an easy way to port forwarding using ruby

Port Forwarding using Ruby

port-forward forwards(obviously) an incomming TCP connection on a specific port to another local/remote port

Note: Type 'exit' or 'quit' to exit the script safely (wont exit your netcat session)

OS Support

• port-forward.rb
  • Support all OS's if ruby installed
• port-farward.exe
  • Support Windows (Portable - no ruby required)

Usage

ruby port-forward.rb <LPORT>:<RHOST>:<RPORT>

Example

$> ruby port-forward.rb 80:localhost:8080

or

$> ruby port-forward.rb 4444:192.168.100.17:4444

ruby-port-forward's Issues

rport and lport need to be switched

rport_server = TCPServer.new('0.0.0.0', rport) <-should be lport
 while true
      Thread.new { wanna_exit }
      rport_client = rport_server.accept
      lport_server = TCPSocket.new(rhost, lport) <-should be rport

rport_server is the localhost server, listening on lport.
lport_server is the client, that connects to rhost, rport.
I'm still not satisfied with the name "lport_server". But that's a matter of opinion.

Forward connections to two different servers

Hi @KINGSABRI, could this script be used to forward TCP/IP messages to two different servers?
