Hi On our small network is a file/print server and a mail server, both running 6.3. The file server is connected to a UPS via a serial cable and monitoring software initiates the shutdown process in event of a power failure. The mail server is connected to a simple UPS without any monitoring capabilities, in another part of the building. Is is possible to write a script (or something!) that will be triggered on the file server in event of a power failure and that can telnet into the mail server across the network and initiate the shutdown sequence before the file server shuts itself down? What would such a script look like? I am trying to avoid purchasing another smart UPS just for the mail server. Thanks Grant.
