===User and network (WiFi)===
 
Connect to DTU Wifi
 
* use NTP (network time protocol) with DTU network (require ntp and ntpdate packages)
* connect to DTU network without showing secret password
 
Instructions here [[Network setup]]
 
===Enable autostart===
 
====Display of IP====
 
Start app to display IP on Regbot display, log CPU temperature and synchronize hostname
 
Make an on-rebbot script in the home directory
 
cp ~/svn/robobot/setup/on_reboot.bash ~/
 
This file is something like:
 
#!/bin/bash
# script to start applications after a reboot
#
# run the app to show IP of raspberry on the Teensy display.
mkdir -p /home/local/svn/log
cd /home/local/svn/log
# save the last reboot date
echo "Rebooted" >> rebootinfo.txt
date >> rebootinfo.txt
../robobot/ip_disp/build/ip_disp &
# save PID for debugging
echo "ip_disp started with PID:" >> rebootinfo.txt
pgrep -l ip_disp >> rebootinfo.txt
exit 0
 
Use crontab to run this script at reboot
 
crontab -e
 
If asked, select the preferred editor (suggesting nano).
 
Add this line at the end:
@reboot /home/local/on_reboot.bash
 
====Hostname update====
 
A script updates the Raspberry Pi hostname, with the name in ''~/svn/log/robotname''.
The script ''rename_host.bash'' is:
#!/bin/bash
hn=`hostname`
f="/home/local/svn/log/robotname"
if [ -f $f ];
then
  nn=`cat $f`
  yy= $(expr length $nn)
  if [ $yy -gt 2 ];
  then
    if [ $hn != $nn ];
    then
      hostnamectl set-hostname $nn
      # seems like /etc/hosts is not updated, but /etc/hostname is
      sed -i "s/$hn/$nn/g" /etc/hosts
    else
      echo Same hostname, all is fine.
    fi
  fi
else
  echo "File >" $f "< not found."
fi
 
The script needs to be run as root, it is therefore set to run as part of the boot process.
 
Create the script in /etc/init.d
 
sudo nano /etc/init.d/host_rename.sh
 
Enter the following lines into the new file
 
#!/bin/bash
bash /home/local/svn/robobot/setup/rename_host.bash
 
Make the file executable and add it to run-level 2 (before networking is started)
 
sudo chmod +x /etc/init.d/host_rename.sh
sudo ln -s /etc/init.d/host_rename.sh /etc/rc2.d/S99host_rename
 
The script is then executed when the Raspberry boots, and if the hostname does not match that of the Teensy, then the hostname is modified.
