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 `a.b.c' and `d.e.f', your \fBchrony.conf\fR file could contain
as a minimum
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
server a.b.c
server d.e.f
server g.h.i
.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', `generatecommandkey', `keyfile', `makestep'.
Also, the `iburst' server option is useful to speed up the initial
synchronization. The smallest useful configuration file would look something
like
particularly useful : `driftfile', `makestep', `rtcsync'. Also, the `iburst'
server option is useful to speed up the initial synchronization. The smallest

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 in order to allow \fIchronyd\fR to
replace unreachable or bad servers automatically. The configuration file could
in this case look like
.EX
pool pool.ntp.org iburst
driftfile @CHRONYVARDIR@/drift
makestep 10 3
rtcsync
.EE
