tftp-client

Very simple TFTP client

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

npm install tftp-client

npm install -g tftp-client

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 (errdata) {
    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.

tftp-client <hostname> (read|write) <filename> [<port>]

  • hostname - Hostname of tftp server
  • read|write - Wether you want to read or write
  • filename - Path to the file you want to read or write
  • port - Optional. Defaults to 69

Example: tftp-client localhost read 1.txt
