections? – MadHatter Apr 30 '16 at 11:20
