Is he using a virtual system? Is that loss constant ( or is it sometimes 1 sec, sometimes 3 sec sometimes nothing). He is eitehr running a virtual machine, in which case he should not be using ntpd, or his operating system is doing an attrocious job of setting the system time rate of his clock. _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
