Before you begin to install OpenCV
==Install Library package==

<source lang=cli>
sudo apt-get install build-essential cmake pkg-config -y
sudo apt-get install Image I/O libraries -y
sudo apt-get install libjpeg62-dev libtiff4--dev libjasper-dev -y
sudo apt-get install the GTK dev library -y
sudo apt-get install libgtk2.0-dev -y
sudo apt-get install Video I/O libraries -y
sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev -y
sudo apt-get install libdc1394-22-dev libxine-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev -y
sudo apt-get install python-dev python-numpy -y
sudo apt-get install libtbb-dev -y
sudo apt-get install libqt4-dev -y
</source>
==Install OpenCV==
Make the OpenCV directory
<source lang=cli>
mkdir /etc/OpenCV/
</source>
Change directory to OpenCV and download OpenCV in the directory
<source lang=cli>
cd /etc/OpenCV/
wget http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.2/OpenCV-2.4.2.tar.bz2
tar -xvf OpenCV-2.4.2.tar.bz2
</source>

Make the sub-directory build in the OpenCV folder and configure OpenCV with the command cmake.
<source lang=cli>
cd OpenCV-2.4.2
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..
</source>

Finally install OpenCV using the make and make install commands
<source lang=cli>
make
sudo make install
</source>

Cluster der kan alt/Install DNS server

2013-11-06T12:15:26Z

Thni: /* Step six: Verify domain and DNS entries */

==Installer DNS Server==
Install DNS server by download and install the package
<source lang=cli>
apt-get install bind9
</source>

==Configure DNS (Bind9)==
First we will edit these 3 files.
*/etc/bind/named.conf.local
*/etc/bind/named.conf.options
*/etc/resolvconf/resolv.conf.d/base

Second we will create these 2 files.
*/etc/bind/zones/dka.local.db
*/etc/bind/zones/rev.0.0.10.in-addr.arpa

===First step: add domain zone – dka.local===
Enter the named.conf.local file
<source lang=cli>
nano /etc/bind/named.conf.local
</source>
Add the entire to the file
<source lang=cli>
# Our Domain zone
zone "dka.local." {
type master;
file "/etc/bind/zones/dka.local.db";
};

# For reverse DNS
zone "0.0.10.in-addr.arpa" {
type master;
file "/etc/bind/zones/rev.0.0.10.in-addr.arpa.db";
};

</source>

===Secund step: Add the DNS servers from your ISP===
Enter the named.conf.options file
<source lang=cli>
nano /etc/bind/named.conf.options
</source>
Delete or comment the following
<source lang=cli>
dnssec-validation auto;

auth-nxdomain no; # conform to RFC1035
listen-on-v6 { any; };
};
</source>
Add the following to the bottom of the file
<source lang=cli>
forwarders {
172.16.4.66;
};

auth-nxdomain no; # conform to RFC1035
listen-on-v6 { any; };
listen-on { any; };

allow-query { 127.0.0.1; 172.16.4.66/24; 10.0.0.0/24;};
};

</source>
*NOTE: Be aware of which IP segment you are in. 172.16.4.66 = Hovedforløb 172.16.2.50,172.16.2.51 = Grundforløb

===Third step: Modify the resolv.conf file ===
Enter the resolv.conf.d/base file
<source lang=cli>
nano /etc/resolvconf/resolv.conf.d/base
</source>
Add the following lines
<source lang=cli>
nameserver 172.16.4.66
nameserver 10.0.0.1
domain dka.local
search dka.local
</source>

===Fourth step: Define zones===
First make the directory /etc/bind/zones
<source lang=cli>
mkdir /etc/bind/zones
</source>
Second make the file dka.local.db
<source lang=cli>
nano /etc/bind/zones/dka.local.db
</source>
Add the following text to the newly created file
<source lang=cli>
; BIND data file for local loopback interface
;
$TTL 604800
@ IN SOA ns.dka.local. root.dka.local. (
8 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS ns.dka.local.
ns IN A 10.0.0.1
ubuntu IN A 10.0.0.21
</source>
NOTES:
*The TTL or time to live is set for 3 days
*The ns.mydomain.com nameserver is defined
*Ubuntudesktop, pc and gateway are entered as an A record
*An alias of www is assigned to ubuntudesktop using CNAME

===Step five: Create a “rev.0.0.10.in-addr.arpa” file for reverse lookup===
Create the rev.0.0.10.in-addr.arpa file
<source lang=cli>
nano /etc/bind/zones/rev.0.0.10.in-addr.arpa
</source>
Add the following text
<source lang=cli>
$TTL 3D
@ IN SOA ns.dka.local. admin.dka.local. (
2007062001
28800
604800
604800
86400
)
IN NS ns.dka.local.
10 IN PTR node1.dka.local
10 IN PTR node2.dka.local
10 IN PTR node3.dka.local
10 IN PTR node4.dka.local
</source>

===Step six: Verify domain and DNS entries===
Restart the network service
<source lang=cli>
service bind9 restart
</source>
