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. +
