Wrapper around native traceroute command

node-traceroute's Introduction

node-traceroute

Simple wrapper around native traceroute command. Each hop contains the hosts in that hop and the respective round trip times of each host.

Install

$ npm install traceroute

Usage

The trace method will always return a steam and will call an optional callback when done.

Stream

const Traceroute = require('traceroute');

const trace = Traceroute.trace('google.com');

trace.on('hop', (hop) => {

    console.log(hop)
});

trace.on('done', (hops) => {

    console.log(hops);
});

Async

const Traceroute = require('traceroute');

Traceroute.trace('google.com', (err, hops) => {

    if (err) {
        throw err;
    }

    console.log(hops);
});

This example would write the following to the console if run from my network...

[ { '66.97.5.249': [ 43.206, 43.377, 43.379 ] },
  { '216.182.7.102': [ 43.575, 43.799, 43.808 ] },
  { '216.182.7.165': [ 44.538, 44.613, 44.837 ] },
  { '216.182.7.253': [ 44.846, 56.281, 56.303 ] },
  { '4.53.88.197': [ 57.735, 57.707, 57.891 ] },
  { '4.69.155.254': [ 58.618, 48.514, 48.567 ] },
  { '4.69.134.77': [ 34.167, 44.317 ], '4.69.148.45': [ 44.366 ] },
  { '4.69.141.22': [ 44.542, 44.316, 44.642 ] },
  { '4.69.138.196': [ 44.56, 35.554 ],
    '4.69.138.228': [ 45.035 ] },
  { '4.59.128.18': [ 35.777, 35.827, 45.305 ] },
  { '72.14.238.232': [ 45.621 ],
    '209.85.255.68': [ 45.079, 42.695 ] },
  { '209.85.251.37': [ 32.588, 32.569, 32.657 ] },
  { '209.85.251.9': [ 59.068 ],
    '209.85.254.48': [ 60.287, 75.094 ] },
  { '66.249.94.22': [ 61.565, 62.063 ],
    '72.14.238.242': [ 63.001 ] },
  { '64.233.174.140': [ 96.476, 97.585 ],
    '72.14.239.83': [ 98.656 ] },
  { '64.233.174.191': [ 149.286, 93.528, 94.405 ] },
  { '216.239.43.76': [ 83.901, 85.089, 84.837 ] },
  { '74.125.224.240': [ 84.645, 75.322, 75.585 ] } ]

node-traceroute's Issues

Can you put double quotes around the host string?

I think this would make the output a valid json object.
Would be nice to also include attributes for hostname and client IP.

Disclosure of a security issue

Hello
What email address should I report a security issue to?
The one from npm website failed.

use spawn instead of exec to allow "real-time" feedback

It'd be nice if there was an option to get each hop as traceroute finds them, rather than just a result when it's all done.

i is not defined

When running sample snippet to trace route www.google.com

traceroute = require('traceroute');
traceroute.trace('google.com', function (err,hops) {
  if (!err) console.log(hops);
});

Getting this error.

\node_modules\traceroute\traceroute.js:114
        lines.splice(0,i);
                       ^

Error on windows (variable scope)

I just tried to use your wrapper and got an error (solved it by myself, just for you to correct)
See this code:

    if (internals.isWin) {
        for (let i = 0; i < lines.length; ++i) {
            if (/^\s+1/.test(lines[i])) {
                break;
            }
        }
        lines.splice(0,i);
        lines.pop();
        lines.pop();
    }

"let i" scope is only in the for loop and cant be accessed in lines.splice. Exchange let with var solves the problem
Maybe lines.length instead of i would do it too i think

License?

Hi there

What license applies to this repository? The package json mentions ISC but the repository should specify the license formally.

This is the only thing holding us back from using the repository.

Thanks

Daniel

Hi, i was trying to run the exact code from the example, tracing google.com
However, i've got an error "undefined is not a function" in the line of "dns.lookup(host, function (err) {" inside the module.

Do i need to setup something for the dns lookup?

Allow ICMP ECHO traceroute

Hello,

Would you be receptive to a pull request that made traceroute use ICMP ECHO on Unix platforms as well?

This is the default behavior on Windows, and it would be great if we could use -I on Unix to achieve similar functionality. Makes it easier to work with hosts that are firewalled but allow pings.

Update NPM

You need to update npm to the newest version in this repo. Otherwise you get

trace.on('hop', (hop) => {
^
