.TH chrony.conf 5 "@MAN_DATE@" "chrony @VERSION@" "Configuration Files"

.SH NAME
|
|
chrony.conf \- chronyd configuration file
|
|
|
|
.SH SYNOPSIS
|
|
.B @SYSCONFDIR@/chrony.conf
|
|
|
|
.SH DESCRIPTION
|
|
\fIchrony\fR is a pair of programs for maintaining the accuracy of computer
|
|
clocks. \fIchronyd\fR 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 \fIchrony\fR. The (compiled-in) default location
|
|
for this file is \fB@SYSCONFDIR@/chrony.conf\fR. Assuming that your NTP
|
|
servers are called `foo.example.net', `bar.example.net' and `baz.example.net',
|
|
your \fBchrony.conf\fR file could contain as a minimum
|
|
|
|
.EX
|
|
server foo.example.net
|
|
server bar.example.net
|
|
server baz.example.net
|
|
.EE
|
|
|
|
However, you will probably want to include some of the other directives
|
|
described in detail in the documentation supplied with the distribution
|
|
(\fIchrony.txt\fR and \fIchrony.texi\fR). 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
|
|
|
|
.EX
|
|
server foo.example.net iburst
|
|
server bar.example.net iburst
|
|
server baz.example.net iburst
|
|
driftfile @CHRONYVARDIR@/drift
|
|
makestep 1.0 3
|
|
rtcsync
|
|
.EE
|
|
|
|
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
|
|
|
|
.EX
|
|
pool pool.ntp.org iburst
|
|
driftfile @CHRONYVARDIR@/drift
|
|
makestep 1.0 3
|
|
rtcsync
|
|
