Ubuntu Ghost account

[sagarsiddhpura]

I want to install Ubuntu 9.04 in all the computers of my college's internet lab.

But owing to some strict requirements of lab i could not install it:

> The user should not be able to access local drives (Currently deployed by software "Folder LockIT")
> The user should not be able to change local configurations(Themes, Wallpapers etc).
> The user should not be able to permanently store files or folders. (Currently deployed by software "Deep Fridge")
Whenever logout is performed the files should be removed and system should be restored to some default state.(As done by software "Deep fridge")
Users should be able to save files temporarily on desktop.

I am not able to configure such account in Ubuntu using standard user manager.

Advance Thanks for help.

I take it you are doing this without permission then...

I think they are saying they cannot install Ubuntu on the lab computers without being able to replicate the above security standards.

I've never particularly thought about how to keep a user from doing things to their own account, but off the top of my head for your questions...

1. New user accounts shouldn't have access to anything outside their home folder by default, and it's easy enough to remove read/write permissions from any file you like.

2. Remove write permissions from the config files.

3. Mount the users home folder to a temporary file system.

EDIT: Just to note on wallpaper and themes. Settings for these are stored in the user's home directory. If you're mounting the home directory to a tempfs, then even if they change the wallpaper or whatnot, it will reset to the default settings on reboot.

I have contacted the System administrator and i want to deploy Ubuntu officially.

Hmmmm - didn't I recently see this topic, in an almost identical form, on another forum?

As I recall, the most promising answer on that forum was to investigate "kiosk" mode. So, sagarsiddhpura, did you try kiosk mode? Did it work?
