About one year later the school was connected -to Internet and a local area network was installed in the school -building. That was the time to have a server and I knew it must be a -Linux server to be able to fulfil all the wishes of the teachers and -being able to do this in a transparent and economic way, without extra -costs for things like licence and software. So I searched for a -school server system running under Linux and I found a couple of -people nearby who founded 'skolelinux.de'.
