ORBIT-USER: Virtual access point doesn't work, anyone help?

[Arinto Murdopo]

Hi Kishore,

I think we also can swap step 3 and step 4 to reach the similar effect but
we must wait until all nodes are up and configured with the ruby script. I
put additional codes to print message and notify us when all the nodes are
ready and we at this time we can configure the node using bash or shell
script.

Here is my sample code. Feel free to give comments and suggestion. In this
example, I run the experiment for 60 seconds, but before start the
experiment, the code will wait for 180 seconds, and usually I configure the
nodes using shell script in this 3 minutes period.

Regards,

Arinto
