HP-UX NTP client to Windows NTP server

[Matthias Oswald]

Hello,
Im trying to sync time on HP-UX server to the Windows domain controller.
When starting xntp daemon, I get the error message

ntpdate[1331]: no server suitable for synchronization found

I can ping the domain controller from Unix.
Anything special to configure for this ?

Thanks,
Matthias

I really doubt that you can use Windows as time source for Unix, windows uses SNTP, a "small" version of NTP.

See the following article:

http://www.microsoft.com/technet/itsolutions/cits/interopmigration/unix/usecdirw/21wsdsu.mspx

"Note: If there is no local time service for your UNIX hosts, it is recommended that you create one. This local computer should synchronize to the external time source, and all the other local computers should synchronize to it. This is both more efficient and more respectful of the higher tier providers who will not be inundated with synchronization requests."


So, Microsoft recommends the use of ONE unix server as NTP server (synchronized with Internet) for other unix clients.

unix can sync time using ntp from a Windows server - my Tru64 ntp client works OK. Depending on the version of Windows, some use ntp v1 another uses v3. I had to switch ntp version in my ntp.conf after a Windows upgrade.
ie change entry in ntp.conf from:

server 10.214.11.3 version 1

to

server 10.214.11.3 version 3
