Bind to 0.0.0.0 instead of 127.0.0.1

[leebrooks0]

I was trying to run my Padrino app from a tablet via a wi-fi network and I could not connect. I asked here http://unix.stackexchange.com/questions/105164/connecting-to-localhost-via-system-ip-address and they said that to bind port 3000 (or any other...) to all IPs you need to use an IP of 0.0.0.0. In my question on the Unix forum I never stated that I was using Thin with Padrino, and Padrino always seems to bind to 127.0.0.1.

a) What is the difference between thin start and padrino start (or passenger start and padrino start etc etc.)?
b) Can I get padrino to bind to 0.0.0.0?

a) thin and passenger are full-blown web servers, padrino start is built-in padrino script which loads an app and uses Rack::Server to serve with it.
b) use padrino start -h 0.0.0.0 if you want temporary development run, configure something bigger to run long-term development or production.
