node-red-node-ping
A Node-RED node to ping a remote server, for use as a keep-alive check.
Install
Run the following command in the root directory of your Node-RED install
npm install node-red-node-ping
Gotcha
On some versions on Raspbian (Raspberry Pi) ping seems to be a root only command.
The fix is to allow it as follows
sudo setcap cap_net_raw=ep /bin/ping
sudo setcap cap_net_raw=ep /bin/ping6
Usage
Pings a machine and returns the trip time in mS.
Returns boolean false if no response received within 5 seconds, or if the host is unresolveable.
Default ping is every 20 seconds but can be configured.
