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.

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?
