Question

I’m trying to create a simple nodejs server to server program.

Here’s what I’m trying to achieve:

-----------¦remote¦-----satellite link-----¦core¦---------
port 6999                port 7000                 port 6999

I need to write node.js code for both ‘remote’ and ‘core’.

Here’s what I have sofar (I’m a very confused now…):

//remote.js
var util=require('util');
var net=require('net');

var input=net.createServer(function(inputStream){
        inputStream.on('data', function(data) {
                util.puts(data);
        });
        var output=net.createServer(function(outputStream) {
                outputStream.pipe(inputStream, {end: false});

                outputStream.on('data',function(dta){
                        util.puts(dta);
                });
        });
        output.listen(7000, '172.16.1.224');
});
input.listen(6999, '172.16.1.224');

Once I have these two forwarding modules (remote and core) up-and-running, I’m hoping to do some packet inspection…

Many thanks in advance,

you need to call createConnection for output stream. Look at my port forwarding code here
