We're currently running ntpd on several FreeBSD machines (FreeBSD versions 4.0 and 4.3 and ntp versions 4.0.9x). For some reason, although all of them are getting their time from the same sources, one of them consistently drifts and so advertises the wrong time. I have noticed that the /etc/ntp.drift files on the machines are different but haven't gotten my mind around what that actually means, the two correct ones have ntp.drift of -7.731, -6.280 and the off one has -500.00. Here's the /etc/ntp.conf file (same on all three except for the peer statements): driftfile /etc/ntp.drift disable auth monitor server time.ots.utexas.edu prefer server tick.uh.edu server tick.greyware.com peer dnscache1.ots.utexas.edu peer dnscache3.ots.utexas.edu peer ntp.cc.utexas.edu # by default, don't trust or allow modification restrict default notrust nomodify # Restrict to only our networks restrict 128.83.0.0 mask 255.255.0.0 nomodify restrict 146.6.0.0 mask 255.255.0.0 nomodify restrict 129.116.0.0 mask 255.255.0.0 nomodify restrict 129.110.0.0 mask 255.255.0.0 nomodify restrict 206.77.62.0 mask 255.255.255.0 nomodify restrict 206.77.63.0 mask 255.255.255.0 nomodify restrict 127.0.0.1 restrict 128.83.3.90 Any thoughts/suggestions/pointers?
