If you're looking for a good clock-setting engine you can run ntpdate from cron to set your clock. It is a one-shot deal, and can be run once per day or whatever is comfortable for your situation. Example follows: ==== #!/bin/sh # # Is internet connection active? result=$(cinternet -i ppp0 -s | grep connect) #Test to see if the value is not NULL if [ -n "$result" ] then #Yes... Update hdwe clock ntpdate -b -u 132.246.168.148 #open server IP #No... so just exit else exit 0 fi ==== Works like a champ. Thanks to a couple other suse-linux-e members who dropped the ideas on this list. :-)

It is good to augment ntpdate with adjtimex. Once you determine a good frequency adjustment to use, you can stick a call to adjtimex with that frequency adjustment in your /etc/rc.d/boot.local and have your time very accurate in between calls to ntpdate as well. My firewall keeps time accurate to better than .05 seconds a day using adjtimex, and without it, it gains 2 seconds a day. (See man adjtimex).

Well, I opened the 123 UDP port using YAST->System->Editor for /etc/sysconfig Files->Network->Firewall->SuSEfirewall2->FW_SERVICES_EXT_UDP='123' Now what is the appropriate configuration of /etc/ntp.conf ? I start the xntpd using the following line in the boot.local /usr/sbin/ntpd -p /var/lib/ntp/var/run/ntp/ntpd.pid -u ntp:nogroup -i /var/lib/ntp -c /etc/ntp.conf -c /etc/ntp.conf What else should i do to put ntp into work? ----- Original Message ----- From: "Mark Gray" To: Sent: Friday, September 03, 2004 10:28 PM Subject: Re: [SLE] NTP & SUSE 9

At the minimum, you just need to add one or more time servers to connect to in your /etc/ntp.conf file, something like (use whichever public time servers that you prefer, hopefully one that is close to your machine in terms of number of network hops): server clock.isc.org server clock.llnl.gov See the comments in the file for info. You can comment out the server definitions for 127.x.x.x.

I start the xntpd using the following line in the boot.local

/usr/sbin/ntpd -p /var/lib/ntp/var/run/ntp/ntpd.pid -u ntp:nogroup -i /var/lib/ntp -c /etc/ntp.conf -c /etc/ntp.conf

That's not the proper way to do it on a SuSE 9 box. To enable ntpd, just do the following as root: $ chkconfig -a xntpd $ rcxntpd start And then ntpd will be activated. It will also auto-start each time you boot. -Ti

There are no obvious errors, but the time set 0.000000 s is a bit strange. I would expect at least a little deviation from 0 (how likely is that your current system time is accurate within 6 decimal points to actual)? At any rate, to check that your machine can talk to the time server, you can type the following command as root: $ ntpdate -u timeserver where timeserver is the fully qualified domain name or IP number of a public time server. If this doesn't produce an error then you can assume that all is well. This command actually causes your local date/time to be adjusted to match that of the time server. The /etc/init.d/xntpd startup script actually does this for you once when your system starts, and then ntpd will keep things in sync afterwards. When I do this on my machine I get: $ ntpdate -u clock.isc.org 4 Sep 03:52:44 ntpdate[15387]: adjust time server 204.152.184.72 offset -0.000295 sec -Ti

Still no ntp.drift has been created.

Please trim your replies.

It does not appear to be connecting to any authority. Did you enable ntp or port 123 in your firewall?

How old the computer is, has nothing to do with it. It all depends on the accuracy of the crystal used in the clock. Some are worse than others.

You can't unless you expect both PC's to have -exactly- the same clock speed, fat chance of that happening. Too many electronic parts with tolerances of +- 10%. Ken

Hi, The driftfile contents are evidence that the NTP client is doing its job: Keeping the local H/W clock set to UTC standard. If the local clock didn't drift there would be no need for NTP! If you want to have no drift you will have to find a Motherboard Mfgr that supplies an atomic clock on the board.

Or get your own accurate time source, such as a GPS receiver. There are also short wave receivers available, that allow a computer to sync to WWV. Heathkit sold a couple several years ago, but I've seen others since then. As I recall, the Heathkit would keep a computer accurate to within 10 mS.

It would be nice, if we could get a cesium atomic clock on a chip. ;-)

Running ntpd should automagically adjust for drift. As I understand it, ntpdate doesn't. I use ntp on both my desktop systems, as they're always connected to the internet. But I use ntpdate on my notebook, as it usually is turned off. I have added an item to my desktop menu, to run ntpdate. John wrote:

There is no CORRECT value. It measures how much your individual clock drifts and as such asking if the value is correct is like asking if your fingerprint is correct. -- _____________________________________ John Andersen

You are not reading what they tell you. ¿How do you tell if the drift value is correct or not? There is no such thing. If, when using the ntp daemon the time is kept accurate, then the drift value can be assumed to be correct and doing its job. The value will be different on any computer. -- Cheers, Carlos Robinson
