# Welcome to the chrony configuration file. See chrony.conf(5) for more # information about usuable directives. # This will use (up to): # - 4 sources from ntp.ubuntu.com which some are ipv6 enabled # - 2 sources from 2.ubuntu.pool.ntp.org which is ipv6 enabled as well # - 1 source from [01].ubuntu.pool.ntp.org each (ipv4 only atm) # This means by default, up to 6 dual-stack and up to 2 additional IPv4-only # sources will be used. # At the same time it retains some protection against one of the entries being # down (compare to just using one of the lines).
