Quick task:

+ Connect to VPN with OpenVPN. Enable access to files through NFS and copy them through SMB.

Navodila:

+ 1. From Directory with images of virtual computers drag twice the picture SimpleArbiterVPN and VPNClient.
+ 2. With VirtualBoxom (or other programs for virtual computers) create two virtual computers and give them VPNCLient.vdi and SimpleArbiterVPN.vdi as disk for storage.
+ 3. On both set two network interface(NAT and Internal) and run them.
+ 4. On both VM login with username root and password kaboom .

First part: Set up OpenVPN on SimpleArbiterVPN and VPNClient.

Settings on the server:

+ 1. Download packages uml-utilities -> to adjust the virtual network interfaces and packet (openvpn). example: sudo apt-get install openvpn
+ 2. The new virtual network interface create with tunctl and specify IP with sudo ifconfig tap0 10.P.Q.R netmask 255.255.255.0
+ 3. Then generirate common key (you will share that key with client) with the command: openvpn --genkey --secret vpnkljuc.key
+ 4. On server set the configuration file tap0.conf, which should contain (split by lines) "dev tap0","proto tcp-server", "secret vpnkljuc.key"
+ 5. Run openvpn with openvpn --config /some_directory/somewhere/tap0.conf
+

Settings on the client:

+1., 2. steps are the same as the settings on the server
+3. Create configuration file tap0.conf, which should contain (split by lines) "remote IP_OF_YOUR_VPN_SERVR", "dev tap0", "proto tcp-client", "secret vpnkljuc.key"
+4. On OpenVPN server connect to openvpn --config /some_directory/somewhere/tap0.conf
+

Second part: write a program, which converts the binary record 32-bit number in decimal.

+ The task can be made in Java or Python. You can also write code in any text editor.

+ JAVA------
+ 1. With command nano bintodec3.java create and open empty program with text editor nano
+ 2. Write a program for converting 24-bit number in two's complement into a decimal shape
+

+ 3. Click Ctrl+X, then Y and Enter, that the program is closed and stored.
+ 4. If you don't have it, install Java sudo apt-get install openjdk-6-jdk

+ 5. Compile program javac bintodec3.java
+ 6. You can run and test the program java bintodec3. On the standard input are entered 24-bit numbers in hexadecimal format

PYTHON------
+ 1. With command nano bintodec3.py create and open empty program with text editor nano
+ 2. Write a program which converts 24-bit number in two's complement into a decimal shape
+
+ 3. Click Ctrl+X, then Y and Enter, that the program is closed and stored.
+ 4. Start the program with command python bintodec3.py

+ + +

Testing

+ 1. You can start the test program with command ./run_test.py
+

+ 2. For "Upor. Ime" and "Geslo" write your username and password. (example.: "pz1234@student.uni-lj.si" and "geslo123")
+

+ 3. For the name of the task write XX.predvaja.
+ 4. When a program asks you for path, enter your path to program for converting. (example.: if you have a program bintodec3.py in the same map as program run_test.py, enter: ./bintodec3.py)
+ 5. When he asks you about IP address SimpleArbiterja, enter.
+ 6. If the program returns OK your task is finished.
