+ | ===== Configuration ===== | ||
+ | We are using the default configuration that Debian/CentOS ships with. This is primarily a client configuration -- we allow other systems only to get the current time; they may not query any further information. (This is limited via the ''restrict'' keyword.) The daemon runs primarily in order to sync the system's time with the upstream NTP servers. | ||

+ | The configuration file points to multiple upstream NTP servers within [debian/centos].pool.ntp.org. | ||
