simple tcp relay without runtime depenencies

tcprelay

a simple tcp relay with no runtime depenencies

purpose:

I wanted to use socat in a docker container built without the required libraries; this produced no joy. This is my solution.

example:

listen for and accept connections to port 2222 on the local machine, connecting each to listening port 22 on host 'remotebox'

tcprelay -lport 2222 -rhost remotebox -rport 22

options:

Usage of tcprelay:
  -4	specify IPV4
  -6	specify IPV6
  -lhost string
    	local listen host (optional)
  -lport string
    	local listen port
  -quiet
    	suppress non-error output
  -rhost string
    	remote host (default "127.0.0.1")
  -rport string
    	remote port
  -verbose
    	output connection state changes
  -version
    	output version

built and tested on:

Linux phobos 4.19.0-21-amd64 #1 SMP Debian 4.19.249-2 (2022-06-30) x86_64 GNU/Linux

install from source:

make build && make install

download release:

Note

I'm presently a total neophyte in terms of releasing go programs. If you're reading this, I'd appreciate kindly feedback.
