node-tcp-proxy

node-tcp-proxy

A simple TCP proxy that may be used to access a service on another network. An extensible replacement for socat when used thus

socat TCP-LISTEN:port1,fork TCP:host:port2

port1 is where socat listens for incoming requests. host and port2 are the host and port where the actual service is listening at.

To achieve the same with node-tcp-proxy

tcpproxy  --proxyPort port1 [--hostname [IP]] --serviceHost host --servicePort port2 [--q]

Optionally, hostname specifies the IP address to listen at. Node.js listens on unspecified IPv6 address :: by default.

npm

Install node-tcp-proxy from npm, thus

sudo npm install -g node-tcp-proxy

Programming Interface

To create a proxy in your own code

var proxy = require("node-tcp-proxy");
var newProxy = proxy.createProxy(8080, "host", 10080);

To end the proxy

newProxy.end();

hostname can be provided through an optional fourth parameter e.g. {hostname: 0.0.0.0} to createProxy. Console output may be silenced by adding quiet: true e.g. {hostname: 0.0.0.0, quiet: true}.
