//forwarding a local client port to server port (only send)
// just run:
// $ netcat -l -k -p <REMOTEPORT>
// on server side, and replace define(REMOTEPORT,XX) with same number port that you've used on netcat's
// command line.
// Then, run this script and open your browser with
http://localhost:
// you should see the plain http browser query on your remote SSH2 server terminal
// As in this example, just use:
// $ netcat -l -k -p 8081
// and type
http://localhost:8888 on your browser
// Note: this script is only illustrative. Is not something to be used as is in the real world.
