Note, the pool encourages 17# users with a static IP and good upstream NTP servers to add a server 18# to the pool. See http://www.pool.ntp.org/join.html if you are interested. 19# 20# The option `iburst' is used for faster initial synchronisation. 21# The option `maxpoll 9' is used to prevent PLL/FLL flipping on FreeBSD. 22# 23server 0.freebsd.pool.ntp.org iburst maxpoll 9 24server 1.freebsd.pool.ntp.org iburst maxpoll 9 25server 2.freebsd.pool.ntp.org iburst maxpoll 9 26#server 3.freebsd.pool.ntp.org iburst maxpoll 9 27 28# 29# If you want to pick yourself which country's public NTP server 30# you want sync against, comment out the above servers, uncomment 31# the next ones and replace CC with the country's abbreviation. 32# Make sure that the hostnames resolve to a proper IP address! 33# 34# server 0.CC.pool.ntp.org iburst maxpoll 9 35# server 1.CC.pool.ntp.org iburst maxpoll 9 36# server 2.CC.pool.ntp.org iburst maxpoll 9 37 38# 39# Security: Only accept NTP traffic from the following hosts. 40# The following configuration example only accepts traffic from the 41# above defined servers. 42# 43# Please note that this example doesn't work for the servers in 44# the pool.ntp.org domain since they return multiple A records. 45# (This is the reason that by default they are commented out) 46# 47#restrict default ignore 48#restrict 0.pool.ntp.org nomodify nopeer noquery notrap 49#restrict 1.pool.ntp.org nomodify nopeer noquery notrap 50#restrict 2.pool.ntp.org nomodify nopeer noquery notrap 51#restrict 127.0.0.1 52#restrict -6 ::1 53#restrict 127.127.1.0 54 55# 56# If a server loses sync with all upstream servers, NTP clients 57# no longer follow that server.
