Controller for remote network monitoring

This paper presents a controller for local networks (Intranet) monitoring. The controller can work in two modes. In local mode user can see status of all monitored hosts and servers on LCD. In remote mode the controller sends an alert e-mail or a SMS to the predefined e-mail addresses or GSM phones in two ways: through GSM modem or GSM phone connected to RS232 interface and through SMTP server and e-mail to SMS gateway. If monitored network is not connected to Internet only former method can be used. After an authorized CGI request users can see network status and reboot up to eight hosts if necessary.
