NW2: Constantly pinging udp ports on all system in subnet.

[raguay]

NWJS Version : 0.43.3
Operating System : macos 10.14

Expected behavior

Launching nwjs should just show the main window. It should not be actively scanning the network.

Actual behavior

It shows the main window and pings every subnet address in my network. Little Snitch shows:
IP Addresses: 192.168.31.5
192.168.31.146
192.168.31.59
UDP Port: mdns (5353)
Protocol: UDP
Denied Packets: 1
First Activity: 54s ago
Last Activity: 0s ago

Over time, every address in my network is pinged on the udp port.

How to reproduce

Launch nwjs (no package, just the plain program).
Watch it's activity on a network monitor like Little Snitch

This is for the chromecast feature and there is an upstream issue: https://bugs.chromium.org/p/chromium/issues/detail?id=665572

Will look to add a switch to disable it.

Will you check the way to disable it in #6909 ?

I don't know how to do that in nwjs since there isn't a way to get to the internal pages? That also wouldn't be usable to give to others to do. chrome://flags/#media-router Turn off a flag on this page to turning off Chromacast. I would need a way to program that in, not have the user go to an internal page. Richard

I just did it in a normal Chrome browser(latest normal build). It slowed down the number of udp packets to every address, but it didn't stop it. It is now doing a ping every 20s and not every second. There must be something else as well. On Sat, Jan 4, 2020 at 8:48 PM Richard Guay <notifications@github.com> wrote:
