Weird that it works for you :p

My error was appearing under node v0.4.11 in Ubuntu 11.04 x86_64.

The correct solution pointed out to me on the mailing list was to utilise the callback in the server.listen call found here: http://nodejs.org/docs/v0.4.12/api/http.html#server.listen

The server.listen returns before it's guaranteed to have bound to the port. Seems like on my machine it was not bound and yours it is.

Here's something that's closer to right...

var http = require('http')

var server = http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello world\n');
});

server.listen(1337, "127.0.0.1", function() {
    var client = http.createClient(1337, '127.0.0.1');
    var req = client.request('GET', '/', {});

    req.end();
    req.on('response', function(res) {
        res.on('data', function(chunk) {
            if (!this.body) this.body = '';
            this.body += chunk;
        });
        res.on('end', function() {
            console.log(this.body);
            server.close();
        }); 
    });
});
