chubr/portforward repository overview

⁠PortForward

⁠Description

PortForward is a simple TCP port forwarding utility written in Go. It listens for incoming connections on a specified local host and port, and forwards the traffic to a specified remote host and port. This can be useful in scenarios where a service is not directly accessible, but can be reached via a port forwarding proxy.

⁠Building

Clone the repository

Run

go build -o portforward

⁠Usage

Once you have built the PortForward utility, you can use it by running the following command:
