Byteball-to-TCP Proxy

This program acts a as TCP proxy on the Byteball network. By default, it serves the current time from telnet://india.colorado.edu (port 13). However, it can trivially be configured to serve any TCP service over the Byteball network.

Features

Incoming text messages are forwarded to the predefined host. Data that arrives as a response is sent back to the guest device. If the open parameter is defined its value is sent to the server immediately after tunnel establishment. The %s part in the open parameter is replaced by the Byteball device address. If the pair parameter is defined its value is executed as a system command after replacing %s with the hex string representation of the used pairing secret and %d with the device address.

Demo

In the Byteball wallet, go to PAIRED DEVICES -> Add a new device -> Accept invitation from the other device. Then scan the following QR code, or input the address manually.

Setup

• npm install

• node bb2tcp.js <host> <port> <name> <desc> <open> <pair> <from>

  host --- host name or the IP address of the TCP server

  port --- port number of the TCP server

  name --- name of this Byteball chatbot

  desc --- initial greeting message shown to freshly paired Byteball devices

  open --- message sent to the TCP server where %s is replaced with the device address

  pair --- command executed on pairing attempts where %s and %d are replaced with pairing data

  from --- source IP address to use when connecting to the TCP server

  Example: node bb2tcp.js india.colorado.edu 13 "Current Time" "Welcome!" "device %s" "notify-send %d:%s" "127.0.0.7"
