ntpdate on Linux

Post by Leiji Li » Fri, 20 Dec 2002 09:15:57



Hi,
I have a question about synchronizing system clock on Linux. I used
/usr/sbin/ntpdate 192.43.244.18 (and other about 10 NTP sites around US),
but got following message:

ntpdate[4065]: no server suitable for synchronization found

I tried "ntpdate -q 192.43.244.18" to enable debugging mode, and got message
like:

ntpdate[4090]: step time server 192.43.244.18 offset -193.070745 sec

It seems OK under debugging mode. Why it is not able to adjust the time?
(The same command works fine on Solaris). Thanks,

I think Google knows, and so does the NTP FAQ.  Since the FAQ is a bit
confusing, I'll give you a link:
http://www.eecis.udel.edu/~ntp/ntpfaq/NTP-s-trouble.htm.

Please use Usenet as a last resort, not a replacement for Google.

Thanks for your information. I got what I want. I use "ntpdate -u
timeserver" instead of "ntpdate timeserver", and it works.

        So why are you bothering "comp.unix.admin" with it.  The topic of
"comp.unix.admin" is the administration of UNIX systems.  There are
specific newsgroups for the discussion of non UNIX systems such as
LINTEL/Windows/BSD/OpenVMS/MacOS/etc...  This isn't one of them.

        [followups set as appropriate]

                Happy to have cleared things up for you,
                                Don

this indicates that either you have ntpd running in which case you should
not be running ntpdate, or your packet filters are improperly configured as
is all too common of `out of the box' solutions for linux.

Or that low UDP ports are blocked, prehaps intentionally.

that's the improper configuration of which i spoke.  i should have been
more clear, that port 123 udp is involved -- thanks.
