No, that's Wake on LAN.

---- Alert on LAN provides notification of the following conditions:System unplugged from power source System unplugged from network Chassis intrusion Processor removal System environmental errors High temperature Fan speed Voltage fluctuations Operating system errors System power-on errors System is hung
With the latest release, Alert on LAN 2 now extends IT capabilities to remotely manage and control their networked PCs:
Remote system reboot upon report of a critical failure Repair Operating System Update BIOS image Perform other diagnostic procedures
And Alert on LAN 2 adds the capabilities for the administrator to take action to correct a failing condition on the IBM PC, increasing IT's flexibility to selectively respond to alerts and further reduce response times. Notification of alert is important, but the capability to act on the information is more valuable. For example, if a machine at a remote location is malfunctioning, the system administrator using Alert on LAN 2 can simply reset or reboot the machine. ---
The feature I really need is to be able to reset the machine remotely when Linux is hung.

Wake on LAN works fine, you just need to enable it in the BIOS.
