=====NTP-server=====
Let's start keeping time on our server. Otherwise logging and Kerberos won't work as expected and you might forget your coffee break!

If you have a static IP and a somewhat reliable internet connection, you might consider joining the pool.ntp.org initiative. See http://www.pool.ntp.org/ for more information.

====Pre-installation====
Check your timezone settings by issuing: 
  tzconfig

====Installation====
Install the software:

  apt-get install ntp-server ntp-doc

====Configuration====
Adjust /etc/ntp.conf for the ntp-servers you want to sync to. Remember to check the policy for their usage! If you want more info about the Debian NTP packages, check the docs at /usr/share/doc/ntp and /usr/share/doc/ntp-doc

/etc/ntp.conf
<code>
driftfile /var/lib/ntp/ntp.drift
statsdir /var/log/ntpstats/
statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable
#
# pool.ntp.org maps to more than 100 low-stratum NTP servers.
# Your server will pick a different set every time it starts up.
#  *** Please consider joining the pool! ***
