Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I am working in a new refugee school where the only Internet service available is a slow satellite connection. We are about to set up a computer lab (already have desktop systems and am about to install Ubuntu on them). I'm a newbie when it comes to Linux, but it seems a better alternative than pirated copies of Windows.

I'd like to set up one Ubuntu system, and then mirror that system on perhaps ten to twenty other systems (all of which would be on an ethernet network). I expect to have an internet connection on the one system that I set up, but then it may be difficult to have enough bandwidth to go through all the same steps on the other ten+ systems.

Appreciate any help you can give. -- Harvey

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.If this question can be reworded to fit the rules in the help center, please edit the question.

Seems to be 3 separate questions - "how do I mirror a pre-configured Ubuntu system to 10 or 20 other machines", "how do I cache updates to save bandwidth" and "how do I prevent users from modifying system/installing software". You may get better answers if you edit this question to narrow it down to just one question and ask other two others separately. – Sergey Sep 26 '12 at 4:47

Thank you, pgrytdal. Your answers pertain to another question that was in my original post--how to cash updates so that all 10 or 20 machines don't have to download the same updates. – Harvey Steck Sep 26 '12 at 14:22
No problem! If this worked for you, do you think you could select this as the correct answer? Thanks! – pgrytdal Sep 26 '12 at 22:24

You can setup one machine to your liking.

Then do a Hard disk clone using cloning software (GParted or Norton Ghost or Acronis True Image).

Finally insert the cloned hard drives into all lab machines.

That's it.
