TFTP-Client

A simple TFTP client for Node.Js.
Should not be used in production - first of all: this module is at an early stage (written in less than 12 hours), second: tftp is terrible

Install

As a module

npm install tftp-client

As CLI

npm install -g tftp-client

Usage

Module

var client = new TFTP(port, client) to create a new client.

client.read(filename, callback) to read from the server.
~ The Callback is passed 2 arguments (err, data), where data is the contents of the file.

client.write(filename, callback) to write to the server.
~ The callback is passed 2 arguments (err, bytes), where bytes is the number of bytes sent.

Simple read example:

var TFTP = require('tftp-client');

// Initialize the tftp client
var client = new TFTP(69, 'localhost');

// Read 1.txt from the server
client.read('1.txt', function (err, data) {
	if (err) {
		console.error('ERROR:');
		console.error(err);
		return;
	}

	console.log('Got data (%d bytes). First 100 bytes:', data.length);
	console.log(data.toString('utf8', 0, 100));
});

To install the tftp-client as CLI, run npm install -g tftp-client.
