Network setup
Access using ssh and username local
ssh -X local@<IP>
ask for the password (or look on the course page)
Packages to install
Install:
ntp ntpdate openssh-server git libreadline-dev sudo apt install ntp ntpdate openssh-server git libreadline-dev
Install ros-melodic-desktop-full, follow instructions in: http://wiki.ros.org/melodic/Installation/Ubuntu up to section 2. Tutorials.
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.
