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? Anne -------------- next part -------------- A non-text attachment was scrubbed...
