NAME chrony.conf - chronyd configuration file
SYNOPSIS /etc/chrony/chrony.conf
DESCRIPTION chrony is a pair of programs for maintaining the accuracy of computer clocks. chronyd is a background daemon program that can be started at boot time. Assuming that you have found some servers, you need to set up a configuration file to run chrony. The (compiled-in) default location for this file is /etc/chrony/chrony.conf. Assuming that your NTP servers are called `foo.example.net', `bar.example.net' and `baz.example.net', your chrony.conf file could contain as a minimum server foo.example.net server bar.example.net server baz.example.net However, you will probably want to include some of the other directives described in detail in the documentation supplied with the distribution (chrony.txt and chrony.texi). The following directives may be particularly useful : `driftfile', `makestep', `rtcsync'. Also, the `iburst' server option is useful to speed up the initial synchronization. The smallest useful configuration file would look something like server foo.example.net iburst server bar.example.net iburst server baz.example.net iburst driftfile /var/lib/chrony/drift makestep 10 3 rtcsync When using a pool of NTP servers (one name is used for multiple servers which may change over time), it's better to specify them with the `pool' directive instead of multiple `server' directives. The configuration file could in this case look like pool pool.ntp.org iburst driftfile /var/lib/chrony/drift makestep 10 3 rtcsync
