    3636The nodes in your '''ssh-config''' file are Docker containers running on (virtual) hosts.  These hosts have ''public'' IP addresses that are routable from the commodity Internet, that's why you can login to the Docker containers of your slicelet.  A port on the public IP address (e.g., 49155) is forwarded to the SSH port (22) on the container's private IP address.  The '''ssh-config''' file contains the names of the virtual hosts and the port forwarding information.   
     
    3838When you run a server on a node in your slicelet, it will listen on the private address.  By default it will only be visible to other nodes in your slicelet.  Docker provides facilities for exposing ports to the public Internet, but this topic is outside the scope of this tutorial.

     40''Note that, to complete this lab, you will later need to find both the ''public'' and ''private'' IP addresses for each node in the slicelet.''
