I'm working as volunteer at a primary school where exist close to 23 machines (used by teachers, students and employees).
Do you guys know if there is some open source project to control all these machines (Ubuntu 12.04 LTS) as if it were one?
I mean we need to update all these machines at once and periodically install new software.
Note1: all machines are connected in LAN and we have full access.
Note2: some tutorial or guide would be awesome.
