====== Programmeerimisserveri seadistamine ======

====== Kodulabori seadistamine ======

Esmalt pane igale kontrollerplaadi usb'le FTprog utiliidi abil seerianumber 

{{ :et:distancelab:setserial.png?100|}}

===== HLFlash paigaldamine =====

Järgida juhendit: http://home.roboticlab.eu/et/examples/setup/eclipse/install/linux

Paigaldada hlinit

Kui Kodulabori plaat ühendatud käivitada hlinit

Kasutamine:

Kui kasutad faili nime asemel "-" märki, siis loetakse fail sisse standard 
inputist (kasulik ssh'ga üle võrgu programmeerimisel).  

Mitme kontrolleri puhul saad faili nime taha lisada soovitud kontrolleri usb 
serial numbri.

===== Video streameri seadistamine =====

Mjpg streamer

Install the pre-requisites:

  $ sudo apt-get install g++ curl pkg-config libv4l-dev libjpeg-dev build-essential libssl-dev vim cmake imagemagick
 

Download mjpg-streamer

  $ wget https://github.com/shrkey/mjpg-streamer/raw/master/mjpg-streamer.tar.gz
  $ tar -xvf ./mjpg-streamer.tar.gz
 

Compile the mjpg-streamer

  $ cd mjpg-streamer
  $ make
  $ sudo make install
 

Run a test.

  $ sudo ./mjpg_streamer -i “./input_uvc.so” -o “./output_http.so -w ./www”

Seadista automaatne käivitumine

Install the mjpg-streamer

  $ sudo cp mjpg_streamer /usr/local/bin
  $ sudo cp output_http.so input_file.so /usr/local/lib/
  $ sudo cp -R www /usr/local/www

If the MJPG-streamer needs to be started automatically at system startup, you can create the configuration file /etc/init/mjpg_streamer.conf for Upstart :


  description "MJPG-streamer /dev/video0"
  start on runlevel [2345]
  stop on runlevel [016]
  script
     /usr/local/bin/mjpg_streamer -i "/usr/local/lib/input_uvc.so" -o "/usr/local/lib/output_http.so -w /usr/local/www/www" >> /var/log/mjpg_streamer_upstart.log 2>&1
  end script

The script for starting a multiple cameras:

  description "MJPG-streamer START"
  start on runlevel [2345]
  stop on runlevel [016]
  script
  /usr/local/bin/mjpg_streamer -b -i "/usr/local/lib/input_uvc.so -d /dev/video0 -r 1280x720" -o "/usr/local/lib/output_http.so -p 8080 -w /usr/local/www/www/" >> /var/log/mjpg_streamer_upstart.log 2>&1
  /bin/sleep 5
  /usr/local/bin/mjpg_streamer -b -i "/usr/local/lib/input_uvc.so -d /dev/video1 -r 1280x720" -o "/usr/local/lib/output_http.so -p 8081 -w /usr/local/www/www/" >> /var/log/mjpg_streamer_upstart.log 2>&1
  /bin/sleep 5
  /usr/local/bin/mjpg_streamer -b -i "/usr/local/lib/input_uvc.so -d /dev/video2 -r 1280x720" -o "/usr/local/lib/output_http.so -p 8082 -w /usr/local/www/www/" >> /var/log/mjpg_streamer_upstart.log 2>&1
  /bin/sleep 5
  /usr/local/bin/mjpg_streamer -b -i "/usr/local/lib/input_uvc.so -d /dev/video3 -r 1280x720" -o "/usr/local/lib/output_http.so -p 8083 -w /usr/local/www/www/" >> /var/log/mjpg_streamer_upstart.log 2>&1
  /bin/sleep 5
  end script
  
The script must be executable:

  sudo chmod u+x /etc/init/mjpg_streamer.conf

=====   Võtmepaari genereerimine =====

Kui remote masinas pole enne tehtud, siis teha esmalt kataloog:

  mkdir .ssh

Kauglabori veebiserveris www-data kasutaja alt:
  sudo -s
  su www-data
  bash


(kui korra juba tehtud võib vahele jätta)
  ssh-keygen -t rsa
  cat ~/.ssh/id_rsa.pub | ssh [remote-kasutaja]@[remote-masin] "cat - >> ~/.ssh/authorized_keys"
Kui key olemas, aga vana host, siis teha enne remove, nt:
  ssh-keygen -f "/var/www/.ssh/known_hosts" -R usora-artica.noip.me

Kontrollida, kas remote host õigused on paigas:
Kataloogi õigus:
  chmod 700 ~/.ssh
faili õigus:
  chmod 600 ~/.ssh/authorized_keys
