How to confirm/deny ntp is working?
Hi folks, I've read several different sources on setting up ntp on FreeBSD (I'm using 8.1), and they seem to vary a little, so I'm confused about how DO you set this up, and how do you confirm/deny that it's working? I've modified my /etc/ntp.conf file by commenting out: #server 0.freebsd.pool.ntp.org iburst maxpoll 9 #server 1.freebsd.pool.ntp.org iburst maxpoll 9 #server 2.freebsd.pool.ntp.org iburst maxpoll 9 #server 3.freebsd.pool.ntp.org iburst maxpoll 9 and changing them to read (I'm in the U.S.): server 0.US.pool.ntp.org iburst maxpoll 9 server 1.US.pool.ntp.org iburst maxpoll 9 server 2.US.pool.ntp.org iburst maxpoll 9 I have confirmed that I can ping these servers. I've added ntpd_enable="YES" and ntpd_sync_on_start="YES" to /etc/rc.conf and rebooted the server. 1.) Do I need to manually create the "driftfile" (/var/db/ntpd.drift)? 2.) Do I need to manually create the logfile (/var/log/ntp.log)? 3.) How do you confirm that FreeeBSD is, in fact, keeping time?

Re: How to confirm/deny ntp is working?
you may want add to your ntpd.conf:
driftfile /your/drift
logfile /your/log
to confirm, you can change your system date, and see wether it comes back to
normal

If ntp's been running for a while, one of them should have an asterisk next to it (this is the one with which the system is currently synchronizing) and the "offset" column should show a fairly small number, usually within +/- 100 ms. For example, here's the output from my machine: remote refid st t when poll reach delay offset jitter == +cheezum.mattnor 24.56.178.1402 u 803 1024 377 79.195 -39.637 7.575 *dione.cbane.org 66.220.9.122 2 u 844 1024 377 34.034 -41.063 8.513 LOCAL(0).LOCL. 10 l 45 64 3770.0000.000 0.004 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"

Kevin> Just c'suped to 8 recently; mergemaster gave me a new ntp.conf and Kevin> this is the exact stuff in there ;-) Uh, why. Looks like the Right Thing is already in there: server 0.freebsd.pool.ntp.org iburst maxpoll 9 server 1.freebsd.pool.ntp.org iburst maxpoll 9 server 2.freebsd.pool.ntp.org iburst maxpoll 9 #server 3.freebsd.pool.ntp.org iburst maxpoll 9 This conforms with: http://www.pool.ntp.org/en/vendors.html specifically: Get your vendor zone To allow you to use the pool as the default time service in your application, we will set you up with special hostnames, for example 1.vendor.pool.ntp.org, 2.vendor.pool.ntp.org and 3.vendor.pool.ntp.org. You must absolutely not use the default pool.ntp.org zone names as the default configuration in your application or appliance. You can apply for a vendor zone here on the site. So the problem is that the original poster changed it *away* from the freebsd subdomains to the *us* subdomains. This is neither necessary nor advised. That's what I was complaining about. -- Randal L.
