Lightbulb How to reboot router/modem when network goes down.


Has anyone done a setup using software/hardware to monitor the internet connection through a router or modem and force a hardware reboot of the modem or router? My cable modem that supplies the internet connection for my server running Redhat occasionally goes down and requires that I power cycle it. Sometimes it's the router that requires the reboot. I've seen devices, though I can't seem to locate one right now, that will ping an IP address and power cycle whatever's plugged into it. The ping occurs at a settable interval and the duration of the power cycle is also settable. The company I work for uses equipment to do the same thing using Network Heartbeat with their Cisco routers. This is rather expensive. Surely there's a daemon that can run on the server and when eth0 loses IP or when the daemon can't ping out, it would send a signal on the RS232 or USB port to activate hardware to cause a reboot of the modem/router or both.

Thanks for anyone that can help.

Couple of things come to mind. I have seen devices that controlled from an rs-232 connection to turn on or off power outlets. Not sure of a specfic item.

Other thought is use one of those X-10 units. Coonect X-10 products as needed and using some command line you can control X-10 modules. Using and X-10 module that plugs into the wall and then plug both router and modem into that. So with a cron script is run and a ping is not completed for a certain number times in a cetain period of time it will issue the off command to the X-10 module and then after say 30secs the on command is issued to the module to power up the modem and router.

Hi, I am trying to overcome the same problem. Did you find a solution? Did you use X10? Was it an easy setup?
