Custom rdate

Short preview:

- Set time on server using rdate. Write a program that converts 32-bit numbers into a readable time format.

Instructions:

- 1. Downlaod Student.vdi (client) and SimpleArbiter.vdi (server) from the virtual machine images folder
- 2. Use VirtualBox (or similar) to create two virtual machines, select the virtual disk images from the previous step as hard drives
- 3. Run both virtual machines.
- 4. Login on client user: root pass: kaboom and server user: tester pass: tester

First part: update time using rdate.

- 1. Find and remember your server IP address. (ifconfig)

- 2. Install rdate with sudo apt-get install rdate
- 3. On Student client use rdate to update the machine time rdate SERVER_IP

- Note: It's NOT an error if the updated time does not match the correct time.
-

Second part: write a program that converts 32bit numbers into a readable time format.

- You can write a program in Java or Python using your favourite text editor. -

Java

- 1. We use nano guliver.java to create a new blank file
- 2. Write a program that converts 32bit numbers into a readable time format.
-

- 3. Press Ctrl+X, then Y and Enter to save the program
- 4. In case you don't have java installed use sudo apt-get install openjdk-6-jdk
-
- 5. To compile use javac bintodec3.java
- 6. Run the created program with java guliver and input the server IP or name...
-
-

Python

- 1. Use nano guliver.py to create a new empty python file.
- 2. Write a program that converts 32bit numbers into a readable time format.
-

- 3. Press Ctrl+X, then Y and Enter to save our program
- 4. Run the created program with python guliver.py

Testing

- 1. Use command ./run_test.py to run the tester
-
- 2. Your username and password are the same as on ucilnica (npr.: "pz1234@student.uni-lj.si" in "geslo123").
-
- 3. Name of the task should look like 09.predvaja.
- 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).
- 5. Then input your server IP address (SimpleArbiterRDate).
- 6. If all goes well the program should give you an OK that means you've completed your task successfully. -

Custom rdate

Naloga na hitro:

- Nastavi uro na strežniku s pomočjo rdate. Napiši program, ki pretvori 32-bitna števila v čas. -

Navodila:

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

Prvi del naloge: posodobi uro računalnika s pomočjo rdate.

- 1. Preverite in si zapišite IP naslov na SimpleArbiterRDate. (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 časovni format.

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

Java

- 1. Z ukazom nano guliver.java ustvarimo in odpremo prazen program s tekstovnim urejevalnikom nano
- 2. Napišemo program za pretvarjanje 32-bitnega števila v čas
- 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 guliver.Na standardni vhod vnasemo IP naslov ali ime strežnika NTP strežnikom, ki nam pošlje 32 bitno število in pretvori v čas

-

Python

- 1. Z ukazom nano guliver.py ustvarimo in odpremo prazen program s tekstovnim urejevalnikom nano
- 2. Napišemo program za pretvarjanje 32-bitnega števila v čas
- 3. Pritisnemo Ctrl+X, nato Y in Enter, da program zapremo in shranimo.
- 4. Program zaženemo z ukazom python guliver.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 09.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 SimpleArbiterjaRDate, vnesite.
- 6. Če je šlo vse po sreči, program vrne OK vi pa ste opravili nalogo. -
