Keeping time is important. Especially when debugging an issue between servers. It is a pain comparing logfiles with a time skew. For that reason we will configure two NTP servers that all clients will synchronize their time to.

Configuring a redundant NTP server does not really make any sense. The DHCP server sends option ntp-servers to the DHCP clients, so if one NTP server is down, then the other will get the request instead.


The NTP servers will have fixed IP-addresses. That is configured in the DHCP servers list of statically assigned IP-adresses by using the Domains MAC address.


Set the Time

apt-get install ntpdate
ntpdate pool.ntp.org
hwclock --systohc

Install the NTP Daemon

apt-get install ntp

None: NTP (last edited 2017-12-13 13:52:18 by Kristian Kallenberg)
