allow set remote debug listen host/ip

[bmatusiak]

i would like to debug a remote node-webkit app on a different machine..

current method remote debugging works only on localhost

For example, by running nw --remote-debugging-port=9222, you can open http://localhost:9222/ to visit the debugger remotely.

what about by running nw --remote-debugging-port=9222 --remote-debugging-host=0.0.0.0, you can open http://192.168.1.50:9222/ to visit the debugger remotely on a different machine on same network.

Working with an embedded device this would be a great feature

My linux solution was a work around to reroute external connections to the localhost port

iptables -t nat -A PREROUTING -p tcp --dport 9222 -j DNAT --to-destination 127.0.0.1:9222

depending on your kernel you may also need to enable local routing

 sysctl -w net.ipv4.conf.eth0.route_localnet=1

👍 Would be really useful for visiting on another machine. Or just allow the server to respond to external connections.

I tried to use localtunnel to expose the port and you can see the instances to inspect and see the dev tools. But there isn't any content in any of tabs and nothing reaches the console (it works fine locally). This could be related to this cause of an empty window, "Your proxy settings: bypass localhost in the settings." which is written on the debugging with devtools page

OSX

The ipfw command is no longer available on OSX which is most equivalent to the iptables command @timkalinowski used on linux and is what is mostly used in examples I found on google. But I was able to get this working on OSX Yosemite with pfctl.

1. Open up /etc/pf.conf
2. After this line rdr-anchor "com.apple/*", add the following line

rdr pass inet proto tcp from any to any port 9222 -> 127.0.0.1 port 9222

3. Load the new config: sudo pfctl -ef /etc/pf.conf

To remove the config entry we just added:

netsh
interface portproxy
delete v4tov4 listenport=9222 protocol=tcp
