In working through the SimpleWebServer.js from @Derek_Molloy new book, when I run the simple node.js test it launches on the USB interface 192.168.7.2 yet I was connected to my BBB via WiFi with a 192.168.1.x ip address and the USB disconnected . Where does the nodejs runner pick up the ip address? from the ifconfig? A configuration in cloud9, or ??? The SimpleWebServer.js does not run on the WiFi address, but if I plug in the USB it does run off it’s interface.

I’d rather use the WiFi and a power supply. Ideally the launch process would detect the active interface.

Note: I’m using a young release

The way https://github.com/derekmolloy/exploringBB/blob/master/chp02/SimpleWebServer.js is written, it simply listens to on all interfaces on port 5050. Documentation for the API he uses is at http://nodejs.org/api/http.html#http_server_listen_port_hostname_backlog_callback

Doh! It’s working now on both interfaces.

Doh, actually no it’s not. Can’t figure out how to add a screen shot to the comment or my original post. Started a new thread in the support section of the beaglebone community.
