ntpdate issues?

[Tim Newsham]

Hi, I'm trying to run ntpdate from domain zero and getting
weird results.  This used to work (prior to using xen).  Is
this related to xen at all or an entirely unrelated issue?

Queries seem to work:
   # ntpdate -q time-b.nist.gov
   Looking for host time-b.nist.gov and service ntp
   host found : time-b.nist.gov
   server 129.6.15.29, stratum 1, offset 41.820087, delay 0.17027
   17 Mar 10:22:02 ntpdate[1030]: step time server 129.6.15.29 offset
   41.820087 sec

Debug too:
   # ntpdate -d time-b.nist.gov

   17 Mar 10:22:35 ntpdate[1031]: step time server 129.6.15.29 offset

But actually setting the date fails:
   # ntpdate time-b.nist.gov
   Looking for host time-b.nist.gov and service ntp
   host found : time-b.nist.gov
   17 Mar 10:23:39 ntpdate[1032]: no server suitable for synchronization
   found

Setting the date manually does work though:
   # date 03171024.50
   Thu Mar 17 10:24:50 HST 2005

Weird. ntpdate works fine for me.

What distro is this?

Please can you try strace'ing it and see if there's any set time calls
that are failing.

Don't know, but... Does ntpdate -u work?

That was the solution.  -q and -d used a nonprivileged port
where the normal update used a privileged port.
