15.1.6 Power Cycle any device when a ping request fails
The ping-detect script is designed to run specified commands when a monitored host stops responding

to ping requests.
The first parameter taken by the ping-detect script is the hostname/IP address of the device to ping. Any

other parameters are then regarded as a command to run whenever the ping to the host fails. ping-

detect can run any number of commands.
Below is an example using ping-detect to power cycle an RPC (PDU) outlet whenever a specific host fails

to respond to a ping request. The ping-detect runs from /etc/config/rc.local to make sure that the

monitoring starts whenever the system boots.
Suppose we have a serially controlled RPC connected to port01 on a console server and have a router

following instructions will show you how to continuously ping the router. When the router fails to

respond to a series of pings, the console server will send a command to RPC outlet 3 to power cycle the

router, and write the current date/time to a file:

Copy the ping-detect script to /etc/config/scripts/ on the console server

Open /etc/config/rc.local using vi

Add the following line to rc.local:
/etc/config/scripts/ping-detect 192.168.22.2 /bin/bash -c "pmpower -l port01 -o 3 cycle && date" >

/tmp/output.log &
