I am working on a small project. I have about 20 computers with Ubuntu 10.04 on them, which will be used in a computer lab for elementary, middle, high school and college kids. Some seniors and new computer-users will be using the computers.
I want to lock-down the computers for so children and people who want to play around with PC configuration can use them securely and without breaking them.
I therefore want to restrict user privileges, removing the ability to upgrade, add/install software or otherwise personalize the lab's computers.
The only uses for these computers should be:
access to school websites for access of e-text books (homework assignments)
access to learning-aid websites(such as www.math.com or webster.com)
access/restrictions to applications that are safe and appropriate for the elementary students.
For more senior users only, access to websites for completing applications for re-certifications of say food stamps, medicaid and so on.
Are there any software packages that will let me do this?
