LANOff is a network monitor and shutdown utility which monitors up to four remote computers from a client computer and optionally shuts down the client and specified remote computers when the network fails or the specified computer shuts down. It also supports fixed activation and shutdown initiation times plus a fixed delay before shutdown initiation. Various parameters can be set via the configuration screen. LANOff was designed to be used in conjunction with AllOff or ProcOff to enable a backup server to be shut down automatically once several computers on a local network had completed their backups. It can also be used on it's own. LANOff supports all the normal shut down modes. The program operates by interrogating each remote computer via a small slave program once a second. Up to four remote computers can be monitored or controlled with shutdown being initiated when connection to all computers is lost. Uses of LANOff include monitoring up to four computers connected to a server shutting down the server when it is no longer needed or shutting down up to four computers connected to a server when the server shuts down. It can be started at a fixed time, from a command line, on start up or manually. See LANOffhistory for details of the changes in this version. LanOff is part of the JSutils group of software utilities which have a theme of energy conservation. Requires a registration code (free for personal non commercial use).
