rcommander_pr2 with simulated robot [closed]

edit

Has anyone used rcommander_pr2 with the simulated pr2 robot?

As far as I can tell from the documentation (http://www.ros.org/wiki/rcommander_pr2/tutorials/Starting%20RCommander%20PR2 ) it seems to only work with the real robot out of the box.

I was wondering if there was a fork or set of launch files available somewhere for use with a simulated pr2 instead.

Running the launch file as instructed on the tutorial gets me an error of:

cannot resolve host address for machine [c2]
