XX. predvaja:


+

Naloga na hitro:


+ Nastavi uro na strežniku s pomočjo rdate. Napiši program, ki pretvori 24-bitna števila z dvojiškim komplementom v decimalno obliko.

+

Navodila:


+ 1. Iz imenika s slikami virtualnih računalnikov povlecite sliki Student.vdi(klient) in SimpleArbiter.vdi(strežnik).
+ 2. Z VirtualBoxom (ali ostalim programom za virtualne računalnike) ustvarite dva virtualna računalnika in jim kot disk za shranjevanje podajte Student.vdi ter SimpleArbiter.vdi.
+ 3. Zaženite oba navidezna računalnika.
+ 4. Na Student se prijavite z uporabnikom root in geslom kaboom na SimpleArbiter pa z uporabnikom tester in geslom SedemKrogovPekla.

+ +

Prvi del naloge: posodobi uro računalnika s pomočjo rdate.


+ 1. Preverite in si zapišite IP naslov na SimpleArbiter. (ifconfig)


+ 2. Z ukazom sudo apt-get install rdate namestimo program rdate.
+ 3. Na Student z pomočjo rdate posodobi uro računalnika. rdate IP_SIMPLE_ARBITER

+ Opozorilo: NI napaka, če se posodobljen čas ne ujema s pravilnim časom.
+

+


+

Drugi del naloge: napiši program, ki pretvori binarni zapis 32-bitnega števila v decimalnega.


+ Nalogo lahko rešite v Javi ali v Pythonu. Prav tako pa lahko kodo pišete v poljubnem tekstovnem urejevalniku.

+


+ JAVA------
+ 1. Z ukazom nano bintodec3.java ustvarimo in odpremo prazen program s tekstovnim urejevalnikom nano
+ 2. Napišemo program za pretvarjanje 24-bitnega števila z dvojiškim komplementom v decimalno obliko
+

+ 3. Pritisnemo Ctrl+X, nato Y in Enter, da program zapremo in shranimo.
+ 4. Če je še nimamo, naložimo Javo sudo apt-get install openjdk-6-jdk

+ 5. Prevedemo program javac bintodec3.java
+ 6. Lahko ga še zaženemo ter preizkusimo java bintodec3. Na standardni vhod vnašamo 24-bitno število v šestnajstiški obliki

+

PYTHON------
+ 1. Z ukazom nano bintodec3.py ustvarimo in odpremo prazen program s tekstovnim urejevalnikom nano
+ 2. Napišemo program za pretvarjanje 24-bitnega števila z dvojiškim komplementom v decimalno obliko
+
+ 3. Pritisnemo Ctrl+X, nato Y in Enter, da program zapremo in shranimo.
+ 4. Program zaženemo z ukazom python bintodec3.py



+ + +

+

Testiranje

+ 1. Lahko poženemo tester; z ukazom ./run_test.py
+
+ 2. Kot "Upor. Ime" in "Geslo" napišite vaše podatke učilnice. (npr.: "pz1234@student.uni-lj.si" in "geslo123")
+
+ 3. Kot ime naloge vpišite XX.predvaja.
+ 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)
+ 5. Povpraša tudi po IP naslovu SimpleArbiterja, vnesite.
+ 6. Če je šlo vse po sreči, program vrne OK vi pa ste opravili nalogo.
