  31 Default HOST is 10.0.0.1 or 10.2.0.1 if they are the gateway, otherwise
  32 it must be specified.

  34 Note, use -m "''" to send an empty mac arg. When we get a new enough
  35 bash, we can use ${@@Q} to properly pass an empty var.

  38 Note, if we dont have internet yet, then just download the bash package,
  39 scp it over manually and install it, eg:
