I am attempting to create a small ping for proof of concept. I am just
learning node.js. I want the client to send a packet over UDP. The server
should acknowledge it by writing to console and send another packet of the
the same size back to the client.
This is what I have so far.:
Server:
var PORT = 33333;
var HOST = '127.0.0.1';
var dgram = require('dgram');
var server = dgram.createSocket('udp4');
server.on('listening', function () {
var address = server.address();
console.log('UDP Server listening on ' + address.address + ":" +
address.port);
});
server.on('message', function (message, remote) {
console.log(remote.address + ':' + remote.port +' - ' + message);
// I was put a server.send here but it gives me an infinite loop.
});
server.bind(PORT, HOST);
Client:
var PORT = 33333;
var HOST = '127.0.0.1';
var dgram = require('dgram');
var message = new Buffer('My KungFu is Good!');
var client = dgram.createSocket('udp4');
var count = 0;
client.on('message', function (message, remote) {
console.log(12);
});
client.send(message, 0, message.length, PORT, HOST, function(err, bytes) {
if (err) throw err;
console.log('UDP message sent to ' + HOST +':'+ PORT);
count++;
});
Can you guys help me out?
