Remote Learning Laboratory using Surveillance cameras and VPN Solutions.

This paper describes a solution for the remote teaching of courses and laboratory work in the COVID-19 pandemic. This project implemented several communication solutions so that students have access, from home, to applications running on computers in the laboratory, to the workstations there and can see what happens during the experiments. For this, communication solutions based on VPN (Virtual Private Network) tunneling, gateway based port forwarding or proxy servers were used. In order for the students to see what was happening in the laboratory, during the experiments, a group of surveillance cameras mounted next to each work stand was used. Communication with them was designed to allow more participants to attend these laboratory experiments, regardless of where they connect to the network. To create the system, a server computer was used that runs the LINUX operating system, the paper presenting the practical solutions needed to configure the applications that provide all these services. This system is used, starting with the autumn of 2020 within the department of which the authors are part, to teach an appreciable number of disciplines that require the realization of practical works on computers and laboratory stands.
