Unix Remote Control (IOT)



Runs Scripts on Mac/Linux remotely.

Why :

I was setting up homebridge (iOS HomeKit Accesory Protocol) on my rasberryPi and after hooking up my IR Blaster, RF Transmitter and other wake-on-lan devices. I wanted my always-on OSX Laptop to also be remotely controlled by my iOS Device. So i ended up writing up a small plugin for Homebridge plugin.

I use this to play itunes, search google and bookmark search results, restart my system, get room temperature using MBP in-build Temp Sensor and adjust airconditioning accordingly, monitor my ec-2 instance stats, sync Spotify Playlist etc.

Homebridge Plugin => homebridge-unixcontrol

How it Works :

This library is directly injected into homebridge with a plugin wrapper => homebridge-unixcontrol

The plugin queries the system using HTTP API and run shell scripts. The shell requires sudo access to shutdown/reboot the system. More commands can be easily be injected. Feel free to PR.

You can ask Siri to execute commands :

Hey Siri, Shutdown my laptop

Hey Siri, play iTunes Playlist

Hey Siri, Good Morning ! // Plays Music, Backups OSX, Search for Google Alerts, Turns Off Air Conditioner

Hey Siri, Capture Laptop Webcam

Hey Siri, Who's using my laptop

Todo :

- [ ] Add Linux Support
- [ ] Add Windows Support
- [ ] Refactor With Promises
- [ ] Replace HTTP API with socket connection.
- [ ] Implement a working Example
- [ ] Security Concerns

Installation :

``
$ npm install -g unix-remotecontrol
`

$3

`
$ unixremote
`

$3

`
$ npm install -g forever
$ git clone https://github.com/sahilchaddha/unix-remoteControl.git && cd unix-remoteControl
$ forever start src/server.js
`

Configuration :

Configuration containing sudo password, port number, logLevel & sessionToken are stored in environment.js in root/src.

To Open Configuration for global module :

`
$ unixremote --config
`

Sample Configuration :

`
//environment.js
var env = {
port: '3000',
pass: 'lol', //sudo password TODO: Secure
logLevel: 'info',
sessionToken: 'f64f2940-fae4-11e7-8c5f-ef356f279131'
}

module.exports = env
`

| Fields | Description |
|--------------------|-------------------------------------------------------|
| port | Port Number to run HTTP Server. |
| pass | System Sudo Password |
| logLevel | Log Level (debug, info, error) |
| sessionToken | Random Session Token for API Authentication. |


NOTE: sessionToken needs to be set as Request Header token




Usage :

After Running the server, You can request

localhost:portNumber/commandType/command

e.g.

`
POST localhost:3000/power/shutdown
{
"time": 10
}
`


`
curl --header "token: f64f2940-fae4-11e7-8c5f-ef356f27913" -X POST localhost:3000/power/logout

curl --header "token: f64f2940-fae4-11e7-8c5f-ef356f27913" "Content-Type: application/json" -X POST -d '{"time":10}' localhost:3000/power/restart

curl --header "token: f64f2940-fae4-11e7-8c5f-ef356f27913" "Content-Type: application/json" -X POST -d '{"destination":"AppleMusic"}' localhost:3000/music/syncSpotify

- [ ] Remote System Format (Need extra OSX Device to test. :P )

Writing Custom Scripts :

Cloning the Repo :

`
$ git clone https://github.com/sahilchaddha/unix-remoteControl.git && cd unix-remoteControl
$ node src/server.js
or
$ npm start
`

Creating Your Router :

You can create your custom router inside Routes folder.

`
//DummyRouter.js
var router = require('express').Router() // Create New Router
var commandService = require('../Services/CommandService.js')

router.get('/hello', function (req, res) {
res.send('Hello')
// Run Your npm commands
// or call Shell Scripts using Command Service

commandService.execute('dummy', 'sayHello', options, function(){})
})

module.exports = router
`

Adding your Router to Valid Routes :

Add your custom router inside routes.js

`
var powerRouter = require('./Routes/PowerRouter.js')
var dummyRouter = require('./Routes/DummyRouter.js')

var routes = [
{
url: '/power',
routerClass: powerRouter
},
{
url: '/dummy',
routerClass: dummyRouter
}
]

module.exports = routes
`

Adding Your Shell Scripts :

You can use Command Service to execute commands :

To add Commands, you can inject your commands inside Commands/commands.js

`
var dummyCommands = {
sayHello: {
command: ['say', 'hello'],
sudo: false // Set as true if command need sudo access
}
}

module.exports = {
// power: powerCommands,
dummy: dummyCommands
}
`

Apple scripts in format .scpt are to be injected inside AppleScripts folder.

You can add command inside commands.js

`
var dummyCommands = {
sayHello: {
command: ['say', 'hello'],
sudo: false // Set as true if command need sudo access
},
runAppleScript: {
command: ['osascript', 'src/Commands/AppleScripts/dummyAS.scpt'],
sudo: false
}
}

module.exports = {
// power: powerCommands,
dummy: dummyCommands
}
`
