Last active December 17, 2015 01:10
Quick and small tcp proxy written in nodejs. Opens a socket and listens for incoming connections. For every new incoming connection, it will open a connection to the proxied host, and send whatever it gets from either side to the other.
#!/usr/bin/env node
var port_to = 6379;
var port_from = 63790;
var net = require('net');
var server = net.createServer(function(clientSocket) {
var targetSocket = net.connect({port: port_to});
targetSocket.on('data', function(data) {
clientSocket.write(data);
