I am able to set bridged adapter settings and start the sandbox, but I am not able to get the IP address since I am getting some errors.Below are the list of error/warning messages I get when starting sanbox.

1.Ip6tables: No config file [warning]
2.Bringing up interface ehth0:Device does not seem to be pesent.Delayin Initialization [Error]
3.safe mode:call from sandbox.hortonworks.com failed with connection exception while connecting to sandbox.hortonworks.com:8020

I am not sure why these errors are occuring.Please let me know how I can fix these errors.
