A large part of the school will be tutorials with computer exercises. Participants are expected to bring their own laptops with an X environment. Please let me (gero.flucke@desy.de) know immediately if you urgently need a computer provided by DESY instead (even if you have already marked this at registration!).
The software needed for the tutorials will be provided in the form of a Virtual Machine. To run a virtual machine you first need a program capable of doing this for you. For the school we have chosen the program VirtualBox.
It is mandatory to prepare your laptop in advance of the school.
Installing VirtualBox
* VirtualBox is available for various platforms here, including the most commonly used versions of Linux, Mac OS X and Windows. A detailed list of supported host operating systems can be found here.
* Download the appropriate package for your architecture and operating system. If you are running Windows or Mac OS X, install it as any other "point and click" software. Details on the installation for Linux are available here.
* Please install VirtualBox version 4.1.2 or later, or upgrade your existing installation (You might try with 4.0.12 if you have that already installed - it seems to do well on MacOS, but no guarantee...).
Running the virtual machine in VirtualBox
Once you have the program VirtualBox running you can run the school's virtual machine inside of VirtualBox. To do this, follow the instructions below (name of buttons etc. as for VirtualBox 4.1.2 on ubuntu 11.04 - small differences seen on a Mac with 4.0.12):
* Import the school's virtual machine
- Make sure you have about 4 GB of free disk space
- Download the StatSchool_Oct2011.ova file from ftp://ftp.desy.de/pub/school/
(via browser or wget ftp://ftp.desy.de/pub/school/StatSchool_Oct2011.ova etc.)
- Note: Some VirtualBox installation seems to have a problem with the fact that the .ova file was renamed,
see http://funnymonkey.com/do-not-rename-your-virtualbox-ova-file. If you hit this problem, rename it back
to StatSchool.ova before the next steps.
- Start VirtualBox
- Click on `File', then on `Import Appliance'
- Click on the `Choose' button and select the .ova file you just downloaded
- Click on `Next', then on `Import'
- Select the (StatSchool) virtual machine from the left panel of VirtualBox's main menu
- Click on Network in the right panel.
- In the `Adapter 1' tab, click on `Advanced'
- Next to the mac address field click the green arrows symbol.
- Observe that the mac address has changed value and press OK.
* Start the school's virtual machine and log in
- Select the (StatSchooll) virtual machine from the left panel of VirtualBox's main menu
- Click the start button (green arrow)
- When the virtual machine is starting, read the information about capturing of the mouse and the keyboard
- Wait for the machine to complete start up
- At the login manager ("Welcome to statistics-school"), select "Terascale Statistics School" as user name.
- In the middle of the bottom panel you can choose the session type - you might want to use
'Ubuntu Classics (No effects)' if you are not used to their new window manager.
- Enter the password "Sch00l" (with two zeros...).
Access to the host filesystem
* Create a new empty directory on the host, which will be shared with the guest system
* In the VirtualBox window frame for your VM, select "Shared Folders" under the "Devices" menu
(to have the Devices menu visible, make sure the virtual machine window in VirtualBox is active).
- Click the add-button (might appear as small icon of a folder with a green cross).
- Enter the path of the empty directory you have created on the host machine in the "Folder Path".
- Type "hosthome" in the "Folder Name", do not leave the default!
- Select "Make Permanent".
- Click OK.
* In the VM's terminal window do
sudo mount -t vboxsf -o uid=1000,gid=1000 hosthome /mnt
Now you can access your files on your host machine inside the VM under the /mnt directory.
* Every time you start the VM again, you need to re-run
sudo mount -t vboxsf -o uid=1000,gid=1000 hosthome /mnt
* Remark: if you would have choosen "Auto-mount" together with "Make Permanent" above and restarted
the virtual machine, the directory would be mounted as /media/sf_hosthome, being accessible only via sudo:
- sudo ls -l /media/sf_hosthome
- sudo cp /media/sf_hosthome/afile.txt ~/
- etc.
Keyboard Mapping
* Use the command "setxkbmap de" in the VM terminal to change from the standard American keyboard layout
to a German one if needed (us gives American, es Spanish , pl Polish, se Swedish etc. )
Simple Tests and Further Preparations
* ROOT
- open a terminal and start root
- check whether you can open a TBrowser (e.g. typing new TBrowser)
- note that we use ROOT 5.30.02 that comes with new default style settings
- you might want to create your favourite .rootrc or .rootlogon.C
(but please note that this might change the result of tutorials...)
* Editing
- at least emacs, pico, vi and nedit are installed
- configure your favourite editor such that it behaves similar to what you are used to
