In this paper, we describe design, practical use and administration of the educational computer system of Department of Information and Computer engineering. This system consists of 45 client PCs and 2 servers which provide various network services, such as e-mail and WWW. Both the clients and the servers are powered by FreeBSD Operating System. The servers are very stable. The system was installed and began to work in April 1998, and no serious trouble has occurred since then.
