Description

This repository provides a command line interface for proxying TCP connections with payload output into the console. Payload output can be formatted in different ways: hexadecimal (lowercase and uppercase), decimal, octal and binary.

Installation

From crates.io (Recommended)

Run the following command and wait until the crate is compiled:

$ cargo install logged_tcp_proxy

Now you can run compiled binary:

$ logged_tcp_proxy --bind-listener-addr 127.0.0.1:20502 --remote-addr 127.0.0.1:20582

From git repository

At first clone project using the following command:

$ git clone git@github.com:qwerty541/logged-tcp-proxy.git

Than you need to compile crate by running the following command in project directory:

$ cargo build

Now you can run compiled binary:

$ ./target/debug/logged_tcp_proxy --bind-listener-addr 127.0.0.1:20502 --remote-addr 127.0.0.1:20582
