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
...

Sync time

sudo ntpdate -u ntp.ait.dtu.dk

Should work in and around DTU - see also NTP howto for more details.

WiFi network

Now open wpa_supplicant.conf

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

If you added an wifi access point, it probably looks something like this

network={
       ssid="device"
       key_mgmt=NONE
}

or

network={
       ssid="tdc432"
       psk="secret_password"
       key_mgmt=WPA-PSK
       id_str=home

}

You can add any number of the "network" groups for all the networks you get across If you don't like the network password to be visible, see guide below.
