I'll include the ntp.conf configuration we use, as well relevant rc.conf portions, on a few of our production machines. There are some "FreeBSD-isms" in ntp.conf which are worth noting. I keep the comments around solely so I don't forget. :-) ntp.conf: # clock.isc.org # clepsydra.dec.com # # maxpoll 9 is used to work around PLL/FLL flipping, which # happens at exactly 1024 seconds (the default maxpoll value). # Another FreeBSD member recommended using 9 instead. # http://lists.freebsd.org/pipermail/freebsd-stable/2006-December/031512.html # server 204.152.184.72 iburst maxpoll 9 server 204.123.2.5 maxpoll 9 # Default: ignore all ntp queries from ALL other hosts restrict default ignore # Allow queries to/from the NTP hosts listed in "server" lines restrict 216.218.192.202 mask 255.255.255.255 restrict 216.218.254.202 mask 255.255.255.255 restrict 204.152.184.72 mask 255.255.255.255 restrict 204.123.2.5 mask 255.255.255.255 # Allow queries to/from localhost, used for ntpdc and other utils restrict 127.0.0.0 mask 255.0.0.0 # Allow queries to/from the local private network restrict 192.168.1.0 mask 255.255.255.0 nomodify rc.conf: ntpd_enable="yes" ntpd_sync_on_start="yes" Applicable process: root 652 0.0 0.1 3148 1564 ??
