GameLinkSafeCLI

Introduction

GameLinkSafeCLI is an Open Source project that aims to connect 2 machines through WebRTC and share ports. It is an alternative to ngrok/hamachi with TCP/UDP support. No account required.

This programm is a CLI, may not be easy for all users. There isn't a GUI implementation at the moment.

You can use the software as it comes but if you are behind a strong firewall, a strict NAT or searching for more security you may want to have your own TURN server. If this is the case you can rent a TURN server or self-host it using coturn

Features

Instructions

Shows all commands with examples

./gamelinksafecli --help

Example of connection:

Host shares tcp 8000 port

./gamelinksafecli --role host --protocol tcp --port 8000

Client setup tcp tunnel on port 5000

./gamelinksafecli --role client --protocol tcp --port 5000

Now it should appear some messages with instructions and connection codes. Finally copy and paste the generated codes between peers.

The resulting connection will work like this:
Host (TCP 127.0.0.1:8000) <-> Client(TCP 127.0.0.1:5000)

Advanced Config

By default GameLinkSafe uses a dynamic public STUN server list but you can specify STUN / TURN servers using a servers.yml file in the same directory as the executable.

This is an example of use:

# file: servers.yml

iceServers:
  # Public STUN servers
  - urls:
      - stun:stun.l.google.com:19305
      - stun:stun.l.google.com:19302
      - stun:stun.ipfire.org:3478
  # TURN server with UDP transport
  # - urls:
  #     - turn:turn.example.com:3478
  #   username: user1
  #   credential: pass1

  # # TURN server with TCP transport
  # - urls:
  #     - turn:turn.example.com:3478?transport=tcp
  #   username: user2
  #   credential: pass2
