+ <h1>Custom rdate</h1>
+ <h2>Short preview:</h2>
+ Set time on server using rdate. Write a program that converts 32-bit numbers into a readable time format.</p>
+ <h2>Instructions:</h2>
+ 1. Downlaod Student.vdi (client) and SimpleArbiter.vdi (server) from the virtual machine images folder<br>
+ 2. Use VirtualBox (or similar) to create two virtual machines, select the virtual disk images from the previous step as hard drives<br>
+ 3. Run both virtual machines.<br>
+ 4. Login on client user:<strong> root</strong> pass:<strong> kaboom </strong> and server user:<strong> tester</strong> pass:<strong> tester</strong></p>

+ <h3>First part: update time using rdate.</h3>
+ <p>
+ 1. Find and remember your server IP address. (ifconfig)<br><img src="../images/bu2.png"><br><img src="../images/bu3.png"><br>
+ 2. Install rdate with <strong>sudo apt-get install</strong> rdate<br>
+ 3. On Student client use rdate to update the machine time <strong>rdate SERVER_IP</strong><br><img src="../images/bu4.png"><br>
+ Note: It's NOT an error if the updated time does not match the correct time.<br>
+ </p>
+ <h3>Second part: write a program that converts 32bit numbers into a readable time format.</h3>
+ <p>
+ You can write a program in Java or Python using your favourite text editor.
+ </p>
+ <h4>Java</h4>
+ <p>
+ 1. We use <strong>nano guliver.java</strong> to create a new blank file<br>
+ 2. Write a program that converts 32bit numbers into a readable time format.<br>
+ <img src="../images/bu6.png"><br><img src="../images/bu7.png"><br>
+ 3. Press Ctrl+X, then Y and Enter to save the program<br>
+ 4. In case you don't have java installed use <strong>sudo apt-get install openjdk-6-jdk</strong><br>
+ <img src="../images/predvaja_clip_image003.gif"><br>
+ 5. To compile use <strong>javac bintodec3.java</strong><br>
+ 6. Run the created program with <strong>java guliver</strong> and input the server IP or name...<br>
+ <img src="../images/bu9.png"><br>
+ </p>
+ <h4>Python</h4>
+ 1. Use nano guliver.py to create a new empty python file.<br>
+ 2. Write a program that converts 32bit numbers into a readable time format.<br>
+ <img src="../images/bu5.png"><br>
+ 3. Press Ctrl+X, then Y and Enter to save our program<br>
+ 4. Run the created program with <strong>python guliver.py</strong><br><img src="../images/bu8.png"><br>
+ </p>
+ <h3>Testing</h3>
+ <p>
+ 1. Use command ./run_test.py to run the tester<br>
+ <img src="../images/s1.png"><br>
+ 2. Your username and password are the same as on ucilnica (npr.: "pz1234@student.uni-lj.si" in "geslo123").<br>
+ <img src="../images/s2.png"> <img src="../images/s3.png"> <br>
+ 3. Name of the task should look like 09.predvaja.<br>
+ 4. When prompted for file path insert your program path (example: if bintodec3.py is in the same folder as program run_test.py run with ./bintodec3.py).<br>
+ 5. Then input your server IP address (SimpleArbiterRDate).<br>
+ 6. If all goes well the program should give you an OK that means you've completed your task successfully.
+ </p>

+ <h1>Custom rdate</h1>
+ <h2>Naloga na hitro:</h2>
+ <p>
+ Nastavi uro na strežniku s pomočjo rdate. Napiši program, ki pretvori 32-bitna števila v čas.
+ </p>
+ <h2>Navodila:</h2>
+ <p>
+ 1. Z imenika s slikami virtualnih računalnikov povlecite sliki Student.vdi(klient) in SimpleArbiterRDate.vdi(strežnik).<br>
+ 2. Z VirtualBoxom (ali podobnim) ustvarite dva virtualna računalnika in jim kot disk za shranjevanje podajte Student.vdi ter SimpleArbiterRDate.vdi.<br>
+ 3. Zaženite oba navidezna računalnika.<br>
+ 4. Na Student se prijavite z uporabnikom <strong>root</strong> in geslom <strong>kaboom</strong>
+ na SimpleArbiterRDate pa z uporabnikom <strong>tester</strong> in geslom <strong>tester</strong>.
+ </p>
+ <img src="../images/bu15.png"> <img src="../images/bu1.png">
+ <h3>Prvi del naloge: posodobi uro računalnika s pomočjo rdate.</h3>
+ <p>
+ 1. Preverite in si zapišite IP naslov na SimpleArbiterRDate. (ifconfig)<br><img src="../images/bu2.png"><br><img src="../images/bu3.png"><br>
+ 2. Z ukazom <strong>sudo apt-get install</strong> rdate namestimo program rdate.<br>
+ 3. Na Student z pomočjo rdate posodobi uro računalnika. <strong>rdate IP_SIMPLE_ARBITER</strong><br><img src="../images/bu4.png"><br>
+ Opozorilo: NI napaka, če se posodobljen čas ne ujema s pravilnim časom. <br>
+ </p>
+ <h3>Drugi del naloge: napiši program, ki pretvori binarni zapis 32-bitnega števila v časovni format.</h3>
+ <p>
+ Nalogo lahko rešite v Javi ali v Pythonu. Prav tako pa lahko kodo pišete v poljubnem tekstovnem urejevalniku.</p>
+ <p>
+ <h4>Java</h4>
+ <p>
+ 1. Z ukazom nano guliver.java ustvarimo in odpremo prazen program s tekstovnim urejevalnikom nano<br>
+ 2. Napišemo program za pretvarjanje 32-bitnega števila v čas<br>
+ 3. Pritisnemo Ctrl+X, nato Y in Enter, da program zapremo in shranimo.<br>
+ 4. Če je še nimamo, naložimo Javo <strong>sudo apt-get install openjdk-6-jdk</strong><br><im src="../images/predvaja_clip_image003.gif"><br>
+ 5. Prevedemo program <strong>javac bintodec3.java</strong><br>
+ 6. Lahko ga še zaženemo ter preizkusimo <strong>java guliver</strong>.Na standardni vhod vnasemo IP naslov ali ime strežnika NTP strežnikom, ki nam pošlje 32 bitno število in pretvori v čas<br><br>
+ </p>
+ <h4>Python</h4>
+ <p>
+ 1. Z ukazom nano guliver.py ustvarimo in odpremo prazen program s tekstovnim urejevalnikom nano<br>
+ 2. Napišemo program za pretvarjanje 32-bitnega števila v čas<br>
+ 3. Pritisnemo Ctrl+X, nato Y in Enter, da program zapremo in shranimo.<br>
+ 4. Program zaženemo z ukazom <strong>python guliver.py</strong><br><img src="../images/bu8.png"><br>
+ </p>
+
+ <h3>Testiranje</h3>
+ <p>
+ 1. Lahko poženemo tester; z ukazom ./run_test.py<br>
+ <img src="../images/s1.png"><br>
+ 2. Kot "Upor. Ime" in "Geslo" napišite vaše podatke učilnice. (npr.: "pz1234@student.uni-lj.si" in "geslo123")<br>
+ <img src="../images/s2.png"> <img src="../images/s3.png"> <br>
+ 3. Kot ime naloge vpišite 09.predvaja.<br>
+ 4. Ko vas program vpraša po poti programa vnesite vašo pot do programa za pretvarjanje. (npr.: če imate program bintodec3.py v isti mapi kot program run_test.py, vnesete: ./bintodec3.py)<br>
+ 5. Povpraša tudi po IP naslovu SimpleArbiterjaRDate, vnesite.<br>
+ 6. Če je šlo vse po sreči, program vrne OK vi pa ste opravili nalogo.
