Ofris/Deepfreeze for Linux
by Brian Beaton - Tuesday, 26 October 2010, 11:49 PM
 

Michael ... I watched the OFRIS install and operation video that you posted. Very impressive and useful program for teachers and IT computer technicians working with computer labs [smiles].

The video says to run ofris-en at the Ubuntu prompt to freeze and unfreeze the computer. Okay ... some questions ...

  1. how do I get to the Ubuntu prompt to run this program (I am a new user of Ubuntu and only installed the dual boot option on my laptop recently and what I have is the Ubuntu desktop to work with)?
  2. does this mean that OFRIS comes with the latest version of Ubuntu or does it need to be downloaded?
  3. once OFRIS is run and the computer is locked, it sounds like students or other user of the computer will need a USB Memory Stick to store their files that they want to keep. Are there any other ways for users of the computer to save and store their files and work on the computer?

Hey Brian,

Thanks for the great questions - here are the answers to the best of my ability:

1)For the program to be run, it needs to be downloaded. First access terminal: click applications -> accessories -> terminal is at the end of the list. Then type in the following:

sudo add-apt-repository ppa:tldm217/tahutek.net

then type in

sudo apt-get update

then

sudo apt-get install ofris-en

Afterwards, type in

ofris-en

Then ofris will be running in the terminal box. Make your selection (I would suggest creating another user first such as "student" and applying ofris from the administrator. Please note only the admin. can run ofris from terminal, not another user).

2) No, I am trying my best to tell the edubuntu guys to include ofris in the latest update, but it's a relatively small program to download. So normally it is not included in ubuntu.

3) No, unfortunately like many library computers, you will have to bring a usb to save your work. Ofris protects all system files for the selected user, so allowing changes to a single directory isn't allowed...yet. Perhaps a development for the future?

Re: Ofris and Edubuntu in Sandy Lake

Michael ... GREAT report about your trip to Sandy Lake. Thanks for sharing that one with everyone. It sounds like you keep on making more work for yourself [smiles] ... that is good ...

Now that the computer lab in Sandy Lake has Ofris and Edubuntu on the computers, does this mean that the only way for a student to save their work is to have a USB memory stick available? If so, is the school providing all the students with their own memory stick?

It seems to me that the real test about how well accepted Edubuntu is for the elementary students and teachers is to do some follow up with the school and teachers. Do you have a plan on how you might follow up on your work with the teachers you have been working with in Sandy Lake and Pikangikum?

Another important step will be if you are able to assist other people to successfully install and use these tools in other schools across the district. Have you met with Angie Morris, the First Nations Youth IT Employment Coordinator to discuss ways for the youth workers to use the information you have been creating with the computers in their community schools?

Brian, thanks again for all the support!

As for your questions:

  1. Unfortunately, OFRIS (like deepfreeze software) doesn't allow the saving to a particular folder.  I have left memory sticks with Michelle in Sandy Lake - most likely the teacher will collect the USBs at the end of the period (unless they can take it back home to work on).
  2. I have sent emails to Sandy Lake and Pikangikum - I was hoping before Christmas break I would send them a teacher and student survey asking their thoughts/recommendations on ELDER in their classroom.  This could be used to help develop ELDER further on in the future.   
  3. I will definitely ask Angie about this - I think I did talk to her about how we could train or guide youth workers in the communities to install distributions in their lab.  Perhaps we can set up videoconferencing sessions? 

Thanks again!
