Pick a machine. Configure that machine as your reference. Give it an artificially high stratum number even when not externally synchronized. I suspect that would work for you. (Of course, for about $350 you can find HP GPS based time references you can use on that reference computer to keep it exactly on time.) {^_^} ----- Original Message ----- From: "Brian T. Brunner" <brian.t.brunner@xxxxxxxxxxxxxxx> How to keep two or more linux (RH7.2-RH9) systems time-synched? I have checked into ntp/ntpd and found it to be broken too far for mere words. It's avowed purpose is to find the One True UTC, I have an isolated gaggle of machines on a private net that need to stay together regardless of how far that 'together' drifts from WWV or some net-readable atomic clock. Given a gaggle with no net connect to other machines outside the gaggle, ntp fails to perform, and fails to explain why. ntp's documentation frustrates and obfuscates. Unless there is an ntp HOWTO for dummies, I've dumped ntp. What other network time synch programs are available?
