Description libing wang CLA 2013-02-11 09:29:22 EST 
I found this issue when testing the debug URL link and NPM stuff in McQ's raspberry pi.
We are running node inspector on port number 8900 when user first time uses node debug command.
But in McQ's case, port 8900 is not opened.
We should allow user to assign a port number to node inspector at the server start point, which is defaulted to 8900.
Comment 1 Mark Macdonald CLA 2013-02-11 11:02:10 EST 
The port number here is only used to host the node-inspector web app. In other words, it's this part of the Debug URL you see when you debug a node script:

http://mynodeserver:8900/debug?port=5860
                    ^^^^

Given that this is just a webapp, it would be way less confusing if it was hosted as part of the Orion server, on the same port we normally use (8081, by default).

We need to investigate if node-inspector supports this. Then a user only has to worry about exposing 1 port through their firewall.

Unfortunately node-inspector does not support the same port used by orionode.
