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

[Muktadir R Chowdhury (mrchwdhr)]

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.

NFD team, any suggestions on scope violation connecting to WebSocket locally?

nfd.conf is same as nfd.conf.sample.

I have confirmed the scope violation issue by disabling scope checking in NFD.
(Commented out lines 116, 227, 320, 406 in daemon/fw/forwarder.cpp.)
Then the browser gets the data.

I have tried that example and the browser does not get anything.

NFD logs show that the interest for /localhost/nfd/faces/list is dropped due to scope violation.

Is your nfd.conf modified from /usr/local/etc/ndn/nfd.conf.sample , especially in the websocket section?


In https://github.com/named-data/ndn-js/blob/master/examples/browser/test-list-faces.html#L47

it says that a Unix socket is used to connect to the local forwarder, but nfd-status shows websocket.

Whoopsie!  (That’s a typo from copying from the Node.js example.) You’re right. it connects with WebSocket. I fixed the comment.

Thanks,

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.
