I administer about 6 computers at a school. The computers are very old -- they used to be running Windows 98 -- but they are still usable and are now running Ubuntu. I also have 2 more modern computers running Windows XP.
I am trying to run scratch on these computers, which I currently have accomplished. The problem is, these computers constantly break down and need to be replaced. The IT of the school doesn't allow them to be connected to the internet, but I want to share files between these computers so that the files are stored in one place. Ideally, if one computer has to been replaced, there won't be missing files. Dropbox isn't an option because it required internet.
Is there a way to have the 4 Ubuntu computers, and the 2 Windows XP computers (none have internet) to connect to a computer running Ubuntu Server just by ethernet cables? Each computer would have its own dedicated ethernet cable connecting it to the server.
