How to break a console application about live-android HOT 6 OPEN

Alt + F7 to get back to the GUI

That's not the idea. Alt+F7 is useful to go back to the graphical Android. 
However, if 
you want to execute another command in the console, it's not possible unless 
you 
restart the whole platform (if the previous console command does not end 
immediatly as 
the ping).
However, this is a very minor issue which can be discarded because it's not the 
general purpose of this Android distribution to execute commands in the console.

just restart the system.

Come on, one should not have to restart the system just because live android 
does not 
recognize Ctrl + C (break). That is not very productive.

i think using the ping command should not require a system reboot to stop it. 
Very
unproductive. 

Even I m facing the same problem
