Abstract
An informatic infrastructure to work in university classrooms is here presented as a solution to problems of cost, maintenance and renewal of computer equipment. The proposal has advantages such as: centralization of the system administration, reduction of the number of software licenses, ensuring the secure access from inside and outside the university network, allowing an efficient use of obsolete equipment, with secure user accounts, unique passwords and data encryption, as well as the use of smart cards for personal identification. A model of actual implementation at a university center is also described.
