[CentOS] NTP problems
My server is supposed to be using ntp, with nothing changed from the defaults set up by CentOS5. However, daily I see log entries like Total synchronizations 2 (hosts: 2) **Unmatched Entries** sendto(193.6.222.20) (fd=21): Invalid argument: 1 time(s) sendto(141.89.226.2) (fd=21): Invalid argument: 1 time(s) Does this mean that ntp is failing? I assume so, and if so, how do I change the sources to something that will work?

I have had this problem also a long time ago. The following command works for me in /etc/ppp/ip-up.local. # restart time service cause of new ip from provider /etc/rc.d/init.d/ntpd restart regards Olaf ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Thanks for replying. No, the server is on a fixed IP, internally and externally.

Re: [CentOS] NTP problems
Anne, please check your /etc/ntp.conf for the server statement; CentOS original is server 0.rhel.pool.ntp.org server 1.rhel.pool.ntp.org server 2.rhel.pool.ntp.org These 2 server ips you listed do not belong to this pool (you can check via dns), and resolved backwardly their names do not sound like they are ntp servers. You should find out why your ntp tries to send to them (and what). The total synchronizations ... line at least seems to say that your ntp sync works - you could check that with ntpdate against a server from the above pool to be sure. Dirk --On 15.

I wonder if it was ipv6 lines? I have # cat /etc/ntp.conf restrict default kod nomodify notrap nopeer noquery restrict 127.0.0.1 restrict 192.168.0.0 mask 255.255.255.0 nomodify notrap restrict 0.de.pool.ntp.org mask 255.255.255.255 nomodify notrap noquery restrict 1.de.pool.ntp.org mask 255.255.255.255 nomodify notrap noquery restrict 2.de.pool.ntp.org mask 255.255.255.255 nomodify notrap noquery restrict 3.de.pool.ntp.org mask 255.255.255.255 nomodify notrap noquery restrict default kod nomodify notrap nopeer noquery restrict -6 default kod nomodify notrap nopeer noquery server 127.127.1.0 server 0.de.pool.ntp.org server 1.de.pool.ntp.org server 2.de.pool.ntp.org server 3.de.pool.ntp.org server 0.centos.pool.ntp.org server 1.centos.pool.ntp.org server 2.centos.pool.ntp.org server 127.127.1.0 # local clock driftfile /var/lib/ntp/drift keys /etc/ntp/keys fudge 127.127.1.0 stratum 10 broadcastdelay 0.008 fudge 127.127.1.0 stratum 10 driftfile /var/lib/ntp/drift keys /etc/ntp/keys I don't have a broadcastdelay line, as far as I can see. You have fare more 'restricts' than I have, but apart from that the main difference seems to be the presence of two IPV6 lines. What do you think?
