NTP

Network time protocol, to keep clocks in sync. At DTU most clock sources are blocked, the clock source needs to be configured.

At DTU, edit /etc/ntp.conf, add ntp.ait.du.dk to server pool

...
# Use servers from the NTP Pool Project. Approved by Ubuntu Technical Board
# on 2011-02-08 (LP: #104525). See http://www.pool.ntp.org/join.html for
# more information.
pool ntp.ait.dtu.dk

sudo ntpdate -u ntp.ait.dtu.dk
