[Nfd-dev] [Ndn-interest] (NDN-js) query localhost from browser?

Thu Jul 21 09:25:48 PDT 2016

I did but no result!

I re-installed NFD and NDN-js.
I am using a WebSocket:

var ws = new WebSocket("ws://127.0.0.1:9696/")
var face = new Face(ws);

I am getting this in NFD log:

1469118300.665993 INFO: [Transport] [id=260,local=ws://[::ffff:127.0.0.1]:9696,remote=wsclient://[::ffff:127.0.0.1]:56441] setState UP -> CLOSING
1469118300.666025 INFO: [Transport] [id=260,local=ws://[::ffff:127.0.0.1]:9696,remote=wsclient://[::ffff:127.0.0.1]:56441] setState CLOSING -> CLOSED

But still no result!

... from this screen shot, it does look like Junxiao using Chrome.

Omar, can you try Chrome?

Hi Muktadir

This example works for me. I have Linux Mint 17 (based on Ubuntu 14.04) and NFD 0.4.1-1-g704430c.

In the source code of this webpage, I notice it's connecting to ws://localhost:9696/ .
It's better to change this to ws://127.0.0.1:9696/ in case the DNS resolver is not resolving 'localhost' to a loopback address. A WebSocket face is considered local only if it uses a loopback address.

Yours, Junxiao

The example works on my Mac OSX, but did not work on Ubuntu 14.04 (VM). Ashlesh was also using Ubuntu 14.04 that's why he is also not getting any data back.

See the example test-list-faces:

Hi all,

I am currently playing with NDN-js library, and I was wondering if it is possible to query the localhost (e.g.  ndn:/localhost/nfd/faces/list) .
I could do that with node using UnixSocket. Is it possible to do it from a browser (knowing that the browser uses WebSockets) ?

Thanks.
