Set local address for client socket in Node.JS

In my Node.JS application, I initiate a TCP connection to a nearby server.

clientSocket = new net.Socket({});
clientSocket.connect(12345, ip, function () { … });

The socket uses the primary address of eth0, but eth0 has multiple addresses (within the same subnet). Is it possible to define the local address the socket should use?

If you use the factory method which returns a net.Socket, net.createConnection, you can do this.

var net = require('net');

var socket = net.createConnection({
    port: 10011,
    host: 'localhost',
    localAddress: '192.168.0.1'
}, function() {
    console.log('connected');
});
