macfromip |
||||
========= |
||||
|
||||
## Synopsis |
||||
|
||||
* Nodejs script; |
||||
* Gets a MAC address from a LAN IP address; |
||||
* Only works on linux, OSX and win32 platforms; |
||||
|
||||
## Code Example |
||||
|
||||
``` |
||||
var macfromip = require('macfromip'); |
||||
|
||||
macfromip.getMac('192.168.2.169', function(err, data){ |
||||
if(err){ |
||||
console.log(err); |
||||
} |
||||
console.log(data); |
||||
}); |
||||
``` |
||||
|
||||
## Installation |
||||
|
||||
``` |
||||
npm install macfromip |
||||
``` |
||||
