     24The image loaded on the nodes has the tmix tools already installed and in your path.  Also, while booting the first time, a script has generated a set of tmix configuration files for these nodes.  Each time the system boots, a kernel module is automatically inserted to assist in simulating the packet delays.  List the contents of your home directory.
