x10ping can monitor network devices by pinging them. Have you ever had a network device such as a router, DSL modem, pc, etc. which will hang every now and then and the only way to get it up and running again was to powercycle it? To make it worst it happens when you are away?
Then x10ping is your answer. With this application you will also need an
X10 controller such as CM11A(US)/CM12U(Europe) and x10 appliances as needed.
X10Ping is a useful application that was written to monitor network devices by pinging them and when found down over a period of time powercycle them. Its a light application with a GUI interface and logging capabilities, which just does the job.

Currently the following X10 hardware is supported: CM11A/C12U, JDS Startgate/TimeCommander/TimeCommnader-Plus and also any device supported by ActiveHome Interface (CM15, CM19A, VT37A, etc).
