+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

+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
