On a cold boot of my desktop machine, the ntpd service remains unsynchronized unless I manually restart the service at some later point. All configuration files are unchanged from the defaults. Here's what I see in /var/log/messages - Jul 25 17:59:12 ntpd[2159]: ntpd 4.2.4p4 Mon Apr 7 17:32:53 UTC 2008 (1) Jul 25 17:59:12 ntpd[2160]: precision = 1.000 usec Jul 25 17:59:12 ntpd[2160]: Listening on interface #0 wildcard, 0.0.0.0#123 Disabled Jul 25 17:59:12 ntpd[2160]: Listening on interface #1 wildcard, ::#123 Disabled Jul 25 17:59:12 ntpd[2160]: Listening on interface #2 lo, ::1#123 Enabled Jul 25 17:59:12 ntpd[2160]: Listening on interface #3 lo, 127.0.0.1#123 Enabled Jul 25 17:59:12 ntpd[2160]: kernel time sync status 0040 Jul 25 17:59:12 ntpd[2160]: frequency initialized -24.988 PPM from /var/lib/ntp/drift Jul 25 18:04:13 ntpd[2160]: Listening on interface #4 eth0, fe80::211:11ff:fed2:8da5#123 Enabled Jul 25 18:04:13 ntpd[2160]: Listening on interface #5 eth0, 192.168.1.100#123 Enabled Jul 25 22:33:08 ntpd[2160]: ntpd exiting on signal 15 Jul 25 22:33:08 ntpd[32691]: ntpd 4.2.4p4 Mon Apr 7 17:32:53 UTC 2008 (1) Jul 25 22:33:08 ntpd[32692]: precision = 1.000 usec Jul 25 22:33:08 ntpd[32692]: Listening on interface #0 wildcard, 0.0.0.0#123 Disabled Jul 25 22:33:08 ntpd[32692]: Listening on interface #1 wildcard, ::#123 Disabled Jul 25 22:33:08 ntpd[32692]: Listening on interface #2 lo, ::1#123 Enabled Jul 25 22:33:08 ntpd[32692]: Listening on interface #3 eth0, fe80::211:11ff:fed2:8da5#123 Enabled Jul 25 22:33:08 ntpd[32692]: Listening on interface #4 lo, 127.0.0.1#123 Enabled Jul 25 22:33:08 ntpd[32692]: Listening on interface #5 eth0, 192.168.1.100#123 Enabled Jul 25 22:33:08 ntpd[32692]: kernel time sync status 0040 Jul 25 22:33:08 ntpd[32692]: frequency initialized -24.988 PPM from /var/lib/ntp/drift Jul 25 22:33:14 ntpd_initres[2170]: parent died before we finished, exiting Jul 25 22:37:25 ntpd[32692]: synchronized to 65.111.164.224, stratum 2 Jul 25 22:37:25 ntpd[32692]: kernel time sync status change 0001 Jul 25 22:46:08 ntpd[32692]: synchronized to 69.36.240.252, stratum 2 Note the long time of no synchronization after first startup, until I restart the service at 22:33:08. Also, the ntpdate service is off and I am using NetworkManager to manage my connectivity, if that makes any difference. Thanks again for your help.
I managed to reproduce the problem and have a patch that should fix it. It's caused by not reloading /etc/resolv.conf after NetworkManager update. Thanks for the report.
