Diode go client

This is Go client for connecting device through the diodechain mesh network. You can bridge your local resource to the internet with diodechain mesh network. The whole data will be encrypted with ecdh (secp256k1). You can find more details about how diode and its client works in our previous presentations https://github.com/diodechain/presentations and on https://diode.io

COMMANDS
  bns          Register/Update name service on diode blockchain.
  config       Manage variables in the local config store.
  gateway      Enable a public gateway server as is used by the "diode.link" website
  publish      Publish ports of the local device to the Diode Network.
  reset        Initialize a new account and a new fleet contract in the network. WARNING deletes current credentials!
  socksd       Enable a socks proxy for use with browsers and other apps.
  time         Lookup the current time from the blockchain consensus.
  token        Transfer DIODEs to the given address on diode blockchain.
  update       Force updating the diode client version.
  version      Print the diode client version.

Run 'diode COMMAND --help' for more information on a command.

Tunnel ssh using your diode socks proxy

On the client:

$ diode socksd
$ ssh pi@<ADDRESS>.diode -o 'ProxyCommand=nc -X 5 -x localhost:1080 %h %p'

On the destination:

$ diode publish -public 22:22

Use cases

Publish a Local Webserver Article link

Diode is the Swiss army knife of Web3 capabilities! One of the neat things it allows you to do is to publish a local website / webserver to the Internet where anyone can view it. A common reason for doing this is to allow others to see a website that is under development - the development is done locally and can be viewed by collaborators remotely without setting up a staging server and without any IT tools / configuration.

Develop LINE chatbots Article link

Diode is the best tool in connecting LINE’s webhook - it allows you to connect LINE’s message API through Diode’s peer-to-peer network and establish your LINE’s webhook within minutes of time. We're giving everyone a better, more secure, fully decentralized option when developing LINE chatbots.

Enable Proxy Server in Browser

Start the socks server

$ diode socksd

Configure Firefox
1. Open Preferences in menu or type about:preferences in search bar.
2. Goto Network Settings and click Settings button.
3. Setup Automatic proxy configuration URL to the porxy.pac, eg: file:///Users/Guest/diode_client/proxy.pac
4. Click reload then you can proxy request from *.diode *diode.ws to the go client.
Type the website URL and see. You can try http://betahaus-berlin.diode or http://0xc206e1255cbace8ba904daa259d7a5b7f90e2d50.diode and more general:

http://(<MODE>-)<DIODE ADDRESS>.diode<:PORT>

MODES:

"r" read-only
"w" write-only
"rw" read-write (default)
"rs" read-only shared
"ws" write-only shared
"rws" read-write shared

Development

Prerequisite

go >= 1.14
enable go module (see: https://blog.golang.org/using-go-modules)
```
export GO111MODULE=on
```
optional: run dev diodechain locally (see: https://github.com/diodechain/diode_server_ex)

Setup go environment

macOS

Before install golang, please ensure your device meets the requirements (https://golang.org/doc/install#requirements).

You can download the latest binary distribution https://golang.org/dl/ or install from the source code https://golang.org/doc/install/source. Here we are going to install golang with Homebrew.

Install Homebrew

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install Go

$ brew install golang

Then you can check go version meets the requirement (>=1.14).

$ go version

Install dependencies

$ go mod download

Run test

$ make test

Build

$ make

Notes on debugging with pprof

To enable pprof on port 6060 run with diode -pprofport 6060
