How to "Ping" from a Node.js app?

Question

I want to ping a server from my node.js app.

Is that doable?

Thanks

Answer 1

You could use exec to call the system ping command

var sys = require('sys') var exec = require('child_process').exec; function puts(error, stdout, stderr) { sys.puts(stdout) } exec("ping -c 3 localhost", puts);

node-net-ping is an awesome module that uses raw sockets.

And, if you are looking for only raw sockets, the same developer has a module for that too: node-raw-socket.
