  1. Boot your PC through ltsp (don't press any key during boot)
  2. Login using your account
  3. Open terminal and ssh with your username on os1xx machine (Change xx with your assigned VM number). IMPORTANT: the ssh command is a bit different: ssh -X instead of just ssh.
    $ ssh -X
  4. Create KELAS/NPM/Lab02 directory. For example my KELAS is TESTING and my NPM is 1202000818, replace it with your class (A160, B160, C160, D160, E160, EXT160, MTX160) and student ID.
    $ mkdir -p TESTING/1202000818/Lab02
    $ cd TESTING/1202000818/Lab02/
  5. Do the following to prepare the examination:
    $ wget
    $ chmod +x UPDATE.x
    $ ./UPDATE.x
    $ rm -f UPDATE.x


  1. Please create "WHAT-IS-THIS.txt" file with contents:

    Change [KELAS] with your class, [TANGGAL] with today's date with format DD-MM-YY, [NPM] with your NPM, and [KETERANGAN] with short explanation.
    ZCZC TESTING TGS LAB02 16-02-16

    1. Minimum 2 problems for the topic Penjadwalan Proses Bertingkat (page 3-4)
      Note: Do this OUTSIDE the VM machine. Do NOT wait until the lab session to do this task, do it as soon as possible so that you can focus on doing tutorial tasks instead on the lab session.
      Give the solution pdf named lab02.pdf.
  2. Copy the solution lab02.pdf to your VM. Put it in Lab02 directory. Hint: Use scp but put the origin and destination in reverse to copy it to your VM home directory. Then move the file to your Lab02 directory.

    $ cd ..
    $ tar cvjf TESTING-1202000818-Lab02.tar.bz2 Lab02/
