I'm assuming that the piece of equipment and the embedded linux board
are two different pieces of equipment?

If so, then have the linux box run something like fping occassionally to
see if your equipment stays alive. Depending on how robust this linux
box is, you may want to consider using 'mon'. Its a software monitoring
solution that would probably greatly speed up your development time.

With mon you can define network services to watch and events that should
occur if a service goes down (ie. If no pings for 3 consecutive tries,
then run special code to reboot hung device + email me a report).
